- 21/4/22 21:04
Researchers utilized genomic tools to investigate potential health effects of exposure to ionizing radiation, a known carcinogen, as a result of the 1986 Chernobyl accident. One study found no evidence that genetic changes associated with radiation exposure are passed to children, while the second study documented the genetic changes in the tumors of people who developed thyroid cancer after being...
Scientists uncover structure of light-driven enzyme with potential biofuel applications
- ScienceDaily
- 21/4/22 21:04
Although many organisms capture and respond to sunlight, enzymes - proteins that catalyze biochemical reactions - are rarely driven by light. A new study captures the full cycle of complex structural changes in an enzyme called FAP as it transforms a fatty acid into alkanes or alkenes.
Immune system, not COVID virus, may pose greatest risk to pregnant women
- ScienceDaily
- 21/4/22 21:04
Scientists investigated whether the COVID-19 virus could be affecting placental tissue of infected expectant mothers. Their analysis found that while evidence of the virus in the placenta is rare, the placenta in infected mothers tended to exhibit a much higher level of immune system activity than those of non-infected pregnant women, they report.

Experimental drug shows potential against Alzheimer's disease
- ScienceDaily
- 21/4/22 21:04
Researchers have designed an experimental drug that reversed key symptoms of Alzheimer's disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting and recycling them.
Anti-aging compound improves muscle glucose metabolism in people
- ScienceDaily
- 21/4/22 21:03
In the first clinical trial of nicotinamide mononucleotide (NMN), researchers have found that the compound previously demonstrated to counteract aspects of aging and improve metabolic health in mice also has clinically relevant effects in people.
Researchers trace spinal neuron family tree
- ScienceDaily
- 21/4/22 21:03
Spinal cord nerve cells branching through the body resemble trees with limbs fanning out in every direction. But this image can also be used to tell the story of how these neurons, their jobs becoming more specialized over time, arose through developmental and evolutionary history. Researchers have traced the development of spinal cord neurons using genetic signatures and revealed how different...
Salad or cheeseburger? Your co-workers shape your food choices
- ScienceDaily
- 21/4/22 21:03
Employees' cafeteria purchases -- both healthy and unhealthy foods -- were influenced by their co-workers' food choices, found a large, two-year study of hospital employees. The study made innovative use of cash register data to gain insights into how individuals' social networks shape their health behavior. The research suggests we might structure future efforts aimed at improving population...
MERS DNA vaccine induces immunity, protects from virus challenge in preclinical model
- ScienceDaily
- 21/4/22 18:36
A synthetic DNA vaccine candidate for Middle East respiratory syndrome coronavirus (MERS-CoV) induced potent immune responses and afforded protective efficacy in non-human primate models when given intradermally in abbreviated, low-dose immunization regimen.
Researchers show how 'theory of mind' influences advertising skepticism
- ScienceDaily
- 21/4/22 18:36
Product marketers should be clear in their messaging to avoid customer skepticism that makes them feel duped, according to new research. At issue in a new study was a social-cognitive construct called theory of mind, which considers how well people assess the mental states and apparent goals of others. Turns out, it affects a person's evaluation and willingness to buy a product.
Ground and satellite observations map building damage after Beirut explosion
- ScienceDaily
- 21/4/22 18:36
Days after the 4 August 2020 massive explosion at the port of Beirut in Lebanon, researchers were on the ground mapping the impacts of the explosion in the port and surrounding city. The goal was to document and preserve data on structural and façade damage before rebuilding.
The science of spin: Asteroseismologists confirm older stars rotate faster than expected
- ScienceDaily
- 21/4/22 18:36
Stars spin faster than expected as they age according to a new study which uses asteroseismology to shed new light on this emerging theory.
Stress test finds cracks in the resistance of harmful hospital bugs
- ScienceDaily

Research has identified critical factors that enable dangerous bacteria to spread disease by surviving on surfaces in hospitals and kitchens.
Inspired by nature, the research to develop a new load-bearing material
- ScienceDaily
- 21/4/22 18:36
Engineers have developed a new material that mimics human cartilage - the body's shock absorbing and lubrication system, and it could herald the development of a new generation of lightweight bearings.
Study of 'breakthrough' cases suggests COVID testing may be here to stay
- ScienceDaily
- 21/4/22 18:36
Two new cases helped scientists confirm what many have come to suspect: that people can get infected by SARS-CoV-2 variants even after successful vaccination. The findings suggest continued testing may be needed to prevent future outbreaks in a post-vaccine world.

Using exoplanets as dark matter detectors
- ScienceDaily
- 21/4/22 18:36
In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets. Astrophysicists suggest dark matter could be detected by measuring the effect it has on the temperature of exoplanets, which are planets outside our solar system.
Fighting harmful bacteria with nanoparticles

Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale.
