IKBFU Physicists have successfully tested the new magnetic micro wire-based concept of "smart" composites production. The new composites are related to the multiferroic-class materials which have mutually controlled magnetic and electric properties. The effects observed in the compositions are considered to be a perspective platform for creating new devices from energy converters to highly sensitive sensors.
A canine study carried out at the University of Helsinki has described a gene variant in the regulatory region of the retina resulting in the abnormal function of retinal genes and, eventually, in the loss of vision in dogs. The study can benefit the diagnostics and treatment of retinitis pigmentosa, a disease suffered by two million human beings globally.
Physicians who identify as "general practitioners" are a group distinct from board-certified "family physicians," according to a new study that was supported, in part, by the American Board of Family Medicine Foundation.
When faced with complex and difficult questions, such as how plants interact with their environment, sometimes the best approach is to bring together many different approaches. Three separate journals--the American Journal of Botany (AJB), Applications in Plant Sciences (APPS), and the International Journal of Plant Sciences (IJPS)--recently joined efforts to bring attention to these interactions from a variety of perspectives.
PRINCETON, N.J.--Five social scientists holed up in an Amsterdam hotel for a week with the goal of reaching a scientific consensus on how people form stereotypes. Remarkably, they were encouraged by the fact that none of them actually agreed with each other.
At a conference in Europe the year before, they had presented their conflicting theories. Those in the audience -- also social scientists -- wondered how they could comprehensively study stereotypes if they had to choose one model and reject the others.
Scientists from the RIKEN Cluster for Pioneering Research and RIKEN Center for Emergent Matter Science have succeeded, in collaboration with international partners, in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created a flexible organic cell that degrades by less than 5 percent over 3,000 hours in atmospheric conditions and that simultaneously has an energy conversion ratio--a key indicator of solar cell performance--of 13 percent.
In a recent study published in Marine Ecology Progress Series, researchers at California Polytechnic State University revealed that in addition to seasonal changes in winds and ocean temperatures, natural climate cycles greatly influenced the base of the food web at the Cal Poly Pier in San Luis Obispo Bay, an embayment located in Central California in the California Current Large Marine Ecosystem. Like seasons that drive recurring changes in ocean and atmospheric patterns every year, natural climate cycles drive rhythmic changes in these patterns over longer cycles.
Plastics are a victim of their own success, so inexpensive, easy to use and versatile that the world is awash in plastic waste. Now researchers from the University of Houston have reported a new method of producing polyolefins - made from hydrocarbons and the most common building block of plastics - structured to address one of the biggest stumbling blocks to plastics recycling.
The process also would allow plastics to be produced from food oils and other natural substances.
Turtle ant soldiers look like real-life creatures straight out of a Japanese anime film. These tree-dwelling insects scuttle to and fro sporting shiny, adorably oversized heads, which they use to block the entrances of their nests--essentially acting as living doors.
GAINESVILLE, Fla. --- Botanist Cody Coyotee Howard compares bulbs to living bunkers. With an underground stockpile of resources, bulbs can hunker down during disasters and spring up faster than other plants when conditions turn balmy.
The bigger the bulb, the more nutrients a plant has in times of need. But bulb size varies widely, even among related species, from the chive's barely-there below-ground organ to softball-sized yellow onions. Howard wondered why.
Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions. The enormous clouds emitting the light are Lyman-alpha blobs (LABs). LABs are several times larger than our Milky Way galaxy, yet were only discovered 20 years ago. An extremely powerful energy source is necessary to produce this radiation--think the energy output equivalent of billions of our sun--but scientists debate what that energy source could be.
What we learn through our senses drives how knowledge is sorted in our brains, according to research recently published in JNeurosci.
When we take a bite of an apple, we learn that "apples taste sweet" the same way we learn much of the information we know -- through a sensory experience. The brain stores such information in groups of neurons according to broad categories, like food and places. But, how does the brain store abstract knowledge that spans multiple categories, like "Granny Smith apples come from Australia"?

1. New branded PrEP not worth the high cost compared with generic formulation
PHOENIX -- A study by researchers at Mayo Clinic in Arizona published in the the Journal of Clinical Investigation has found that obesity is not only implicated in chronic diseases such as diabetes, but also in sudden-onset diseases such as pancreatitis.
Sea turtles around the world are threatened by marine plastic debris, mostly through ingestion and entanglement. Now, researchers reporting in the journal Current Biology on March 9 have new evidence to explain why all that plastic is so dangerous for the turtles: they mistake the scent of stinky plastic for food.
