In a novel study comparing healthy cells from people in their 20s with cells from people in their 80s, researchers say they have documented that cell division rates appear to consistently and markedly slow down in humans at older ages.
Read moreA phase 2 clinical trial using a new technology show it is possible to induce immune tolerance to gluten in individuals with celiac disease. After treatment with the technology, the patients were able to eat gluten with a substantial reduction in inflammation.
Read moreBiologists report that they have recorded the loudest bird calls ever documented, made by dove-sized male white bellbirds as part of their mating rituals in the mountains of the northern Amazon.
Read moreWhile studying sediments in the Bay of Bengal, an international team finds evidence dating back millions of years that catastrophic events likely toppled fresh trees from their mountain homes on a long journey to the deep sea. The discovery may add to models of the Earth's carbon cycle.
Read moreAn international team of scientists has discovered that some of the most renowned classic Belgian beers, including Gueuze and Trappist ales, are fermented with a rare and unusual form of hybrid yeasts. These yeasts combine DNA of the traditional ale yeast, Saccharomyces cerevisiae, with that of more stress-resistant feral yeasts such as Saccharomyces kudriavzevii.
Read moreFound as an ingredient in many processed and packaged foods, palm oil is the most widely consumed vegetable oil. Now, researchers have discovered an unlikely ally for palm oil production: pig-tailed macaques.
Read moreOur brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today's discovery helps to solve a long-standing scientific question as to how the brain's listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain.
Read moreDespite an overall increase in the number of pharmacies in the U.S. from 2009 to 2015, one in eight pharmacies, or 9,654, had closed during this period. Independent pharmacies in both urban and rural areas were three times more likely to close than chain pharmacies.
Read moreThe transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.
Read moreNew research, based on 33 historical El Niño events from 1901 to 2017, show climate change effects have shifted the El Niño onset location from the eastern Pacific to the western Pacific and caused more frequent extreme El Niño events since the 1970's. Continued warming over the western Pacific warm pool, driven by anthropogenic climate change, promises conditions that will trigger more extreme events in the future.
