Since the early 1930s, electron microscopy has provided unprecedented access to the alien world of the extraordinarily small, revealing intricate details that are otherwise impossible to discern with conventional light microscopy. But to achieve high resolution over a large specimen area, the energy of the electron beams needs to be cranked up, which is costly and detrimental to the specimen under observation.
Among former NFL players, Black, Hawaiian, and athletes from other racial backgrounds report worse physical, mental health outcomes than white players. The widest health gaps emerged between Black and white former NFL players. Black former players reported worse health outcomes in all five health categories, compared with their white peers. Presence of health disparities among former NLF players reflects the deep and pervasive nature of systemic inequities that persist even among elite athletes, study suggests.
The mechanisms that make organisms locally fit and those responsible for change are distinct and occur sequentially in evolution.
Discovering antiviral and anticancer drugs will soon be faster and cheaper thanks to new research.
A new publication on the impacts of deep-seabed mining by 13 prominent deep-sea biologists seeks to dispel scientific misconceptions that have led to miscalculations of the likely effects of commercial operations to extract minerals from the seabed.
Researchers found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies. They also discovered that higher levels of liver enzymes -- proteins released when the liver is damaged -- were associated with poorer outcomes for these patients, including ICU admission, mechanical ventilation, and death.
A new study found that 77% of low- to moderate-income American households fall below the asset poverty threshold, meaning that if their income were cut off they would not have the financial assets to maintain at least poverty-level status for three months.
Scientists use temperature data to tune -- and fix -- defects in 3D-printed metallic parts.
A new study using satellite mapping technology reveals there are nearly 20% more emperor penguin colonies in Antarctica than was previously thought. The results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird.
New research reveals how small molecule protease inhibitors show potency against human coronaviruses.
