Scientists have developed a device that can identify a wide range of airborne gases and chemicals instantly.

A new study has identified markers of maternal stress -- both physical and psychological -- that may influence a baby's sex and the likelihood of preterm birth.

A new study reveals that commonly given hip and knee steroid intra-articular injections may be harmful in some patients with at-risk conditions or may cause complications that are not well understood.

In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more...

Researchers examined whether there is an association between arthritis and social isolation, and have identified the disease's contribution to social isolation.

Researchers have developed a new smart speaker skill that lets a device use white noise to both soothe sleeping babies and monitor their breathing and movement.

Researchers have developed a method for statistically predicting impacts of climate change on outbreaks of tularemia in humans. New results show that tularemia may become increasingly common in the future in high-latitude regions.

Two new symbiotic porcelain crab species have been described. One of them, from the South China Sea of Vietnam, inhabits the compact tube-like shelters built by the polychaete worm with other organisms. The other inhabits the intertidal vermetid snail formations in the Colombian Caribbean.

A fast knee-jerk 'ballistic' escape response and a more considered 'delayed' escape response are mediated by distinct and parallel neuronal pathways in zebrafish, according to a new study.

Farmers in Colombia's maize-growing region of Córdoba had seen it all: too much rain one year, a searing drought the next. Yields were down and their livelihoods hung in the balance. To better deal with climate stress, farmers in Colombia's maize-growing region of Córdoba needed information services that would help them decide what varieties to plant, when they should sow and how they should...

A new study finds that deaf infants exposed to American Sign Language are especially tuned to a parent's eye gaze, itself a social connection between parent and child that is linked to early learning.

Despite the evidence on risk factors for frailty, and the substantial progress that has been made in frailty awareness, the biological mechanisms underlying its development are still far from understood and translation from research to clinical practice remains a challenge. A new article provides an up-to-date clinical overview on preventing, identifying and managing frailty as well as its global...

In a recent clinical study, a regimen of combined oral and topical corticosteroids were effectively used to treat patients who suffer from severe CRS with nasal polyps and for whom surgery is often the first option.

Many of today's scientific processes are simulated using computer-driven mathematical models. But for a model to accurately predict how air flow behaves at high speeds, for example, scientists need supplemental real life data. Providing validation data, using up-to-date methods, was a key motivating factor for a recent experimental study.

Researchers have developed a machine learning system that may be able to warn doctors and patients about possible negative side effects that might occur when drugs are mixed.

With the help of new technologies, a team has confirmed that piranhas lose and regrow all the teeth on one side of their face multiple times throughout their lives. How they do it may help explain why the fish go to such efforts to replace their teeth.

A new study points to the need for better antibody validation, and outlines a process that other labs can use to make sure the antibodies they work with function properly.

Scientists have developed a molecular 'clock' that could reshape how pediatricians measure and monitor childhood growth and potentially allow for an earlier diagnosis of life-altering development disorders.

A research team found muscle cells treated with statins released the amino acid called glutamate at much higher levels than muscle cells that were untreated. As glutamate is a potent activator of muscle pain receptors, this release was proposed to trigger the sensation of muscle pain.

Life at the bottom of the social ladder may have long-term health effects that even upward mobility can't undo, according to new research in monkeys. A team studied 45 rhesus macaques. They found that monkeys who move up in the hierarchy still show the effects of their once-lowly status at the cellular level, even after they rise in rank.

In symptom-free individuals, the detection of misfolded amyloid-beta protein in the blood indicated a considerably higher risk of Alzheimer's disease -- up to 14 years before a clinical diagnosis was made. Amyloid-beta folding proved to be superior to other risk markers evaluated.

A chemical that has improved surgeries for brain cancer by making tumor cells fluorescent may also help doctors safely diagnose the disease and monitor its response to treatment.

Researchers have developed new insight on how the natural loss of foot muscles occurred in rodents and other species during their evolution.

New insights into how the molecular organization of charged molecules can be regulated to transform large-scale structures from ribbons to scroll-like cochleate structures could inform future drug-delivery strategies.
