Saturated fatty acid levels increase when making memories

Newly-available scientific evidence, which could prove critical to the success of climate-related lawsuits, is often not produced in court, according to a new study published today by the Oxford Sustainable Law Programme and Environmental Change Institute. Filling the evidentiary gap in climate litigation in Nature Climate Change, a leading interdisciplinary science journal, is the first global study on the use and interpretation of climate-science evidence in lawsuits. The study reveals evidence submitted by litigants in 73 lawsuits across 14 jurisdictions is significantly behind state-of-the-art ...

(Boston)--Amyloid diseases, including Alzheimer's, Parkinson's, type-2 diabetes and other life-threatening diseases, involve pathologic deposits of normally soluble proteins or peptides as insoluble amyloid fibrils. When this happens in vital organs, such as the brain, kidney, liver and heart, it causes organ damage and, if left untreated, death. Unfortunately, the available treatment options are very limited. Now a new study from researchers at Boston University School of Medicine (BUSM) improves our understanding of how heparan sulfate and related biopolymers such as heparin, which is perhaps best known as a blood thinner, can promote amyloid deposition in various organs. The researchers ...

(COLUMBUS, Ohio) - While little research exists on how and why the rates of Black youth suicide are rising, research does show the rate of suicide in Black youth younger than 13 years of age is approximately two times higher compared to white peers. From 2009 to 2019, the percentages of Black youth who considered suicide, made a suicide plan and attempted suicide all increased. In a statement published in JAMA Pediatrics, researchers at the Nationwide Children's Hospital, the University of North Carolina at Chapel Hill and the nonprofit research institute RTI International ...

A gene variant that lowers white blood cell levels and is common in individuals with African ancestry contributes to unnecessary bone marrow biopsies, according to a study published June 28 in JAMA Internal Medicine. The findings from three institutions, led by investigators at Vanderbilt University Medical Center, provide an example of how using genetic data could reduce a health disparity. "We've essentially created this racial health disparity by not fully considering how genetic variation affects white blood cell levels," said Jonathan Mosley, MD, PhD, assistant professor of Medicine and Biomedical Informatics at VUMC. "Our study supports genotyping African Americans before ...

Most people associate the term "wearable" with a fitness tracker, smartwatch, or wireless earbuds. But what if you could wear cutting-edge biotechnology in your clothing, and it could warn you when you were exposed to something dangerous? A team of researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Massachusetts Institute of Technology has found a way to embed synthetic biology reactions into fabrics, creating wearable biosensors that can be customized to detect pathogens and toxins and alert the wearer. The team has integrated this technology into standard face masks to detect the presence of the SARS-CoV-2 virus in a patient's breath. The button-activated mask ...

Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker -- a wireless, battery-free, fully implantable pacing device that disappears after it's no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body's biofluids over the course of five to seven weeks, without needing surgical extraction. The device wirelessly harvests energy from an external, remote antenna using near-field ...

A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence. The discovery, published in Nature Astronomy, also sheds new light on the thousand-year mystery of the supernova from A.D. 1054 that was visible all over the world in the daytime, before eventually becoming the Crab Nebula. Historically, supernovae have ...
