You check into a hotel and toss and turn all night, but your sleep improves the following night. Scientists at Nagoya University wanted to understand why this happens. Working with mice, they have identified a group of neurons ...

In efforts to better understand how soybean plants capture and use light, researchers at the University of Illinois Urbana-Champaign investigated how leaf size and shape affect light distribution within the crop canopy. Using ...

As humans age beyond early adulthood, their physical and mental functions tend to slowly worsen over time. One of the most common sources of severe mental decline in older adults are neurodegenerative diseases, conditions ...

NASA's Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency's Jet Propulsion Laboratory in Southern California, ...

Brazilian researchers have developed a synthetic compound that has the potential to treat malaria and block its transmission. The new molecule acts during three phases of the disease cycle, eliminating the asexual form of ...

Most near-Earth asteroids are thought to drift in from the main asteroid belt. But a small subset may have a much closer origin: the moon. One intriguing example is 469219 Kamoʻoalewa (2016 HO3), an Earth quasi-satellite ...

Dalhousie researchers have revealed how Arctic aquifers—permeable layers of the ground that store and transmit water to rivers, lakes and terrestrial ecosystems—behave today and how these vital resources will change with ...

An analysis of an unusual enzyme could result in a new generation of antimicrobial medicines to counter antibiotic resistance. Key details in the enzyme-driven biosynthesis of a natural molecule with potent antibiotic activity ...

Before tissue-engineered blood vessels reach the clinic, they must withstand the mechanical stresses of the vascular system—an assessment that is essential, but often expensive. One University of Pittsburgh research team ...

When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that ...

For people who are at high risk of developing breast cancer, frequent screenings with ultrasound can help detect tumors early. MIT researchers have now developed a miniaturized ultrasound system that could make it easier ...

Earth's ocean absorbs carbon dioxide from the atmosphere, helping to temper the impact of climate change but increasing ocean acidity. However, calcium carbonate minerals found in the seabed act as a natural antacid: Higher ...
