Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or ...
For 140 years, gold mines in Johannesburg, South Africa have been leaking wastewater contaminated with heavy metals. The acid mine drainage from Johannesburg's estimated 278 abandoned mines and 200 mine dumps includes uranium ...
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop ...
Lighting a gas grill, getting an ultrasound, using an ultrasonic toothbrush—these actions involve the use of materials that can translate an electric voltage into a change in shape and vice versa.
It is known that malfunctions of the proteins FLVCR1 and FLVCR2 lead to rare hereditary diseases in humans that cause motor, sensory and neurological disorders. However, the biochemical mechanisms behind this and the physiological ...
Humans arrived in Australia at least 65,000 years ago, according to archaeological evidence. These pioneers were part of an early wave of people traveling eastwards from Africa, through Eurasia, and ultimately into Australia ...
A team of physicists affiliated with several institutions in China has uncovered the reason behind the slipperiness of ice. In their study, published in the journal Nature, the group used atomic force microscopy to get a ...
The scorching surface of Venus, where temperatures can climb to 480°C (hot enough to melt lead), is an inhospitable place for humans and machines alike. One reason scientists have not yet been able to send a rover to the ...
A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro ...
Chemicals within microplastics that are found in our world's oceans and waterways, and in drinking water sources, remain of concern to scientists and public health officials. A new study that investigated the presence of ...
