Salt stress alters legume responses to symbiotic rhizobacteria by modulating gene expression

Crop legumes are an integral part of sustainable agriculture, as several of these species represent an important protein source for both human and animal populations. Legumes engage in a unique and beneficial interaction with a group of soil bacteria, collectively called rhizobia. Rhizobium-legume symbioses lead to the development of new plant organs on the roots called nodules, which host...

Using dunes to interpret wind on Mars

Dunes develop when wind-blown sand organizes into patterns, most often in deserts and arid or semi-arid parts of the world. Every continent on Earth has dune fields, but dunes and dune-like sand patterns are also found across the solar system: On Mars, Venus, Titan, Comet 67P, and Pluto. On Earth, weather stations measure the wind speed and direction, allowing us to predict and understand airflow...

Study: Just 1 of 5 people with disabilities works from home; millions still do not have the option

Working from home could revolutionize job opportunities for people with mobility impairments, chronic medical conditions, and other disabilities, but a towering obstacle still stands in the way more than 18 months into the pandemic. A report by the Rutgers Program for Disability Research finds a disproportionate number of people with disabilities work in places like factories, restaurants, and...

Linker histones tune the length and shape of chromosomes

Human life hinges on the ability of our cells to cram six feet of DNA into a 10-micron nucleus—equivalent to fitting a mile of string inside one green pea. But stuffing genes into cramped quarters is only half the battle. The DNA must also remain organized, carefully coiled into loops that ensure the information remains readily accessible and not a tangled mess.

Most cases of never-smokers’ lung cancer treatable with mutation-targeting drugs

Despite smoking's well-known role in causing lung cancer, a significant number of patients who develop lung tumors have never smoked. While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug...

New treatment for inflammatory bowel disease: Opioids may cure that 'bad gut feeling'

Opioid receptors play key roles in regulating our senses and emotions. Recently, their discovery outside the nervous system raised several questions about the effects of opioids on the immune system. Now, researchers have shown that KNT-127 -- a drug that targets delta opioid receptors -- can reduce pro-inflammatory signals in the colon. Their research highlights the immunomodulatory properties of...

Flu and Covid jabs safe to be given at same time, study finds

Clinical trial on joint flu, Pfizer and AstraZeneca vaccinations reported only mild to moderate side-effectsCoronavirus – latest updatesSee all our coronavirus coverageFlu jabs are safe to give at the same time as the Pfizer or AstraZeneca Covid vaccines, according to the first clinical trial to investigate co-administering the shots in a single appointment.While some people experienced more...

Dynamic pregnancy intentions

A study found that pregnancy intentions often change over as short as a 12-month time period, and that they specifically vary with partner status, household income, and employment status.

Optically generated quantum fluids of light reveal exotic matter-wave states in condensed matter physics

Researchers from Skoltech and the University of Southampton, U.K., have used all-optical methods to create an artificial lattice whose nodes house polaritons—quasiparticles that are half-light and half-matter excitations in semiconductors. This so-called Lieb lattice, which usually does not occur in nature, enabled the team to demonstrate breakthrough results important for condensed matter...
