The sea slug, Elysia chlorotica, is able to become plant like and survive just on photosynthesis. The slug steals millions of green-colored plastids, which are like tiny solar panels, from the non-toxic brown alga, store them in their gut lining - to become photosynthetic, or solar-powered.
Thinking that the earth might be flat appears to have grown in popularity in recent years. Indeed, flat earthers are gathering for their annual conference this year in Birmingham, just two miles from my own university. But the earth isn’t flat. Unsurprisingly, this isn’t hard to prove. But as scads of YouTube videos demonstrate, these proofs fail to convince everyone. A glance at the comments show there’s still vitriolic disagreement in some quarters.
The European Space Agency (ESA) has released the most comprehensive map of our Milky Way Galaxy. The map, which is based on the latest data from the ESA's Gaia mission, includes the positions, distances and motions of nearly 1.7 billion stars, as well as asteroids within our Solar System.
In a first, researchers at Garvan Institute of Medical Research, Australia have identified a new DNA structure inside living human cells. Known as the intercalated motif (i-Motif), the newly identified structure looks poles apart from the iconic double helix structure everyone associates with DNA.
Muscular strength, measured by handgrip, is an indication of how sharp your brain is. The study which involved nearly half a million people also showed that the relationships were consistently strong in both people who were under the age of 55 and those over 55.
Study has found that the narrow diamond needles, could flex and stretch by as much as 9 percent without any breakage, then snap back to their original shape – much like rubber.
Stephen Hawking, one of the greatest theoretical physicists, has died at his home in Cambridge. He was 76. At the age of 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS), a rare neurodegenerative disease commonly known as Lou Gehrig's Disease. It left him wheelchair-bound and totally paralyzed.
Researchers at Yale University in New Haven, CT, have discovered that intestinal bacteria in mice and humans can travel to other organs and evoke autoimmune response. But, administering antibiotic or vaccine that targets the bacteria can subdue this autoimmune reaction.
A gene is a segment of DNA that contains a set of instructions to make molecules that organisms need to survive. In a process called gene expression, these instructions are converted into some sort of product. And the product usually is either a protein or functional RNA. So what is gene expression? And, how do genes express themselves?
