A study analyses the selective attention processes that determine how we explore and interact with our environment — ScienceDaily

[ad_1] Researchers examined the visual response of 113 individuals when observing prehistoric ceramics belonging to different styles and societies. The ceramics analysed cover 4,000 years (from 4000 B.C. to the change of era) of Galician prehistory (north-west Iberia), and are representative of ceramic styles, such as bell-beaker pottery, found throughout Europe. The results indicate that…

New device perfectly controls the angle of reflection of sound waves — ScienceDaily

[ad_1] Researchers at Duke University and Aalto University (Finland) have constructed a “meta-mirror” device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror and only seeing the person next to you instead of your own face. The research appeared online on February 15 in…

50 is the new 40 for safe childbirth? — ScienceDaily

[ad_1] Ben-Gurion University of the Negev (BGU) and Soroka University Medical Center researchers have determined that it is as safe to give birth after age 50 as age 40 without endangering the mother or the baby. The paper was recently presented at the Society for Maternal and Fetal Medicine 39th Annual Pregnancy Meeting in Las…

New research illuminates some basic properties of these eccentric marvels of biology — ScienceDaily

[ad_1] University at Buffalo physicists are using innovative tools to study the properties of a bizarre class of molecules that may play a role in disease: proteins that cluster together to form spherical droplets inside human cells. The scientists’ latest research sheds light on the conditions that drive such droplets to switch from a fluid,…

Capturing 1.5 million frames per second could aid sports videography, movie production and scientific research — ScienceDaily

[ad_1] Researchers have developed a new imaging method that can capture images at speeds of up to 1.5 million frames per second using standard imaging sensors typically limited to 100 frames per second. This new technology will make it possible to capture extremely fast events for applications such as biomedical research or slow-motion scenes in…

Three ways studying organic chemistry changes the brain — ScienceDaily

[ad_1] Academic learning is about gaining new knowledge and skill, but only recently has it been possible to see new knowledge appear in a human brain. A new study from Carnegie Mellon University researchers using multiple imaging modalities shows that learning scientific information results in changes in the actual structure of memory-related areas of the…

Animal study links mutation of CD38 gene to major neurochemical dysfunctions found in autism — ScienceDaily

[ad_1] Oxytocin has been the focus of intense research around autism spectrum disorder (ASD) due to the hormone’s reported positive effects on anxiety, empathy, social interaction, and maternal behavior. ASD is characterized by early onset of behavioral and cognitive alterations, and by low plasma levels of oxytocin. The enzyme CD38 was recently demonstrated to be…

Pediatric onset multiple sclerosis study examines baffling, often-overlooked disease — ScienceDaily

[ad_1] Seemingly overnight, healthy children develop mysterious, potentially disabling symptoms. When children finally receive a diagnosis, often after weeks of tests and office and hospital visits, the parents may be shocked to learn that they have multiple sclerosis — a potentially disabling autoimmune disease once believed to affect only adults. “For many years, the tagline…

Surprise survival mechanism could lead to retooled drugs to treat infectious diseases — ScienceDaily

[ad_1] As bacteria continue to demonstrate powerful resilience to antibiotic treatments — posing a rising public health crisis involving a variety of infections — scientists continue to seek a better understanding of bacterial defenses against antibiotics in an effort to develop new treatments. Now, researchers at the University of California San Diego who combine experiments…

How does the body respond to diffuse cutaneous leishmaniasis? — ScienceDaily

[ad_1] In diffuse cutaneous leishmanisis (DCL), a rare form of leishmaniasis, parasites grow uncontrolled in skin lesions across the body. For the first time, researchers reporting in PLOS Neglected Tropical Diseases have now profiled how the human immune system responds to a DCL infection and, in turn, how Leishmania amazonensis adapts to the human host.…
