Lunar South Pole Atlas—a new online reference for mission planners

The Lunar and Planetary Institute (LPI), managed by Universities Space Research Association (USRA), has compiled and made available an atlas of the Moon's south pole. Given NASA's recent direction to implement Space Policy Directive-1 landing astronauts at the south pole by 2024, the LPI has compiled a series of maps, images, and illustrations designed to provide context and reference for those interested in exploring this area.

Virtual reality game simulates experiences with race

Video games that use virtual reality to create immersive experiences have become increasingly popular for entertainment and for research. However, the representation of race in these simulations is often shallow—and fails to go beyond physical appearance attributes like skin color.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Ocean twilight zone scientists tackle the challenge of bringing light into darkness

Oceanographers studying creatures in the ocean twilight zone are facing an optical dilemma. They need to observe the fish in order to study them, but at ocean depths of 200 meters and beyond, there's very little natural light trickling down from the surface. This means that submersibles developed to image and track these animals need to be equipped with lights that can illuminate the animals—and do so without scaring them off.

New findings could lead to improved vaccinations against sexually transmitted infections

In a study published today in the Nature Communications, researchers from King's College London have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections (STIs).

Team develops EHR-based social needs screener to improve patient outcomes

Boston Medical Center (BMC) has implemented a social determinants of health screener for primary care patients in order to better identify and address patients' unmet social needs. Clinician researchers developed the electronic health record-based (EHR) model, THRIVE, which facilitates an automatic print out of referral information for resources based at the hospital and in the community when the patient asks for help with a need they have identified in the screener. The hospital's work, published in Medical Care, demonstrates an innovative systematic model that can help clinicians better address the social needs of patients to improve their overall health.

Children who use asthma tracking app have better disease control and fewer hospital visits

An app that allows parents and doctors to monitor a child's asthma has a big impact on managing the disease. When families monitored symptoms with eAsthma Tracker and adjusted care accordingly, children had better asthma control and made fewer visits to the emergency department. Using the app also meant that children missed fewer days of school and parents took fewer days off work, improving quality of life. Results of the study were published online in the journal Pediatrics.

Atlas is rockstar cross-stepper over tricky terrain

Robot enthusiasts were sending up cheers this month to the team advancing Atlas into an even more human-like walker through obstacles including a bunch of cinder blocks and a balance beam. They have turned Atlas into the very credible hulk, who wins the spotlight with its display of walking, which was recorded May 1.
