Extremely Dense Atom-sized Primordial Black Holes Could Weigh Millions of Tons, Experts RAtom-sized Primordial Black Holes Are Extremely Dense Objects That Could Weigh Millions of Tons, Experts Reveal

Posted by in categories: cosmology, particle physics

One of Albert Einstein’s theory of general relativity’s most fascinating predictions is the possibility of black holes, which are created after a massive star reaches the end of its life and collapses. Supermassive black holes as big as 100,000 or ten billion times the Sun are commonly found at the center of most galaxies.

Those are the biggest form of black holes, but it is also thought that primordial black holes (PBHs) also exist. Unlike the big ones, these tiny black holes emerged in the early cosmos through the gravitational collapse of extraordinarily dense areas.

Some Meta employees are getting paid to do ‘zero work’ as the company embarks on a ‘year of efficiency’: Financial Times

Posted by in category: futurism

The tech giant — which laid off 11,000 people in November and promised that 2023 is to be a “year of efficiency” — is gearing up for a new round of layoffs that might be wreaking havoc with some of the teams’ productivity, the Financial Times reported on Saturday, citing two employees familiar with the situation.

There’s been a lack of clarity about some budgets — which would typically get finalized by the end of the year — and future head count in recent weeks. Hence, projects and decisions that typically take days to sign off are taking up to a month, the Meta staffers told the FT.

That has caused some staff to do “zero work” because managers have not been able to plan their schedules.

Study Reveals How CBD Counters Epileptic Seizures

Posted by in category: neuroscience

Summary: Cannabidiol, or CBD, blocks the ability of lysophosphatidylinositol (LPI) to amplify neural signals in the hippocampus. LPI weakens the signals that counter seizures, further explaining the value of CBD to treat epilepsy.

A study reveals a previously unknown way in which cannabidiol (CBD), a substance found in cannabis, reduces seizures in many treatment-resistant forms of pediatric epilepsy.

EHT Peers Into The Heart of One of The Brightest Lights in The Universe

Posted by in categories: cosmology, physics

The global collaboration that delivered us not one but two pictures of supermassive black holes has now peered into one of the brightest lights in the Universe.

The Event Horizon Telescope (EHT), a telescope array comprising radio antennae around the world, studied a distant quasar named NRAO 530, whose light has traveled for 7.5 billion years to reach us.

The resulting data show us the quasar’s engine in incredible detail and will, astronomers say, help us understand the complex physics of these incredible objects, and how they generate such blazing light.

New Models Help Unveil the Mystery of Life’s Origins on Earth

Posted by in categories: biological, chemistry

New research reveals clues about the physical and chemical characteristics of Earth when life is thought to have emerged.

About four billion years ago, the first signs of life emerged on Earth in the form of microbes. Although scientists are still determining exactly when and how these microbes appeared, it’s clear that the emergence of life is intricately intertwined with the chemical and physical characteristics of early Earth.

“It is reasonable to suspect that life could have started differently—or not at all—if the early chemical characteristics of our planet were different,” says Dustin Trail, an associate professor of earth and environmental sciences at the University of Rochester.

Replacing Just 7 Minutes of Sedentary Behavior Every Day Could Boost Mid-Life Brain Power

Posted by in categories: health, neuroscience

Losing as little as 6–7 minutes per day to sedentary behavior or low-intensity activities has been linked to a decline in cognitive function, according to recent research.

The daily time spent in moderate and intense physical activity is linked to mid-life brain power, according to new research published in the Journal of Epidemiology & Community Health.

The results indicate that the optimal level for working memory and mental tasks, such as planning and organization, is at this intensity level. Replacing it with just 6–7 minutes of light-intensity activities or sedentary behavior per day is linked to decreased cognitive performance.
