The future of data storage lies in DNA microcapsules      (via sciencedaily.com)     Original source 

Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.

Neutron star's X-rays reveal 'photon metamorphosis'      (via sciencedaily.com)     Original source 

A 'beautiful effect' predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar -- a neutron star featuring a powerful magnetic field, according to an astrophysicist.

Scientists recover an ancient woman's DNA from a 20,000-year-old pendant      (via sciencedaily.com)     Original source 

An international research team has for the first time successfully isolated ancient human DNA from a Paleolithic artefact: a pierced deer tooth discovered in Denisova Cave in southern Siberia. To preserve the integrity of the artefact, they developed a new, nondestructive method for isolating DNA from ancient bones and teeth. From the DNA retrieved they were able to reconstruct a precise genetic profile of the woman who used or wore the pendant, as well as of the deer from which the tooth was taken. Genetic dates obtained for the DNA from both the woman and the deer show that the pendant was made between 19,000 and 25,000 years ago. The tooth remains fully intact after analysis, providing testimony to a new era in ancient DNA research, in which it may become possible to directly identify the users of ornaments and tools produced in the deep past.

New tusk-analysis techniques reveal surging testosterone in male woolly mammoths      (via sciencedaily.com)     Original source 

Traces of sex hormones extracted from a woolly mammoth's tusk provide the first direct evidence that adult males experienced musth, a testosterone-driven episode of heightened aggression against rival males, according to a new study.

Astronomers find distant gas clouds with leftovers of the first stars      (via sciencedaily.com)     Original source 

Using ESO's Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions. These findings bring us one step closer to understanding the nature of the first stars that formed after the Big Bang.

'Gluing' soft materials without glue      (via sciencedaily.com)     Original source 

If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.

A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads      (via sciencedaily.com)     Original source 

It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.

What would the Earth look like to an alien civilization located light years away?      (via sciencedaily.com)     Original source 

What would the Earth look like to an alien civilization located light years away? A team of researchers has used crowd-sourced data to simulate radio leakage from mobile towers and predict what an alien civilization might detect from various nearby stars, including Barnard's star, six light years away from Earth.

Self-folding origami machines powered by chemical reaction      (via sciencedaily.com)     Original source 

Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.

A stormy, active sun may have kickstarted life on Earth      (via sciencedaily.com)     Original source 

The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.

Webb finds water vapor, but from a rocky planet or its star?      (via sciencedaily.com)     Original source 

Astronomers used NASA's James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about 800 degrees Fahrenheit (430 degrees Celsius). And yet, their observations show hints of water vapor.

Previously unknown intercellular electricity may power biology      (via sciencedaily.com)     Original source 

Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
