The switch appears to sustain a fear … For The First Time, Physicists Measure Antimatter Falling in Gravity. As far as gravity is concerned, both matter and its charge-flipped 'mirror' twin, antimatter, deserve a big, warm hug. A recent experiment by international Antihydrogen Laser Physics Apparatus ( ALPHA) collaboration achieved the first direct measurement of free-falling ...

The ghost, at long last, is actually in the machine: For the first time, scientists have detected neutrinos created in a particle collider. Those abundant yet enigmatic subatomic particles are so removed from the rest of matter that they slide through it like specters, earning them the nickname "ghost particles".

9 hours ago · According to some studies, they occur in up to 2% of cases. If a hole or tear of the posterior capsule is encountered during cataract surgery, the clear gel in the vitreous – the back chamber of the eye – may be displaced into the front chamber of the eye. If that happens, the gel must be removed at the time of the cataract surgery.

We Just Got a Major Step Closer to Teleporting Images Using Only Light. Teleportation of quantum states promises to play a central role in securing the information superhighway of tomorrow. In spite of the headway that's been made, the process remains slow and kind of clunky. That could change, with scientists using a new process that could ... A stunning river of stars has been spotted flowing through the intergalactic space in a cluster of galaxies about 300 million light years away. Such bridges are known as stellar streams; and, at a length of 1.7 million light-years, the newly named Giant Coma Stream is the longest we've ever seen. And that's not all: the faint river is the first ...In 1906, zoologist Herbert Spencer Jennings reported a remarkable discovery. He found an example of intelligent behaviour in a freshwater organism made of just a single cell, known as Stentor roeseli. When stimulated under the microscope, this colourless, trumpet-like creature was able to make complex decisions, Jennings claimed.Göbekli Tepe, for instance, is a massive stone assembly in present-day Turkey constructed around 11,000 years ago.

The Quadrantids is due to peak at 12:53 UTC on 4 January 2024, with up to 110 to 120 meteors streaking through the atmosphere per hour. It's one of the most intense meteor showers to grace our skies per year, peaking sharply for up to just six hours before it subsides, leaving watchers who miss it to wait another 12 months for the next one ...A Chance Event 1 Million Years Ago Changed Human Brains Forever. Like treasured recipes passed down from generation to generation, there are just some regions of DNA that evolution doesn't dare tweak. Mammals far and wide share a variety of such encoded sequences, for example, which have remained untouched for millions of years.Material from a filament of plasma erupting from the Sun's surface broke away and appeared to form a crown-like vortex over the solar north pole. Further analysis will be required to determine whether or not this is what actually occurred. For now, scientists are saying that they've not quite seen anything like it – and the footage itself is ...Jun 1, 2022 · The author of a new research article in the International Journal of Astrobiology says that ETCs may not need starships to escape existential threats and travel to another star system. They could instead use free-floating planets, also known as rogue planets. The article is "Migrating extraterrestrial civilizations and interstellar colonization ... An international team of astronomers flipped it again in 2018 and found that a planetary nebula is indeed the most likely solar corpse. The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the ...

The impact of human activity on the Earth system could result in unpredictable chaos from which there is no return, physicists have calculated. This has led to the proposal of a new geological epoch: the Anthropocene, a period in which human activity has led to a significant and marked impact on the entire Earth system, comprised …The researchers set out to try and create and manipulate photonic crystal pseudogravity by distorting their photonic crystals experimentally. They created silicon photonic crystals, and introduced distortion by deforming the spacing between the ordered elements. This altered the way the crystal interacted with light, producing a curved beam ...

Fast radio bursts, or FRBs, are very strange, but very nifty. As the name suggests, they're bursts of radio emission that are very fast: each burst lasts just a few microseconds to seconds. They're really powerful, discharging in that short space of time as much energy as 500 million Suns. And they're a bit tricky to catch: most FRBs have only ...
