Wine grapes are particularly finicky when it comes to their environment. For instance, heatwaves and droughts lead to earlier berry ripening and lackluster wine. And these types of episodes are expected to intensify as Earth's climate changes. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have tweaked growing conditions for Cabernet Sauvignon grapes to slow down their ripening, which increased the levels of compounds associated with wine's characteristic floral and fruity notes.

Participants in a large-scale study who more commonly consumed a Southern-style diet - high in added fats, fried foods, processed meats and sugary drinks - had a higher risk of sudden cardiac death than people who had lower adherence to a Southern-style diet.

Following habitat-destroying wildfires, researchers found many male red-backed fairywrens failed to molt into their ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers. The birds' fat stores and stress hormone corticosterone remained at normal levels. While the findings are specific to this songbird, they may have implications for other species that don special coloration for mating.

A promising approach captures atmospheric carbon dioxide and then through CO2 electrolysis converts it into value-added chemicals and intermediates, like ethanol. Reducing the energy consumption of this high-power process has been underexplored. In ACS Energy Letters, researchers from the University of Illinois Urbana-Champaign report a new opportunity to use magnetism to reduce the energy required for CO2 electrolysis by up to 60% in a flow electrolyzer.

All these preclinical data strongly suggest that the inhibition of mTORC1 and PLK1 proteins may be a promising therapeutic approach for NSCLC patients

Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. But in a new review paper accepted to the Astrophysical Journal, Freedman gives an overview of the most recent observations. Her conclusion: the latest observations are beginning to close the gap. That is, there may not be a conflict after all, and our standard model of the universe does not need to be significantly modified.

The link between obesity and the risk of endometrial cancer has been well documented. A new study, however, shows that an even lower body mass index (BMI) than previously thought can signal an increased risk in Asian women with postmenopausal bleeding. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

How common COVID-19 is among infants may depend on the degree of the pandemic virus circulating in a community.

Much has been rightfully made of the valiant work of doctors and nurses during the coronavirus pandemic. But what of infection preventionists (IP), whose job was to keep those workers and their facilities safe, and who many Americans do not even know exist?

A new mathematical model has been developed by QUT researchers to uncover land clearing when satellite imagery is obstructed by clouds.

By using a fluid mixing process instead of expensive, high-temperature fabrication methods, researchers may have demonstrated a pathway to producing flexible, printed solar cells on a cost effective, industrial scale.

A combination of factors makes a warming climate beneficial to rattlesnakes. The snakes are experts at thermoregulation, need few calories to survive, and would likely have more active time seasonally and during a given day.

Rutgers researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.

A new study shows that colleges students are experiencing significant grief reactions in response to the COVID-19 pandemic.

A University of Arkansas researcher and international colleagues found that employed individuals, on average, are 35.3% more likely to be infected with the flu virus.

A new study in the Journal of the American Heart Association shows that a breathing exercise known as Inspiratory Muscle Strength Training can reduce blood pressure in weeks, with benefits on par with daily exercise or medication.

Male jackdaws don't stick around to console their mate after a traumatic experience, new research shows.

A new analysis of 58 studies and 44305 patients published in Anaesthesia (a journal of the Association of Anaesthetists) shows that, contrary to some previous research, being male and increasing body mass index (BMI) are not associated with increased mortality in COVID-19 in patients admitted into intensive care (ICU).

The AIDS Clinical Trials Group (ACTG), the largest global HIV research network, today announced that findings from a sub-study of REPRIEVE (A5332/A5332s, an international clinical trial studying heart disease prevention in people living with HIV) have been published in the Journal of the American Medical Association Network Open. The study found that approximately half of study participants, who were considered by traditional measures to be at low-to-moderate risk of future heart disease, had atherosclerotic plaque in their coronary arteries.

Researchers at the University of Arizona believe the liver may hold the key to new, preventative Type 2 diabetes treatments.
