Hydrogen is a possible next generation energy solution, and it can be produced from sunlight and water using photocatalysts. A research group has now developed a strategy that greatly increases the amount of hydrogen produced using hematite photocatalysts. In addition to boosting the high efficiency of what is thought to be the world's highest performing photoanode, this strategy will be applied to artificial photosynthesis and solar water-splitting technologies via university-industry collaborations.

An international research team has conducted the first in-depth, wide-scale study of the genomic history of ancient civilizations in the central Andes mountains and coast before European contact. The findings reveal early genetic distinctions between groups in nearby regions, population mixing within and beyond the Andes, surprising genetic continuity amid cultural upheaval, and ancestral cosmopolitanism among some of the region's most well-known ancient civilizations.

People with body integrity dysphoria (BID) often feel as though one of their healthy limbs isn't meant to be a part of their bodies. They may act as though the limb is missing or even seek its amputation 'to feel complete.' Now, researchers have found that these feelings that a limb doesn't belong are mirrored in the brains of people with this condition.

Evidence continues to mount that the Neanderthals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study shows that Neanderthals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.

Hematopoietic stem cells from a healthy donor can help patients suffering from acute leukemia. However, the side effects of therapies are often severe. Researchers have now shown how human healthy and cancerous hematopoietic stem cells can be more selectively eliminated using immunotherapy instead of chemotherapy in mice. The aim is to test the new immunotherapy in humans as soon as possible.

As interest in the application of plasma medicine -- the use of low-temperature plasma (LTP) created by an electrical discharge to address medical problems -- continues to grow, so does the need for research advancements proving its capabilities and potential impacts on the health care industry. Across the world, many research groups are investigating plasma medicine for applications including cancer treatment and the accelerated healing of chronic wounds, among others.

The direction of ocean currents can determine the direction of gene flow in rafting species, but this depends on species traits that allow for rafting propensity. This is according to a study focusing on seahorse and pipefish species. And it could explain how high genetic diversity can contribute to extinction in small populations.
