What is the cosmological constant?
The cosmological constant is presumably an enigmatic form of matter or energy that acts in opposition to gravity and is considered by many physicists to be equivalent to dark energy. Nobody really knows what the cosmological constant is exactly, but it is required in cosmological equations in order to reconcile theory with our observations of the universe. /.../
70,000 never-before-seen viruses found in the human gut
Scientists have identified more than 70,000 previously unknown viruses that live in the human gut and infect the bacteria that live there — but how they impact our bodies is a mystery.
The gut microbiome, or the community of microbes that we carry around in our digestive system, plays an important role in food digestion and regulating the immune system, Live Science previously reported. But many studies have also linked imbalances in gut microbes to conditions including liver disease, obesity and allergies.
Yet shockingly little is known about the microbiome. Although the microbiome includes a variety of microorganisms — including bacteria and viruses — previous studies have focused mainly on gut bacteria because they are easier to detect.

Closing in on a complete human genome
Advances in sequencing technology mean that scientists are on the verge of finally finishing an end-to-end human genome map, 20 years after the first draft of the human genome was published. “This wasn’t just doing it for the sake of doing it,” says genomics researcher Karen Miga of the Telomere to Telomere (T2T) consortium, which is poised to complete the odyssey that began with the release of that first draft sequence. “It was because I think there’s some really cool biology there.”
Mars video reveals Perseverance rover’s daring touchdown
An image of Perseverance taken by a rocket-powered 'sky crane' as it lowered the rover onto Mars's dusty surface on 18 February.
Credits: NASA/JPL-CaltechHumanity has just been given a front-row seat to a Mars landing, thanks to a high-resolution, full--colour video that NASA released of its Perseverance rover descending into Jezero Crater on 18 February
The video shows the drama of the spacecraft’s final descent, from the 21.5-metre-wide parachute billowing overhead to slow it down, to the dusty orange landscape of Jezero gently rocking below as Perseverance drifted downwards, to the final moments when the rover’s six corrugated wheels touched down on a flat, rock-studded surface.
This video — the first of its kind — shows how Perseverance landed on Mars. As it whizzes toward the surface, it deploys a parachute, then the sky crane carefully lowers the rover to the landing site, kicking up dust and debris in the process. The footage was captured by multiple cameras mounted on the rover, the sky crane and a shell that protected the rover at the start of the descent. Credit: NASA/JPL-Caltech
