May the force (shoes) be with you

Researchers will use the ForceShoe to measure exercise loads and ground reaction forces, aiming to understand how joint forces differ between Earth-based exercises and those in microgravity. The goal is to recommend optimal exercise regimens for safe bone and muscle strength maintenance during spaceflight.

Barriers to HIV testing in older children

A new study from Zimbabwe found that providers are hesitant to test children for HIV due to concerns about guardianship and privacy. The research highlights the need for improved guidelines, training, and organizational adjustments to increase HIV testing and counseling among this vulnerable population.

Moving 'natural capital' from metaphor to reality

Economists at Yale School of Environment develop framework to value natural resources as long-term wealth stores, rather than commodities. The new approach combines economic and biophysical measurements to quantify feedbacks between nature and human behavior, providing a basis for accurate valuation.

A habitable environment on Martian volcano?

A Martian volcano, Arsia Mons, may have supported one of the most recent habitable environments on the Red Planet. Researchers found evidence of englacial lakes and volcanic lava flows that could have created a liquid water environment suitable for microbial life. The discovery is significant as it suggests that such environments may h...

Where have all the craters gone?

Researchers predict that only a few craters from asteroid impacts could persist on Earth due to tectonic processes and weathering. However, layers of molten rock blasted out during the impact process may serve as better records of impacts, providing insights into Earth's bombardment history.

Study identifies risk of chemotherapy related hospitalization for eary-stage breast cancer patients

Researchers used large population-based data to compare six common chemotherapy regimens, identifying those with the highest risk of hospitalization. The study found that TAC and AC+T were associated with high hospitalization rates in younger patients, while all regimens except ddAC+P had higher risks for older patients.

People attribute free will to mind, not soul

A new study suggests that people's perception of free will is based on the agent's ability to make intentional and independent choices, regardless of their spiritual beliefs. The study found that participants generally attributed free will to humans with mental capacity, but not to those without.

Ultraviolet cleaning reduces hospital superbugs by 20 percent: Study

Researchers found that ultraviolet environmental disinfection (UVD) significantly reduced healthcare-associated infections caused by multidrug-resistant organisms and Clostridium difficile. The study analyzed 52 months of hospital-acquired MDROs plus C. difficile before and during UVD use, resulting in a 20 percent decrease in superbugs.

Intertwined evolution of human brain and brawn

A recent study suggests that the evolution of human brain and brawn are intertwined. Human muscle accumulated more metabolic change than chimpanzees, while the human brain metabolome evolved four times faster. These findings may hold clues to common human metabolic diseases.
