Scientists report the first “strong direct evidence” for a fundamental cosmic phenomenon in a region of space near the beginning of the universe.
Science: for who ever want to landing or touch the sun 🌞 ☀️. Yeah what was believed impossible can become true.
NASA’s Parker Solar Probe is set to pass the Sun this year in a milestone moment for space exploration.
The probe, launched on Aug 12, 2018, is due to fly past the sun at 195 km/s, or 435,000 mph on 24 December 2024, the BBC reported.
NASA describes it as a mission to “” touch the Sun” on its website, aiming to get our “first-ever sampling of a star’s atmosphere.”
Researchers have developed an ultra-robust time crystal, and a new method to keep it stable for over 40 minutes.
DUNE, a neutrino research project, seeks to unravel the matter-antimatter imbalance mystery by tracking neutrino transformations.
An AI algorithm outperformed other screening methods in identifying cervical precancer. The approach could be especially valuable in low-resource settings.
In the animal kingdom, there are many grand examples of species that make sense of their world by expertly deciphering even weak signals from their surroundings.
An eagle soaring above the ground spies a river fish down below, about to swallow a bug; a hungry black bear smells a morsel of food two miles away in a dense thicket; a duck-billed platypus, swimming in a freshwater creek, closes its eyes and detects the electric impulses of a tasty tadpole nearby.
Then there are the pit vipers.
A team of astronomers, led by Arizona State University Assistant Research Scientist Tim Carleton, has discovered a dwarf galaxy that appeared in James Webb Space Telescope imaging that wasn’t the primary observation target.
Galaxies are bound together by gravity and made up of stars and planets, with vast clouds of dust and gas as well as dark matter. Dwarf galaxies are the most abundant galaxies in the universe, and are by definition small with low luminosity. They have fewer than 100 million stars, while the Milky Way, for example, has nearly 200 billion stars.
Recent dwarf galaxy observations of the abundance of “ultra-diffuse galaxies” beyond the reach of previous large spectroscopic surveys suggest that our understanding of the dwarf galaxy population may be incomplete.
A team of molecular engineers have developed a type of plastic that can be shape-shifted using tempering. In their paper published in the journal Science the team, from the University of Chicago, with a colleagues from the US DEVCOM Army Research Laboratory, Aberdeen Proving Ground, the National Institutes of Standards and Technology and the NASA Glenn Research Center, describe how they made their plastic and how well it was able to shape shift when they applied various types of tempering.
Haley McAllister and Julia Kalow, with Northwestern University, have published a Perspective piece in the same issue of Science outlining the work.
Over the past several years, it has become evident that the use of plastics in products is harmful to not only the environment but also human health —bits of plastic have been found in the soil, the atmosphere, the oceans, and the human body.
An international team of linguistics experts has traced the origins of the most common modern sign languages using a computer model to compare them against one another. The research is published in the journal Science.
In this new effort, the research team noted that while studies have traced the linguistic history of written languages, little work has been done on the origin of sign languages. They state that there are more than 300 sign languages used by hearing-impaired people around the globe, and little is known about their origins or how they might have impacted one another.
Sign languages, like spoken and written languages, are unique to groups or cultures, with many corresponding to their written counterparts—there is a Spanish sign language, for example, and French, Spanish and Japanese.
