Published Astronomers shed new light on formation of mysterious fast radio bursts


International team reports on a radio pulsar phase of a Galactic magnetar that emitted a fast radio burst in 2020; observations suggest unique origins for 'bursts' and 'pulses,' which adds to FRB formation theory.
Published 'Time-traveling' pathogens in melting permafrost pose likely risk to environment



Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study.
Published Solar batteries: New material makes it possible to simultaneously absorb light and store energy


Researchers are making progress on the design of a solar battery made from an abundant, non-toxic and easily synthesized material composed of 2D carbon nitride.
Published Scientists vacuum animal DNA from air in a Danish forest



Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.
Published James Webb Space Telescope sees Jupiter moons in a new light


Last year, JWST made spectral observations of Ganymede and infrared observations of Io. Absorption lines of hydrogen peroxide at Ganymede's poles indicate radiolysis of water ice by charged particles funneled by the moon's magnetic field. Io had two major eruptions, one associated with a forbidden emission line of sulfur monoxide. The latter supports a theory that SO is produced at volcanic vents in a thin atmosphere that allows forbidden emission before collisions destroy the excited state.
Published Self-healing plastic becomes biodegradable



Chemists develop mineral plastics with numerous positive properties from sustainable basic building blocks and, together with biologists, demonstrate the material's excellent microbiological degradability.
Published Hubble sees evaporating planet getting the hiccups


A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.
Published Listen to a star 'twinkle'



Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.
Published How to move communities away from flooding risks with minimal harm



As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.
Published Making renewable, infinitely recyclable plastics using bacteria



Scientists engineered microbes to make the ingredients for recyclable plastics -- replacing finite, polluting petrochemicals with sustainable alternatives. The new approach shows that renewable, recyclable plastics are not only possible, but also outperform those from petrochemicals.
Published New study reveals that tree species diversity increases spider density



The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published New insights into the origin of the Indo-European languages



An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published New research method determines health impacts of heat and air quality



The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Using cosmic weather to study which worlds could support life


As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets.
Published Webb snaps highly detailed infrared image of actively forming stars



Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.
Published Climate change threatens 771 endangered plant and lichen species



All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.
Published New planetary formation findings


Astronomers have discovered new evidence of how planets as massive as Jupiter can form.
Published Delaying methane mitigation increases risk of breaching Paris Agreement climate goal, study finds



A new study shows that efforts to reduce methane emissions are needed immediately if we are to meet global climate change goals. A key element of the 2015 Paris Agreement, a legally binding international treaty on climate change, is the commitment to limit average global temperatures increases to well below 2°C above pre-industrial levels, and pursue efforts to limit global warming to 1.5°C above pre-industrial levels. This requires reaching net-zero CO2 emissions by or around 2050 -- and deep reductions in methane and other emissions.
Published Astronomers reveal new features of galactic black holes


An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.
Published Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'



About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.
