New brain networks come ‘online’ during adolescence, allowing teenagers to develop more complex adult social skills, but potentially putting them at increased risk of mental illness, according to new research published in the Proceedings of the National Academy of Sciences (PNAS).
New antiviral materials made from sugar have been developed by researchers from the University of Manchester, the University of Geneva and the EPFL in Lausanne. They can destroy viruses on contact and may help in the fight against viral outbreaks. Although at an early stage of development, the broad-spectrum activity…
Remarkable relationship between psychedelics, the brain, well-being, and creativity
AUSTIN, Texas — For decades, researchers have looked for ways to eliminate cobalt from the high-energy batteries that power electronic devices, due to its
What is electricity? This question is impossible to answer because the word " Electricity " has several contradictory meanings. These different meanings are incompatible, and the contradictions confuse everyone. If you don't understand electricity, you're not alone. Even teachers, engineers, and scientists have a hard…
Researchers at EPFL have developed a new, high-precision method for 3D-printing small, soft objects. The process, which takes less than 30 seconds from start to finish, has potential applications in a wide range of fields, including 3D bioprinting.
Stanford researchers have determined that average human body temperature in the United States has decreased since the 1800s.
Tracking brainwave patterns and symptoms in patients with depression, researchers used artificial intelligence to predict best treatment options.
The new saliva collection method, which RUCDR developed in partnership with Spectrum Solutions and Accurate Diagnostic Labs, will allow for broader population screening than the current method of nose and throat swabs.
Iran’s new military satellite, NOUR 01, most interesting fact may not be that it resembles a college engineering experiment but rather that it may have a connection to a Mexican military payl…
Available at the arXiv this evening is something quite fascinating. Jim Cline has posted course notes from Feynman’s last course, given in 1987-88 on QCD. There are also some audio files of a…
In the last article we covered some of the historical pandemics that rocked the world - smallpox, typhoid, and the bubonic plague. We ended on a hopeful note - many of the pandemics that plagued the world in the past have faded, and that modern pandemics have been far less fatal than historical o
Several years ago, I developed a public lecture on the cosmic distance ladder in astronomy from a historical perspective (and emphasising the role of mathematics in building the ladder). I previous…
The coronavirus epidemic started one month earlier than is commonly reported and has yet to be brought under control, a new disease-transmission model created by University of Toronto researchers suggests. Using open access data that are updated daily, the model replicates epidemiological scenarios and allows…
How much plastic ends up in the ocean? Where does it come from?
Climeworks has signed groundbreaking agreements with Carbfix and ON Power to lay the foundation for a new plant that will significantly scale-up carbon...
Ingenious maneuvers by missions to go over the Sun, chase a comet and sail using the Sun.
MIT Professor Christopher Voigt and his team are working to transform cereal crops so they are able to fix their own nitrogen. The research has been funded by the Abdul Latif Jameel Water and Food Systems Lab (J-WAFS).
A quick look at the ballistics and stability of aerial fireworks.
Being able to feel empathy and to take in the other person's perspective – these are two abilities through which we understand what is going on in the other person's mind. Although both terms are in constant circulation, it is still unclear what exactly they describe and constitute. Scientists at the Max Planck…
