Phys.org / Hubble identifies a near-invisible galaxy that may be 99% dark matter

In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter and containing ...

Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...

Phys.org / A super stable laser on the moon could guide future lunar missions and improve our timekeeping

Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, ...

Phys.org / Measuring chaos: Researchers quantify the quantum butterfly effect

For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of ...

Phys.org / How the humble silkworm could help us discover new anti-aging treatments

When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...

Phys.org / The cooling system that lets bees beat the heat when hovering

To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...

Phys.org / First-ever shark recorded in Antarctic waters filmed at 490 meters in near‑freezing water

An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun's rays to illuminate was an unexpected sight.

Phys.org / Indigenous Peoples and locals report a drastic decline in bird size across three continents

Birds currently inhabiting many territories across Africa, Latin America and Asia are, on average, considerably smaller than those that predominated in 1940. This is the conclusion of an international study led by the Institute ...
