Several years ago, an international team of scientists raised sediments from the bottom of Lake Van in eastern Turkey reflecting the past 600,000 years. Soil scientists and paleobotanists have now evaluated the drill cores for residues of early... more
How are the images cast on the retina reassembled in the brain? Researchers have found that processing of visual stimuli occurs at the earliest waystation on the way to the... more
New research provides direct evidence that we can take others' perspectives because we spontaneously form mental images of how the world looks to the other person, so that we can virtually see through their eyes and make judgements as if... more
Researchers swabbed more than 2300 animals representing 205 amphibian species to better understand the ecology of their skin bacteria. They asked which environmental factors... more
Patients with interstitial lung disease—a group of disorders causing progressive scarring of lung tissue—are often prescribed various medications that specifically... more
Is the current American drug overdose epidemic an isolated phenomenon? Have other high-income countries experienced similar increases in drug overdose mortality, or... more

Many situations in economics are complicated and competitive. New research raises the question of whether many theories in economics may suffer from the very fundamental problem... more
Capsicum is a major vegetable and spice crop worldwide. Global production of both fresh and dried fruit continues to increase steadily in terms of area harvested and total yield. A comprehensive review... more
Patients with Duchenne muscular dystrophy (DMD) have few treatment options. Medications currently available or in development either target only a... more
Researchers from the University of Neuchâtel, Switzerland have developed an ultra-sensitive method to quantify extremely low concentrations of neonicotinoid pesticides in honey. more
There is currently not enough evidence related to the effects of noncaloric sweeteners on appetite, short‑term intake, and risk of suffering from cancer or diabetes, as... more
Paleobiologists have shed new light on a jaw-snapping species of prehistoric worm using half-a-billion-year-old fossils kept at the Smithsonian Institute in Washington,... more
Counties in the United States with greater gaps between rich and poor have a higher rate of homicide deaths involving firearms, according to a new study.... more
Nitrogen fixation is surprisingly high in the ocean's coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows. The findings -- based on thousands... more
Using high-throughput genetic sequencing methods, scientists have created the first cellular atlas of the primate retina, an important foundation for researchers to build on as they seek to understand how vision works in primates, including humans, and how vision can... more
Algorithm and software system Shenango improves data center efficiency for microsecond-speed operations by better allocating data processing across CPU cores to reduce tail latency and ensure hardware runs productively. more
Researchers have discovered a surprising new source of carbon dioxide emissions -- bicarbonates hidden in the lake water used to irrigate local orchards. more
Researchers have discovered how blood vessels protect the brain during inflammation -- a finding that could lead to the development of new treatments for neurodegenerative diseases such as stroke, epilepsy and multiple... more
Asthma risk factors include smoking, dust mites, and environmental pollutants, as well as many others. Steering clear of these risk factors can help people avoid developing the condition.... more
Triclosan exposure may inadvertently drive bacteria into a state in which they are able to tolerate normally lethal concentrations of antibiotics -- including those antibiotics that are commonly... more
A new study outlines more than a decade of success in reducing seabird bycatch in Alaska's longline fisheries, and where there's still room for improvement. more
In the United States, the removal of dams now outpaces the construction of new ones -- with more than 1,400 dams decommissioned since the 1970s -- and a new study suggests that... more
