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 […]

Parental lifespan genes could hold clue to longer life

A large-scale international study led by the University of Exeter Medical School has discovered new genes linked to parents’ lifespan – which could one day be targeted to help prolong human life. How long we live is determined by a range of factors including our lifestyle and how well we treat factors […]

Safety Scissors

Like millions of Americans, Harvard Medical School postdoctoral fellow Tom Seegar struggled as he watched several family members decline from Alzheimer’s disease. “Seeing them start to lose what we most value—our minds and ability to think—was especially painful,” he said. Seegar’s desire to make a difference for people with Alzheimer’s helped motivate […]

Introducing the Genosenium

Scientists have wondered whether somatic, or non-inherited, mutations play a role in aging and brain degeneration, but until recently there was no good technology to test this idea. A study published online in Science, led by researchers from Boston Children’s Hospital and Harvard Medical School, used whole-genome sequencing of individual neurons […]

Stem cell reprogramming mystery clarified by new findings

Australian researchers have unearthed new evidence in a decade-long mystery concerning stem cell reprogramming, a process believed to hold immense potential for regenerative medicine. In a study, researchers from The University of Western Australia, the Harry Perkins Institute of Medical Research, and Monash University describe key drivers of the process […]

Shorter Course of Treatment May Provide Better Outcome for Men with Intermediate-Risk Prostate Cancer

Prostate cancer is the most common cancer among males in the United States. Approximately, 180,000 men are diagnosed each year, and approximately 95 percent of these men have localized disease that is potentially curable. Previously, studies have consistently demonstrated that conventionally fractionated high dose external beam radiation therapy (CRT), consisting […]

New weakness found in most common childhood malignant brain tumour

Current treatments for medulloblastoma include a combination of surgery, radiotherapy and chemotherapy which are not specific in how they target the tumour, and often lead to significant side effects, such as mental and physical disabilities. Treatment is further complicated by the fact that medulloblastoma is not a single disease but […]

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 […]

Parkinson's tremors modelled on a small scale – scientists observed a shaking fly

Tremors, involuntary movements and shaking, are probably the most noticeable symptoms of Parkinson‘s. They are significantly reducing people‘s quality of life and can push them into dependence on other people. Scientists up until now were not sure what causes tremors. Now researchers from the University of York managed to recreate […]

Researchers Identify New Protein Binding Characteristic That Could Better Treat Alzheimer's

As the rate and pervasiveness of Alzheimer's disease (AD) continue to spike across the United States, efforts to improve upon current treatments have grown simultaneously. Fortunately, there's been a recent technological breakthrough in understanding the mechanics behind AD. Scientists at Rice University invented a metallic probe that glows as it […]

Double-Edged Sword

Cancer therapies including radiation and chemotherapy seek to treat the disease by killing tumor cells. Now a team including researchers at Harvard Medical School and Beth Israel Deaconess Medical Center have shown that the dead and dying cancer cells generated by chemotherapy and targeted cancer therapy paradoxically trigger inflammation that […]
