If dark energy is hiding in the form of hypothetical particles called “chameleons,” a team of researchers at the University of Pennsylvania and the University of California, Berkeley, plans to flush them out.
University of Pennsylvania researchers have made strides toward a new method of gene sequencing a strand of DNA’s bases are read as they are threaded through a nanoscopic hole.
In a new study, they have shown that this technique can also be applied to proteins as way to learn more about their structure.
The immune system not only responds to infections and other potentially problematic abnormalities in the body, it also contains a built-in brake in the form of regulatory T cells, or Tregs. Tregs ensure that inflammatory responses don’t get out of hand and do damage. In autoimmune diseases, sometimes these Treg cells don’t act as they should.
There is a theory that RNA, instead of DNA, is the original building block of all life. Yet many RNA molecules remain mysterious, their true nature and function little understood.
Big data sets are important tools of modern science. Mining for correlations between millions of pieces of information can reveal vital relationships or predict future outcomes, such as risk factors for a disease or structures of new chemical compounds.
At a rock outcropping in southern France, a jagged fracture runs along the granite. The surface in and around the crevice is discolored black, as if wet or covered in algae.
In small plastic tubs lining the shelves of a basement laboratory at the University of Pennsylvania, a million organisms live in complex societies.
Just as the brain forms memories of familiar faces, the immune system remembers pathogens it has encountered in the past. T cells with these memories circulate in the blood stream looking for sites of new infection.
