Nature greets a new one-atom-thick material – a super-thin sheet of tin scientists at Shanghai Jiao Tong University are calling “stanene”: Stanene (from the Latin stannum meaning tin, which also gives the element its chemical symbol, Sn), is the latest cousin of graphene, the honeycomb lattice of carbon atoms that has spurred thousands of studies into related 2D materials. Those include sheets of silicene, made from silicon atoms; phosphorene, made from phosphorus; germanene, from germanium; and thin stacks of sheets that combine different kinds of chemical elements…. Many of these sheets are excellent conductors of electricity, but stanene is — in theory — extra-special. At room temperature, electrons should be able to travel along the edges of the mesh without colliding with other electrons and atoms as they do in most materials. This should allow the film to conduct electricity without losing energy as waste heat, according to predictions2 made in 2013 by Shou-Cheng Zhang, […]
The New Horizons Long Range Reconnaissance Imager (LORRI) snapped this photo of Jupiter’s ring system on February 24, 2007, from a distance of 7.1 million kilometers (4.4 million miles).
This processed image shows a narrow ring, about 1,000 kilometers (600 miles) wide, with a fainter sheet of material inside it. The faint glow extending in from the ring is likely caused by fine dust that diffuses in toward Jupiter. This is the outer tip of the “halo,” a cloud of dust …

Three names for one little fish. And those are just the beginning.
I found this one on the Scientific Illustration tumblog, which quoted Wikipedia on the doree (etc.):
John Dory, St Pierre or Peter’s Fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible benthic coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an ‘evil ey…
These are ostensibly Cochin chickens, or forerunners of what we’d call Cochins today. They’re a breed with a *lot* of character, and are uniquely suited, temperamentally, for being “pet” chickens moreso than egg factories or walking meat supplies. Despite the name (after a part of India), they’re originally from China.
It’s the most Earth-like planet yet discovered. Kepler 452b sits in the “Goldilocks” zone around its star, not too hot and not too cold, and is about the same size (or is a little larger) and made of something like the same stuff as the planet we’re sitting around on right now. It takes 365 days to orbit around its sun, too. NASA’s calling it ou…

Click to embiggen Apparently, since last December at least, NASA has been creating vintage-style travel posters for exoplanets – the planets we’ve been discovering around faraway stars. This one, HD 40307g, is eight times Earth’s mass, and might be either a really large rocky planet (like Earth) or a really small ice giant (like Neptune). Either way, base jumping would definitely be different there. There are quite a few other potential destinations at the Exoplanet Travel Bureau, all of which have their own unique charms.
Science Daily processes a University of Haifa finding about why first impressions are so important – and how *feeling* a thing helps you *know* a thing: Dr. Shlomo Wagner of the Sagol Department of Neurobiology at the University of Haifa, who undertook the study, explains: “It turns out that different emotions cause the brain to work differently and on distinct frequencies.” The main goal of the new study, which was published this February in the science journal eLife, was to identify the electrical activity that takes place in the brain during the formation of social memory. During the course of their work, the researchers — Dr. Wagner and Ph.D. Alex Tendler — discovered the scientific explanation behind the saying “you never get a second chance to make a first impression.” … In the first part of the study the researchers examined the electrical activity in the brains of rats during social behavior. They discovered strong […]
Quartz opens a window on the two periods of brain development when traumatic events do the most damage: According to Tara Swart, a neuroscientist and senior lecturer at MIT, your “terrible twos” and those turbulent teen years are when the brain’s wiring is most malleable. … “We start to understand speech first, then we start to articulate speech ourselves and that’s a really complex thing that goes on in the brain,” Swart, who conducts ongoing research on the brain and how it affects how we become leaders, told Quartz. “Additionally, children start to walk — so from a physical point of view, that’s also a huge achievement for the brain. Learning and understanding a new language forces your brain to work in new ways, connecting neurons and forming new pathways. This is a mentally taxing process, which is why learning a new language or musical instrument often feels exhausting. With so many important changes happening […]
OK, I’m overstating things for dramatic effect… but another Science Daily report reveals even moderately picky eaters face health risks: According to the study, published August 3 in the journal Pediatrics, more than 20 percent of children ages 2 to 6 are selective eaters. Of them, nearly 18 percent were classified as moderately picky. The remaining children, about 3 percent, were classified as severely selective — so restrictive in their food intake that it limited their ability to eat with others. “The question for many parents and physicians is: when is picky eating truly a problem?” said lead author Nancy Zucker, Ph.D., director of the Duke Center for Eating Disorders. “The children we’re talking about are not just misbehaving kids who refuse to eat their broccoli.” Children with both moderate and severe selective eating habits showed symptoms of anxiety and other mental conditions. The study also found that children with selective eating behaviors were nearly […]
