FOR WRITERS Today’s writer topic comes from QSFer Scott: If you could visit one particular place – present, past or future – to research a story, where and when would it be? Writers: This is a writer chat – you are welcome to share your own book/link, as long as it fits the chat, but please do so as part of a discussion about the topic. Chat on FacebookChat on MeWe
In a mind-bending experiment, scientists transformed purified water into metal for a few fleeting seconds, thus allowing the liquid to conduct electricity. Unfiltered water can already conduct electricity — meaning negatively charged electrons can easily flow between its molecules — because unfiltered water contains salts, according to a statement about the new study. However, purified water contains only water molecules, whose outermost electrons remain bound to their designated atoms, and thus, they can’t flow freely through the water. Theoretically, if one applied enough pressure to pure water, the water molecules would squish together and their valence shells, the outermost ring … Read more
Ice is stiff and brittle — if you bend it, it will snap in two. Right? Not quite. Researchers just found that when grown in tiny strands, ice can defy its reputation for breakability, becoming so elastic it can even bend into a loop, according to a new study. These ice microfibers are so bendy that they are near the theoretical limit for ice elasticity. Perhaps even cooler, the scientists who grew the bendy ice think that their teensy ice strands could lead to both an avalanche of new ways to better understand ice in its natural state and more … Read more
Tardigrades, those adorable, chubby water bears, are notoriously hardy — they may even survive an apocalypse that wipes out humanity. But can these hardy water bears survive being shot from a gun? New research has found that yes, these hardy critters can make it out alive, but they also have a breaking point. The new study was inspired by uncertainty about the fate of tardigrades that were aboard Israel’s Beresheet probe when it crash-landed on the moon in 2019, according to Science magazine. Had the tardigrades, also called “water bears,” survived and contaminated Earth’s lifeless companion? After all, these teensy … Read more
When the precursor to today’s internet carried its first message in 1969, clunky but functional classical computers had already been around for decades. Now, physicists are designing the embryonic threads of a whole new internet for moving and manipulating a radically different type of information: the quantum bit, or “qubit.” And this time, they aren’t waiting for the corresponding computers to exist first. Two teams have now demonstrated an ensemble of technologies essential to building the backbone of such a network — devices known as quantum repeaters. The researchers managed, for the first time, to use light particles to bind … Read more
The moon is turning ever so slightly red, and it’s likely Earth’s fault. Our planet’s atmosphere may be causing the moon to rust, new research finds. Rust, also known as an iron oxide, is a reddish compound that forms when iron is exposed to water and oxygen. Rust is the result of a common chemical reaction for nails, gates, the Grand Canyon’s red rocks — and even Mars. The Red Planet is nicknamed after its reddish hue that comes from the rust it acquired long ago when iron on its surface combined with oxygen and water, according to a statement … Read more
Scientists sent patterns of electricity coursing across people’s brains, coaxing their brains to see letters that weren’t there. The experiment worked in both sighted people and blind participants who had lost their sight in adulthood, according to the study, published today (May 14) in the journal Cell. Although this technology remains in its early days, implanted devices could potentially be used in the future to stimulate the brain and somewhat restore people’s vision. Known as visual prosthetics, the implants were placed on the visual cortex and then stimulated in a pattern to “trace” out shapes that the participants could then … Read more
A bit of 4-billion-year-old rock blasted off the Martian surface about 15 million years ago and eventually landed in Antarctica, where explorers found it in 1984. In the decades since, organic compounds found in that meteorite have been sources of controversy: Did they come from Mars, or did the meteorites get contaminated on Earth? Now, a team of Japanese researchers has reexamined the meteorites, and say they found traces of ancient oceans, rich in useful carbon and nitrogen — key ingredients for life. The meteorite, known as Allan Hills 84001, after the location where it was first discovered, has long … Read more
Dark matter is a hypothetical component to our universe, used to explain many strange behaviors of stars and galaxies. Despite the almost overwhelming evidence that dark matter does indeed exist, we still don’t know what it’s made of. Detectors scattered around the world have been operating for decades, trying to catch the faint trace of a passing dark matter particle, but to no avail. A new paper offers an alternative approach: dig deep. We know that dark matter exists through a variety of astronomical observations. Stars are orbiting the centers of their galaxies too fast. Galaxies are whizzing around inside … Read more
Some people’s hearts stay strong well into their 60s, but their kidneys begin to fail. Others may have the kidneys of a 30-year-old but fall victim to constant infection. Now, scientists may be one step closer to understanding why the aging process varies so drastically between people. Even within a single person, aging unfolds at different rates in different tissues, sometimes striking the liver before the heart or kidney, for example. People fall into distinct categories depending on which of their biological systems ages fastest, and someday, doctors could use this information to recommend specific lifestyle changes and design personalized … Read more
