Turncoat T cells are at the core of multiple sclerosis and other inflammatory central nervous system disorders

Intriguing new research has pinpointed a special population of T cells—tissue-resident memory T cells—as key players in the development of chronic autoimmune disorders that affect the central nervous system, opening a ...

Scientists engineer synthetic DNA to study 'architect' genes

Researchers at New York University have created artificial Hox genes—which plan and direct where cells go to develop tissues or organs—using new synthetic DNA technology and genomic engineering in stem cells.

Dissolving implantable device relieves pain without drugs

A Northwestern University-led team of researchers has developed a small, soft, flexible implant that relieves pain on demand and without the use of drugs. The first-of-its-kind device could provide a much-needed alternative ...

Breaking AIs to make them better

Pandas gave bamboo the thumbs up at least six million years ago

When is a thumb not a thumb? When it's an elongated wrist bone of the giant panda used to grasp bamboo. Through its long evolutionary history, the panda's hand has never developed a truly opposable thumb and instead evolved ...

Emu software uses common gene to profile microbial communities

Part of a gene is better than none when identifying a species of microbe. But for Rice University computer scientists, part was not nearly enough in their pursuit of a program to identify all the species in a microbiome.

Researchers discover new leukemia-killing compounds

Researchers from Rice University and the University of Texas MD Anderson Cancer Center have discovered potential new drugs that work in concert with other drugs to deliver a deadly one-two punch to leukemia.

Breaking AIs to make them better

Today's artificial intelligence systems used for image recognition are incredibly powerful with massive potential for commercial applications. Nonetheless, current artificial neural networks—the deep learning algorithms ...

A gentler, more precise laser cutting technique

Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University have developed a gentler, more precise technique using low-power visible light.

How COVID-19 put poverty reduction back on the agenda

Lower income people bore the brunt of the economic repercussions of the COVID-19 pandemic. As a result, efforts to reduce poverty were adopted in Canada and the United States. But how did partisan politics shape each government's ...

Comparative analyses of American and Asian lotus genomes

Nelumbo is a unique genus of Nelumbonaceae (lotus), which comprises two extant species: N. nucifera Gaertn. widely distributed in Asia and northern Australia, and N. lutea Pers. which is distributed in America. These two ...

New flood maps clarify the risk homeowners face

Flooding in urban areas cost Americans more than $106 billion between 1960 and 2016, damaging property, disrupting businesses and claiming lives in the process. Determining which areas are most likely to flood amid ever-changing ...

Leaders must deliver 'strong' ocean treaties: Greenpeace

Governments must adopt strong, enforceable treaties to protect oceans affected by global warming, overfishing and rampant pollution, Greenpeace activists said while staging a protest Thursday at the UN Ocean Conference in ...
