Scientists discovered evidence of magnetic fields in the universe’s cosmic web

Posted by in category: cosmology

The cosmic web is the term used to refer to the clusters, filaments, and voids that make up the large-scale structure of the Universe. In Λ cold dark matter (ΛCDM) cosmology, this web is formed from the anisotropic gravitational collapse of matter from primordial overdensities.

We’ve been able to map the Cosmic Web through observation over the past few decades, which opens up the possibility of finding answers to some of astronomy’s most pressing issues. An area of particular interest is how magnetic fields behave on a cosmic scale and their role in galactic and cosmic structure formation.

ICRAR scientists discover tantalizing evidence of magnetic fields in the universe’s most significant cosmic structures.

Meta Launches Subscription Service for Facebook and Instagram

Posted by in category: futurism

Facebook parent company Meta Platforms Inc. is launching a subscription service called Meta Verified that will include a handful of additional perks and features, including account verification badges for those who pay.

The new subscription will cost $11.99 per month — $14.99 if purchased through the iOS app — and is primarily targeted toward content creators. In addition to a verification badge, the subscription includes “proactive account protection, access to account support, and increased visibility and reach,” a Meta spokesperson said in an email.

Chief Executive Officer Mark Zuckerberg announced the new product via his Instagram Channel, a service that was unveiled in the past week. The option will be available on both Facebook and Instagram, but they’ll be separate subscriptions.

Achieving a better understanding of how the blood-brain barrier works

Posted by in categories: biotech/medical, engineering, neuroscience

Up to now, the use of models to research the barrier that separates the circulatory from the nervous system has proven to be either limited or extremely complicated. Researchers at ETH Zurich have developed a more realistic model that can also be used to better explore new treatments for brain tumors.

Mario Modena is a postdoc working in the Bio Engineering Laboratory at ETH Zurich. If he were to explain his research on the —the wall that protects our central nervous system from harmful substances in the —to an 11-year-old, he would say, “This wall is important, because it stops the bad guys from getting into the brain.” If the brain is damaged or sick, he says, holes can appear in the wall. Sometimes, such holes can actually be useful, for example, for supplying the brain with urgently needed medicine. “So what we are trying to understand is how to maintain this wall, break through it and repair it again.”

This wall is also important from a medical perspective, because many diseases of the central are linked to an injury to the blood-brain barrier. To discover how this barrier works, scientists often conduct experiments on live animals. In addition to such experiments being relatively expensive, may provide only part of the picture of what is going on in a . Moreover, there are some critics, who question the basic validity of animal testing. An alternative is to base experiments on that have been cultivated in the laboratory.
