How the brain dials up the volume to hear someone in a crowd

How the brain dials up the volume to hear someone in a crowd

Our brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today’s discovery helps to solve a long-standing scientific question as to how the brain’s listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain. …read more

Researchers quantify Cas9-caused off-target mutagenesis in mice

Researchers quantify Cas9-caused off-target mutagenesis in mice

Scientists are finding new ways to improve the use of the CRISPR enzyme Cas9 and reduce the chances of off-target mutations in laboratory mice, according to new results. The findings will help scientists contextualize a common concern related to gene editing and identify new strategies to improve its precision. …read more

Limiting mealtimes may increase your motivation for exercise

Limiting mealtimes may increase your motivation for exercise

Limiting access to food in mice increases levels of the hormone, ghrelin, which may also increase motivation to exercise, according to a new study. The study suggests that a surge in levels of appetite-promoting hormone, ghrelin, after a period of fasting prompted mice to initiate voluntary exercise. …read more

When added to gene therapy, plant-based compound may enable faster, more effective treatments

When added to gene therapy, plant-based compound may enable faster, more effective treatments

Today’s standard process for administering gene therapy is expensive and time-consuming — a result of the many steps required to deliver the healthy genes into the patients’ blood stem cells to correct a genetic problem. Scientists believe they have found a way to sidestep some of the current difficulties, resulting in a more efficient gene delivery method that would save money and improve treatment outcomes. …read more

A simpler way to make some medicines

A simpler way to make some medicines

Organic chemists have figured out how to synthesize the most common molecule arrangement in medicine, a scientific discovery that could change the way a number of drugs — including one most commonly used to treat ovarian cancer — are produced. Their discovery, published today in the journal Chem, gives drug makers a crucial building block for creating medicines that, so far, are made with complex processes that result in a lot of waste. …read more
