Allergic reactions to the new mRNA-based COVID-19 vaccines are rare, typically mild and treatable, and they should not deter people from becoming vaccinated, according to researchers.

Researchers have made a surprise discovery about how immune 'sentinel' cells are maintained, which could have implications for drugs in development for treating cancer.

Researchers attempted to unravel such mechanisms by adopting non-invasive diffusion magnetic resonance imaging (MRI) to study the brains of SLE patients, particularly the white matter, coupled with computerized neuropsychological assessment. White matter lies beneath the grey matter cortex in the human brain and comprises millions of bundles of nerve fibers that transmit signals to different brain...

Imagine having your own digital personal chef; ready to cook whatever you want, tailoring the shape, texture, and flavor just for you -- all at the push of a button. Engineers have been working on doing just that, using lasers for cooking and 3D printing technology for assembling foods. In their new study they discovered that laser-cooked meat shrinks 50% less, retains double the moisture content,...

Researchers have extracted Ancient DNA from human bones to re-write early Japanese history by underlining that modern day populations in Japan have a tripartite genetic origin -- a finding that refines previously accepted views of a dual genomic ancestry.

A new paper explores the idea that studying bats' responses to SARS-CoV-2 may provide key insights into how and when to best use existing therapies for COVID-19, and to develop new treatments. The paper is a major review of how the virus that has caused the current pandemic wreaks havoc on the human immune system.

A multi-disciplinary team has discovered and characterized a new mechanism that a simple yeast cell uses to acquire its shape.

Researchers have developed an approach to estimating when a person who is at high risk of Alzheimer's dementia but has no cognitive symptoms will start showing signs of cognitive decline. The approach is based on data from a single brain scan, combined with the person's age.

A new technique for measuring turbulent flows has been developed. By using fibers rather than particles -- the usual method of measurement -- the researchers could get a more detailed picture of turbulent flows.

Scientists have assembled a quantitative assessment for agriculture sustainability for countries around the world based not only on environmental impacts, but economic and social impacts, as well. The Sustainable Agriculture Matrix, or SAM, provides independent and transparent measurements of agricultural sustainability at a national level that can help governments and organizations to evaluate...

A newly discovered manipulation mechanism used by parasitic bacteria to slow down plant aging, may offer new ways to protect disease-threatened food crops. Research has identified a manipulation molecule produced by Phytoplasma bacteria to hijack plant development. When inside a plant, this protein causes key growth regulators to be broken down, triggering abnormal growth. The new findings show...

The capacity of coral reefs to provide ecosystem services such as food and jobs, relied on by millions of people worldwide, has declined by half since the 1950s, according to a new study. Other findings are equally bleak: the authors found that global coverage of living corals had declined by about half since the 1950s and consequently, the diversity of species had also declined, by more than 60...

Researchers are finding a link between the increased presence of certain bacteria in a gut biome and colon cancer.

Researchers have created a novel automated program that accurately and quickly counts micronuclei in stained images. Micronuclei are small nucleus-like structures that are markers of pathologies such as cancer. The development of this automated program will be useful for future research into micronuclei and may aid in the diagnosis and tracking of a range of pathologies.

Researchers are using high-tech 3D facial scans to give us a better understanding of the genetic causes of autism.

Researchers established an organoid biobank to search for the genes that are essential for the spreading of a SARS-CoV2 infection. Their study highlights the usefulness of organoids for basic research into coronaviruses, as well as highlighting potential drug targets.

Seeds that would otherwise lie dormant will spring to life with the aid of a new chemical.

Global warming is causing a rapid decline in sea-ice area, which affects weather patterns and, surprisingly, increases wave height in the Arctic. In a new study, Japanese scientists analyzed data from a 2018 research expedition into Chukchi Sea to demonstrate the peculiar link that exists between sea spray induced by high waves and the formation of ice-containing clouds. Their results pave the way...
