Exercise is one of the most important tools for staying healthy. It helps us to manage weight and improves cardiovascular and mental health. Exercise can also reduce our risk of certain diseases like diabetes and some cancers. The Centers for Disease Control and Prevention (CDC) recommends 150 minutes of moderate-intensity exercise each week, which amounts to about 30 minutes five days per week or 75 minutes of vigorous-intensity exercise weekly. This amounts to running or other vigorous forms ...read more
Want a flavorful beverage with a lot less lead? Try tea. According to a team of researchers from Northwestern University, tea leaves and bags adsorb lead, trapping lead ions on their surfaces and filtering them from drinking water during the process of tea brewing.“For this study, our goal was to measure tea’s ability to adsorb heavy metals,” said Vinayak Dravid, a member of the research team and a Northwestern professor, according to a press release. “By quantifying this effect, our wor ...read more
As far back as 22,000 years ago, humans may have improvised makeshift transportation tools that left grooves alongside their own footprints in what is now White Sands National Park in New Mexico. New research points to the travois — a device usually consisting of two poles joined together to carry a heavy load — as the source of these linear tracks, possibly representing the earliest evidence of transport technology used by humans. A research team surveyed the tracks in a study recently publ ...read more
The story of the red planet, it turns out, may be due for a revision. At one time, experts thought that Mars was covered with fields of rocks with iron trapped inside. Somehow or other, and over a long period, those rocks reacted to water in the air. That reaction formed rust, in much the same way it does when iron and water meet on Earth. Then, over billions of years, those rocks slowly eroded. As they broke down into dust, heavy winds spread the scarlet silty substance all around, until Mars ...read more
LTT 9779 b, an exoplanet 262 light years from Earth, always stares directly at the sun. With a surface of nearly 2000 degrees Celsius (about 3632 degrees Fahrenheit), the planet glows bright red while still reflecting starlight. Researchers have called it a rare ultra-hot Neptune.Thanks to images from the James Webb Space Telescope (JWST) published in Nature Astronomy, researchers are now able to see and analyze extreme weather patterns on this intriguing exoplanet, which can help them better un ...read more
