Science Tuesday: A Warp in Space-Time, Our Solar System Has More Planets, and the Evolution of the Color Blue

Happy Tuesday, Aledan Merfolk! It’s Science Newsday and we have a lot to cover, so let’s get right to it!

Easter Island culture in decline before Europeans arrived, study suggests: After examining obsidian tools at archaeological sites on Easter Island, researchers say environmental factors may have played a role in the decline of the indigenous Rapa Nui culture long before Europeans came in 1722. Researchers gleaned information about climate and soil history that indicated increases and declines in land use. “It is clear that people were reacting to regional environmental variation on the island before they were devastated by the introduction of European diseases and other historic processes,” said anthropologist Thegn Ladefoged, co-author of the study published in the Proceedings of the National Academy of Sciences.

Images reveal chaotic origins of Andromeda, researchers say: Images of the Andromeda galaxy taken by the Keck Telescope in Hawaii and the Hubble Space Telescope have revealed its chaotic history, according to a study presented at an American Astronomical Society meeting. The study indicates that Andromeda’s younger stars move in a relatively ordered way with similar velocities around the galaxy’s center, while older stars move in a more disordered fashion with varying velocities. Researchers say one explanation would be that thick, clumpy gas formed Andromeda’s disc, and that its oldest stars were created during this time.

Record-breaking X-ray flare detected at Milky Way’s central black hole: A massive X-ray flare erupted from the supermassive black hole at the center of the Milky Way in September 2013, according to astronomers, who say it was the largest ever seen in that region. NASA’s Chandra X-ray Observatory spotted the flare, 400 times brighter than the region’s normal level of radiation. A second flare was spotted in October 2014, according to findings presented at an American Astronomical Society meeting.

Tiny fossil may be common ancestor to both bony, cartilaginous fish: A tiny, 415 million-year-old fish skull is giving researchers clues about the origins of all jawed vertebrates, according to a study published in Nature. Janusiscus schultzei has characteristics of bony fish and cartilaginous fish. Researchers say the fish is likely a common ancestor of the two groups of fish and may help them learn more about what the earliest common ancestor looked like.

New insecticide-resistant mosquito found in Mali: A new hybrid mosquito resistant to insecticides has been discovered in Mali. Anopheles gambiae, considered the biggest culprit in the spread of malaria in West Africa, has been mating with Anophele coluzzii, creating the hybrid and raising fears that malaria infections, which has been declining in recent years, could increase. “Growing resistance has been observed for some time. Recently it has reached a level at some localities in Africa where it is resulting in the failure of the nets to provide meaningful control, and it is my opinion that this will increase,” said medical entomologist Gregory Lanzaro, lead researcher of the study published in the Proceedings of the National Academy of Sciences.

Groove in human brains set us apart from other primates, study finds: An asymmetrical groove that runs deeper along the right side of the human brain than the left sets humans apart from chimps, whose brains don’t have this feature, according to a study published in the Proceedings of the National Academy of Sciences. The purpose of this groove is still unknown. “Asymmetrical brain landmarks may be key features to understand what is so specific in our species. We think that [this asymmetry] is related to either speech or social cognition, which are both abilities for which humans outperform other primates,” said researcher Francois Leroy.

Astronomers measure distant binary pulsar just before it vanishes: Astronomers measured a distant binary pulsar system just before it blinked out of sight, hidden by its own sort of invisibility cloak, according to research published in the Astrophysical Journal. One of the closely orbiting neutron stars of the J1906+0746 system has a wobbling axis and gives off a beam of radio waves every 144 milliseconds, causing such extreme gravitational interactions that it creates a warp in space-time, briefly glimpsed by scientists. “By precisely tracking the motion of the pulsar, we were able to measure the gravitational interaction between the two highly compact stars with extreme precision,” said researcher Ingrid Stairs.

This sounds like some crazy Doctor Who science going on!

Mich. neighbors find mastodon bones during backyard excavation: A pair of Michigan neighbors excavating one’s backyard turned up 42 mastodon bones, including leg, hip and shoulder bones, dating back 10,000 to 14,000 years. Paleontologists helped the neighbors dig up the fossils and believe the remains are those of a 37-year-old male mastodon that may have been butchered by ancient humans because of tool marks found on the bones. Daniel LaPoint Jr. and Eric Witzke each plan to keep a few of the bones to preserve the memory of their find.

