Researchers have developed an ultra-thin wireless device that grows to the surface of bone. Dubbed 'osseosurface electronics,' they could someday help physicians monitor bone health and healing over long periods.

Maya archaeologists have excavated salt kitchens where brine was boiled in clay pots over fires in pole and thatch buildings preserved in oxygen-free sediment below the sea floor in Belize. But where these salt workers lived has been elusive, leaving possible interpretations of daily or seasonal workers from the coast or even inland. This gap left nagging questions about the organization of...

Researchers uncovered a new way to indirectly activate T cells that can target tumors, by recruiting a population of helper immune cells called dendritic cells.

New research shows that different psychotherapists use common treatment processes to varying benefits for patients.

Mathematical model indicates SARS-CoV-2 variants that combine enhanced transmissibility with the ability to escape immunity cause more infections than variants with either trait alone. Understanding which type of variants are most likely to increase infections and pandemic severity could help researchers and public health officials interpret the significance of novel and existing variants and...

Scientists successfully induced gene expression from a DNA and evolution through continuous replication extracellularly using cell-free materials alone for the first time. By adding the genes necessary for transcription and translation to the artificial genomic DNA, it could be possible to develop artificial cells that can grow autonomously, and it will be expected to produce efficient useful...

Researchers presented new insights for improving the health span by just regulating the activity of a protein. A research group has identified a single amino acid change in the tumor suppressor protein phosphatase and tensin homolog (PTEN) that dramatically extends healthy periods while maintaining longevity.

Obesity, diabetes and gastrointestinal cancer are frequently linked to an unhealthy diet. However, the molecular mechanisms responsible for this are not fully understood. Researchers have gained some new insights that help to better understand this connection. These findings provide an important basis for the development of non-invasive therapies.

An unborn baby could become infected with COVID-19 if their gut is exposed to the SARS-CoV-2 virus, finds a new study.

A plant-based antiviral has been found to be just as effective at treating all variants of the virus SARS-CoV-2, even the highly infectious Delta variant.

Riluzole, a drug approved to treat amyotrophic lateral sclerosis (ALS), a disease affecting nerve cells controlling movement, could slow the gradual loss of a particular brain cell that occurs in Niemann-Pick disease type C1 (NPC1), a rare genetic disorder affecting children and adolescents, suggests a study in mice.

Researchers have developed a new probiotic bacteria designed to break down solid cancer cell walls and make other therapies more effective.

A research team revealed the molecular architecture of fungal cell walls and the structural responses to stresses, aiding the development of antifungal drugs targeting cell wall components.

Scientists have discovered that ferroelectric bubbles remain intact and retain their electronic and electromechanical (piezoelectric) properties in a freestanding state. The discovery offers promise for novel microelectronics and energy-related applications.

Understanding how climate change will affect the flooding of rivers may become easier with a new framework for assessing flood risk that's been developed by an interdisciplinary team.

Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of applications, according to an international team of researchers.

Widely accepted myths that urbanization negatively impacts food and land use biodiversity are incorrect, according to a team of researchers who developed a framework for evaluating this intersection.

Antibodies after COVID-19 vaccination peaked higher for women and younger people than men and individuals over the age of 65, respectively, but levels dropped by half within six months for everyone in a study group.

People taking TNF inhibitors, a kind of immunosuppressive drug used to treat rheumatoid arthritis and other autoimmune conditions, produced a weaker and shorter-lived antibody response after two doses of Pfizer's COVID-19 vaccine, according to a new study. A third vaccine dose drove antibody levels back up, indicating that this additional dose may provide protection as the virus's delta variant...

Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques and guinea pigs, researchers report. The finding could help pave the way for better understanding and diagnosis of auditory processing deficits.

It sounds like a party trick: scientists can now look at the brain activity of a tiny worm and tell you which chemical the animal smelled a few seconds before. But the findings of a new study are more than just a novelty; they help the scientists better understand how the brain functions and integrates information.

Phages are viruses that infect bacteria and can also be used to treat human infections. However, as with antibiotics, bacteria can readily evolve resistance to phage attack, highlighting a key limitation to the use of phages as therapeutics. Now, researchers have shown that the naturally occurring phage A1-1 kills Shigella flexneri, a major cause of dysentery in sub-Saharan Africa and southern...

About 7.5 million Americans suffer from psoriasis, an autoimmune disease that shows up as patches of red, inflamed skin and painful, scaly rashes. Although there are effective treatments for psoriasis, not everyone responds to these therapies -- and for many, the relief is temporary. Scientists have discovered how a key protein called TWEAK damages skin cells in psoriasis patients. Their findings,...

Scientists are a step closer to breeding plants with genes from only one parent. New research led by plant biologists at UC Davis shows the underlying mechanism behind eliminating half the genome and could make for easier and more rapid breeding of crop plants with desirable traits such as disease resistance.
