Mesenchymal stem cells (MSCs) are thought to have great potential in the field of regenerative medicine, which has the aim of restoring damaged tissues. However, not much was known about in vivo plasticity of them—until now. Researchers have identified a subpopulation of MSCs that promote the healing of bone fractures and show an enhanced ability […]
Nicotine ingested from smoking exerts neuroprotection and developmental neurotoxicity in the central nervous system. It can produce changes of cognitive behaviors through regulating the release of different neurotransmitters in the brain. However, the effects of nicotine exposure or withdrawal on neurotransmitter metabolism of hippocampal neurons still remain unclear. Dr. Luo Qian’s group from the Shenzhen […]
A team of South Dakota State University chemistry researchers uncovered how cancer cells utilize a simple sugar residue to disguise themselves from the immune system. What they learned will help scientists develop more effective cancer therapeutics. “We utilized the lens of organic chemistry to understand how cancer cells evade the immune system,” explained assistant chemistry […]
A study involving Te Herenga Waka—Victoria University of Wellington’s Dr. Denise Taylor and led by Associate Professor Susan Wells from the University of Auckland calls for separate stroke and heart attack risk predictors to improve understanding of those at risk. Separate risk equations are needed to help older people better understand how to lower their […]
A clinical trial now enrolling at the University of Alabama at Birmingham is taking an unusual approach to help patients with Type 2 diabetes. Instead of medications, the study is using diet alone to improve blood sugar control and remodel the body “by re-partitioning energy away from metabolically harmful lipid stores,” said Barbara Gower, Ph.D., […]
Yi “Edwin” Sun, a Ph.D. candidate in electrical and computer engineering at the University of Illinois Urbana-Champaign and member of the Beckman Institute’s Biophotonics Imaging Laboratory headed by Stephen Boppart, explored how deep learning methods can make polarization-sensitive optical coherence tomography, or PS-OCT, more cost-effective and better equipped to diagnose cancer in biological tissues. The […]
Researchers at NYU Abu Dhabi (NYUAD), in collaboration with Global TIES for Children and researchers at University of California Davis (Paul Hastings and Lindsey Partington) as well as Hashemite University in Jordan (Rana Dajani), have used a hair cortisol test to detect the impact of COVID-19 on stress levels in families. Titled “Adrenocortical and psychosocial […]
Researchers at Monash University have established one of the world’s largest collections of living tumors from prostate cancer patients, accelerating the testing of new treatments for prostate cancer and leading to faster patient benefit. One of the most common cancers, prostate cancer is also one of the most difficult to study in the laboratory, with […]
Researchers from the University of Birmingham, U.K., have confirmed the speed, accuracy and simplicity of a novel, highly sensitive testing method for COVID-19 that can be deployed at entertainment venues, airport arrival terminals, and in remote settings where clinical testing laboratories are not available. The scientists used a three way comparison study to confirm that […]
A joint team from the Russian Quantum Center, Skoltech, and the Higher School of Economics has presented a novel supersensitive solid-state magnetometer operating at room temperature. The researchers for the first time used it to detect and record brain electrical activity with a technique called magnetoencephalography, which could become dozens of times cheaper with the […]
