Asus is only teasing its new Zenbook at this time, so we’ll have to wait until its formal introduction at the Always Incredible launch event on January 7 to get the full scoop. Given the battery life claims, however, it is likely that this new Copilot+ PC will be powered by a Snapdragon X chip.
You may not know that it was a 2017 Google research paper that kickstarted modern generative AI by introducing the Transformer, a groundbreaking model that reshaped language processing.
In the words of one of the researchers: “Black holes are not as destructive as we thought”
To make this record-breaking pass, the nearly 10-foot-long probe has made 22 orbits around the sun, allowing it to swoop ever deeper into the corona. And while doing so, the spacecraft has been continually picking up speed. When you repeatedly swing by such a massive and gravitationally powerful object — the sun is a sphere of hot gas 333,000 times as massive as our planet — you accrue lots of speed. Out in space, there’s nothing to stop this motion.
On this close flyby, the probe reached some 430,000 miles per hour (692,000 kilometers per hour).
“That’s like going from Philadelphia to Washington, D.C. in one second,” marveled Raouafi. “It’s fascinating. It’s the fastest human-made object ever.”
LLM models are already capable of diagnosing scientific outputs, but, until now, had no physical agency to actually perform’ experiments.
Tiny, ant-inspired magnetic microbots are capable of scaling obstacles, transporting heavy loads, and redefining medical technology.
The sun released over 50 X-class solar flares in 2024! Here we take a look at some of the best.
The standard medication levodopa does not always work against tremors in Parkinson’s disease, especially in stressful situations. Propranolol, however, does work during stress, providing insight into the role of the stress system in tremors. MRI scans reveal that propranolol directly inhibits activity in the brain circuit that controls tremors. Doctors may consider this medication when levodopa is ineffective.
People with Parkinson’s disease report that tremors worsen during stressful situations. “Tremors act as a sort of barometer for stress; you see this in all people with Parkinson’s,” says neurologist Rick Helmich from Radboud university medical center.
The commonly used drug levodopa usually helps with tremors, but it tends to be less effective during stress, when tremors are often at their worst. Helmich and his team wanted to investigate whether a medication targeting the stress system could help and how this effect of stress on tremors works in the brain. The work is published in the journal Annals of Neurology.
In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium. These components formed clusters of tiny liquid droplets–also known as condensates–with flexible and adaptable structures.
PolyP and magnesium are involved in many biological processes. Thus, the findings could lead to new methods for tuning cellular responses, which could have impactful applications in translational medicine.
The ensuing study, published in Nature Communications on October 26, 2024, reveals a delicate “Goldilocks” zone—a specific magnesium concentration range—where DNA wraps around polyP-magnesium ion condensates. Similar to a thin eggshell covering a liquid-like interior, this seemingly simple structure may help cells organize and protect their genetic material.
Researchers from Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) have identified a mechanism that may explain the neurological symptoms of long COVID.
The study shows that the SARS-CoV-2 spike protein remains in the brain’s protective layers, the meninges, and the skull’s bone marrow for up to four years after infection. This persistent presence of the spike protein could trigger chronic inflammation in affected individuals and increase the risk of neurodegenerative diseases.
The team, led by Prof. Ali Ertürk, Director at the Institute for Intelligent Biotechnologies at Helmholtz Munich, also found that mRNA COVID-19 vaccines significantly reduce the accumulation of the spike protein in the brain. However, the persistence of spike protein after infection in the skull and meninges offers a target for new therapeutic strategies.
