Lack of genetic variation is never good for species survival.
A newly developed nanomaterial that mimics the behavior of proteins could be an effective tool for treating Alzheimer’s and other neurodegenerative diseases. The nanomaterial alters the interaction between two key proteins in brain cells—with a potentially powerful therapeutic effect.
The innovative findings, recently published in the journal Advanced Materials, were made possible thanks to a collaboration between University of Wisconsin–Madison scientists and nanomaterial engineers at Northwestern University.
The work centers around altering the interaction between two proteins that are believed to be involved in setting the stage for diseases like Alzheimer’s, Parkinson’s and amyotrophic lateral sclerosis, or ALS.

Not many devices in the datacenter have been etched with the Intel 4 process, which is the chip maker’s spin on 7 nanometer extreme ultraviolet immersion lithography. But Intel’s Loihi 2 neuromorphic processor is one of them, and Sandia National Laboratories is firing up a supercomputer with 1,152 of them interlinked to create what Intel is calling the largest neuromorphic system every assembled.
With Nvidia’s top-end “Blackwell” GPU accelerators now pushing up to 1,200 watts in their peak configurations, and require liquid cooling, and other accelerators no doubt following as their sockets get inevitably bigger as Moore’s Law scaling for chip making slows, this is a good time to take a step back and see what can be done with a reasonably scaled neuromorphic system, which not only has circuits which act more like real neurons used in real brains and also burn orders of magnitude less power than the XPUs commonly used in the datacenter for all kinds of compute.
As the driest nonpolar desert in the world, the Atacama Desert in northern Chile is home to very few species of plants and animals. With rainfall often occurring only once a decade, the desert is so dry that NASA uses it as a stand-in for the Martian landscape. But what’s living beneath the parched surface? New research suggests it’s very small, abundant, and old, very old.
While the Atacama Desert’s aridity means that higher forms of life are scarce, it’s well-known that diverse bacteria dominate its soils. However, the researchers aimed to go deeper to see what species of microbes lived more than a meter (3.3 ft) beneath the surface.
Cyber attackers are experimenting with their latest ransomware on businesses in Africa, Asia, and South America before targeting richer countries that have more sophisticated security methods.
Hackers have adopted a “strategy” of infiltrating systems in the developing world before moving to higher-value targets such as in North America and Europe, according to a report published on Wednesday by cyber security firm Performanta.
“Adversaries are using developing countries as a platform where they can test their malicious programs before the more resourceful countries are targeted,” the company told Banking Risk and Regulation, a service from FT Specialist.
The Large Hadron Collider is testing entanglement in a whole new energy range, probing the meaning of quantum theory – and the possibility that an even stranger reality lies beneath.