Humans in Americas long before dogs, study suggests: Humans appear to have been in the Americans thousands of years before dogs showed up about 10,000 years ago, according to a study published online in the Journal of Human Evolution. Researchers studied DNA from ancient dog remains, and their findings suggest not only the canines’ late arrival but also a greater diversity among ancient dogs, whose long relationship with humans can help scientists learn more about human migration. “They can be a powerful tool when you’re looking at how human populations have moved around over time,” said biologist Kelsey Witt, lead study author.

Study: Tools likely the first topic of conversation between early humans: Early humans likely talked about tools when they started having verbal conversations between 2.5 million and 1.8 million years ago, a study published in Nature Communications suggests. “We suggest that the use of tools drove the evolution of language, and it seems likely that ‘words’ for things other than current emotional states would have been very useful for learning to knap,” said Thomas Morgan, lead study author. Researchers tested five ways to convey to students how Oldowan stone-knapping tools were used and found that verbal communication was the most successful.

Shark born in tank with only females does have a dad, study finds: The mystery behind the birth of a brownbanded bamboo shark born in 2012 in a tank containing only three adult females has been solved. The female sharks were acquired by the Steinhart Aquarium in San Francisco in 2007 from the Aquarium of the Pacific in Long Beach, Calif., where they had been kept with male sharks. Scientists studied various scenarios before determining that the mother shark had stored the father’s sperm for years, according to findings published in the Journal of Fish Biology.

Naps key to helping babies form memories, study finds: Napping may help babies form memories, according to a study published in the Proceedings of the National Academy of Sciences. Researchers studied infants between 6- and 12-months old, looking at the purpose and timing of naps, using furry puppets to test the babies’ memories of their interactions with them and when napping took place. Babies who napped after encountering the puppets showed signs of recall 24 hours later more quickly than babies who did not nap right after the encounter.

NASA investigating ammonia alarm on space station: An alarm signaling a potential ammonia leak forced American astronauts on the International Space Station twice to seal themselves in the Russian portion of the orbiting science center. NASA assures that the crew is safe and that the U.S. portion of the station is clear of ammonia. The astronauts and crew on the ground are investigating the cause for the alarms and say there is no hard evidence of an ammonia leak.

NuSTAR captures image of black hole consuming gas from galaxy collision: A giant black hole gobbling up the remnants of a distant pair of colliding galaxies has been observed by NASA’s Nuclear Spectroscopic Telescope Array space telescope. An image released by NASA shows a black hole consuming gas and dust from the merging galaxies, known collectively as Arp 299. “We want to understand the mechanisms that trigger the black holes to turn on and start consuming the gas,” said NASA’s Andrew Ptak, lead researcher of the study, which has been accepted by the Astrophysical Journal for publication.

Study suggests zebra striping has to do with temperature: Zebras developed stripes to adapt to temperature changes in the climate, not to deter predators or pests, a study suggests. “In contrast to recent findings, we found no evidence that striping may have evolved to escape predators or avoid biting flies. Instead, we found that temperature successfully predicts a substantial amount of the stripe pattern variation observed in plains zebra,” the researchers write in a study published this week in the Royal Society Open Science. The scientists say they don’t yet know the cause of the temperature-stripe correlation.

Sulfate-eating microbe found in aquifer deep beneath ocean: An exotic microbe has been found in Earth’s undersea aquifer, according to researchers from the University of Southern California and the University of Hawaii. The new species of sulfate-eating microbe was discovered off the coast of Washington at the edge of the Juan de Fuca tectonic plate. “One of the surprises of this effort was the discovery of a microorganism that is unique and thriving in a place seemingly inhospitable to life,” said lead author Alberto Robador. The study was published in Frontiers in Microbiology.

Researchers identify hand ax crafted from bone in China: A hand ax crafted from bone, rather than stone, by ancient humans in what is now China has been identified by paleontologists at the China Three Gorges Museum in Chongqing. The tool was made from the lower part of a stegodon jaw and may have been used to dig out edible roots, according to the study published in Quaternary International. Researchers estimate the hand ax is about 170,000 years old.

