Infection with the virus that causes COVID-19 can trigger an immune response that lasts well beyond the initial infection and recovery -- even among people who had mild symptoms or no symptoms at all, according to investigators.

A new study shows how cell membranes curve to create the 'mouths' that allow the cells to consume things that surround them.

The secret to producing large batches of stem cells more efficiently may lie in the near-zero gravity conditions of space. Scientists have found that microgravity has the potential to contribute to life-saving advances on Earth by facilitating the rapid mass production of stem cells.

Down near the Earth's core, there are zones where seismic waves slow to a crawl. New research finds that these enigmatic and descriptively-named ultra-low velocity zones are surprisingly layered. Modeling suggests that it's possible some of these zones are leftovers from the processes that shaped the early Earth -- remnants of incomplete mixing like clumps of flour in the bottom of a bowl of...

Immunotherapies called chimeric antigen receptor (CAR) T cells use genetically engineered versions of a patient's own immune cells to fight cancer. These treatments have energized cancer care, especially for people with certain types of blood cancers. Now, scientists have developed new CAR T cells that can do something their predecessors cannot: Make drugs.

Cancer deaths rose to 10 million and new cases jumped to over 23 million globally in 2019, according to a new scientific study.

COVID-19 vaccination of expectant mothers elicits levels of antibodies to the SARS-CoV-2 outer 'spike' protein at the time of delivery that don't vary dramatically with the timing of vaccination during pregnancy and thus don't justify delaying vaccination, according to a new study.

A healthy, comprehensive diet that lowers the body's inflammation reduces the risk of gestational diabetes mellitus, reveals a new study.

A new study shows that among patients with obesity, prior weight loss achieved with bariatric surgery was associated with a 60 percent lower risk of developing severe complications from COVID-19 infection.

Atmospheric carbon dioxide (CO2) levels have increased significantly over the last 50 years, resulting in higher global temperatures and abrupt changes to Earth's climate. Carbon capture and storage (CCS) is one of the new technologies that scientists hope will play an important role in tackling the climate crisis. It involves the capture of CO2 from emissions from industrial processes, or from...

Researchers have shown in mice models of Alzheimer's disease, frontotemporal dementia, and dementia with Lewy bodies, that the intranasal administration of rifampicin and resveratrol in combination is safer and improves cognitive function more than rifampicin alone. The research results are expected to lead to the development of safe and effective nasal spray for the prevention of dementia.

A team of scientists has developed a 'smart' food packaging material that is biodegradable, sustainable and kills microbes that are harmful to humans. It could also extend the shelf-life of fresh fruit by two to three days.

For the first time, scientists have recovered ancient human DNA from the sticky glue head lice use to attach their eggs to their host's hair. The new technique was trialled on mummified remains and the DNA has revealed clues about how the people died and the movements of populations thousands of years ago.

Recent studies have shown variation in the gene-expression profile and phenotype of microglia across brain regions and between different age and disease states. But the molecular mechanisms that contribute to these transcriptomic changes in the human brain are not well understood. Now, a new study targets the methylation profile of microglia from human brain.

Recent progress in camera systems, image analysis, and machine learning have made optical-based gesture recognition a more attractive option in most contexts. However, current methods are hindered by a variety of limitations, including high computational complexity, low speed, poor accuracy, or a low number of recognizable gestures.

A potential new route to the diagnosis and treatment of ARDS comes from studying how neutrophils -- the white blood cells responsible for detecting and eliminating harmful particles in the body -- differentiate what materials to uptake by the material's surface structure, and favor uptake of particles that exhibit 'protein clumping,' according to new research.

A team of researchers has found a link between the way that cells produce energy for brain function and the mutated genes found in Alzheimer's disease.

Research to evaluate the clinical characteristics and outcomes of fully vaccinated patients with cancer who had breakthrough COVID-19 infections indicates they remained at high risk for hospitalization and death.

Researchers used a novel finite-fault inversion method with seismometer data from around the world to investigate a deep intraslab earthquake that occurred on March 4, 2021, off the northeastern tip of New Zealand's North Island. This imaging revealed complex rupture geometry that included shallow faulting with trench-perpendicular extension and unusual deep faulting with trench-parallel...

When cells are exposed to ionizing radiation, more destructive chain reactions may occur than previously thought. An international team led by researchers has now observed intermolecular Coulombic decay in organic molecules. This is triggered by ionizing radiation such as from radioactivity or from space. The effect damages two neighboring molecules and ultimately leads to the breaking of bonds...

An innovative approach could turn nanoparticles into simple storage devices for hydrogen. The concept uses nanoparticles made of the precious metal palladium.

Scientists have identified a key signal that the fetus uses to control its supply of nutrients from the placenta, revealing a tug-of-war between genes inherited from the father and from the mother. The study, carried out in mice, could help explain why some babies grow poorly in the womb.

The analysis of ancient DNA preserved in sediments is an emerging technology allowing for the detection of the past presence of humans and other animals at archaeological sites. Yet, little is known about how DNA is preserved in sediment for long periods of time. Scientists have now shed light on the matter by isolating DNA from solid blocks of undisturbed sediment that are embedded in plastic...

Researchers have found that individuals with a certain HLA type may be able to mount a killer T cell response to COVID-19, thanks to the T cells responding to a portion of the virus's spike protein that is also present in seasonal coronaviruses that cause the common cold. This work could help explain the different responses between populations, and could potentially be used as a way to develop a...
