Making hydrogen from seawater can be tricky because the salt is corrosive and the process can create toxic chlorine gas – new electrodes can split ocean water to make the clean fuel more easily Making hydrogen from seawater can be tricky because the salt is corrosive and the process can create toxic chlorine gas – new…
A new study has shed light on the challenges of converting one type of specialized cell into another, a process critical for advances in regenerative medicine. Despite recent progress in the field, a key obstacle in maintaining the new identity of reprogrammed cells lies in their original DNA methylation patterns—crucial markers that define cell identity. A…
Ice may look safe for a game of pick-up hockey on the lake, but as a new study out of York University found, looks can be deceiving. Warming winters are not only affecting ice thickness and timing—when a lake freezes and thaws—but also quality, making it potentially unstable and unsafe. Ice may look safe for a…
The topological quantum computer still exists only in theory but, if possible, would be the most stable and powerful computing machine in the world. However, it requires a special type of qubit (quantum bit) that has yet to be realized and manipulated. The topological quantum computer still exists only in theory but, if possible, would be…
Bumblebees collect pollen by various methods. Some types of flowers, such as potato plants, need tougher treatment to make them release their pollen. In these cases, the bee uses a technique called “buzz pollination” where it bites the flower’s anthers and shakes them. Bumblebees collect pollen by various methods. Some types of flowers, such as potato…
Ecologists have long sought clarity on the dietary habits of different animal species. For scientists at Brown University and the National Park Service, it wasn’t obvious how herbivores in Yellowstone National Park, who subsist on grasses, wildflowers and trees, could compete for enough of those foods to survive the winter. Ecologists have long sought clarity on…
Astronomers study stars by looking at the different colors of light they emit—colors they capture and analyze using spectroscopy. Now a team led by Université de Montréal’s Étienne Artigau has developed a technique that uses a star’s spectrum to chart variations in its temperature to the nearest tenth of a degree Celsius, over a range…
A research team consisting of Professor Dong Sung Kim, Professor Anna Lee, and Dr. Jaeseung Youn from the Department of Mechanical Engineering at POSTECH has successfully recreated the structure of wrinkles in biological tissue in vitro, uncovering the mechanisms behind their formation. Their findings were published on August 19 in the journal Nature Communications. A research…
For more than 100 years, scientists have been using X-ray crystallography to determine the structure of crystalline materials such as metals, rocks, and ceramics.

A team of researchers from the University of Cape Town (South Africa) and the Max Planck Institute for Evolutionary Anthropology in Leipzig (Germany) have analyzed human remains from the Oakhurst rock shelter in southernmost Africa and reconstructed the genomes of thirteen individuals, who died between 1,300 and 10,000 years ago, including the oldest human genome…
