Neal Agarwal published another gift to the internet with Size of Life. It shows the scale of living things, starting with DNA, to hemoglobin, and keeps going up. The scientific illustrations are hand-drawn (without AI) by Julius Csotonyi. Sound & FX by Aleix Ramon and cello music by Iratxe Ibaibarriaga calm the mind and encourage a slow observation of things, but also grow in complexity and weight with the scale. It kind of feels like a meditation exercise.

NDEs occasionally include encounters with deceased individuals whose death was unknown to the experiencer. If NDEs were driven by expectation, accurate perceptions of unknown (and surprising) facts should not occur. Though rare, such experiences are reported with enough regularity to warrant systematic investigation. A new research protocol aims to document such cases with greater rigor than has previously been possible.

You can't generate solar power at night unless your panels are in space. A startup that wants to beam orbital sunlight straight into existing solar farms has just emerged from stealth, claiming a world-first power-beaming demo, but with a lot of critical information left unreported. Overview Energy announced on Wednesday that, after three years developing its technology in stealth mode, it managed to get a Cessna Caravan plane to send power to a solar installation on the ground from an altitude of 3 miles

India was due to send its own spacecraft, crewed with its own astronauts, into orbit in 2022. But COVID-19 and a series of technical setbacks have consistently delayed the Gaganyaan mission's progress. ISRO the Indian Space Research Organization has now certified its LMV3 launch rocket for human travel and is aiming to complete three uncrewed launches of the Gaganyaan spacecraft in 2026. If things go to plan, three astronauts (or "Gaganyatris") selected from air force pilots Prasanth Balakrishnan, Ajit Krishnan, Angad Pratap and Shubhanshui Shukla, will be strapped in for the maiden voyage. The earliest that launch could take place is 2027.

Science is neither a collection of facts nor merely a process, but rather the combination of both. All at once, science is simultaneously the full suite of knowledge that we gain from observing, measuring, and performing experiments that test the Universe, as well as the process through which we perform those investigations and refine our conclusions based on an ever-increasing set of data.

The infamous San Andreas Fault Zone - a system with the main fault and many near-parallel faults - runs across much of California, dividing the Pacific tectonic plate from the North American one. The Pacific plate moves northwest about 2 inches per year, meaning Los Angeles is creeping toward San Francisco. The unsteady sliding between the two plates plays out in fits and starts. Sudden slips lead to earthquakes, which release the pent-up energy.

SAN FRANCISCO (KGO) -- When this monarch butterfly hits the sky it won't be traveling alone. In fact, an energetic team of researchers will be following along with a revolutionary technology that's already unlocking secrets that could help the entire species survive. "I've described this technology as a spaceship compared to the wheel, like using a using a spaceship compared to the invention of the wheel. It's teaching us so, so much more," says Ray Moranz, Ph.D., a pollinator conservation specialist with the Xerces Society.

It's easy to take for granted that with the flick of a lighter or the turn of a furnace knob, modern humans can conjure flames cooking food, lighting candles or warming homes. For much of our history, archaeologists think, early humans could only make use of fire when one started naturally, like when lightning struck a tree. They could gather burning materials, move them and sustain them. But they couldn't start a fire on their own.

Sarah Fortune, a marine ecologist at Dalhousie University in Nova Scotia, and her colleagues used drones and camera-equipped tags to study the killer whales over two weeks in August 2020. As they observed, they noticed something strangethe regular presence of Pacific white-sided dolphins (Lagenorhynchus obliquidens).

Itching arises with local inflammation from an insect bite, allergy, or other irritant. Itch sensations travel along small-diameter, slow neurons to the spinal cord and thence to the brain via the spinothalamic pathway [13]. Any patch of skin that itches also has mechanoreceptors that detect touch and vibration, whose signals make their way to the spinal cord via fast, large-diameter neurons that spinal neurons relay to the brain via a pathway called the dorsal columns [13].

R.G. carried out most of the experimental work and analysis. M.L. designed the study, wrote the first version of the manuscript and performed TEM analysis with F.M. and N.C. F.M. and R.G. created the algorithms to perform DIC and map matching across the various techniques. C.C., G.S. and R.G. performed the AFM work and analysis. O.R. created the nanocrystalline Al alloys.

Please be advised that there is significant solar flare and space weather activity, it read. The company, a maker of tractors and ball caps, isn't the first entity you'd turn to for advice about the sun. But the star's storms were messing with the GPS systems on John Deere's precision agricultural equipment, which uses geographic guidance to help farmers precisely plant, spray and harvest crops.

It's a fabulous weapon. It allows us to transform the world, understand ourselves, ask ourselves what we are All animals have a brain that allows them to survive, but we have done something much more powerful with it: we not only survived, but we have created a culture, a civilization And there's an enormous journey ahead: we might blow ourselves up before then through our own fault, but we have an unparalleled capacity for transformation and understanding

Researchers call this new type of material a 'corralled supercooled liquid'. Atoms in a liquid are normally like people in a busy crowd, constantly jostling and pushing past one another. However, scientists have now found a way to freeze some of these atoms in place, creating an immobile 'corral' that keeps the mobile liquid atoms trapped inside. Once the liquid is trapped inside a ring, its behaviour becomes different to any known form of matter.

Picture a scientist with a provocative hypothesis - something that defies conventional wisdom or verges on the outlandish. Supporting the pursuit of that big, bold claim is the goal of the Institute for Quantitative Social Science's new Extraordinary Claims, Extraordinary Evidence (ECEE) program. Designed for social scientists who want to explore highly controversial topics, the program helps tenure-track faculty generate the rigorous evidence necessary to assess their ideas.

A new reflective display could shatter those restrictions with resolutions beyond the limit of human perception. In a recent study in Nature, scientists describe a reflective retina e-paper that can display color video on screens smaller than two square millimeters across. The researchers used nanoparticles whose size and spacing affect how light is scattered, tuning them to create red, green and blue subpixels.

Supermassive black holes are the monsters of the universe, so it is perhaps only fitting that astronomers discovered one of these behemoths unleashing a bright x-ray flare that one of the researchers, astronomer Matteo Guainazzi, described as almost too big to imagine in a European Space Agency (ESA) press release. Within hours of erupting, the blast faded, and the black hole began to whip up winds more powerful than anything we can imagine on Earth

"[My train of thought] let its line down into the stream. It swayed, minute after minute, hither and thither among the reflections and the weeds letting the water lift it and sink it until-you know the little tug-the sudden conglomeration of an idea at the end of one's line."

The Northern Lights, also known as aurora borealis, may be visible in more than a dozen U.S. states Tuesday, December 9, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (NOAA). A full-halo coronal mass ejection (CME) is expected to reach Earth early to midday on Tuesday, potentially causing periods of "strong" G3 geomagnetic storms (on a scale of G1 to G5).

The problem In the dark days of winter, the whole house is darker, days are shorter, skies are greyer and our tropical houseplants receive far less light than they would in their natural habitat. Leaves fade and growth slows as plants struggle to photosynthesise. The hack Grow lights offer a clever fix, topping up what nature can't provide. But with prices ranging from 15 to 100, are they really worth it?