Ancient scorpion species may have walked out of ocean on feet: A species of scorpion that most likely lived in water more than 430 million years ago has been discovered with feet that would have allowed it to venture onto land, suggesting the creatures emerged onto land earlier than previously thought. Eramoscorpius brucensis stands out from other ancient species of scorpion because “they could have walked on their feet, which is really important because it meant that they could have supported their own weight,” instead of being buoyed by water, said Janet Waddington, leader of the study published in Biology Letters.

First contracting human muscles grown by researchers: Duke University researchers have grown human skeletal muscle that contracts in response stimuli, which can be used to determine which drug would work best for each person. Increasing myogenic precursors, or cells that have yet to develop into muscle tissue, by more than 1,000 before being placed in 3D scaffolds led to the formation of myobundles that contract in response to electrical pulses. The study appeared in the journal eLife.

Renowned researchers pen letter to outline benefits, pitfalls of AI: Renowned scientists and technology leaders including Stephen Hawking and Elon Musk have issued a warning about the dangers of artificial intelligence. The group signed a letter that touts the many benefits of AI, and outlines the many risks. “Because of the great potential of AI, it is important to research how to reap its benefits while avoiding potential pitfalls. Our AI systems must do what we want them to do,” they said in the letter, published online by the Future of Life Institute.

Because we don’t need a real life Battlestar Galactica.

ESA’s lost Mars lander Beagle 2 spotted by NASA orbiter: NASA’s Mars Reconnaissance Orbiter has spotted the European Space Agency’s missing Beagle-2 lander, lost since it landed on the red planet on Christmas in 2003. “This finding makes the case that Beagle-2 was more of a success than we previously knew and undoubtedly an important step in Europe’s continuing exploration of Mars,” said David Parker, chief executive of the U.K. Space Agency. “These images are consistent with the Beagle-2 having successfully landed on Mars but then only partially deploying itself,” he said.

Study: Planets started forming before meteorites existed in early universe: Meteorites did not play a major role in the formation of the early universe, as previously thought, but instead were a byproduct of the event, according to a study published in Nature. Scientists ran computer simulations on the early formation of the solar system that showed that planets were already forming by the time meteorites began banging around creating chondrules, droplets of molten rock thought to be key in planet formation. “This tells us that meteorites aren’t actually representative of the material that formed planets — they’re these smaller fractions of material that are the byproduct of planet formation,” said author Brandon Johnson.

Ancient tool suggests Neanderthals were more advanced than once thought: An ancient bone tool found in France had many uses and dates back to the Neanderthal era, suggesting the closest ancestor of humans was more intelligent that previously thought. “It proves that Neanderthals were able to understand the mechanical properties of bone and knew how to use it to make tools, abilities usually attributed to our species, Homo sapiens,” said anthropologist Luc Doyon, an excavation participant.

Magnetic pull helps sea turtles return to their birth beaches, study suggests: Unique magnetic signatures help female sea turtles return to the beaches where they hatched to lay eggs, according to a study published in Current Biology. Researchers say magnetic particles found in sea turtles’ brains help them locate the unique magnetic signature of the beaches where they were born, helping them return there to nest after traveling the world’s oceans. “Our results provide evidence that turtles imprint on the unique magnetic field of their natal beach as hatchlings and then use this information to return as adults,” said J. Roger Brothers, co-author of the study.

Deeply submerged grounding zone in Antarctica may hold clues to glacial melting: Scientists have drilled deep into the grounding zone, a submerged area of Antarctica underneath the Ross Ice Shelf, hoping to find clues about the long-term stability of glaciers. What they found were pebbles sitting on top of sandy mud, which could indicate that the ice is melting more quickly. “From the looks of it, there’s been quite a change in the environment,” said glaciologist Ross Powell.

Additional planets may exist in solar system, study suggests: There may be at least two planets hiding beyond Neptune and dwarf-planet Pluto, according to a study of extreme trans-Neptunian objects, which circle the sun at huge distances in elliptical paths. “This excess of objects with unexpected orbital parameters makes us believe that some invisible forces are altering the distribution of the orbital elements of the ETNOs, and we consider that the most probable explanation is that other unknown planets exist beyond Neptune and Pluto,” said Carlos de la Fuente Marcos, lead author of a study published in the Monthly Notices of the Royal Astronomical Society Letters.

