The stress-induced mechanisms that cause our brain to produce feelings of fear in the absence of threats -- such as in PTSD -- have been mostly a mystery. Now, neurobiologists have identified the changes in brain biochemistry and mapped the neural circuitry that cause generalized fear experiences. Read more ›

A recent study links the FRYL gene to a new neurodevelopmental disorder in humans. They used fruit flies to establish that the loss of a functional copy of the FRY-like transcription coactivator (FRYL) gene is the underlying cause of this new disorder in fourteen individuals. Read more ›

We are all aware of the dangers of pollution to our air, water, and earth. In a recently published letter, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload. Read more ›

Early childhood is an important time for learning about nutrition and establishing healthy eating behaviors. Young children rely on parents to provide food options, and the availability of food in the home affects their dietary choices. A new study looks at changes in home food availability and nutrient intake for children from 2 to 4 years old. Read more ›

A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. Until now, the biological mechanism of this protection was not well understood. Read more ›

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine. Read more ›

A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability... Read more ›

Researchers investigated the propulsion mechanism by visualizing water flow around a swimmer during underwater dolphin-kick swimming in a water channel via particle image velocimetry. Their findings revealed that swimmers can utilize water flow and vortexes more effectively as their speed increases. Read more ›

Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a new study.

After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods. Read more ›

Researchers have discovered that some fish -- unlike humans -- do not need orexin to stay awake. This molecule was thought to be necessary for normal wake and sleep rhythms in vertebrates. Humans without orexin suffer from narcolepsy. Read more ›

Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes. Read more ›

It is known that large amounts of licorice cause high blood pressure. A new study now shows that even small amounts of licorice raise blood pressure. The individuals who react most strongly also show signs of strain on the heart. Read more ›

A recent study observing wild chimpanzees over a period of more than 10 years revealed that when food gets scarcer, the adults put play aside and focus on survival, while mother chimps continue to be their children's primary playmate -- suggesting their indispensable role to foster their young's physical and social development.
