Sudden infant death syndrome (SIDS) accounts for about 37% of sudden unexpected infant deaths a year in the U.S., and the cause of SIDS has remained largely unknown. On Saturday, researchers from The Children’s Hospital Westmead in Sydney released a study that confirmed not only how these infants die, but why.

SIDS refers to the unexplained deaths of infants under a year old, and it usually occurs while the child is sleeping. According to Mayo Clinic, many in the medical community suspected this phenomenon could be caused by a defect in the part of the brain that controls arousal from sleep and breathing. The theory was that if the infant stopped breathing during sleep, the defect would keep the child from startling or waking up.

The Sydney researchers were able to confirm this theory by analyzing dried blood samples taken from newborns who died from SIDS and other unknown causes. Each SIDS sample was then compared with blood taken from healthy babies. They found the activity of the enzyme butyrylcholinesterase (BChE) was significantly lower in babies who died of SIDS compared to living infants and other non-SIDS infant deaths. BChE plays a major role in the brain’s arousal pathway, explaining why SIDS typically occurs during sleep.

Results from the first phase 3 trial of using MDMA for PTSD along with talk therapy found the drug to be effective.

Glucose is the sugar we absorb from the foods we eat. It is the fuel that powers every cell in our bodies. Could glucose also power tomorrow’s medical implants?

Engineers at MIT and the Technical University of Munich think so. They have designed a new kind of glucose fuel cell that converts glucose directly into electricity. The device is smaller than other proposed glucose fuel cells, measuring just 400 nanometers thick. The sugary power source generates about 43 microwatts per square centimeter of electricity, achieving the highest power density of any glucose fuel cell to date under ambient conditions.

Dr. Thomas Lehner was tired of his research repeatedly hitting a wall.

A scientist at the National Institute of Mental Health, Lehner studies the genetic underpinnings of neuropsychiatric disorders. Teasing out associated genes turned out to be relatively simple. Schizophrenia, for example, is linked to small variations in some 360 genes.

The problem is identifying the ones that really matter—culprit gene variants that can be turned into predictive tests, similar to the BRCA gene for breast cancer.

COVID-19 may prove to be just the first in a series of pandemics throughout the 21st century – unless humans drastically improve their relationship with animals and the natural world.

Russian scientists have synthesized a new ultra-hard material consisting of scandium containing carbon. It consists of polymerized fullerene molecules with scandium and carbon atoms inside. The work paves the way for future studies of fullerene-based ultra-hard materials, making them a potential candidate for photovoltaic and optical devices, elements of nanoelectronics and optoelectronics, and biomedical engineering as high-performance contrast agents. The study was published in Carbon.

The discovery of new, all-carbon molecules known as fullerenes almost 40 years ago was a revolutionary breakthrough that paved the way for fullerene nanotechnology. Fullerenes have a spherical shape made of pentagons and hexagons that resembles a soccer ball, and a cavity within the carbon frame of fullerene molecules can accommodate a variety of atoms.

The introduction of metal atoms into carbon cages leads to the formation of endohedral metallofullerenes (EMF), which are technologically and scientifically important owing to their unique structures and optoelectronic properties.
