Pinning down protons in water — a basic science success story
2025-09-11
New Haven, Conn. — The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is evident in everything from eyesight to energy storage to rocket fuel — and scientists have known about it for more than 200 years.
But no one has ever seen it happen. Or precisely measured it on a microscopic scale.
Now, the Mark Johnson lab at Yale has — for the first time — set benchmarks for how long it takes protons to move through six charged water molecules. The discovery, made possible with a ...
Scientists reveal how the brain uses objects to find direction
2025-09-11
We take our understanding of where we are for granted, until we lose it. When we get lost in nature or a new city, our eyes and brains kick into gear, seeking familiar objects that tell us where we are.
How our brains distinguish objects from background when finding direction, however, was largely a mystery. A new study provides valuable insight into this process, with possible implications for disorientation-causing conditions such as Alzheimer’s.
The scientists, based at The Neuro (Montreal Neurological Institute-Hospital) of McGill University and the University Medical Center Göttingen, ran an experiment with mice using ultrasound imaging to measure and record brain ...

2025-09-11
Images
A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum quasiparticles called excitons at room temperature.
The transistor-like switch developed by University of Michigan engineers could speed up information transfer or even enable circuits that run on excitons instead of electricity—paving the way for a new class of devices.
Because they have no electrical charge, excitons have the potential to move quantum information without the losses that come with moving electrically charged particles like electrons. ...
Scientist, advocate and entrepreneur Lucy Shapiro to receive Lasker-Koshland special achievement award
2025-09-11
In 1959, Lucy Shapiro, a freshman honors student at Brooklyn College majoring in arts and literature, had signed up for a course in inorganic chemistry on a lark. It didn’t interest her, and she stopped attending. But at the end of the term, having failed to officially drop the class, she was notified she had to take the final exam.
“It was a multiple-choice test, so I just circled all the B's,” recalled Shapiro, PhD, professor emerita of developmental biology and director of Stanford Medicine’s Beckman Center recalled. She received a D.
Three years later, the budding artist met physical ...

Zoology: Octopuses put their best arm forward for every task
2025-09-11
Octopuses can use any of their arms to perform tasks, but tend to use a particular arm, or arms, for specific tasks. This finding, presented in a paper in Scientific Reports, reveals more about the complex behaviour these animals display.
Octopus arms are complex structures consisting of four separate muscle groups — transverse, longitudinal, oblique, and circular — around a central nerve. These four muscle groups allow octopus arms to deform in a wide variety of ways to perform a range of actions used for various behaviours, from hunting and moving, to self-defence. However, little is known about how wild ...

Clocks created from random events can probe ‘quantumness’ of universe
2025-09-11
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal.
The researchers suggest that these formulae could help to understand how cells in our bodies measure time and to detect the effects of quantum mechanics in the wider world.
Studying these timekeeping processes could have far-reaching implications, helping us to understand proteins with rhythmic movements which malfunction in motor neurone disease or chemical receptors that cells use to detect harmful toxins.
Einstein famously said that “Time is whatever a clock measures” ...

The metals reveal: The Bronze Age was more connected than we previously thought
2025-09-11
In the Bronze Age, the so-called Nuraghe culture flourished in Sardinia. A culture that is known for tower-like stone constructions, nuraghers, and for the small bronze figures, bronzetti, which often depict warriors, gods and animals. These figures have fascinated scientists, but their exact metallic origins have been unknown.
To find out where the copper in these figures came from, the research team used a new scientific method called a multi-proxy approach (a combination of different chemical analyses). Here, they compared isotopes of copper, tin, lead and a rarer isotope called ...
Portable light-based brain monitor shows promise for dementia diagnosis
2025-09-11
Early and accurate diagnosis of dementia remains a major challenge. Standard approaches such as MRI and PET scans can provide valuable information about brain structure and function, but they are expensive, not always accessible, and often too expensive for repeated use. A team of researchers in the UK has now demonstrated that a compact, noninvasive technology—broadband near-infrared spectroscopy (bNIRS)—may offer a new way to detect brain changes linked to Alzheimer’s disease, even in the early stages.
In this pilot study reported in the Journal of Biomedical Optics, scientists used bNIRS to monitor both blood ...
