Supermassive black holes reside in some of the biggest galaxies in the universe. They tend to be billions of times more massive that our Sun, and not even light itself can escape a black hole once it gets too close.

But it’s not all darkness. Supermassive black holes power some of the most luminous celestial objects in the universe – active galactic nuclei, which shine across the spectrum of light, including radio waves.

The active galactic nucleus in nearby galaxy Messier 87 is a prodigious emitter of radio waves, 27 orders of magnitude more powerful than the most powerful radio transmitters on Earth.

Google has revealed “Gemini”, which it says is its largest science and engineering project ever.

It is also the company’s latest attempt to catch up with rival OpenAI to develop artificial intelligence, and try and build a better system than its ChatGPT.

As such, Gemini will come to Google’s Bard, the chatbot that it released in the wake of ChatGPT in an attempt to catch up. But it will also roll out to Google’s Pixels phones and elsewhere.

Nearly four years into the pandemic, hundreds of Americans are still dying every day from Covid, according to the Centers for Disease Control and Prevention ( CDC).

The virus is responsible for around 1,000 deaths and 15,000 hospitalisations each week, CDC Director Mandy Cohen said during a media briefing on 2 December.

Death rates briefly dipped below 500 per week in July, the lowest rates since the pandemic began, before steadily increasing to as high as 1,400 in September.

This surprising result is important for understanding unconventional superconductors and other materials where electrons band together to act collectively.

Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat.

Long-term data from a study implemented by the # NIH-funded International Maternal Pediatric Adolescent AIDS Clinical Trials Network showed very early antiretroviral therapy (ART) for infants who acquired HIV in utero enabled some infants to sustain viral suppression for more than two years.

Very early ART for in-utero HIV-1 can achieve sustained virological suppression in association with biomarkers indicating restricted HIV-1 reservoirs by age 2 years, which might enable potential ART-free remission.

However, when major genome rearrangements occur — like the ones that the team was seeing in the skate’s DNA — boundaries can be lost, and the relative positions of genes on chromosomes can change. As a result, “some enhancers can provide instructions to the wrong gene,” explained Dario Lupiáñez, an evolutionary biologist at the Max Delbrück Center in Berlin and one of the senior authors of the study.

It seemed possible that the changes in the 3D architecture of the skate genome might have disrupted the ancient blocks of genes the skates inherited from their sharklike ancestors, affecting the genes’ function. “We were trying to look at whether some genome rearrangements in the little skate actually break these blocks,” said Ferdinand Marlétaz, a genomicist at University College London and co-first author of the study.
