The same cell types that cause goosebumps are responsible for controlling hair growth. If you’ve ever wondered why we get goosebumps, you’re in good company — so did Charles Darwin, who mused about them in his writings on evolution. Goosebumps might protect animals with thick fur from the cold, but we humans don’t seem to benefit from the reaction much — so why has it been preserved during evolution all this time?

In a new study, Harvard University scientists have discovered the reason: the cell types that cause goosebumps are also important for regulating the stem cells that regenerate the hair follicle and hair...

The device could be used in sign language translation, VR, mobile health, human-robot interaction and and more. The bracelet, called FingerTrak, can sense and translate into 3D the many positions of the human hand, including 20 finger joint positions, using three or four miniature, low-resolution thermal cameras that read contours on the wrist.

“This was a major discovery by our team — that by looking at your wrist contours, the technology could reconstruct in 3D, with keen accuracy, where your fingers are,” said Cheng Zhang, assistant professor of information science and director of Cornell’s new SciFi Lab, where FingerTrak was developed...

New 3D model provides evidence that Venus is churning inside. A new study identified 37 recently active volcanic structures on Venus. The study provides some of the best evidence yet that Venus is still a geologically active planet. A research paper on the work, which was conducted by researchers at the University of Maryland and the Institute of Geophysics at ETH Zurich, Switzerland, was published in the journal Nature Geoscience on July 20, 2020.

“This is the first time we are able to point to specific structures and say ‘Look, this is not an ancient volcano but one that is active today, dormant perhaps, but not dead,'” said Laurent Montési, a professor of...

Researchers at the University of Arkansas have developed a new nano drug candidate that kills triple negative breast cancer cells. Triple negative breast cancer is one of the most aggressive and fatal types of breast cancer. The research will help clinicians target breast cancer cells directly, while avoiding the adverse, toxic side effects of chemotherapy.

Their study was published in June issue of Advanced Therapeutics.

Researchers led by Hassan Beyzavi, assistant professor in the Department of Chemistry and Biochemistry, linked a new class of nanomaterials, called metal-organic frameworks, with the ligands of an already-developed photodynamic therapy dru...
