Women with multiple sclerosis (MS) may not be at a higher risk of pregnancy complications like gestational diabetes, emergency cesarean section or stillbirth than women who do not have the disease, according to a new study.

Researchers demonstrate wireless transmission of uncompressed full-resolution 8K video using terahertz waves, accelerating research and development of Beyond 5G towards 6G.

Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors. Cancer immunotherapy has some remarkable successes, but its effectiveness has been limited to a relatively small handful of cancers. Researchers describe how advances in engineering models of tumors can greatly expand cancer...

Muscle wasting, or the loss of muscle tissue, is a common problem for people with cancer, but the precise mechanisms have long eluded doctors and scientists. Now, a new study gives new clues to how muscle wasting happens on a cellular level.

The native species has reached numbers that are contributing to drier soil and less vegetation - and may be more damaging to conservation areas than rabbits.

A phase 1 clinical trial testing a novel vaccine approach to prevent HIV has produced promising results, researchers announced today. The vaccine showed success in stimulating production of rare immune cells needed to start the process of generating antibodies against the fast-mutating virus; the targeted response was detected in 97 percent of participants who received the vaccine.

Piezoelectric materials hold great promise as sensors and as energy harvesters but are normally much less effective at high temperatures, limiting their use in environments such as engines or space exploration. However, a new piezoelectric device remains highly effective at elevated temperatures.

Students who attend the Georgia Prekindergarten Program are more likely to achieve in mathematics than those who do not attend pre-K, according to a new study.

The economic value of insect pollinators was $34 billion in the U.S. in 2012, much higher than previously thought. The team also found that areas that are economically most reliant on insect pollinators are the same areas where pollinator habitat and forage quality are poor.

Antimicrobial packaging is being developed to extend the shelf life and safety of foods and beverages. However, there is concern about the transfer of potentially harmful materials, such as silver nanoparticles, from these types of containers to consumables. Now, researchers illustrate that silver embedded in an antimicrobial plastic can leave the material and form nanoparticles in foods and...

New research suggests that a class of drugs called PARP inhibitors, designed to treat hereditary forms of ovarian and breast cancer, don't work the way we thought they did. It also paints a fuller picture of how they work, opening the door to improvements in next-generation drugs.

Researchers have developed a unique inkjet printing method for fabricating tiny biocompatible polymer microdisk lasers for biosensing applications. The approach enables production of both the laser and sensor in a room temperature, open-air environment, potentially enabling new uses of biosensing technologies for health monitoring and disease diagnostics.

A scientific detective story starting with a single patient in Pittsburgh unearths how the SARS-CoV-2 virus mutates to create new variants, including the UK strain B.1.1.7, and escapes neutralizing antibodies.

Researchers demonstrate why some ovarian cancer patients evolve better than others and suggest possible approaches to improve patient outcomes.

Making a choice quickly might appear effortless, but research that measured cardiovascular responses in the moment of making a choice, rather than after-the-fact, suggests that the apparent swift certainty might instead be a defense from having to think too deeply about the choices being presented to them.

For decades, scientists have wrestled with rival theories to explain how interactions between species, like competition, influence biodiversity. Tracking microbial life across the planet, researchers show that biodiversity does in fact foster further diversity in microbiomes that are initially less diverse. However, diversity rates plateau with increased competition for survival and space in more...

New technology has the potential to accelerate uptake and development of on-chip diagnostic techniques in parts of the world where rapid diagnoses are desperately needed to improve public health, mortality and morbidity.

The findings of a new study examining the behaviors of alligator and caiman hatchlings have enhanced our understanding of how we can conserve, and increase, the population of endangered crocodilian species.

An experimental single-dose, intranasal influenza vaccine was safe and produced a durable immune response when tested in a Phase 1 study. The investigational vaccine, called Ad4-H5-VTN, is a recombinant, replicating adenovirus vaccine designed to spur antibodies to hemagglutinin, a protein found on the surface of influenza viruses that attaches to human cells.

Scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous acid.

The Arctic Ocean was covered by up to 900 m thick shelf ice and was filled entirely with freshwater at least twice in the last 150,000 years. This surprising finding is the result of long-term research. With a detailed analysis of the composition of marine deposits, the scientists could demonstrate that the Arctic Ocean as well as the Nordic Seas did not contain sea-salt in at least two glacial...

Life changes influence the amount of physical activity in a person, according to a recent study. The birth of children and a change of residence, marital status and place of work all influence the number of steps of men and women in different ways.

A higher diversity of flowering plants increases the breeding success of wild bees and may help compensate for the negative effects of insecticides. This is what researchers have found in a large-scale experimental study.

Researchers have found that some bacteria on the skin of amphibians prevent growth of the fungus responsible for what has been dubbed 'the amphibian apocalypse'.
