Armed with gene technologies and CAR-Ts, scientists are attempting to eliminate viruses that escape immune detection and lurk in tissues for years.

In the realm of computing technology, there is nothing quite as powerful and complex as the human brain. With its 86 billion neurons and up to a quadrillion synapses, the brain has unparalleled capabilities for processing information. Unlike traditional computing devices with physically separated units, the brainâs efficiency lies in its ability to serve as both a processor and memory device. Recognizing the potential of harnessing the brainâs power, researchers have been striving to create more brain-like computing systems.
Efforts to mimic the brainâs activity in artificial systems have been ongoing, but progress has been limited. Even one of the most powerful supercomputers in the world, Rikenâs K Computer, struggled to simulate just a fraction of the brainâs activity. With its 82,944 processors and a petabyte of main memory, it took 40 minutes to simulate just one second of the activity of 1.73 billion neurons connected by 10.4 trillion synapses. This represented only one to two percent of the brainâs capacity.

Progression independent of relapse activity (PIRA) has been increasingly recognized in people with multiple sclerosis (MS; NEJM JW Neurol May 24 2022 and JAMA Neurol 2022; 79:682). To learn more about PIRA, investigators used data from the Italian MS Register on 16,130 patients with relapsing-remitting MS, including 1,383 with pediatric-onset MS (POMS; median age at onset, 16), 14,113 with adult-onset MS (AOMS; median age at onset, 29), and 634 with late-onset MS (LOMS; median age at onset, 52).
Compared with patients with POMS, patients with LOMS had the highest incidence of PIRA (hazard ratio
These authors provide data supporting the notion that MS pathophysiology is different between patients with PIRA and those with relapse-associated worsening. While relapse-associated worsening seems to increase gradually and reach a plateau, PIRA begins in the 20s and continues to increase. PIRA encompasses accumulating neurodegenerative processes, supporting the concept that a subset of patients experience progression even within the relapsing-remitting phase of the disease.
SpaceX rockets are tearing holes in the Earthâs atmosphere as they make their return to the surface, triggering what scientists are calling âSpaceX auroras,â a newly coined term that refers to red, spherical spots in the night sky that can easily be seen with the naked eye.
As Spaceweather.com reports, the name isnât entirely accurate as theyâre technically not auroras. Theyâre the result of SpaceX rockets burning their engines in the Earthâs ionosphere, a part of the upper atmosphere where solar radiation ionizes atoms and molecules to create a protective layer of electrons.
That means that as the rocketmaker ratchets up its launch schedule, that could be a problem, because the ionosphere serves an important technical function by ensuring the stability of shortwave radio communication and GPS signals.
SpaceX is making progress at Starbase, collaborating with the US Transportation Command and Air Force, potentially becoming a major source of revenue, while also facing potential competition from Relativity Space, and experiencing design errors but still managing to save samples.
Questions to inspire discussion.
Tesla has unveiled âOptimus Gen 2â, a new generation of its humanoid robot that should be able to take over repetitive tasks from humans.
Optimus, also known as Tesla Bot, has not been taken seriously by many outside of the more hardcore Tesla fans, and for good reason.
When it was first announced, it seemed to be a half-baked idea from CEO Elon Musk with a dancer disguised as a robot for visual aid. It also didnât help that the demo at Tesla AI Day last year was less than impressive.
People may be more than two times likelier to develop schizophrenia-related disorders if they owned cats during childhood than if they didnât:
Living with cats as a child has once again been linked to mental health disorders, because our furry friends apparently canât catch a break.
In a new meta-analysis published in the journal Schizophrenia Bulletin, Australian researchers identified 17 studies between 1980 and 2023 that seemed to associate cat ownership in childhood with schizophrenia-related disorders â a sample size narrowed down from a whopping 1,915 studies that dealt with cats during that 43-year time period.

Researchers have come one step closer to answering why, in some patients, a type of lymphoma changes from indolent to aggressive, and in particular, they are closer to identifying which patients are at high risk of this change happening.
Part of the answer lies in the protein expression in the tumor, explains Associate Professor Maja Ludvigsen from the Department of Clinical Medicine at Aarhus University. Maja is one of the authors of a new study on the subject, which has just been published in the journal Blood Advances.
Follicular lymphoma is an incurable lymphoma. But unlike many other cancers, it is not always aggressive from the start. This means that patients with the disease have to live with the uncertainty of whenâand howâthe cancer will develop. It also means frequent visits to the hospital to monitor any acute developments.
The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but thereâs still long way to go toward understanding this fundamental force.
