Telltale greenhouse gases could signal alien activity      (via sciencedaily.com)     Original source 

If aliens modified a planet in their solar system to make it warmer, we'd be able to tell. A new study identifies the artificial greenhouse gases that would be giveaways of a terraformed planet.

Marsquakes may help reveal whether liquid water exists underground on red planet      (via sciencedaily.com)     Original source 

If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars -- or marsquakes -- could offer a new tool in the search.

First of its kind detection made in striking new Webb image      (via sciencedaily.com)     Original source 

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA's James Webb Space Telescope's Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.

Geologists expect Chang'e-6 lunar surface samples to contain volcanic rock and impact ejecta      (via sciencedaily.com)     Original source 

On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the Moon. In anticipation of this historic event, scientists are publishing their predictions for the unique materials that may be found in the CE-6 samples.

Myths about intermittent fasting, debunked      (via sciencedaily.com)     Original source 

Research shows that the increasingly popular weight-loss strategy is safe. Intermittent fasting has become an increasingly popular way to lose weight without counting calories. And a large body of research has shown it s safe. Still, several myths about fasting have gained traction.

Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer      (via sciencedaily.com)     Original source 

New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as effective as common inorganic synthetic fertilizers but avoids several side effects that harm the environment, making it an eco-friendly alternative.

Removal of excess chloride ions by plants when subjected to salt stress      (via sciencedaily.com)     Original source 

Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.

How cells boost gene expression      (via sciencedaily.com)     Original source 

The function of non-coding RNA in the cell has long been a mystery to researchers. Unlike coding RNA, non-coding RNA does not produce proteins -- yet it exists in large quantities. A research team has now discovered an important function of antisense RNA (asRNA): the researchers found that asRNA acts as a 'superhighway' in cell transport and thus accelerates gene expression.

Star clusters observed within a galaxy in the early Universe      (via sciencedaily.com)     Original source 

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.

Simple test for flu could improve diagnosis and surveillance      (via sciencedaily.com)     Original source 

Fewer than one percent of people who get the flu every year get tested, in part because most tests require trained personnel and expensive equipment. Now researchers have developed a low-cost paper strip test that could allow more patients to find out which type of flu they have and get the right treatment. The test uses CRISPR to distinguish between the two main types of seasonal flu, influenza A and B, as well as seasonal flu subtypes H1N1 and H3N2. It can also identify strains that resist antiviral treatment, and with further work, could potentially detect swine and avian flu strains, including H5N1, which is currently infecting cattle.

Boosting biodiversity without hurting local economies      (via sciencedaily.com)     Original source 

Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.

Unifying behavioral analysis through animal foundation models      (via sciencedaily.com)     Original source 

Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology makes it possible for a single deep learning model to detect animal motion across many species and environments. This 'foundational model', called SuperAnimal, can be used for animal conservation, biomedicine, and neuroscience research.

How to make aging a 'fairer game' for all wormkind      (via sciencedaily.com)     Original source 

Researchers have discovered a new fundamental mechanism governing the rules of ageing in worms. The researchers were able to manipulate the mechanism through genetic interventions which dramatically extend not just the lifespan of the worms, but also their health-span. In other words, trading weak, frail old age with vigorous golden years -- all without altering their diet, environment or other external factors.

Guiding humanity beyond the moon      (via sciencedaily.com)     Original source 

What actually happens to the human body in space? While scientists and researchers have heavily researched how various factors impact the human body here on Earth, the amount of information available about changes that occur in the body in space is not as well-known. Scientists have been studying for years how the body, specifically on the molecular side, changes in space. Recently, findings depict how the modern tools of molecular biology and precision medicine can help guide humanity into more challenging missions beyond where we've already been.

Iron meteorites hint that our infant solar system was more doughnut than dartboard      (via sciencedaily.com)     Original source 

Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but were transported to the outer solar system. New research shows that for this to have happened, the protoplanetary disk of our solar system had to have been doughnut-shaped because the refractory metals could not have crossed the large gaps in a target-shaped disk of concentric rings. The paper suggests that the refractory metals moved outward as the protoplanetary disk rapidly expanded, and were trapped in the outer solar system by Jupiter.

Supermassive black hole appears to grow like a baby star      (via sciencedaily.com)     Original source 

Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating, magnetic wind that they believe is helping a galaxy's central supermassive black hole to grow. The swirling wind, revealed with the help of the ALMA telescope in nearby galaxy ESO320-G030, suggests that similar processes are involved both in black hole growth and the birth of stars.
