Weighing just 8-10 grams each, Golden-winged Warblers (Vermivora chrysoptera) are the smallest birds yet to be outfitted with geolocators. The researchers captured 20 Golden-winged Warblers at each of two sites, one in Minnesota and one in Tennessee, in May 2013 and fitted them with geolocators using their new method. When the warblers returned to the following spring after having traveled over five thousand miles, geolocator-carrying birds did not differ significantly from control birds in return rate, migration timing, or body mass.

The groups developed a stand-alone, nanowire array that captures light and with the help of bacteria, converts carbon dioxide into acetate. The bacteria directly interact with light-absorbing materials, which the researchers say is the first example of "microbial photoelectrosynthesis." Another kind of bacteria then transforms the acetate into chemical precursors that can be used to make a wide range of everyday products from antibiotics to paints.
The global industrial sector accounts for more than half of the total energy used every year. Now scientists are inventing a new artificial photosynthetic system that could one day reduce industry's dependence on fossil fuel-derived energy by powering part of the sector with solar energy and bacteria. In the ACS journal Nano Letters, they describe a novel system that converts light and carbon dioxide into building blocks for plastics, pharmaceuti...

Individuals who appear very different from most others in a group will evolve to be altruistic towards similar partners, and only slightly spiteful to those who are dissimilar to them. However, individuals who appear very similar to the rest of a group will evolve to be only slightly altruistic to similar partners but very spiteful to dissimilar individuals, often going to extreme lengths to hurt them.

Taken together, individuals with 'common' and 'rare' appearances may treat each other very differently. This finding is a new twist on established evolutionary theory and could help explain racism and corresponding forms of prejudice in humans and other species.
DB Krupp and Peter Taylor offer twist on evolutionary theory which could help explain racism and other forms of prejudice.

The researchers created a stretchable and transparent wearable sensor by layering a carbon nanotube film on two different kinds of electrically conductive elastomers. They found it could tell whether subjects were laughing or crying and where they were looking. In addition to applications in robotics, the sensors could be used to monitor heartbeats, breathing, dysphagia (difficulty swallowing) and other health-related cues.
Most people are naturally adept at reading facial expressions -- from smiling and frowning to brow-furrowing and eye-rolling -- to tell what others are feeling. Now scientists have developed ultra-sensitive, wearable sensors that can do the same thing. Their technology, reported in the journal ACS Nano, could help robot developers make their machines more human.

The most commonly reported triggers for FARS were the sound of crinkling tin foil (82 cats), a metal spoon clanging in a ceramic feeding bowl (79 cats), chinking or tapping of glass (72 cats), crinkling of paper or plastic bags (71 cats), tapping on a computer keyboard or clicking of a mouse (61), clinking of coins or keys (59), hammering of a nail (38) and even the clicking of an owner's tongue (24). Other, less common triggers were the sound of breaking the tin foil from packaging, mobile phone texting and ringing, digital alarms, Velcro, stove igniting ticks, running water, a dog jangling its collar as it scratched, computer printer, firewood splitting, wooden blocks being knocked together, walking across a wooden floor with bare feet or squeaky shoes and, in one case, the short, sharp scream of a young child.

Now we just need to figure out why pulling stickytape off the roll makes them poke their tongue out.
When the charity International Cat Care asked veterinary neurologists at Davies Veterinary Specialists, UK, for help with several enquiries it had received regarding cats having seizures, seemingly in response to certain high-pitched sounds, the answer was that the problem was not documented and little, if anything, was known about it.

The technique enables the reconstructed floating 3D object to be vividly and naturally viewed in a wide angle up to 52 degrees.
The smaller the refractive index pixels, the larger the bending angle once the beam passes through the hologram. This nanometer size of pixels is of great significance for the reconstructed 3D object to be vividly viewed in a wide angle.

The process is complex but the key physical step is to control the heating of photoreduction of graphene oxides, derivatives of graphene with analogous physical structures but presence of additional oxygen groups.
Through a photoreduction process, without involving any temperature increment, graphene oxides can be reduced toward graphene by absorbing a single femtosecond pulsed laser beam.
During the photoreduction, a change in the refractive index can be created. Through such a photoreduction we are able to create holographically-correlated refractive index pixel at the nanometer scale.

