A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

Researchers demonstrated unprecedented rates of recovery for spinal cord injuries. Individuals with incomplete spinal cord injury safely received a combination of stimulation of a nerve in the neck with progressive, individualized rehabilitation. This approach, called closed-loop vagus nerve stimulation (CLV), produced meaningful improvements in arm and hand function in these individuals. Read more ›

Cancer cells respond to stress with greater diversity. Drugs that affect DNA replication, or radiation that causes direct DNA damage, lead to increasingly diverse offspring over multiple cell generations. This increases the tumor's genetic complexity and facilitates the development of resistance to therapy. Researchers have now investigated the emergence of cellular diversity in real time. Read more ›

Research teams funded by the National Institutes of Health (NIH) have created a versatile set of gene delivery systems that can reach different neural cell types in the human brain and spinal cord with exceptional accuracy. These delivery systems are a significant step toward future precise gene therapy to the brain that could safely control errant brain activity with high precision. In contrast, current therapies for brain disorders mostly treat... Read more ›

Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin's suspicion that this strategy might be a path to extinction. Read more ›

Trauma centers nationwide will begin to test a new approach for assessing traumatic brain injury (TBI) that is expected to lead to more accurate diagnoses and more appropriate treatment and follow-up for patients. The new framework expands the assessment beyond immediate clinical symptoms. Added criteria would include biomarkers, CT and MRI scans, and factors, such as other medical conditions and how the trauma occurred. Read more ›

Astronomers have filled a large gap in knowledge about Mars' water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like, suggesting that less of the planet's water may have been available to become rain and refill lakes and oceans.

New research could improve the efficiency of electrochemical carbon-dioxide capture and release by six times and cut costs by at least 20 percent. Researchers added nanoscale filtering membranes to a carbon-capture system, separating the ions that carry out the capture and release steps, and enabling both steps to proceed more efficiently.

Using the gene scissors CRISPR and stem cells, researchers have managed to identify a common denominator for different gene mutations that all cause the neurological disease ALS. The research shows that ALS-linked dysfunction occurs in the energy factories of nerve cells, the mitochondria, before the cells show other signs of disease, which was not previously known.

The Arctic is one of the coldest places on Earth, but in recent decades, the region has been rapidly warming, at a rate three to four times faster than the global average. However, current climate models have been unable to account for this increased pace. Now, researchers have reported that clouds may be to blame. Read more ›

Researchers have discovered how an ion channel in the brain's neurons has a kind of 'molecular memory', which contributes to the formation and preservation of lifelong memories. The researchers have identified a specific part of the ion channel at which new drugs for certain genetic diseases could be targeted. Read more ›
