Data from Parker Solar Probe helps unravel sun’s mysteries

Science
Dec. 4 (UPI) -- Over the last year, NASA's Parker Solar Probe flew closer to the sun than any previous spacecraft. Now, scientists are beginning to make sense of the measurements captured by the probe's four instruments during its first three record-setting flybys. On Wednesday, researchers published four new scientific papers, all supported by Parker Solar Probe data, in the journal Nature. According to the authors of the new studies, the observations and measurements recorded by the Parker Solar Probe are bringing scientists closer to solving some of the sun's greatest mysteries -- like explaining why the corona is a couple million degrees hotter than the sun's surface, where solar flares come from and what propels solar wind. "Some of the data confirmed what we already thought, but so...
Dual motion helps cells keep their shape

Dual motion helps cells keep their shape

Science
Nov. 26 (UPI) -- To keep their shape, cells rely on two different types of motion, according to a new study. The discovery -- detailed this week in the journal eLife -- promises new insights into the biomechanics of cellular health, insights that could reveal the origins of disease. "Nucleolar malfunction can lead to disease, including cancer," senior study author Alexandra Zidovska, an assistant professor of physics at New York University, said in a news release. "Thus, understanding the processes responsible for the maintenance of nucleolar shape and motion might help in the creation of new diagnostics and therapies for certain human afflictions." Until now, scientists weren't sure how cellular components without membranes keep their shape. The latest research revealed a unique dual mo...
Mothering poison frog in Madagascar helps scientists study the maternal brain

Mothering poison frog in Madagascar helps scientists study the maternal brain

Science
Nov. 22 (UPI) -- Most frogs lay dozens of eggs and leave. The tadpoles-to-be are on their own from the start. In a new study, scientists examined why some frog moms stick around to help raise their young. At least two species, including Madagascar's climbing mantella, a poison frog species, are much more nurturing and attentive than the average frog mom. Both the climbing mantella and Ecuador's little devil frog lay just a few eggs in pools of water that collect in cupped leaves. The moms sit next to their offspring and feed the growing tadpoles' unfertilized eggs until they're big enough to venture off on their own. New research, published this week in the journal Current Biology, suggests the extra motherly attention helps the young frogs develop potent chemical defenses. When scientis...
Switch to vaping ‘helps smokers’ hearts’

Switch to vaping ‘helps smokers’ hearts’

Health
Smokers can improve the health of their hearts within weeks of switching to e-cigarettes, the largest trial of its kind shows. The month-long study of 114 smokers suggests vaping has the potential to reduce heart attack and stroke risk. The team, at the University of Dundee, stressed vaping was "not safe" - just less harmful than tobacco.The British Heart Foundation said stopping smoking was the single best thing you could do for your heart. Chemicals in cigarette smoke narrow arteries as they get furred up with fatty deposits increasing the risk of a deadly blockage. Ultimately smoking doubles your risk of having a heart attack. But the researchers said the current evidence on vaping was "very poor" and often assessed the impact o...
