Americans have long believed that sports are one area in society that offers kids from all backgrounds the chance to succeed to the best of their abilities. But new research suggests that this belief is largely a myth, and that success in high school and college athletics often is influenced by race and gender, as well as socioeconomic status, including family wealth and education.

Adverse genetic mutations can cause harm and are due to various circumstances. 'Jumping genes' are one cause of mutations, but cells try and combat them with a specialized RNA called piRNA. Researchers have identified how the sites responsible for piRNA production evolve effective behaviors against jumping genes. This research could lead to downstream diagnostic or therapeutic applications. Read more ›

Though we learn so much during our first years of life, we can't, as adults, remember specific events from that time. Researchers have long believed we don't hold onto these experiences because the part of the brain responsible for saving memories -- the hippocampus -- is still developing well into adolescence and just can't encode memories in our earliest years. But new research finds evidence that's not the case. In... Read more ›

A new study documents Putah Creek-origin salmon, meaning some salmon returning to the restored creek in the fall to spawn were actually born there. The study carries broader implications for other degraded streams and wild salmon runs. Read more ›

Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE) have uncovered a key role of a molecular signalling pathway (the Shh pathway) in their formation. This research provides new insights into the morphogenetic mechanisms that led to feather diversification throughout evolution. Read more ›

To understand why kangaroos hop -- a rarity among animals -- researchers have studied the musky rat-kangaroo (Hypsiprymnodon moschatus), a diminutive marsupial that weighs only 500 grams but is the last living representative of its family and part of a lineage that extends back to before kangaroos evolved their distinctive hopping gait.

An experimental drug appears to reduce the risk of Alzheimer's-related dementia in people destined to develop the disease in their 30s, 40s or 50s, according to the results of a new study. The findings suggest -- for the first time in a clinical trial -- that early treatment to remove amyloid plaques from the brain many years before symptoms arise can delay the onset of Alzheimer's dementia.

In the desert areas of Namibia, Oman, and Saudi Arabia, research work has revealed unusual structures that are probably due to the activity of an unknown microbiological life form. Unusually small burrows, i.e., tiny tubes that run through the rock in a parallel arrangement from top to bottom, were discovered in marble and limestone of these desert regions. Read more ›

For adolescents struggling with substance abuse, traditional in-person interventions such as counseling are not always effective, and rural areas often lack access to these services. A researcher is thinking outside the box, aiming to help game designers develop fun, digital games that make ditching bad habits easier by meeting adolescents where they already are: online.

A novel porous material capable of separating deuterium (D2) from hydrogen (H2) at a temperature of 120 K has been introduced. Notably, this temperature exceeds the liquefaction point of natural gas, thus facilitating large-scale industrial applications. This advancement presents an attractive pathway for the economical production of D2 by leveraging the existing infrastructure of liquefied natural gas (LNG) production pipelines. Read more ›
