The pre-human “Lucy” either lived in trees or at least spent a lot of time in trees, a new analysis of the little hominid’s skeleton suggested.
A tem of researchers from that Johns Hopkins University and University of Texas conducted scans of Lucy’s skeleton, a more than three million years old fossil that is also known as AL 288-1. Bone scans showed that Lucy’s upper arms had been thicker and stronger than her thigh bones. The same pattern is found in chimpanzees.

The Great Barrier Reef in Australia suffered its worst coral die-off this year as warmer seas killed more than two-thirds of a 700-kilometer (435 miles) stretch of coral within the last nine-month period, researchers announced on Monday.
The Australian Research Council’s Centre of Excellence for Coral Reef Studies said in its latest report that the reef’s northern region, off the coast of Queensland, Australia, suffered a loss of 67 per cent of its shallow-water corals during the last eight to nine months.
Higher ocean temperatures melted Pine Island Glacier from underneath and caused a deep subsurface crack, causing a massive iceberg to splint off one of Antarctica's largest glaciers in 2015, according to a new study by Ohio State University (OSU) researchers.
Led by Ian Howat, an associate professor of Earth sciences at OSU, the researchers discovered that warmer waters caused a 20-mile-long subsurface rift that eventually cleaved off a 225-square-mile iceberg in July last year.

The pinching force of an adult coconut crab is almost equal to the deadly bite force of an adult lion, according to a study published in the journal PLOS ONE.
The so-called coconut crabs (Birgus latro), which inhabit islands in the Indian and southern Pacific oceans can grow up to 9 pounds in weight, with a leg-span of 3 feet. These large crabs can easily crack open the hard shells of coconuts.

The U.S. Food & Drug Administration has confirmed that Sabra Dipping Co. has issued a voluntary recall for some of its hummus products after food inspectors detected potential listeria contamination risk.
Listeria infection causes serious and sometimes fatal infections, particularly in kids, old people, and others with undermined immune systems. The long list of symptoms includes muscle aches, stiffness, fever, diarrhea and abdominal pain.

U.S. Surgeon General Vivek Murthy’s newly released report, titled “Facing Addiction in America,” outlines bleak terms of the severity of the issue.
The report on the nation’s drug and alcohol addiction crisis states that more than 500,000 U.S. citizens have died from drug or alcohol abuse since 2000, and as many as 21 million people are in the grip of substance abuse disorders, yet only 10 per cent of them are getting treatment.

Scientists are trying to map the infinite cosmos using a mysterious powerful burst of radio waves that are coming from an unknown distant source.
The so-called fast radio bursts or brilliant flashes have been captured by multiple telescopes on our planet. While no two flashes are the same, they all burst with seemingly intense amounts of energy every few seconds.

The biggest question for couples who undergo in-vitro fertilization (IVF) is how successful the treatment will be. To help such couples, a team of researchers has developed a new online calculator that can provide a better idea of their IVF success even before they embark on their first cycle.
The researchers, led by David McLernon of University of Aberdeen, reported that their online calculator is based on data collected from more than 113,000 IVF users, and that it can efficiently help couples find out their chances of having a baby over multiple cycles of IVF treatment.
