In a vacuum like space, the speed of light is just over 186,280 miles per second. Scientists have now shown it’s possible to slow it down to zero miles per second without sacrificing its brightness, regardless of its frequency or bandwidth.

Scripps Research scientists have developed an antibody that can block the effects of lethal toxins in the venoms of a wide variety of snakes found throughout Africa, Asia and Australia.
The antibody, which protected mice from the normally deadly venom of snakes including black mambas and king cobras, is described in Science Translational Medicine. The new research used forms of the toxins produced in the laboratory to screen billions of different human antibodies and identify one that can block the toxins’ activity. It represents a large step toward a universal antivenom that would be effective against the venom of all snakes.
“This antibody works against one of the major toxins found across numerous snake species that contribute to tens of thousands of deaths every year,” says senior author Joseph Jardine, Ph.D., assistant professor of immunology and microbiology at Scripps Research. “This could be incredibly valuable for people in low-and middle-income countries that have the largest burden of deaths and injuries from snakebites.”

We all travel through space time at speed of light. But, what does it really mean? How does it explain the consequences of special relativity — time dilation, length contraction, relativity of simultaneity, and more.

Since 1931, science fiction has speculated on how microbots might work and how they will change our lives.
People often believe what they want to believe rather than what the evidence implies. Here Melnikoff and Strohminger find that this seemingly irrational tendency may emerge from fully rational Bayesian calculations.
A team of researchers has found that Neanderthals crafted stone tools using a sophisticated multi-component glue. This discovery, the oldest known example of such an advanced adhesive in Europe, indicates that these early human relatives possessed a greater degree of intellectual and cultural sophistication than was earlier believed.
The work, reported in the journal Science Advances, included researchers from New York University, the University of Tübingen, and the National Museums in Berlin.
