NASA’s Mars Perseverance rover provides front-row seat to landing, first audio recording of Red Planet

New video from NASA’s Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds […]

Astronomers confirm solar system’s most distant known object

With the help of the international Gemini Observatory, a Program of NSF’s NOIRLab, and other ground-based telescopes, astronomers have confirmed that a faint object discovered in 2018 and nicknamed “Farfarout” is indeed the most distant object yet found in our Solar System. The object has just received its designation from the International Astronomical Union.Farfarout was […]

Scientists manipulate magnets at the atomic scale

Fast and energy-efficient future data processing technologies are on the horizon after an international team of scientists successfully manipulated magnets at the atomic level. Physicist Dr Rostislav Mikhaylovskiy from Lancaster University said: “With stalling efficiency trends of current technology, new scientific approaches are especially valuable. Our discovery of the atomically-driven ultrafast control of magnetism opens […]

Vibrating 2D materials

Current electronic components in computers, mobile phones and many other devices are based on microstructured silicon carriers. However, this technology has almost reached its physical limits and the smallest possible structure sizes. Two-dimensional (2D) materials are therefore being intensively researched. One can imagine these materials as extremely thin films consisting of only one layer of […]

UK scientists build core components of global neutrino experiment

London: Engineers and technicians in the UK have started production of key piece of equipment for a major international science experiment.The UK government has invested $89 million (£65 million) in the international Deep Underground Neutrino Experiment, a particle physics experiment being built by the U.S. Department of Energy’s Fermilab at locations in both Illinois and […]

When galaxies collide

It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that […]

Mass human sacrifice?

Archaeologists have unearthed a trove of skulls in Mexico that may have once belonged to human sacrifice victims. The skulls, which date between A.D. 600 and 850, may also shatter existing notions about the ancient culture of the area.The find, described in the January issue of the journal Latin American Antiquity, was located in an […]

Personalized brain stimulation alleviates severe depression symptoms

Targeted neuromodulation tailored to individual patients’ distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson’s disease. Now, scientists at UC San Francisco’s Dolby Family Center for Mood Disorders have demonstrated a novel personalized neuromodulation approach that — at least in one patient — was able to […]

Immune system mounts a lasting defense after recovery from COVID-19, researchers find

As the number of people who have fought off SARS-CoV-2 climbs ever higher, a critical question has grown in importance: How long will their immunity to the novel coronavirus last? A new Rockefeller study offers an encouraging answer, suggesting that those who recover from COVID-19 are protected against the virus for at least six months, […]

A ‘super-puff’ planet like no other

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found. This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM’s Institute for Research on Exoplanets (iREx) suggests that […]

ALMA captures distant colliding galaxy dying out as it loses the ability to form stars

Galaxies begin to “die” when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have seen a galaxy ejecting nearly half of its star-forming gas. […]

Discovery boosts theory that life on Earth arose from RNA-DNA mix

In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial DNA. The finding is the latest in a series of discoveries, over […]

The upside of volatile space weather

Although violent and unpredictable, stellar flares emitted by a planet’s host star do not necessarily prevent life from forming, according to a new Northwestern University study. Emitted by stars, stellar flares are sudden flashes of magnetic imagery. On Earth, the sun’s flares sometimes damage satellites and disrupt radio communications. Elsewhere in the universe, robust stellar […]
