Washington University in St. Louis — Fri, 02 May 2025 20:50:55 EST

WashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their movements and is key to male fertility. The discovery sheds light on why mammals, including humans, have evolved to keep male reproductive organs cooler than their core body temperature.

Copy Number Variant Analysis Improves Diagnostic Yield in a Diverse Pediatric Exome Sequencing Cohort

Children's Hospital Los Angeles — Fri, 02 May 2025 10:55:20 EST

Highlight:Exome sequencing (ES) is commonly used to diagnose Mendelian disorders, which occur when pathogenic variant(s) in a gene are either inherited from one or both parents or are de novo. Examples of such disorders include cystic fibrosis and sickle cell anemia. However, ES is not the first choice for detecting copy number variants (CNVs), which are typically deletions or duplications of DNA segments.

Explaining the Link Between 'Good' Gut Bacteria and Rheumatoid Arthritis

Ohio State University — Thu, 01 May 2025 19:40:07 EST

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.

Semiconductor Takes an Unconventional Path from Insulator to Metal

Department of Energy, Office of Science — Wed, 30 Apr 2025 19:20:14 EST

Scientists have discovered that Mn3Si2Te6 changes from an insulator to an electrically conductive metal when exposed to a magnetic field. In Mn3Si2Te6, applying a magnetic field causes a weak metallic state with trapped electrical changes to form in the material. This study examined the processes that cause this behavior.

'Scratching' More Than the Ocean's Surface to Map Global Microplastic Movement

Florida Atlantic University — Wed, 30 Apr 2025 19:05:12 EST

An international team of scientists has moved beyond just "scratching the surface," to understand how microplastics move through and impact the global ocean. For the first time, scientists have mapped microplastic distribution from the surface to the deep sea at a global scale - revealing not only where plastics accumulate, but how they infiltrate critical ocean systems.

Using Bacteria as Living Test Tubes to Study Human Gene Mutations and Find New Drug Leads

University of California San Diego — Wed, 30 Apr 2025 18:35:50 EST

Traditional methods of studying human gene mutations are often laborious and costly. Now bioengineers at UC San Diego have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.

Federal Tribe Uses Ancient DNA to Establish Genetic Link to Ancestral Sacred Sites

Southern Methodist University — Wed, 30 Apr 2025 11:00:00 EST

In a rare collaboration with geneticists and archaeologists, a federally recognized tribe in the United States has utilized ancient DNA to establish a genetic link to an important ancestral heritage site, Pueblo Bonito in Chaco Canyon.

Synchrotron in a Closet: Bringing Powerful 3DX-Ray Microscopy to Smaller Labs

Bar-Ilan University Evolutionary Analysis Reveals Protein Adaptations that Shield Mammals from Aging and Disease

Bar-Ilan University — Mon, 28 Apr 2025 07:25:53 EST

A recent study led by Prof. Haim Cohen at Bar-Ilan University, in collaboration with Dr. Sagi Snir and PhD student Sarit Feldman-Trabelsi, explores why some mammals live much longer and healthier lives than others.

Extreme Monsoon Changes Threaten the Bay of Bengal's Role as a Critical Food Source

Rutgers University-New Brunswick — Mon, 28 Apr 2025 05:00:00 EST

New research involving Rutgers professors has revealed that expected, extreme changes in India's summer monsoon could drastically hamper the Bay of Bengal's ability to support a crucial element of the region's food supply: marine life. The study, published in Nature Geoscience, was conducted by scientists from Rutgers University, the University of Arizona and collaborators from India, China and Europe. To reach their conclusions, the scientists examined how the monsoon, which brings heavy rains to the Indian subcontinent, has influenced the Bay of Bengal's marine productivity over the past 22,000 years.

More Power Grid Connectivity in Western U.S Could Supercharge Clean Energy
