In recent years, ultrasmall metal nanoclusters have unlocked advances in fields ranging from bioimaging and biosensing to biotherapy, thanks to their unique molecular-like properties.

Lessons learned from the COVID-19 pandemic that can improve the lives of Americans are still ongoing, thanks to the help and insight of UNM's Center for Social Policy (CSP.)

Modeling is a dream occupation for many young women, but for those who make modeling a career, finding work can be a traumatic, sexualized nightmare, a Rutgers University-New Brunswick study finds.

Macroalgae are the most productive plants in coastal ecosystems. They have attracted worldwide interest due to their ability to sequester carbon. The growth of macroalgae can produce significant amounts of particulate organic carbon (POC), but it is unclear how these POC are metabolized and how they affect carbon sequestration.

An international team of scientists provide an overview of the latest research on light-matter interactions. A team of scientists from the Fritz Haber Institute, the City University of New York, and the Universidad de Oviedo has published a comprehensive review article in Nature Reviews Materials. This article provides an overview of the latest research on polaritons, tiny particles that arise when light and material interact in a unique way.

When you go running in the woods in your running tights, elastane is the reason they fit you so comfortably. Elastane is an elastic material that allows the fabric to stretch and adapt to your body.

Migration is an increasingly dominating topic in politics and is discussed with increasing vehemence among the German population. Those in favor of migration say that the lack of skilled workers and shortage of staff will become worse without immigration. Those who oppose migration fear that an increasing number of immigrants will exceed the reception capacities of the country.

A total of 90% of the municipal textile waste generated in Catalonia ends up in landfills or incinerators, according to a study by ICTA-UAB, which shows that only 10% of textile waste is collected separately. In the case of Catalonia, this percentage represented the management of 18,630 tons of clothing and other textile materials in 2020.

Before planets form around a young star, the protosolar disk is populated with innumerable planetesimals. Over time, these planetesimals combine to form planets, and the core accretion theory explains how that happens. But before there are planets, the disk full of planetesimals is a messy place.

There are many different ways to get to Mars, but there are always tradeoffs. Chemical propulsion, proven the most popular, can quickly get a spacecraft to the red planet. But they come at a high cost of bringing their fuel, thereby increasing the mission's overall cost. Alternative propulsion technologies have been gaining traction in several deep space applications. Now, a team of scientists from Spain has preliminary studied what it would take to send a probe to Mars using entirely electric propulsion once it leaves Earth.

A recent study published in Big Earth Data has shown how scientists from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) harnessed satellite altimetry to track changes in the water level of 988 Chinese lakes larger than 10 square kilometers.

Research by Petaluma-based non-profit, Point Blue Conservation Science, shows how Adélie penguins within the Ross Sea, Antarctica use sea ice in their annual migrations. The paper, "Going with the floe: Sea‐ice movement affects distance and destination during Adélie penguin winter movements," is published in the journal Ecology.

When scientists detected phosphine in Venus' atmosphere in 2020, it triggered renewed, animated discussions about Venus and its potential habitability. It would be weird if the detection didn't generate interest since phosphine is a potential biomarker. So people were understandably curious. Unfortunately, further study couldn't confirm its presence.

Soil acidification is widely occurring in diverse terrestrial ecosystems and soil microbial communities have been reported to be highly sensitive to changes in soil pH. Soil microbes could regulate their physiological conditions to make them survive under the acidifying conditions.

Astronomers have completed the largest and most detailed study of what triggers stars to form in the universe's biggest galaxies, using NASA's Chandra X-ray Observatory and other telescopes. They were surprised to find that the conditions for stellar conception in these exceptionally massive galaxies have not changed over the last ten billion years.

Ethylene is sometimes called the most important chemical in the petrochemical industry because it serves as the feedstock for a huge range of everyday products. It's used to produce antifreeze, vinyl, synthetic rubber, foam insulation, and plastics of all kinds.

Mange is a skin disease that can compromise a pet's well-being, leading to discomfort and potential health complications. Though it is a more common condition for dogs, cats can also be at risk, which is why owners should familiarize themselves with common varieties of feline mange.

Picky female sparrows may be more unfaithful, new Imperial research suggests. Cheating on social partners is common in birds, and there are clear benefits to males who can raise more offspring without investing in their care. For females, however, the drivers are less obvious.

Extreme rainfall events are becoming more extreme and periods of drought are becoming more frequent. To keep the Dutch delta livable, adaptations will be needed, such as extra water buffers. The Netherlands has a long history of struggle against water, but also makes eager use of it. What can we learn from our heritage?

Many organisms can produce minerals or mineralized tissue. A well-known example is nacre, which is used in jewelry because of its iridescent colors. Chemically speaking, its formation begins with a mollusk extracting calcium and carbonate ions from water. However, the exact processes and conditions that lead to nacre, a composite of biopolymers and platelets of crystalline calcium carbonate, are the subject of intense debate among experts, and different theories exist.

By one estimate, as many as 30% of people in the U.S. are in romantic relationships with partners who do not share their political views. In today's hyperpartisan climate, where Democrats and Republicans have difficulty talking to each other and their views are polarized about media outlets' credibility, how do couples with differing political perspectives decide which media to follow? And how do these decisions affect their discussions on political issues and their relationship in general?

A critically endangered parrot, with a population numbering as few as 70 in the wild, could be at further risk after being found to carry a half-dozen previously undetected viruses.

It's no secret human activity is warming the planet, driving more frequent and intense extreme weather events and transforming ecosystems at an extraordinary rate.

The recent firing and rapid rehiring of Sam Altman, the co-founder and CEO of ChatGPT creator OpenAI, illustrates the delicate dance between visionary CEOs and the boards who oversee them.

If you happened to be looking at the sky in Europe on a cold night on February 5, 1993, there is a chance you could have seen a dim flash of light. That flash came from a Russian space mirror experiment called Znamya-2.
