At UVA's Keck center, researchers peer deep into inner workings of cells

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 […]

Study: a gold – standard cancer treatment is in decline, and money may be why

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 […]

The biological clock of plants

‘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, […]

Combination Rethink

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 Make Paralyzed Rats Walk Again

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 […]

Researchers make important discovery in oral pre-cancer condition

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 […]

Pediatric cancer providers give medical marijuana a cautious thumbs-up

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 […]

Number of Genetic Markers Linked to Lifespan Triples

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 […]

Aging impairs innate immune response to flu

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 […]

Research reveals how diabetes in pregnancy affects baby's heart

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 […]

MRI scans predict patients’ ability to fight the spread of cancer

A simple, non-invasive procedure that can indicate how long patients with cancer that has spread to the brain might survive and whether they are likely to respond to immunotherapy has been developed by researchers in Liverpool. The technique, which can be done using standard hospital-based Magnetic Resonance Imaging (MRI) scans, […]

How food affects your mood? Scientists say it depends on how old you are

Humans are weird. We have emotions we cannot control or, sometimes, explain. For example, why are we so moody sometimes? Scientists from the Binghamton University have conducted a survey, which showed how various food items affect our mood. Interestingly, this effect changes as we age. Scientists conducted a survey online […]

Research reveals how cells rebuild after division

When cells divide, they need to rebuild their nucleus and organise their genome. New collaborative research from the University of Bristol demonstrates how cells achieve this through the unexpected deployment of filamentous actin (F-actin) to the nucleus. The research, published online in Nature Cell Biology, provides the first evidence that actin […]