Science Daily reveals that parents are (as we suspected) getting it all wrong – they think their 10-year-olds are happier – and their 15-year-olds are unhappier – than they really are: The study was conducted by Dr Belén López-Pérez, Postdoctoral Research Fellow in Developmental and Social Psychology at Plymouth University, and Ellie Wilson, a recent graduate of the BSc (Hons) Psychology course. They questioned a total of 357 children and adolescents from two different schools in Spain, along with their parents, and their happiness was assessed using a range of self-reporting measures and ratings. The results showed that parents were inclined to score a child or adolescents’ happiness closely in line with their own emotional feelings, whereas in fact there were notable differences in the child’s own reports. In this regard, children and adolescents reported very similar levels of happiness, however parents also reported different levels depending on the age of their child. Thus, the […]
Not sure how it smells once you rub it on (despite assurances it doesn’t), but New Scientist is looking toward a blend of fish extract and shrimp shells to protect our skin and more against UV exposure: Some species of algae, bacteria and fish that spend a lot of time in the sun have evolved sun shields that absorb the DNA-damaging UV rays in sunlight. These chemicals, known as Mycosporine-like amino acids, have now been turned into a material that can be applied like a sunscreen to skin, as well as objects such as outdoor furniture that are at risk of UV damage. Besides potentially being a more effective UV-absorber than conventional sunscreens, this natural alternative is biodegradable and some of its ingredients could be scavenged from food waste. Vincent Bulone from AlbaNova University Center in Stockholm, Sweden, and colleagues from the University of the Basque Country in Leioa, Spain, reacted the amino acids with […]
As a species. In some pretty profound ways, Nature says. They highlight a few of the “outsize effects” our Neanderthal genes have on our lives: Now researchers are using large genomics studies to unravel the decidedly mixed contributions that these ancient romps made to human biology — from the ability of H. sapiens to cope with environments outside Africa, to the tendency of modern humans to get asthma, skin diseases and maybe even depression. … In some cases, they are very different from the corresponding H. sapiens DNA, notes population geneticist David Reich of Harvard Medical School in Boston, Massachusetts — which makes it more likely that they could introduce useful traits. “Even though it’s only a couple or a few per cent of ancestry, that ancestry was sufficiently distant that it punched above its weight,” he says. … Using de-identified genome data and medical records from 28,000 hospital patients, [Corinne Simonti and Tony Capra, […]
Sky News looks up to report on NASA’s airiest plans for exploring Jupiter. They’re designing a flock of turbulence-fueled “windbots” – cheap, floating robots to map out the gas giant: The idea is for the devices to stay aloft by relying on turbulence from a planet’s atmosphere, and the concept is now being developed by space programme scientists. NASA described the windbots concept as “a new class of robotic probe designed to stay aloft in a planet’s atmosphere for a long time without wings or hot-air balloons.” Differences in wind velocity and strength would allow the windbots to boost their energy. NASA jet propulsion expert Adrian Stoica said: “It’s a spring of energy a probe could drink from.” — The concept is modeled on dandelion seeds. The machines, though, look like 20-sided dice.
Wired revels in the newest scientific revolution – the ability to rewrite our genes with ease: The stakes, however, have changed. Everyone at the Napa meeting had access to a gene-editing technique called Crispr-Cas9. The first term is an acronym for “clustered regularly interspaced short palindromic repeats,” a description of the genetic basis of the method; Cas9 is the name of a protein that makes it work. Technical details aside, Crispr-Cas9 makes it easy, cheap, and fast to move genes around—any genes, in any living thing, from bacteria to people. “These are monumental moments in the history of biomedical research,” Baltimore says. “They don’t happen every day.” Using the three-year-old technique, researchers have already reversed mutations that cause blindness, stopped cancer cells from multiplying, and made cells impervious to the virus that causes AIDS. Agronomists have rendered wheat invulnerable to killer fungi like powdery mildew, hinting at engineered staple crops that can feed a population […]
Nature has more on the Brazilian “hugging” snake with legs… that’s changing the way we look at reptile origins: Although it has four legs, Tetrapodophis amplectus has other features that clearly mark it as a snake, says Nick Longrich, a palaeontologist at the University of Bath, UK, and one of the authors of a paper describing the animal in Science1. The creature’s limbs were probably not used for locomotion, the researchers say, but rather for grasping prey, or perhaps for holding on to mating partners. Such speculation inspired the snake’s name, which loosely translates as ‘four-legged hugging snake’. … “I was confident it might be a snake,” says David Martill, a palaeobiologist at the University of Portsmouth, UK, who came across the find in 2012. “It was only after getting the specimen under the microscope and looking at it in detail that my confidence grew. We had gone to see Archaeopteryx, the missing link between […]
Click to embiggen This is an artist’s impression of a planet just discovered by NASA’s Kepler mission that’s gotten the folks at SETI all excited. It’s the most Earth-like planet yet discovered. Kepler 452b sits in the “Goldilocks” zone around its star, not too hot and not too cold, and is about the same size (or is a little larger) and made of something like the same stuff as the planet we’re sitting around on right now. It takes 365 days to orbit around its sun, too. NASA’s calling it our “bigger, older cousin”. There are a couple of other, smaller and more Earth-like, planets in the new Kepler findings, too. No one’s saying there’s water on any of them, or little aliens hanging out at the beach. But there’s no reason why there wouldn’t be, either. [via Mr. Finfrock]
