Experiments simulate possible impact of climate change on crabs
Fewer Atlantic mangrove fiddler crab embryos survived in a warmer, more acid environment mimicking conditions forecast for the end of this century. Given the important ecological role of this invertebrate in mangroves, the researchers warn of a potential cascade effect.

Scientists discover how oxygen loss saps a lithium-ion battery's voltage
SLAC and Stanford scientists took a unique and detailed nanoscale look at how oxygen seeps out of lithium-ion battery electrodes, sapping their energy over time. The results could suggest a fix.

Communication technology, study of collective behavior must be 'crisis discipline'
Social media and other forms of communication technology restructure these interactions in ways that have consequences. Unfortunately, we have little insight into whether these changes will bring about a healthy, sustainable and equitable world. As a result, researchers now say that the study of collective behavior must rise to a "crisis discipline," just like medicine, conservation and climate science have done, according to a new paper published June 14 in the Proceedings of the National Academy of Sciences.

Does zinc inhibit or promote growth of kidney stones? Well, both
In the first study to validate conflicting theories, a University of Houston researcher has confirmed that the zinc actually does inhibit and promote the growth of kidney stones at the same time.

Harmful protein waste in the muscle
An international research team identified the cause of a rare muscle disease. According to these findings, a single spontaneously occurring mutation results in the muscle cells no longer being able to correctly break down defective proteins. The condition causes severe heart failure in children, accompanied by skeletal and respiratory muscle damage. The study also highlights experimental approaches for potential treatment. Whether this hope will be fulfilled, however, will only become clear in a few years.

Dark matter is slowing the spin of the Milky Way's galactic bar
For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured.The researchers say it gives a new type of insight into the nature of dark matter, which acts like a counterweight slowing the spin.

New combination of materials provides progress toward quantum computing
In research published today in Nature Communications, engineers from Rensselaer Polytechnic Institute demonstrated how, when the TMDC materials they make are stacked in a particular geometry, the interaction that occurs between particles gives researchers more control over the devices' properties. Specifically, the interaction between electrons becomes so strong that they form a new structure known as a correlated insulating state. This is an important step, researchers said, toward developing quantum emitters needed for future quantum simulation and computing.

COVID-19 creates conditions for emergence of 'superfungus' in Brazil
The presence of Candida auris in a hospital in Salvador, Bahia, was confirmed at end-2020 and reported in an article in the Journal of Fungi. The fungus can cause a lethal invasive disease and is ringing alarm bells because of the speed with which it develops drug resistance.

Study reveals COVID-19 risk factors for those with IDD
A study of nearly 550 adults with intellectual and developmental disabilities receiving residential services in New York City found that age, larger residential settings, Down syndrome and chronic kidney disease were the most common risk factors for COVID-19 diagnosis, and heart disease was most associated with COVID-19 deaths.

Women leaving jail have high vaccine hesitancy; app drops resistance, boosts literacy
Researchers at the University of Kansas found high vaccine hesitancy among women leaving incarceration, a substantial and vulnerable population in the United States. However, a web-based health app proved effective at boosting the group's health literacy.

Pollutant concentration increases in the franciscana dolphin
The concentration of potentially toxic metals is increasing in the population of the franciscana dolphin --a small cetacean, endemic from the Rio de la Plata and an endangered species-- according to a study led by a team of the Faculty of Biology and the Biodiversity Research Institute (IRBio), published in the journal Science of The Total Environment.

Biodiversity 'hotspots' imperiled along California's streams
A study of woodland ecosystems that provide habitat for rare, endangered species along streams, rivers throughout California reveals some ecologically important areas are inadvertently benefitting from water humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended dependence on its bounty, threatens the long-term survival of natural communities and spotlights the need for changes in the way water is managed across the state.

Model suggests surgery should precede chemotherapy for select patients with ovarian cancer
Certain patients with an aggressive form of ovarian cancer have a better chance of a cure through surgical removal of their tumor before chemotherapy instead of the reverse, a new study shows.

Toxin-adapted fish pass down epigenetic mutations to freshwater offspring
Researchers analyzed the epigenetics--molecular factors and processes that determine whether genes are turned on or off--of a group of Poecilia mexicana fish that live in springs naturally high in hydrogen sulfide, which is normally toxic to most organisms. Even after raising samples of fish in freshwater, researchers found that grandchildren of sulfidic-adapted fish had more epigenetic marks in common with their wild, toxic-water-living grandparents than Poecilia mexicana that had always lived in freshwater.

UM research: Rocky mountain forests now burning more than any point in past 2,000 years
Following 2020's extreme fire season, high-elevation forests in the central Rocky Mountains now are burning more than at any point in the past 2,000 years, according to a new University of Montana study recently published in the Proceedings of the National Academy of Sciences.
