Researchers enhance durability of pure water-fed anion exchange membrane electrolysis
2025-11-18
Anion exchange membrane (AEM) water electrolysis is widely recognized as a key technology for next-generation green hydrogen production. Currently, most AEM systems rely on alkaline supporting electrolytes such as potassium hydroxide, which can cause issues including bipolar plate corrosion, shunt current, and accelerated membrane degradation.
Achieving stable operation with pure water feed is the goal for AEM water electrolysis. However, obstacles remain such as the instability of the membrane-electrode three-phase interface, limited current density, and poor durability.

Loss of key visual channel triggers rhythmic retinal signals linked to night blindness
2025-11-18
Rhythmic electrical activity in the retina (known as pathological oscillations) has been observed in several eye diseases, including congenital stationary night blindness (CSNB) and retinitis pigmentosa (RP). These oscillations interfere with the normal transmission of visual information to the brain, often causing degraded or distorted perception. Although scientists have long known that such oscillations occur in retinal ganglion cells (RGCs), the neurons responsible for sending visual signals to the brain, the cellular mechanism that drives this rhythmic activity has remained elusive.
In a recent study published online in The Journal of General Physiology on October 16, ...
New study suggests chiral skyrmion flows can be used for logic devices
2025-11-18
In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they have been created and controlled at room temperature in many materials. Skyrmions, as nonvolatile information carriers, are key in electronic and spintronic devices. Their size can be just a few nanometers, enabling high storage densities. They require low current to move, are topologically stable, and offer nonvolatility and radiation hardness for extreme environments.
Over the past decade, most published reports in the field, both experimental and theoretical, have focused on the applications ...

Could a drought have no end? Fifteen years of severe and persistent drought in Chile have already passed, and the country ...
UC Irvine researchers link Antarctic ice loss to ‘storms’ at the ocean’s subsurface
2025-11-18
Irvine, Calif., Nov. 18, 2025 — Researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have identified stormlike circulation patterns beneath Antarctic ice shelves that are causing aggressive melting, with major implications for global sea level rise projections.
In a paper published recently in Nature Geoscience, the scientists say their study is the first to examine ocean-induced ice shelf melting events from a weather timescale of just days versus seasonal or annual timeframes. This enabled them to match “ocean storm” activity with intense ice melt at Thwaites Glacier ...
Deep brain stimulation successful for one in two patients with treatment-resistant severe depression and anxiety
2025-11-18
Deep brain stimulation – implants in the brain that act as a kind of ‘pacemaker’ – has led to clinical improvements in half of the participants with treatment-resistant severe depression in an ‘open label’ trial.
Significantly, the study, led by researchers in the UK and China, identified a telltale signature of brain activity that predicted how well individual patients responded to the treatment. This could be used in future to target the treatment at those patients most likely to benefit.
Major ...
Single-celled organisms found to have a more complex DNA epigenetic code than multicellular life
2025-11-18
The background: Multicellular organisms (animals, plants, human) all have the ability to methylate the cytosine © base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and processes such as aging.
The findings: In this new paper, the researchers discovered that in more ‘primitive’ unicellular organisms, both the adenine and the cytosine bases are methylated. This would suggest that in some ways, these unicellular organisms are more complex than their multicellular peers. The team also found that methylation of the adenine ...

Weather behind past heat waves could return far deadlier
2025-11-18
The weather patterns that produced some of Europe’s most extreme heat waves over the past three decades could prove far more lethal if they strike in today’s hotter climate, pushing weekly deaths toward levels seen during the COVID pandemic, according to a November 18 study in Nature Climate Change.
“We showed that if these same weather systems were to occur after we’ve trapped a lot more heat in the atmosphere with greenhouse gases, the intensity of the heat waves gets stronger and ...
Ultrasonic device dramatically speeds harvesting of water from the air
2025-11-18
Feeling thirsty? Why not tap into the air? Even in desert conditions, there exists some level of humidity that, with the right material, can be soaked up and squeezed out to produce clean drinking water. In recent years, scientists have developed a host of promising sponge-like materials for this “atmospheric water harvesting.”
But recovering the water from these materials usually requires heat — and time. Existing designs rely on heat from the sun to evaporate water from the materials and condense it into droplets. But this step can take hours or even days.
Now, MIT engineers ...
