Mutation discovery may improve treatment for rare brain tumor type
Scientists have identified a mutated gene that causes a type of tenacious, benign brain tumor that can have devastating lifelong effects.

Ultrasound directed to the human brain can boost sensory performance
Virginia Tech Carilion Research Institute scientists have demonstrated that ultrasound directed to a specific region of the brain can boost performance in sensory discrimination.

Nature study discovers chromosome therapy to correct a severe chromosome defect
Geneticists from Ohio, California and Japan joined forces in a quest to correct a faulty chromosome through cellular reprogramming.

Tweaking MRI to track creatine may spot heart problems earlier, Penn Medicine study suggests
A new MRI method to map creatine at higher resolutions in the heart may help clinicians and scientists find abnormalities and disorders earlier than traditional diagnostic methods, researchers at the Perelman School of Medicine at the University of Pennsylvania suggest in a new study published online today in Nature Medicine.

Study identifies population of stem-like cells where HIV persists in spite of treatment
Now investigators from Massachusetts General Hospital and the Ragon Institute of MGH, MIT and Harvard may have found where HIV persists in the bodyin spite of antiviral treatment -- in a small group of recently identified T cells with stem-cell-like properties.

Multi-institutional team finds targetable mutation in rare brain tumor
A team led by investigators from Massachusetts General Hospital, Brigham and Women's Hospital and the Broad Institute has found that a gene mutation associated with several types of cancer also may be responsible for a rare but debilitating brain tumor called papillary craniopharyngioma.

Scientists solve 40-year mystery of how sodium controls opioid brain signaling
Scientists have discovered how the element sodium influences the signaling of a major class of brain cell receptors, known as opioid receptors.

It's all coming back to me now: Researchers find caffeine enhances memory
Caffeine is the energy boost of choice for millions. Now, however, researchers have found another use for the stimulant: memory enhancer.

Research uncovers key difference between our bodies' fight against viruses and bacteria
Scientists at The University of Nottingham have discovered a key difference in the biological mechanisms by which the immune system responds to viral and bacterial pathogens.

High levels of molecular chlorine found in arctic atmosphere
Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.

UNC researchers find new route for better brain disorder treatments
Solving a 40-year-old mystery, scientists at the UNC School of Medicine and the Scripps Research Institute have discovered how salt acts as a key regulator for drugs used to treat a variety of brain diseases including chronic pain, Parkinson's disease, and depression.

Immune system development linked to leukemia
Researchers from the Wellcome Trust Sanger Institute and Institute of Cancer Research have discovered that a cellular mechanism that fights off infection is a driving force for a type of childhood leukemia.

Climate engineering -- what do the public think?
Members of the public have a negative view of climate engineering, the deliberate large-scale manipulation of the environment to counteract climate change, according to a new study.

Non-coding DNA implicated in type 2 diabetes
Variations in non-coding sections of the genome might be important contributors to type 2 diabetes risk, according to a new study.

Designer 'swiss-army-knife' molecule captures RNA in single cells in their natural tissue environment
A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells.
