Astronomers and astrologers may agree that the Age of Aquarius starts when the vernal equinox point moves out of constellation Pisces and into Aquarius. But when will that be? There’s no definitive answer. Source: https://earthsky.org/human-world/when-will-the-age-of-aquarius-begin…

Physicists observe competition between magnetic orders

They are as thin as a hair, only a hundred thousand times thinner—so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience when two Russian-British scientists were awarded the Nobel Prize in Physics in 2010 for the discovery of graphene, a building block of graphite. The special…

High-Frequency Traders Push Closer To Light Speed With Cutting-Edge Cables

High-frequency traders are using an experimental type of cable to speed up their systems by billionths of a second, the latest move in a technological arms race to execute stock trades as quickly as possible. From a report: The cable, called hollow-core fiber, is a next-generation version of the fiber-optic cable used to deliver broadband internet to homes and businesses. Made…

Bitcoin Hits New Record, This Time With Less Talk of a Bubble

Bitcoin is back. Again. From a report: Nearly three years after it went on a hair-bending rise and hit a peak of $19,783, the price of a single Bitcoin rose above that for the first time on Monday, according to the data and news provider CoinDesk. The cryptocurrency has soared since March, after sinking below $4,000 at the outset of the…

Duck! Meteor! Oh, Maybe Don’t Bother – This Time…

RockDoctor (Slashdot reader #15,477) is a professional geologist, and asks: Did anyone feel a sudden wind through their hair at about 17:19+00:00 on Monday, particularly in the mid Pacific? No? Good. Nobody else did. Nobody noticed the asteroid whizzing past just above the Earth’s atmosphere (for certain values of “above” including “not very far” and “373km above ground”). That’s the closest…

Raspberry Pi 4 Can Be Safely Overclocked To 2.15 GHz

szczys writes: When the Raspberry Pi 400 (a keyboard form-factor single board computer) was released last week, the company hinted at overclocking. Testing has now shown that the heat spreader used in that design does an excellent job. The chip was already clocked at 1.8 GHz, versus the stock 1.5 GHz in the original Raspberry Pi 4 Model B board. But…

Print These Electronic Circuits Directly Onto Skin

An anonymous reader quotes a report from IEEE Spectrum: New circuits can get printed directly on human skin to help monitor vital signs, a new study finds. In the new study, researchers developed a way to sinter nanoparticles of silver at room temperature. The key behind this advance is a so-called a sintering aid layer, consisting of a biodegradable polymer paste…
