Canaries lava peninsula doubles in size as wind change raises risk
Lava from the erupting volcano on La Palma in Spain's Canary Islands that began cascading into the ocean two days ago has already covered an area bigger than 25 football pitches, with concerns rising over worsening air quality in nearby residential areas, experts said on Thursday.
EXPLAINER: Fountaining Hawaii lava creates molten rock lake
Kilauea, one of the most active volcanos on Earth, began erupting on Hawaii's Big Island Wednesday. The eruption is not in an area with homes and is entirely contained within Hawaii Volcanoes National Park.
A kagome lattice superconductor reveals a 'cascade' of quantum electron states
Researchers have discovered a complex landscape of electronic states that can co-exist on a kagome lattice, resembling those in high-temperature superconductors, a team of Boston College physicists reports in an advance electronic publication of the journal Nature.
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...
Scientists use nuclear physics to probe Floridan Aquifer threatened by climate change
As rising sea levels threaten coastal areas, scientists are using an emerging nuclear dating technique to track the ins and outs of water flow.
Brands can boost their own reputations and sales by praising rivals
Whether they're beefing on billboards or sparring on social media, big brands are known for taking jabs at their competitors (see the famous "Get a Mac" ads or "the chicken sandwich wars").
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...
COVID-19 hospitalizations increase among unvaccinated pregnant women

Unvaccinated pregnant women are increasingly being hospitalized with COVID-19 during a nationwide surge of the Delta variant, according to researchers.
New treatment for inflammatory bowel disease: Opioids may cure that 'bad gut feeling'
- ScienceDaily
- 21/9/30 23:10
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...
Scientists use nuclear physics to probe Floridan Aquifer threatened by climate change

Scientists used a nuclear dating technique to study the dynamics of the Floridan Aquifer. The findings show the promise of this emerging technique to help understand geological processes and to forecast the effects of climate change on coastal aquifers.
Study on African buffalo offers insights on persistence of highly contagious pathogens
- ScienceDaily
- 21/9/30 22:04
A new study on foot-and-mouth disease among buffalo in South Africa could help explain how certain extremely contagious pathogens are able to persist and reach endemic stage in a population, long after they've burned through their initial pool of susceptible hosts.
New metamaterial with unusual reflective property could boost your Wi-Fi signal

- 21/9/30 22:04
Engineers have achieved a practical mechanism for 'full-duplex nonreciprocity,' a property in metamaterials that allows for manipulation of both incoming and reflective beams of light.
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.
Scientists detect new landslides on U.S. West Coast
SMU geophysicists have used satellite imagery to identify more than 600 slow-moving landslides occurring near the U.S. West Coast
Science journal calls on scientists to combat Facebook misinformation
Leading US journal Science on Thursday issued a rare editorial calling for scientists to fight back against the COVID misinformation that proliferates on Facebook.
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...
New study on African buffalo offers insights on persistence of highly contagious pathogens
A new Oregon State University study on foot-and-mouth disease among buffalo in South Africa could help explain how certain extremely contagious pathogens are able to persist and reach endemic stage in a population, long after they've burned through their initial pool of susceptible hosts.
