Liquid-like histone H1 'glues' nucleosomes, reshaping how DNA compacts

DNA inside the nucleus is not packed as a rigid regular fiber—linker histone H1 dynamically binds and loosely "glues" nucleosomes together, creating a dynamic, fluid organization that can still support essential genome functions.

Electrofluidic fiber muscles could enable silent robotic systems

Muscles are remarkably effective systems for generating controlled force, and engineers developing hardware for robots or prosthetics have long struggled to create analogs that can approach their unique combination of strength, ...

Without the right tests, the best medicines make no difference

A new analysis from UC San Francisco argues that diagnostics—medical tests that match patients to the appropriate treatment—are being overlooked both in the United States and around the world. This is slowing progress against ...

How an overactive immune system can drive cancer

The immune system is designed to protect us against viruses and bacteria. In autoimmune diseases, however, the immune system instead attacks the body's own cells. Conditions such as systemic lupus erythematosus (lupus) and ...

What if dark matter came in two states?

The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...

It's OK to love all the bees (the honey bees, too)

North America's bee populations are in trouble, but don't blame the honey bees. While some people argue that an overabundance of managed honey bees—those raised to help pollinate crops and produce honey—is causing native ...

Study rethinks the dropout-crime connection

Dropping out of high school has been linked to higher rates of delinquency and lower socioeconomic status, but thinking of high school dropouts collectively, as one group, is a flawed belief that could be affecting interventions. ...

This giant virus just gave up its atomic blueprint

A research group has successfully determined, for the first time in the world, the capsid (outer shell) structure of Melbournevirus—a member of the giant virus family—at a resolution of 4.4 Å using cryo-electron microscopy ...

Twin NASA control rooms support Artemis safety, success

Twin control rooms at NASA's Marshall Space Flight Center in Huntsville, Alabama, are actively supporting real-time mission operations in lunar orbit as part of the agency's Artemis II mission, helping ensure astronaut safety ...

Emperor penguins listed as endangered species: IUCN

The emperor penguin has been declared an endangered species as climate change pushes the icon of Antarctica a step closer to extinction, the global authority on threatened wildlife announced on Thursday.

New study reveals the depth of children's nuclear anxiety

As geopolitical tensions rise globally, a new study published in Critical Studies on Security warns that the shadow of the "mushroom cloud" is weighing heavily on the next generation. The research paper, titled "Mushrooms, ...

Study of 633,000 people links loneliness to suicidal thoughts

Loneliness plays an important role in the development of suicidal ideation, thoughts of ending one's life, which precedes nearly every suicidal death, according to a study by researchers at Vanderbilt Health. Their findings, ...

A big step toward safe, reversible male contraception

Cornell scientists have taken a major step toward developing a safe, reversible, long-acting and 100% effective nonhormonal male contraceptive, considered the holy grail of male contraception. A proof-of-principle study in ...

Scientists reveal a new way cancer cells survive DNA damage

A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential than researchers realized. Scientists at Scripps Research have discovered that the enzyme Pol theta ...

How childhood dementia begins in brain cells

An Australian-led international research collaboration has delivered a promising breakthrough in the quest to better understand and treat childhood dementia. Recently published in the journal Nature Communications, the study ...

Smart MRI molecules developed to detect and treat cancer

Researchers at NYU Abu Dhabi have developed smart molecules that can both detect and treat cancer, offering a safer and more precise approach to care. The research, published in the Journal of the American Chemical Society, ...

A color-changing phosphor can encode information

A new synthetic molecule switches between emitting green and blue light after application of a solvent or mild heat. The color-changing phosphor can be leveraged for a two-layered information encoding platform, according ...

What it takes to keep astronauts safe in deep space

The Artemis II mission launches this week as a first step toward returning to the moon and reaching Mars. Materials scientist Debbie Senesky explains the material tech that makes these missions possible.