Awww, our little solar system family may be getting bigger soon!

After long journey, New Horizons starting to collect Pluto data: NASA’s New Horizons spacecraft has begun collecting data in its first science phase after a nearly 10-year journey to Pluto. Instruments aboard the craft started measuring dust and charged particles this week, and a long-range lens will start taking photos of the dwarf planet in a few days. New Horizons will get its closest view July 14, giving scientists the clearest view yet of Pluto.

Reptile fossils found in China a rare example of ancient parenting: An aquatic reptile from the Early Cretaceous period was caring for six offspring when they all died, a rare fossilized example of parental care, according to a study of the skeletons found on a farm in China. “Although it is possible that the individuals were all swept together during or soon after the event that killed them, it is [felt] that this specimen more likely represents an instance of postnatal parental care,” researchers wrote in the study published in Geosciences Journal. The fossils of the philydrosaurus and its young were donated in 2010 to the Jinzhou Museum of Paleontology.

DNA gives researchers new data on pair of extinct giant kangaroos: Scientists have extracted DNA from a pair of extinct giant kangaroos that died about 45,000 years ago. Short pieces of DNA were taken from a giant short-faced kangaroo and a giant wallaby, whose remains were found in a Tasmanian cave. “The ancient DNA reveals that extinct giant wallabies are very close relatives of large living kangaroos, such as the red and western grey kangaroos,” said Bastien Llamas, lead author of the study.

Evolution of the Color Blue: To compound the mystery, the colors red, black, and white are mentioned many times in the ancient manuscripts, and in the later one, like the bible and the Koran, green and yellow are mentioned as well. In fact, biblical Red is described in many of its hues (“argaman”-dark red, just like Homer’s sea, “shani”-pink, “siqrah”-deep red). And so is Green: olive green, grass green. but not a hint of blue.  So what gives?

On A Roll Again!

Happy Thursday, Aledan Merfolk! I’m happy to say that I’ve finally made it back into writer-brain, and I’ve finished just over half of Draft Three of StO this week! I’m currently writing a brand new Erie scene, and I’m really liking the changes I’ve made for her. She sounds more mature in this draft, and has actual goals beyond just doing whatever she can to survive (although that’s obviously goal #1). Finn’s still good ol’ Finnegan – he needed toning down on the misogynistic dickishness, but not a complete makeover like Erie did. The first half of the novel needed mostly characterization work, so now the real editing begins *cracks knuckles* Time to get out the axe and delete some scenes!

onelastsong_600x900I spent last night at a fancy dinner to celebrate SK Fall’s (re)release ONE LAST SONG, which is dark and twisty and I love it. We spent the night talking about writing and sex scenes and how amazing the food was at The Oridinary. I seriously ate so much I had a stomachache for a couple hours. A completely worth-it stomachache. There’s nothing better than good food and great conversation with best friends <3

If you missed it earlier this week, both Custom of the Week and Science Tuesday are back for the year. And I have the most amazing custom for you guy this weekend. It’s a seapony and I think you’ll love it just as much as I do!

And one last note, I’ve joined the new social-media site Tsu (because who doesn’t need more to keep up with?). There’s quite a nice little  writer community on there already, so if you want to check it out here’s an invite:

That’s it for this week, Aledans. Don’t forget to pick up your copy of ONE LAST SONG, and remember to stop by this weekend for the awesome seapony custom. Hopefully by the next update I’ll be nearly-done with this draft of StO! Have a great weekend!

Science Tuesday: Egyptian Queen Discovered, Black-hole Collision Course, and Beethoven’s Arrhythmic Compositions.

Happy Tuesday, Aledan Merfolk! Are you ready for 2015’s first dose of awesome science news? Let’s see what the new year has in store for us.

