FLIM, FRET and FLIRR don’t mean anything to most people, but to scientists studying the inner workings of cells, these high-resolution imaging techniques are essential tools for gaining insights to cellular behavior at the molecular level. Cells communicate with each other and multiply, and how they operate from within is […]

he evidence is clear: Cervical cancer is best treated with brachytherapy, a form of radiation therapy. Yet the use of this potentially life-saving treatment has been declining, and a new study from the University of Virginia School of Medicine may explain why. UVA researchers have determined that offering brachytherapy for […]

‘A Nobel Prize for the biological clock has long been overdue,’ says Dorothee Staiger. What is so remarkable is that the prize has been granted to basic research – that is, to studies on fundamental concepts in nature. Whereas the American colleagues have been analysing the biological clock in animals, […]

The efficacy of many FDA-approved cancer drug combinations is not due to synergistic interactions between drugs, but rather to a form of “bet hedging,” according to a new study published by Harvard Medical School researchers in Cell. Reanalyzing data from 15 clinical trials, the researchers show that independent action—in which drugs […]

  Scientists have identified differences in a group of genes they say might help explain why some people need a lot more sleep — and others less — than most.  The study, conducted using fruit fly populations bred to model natural variations in human sleep patterns, provides new clues to […]

Paralyzed rats with severed spinal cords are walking again, after Tel Aviv University and Technion–Israel Institute of Technology scientists restored their nervous function and sensation through tissue engineering and stem cells taken from the oral mucosa membrane of the mouth, Haaretz recently reported. The research was led by Prof. Daniel Offen of TAU's Sackler School of Medicine and […]

Scientists at the School of Dental Science in Trinity have made an important discovery involving bacteria and a pre-cancerous growth called oral leuoplakia which can precede oral cancer. The researchers examined the microbiome of oral leukoplakia in order to determine if certain bacteria were associated with oral leukoplakia and whether […]

New research by Yale Cancer Center (YCC) researchers shows a majority of pediatric cancer providers endorse the potential use of medical marijuana for children with advanced cancer, although providers who are legally eligible to certify its use are more cautious than those who aren’t. The findings also show clinicians would prefer to […]

A new large-scale international study expands the number of genetic markers now known to be associated with exceptional longevity. Researchers at the University of Connecticut, University of Exeter, University of Wisconsin, and University of Iowa undertook a genome-wide search for variants influencing how long participants’ parents lived. DNA samples carry […]

Human skin is a remarkable organ serving as a barrier protecting us from pathogens, toxic substances and others. Our skin needs to constantly renew throughout our lifetime as well as change its size to perfectly fit and cover the body. To fulfill such a complex and dynamic behavior every cell […]

Aging impairs the immune system’s response to the flu virus in multiple ways, weakening resistance in older adults, according to a Yale study. The research reveals why older people are at increased risk of illness and death from flu, the researchers said. “Influenza virus mortality is the highest in older […]

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered how high glucose levels — whether caused by diabetes or other factors — keep heart cells from maturing normally. Their findings help explain why babies born to women with diabetes are more likely […]
