Practicing yoga nidra — a kind of mindfulness training — might improve sleep, cognition, learning, and memory, even in novices, according to a pilot study publishing in the open-access journal PLOS ONE on December 13 by Karuna Datta of the Armed Forces Medical College in India, and colleagues. After a two-week intervention with a cohort Read more about Yoga nidra might be a path to better sleep and improved memory[…]
Batteries that exploit quantum phenomena to gain, distribute and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power applications. For the first time, researchers, including those from the University of Tokyo, take advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the Read more about New way to charge batteries using indefinite causal order, comes with counterintuitive findings[…]

[…] Using realistic ecological modeling, scientists led by Western Sydney University’s Jürgen Knauer found that the globe’s vegetation could actually be taking on about 20% more of the CO2 humans have pumped into the atmosphere and will continue to do so through to the end of the century. “What we found is that a well-established Read more about Plants may be absorbing 20% more CO2 than we thought, new models find[…]
[…] Every clock has two fundamental properties: a certain precision and a certain time resolution. The time resolution indicates how small the time intervals are that can be measured—i.e., how quickly the clock ticks. Precision tells you how much inaccuracy you have to expect with every single tick. The research team was able to show Read more about Limits for quantum computers: Perfect clocks are impossible, research finds[…]
Dirty air killed more than half a million people in the EU in 2021, estimates show, and about half of the deaths could have been avoided by cutting pollution to the limits recommended by doctors. The researchers from the European Environment Agency attributed 253,000 early deaths to concentrations of fine particulates known as PM2.5 that Read more about Toxic air killed more than 500,000 people in EU in 2021, data shows[…]
Researchers at the Zurich-based ETH public university, along with a US-based startup called Inkbit, have done the impossible. They’ve printed a robot hand complete with bones, ligaments and tendons for the very first time, representing a major leap forward in 3D printing technology. It’s worth noting that the various parts of the hand were printed Read more about Researchers printed a robotic hand with bones, ligaments and tendons for the first time[…]
Synex Medical, a Toronto-based biotech research firm backed by Sam Altman (the CEO of OpenAI), has developed a tool that can measure your blood glucose levels without a finger prick. It uses a combination of low-field magnets and low-frequency radio waves to directly measure blood sugar levels non-invasively when a user inserts a finger into Read more about Researchers use magnetic fields for non-invasive blood glucose monitoring[…]
An international team of scientists has reconstructed a historic record of the atmospheric trace gas carbon monoxide by measuring air in polar ice and air collected at an Antarctic research station. The team, led by the French National Centre for Scientific Research (CNRS) and Australia’s national science agency, CSIRO, assembled the first complete record Read more about Three thousand years’ worth of carbon monoxide records show positive impact of global intervention in the 1980s[…]
[…] In recent years, some researchers have been puzzled upon finding that water in their experiments, which was held in a sponge-like material known as a hydrogel, was evaporating at a higher rate than could be explained by the amount of heat, or thermal energy, that the water was receiving. And the excess has been Read more about In a surprising finding, light can make water evaporate without heat[…]