NASA works to fix aging rover’s memory problems: The rover Opportunity is starting to have memory problems after more than 10 years of exploring Mars, NASA scientists say, but researchers think they’ve found a way around the problem. Opportunity’s seventh bank of memory is having a problem, storing data instead in its random-access memory, which is wiped whenever the rover is switched off at night or rebooted. This can be a problem if it hasn’t sent the information to NASA’s Jet Propulsion Laboratory. Scientists plan to modify the rover’s software to think it only has six banks of flash memory, thereby skipping the troublesome seventh.

Study finds ancient coyotes sported larger jaws than modern cousins: Coyotes’ ancient ancestors had larger jaws than their modern cousins, allowing them to take down larger prey, according to a study published in PLOS ONE. Canis latrans likely dined on the young of large animals such as llamas, camels and horses as they roamed North America during the Pleistocene epoch, but the jaws began to shrink as prey size started getting smaller about 11,500 years ago and as the coyotes faced competition from larger predators.

Newly discovered frog species gives birth to tadpoles: A new fanged frog species has been identified in Indonesia, but what makes it unique is that its babies are born as tadpoles, skipping the egg process altogether, according to research published in PLOS ONE. The tiny Limnonectes larvaepartus is the only one of 6,455 species of frog known to give birth directly to tadpoles. “Reproduction in most frogs could not be more different from human reproduction. In this case, what is most interesting, ironically, is that the reproductive mode is more similar to our own,” said study author Jimmy McGuire, a herpetologist at the University of California at Berkeley.

Stem cells help researchers learn how dementia affects neurons: Through the use of stem cells, Belgian researchers have produced a sort of “dementia in a dish” to look into how the disorder develops and affects neurons. They found that induced pluripotent stem cells derived from skin cells of dementia patients were not able to generate cortical neurons, cells affected by frontotemporal dementia. The iPSCs have defective progranulin genes that alter the Wnt signaling pathway, which plays a vital role in neuronal development, researchers found. The study appeared in Stem Cell Reports.

Anglo-Saxon coins buried for 900 years found on U.K. farmland: A trove of near-mint-condition silver Anglo-Saxon coins buried for more than 900 years has been unearthed from farmland in Buckinghamshire, England. “This is one of the largest hoards of Anglo-Saxon coins ever found in Britain. When they have been properly identified and dated, we may be able to guess why such a great treasure was buried,” said a Bucks County Museum spokesman. If a coroner rules the $1.52 million coins are treasure under the Treasure Act, a museum will be able to purchase them, with the proceeds going to the farm owner and the Weekend Wanderers Detecting Club member who found the coins with a metal detector.

Tomb of previously unknown queen found in Egypt: The tomb of a previously unknown Fifth Dynasty queen has been found by archaeologists in Egypt in the funeral complex of Pharaoh Neferefre, who ruled 4,500 years ago. Archaeologists also found writings that identify her as Khentakawess III as well as reliefs on the tomb’s inner walls that say she is “the mother of the king” and “the wife of the king.”

Researchers use special heating chamber to learn about Venus: Scientists in Germany are using a super-hot heating chamber to help them learn more about the surface of Venus, which in mass and size is similar to Earth, but has surface temperatures that can melt lead. Researchers at the DLR Institute for Planetary Research in Berlin, using data collected about rocks on Venus, cooked basalt, anorthosite and hematite in a heating chamber that matched Venus’ scorching temperatures. The results suggest that Venus once had continents and oceans, researchers say.

Study: Fat cells produce antimicrobials to fight infections: Fat cells just beneath human skin may be the body’s first line of defense against bacterial infection and may also fight infections by producing antimicrobial compounds, according to a study published in Science. Researchers exposed mice to a staph bacteria resistant to antibiotics through a cut and found that the fat cells just under the wound site would thicken and produce cathelicidin, an antimicrobial compound, suggesting that the fat cells sensed the bacteria’s presence and reacted accordingly. “That was totally unexpected. It was not known that [fat cells] could produce antimicrobials,” said Richard Gallo of the University of California at San Diego and co-author of the study.

Event that spawned life on Earth was delayed due to volcanic iron, study finds: Subsea volcanoes on early Earth littered the oceans with a level of iron that poisoned oxygen-producing cyanobacteria, staving off the Great Oxidation Event by about half a billion years, according to research published in Nature Geoscience. Scientists at the University of Tubingen exposed modern-day microbes to the levels of iron found in ancient sediments, which caused the cyanobacteria to reduce the volume of oxygen they produced by up to 70%. The results help to explain the long period of time between the first appearance of cyanobacteria about 3 billion years ago and the Great Oxidation Event that spawned life about 2.5 billion years ago.

