Not so dark with Alena Tensor: Math framework could explain dark matter without invisible particles

Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, ...

A built-in 'hairpin' mechanism in CRISPR-Cas13 prevents rogue RNAs

The CRISPR-Cas gene-editing system has long been the focus of research as a promising tool in genome editing. However, the emphasis has been on its underlying mechanisms and nucleases. In contrast, little research has examined ...

Torsion balances set strongest direct limits yet on ultralight dark matter

Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most past experiments have focused on heavier dark matter candidates, while much lighter dark matter, ...

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.

Quantum simulations tackle photon polarization flip, but today's hardware falls short

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of countless experiments and agreeing ...

Could dark matter be made of black holes from a different universe?

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could explain dark matter, one of the biggest unsolved questions in cosmology.

The quietest place we've ever listened from

We have been searching for signals from other civilizations for over sixty years. Radio telescopes on Earth have swept the sky, listened patiently, and found nothing but silence. It is a search that demands extraordinary ...

A new fruit wash removes pesticides and extends shelf life

University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and ...

From ship wakes to soft tissues: Exploring fluid and solid surface-wave physics

A new study by scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that when a pressure disturbance moves across an ultrasoft elastic material, such as a gel or a biological tissue, ...

Gray whales are dying in San Francisco Bay at an alarming rate. This isn't normal

At least six gray whales have died in San Francisco Bay from mid-March to early April 2026. These deaths follow a pattern over the past few years, and they are raising concerns among marine biologists like us that 2026 is ...
