Ancient epigenetic changes silence cancer-linked genes

An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research suggests. Researchers uncovered that genes turned on in some cancers in humans also exist in zebrafish—but are ‘silenced’ within just hours of […]

Reaching and grasping: Learning fine motor coordination changes the brain

Reaching for and grasping objects brings about changes in the connections of a certain neuronal population in the red nucleus, a region of the midbrain, now reported by researchers at the University of Basel’s Biozentrum. They have also shown how fine motor tasks promote plastic reorganization of this brain region. The results of the study have been published in Nature […]

This Powerlifter Lost 180 Pounds With Small Changes to His Diet and Workout

At first, Fredrik Winge’s weight gain didn’t bother him too much—he’d seen the number going up for some time, but he’d also been lifting pretty regularly. “I thought I was just getting stronger, not fat,” he says. “So I just ate what I wanted and didn’t really care. It was mostly good food—I was just eating too much of it.” […]

Energy drinks may increase risk of heart function abnormalities and blood pressure changes

Drinking 32 ounces of an energy drink in a short timespan may increase blood pressure and the risk of electrical disturbances in the heart, which affect heart rhythm, according to a small study published in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association. The study enrolled 34 healthy volunteers between the […]

Experts call for halt to CRISPR editing that allows gene changes to pass on to children

Remember the global outrage four months ago at world-first claims a researcher had used the gene editing tool CRISPR to edit the genomes of twin girls? The molecular scissors known as CRISPR (CRISPR/cas9 in full) allow scientists to modify DNA with high precision and greater ease than previous technologies. Now researchers from the USA, Europe, China and New Zealand have […]

Sound changes the way rodents sense touch

The brain assigns sensory information from the eyes, ears and skin to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these cortices such that brain activation to one sense can influence brain activation to another. A new study by the laboratory of Associate Professor Shoji Komai at the […]