Massive alien planets might be home to ancient oceans, researchers say: Super-Earth planets may be home to long-lived oceans, according to findings presented at an American Astronomical Society meeting. Researchers used computer models to show how planets up to five times more massive than Earth could harbor ancient oceans, potentially allowing the development of life. “When people consider whether a planet is in the habitable zone, they think about its distance from the star and its temperature. However, they should also think about oceans, and look at super-Earths to find a good sailing or surfing destination,” said lead study author Laura Schaefer.

Greek palindrome inscribed on ancient amulet found in Cyprus: A 1,500-year-old double-sided amulet with a palindromic inscription was discovered in Cyprus. One side depicts several images, including a mummy in a boat, while the other side has an inscription that reads the same backward and forward in Greek. It translates to the non-palindromic, “Iahweh is the bearer of the secret name, the lion of Re secure in his shrine.”

New images of “Pillars of Creation” taken by Hubble telescope: The Hubble Space Telescope celebrated its 25th year in service by capturing a new image of the “Pillars of Creation,” about 7,000 light-years away from the sun in the Eagle Nebula. “It allows us to demonstrate how far Hubble has come in 25 years of observation,” said astronomer Paul Scowen, who was on the team 20 years ago when Hubble captured its first image of the Pillars. The latest image, taken with Hubble’s Wide Field Camera 3, which was installed in 2009, offers a sharper view of the Pillars’ glowing oxygen, hydrogen and sulfur.

Astronomers look ahead in search for Earth-like planets: NASA’s Kepler spacecraft has spotted eight new Earth-like planets in the “Goldilocks” habitable zone of the universe. As they join the hundreds of planets detected by Kepler, astronomers are speculating what to do next as they continue searching for worlds like our own. Scientists shared their findings and ideas at a meeting of the American Astronomical Society. Kepler will get some help in 2017 when the Transiting Exoplanet Survey Satellite is launched, tasked with finding Goldilocks planets closer to Earth.

June will be one second longer than usual: An extra second will be added to the clock just after 23:59:59 on June 30, according to Universal Time officials at the International Earth Rotation and Reference Systems Service. Leap seconds, introduced in 1972 to make up for Earth’s speed variations, are occasionally added either at the end of December or June to correct tiny desynchronizations between International Atomic Time, or the weighted average of some 200 atomic clocks around the world, and Universal Time, based on Earth’s rotation. The last time a leap second was added was at the end of June in 2012.

Fossil find could help determine if Utahraptors hunted in packs: A trove of dinosaur fossils found in a block of sandstone in Utah may help scientists determine if predatory dinosaurs known as Utahraptors hunted in packs or alone. The remains of at least six Utahraptors have been found together, along with those of an herbivore in the sandstone block that may at one time might have been quicksand during the Cretaceous period. “We believe it’s going to be the first example of dinosaurs trapped in quicksand en masse in the fossil record,” said Utah state paleontologist James Kirkland, who is leading the excavation effort.

Human enzyme CD39 shows promise against sepsis: A study in The Journal of the Federation of American Societies for Experimental Biology has found that the human membrane-bound enzyme CD39 acted against sepsis in an experiment on mice by clearing the bloodstream of high levels of adenosine triphosphate, leading to an improved survival rate. The enzyme also reduced organ damage, inflammation, immune cell apoptosis and bacterial load.

Time capsule placed by Samuel Adams, Paul Revere opened in Boston: Five newspapers, 23 coins, a George Washington medal, a colonial records replica and a silver plaque were taken this week from a time capsule placed underneath the Massachusetts State House’s cornerstone in 1795. The contents of the box were originally placed there by then-Gov. Samuel Adams and Revolutionary War figures Paul Revere and William Scollay, along with more items added in 1855 when the building’s foundation needed repairs.

