The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
A combined study of genetics and skeletal remains show that the switch from primarily hunting, gathering and foraging to farming about 12,000 years ago in Europe may have had negative health effects as indicated by shorter ...

(Phys.org) —Researchers at Eindhoven University of Technology in The Netherlands have found that treating pavement with titanium oxide causes a reduction in nitrogen oxide air pollution. In their paper published in the ...
(Phys.org)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
Scientists have found that a perpendicular magnetic field makes electrically neutral quasiparticles (excitons) in semiconductors behave like electrons in the Hall effect. This discovery will help researchers to study the ...
