NEW YORK, NY--Far-UVC light is a promising new technology for reducing airborne virus levels in occupied indoor spaces, but its effectiveness has not been evaluated in real-life scenarios.  A new study by Columbia researchers now shows that far-UVC light inactivated nearly all (>99%) of an airborne virus in an occupied work environment, showing that the technology can work as well in a real-life scenario as in the laboratory.  “The results show that far-UVC is highly effective at reducing airborne pathogens in an ordinary occupied room, and so it’s practical to use far-UVC light in indoor areas where people are going about their business,” says David ...

Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate change, in addition to being vital to soil health and agricultural productivity. Measuring soil carbon, however, is a painstaking, expensive process. Samples must be dug from the ground and sent to a lab for analysis, making upscaling measurements on a large spatial scale ...

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun’s angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.   “The angle between the sunshine and your window is always changing,” said Tengfei Luo, the Dorini Family Professor for Energy Studies at the University of Notre ...

Researchers in Brazil have used an innovative technique in molecular biology to identify targets for candidate vaccines against Schistosoma mansoni, the parasite that causes schistosomiasis. Considered one of the world’s 17 neglected tropical diseases (NTDs), schistosomiasis affects some 200 million people in 74 countries, according to the World Health Organization (WHO). Six million are estimated to be infected in Brazil, mainly in the Northeast region and Minas Gerais state. The scientists used phage display, the study of protein interactions using bacteriophages, viruses that infect bacteria, to screen 99.6% of 119,747 DNA sequences encoding the proteins known ...

UCalgary led study finds Netflix misses the mark by trivializing teenagers’ pain. Findings are published in PainResearchers at the University of Calgary and the University of Bath, U.K., are calling on Netflix to do a better job of representing the kind of pain typically experienced by 12-to-18-year-olds. A new study finds the streaming channel should not emphasize stereotypes, like the heroic, stoic boy and the helpless, emotional girl who requires his rescue and prioritizes his pain and suffering. “Media ...

A pioneering study from the University of Florida has quantified corporations’ exposure to climate change risks like hurricanes, wildfires, and climate-related regulations and the extent to which climate risks are priced into their market valuations. The research also exposes a costly divide – companies that proactively manage climate risks fare much better than those that ignore the threats. Using textual analysis of earnings call transcripts from almost 5,000 U.S. public companies, researchers developed novel measures of firms’ physical climate risk exposure ...

Scrub mints are among the most endangered plants you’ve probably never heard of. More than half of the 24 species currently known to exist are considered threatened or endangered at the state or federal level, and nearly all scrub mints grow in areas that are being rapidly developed or converted to agricultural pasture. In a new study, researchers analyzed a distinct type of DNA marker, which shows there are likely more scrub mint species waiting to be scientifically described. And at least one species has been left without federal protection because of a technicality. “The Titusville balm is currently considered ...

Plants harness chlorophyll to capture sunlight and kickstart photosynthesis, a crucial process on our planet that converts luminous energy into chemical fuel while producing oxygen. This pivotal chemical energy is subsequently utilized by plants, algae, and select bacteria to metabolize carbon dioxide and water into sugars. Now, scientists at the Center for Research in Biological Chemistry and Molecular Materials (CiQUS) have achieved a breakthrough by integrating non-native photosensitizers into mammalian cells. This revelation showcases the capability of these substances to also absorb green ...

Owning a home has long been considered a crucial way to build wealth, but making such a purchase has become increasingly difficult for many residents. In addition to steep housing prices and high interest rates, there have been a growing number of all-cash buyers who can close a deal quickly, beating out competing offers from buyers who need to finance their home with a mortgage. The convenience and certainty of all-cash offers appeals to sellers so much so, that they pay on average 10 % less than mortgage buyers, according to a new study from the University of California San Diego Rady School of Management. “When sellers accept a mortgage offer, it comes with risk,” said Michael ...

Infant gut microbiomes oscillate with a circadian rhythm, even when they are cultivated outside of the body. Researchers report April 2 in the journal Cell Host & Microbe that the rhythm is detectable as early as 2 weeks after birth but becomes more pronounced with age. The finding comes from a randomized controlled trial that also showed that diet has less impact on the development and composition of the infant microbiome than previously thought. “We found that even at very early ages of colonization, the microbial ecosystem develops this circadian rhythmicity,” ...

ROCHESTER, Minn. — A new multicenter, international study suggests that people who have early-stage triple-negative breast cancer (TNBC) and high levels of immune cells within their tumors may have a lower risk of recurrence and better survival rates even when not treated with chemotherapy. The study was published in the Journal of American Medical Association (JAMA). TNBC is a breast cancer subtype that does not respond to drugs that target the estrogen receptor or the HER2 protein. It grows rapidly, is more likely to spread beyond the breast before diagnosis ...

Fukuoka, Japan—Researchers from Kyushu University's Faculty of Medical Sciences report on new insights into the mechanisms of how adrenal gland tumors are formed. The team identified a new type of tumor cell population that they termed 'steroids-producing nodules' or SPNs, that exhibits the unique characteristic of producing two different hormones. Specific structures in SPNs were found to lead to cortisol-producing adenomas, or CPAs, noncancerous tumors that produce excessive cortisol. Their findings, published in eBioMedicine, ...