Pair of black holes on collision course in remote galaxy, researchers say: A pair of supermassive black holes in a distant galaxy are on what appears to be a collision course, according to research published in Nature. Astronomers say the collision could occur about a million years from now, releasing a massive amount of energy into gravitational waves. The black holes circle each other at a range of about 180 billion miles, or about 290 billion kilometers, in the galaxy PG 1302-102, researchers say.

Early Chinese kingdom may have been devastated by rapid formation of desert: The rapid transformation from a verdant landscape to desert may have destroyed the first known kingdom in China about 4,200 years ago, according to a study published online in the Proceedings of the National Academy of Sciences. According to earlier research, Hongshan may have been the first-known Chinese kingdom, established about 6,500 years ago. Today scientists, who are trying to establish the importance of Hongshan, suggest that the rapid change in landscape devastated the Hongshan culture, spurring a move to the rest of China and influencing the rise of other civilizations.

New antibiotic shows promise in treating drug-resistant bacteria: An antibiotic isolated from New England dirt has successfully treated mice infected with drug-resistant staphylococci bacteria, which typically leads to death in 90% of the animals that contract it, according to a study in Nature. Teixobactin might be the first major drug breakthrough in more than 25 years, according to researchers, though it has yet to be tested on humans. “It should be used, if it gets successfully developed, as broadly as possible, because it is exceptionally well-protected from resistance development,” said NovoBiotic Pharmaceuticals co-founder Kim Lewis, a study author.

Pharaoh, gods depicted in wall relief found in Egyptian quarry: A wall relief depicting an unknown pharaoh and the gods Thoth and Amun-Ra has been found in a sandstone quarry in Egypt. Researchers are having trouble identifying the pharaoh because of the poor condition of the stela, which they suggest dates back to around the Third Intermediate Period between 1070 B.C. and 664 B.C. “The team is currently trying to retrieve more information, but the area of the figure and title of the pharaoh is eroded by wind and sand, not to mention a natural fracture in the rock,” said Gebel el Silsila Survey Project Director Maria Nilsson.

Study: Jupiter’s core eroding faster than previously thought: The rock and ice core of Jupiter may be eroding faster than previously thought, according to research by the RMIT University in Australia. Researcher Hugh Wilson used a quantum-mechanical model to ascertain how elements of Jupiter’s core spread out into the gas giant’s fluid outer layer and found that the disbursement occurred at twice the rate previously calculated. Wilson noted that when Juno, the spacecraft on its way to study Jupiter, arrives in 2016 it might find “a partially eroded husk of the planet’s original core.”

Bats improve chances of finding food by eavesdropping on each other: Bats eavesdrop on each other to improve their chances of finding prey, according to a study published in Current Biology. “When you sit in a dark cinema theater and someone opens a bag of chips, everyone in the theater knows that someone is eating chips and approximately where that someone is. Bats work similarly,” said Yossi Yovel, the lead researcher.

Researchers hear arrhythmia in Beethoven’s compositions: Scientists think the rhythms of Beethoven’s music may indicate an arrhythmia in the composer’s heartbeat, according to research published in Perspectives in Biology and Medicine. A cardiologist, a specialist in internal medicine and a musicologist joined forces to study Beethoven’s work as a “musical electrocardiogram,” noting distinctive rhythmic shifts that could be indicative of arrhythmia. “When your heart beats irregularly from heart disease, it does so in some predictable patterns. We think we hear some of those same patterns in his music,” said internal medicine specialist Joel Howell, a study co-author.

Researchers identify neurons responsible for proprioception, touch: Researchers have identified a group of neurons in the brain responsible for the sense of touch and proprioception. The discovery could lead to the development of prostheses that can receive tactile input and actively sense the surroundings. The findings were published in the journal Neuron.

SpaceX rocket launches Dragon cargo ship, but lands hard in return test: SpaceX’s Falcon 9 rocket launched Saturday from Cape Canaveral, Fla., sending its Dragon cargo ship on a supply run to the International Space Station, but had problems landing on an ocean platform in a test of the company’s plans to eventually return rockets to their launch sites. “Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time,” CEO Elon Musk wrote of the test on Twitter. He later said that the rocket ran out of hydraulic fluid, which it needed to maneuver its steerable fins, and that more fluid would be added for subsequent attempts.

