Cancer patients can lose salivary gland function during […]

When we are still embryos, proteins of the so-called “hedgehog” signaling pathway stimulate our cells to develop into different organs. When we are adults, this pathway falls largely silent, except in certain tissues that constantly regenerate themselves, for example our skin, and the linings of our blood vessels and digestive […]

The University of Arizona has licensed a drug that aims to shorten the lives of cancer cells to startup Reglagene. The technology, invented at the College of Pharmacy and the BIO5 Institute by Laurence Hurley and Vijay Gokhale, has been shown to be effective in shortening the lives of target cells, essentially inducing cancer cells to grow old […]

Cancer of the pancreas is a deadly disease, with a median survival time of less than six months. Only one in 20 people with pancreatic cancer survives five years past the diagnosis. The reason is the cancer’s insidiousness; tumor cells hide deep inside the body, betraying no symptoms until late […]

People who do hatha yoga report improved balance, but only now has yoga’s impact on falls received rigorous study. Now, University of Wisconsin–Madison professor of family medicine Irene Hamrick reports that the number of falls in older adults dropped 48 percent in the six months after yoga classes began, compared […]

An initial test to determine if a scalpel-free form of brain surgery can reduce tremor caused by Parkinson’s disease has produced encouraging results. Further research is warranted, the researchers conclude in a paper published Monday by the scientific journal JAMA Neurology. The pilot study, led by Dr. Jeff Elias of […]

Understanding the factors that control aging has been one of humanity’s endless pursuits, from the mystical fountain of youth to practical healthful regimens to prolong life expectancy. A team of scientists at the University of California San Diego has now helped decipher the dynamics that control how our cells age, […]

Cancer cells can be targeted and destroyed with the metal from the asteroid that caused the extinction of the dinosaurs, according to new research by an international collaboration between the University of Warwick and Sun Yat-Sen University in China. Researchers from the Professor Sadler and Professor O’Connor groups in Warwick’s […]

Colon cancer, Crohn’s, and other diseases of the gut could be better treated – or even prevented – thanks to a new link between inflammation and a common cellular process, established by the University of Warwick. Led by Dr Ioannis Nezis at Warwick’s School of Life Sciences, new research demonstrates […]

Researchers at the University of Minnesota have created a new lab-grown blood vessel replacement that is composed completely of biological materials, but surprisingly doesn’t contain any living cells at implantation. The vessel, that could be used as an “off the shelf” graft for kidney dialysis patients, performed well in a […]

Here’s an open invitation to steal. It goes out to cancer fighters and tempts them with a new program that predicts cancer drug effectiveness via machine learning and raw genetic data. The researchers who built the program at the Georgia Institute of Technology would like cancer fighters to take it for free, […]

A new study published in the journal Neuron sheds light on the normal function of LRRK2, the most common genetic cause for late-onset Parkinson’s disease.
