De novo birth of functional microproteins in the human lineage

Posted by in categories: biotech/medical, evolution, genetics

Human microproteins encoded by small ORFs have been found to be functional. By comparing the corresponding sequences across vertebrate genomes, Vakirlis et al. show that a number of these originated “from scratch” from noncoding sequences, including two very recent cases unique to humans. These cases demonstrate the rapid evolution of genetic novelty.

Glass act: Scientists reveal secrets of frog transparency

Posted by in category: neuroscience

WASHINGTON (AP) — Now you see them, now you don’t.

Some frogs found in South and Central America have the rare ability to turn on and off their nearly transparent appearance, researchers report Thursday in the journal Science.

During the day, these nocturnal frogs sleep by hanging underneath tree leaves. Their delicate, greenish transparent forms don’t cast shadows, rendering them almost invisible to birds and other predators passing overhead or underneath.

Behold! This gorgeous galaxy image merges Hubble and Webb data in stunning detail

Posted by in category: cosmology

NGC 1,566 is a rare bird among galaxies: Gas and dust are still falling into the supermassive black hole at its center, fueling powerful outbursts of radiation that, in shorter wavelengths of light, make the galaxy’s center blaze brighter than all the rest of its stars combined.

Of the thousands of galaxies astronomers have found, cataloged, and studied so far — and the tens of billions in the universe — only about 10 percent have actively-feasting supermassive black holes at their centers. And NGC 1,566 is the second-brightest of these. At 40 million light years from Earth, it’s also one of the closest, making it a prime target for astronomers.

Hubble’s Wide Field Camera captured a near-infrared view of NGC 1,566 back in 2014, which revealed long, swirling arms ablaze with stars and laced with dark strands of interstellar dust. Even in visible and near-infrared light, the galaxy’s core is bright.

EPFL

According to a report by Euronews, researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have discovered a way to create transparent photosensitizers, molecules that can be activated by light and adsorb light across the entire visible light spectrum. Previous versions of DSCs were largely dependent on direct sunlight.

Billionaires are investing in brain-computer-interface systems. Here’s why

Posted by in categories: computing, neuroscience

The technology has significantly progressed in the past 50 years.

Earlier this month, we reported that Bill Gates and Jeff Bezos-backed foundations (Gates Frontier and Bezos Expeditions) joined other companies.

Virtual reality can work for those with one functional eye

Posted by in categories: internet, virtual reality

Modern-day headsets and apps could be the key.

Virtual reality (VR) may soon be the way we use the internet. There are misconceptions about who can and cannot use the technology. Trying out headsets and apps is a great way to know if the technology suits your needs.

If you or someone you know only has one functional eye, and this has been keeping you away from exploring the world of virtual reality, then here’s a little surprise for you. VR experiences are not majorly affected if you do not use both of your eyes.

Ancient Mars did not have atmospheric oxygen, claims new research

Posted by in category: space

That does not mean the planet did not have life.

A new experimental study conducted by Washington University in St. Louis is defeating any hope that scientists have had that atmospheric oxygen once existed on the Red Planet, according to a press release by the institution published on Thursday.

Instead, the scientists have found that under Mars-like conditions, manganese oxides can be readily formed without any presence of atmospheric oxygen.
