Should you really be drinking eight glasses of water a day? What about reaching for a sports drink after exercise? Physiologist Tamara Hew-Butler is here to bust these hydration myths and more.

Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect. By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology.

A team at King’s College London has created a powerful new aluminum compound capable of doing the work of expensive rare metals. Its unique triangular structure gives it remarkable stability and reactivity, allowing it to drive chemical reactions in ways never seen before. The discovery could lead to greener and far more affordable industrial processes. It may even enable the creation of entirely new materials.

An infestation of caterpillars can make an oak tree postpone when it opens its leaves next year by three days, wrong-footing the insects when they attack again

With progress at COP climate meetings stalling, 57 countries took part in the first of a new series of conferences aiming to develop roadmaps away from fossil fuels, but big emitters like China and the US were absent

Silvia Park, author of the May read for the New Scientist Book Club, reveals how a book that was originally intended to be for children took a darker route following a death in the family

In this extract from Luminous, the May read for the New Scientist Book Club, we meet a mysterious robot discovered in a salvage yard in Seoul, in a future reunified Korea

Uranus’s outermost two rings are surprisingly dissimilar, which opens up a mystery about the tiny moons and moonlets that form them

I don't understand why public health figures like Jay Bhattacharya who controlled 58 billion dollars of funding uh didn't use that money to study it definitively and with running high quality trials.

The post Scientific Censor Dr. Jay Bhattacharya Doesn’t Realize He’s the Medical Establishment Now & It’s His Job to Generate Evidence for the American People first appeared on Science-Based Medicine.

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin on the theory that restores reality. Columnist Karmela Padavic-Callaghan explores how we could test Bohmian mechanics – and if it will ever become more widely accepted

You’re on the fourth human mission to Mars, and you’re told the Odyssey spacecraft designed to take you there will be the smoothest ride you’ll ever take. It features a newly christened electric propulsion engine which was in the late stages of testing during the first three missions. The mission starts and the spacecraft travels at a crawl, and you wonder if it’s broken. A week goes by and you’re now traveling at more than 400,000 kilometers (250,000 miles) per hour, and your mind is blown as to how fast you’re going, how quickly that happened, and that this mission might be more awesome than you thought.

Astronomers now believe there is at least one planet for every star in the Milky Way but new research has revealed a deeply unsettling twist in that picture. The most common planets in our Galaxy, it turns out, are almost entirely absent around the most common stars. Using data from NASA's TESS satellite, researchers found that the small, faint stars that make up the vast majority of the Milky Way seem to host rocky super Earths in abundance, but virtually no sub Neptunes, the planet type previously thought to be plentiful. The finding doesn't just refine existing theories of planet formation, it rewrites them.

An international team of astrophysicists has just released one of the largest cosmological datasets ever assembled. A mouthwatering 2.5 petabytes of simulated universe, freely available to researchers anywhere in the world. Built using a supercomputer and a suite of simulations called FLAMINGO, the data models how matter has evolved since the Big Bang, tracing everything from individual galaxies to the vast cosmic web that stretches across billions of light years.

When NASA's Artemis II crew swung around the Moon in April, the world watched in extraordinary detail and a breakthrough laser communications system was the reason why. Bolted to the outside of the Orion capsule, a compact optical terminal beamed 484 gigabytes of data back to Earth using invisible infrared light, outpacing traditional radio systems by a factor of tens. The result was some of the most vivid imagery ever captured in deep space, and a technology demonstration that will fundamentally change how humanity communicates beyond Earth.

Our Sun is a bit of an outlier in the general stellar population. We typically think of stars as being solitary wanderers throughout the galaxy. But roughly half of Sun-like stars are locked in with more than one companion star. If there are two, it’s known as a “binary” system, but in many cases there are even more stars all collectively tied together by gravity. Astronomers have long debated why this happens, and a new paper, available in pre-print on arXiv from Ryan Sponzilli, a graduate student at the University of Illinois, makes an argument for a mechanism known as disk fragmentation.

A cryptocurrency that aims to avoid the disastrous energy consumption of bitcoin is actually using 18 times more energy than its makers claim – but it promises improvements are on the way

An ambitious study has explored how the oral microbiome may affect our metabolic health, raising hopes that conditions like pre-diabetes could one day be screened for via a simple mouth swab

As I mentioned, a hen mallard came into Botany Pond yesterday and quickly took up with Armon, with him being protective and driving away other drakes.  Could this have been Vashti returning after she left the pond with her brood? The only way to tell is to compare bill photos, as hens have identifying dark marks on their bill. So I did the comparison, which you can see below.

Vashti: left side of bill (on nest)

New hen: left side of bill. same black markings on upper bill, black bill tip, and freckles on left side of bill:

Vashti: right side of bill:

New hen: right side of bill. This is the most dispositive to me: note the cloudy darkness on the right side with a small black clump on the bottom, along with the line of “freckles” extending ventrally.

This is good enough for me, and I am calling her “Vashti” again. Moreover, she’s back with Armon (they bonded very quickly after the new hen arrived at the pond yesterday), and they were showing breeding behaviors this morning (head bowing, etc.). My guess is that Vashti is going to essay a second brood.

The sad part is that Vashti almost certainly lost her brood after wandering away from Botany Pond, and came back to try again. The good bit is that she’s trying again, and I will be here to oversee the process again. And Armon is overseeing everything.

Duck tending is hard!

There are tens of thousands of Near-Earth Objects (NEOs) that represent some of the most easily accessible resources in the solar system. If we can get to them at least. Planning trajectories to rendezvous with these miniature worlds is notoriously difficult, and requires a massive amount of computational power to calculate. But a new paper from astrodynamicist Alessandro Beolchi of Khalifa University of Science and Technology and his co-authors offers a much less computationally intensive way to find these trajectories, and has the added bonus of finding the much less energy-intensive paths to boot.