Ancient fossils in Scotland belong to new species of marine reptile: Fossils found on Scotland’s Isle of Skye belong to a new species of marine reptile that lived around 170 million years ago, during the Jurassic period, researchers say. Dearcmhara fed on fish and other reptiles as it navigated the warm waters around Scotland, according to paleontologists who have studied fragments of skulls, vertebrae, teeth and an upper arm bone found on Skye over the past half-century. The findings are described in the Scottish Journal of Geology.

Getting Back to the Normal Routine

Happy Thursday, Aledan Merfolk! It’s a balmy 26F in Charleston today, which kind of makes me want to punch things. I didn’t move a thousand miles south to deal with this kind of weather! Of course, if I were back home in MI the wind chill would be below zero, so I guess I can’t complain too much. Poor Hubs comes home from a conference in Florida today, where he’s been enjoying warmer weather, and I can’t wait to see the look on his face when he gets out of the car ;)

I think I’ll spend the day in Key West with Finn and Erie to stay warm. I’m slowly getting back into my writer headspace by reading up to the point in Draft Three where I had to stop for the Holidays. Coming back to it with fresh eyes after a few weeks away was probably a good thing, and I’m pleased with the changes I’ve made so far. There’s still plenty to do, though, and I want to get it done by the end of the month.

Since things are getting back to normal around here, I’ll be posting the first Custom of the Week this Sunday, and Science Tuesdays will be back next week! I hope you have an awesome, productive and/or relaxing (whichever you need) weekend, Aledans!

Hops extremely muddy, and extremely happy to get back to the normal routine at the dog park.
Hops extremely muddy, and extremely happy to get back to the normal routine at the dog park.

Happy 2015!

Happy 2015 Aledan Merfolk! I’m back from my holiday hiatus with a new blog theme that’s as bright and cheerful as Erie the mermaid! After spending ten days in the car travelling to and around Michigan, Hubs and I are back home relaxing for the long weekend. We shook our fists at winter last night and had grilled hotdogs and potato salad – summer in January!

The long days on the road kept me brain-dead enough that I haven’t worked on any writing since mid-December, so I’ve mostly been playing Pharaoh on the laptop. I do plan to have the third draft of StO finished and off to CPs within the month, and I’m hoping to have something awesome to read from one of my CPs soon, so I’ll get back to the writer-brain asap.

After I beat this level of Pharaoh. I’ve restarted it four times already!

I hope you all had a wonderfully calm holiday season full of love and laughter. Any big plans for 2015? I’ll be here to cheer you on!

Holiday Hiatus

Happy Thanksgiving Eve, Aledan Merfolk! This is just a quick post to let you know I’ll be on a blogging hiatus for the rest of the year. I always forget how busy November and December are at work (who knew nuclear chemistry and retail had the same busy season?), so I need to focus all my energy on the dayjob and the next draft of StO. Three of my CPs sent their critiques back (within 24 hours of each other!) and they all said basically the same thing: StO’s narrative arc is solid, but I have a lot of characterization to work on. I already have a plan to re-write the first chapter, and plenty of changes to make in the middle, and I think this draft is going to be really solid.

I’ll see you next year, Aledan Merfolk, and I’ll have a new blog theme based on Erie! Have a safe and happy holiday season :)

#ScienceInSF Guest Post

Happy Wednesday, Aledan Merfolk! I’m happy to say I’m cruising along on the re-write/edit of the first four chapters of StO. The first chapter is finished, and I’m working on the horrible third chapter right now (third chapters are always my difficult chapters). The second and fourth chapters have their fixes plotted out and written on stickies. I hope to be finished by the end of the week, but that’ll depend on how this bar scene in the third chapter goes.

But that’s not really why I’m posting on a random Wednesday. I’m here to tell you Dan Koboldt invited me to write a guest post for his Science In SF series and it posted today! It’s all about Proper Lab Technique – if any part of your novel takes place in a laboratory, check it out and make sure you aren’t misusing a pipette in those scenes. Trust me, as a scientist reading your book things like that stick with you ;)

I didn’t have a chance to get Science Tuesday up yesterday, so I’ll be posting it tomorrow instead. All of Octobers best science news, all in one place on my blog!
