University of Maryland researchers discovered a way that Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis, can cause a person's immune cells to lower their defenses. Specifically, they identified a gene in the bacterium that suppresses immune defenses in infected human cells, which could exacerbate the infection. The findings were published on July 29, 2021, in the journal...

Researchers have discovered the mechanism that underlies spitting in the roundworm C. elegans -- expanding our understanding of how neurons control muscle cells to shape behavior.

Sleep researchers have found it's possible to determine the timing of a person's internal biological clock via a single blood draw. Ultimately, the findings could lead to a simple blood test for assessing circadian rhythm and personalized recommendations for when people should eat, sleep, exercise and take medications.

Using a CeO2 catalyst, researchers develop an effective catalytic process for the direct synthesis of polycarbonate diols without the need for dehydrating agents. The high yield, high selective process has CO2 blown at atmospheric pressure to evaporate excess water by-product allowing for a catalytic process that can be used with any substrate with a boiling point higher than water.

Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study directly investigates what PIEZO channels are doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.

Researchers compiled a dataset of 209 crustacean and 155 mollusk species from 16 mangrove forests around the world. They found that mangroves, when compared with other ecosystems, are among those with the lowest functional redundancy among resident fauna recorded to date, which suggests that these coastal vegetations are among the most precarious ecosystems in the world.

Primates who are more tolerant of each other use vocal communication more than their stricter counterparts, research shows.

Researchers have discovered long narrow dust filaments which surround and feed black holes in the centers of galaxies, and which could be the natural cause of the darkening of the centers of many galaxies when their nuclear black holes are active.

A study has found photos of a person's living space can accurately point at personality traits and the mood of the people who live there, especially as a person gets older. Applying the findings could help lead to happier lives, including for older adults with frailty or cognitive impairment that has led them to be transferred from their homes to long-term care facilities.

The shoots of plants get all of the glory, with their fruit and flowers and visible structure. But it's the portion that lies below the soil — the branching, reaching arms of roots and hairs pulling up water and nutrients — that interests some plant physiologist and computer scientist the most.

For years scientists have been debating what might lay under the Martian planet's south polar cap after bright radar reflections were discovered and initially attributed to water. But now, a new study puts that theory to rest and demonstrates for the first time that another material is most likely the answer.

Researchers report the identification of a new target for the PARP inhibitor drug talazoparib and show that combination treatment with talazoparib and the WEE1 inhibitor adavosertib results in enhanced anti-cancer effects.

Interventions to prevent obesity in children typically don't target the first 1,000 days of life - -a critical period in which environmental and nutritional cues can increase the risk for obesity. A new study demonstrates how changing parents' health behavior and how clinicians deliver care to mothers and infants decreased excess weight gain in infants.

Treating obese mice with the cytokine known as TSLP led to significant abdominal fat and weight loss compared to controls. The animal model findings support the possibility that increasing sebum production via the immune system could be a strategy for treating obesity in people.

Neuroscientists have connected some of the dots to reveal the brain networks that give anxiety influence over decisions. The group has published a review that synthesizes results from years of brain measurements in rats and primates and relates these findings to the human brain.

New research has identified a 100-million-year-old weevil unlike any other known fossilized or living weevil.

A new study shows that people who eat a diet that includes at least half a serving per day of foods high in flavonoids like strawberries, oranges, peppers and apples may have a 20% lower risk of cognitive decline. The study looked at several types of flavonoids, and found that flavones and anthocyanins may have the most protective effect.

Researchers say they have added to evidence that the compound farnesol, found naturally in herbs, and berries and other fruits, prevents and reverses brain damage linked to Parkinson's disease in mouse studies.

Children whose parents regularly smoke or vape marijuana may experience viral respiratory infections, such as the common cold, more frequently than those whose parents do not smoke, according to a new study.

Caecilians have arrived in Miami. Florida Fish and Wildlife officers captured one of the obscure legless amphibians in the Tamiami Canal, the first example of an introduced caecilian in the U.S.

New research shows that mice can teach us about decision-making strategies. Mice in the study autonomously trained themselves to make decisions about detailed pictures on a screen, and the results illuminated the underlying, sometimes random nature of the decisions.

Matrix, process, or something else? The structure of an organization is of little significance for its success, as long as there is systems intelligence, according to a new study.

Researchers have developed nanobodies that efficiently block the coronavirus SARS-CoV-2 and its new variants.

Dark mode is unlikely to make a big difference to battery life with the way that most people use their phones on a daily basis, says a new study. That doesn't mean that dark mode can't be helpful, though.