The paper was published today in Nature Communications: http://www.nature.com/ncomms/2015/150422/ncomms7984/full/ncomms7984.html

Finally, the origin of Japanese tentacle porn.
The last common bilaterian ancestor was a complicated coelomic creature and had both appendages for movement and food collection and a complex nervous system. According to this view the coelom in different groups underwent reduction for various reasons related to the peculiarities of development, anatomy, and lifestyle.
Researcher from the Lomonosov Moscow State University discovered new insights into the appearance of the humans' common ancestor. It will help to construct a natural system of the animal kingdom, through which the classification of species will become more specific.

Meet Yi qi, Mandarin for “strange wing” (pronounced “yee chee”).

The transition from dinosaur to bird wasn’t as straight forward as previously thought. A great deal of innovation took place in animals close to the origin of birds, ranging from the membranous wings of Yi to the four feathery wings of Microraptor.

One objection against the dinosaurian origin of birds was the supposed absence of feathered dinosaurs in rocks older than Archaeopteryx (the 150 million year old “first bird”). The Daohugou removes this paradox, revealing a community of feathered creatures that lived over 10 million years before Archaeopteryx.

Flight evolved multiple times within the dinosaurs. The configuration in modern birds, with a single pair of feathered wings, would ultimately prove to be the winning formula.
The discovery of a new winged dinosaur from more than 160 million years ago shows how they experimented with different forms of flight.

Medical Science  - 
 
For years, scientists have been searching for a way to convert types A and B into type O. They found that some enzymes from bacteria can clip the sugars off red blood cells that give blood its "type." But the enzymes are not very efficient. The researchers tweaked one of those enzymes and improved its ability to remove type-determining sugars by 170-fold, rendering it antigen-neutral and more likely to be accepted by patients regardless of their blood type.

In addition to blood transfusions, the researchers say their advance could potentially allow organ and tissue transplants from donors that would otherwise be mismatched.
Every day, thousands of people need donated blood. But only blood without A- or B-type antigens, such as type O, can be given to all of those in need, and it's usually in short supply. Now scientists are making strides toward fixing the situation. In ACS' Journal of the American Chemical Society, they report an efficient way to transform A and B blood into a neutral type that can be given to any patient.

The MESSENGER flybys of Mercury in 2008 and 2009 were able to confirm the earlier Mariner 10 results that Mercury had an internal magnetic field and also to show that its magnetic dipole – which is just like a large bar magnet – is aligned to within 5° of the planet’s spin axis.

In an early flyby in 2008 there was a totally unexpected discovery that there were large amounts of water present in Mercury’s thin atmosphere. Visual evidence of past volcanic activity on the surface of Mercury and evidence for a liquid iron planetary core added to the incredible discoveries.

in November 2012, NASA announced, evidence of water ice and carbon-containing tar-like organic compounds molecules at both of Mercury’s poles. In these areas the deepest parts of the craters are always in shadow with temperatures reaching as low as -200C.
This discovery lends weight to the idea that Mercury, like the Earth, was bombarded by water-laden comets and mineral rich asteroids during the early years of the solar system.

A second extended mission was scheduled to last through to March this year and has taken advantage of the probe’s orbital decay to obtain highly detailed close-up photographs of ice-filled craters and other landforms at Mercury’s north pole.

And so after a mission lasting almost 11 years the tiny robotic probe MESSENGER will end its mission on 30 April by crashing into the surface of the planet. Even then data will be gathered: the new man made crater the probe crash makes will hopefully provide new information for the NASA scientists. On its final orbit the probe will be only around 250 - 500 m above the surface at around 14,500km/hr.
NASA scientists will continue to gather data from MESSENGER until it finally succumbs to Mercury’s gravity.
It was the first probe to find water on Mercury, the planet closest to the sun. Its mission nearly over, MESSENGER is about to crash into the planet it's been observing.

With leadership in the show Transformers, there's more than meets the eye.
Peter Harms, an assistant professor of management at the University of Nebraska-Lincoln, and his frequent collaborator, Seth Spain of Binghamton University, rated the leadership skills of more than 120 characters featured in 'The Transformers' cartoon in 1984-85 and 'The Transformers: The Movie' in 1986. Their findings have implications for today's workplaces, since many leaders grew up watching those cartoons.

Some individuals had wide plates, some had tall, with the wide plates being up to 45 per cent larger overall than the tall plates. According to the new study, the tall-plated Stegosaurus and the wide-plate Stegosaurus were not two distinct species, nor were they individuals of different age: they were actually males and females.
Stegosaurs' plates may have differed between males and females.
