The cognitive roots of regularization in languageRegularization occurs when the output a learner produces is less variable than the linguistic data they observed.

Both of these factors modulate how

Anticipated synchronization in neuronal circuits unveiled by a phase-resetting curve analysisAnticipated synchronization (AS) is a counter intuitive behavior that has been observed in several systems.

New research points out that climate change will increase fire activity in Mediterranean EuropeIn the forthcoming decades, risks of summer fire may increase in Mediterranean Europe. A recent study, researchers show that the direct effect of climate change in regulating fuel moisture (droughts leading to larger fires) is expected to be dominant, regarding the indirect effect of antecedent climate on fuel load and structure -that is, warmer/drier conditions that determine fuel availability. T

Gene that causes rare disorder, Opitz C syndrome, identifiedOpitz C syndrome is a genetic disease that causes severe disabilities in patients and has been diagnosed in three people in the Iberian Peninsula, and sixty people in the world. A team of researchers has now identified a gene that causes the Opitz C syndrome in the only patient in Catalonia diagnosed with this severe congenital disease. This new scientific advance is a first step to discover the g

Sickle cell gene linked to elevated risk of developing kidney failureSickle cell trait, a common hemoglobin variant in African Americans, is associated with a twofold higher risk of developing kidney failure requiring dialysis, concludes a team of researchers. Sickle cell trait conferred a similar degree of risk as APOL1 gene variants, which are currently the most widely recognized genetic contributors to kidney disease in blacks.

Anxiety is a stronger harbinger of alcohol problems than stressStress and anxiety are widely believed to contribute to drinking. Alcohol is thought to reduce tension caused by stress (the “flight or fight” response) as well as alleviate the unpleasant symptoms of anxiety (anticipation of the unpredictable, impending threats). Prior research, however, has yielded inconsistent findings as to the unique relations between stress and anxiety, on the one hand, and

'Gloom' and doom when these insects are on hot, dry red maple treesThey are known as gloomy scales, and these insects can make a red maple tree’s life downright dreary. This is because the arthropods feed and thrive on them, especially in warm and dry urban landscapes.

New blood test may predict cardiovascular events in patients with or without coronary artery diseaseA new type of blood test may help physicians identify which patients with and without evidence of coronary blockages are at risk for heart attacks and strokes. Even individuals with normal levels of low-density lipoprotein (LDL), known as the so-called “bad” cholesterol, but still at risk, seem to be identified.

Research evaluates how financial criminals evade lawsTwo investigators examine the frequency and implications of bankruptcy fraud and money laundering. They also assess the degree of cultural and ethical differences between these acts in the United States and Europe, where the crimes are more prevalent.

What is innovation, and how can we awaken its dormant traits and cultivate them?While education may not be able to create innovative traits in individuals, education may improve the ability of individuals to utilize the traits they already possess. To that end, the authors begin by defining innovation and identifying the characteristics, traits, and thought processes of innovative individuals or groups of individuals and the environments that they exist in. The ultimate goal

Brain networks at rest are in readiness for action, researchers suggestBrain networks at rest appear to be waiting in a state of potentiation to execute even the simplest of behaviors, report researchers.

New Bedford Harbor identified as major source of airborne PCBsSediment contaminated with polychlorinated biphenyl, or PCBs, from the bottom of the New Bedford Harbor is the number one source of airborne PCBs in the neighborhoods surrounding the port, according to new research.

New NASA radar technique finds lost lunar spacecraftA new technological application of interplanetary radar has successfully located spacecraft orbiting the moon -- one active, and one dormant. This new technique could assist planners of future moon missions.

Cassini reveals strange shape of Saturn's moon PanNew images of Saturn's tiny moon, Pan, were taken on March 7, 2017, by NASA's Cassini spacecraft. These images are the closest images ever taken of Pan and will help to characterize its shape and geology.

NASA Mars Orbiter tracks back-to-back regional stormsA regional dust storm currently swelling on Mars follows unusually closely on one that blossomed less than two weeks earlier and is now dissipating, as seen in daily global weather monitoring by NASA's Mars Reconnaissance Orbiter.

NASA's Kepler provides another peek at ultra-cool neighborOn Feb. 22, astronomers announced that the ultra-cool dwarf star, TRAPPIST-1, hosts a total of seven Earth-size planets that are likely rocky, a discovery made by NASA's Spitzer Space Telescope in combination with ground-based telescopes. NASA's planet-hunting Kepler space telescope also has been observing this star since December 2016. Today these additional data about TRAPPIST-1 from Kepler are

Vicious circle of drought and forest loss in the AmazonLogging that happens today and potential future rainfall reductions in the Amazon could push the region into a vicious dieback circle. If dry seasons intensify with human-caused climate change, the risk for self-amplified forest loss would increase even more, an international team of scientists finds. If however there is a great variety of tree species in a forest patch, according to the study thi

Boaty McBoatface submersible prepares to dive into the abyss on first Antarctic missionBoaty McBoatface is joining ocean scientists on an expedition to study some of the deepest and coldest abyssal ocean waters on earth - known as Antarctic Bottom Water (AABW) - and how they affect climate change. The team of researchers will assess water flow and underwater turbulence in the Orkney Passage, a region of the Southern Ocean around 3,500m deep and roughly 500 miles from the Antarctic P
