Blood markers predict Humboldt penguin nest type, reproductive success

Researchers looked at metabolic markers in the blood of 30 Humboldt penguins nesting in the Punta San Juan Marine Protected Area in Peru. The scientists discovered metabolic differences between penguins nesting in sheltered burrows and those in more exposed areas. Nesting success is critical to the Humboldt penguins' survival as a species.

Climate change could dramatically reduce future US snowstorms

A new study suggests American winters late this century could experience significant decreases in the frequency, intensity and size of snowstorms. Under an unabated greenhouse gas emissions scenario, the study projects 28% fewer snowstorms on average per year over central and eastern portions of North America by the century's last decade.

Bed bug burden in urban neighborhoods

In the first study to use systematically collected data from multifamily housing inspections to track bed bug infestation, investigators confirm what has long been suspected for bed bugs, but also for public health issues in general' -- infestations are strongly associated with socioeconomic factors, including neighborhood income, eviction rates and crowding.

More efficient biosolar cells modelled on nature

Potential sources of renewable energy include protein complexes that are responsible for photosynthesis. However, their efficiency in technical applications still leaves much to be desired. For example, they cannot convert green light into energy. A research team has successfully closed this so-called green gap by combining a photosynthesis protein complex with a light-collecting protein from...

These flexible feet help robots walk faster

Roboticists have developed flexible feet that can help robots walk up to 40 percent faster on uneven terrain such as pebbles and wood chips. The work has applications for search-and-rescue missions as well as space exploration.

Latest climate models show more intense droughts to come

An analysis of new climate model projections shows southwestern Australia and parts of southern Australia will see longer and more intense droughts due to a lack of rainfall caused by climate change. But Australia is not alone. Across the globe, several important agricultural and forested regions in the Amazon, Mediterranean and southern Africa can expect more frequent and intense rainfall...

A better model for neutrophil-related diseases

Neutrophils are critical immune cells for antimicrobial defense, but they can exacerbate a number of diseases, perhaps including COVID-19. The traditional approaches to study neutrophils in animal models are limited in specificity and effectiveness. Scientists have now identified the problem and have developed a new, optimized model for studying the role of neutrophils in the context of disease.
