New research from the University of Kentucky’s Sanders-Brown Center on Aging shows compelling evidence that the cognitive impairments observed in long COVID patients share striking similarities with those seen in Alzheimer’s disease and related dementias.
A next-generation COVID-19 mucosal vaccine is set to be a gamechanger not only when delivering the vaccine itself, but also for people who are needle-phobic.
ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner Solar System.
Up until the late 1960s, physiologists believed that the maximum depth a person could descend to was determined by the depth at which their total lung capacity (TLC) was compressed to the same volume as their residual volume (RV) which is the smallest lung volume a person can breathe to. The TLC was predicted to be…
A zinc-air microbattery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.
Note: These pages make extensive use of the latest XHTML and CSS Standards . They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in…

The ANPC transponder landing system at McMurdo station allows aircraft to land on the moving ice runway in poor weather or low visibility.
The AI Scientist: Towards Fully Automated Open-Ended Scientific Discovery
Device uses sound waves to gather blood pressure data from blood vessels, monitoring the response with ultrasound.
Nuclear power already has an energy density advantage over other sources of thermal electricity generation. But what if nuclear generation didn’t require a steam turbine? What if the radiation from a reactor was less a problem to be managed and more a source of energy? And what if an energy conversion technology could…
In a new study , a molecule identified and synthesized by UCLA Health researchers was shown to restore cognitive functions in mice with symptoms of Alzheimer’s disease by effectively jumpstarting the brain's memory circuitry.
CU Boulder Classics scholars identify previously unknown fragments of two lost tragedies by Greek tragedian Euripides.
By sheer accident, UBC researchers created a new super-black material that absorbs almost all light and trademarked it as Nxylon.
Butterflies and moths collect so much static electricity whilst in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimetres or centimetres.
What is the penguin’s skeleton truly made of? Do penguins actually have knees? Why do penguins walk that way. Find out here!
Warp drives are staples of science fiction, and in principle could propel spaceships faster than the speed of light. However, there are many problems with constructing them in practice, such as the requirement for an exotic type of matter with negative energy. Nevertheless, physicists have been exploring the…
The origin of the term is credited to Dr Gary L. Henderson, of the University of California at Davis. A designer drug is based on the structure of an existing drug – which may be naturally sourced from a plant (like cocaine or morphine ) or be synthetic (like amphetamine ) - but with a slightly different structure…
The key to curing male pattern baldness - a condition that affects up to 50 per cent of men worldwide - could lie in a sugar that naturally occurs in the human body, according to scientists at the University of Sheffield.
Launched in December 2013, ESA’s Gaia spacecraft is on a mission to map the locations and motions of more than a billion stars in the Milky Way with extreme precision.But it’s not easy being a satellite: space is a dangerous place. In recent months, hyper-velocity space dust and the strongest solar storm in 20 years…
With their quadruple personalities, those little brown birds at your feeder are a lot more interesting than they might appear.
A dual-mode ramjet was developed and tested in less than 11 monthsTesting demonstrates a threefold increase in airflow compared to previously flight-tested hypersonic technology
MIT Whitehead and Broad Institute researchers designed an epigenetic editor that can silence the prion protein gene, which could potentially be developed into a therapy against fatal prion diseases. The same approach could be used against other genetic diseases.
Scientists have discovered a molecular defect that promotes the pathologic immune response in lupus and demonstrated that reversing the defect may potentially reverse the disease.
Europe's new heavy-lift rocket, Ariane 6, made its inaugural flight from Europe's Spaceport in French Guiana at 16:00 local time on 9 July (20:00 BST, 21:00 CEST).

UChicago Pritzker Molecular Engineering Prof. Y. Shirley Meng’s Laboratory for Energy Storage and Conversion has created the world’s first anode-free sodium
Techniques developed to analyse the ripples in spacetime detected by one of the 21st century’s most sensitive pieces of scientific equipment have helped cast new light on the function of the oldest known analogue computer.
The mechanical computer uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components.
Some of the most perfectly preserved trilobite fossils ever found have revealed details of the extinct arthropod unknown until now.
