ALMA scientists detect signs of water in a galaxy far, far away: New study marks most distant detection of required element for life as we know it in a regular star-forming galaxy
Water has been detected in the most massive galaxy in the early Universe, according to new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Scientists studying SPT0311-58 found H20, along with carbon monoxide in the galaxy, which is located nearly 12.88 billion light years from Earth. Detection of these two molecules in abundance suggests that […]
Three ways to reduce the carbon footprint of food purchased by US households
Most consumers want to make food purchases that are smart for their wallets, their health and the environment. And while switching to a vegetarian or vegan diet can lower one’s impact on greenhouse gas emissions, it may not be realistic or healthful for everyone. Now, researchers in ACS’ Environmental Science & Technology report three ways […]
Roman noblewoman’s tomb reveals secrets of ancient concrete resilience: Study shows how changing chemistry in Roman mortar strengthens the tomb over time
Over time, concrete cracks and crumbles. Well, most concrete cracks and crumbles. Structures built in ancient Rome are still standing, exhibiting remarkable durability despite conditions that would devastate modern concrete. One of these structures is the large cylindrical tomb of first-century noblewoman Caecilia Metella. New research shows that the quality of the concrete of her […]
What Causes Pneumonic Plague?
Pneumonic plague is the most dangerous type of plague caused by Yersinia pestis (Y pestis) and occurs when the bacterium infects the lungs Pneumonic plague is the most dangerous type of plague caused by Yersinia pestis (Y pestis) and occurs when the bacterium infects the lungs. The disease can spread through the air from person […]
Reducing salt in bread without sacrificing taste
Most people in the U.S. consume too much salt; adult Americans typically eat twice the daily amount recommended by dietary guidelines. Bread may not seem like an obvious culprit; however, due to high consumption and relatively high salt content, baked goods are a major source of sodium in the diet. A new study from the […]
Geologically vibrant continents produce higher biodiversity
Tropical rainforests are the most biodiverse habitats on Earth. They are home to a huge number of different plants, animals, fungi and other organisms. These forests are primarily spread over three continents, concentrated in the Amazon Basin in South America, the Congo Basin in Central Africa, and the vast archipelago of Southeast Asia. One might […]
Researchers provide a framework to study precision nutrigeroscience
Dietary restriction is arguably the most promising non-genetic method of extending lifespan and healthspan in many model organisms, including mammals. While researchers scramble to develop interventions that would mimic the benefits of dietary restrictions in humans (who generally have a hard time maintaining Spartan diets), the work from the lab of Buck professor Pankaj Kapahi, […]
How Can Anger Hurt My Heart?
How to control your anger Recognizing and accepting your tendency to get angry is probably the first and most important step. If you find you’re often angry, it’s never too late to address it — there are many effective ways to control anger. Intense physical exercise Engaging in intense physical activity such as running, swimming, […]
COVID-19 antibodies persist, reduce reinfection risk for up to six months, study finds: The antibodies’ ability to neutralize COVID-19 did not differ significantly over the six-month period.
A Michigan Medicine study found that most patients with mild COVID-19 infections produce antibodies that persist and protect them from reinfection for up to six months. Researchers analyzed nearly 130 subjects with PCR-confirmed COVID-19 illness between three and six months after initial infection. Three patients were hospitalized while the rest were treated as outpatients and […]
Physical distance may not be enough to prevent viral aerosol exposure indoors: Architectural engineering team investigated the effects of physical distancing, building ventilation as control strategies
Eighteen months ago, stickers began to dot the floors of most shops, spaced about six feet apart, indicating the physical distance required to avoid the COVID-19 virus an infected person may shed when breathing or speaking. But is the distance enough to help avoid infectious aerosols? Not indoors, say researchers in the Penn State Department […]
