Scrap for cash before coins Posted: 06 May 2021 02:41 PM PDT How did people living in the Bronze Age manage their finances before money became widespread? Researchers ave discovered that bronze scrap found in hoards in Europe circulated as a currency. These pieces of scrap -- which might include swords, axes, and jewellery broken into pieces -- were used as cash in the late Bronze Age, and in fact complied with a weight system used across Europe.

Evading the uncertainty principle in quantum physics Posted: 06 May 2021 11:21 AM PDT In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both be known fully precisely at the same time. Researchers now show that two vibrating drumheads, the size of a human hair, can be prepared in a quantum state which evades the uncertainty principle.

What can a dinosaur's inner ear tell us? Just listen Posted: 06 May 2021 11:21 AM PDT If paleontologists had a wish list, it would almost certainly include insights into two particular phenomena: how dinosaurs interacted with each other and how they began to fly.

Sharks use Earth's magnetic fields to guide them like a map Posted: 06 May 2021 11:20 AM PDT Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea.

Physicists describe new type of aurora Posted: 06 May 2021 09:58 AM PDT The famed northern and southern lights have been studied for millennia, but they still hold secrets. Physicists describe a new phenomenon they call 'diffuse auroral erasers,' in which patches of the background glow are blotted out, then suddenly intensify and reappear.

New study tracked large sharks during hurricanes Posted: 06 May 2021 07:55 AM PDT Biologists tracked large sharks in Miami and The Bahamas to understand how these migratory animals respond to major storms, like hurricanes.

First member of ill-fated 1845 Franklin expedition is identified by DNA analysis Posted: 06 May 2021 07:54 AM PDT The identity of the skeletal remains of a member of the 1845 Franklin expedition has been confirmed using DNA and genealogical analyses by a team of researchers.

Just a few atoms thick: New functional materials developed Posted: 06 May 2021 07:53 AM PDT Using the smallest 'construction set' in the world, a research team is designing new materials for computer chips, light-emitting diodes and solar cells.

New ant species named in recognition of gender diversity Posted: 05 May 2021 10:05 AM PDT A rare and unusual newly discovered ant from Ecuador has been named Strumigenys ayersthey, with the suffix '-they' chosen in contrast to traditional naming practices which, to date, fail to recognize gender diversity formally. The new species is distinguished by its predominantly smooth and shining cuticle surface and long trap-jaw mandibles.

A high-tech textile to stay comfortable outdoors Posted: 05 May 2021 08:14 AM PDT Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. Researchers now describe a high-tech alternative: a reversible textile they designed to trap warmth in the cold and reflect it during hot weather, all while generating small amounts of electricity.

An uncrackable combination of invisible ink and artificial intelligence Posted: 05 May 2021 08:13 AM PDT Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

Meet the freaky fanged frog from the Philippines Posted: 05 May 2021 08:13 AM PDT Biologists have described a new species of fanged frog discovered in the Philippines known as the Mindoro Fanged Frog.

A new window to see hidden side of magnetized universe Posted: 05 May 2021 08:13 AM PDT New observations and simulations show that jets of high-energy particles emitted from the central massive black hole in the brightest galaxy in galaxy clusters can be used to map the structure of invisible inter-cluster magnetic fields. These findings provide astronomers with a new tool for investigating previously unexplored aspects of clusters of galaxies.

3D bioprinting technique controls cell orientation Posted: 05 May 2021 08:13 AM PDT Scientists have developed a new approach for directing cell orientation within deposited hydrogel fibers via a method called multicompartmental bioprinting.

Bats know the speed of sound from birth, scientists discovery Posted: 05 May 2021 07:20 AM PDT Unlike humans, who map the world in units of distance, bats map the world in units of time. What this means is that the bat perceives an insect as being at a distance of nine milliseconds, and not one and a half meters, as was previously thought.

Legendary Sargasso Sea may be sea turtles' destination during mysterious 'lost years' Posted: 05 May 2021 06:44 AM PDT New research indicates that the legendary Sargasso Sea, which includes part of the Bermuda Triangle and has long featured in fiction as a place where ships go derelict, may actually be an important nursery habitat for young sea turtles. Researchers presented evidence of baby green sea turtles arriving at the Sargasso Sea after entering the ocean off the east coast of Florida.

Cryptic sense of orientation of bats localized: the sixth sense of mammals lies in the eye Posted: 05 May 2021 04:50 AM PDT Mammals see with their eyes, hear with their ears and smell with their nose. But which sense or organ allows them to orient themselves on their migrations, which sometimes go far beyond their local foraging areas and therefore require an extended ability to navigate? Scientific experiments now show that the cornea of the eyes is the location of such an important sense in migrating bats.

Microfossil found in Scottish Highlands could be 'missing link' in early animal evolution Posted: 03 May 2021 10:56 AM PDT A team of scientists has discovered the fossil of an organism with two distinct cell types that is likely the oldest of its kind ever recorded -- revealing multicellularity perhaps 400 million years before it first appeared in animals, they report. The discovery in the Scottish Highlands suggests that cell differentiation and segregation occurred at least one billion years ago and may have occurred in freshwater lakes rather than the ocean.
