Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficiently.
Is it true that two pieces of metal will permanently join together if they touch in a vacuum? In theory, yes.
The ESA/JAXA BepiColombo mission has captured its first views of its destination planet Mercury as it swooped past in a close gravity assist flyby last night.
Human anatomy still has a few surprises in store for us: researchers at the University of Basel have discovered a previously overlooked section of our jaw muscles and described this layer in detail for the first time.
How Bell Labs supported itself between moonshots
AUSTIN, Texas — Using generative artificial intelligence, a team of researchers at The University of Texas at Austin has converted sounds from audio
The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
In this post I'll describe how to sequence a human genome at home, something that's only recently become possible.
Somewhere below the Antarctic circle, I catch Tatiana, the waitress from the port side dining room, in a moment of leisure.
In an unusual trial, Stanford Medicine researchers found that a patient’s belief that they had received ketamine, even if they didn’t, could improve their depression.
In the past few months, I’ve twice injured the same ankle while playing with my kids. This, perhaps combined with covid, led me to several indisputable realizations: I am mortal.Despite my se…
is it safe to travel these days?
Once we emit about 1000 gigatons of carbon, much of the massive ice sheet will melt irreversibly. We’ve emitted 500 gigatons so far.
Researchers offer first proof that Ultraviolet C light with a 222 nm wavelength — which is safer to use around humans — effectively kills the SARS-CoV-2 virus.
Here is a cheap way to obtain a set of standard weights, for measuring weights up to about 100 gram, to an accuracy of about 0.5 gram : Use the coins of the currency of your country. Thus one can make use of the fact that these coins are fabricated in mass production, and because of that have not only a constant shape…
Myth of the Brown Recluse: Fact, Fear, and Loathing Rick Vetter Department of Entomology, University of California, Riverside, CA
In my first post on a possible solution to COVID-19 I hypothesised that there would be gene deletion mutants to be found in the SARS-CoV-2 viral strains out in the world and that we would find them if we looked.
Cellular (T cell) immunity against SARS-CoV-2 is likely to be present within most adults six months after primary infection, a new pre-print on bioRxiv suggests.

Airbus is working at full throttle to offer the German Air Force an operational Uncrewed Collaborative Combat Aircraft (UCCA) system by 2029.
Research on the ability of large language models to introspect on their own internal states.
Principles of how pulse oximetry works explained without using complicated physics.
The 2019 paper “Quantum supremacy using a programmable superconducting processor” asserted that Google’s Sycamore quantum computer, with 53 qubits and a depth of 20, performed a specific computat…
Promising results from an initial clinical trial show that sodium ascorbate – a pH-balanced formulation of vitamin C – is effective in treating sepsis.
By sheer accident, UBC researchers created a new super-black material that absorbs almost all light and trademarked it as Nxylon.
Somewhere at the bottom of the Forth and Clyde Canal, buried in the silt, there is a box of custom silicon that was right about almost everything. Back in 1988 a Scottish hi-fi company shipped a processor that checked the type and bounds of every memory access in hardware, garbage-collected its own heap in silicon, […]
