Scientists define the role for a rare, influential set of bone marrow cells

Researchers have defined the roles of various cells in the bone marrow that are thought to control the fate of the nearly half million blood cells that develop there each day. Scientists at NYU School of Medicine behind the new work say little had been known about the fraction of cells examined in the study, the “microenvironment” that makes up […]

Scientists find first evidence for necessary role of the human hippocampus in planning

A team of scientists reports finding the first evidence that the human hippocampus is necessary for future planning. Its findings, published in the journal Neuron, link its long-established role in memory with our ability to use our knowledge to map out the future effects of our actions. The results have implications for the way we think about afflictions that affect […]

Scientists identify genetic factors that may cause some people to become obese

Obesity is a major public-health problem in the United States and around the world, with an estimated 650 million people suffering from the condition. One of the biggest challenges of this ever-worsening condition is figuring out why people become obese in the first place, and why some people are more vulnerable to obesity than others. Now, scientists at The Rockefeller […]

Women scientists get less federal funding than men, new study finds

First-time women principal investigator scientists received considerably less funding from the National Institutes of Health (NIH) compared to first-time male principal investigators, even at top research institutions, reports a new study from Northwestern Medicine and the Kellogg School of Management. Previous research showed women receive lower startup funds from their universities to launch their research. This is the first study […]

Scientists identify new disrupted pathway in motor neurone disease

Researchers at the University of Sheffield have identified a new pathway that is disrupted in motor neurone disease (MND), a discovery which could pave the way for new treatments. The ground breaking findings were discovered by converting skin cells to brain cells called astrocytes, and comparing the energy metabolism of cells taken from MND patients versus healthy controls, using a […]

Scientists shed light on processes behind age-related decline in brain structures important for memory

Ageing can cause damage to support cells in the white matter, which in turn may lead to damage in the grey matter of the hippocampus, finds a new study by Cardiff University. The discovery gives researchers a new area to focus on in the search for treatments that can protect cognitive function. Claudia Metzler-Baddeley, from Cardiff University’s Brain Imaging Research […]

Scientists generate high-quality human vascular cells through genome editing technology

Scientists from the Institute of Biophysics of the Chinese Academy of Sciences (CAS), Peking University and the Institute of Zoology of CAS have generated the world’s first genetically enhanced human vascular cells by targeting a single longevity gene, FOXO3. The study was recently published in Cell Stem Cell. This six-year joint research effort represents the first time human vascular cell […]

Hong Kong scientists claim ‘broad-spectrum’ antiviral breakthrough

Hong Kong scientists claim they have made a potential breakthrough discovery in the fight against infectious diseases—a chemical that could slow the spread of deadly viral illnesses. A team from the University of Hong Kong described the newly discovered chemical as “highly potent in interrupting the life cycle of diverse viruses” in a study published this month in the journal […]

Scientists have learned how public transportation affects the spread of influenza and SARS

Although the connection of colds, with regular travel by public transport is widely acknowledged, the scientific evidence as they affect the spread of airborne infections, were never presented. A new study by the London underground, published in Environmental Health, confirmed the existence of this connection. This will contribute to the justification of measures to control the spread of infectious diseases. […]

Scientists discover ‘brain hot spot’ for drugs against fear

Anxiety disorders are a major medical problem affecting a large population. They can be treated with a range of psychiatric drugs, including a group of substances called benzodiazepines (BZDs). BZDs have been used to treat patients with anxiety for 50 years and it is well-understood what they do on the molecular and cellular level. However, doctors and neuroscientists had much […]
