Does your community have a personality type?

Geographic sorting along ideological lines is on the rise. U.S. counties and regions differ in political ideology. But do they differ in personality as well? Further, are people who 'fit' their communities healthier, happier, or more highly achieving than those who do not? A new study reveals communities are diverse in terms of personality as well as demographics, and having like-minded people in one's community is associated with positive outcomes... Read more ›

New approach to tackling bacterial infections identified

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the... Read more ›

Many excess deaths attributed to natural causes are actually uncounted COVID-19 deaths, new analysis reveals

A new study provides the first concrete data showing that many of these excess deaths were indeed uncounted COVID-19 deaths. The study compared reported COVID-19 deaths to excess deaths due to non-COVID, natural causes, such as diseases and chronic illnesses, and found that increases in non-COVID excess deaths occurred at the same time or in the month prior to increases in reported COVID-19 deaths in most US counties.

Researchers discover key to molecular mystery of how plants respond to changing conditions

A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal... Read more ›

Complex tree canopies help forests recover from moderate-severity disturbances

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens. Read more ›

New cell therapy shows promise with ARDS patients

An initial trial suggests that a new drug, originally developed for use with cancer patients, could improve the survival of patients with acute respiratory distress syndrome (ARDS). The patients in the trial were all critically unwell with ARDS, caused by severe Covid-19, and the invariant natural killer T (iNKT) cell therapy triggered an immune response in these individuals.

Chemists decipher reaction process that could improve lithium-sulfur batteries

Lithium-sulfur batteries have exceptional theoretical capacity and performance in combination with an element in abundant supply. But the intricate reaction mechanism, particularly during discharge, has been challenging to solve. Researchers have identified the key pathways to a complex sulfur reduction reaction that leads to energy loss and reduced battery life span. The study's findings establish the whole reaction network for the first time and offer insight into electrocatalyst design for... Read more ›

Improving fuel cell durability with fatigue-resistant membranes

In hydrogen fuel cells, electrolyte membranes frequently undergo deformation and develop cracks during operation. A research team has recently introduced a fatigue-resistant polymer electrolyte membrane for hydrogen fuel cells, employing an interpenetrating network of Nafion (a plastic electrolyte) and perfluoropolyether (a rubbery polymer). This innovation will not only improve fuel cell vehicles but also promises advancements in diverse technologies beyond transportation, spanning applications from drones Read more ›

How a city is organized can create less-biased citizens

A new study presents data and a mathematical model to explain why there is more unconscious, or implicit, racial bias in some cities than others. The study, which brings together the math of cities with the psychology of how individuals develop unconscious racial biases, suggests that a city's level of implicit bias depends on how populous, diverse, and segregated that city is.

Mystery of novel clove-like off-flavor in orange juice solved

A research team has solved the mystery of a novel clove-like off-flavor in orange juice, the cause of which was previously unknown. The study proves for the first time that the undesirable flavor note is due to the odorant 5-vinylguaiacol. As the results of the study show, the substance is mainly produced during the pasteurization process when residues of a cleaning agent react with a natural orange juice component under...
