Whey protein supplements aren’t just for gym buffs according to new research from McMaster University. When taken on a regular basis, a combination of these and other ingredients in a ready-to-drink formula have been found to greatly improve the physical strength of a growing cohort: senior citizens.

The deterioration of muscle mass and strength that is a normal part of aging –known as sarcopenia—can increase the risk for falls, metabolic disorders and the need for assisted living, say researchers.

Coastal mangroves are among the most imperiled ecosystems on earth, with current estimates indicating that up to 67 per cent have been lost to date – according to the United Nations science wing.

“The stakes are high, because mangrove ecosystems provide benefits and services that are essential for life,” said Irina Bokova, Director-General of the UN Educational, Scientific and Cultural Organization (UNESCO) in a message on the International Day for the Conservation of the Mangrove Ecosystem.

Each time she looks through a microscope to better understand cave bacteria, Richenda McFarlane may also be staring at life that’s centuries old or perhaps even something from another planets.

She’s getting to play researcher, time traveler and astronaut all at the same time.

The world lost nearly 49 million acres of forest in 2015 to logging, wildfires, palm oil plantations, and other development activity, according to new data by the conservation group Global Forest Watch. That is equal to an area roughly the size of Nebraska, Climate Central reported. 

In recent years, perovskites have taken the solar cell industry by storm. They are cheap, easy to produce and very flexible in their applications. Their efficiency at converting light into electricity has grown faster than that of any other material – from under four percent in 2009 to over 20 percent in 2017 – and some experts believe that perovskites could eventually outperform the most common solar cell material, silicon. But despite their popularity, researchers don’t know why perovskites are so efficient.

Now experiments with a powerful “electron camera” at the Department of Energy’s SLAC National Accelerator Laboratory have discovered that light whirls atoms around in perovskites, potentially explaining the high efficiency of these next-generation solar cell materials and providing clues for making better ones.
