Behind nature's blueprints: Physicists create 'theoretical rulebook' of self-assembly
Inspired by biological systems, materials scientists have long sought to harness self-assembly to build nanomaterials. The challenge: the process seemed random and notoriously difficult to predict.
Cells use Morse code-like rhythms to coordinate growth
Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus where it activates the stress-specific genes to
Coffee as a staining agent substitute in electron microscopy
To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some laboratories are not allowed to use this highly toxic
Doing good pays off: Environmentally and socially responsible companies drive value and market efficiency
This year marks the 20th anniversary of the Principles for Responsible Investment (PRI), launched with United Nations backing in 2006. Today, environmental, social, and governance (ESG) related non-financial information—such as greenhouse gas emissions, pollution control, and

Astrophysicists map how many ghost particles all the Milky Way's stars send towards Earth
They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles that are invisible, incredibly light, and interact only
Scientists are closing in on the Universe’s biggest mystery
Nearly everything in the universe is made of mysterious dark matter and dark energy, yet we can’t see either of them directly. Scientists are developing detectors so sensitive they can spot particle interactions that might occur once in years or even decades. These experiments
Cosmic lens reveals hyperactive cradle of future galaxy cluster
Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, offering a window to study how they all formed. This early "settlement" of galaxies

Repeating fast radio burst shows diverse activity and hints at magnetar origin
Using the upgraded Giant Metrewave Radio Telescope (uGMRT), Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A. Results of these observations shed more light on the activity and properties of this burst. The
Scientists tried to break Einstein’s speed of light rule
Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might behave slightly differently at extreme energies. By tracking ultra-powerful gamma
Are 'new towns' a solution to the housing crisis?
As housing prices continue to rise nationwide—not just in major metropolitan areas, but even in rural locations—there's pressure to create more housing. In Massachusetts, the 2024 Affordable Homes Act calls for 220,000 additional units of affordable housing to be created, but
Heat-inducible promoters show varied expression patterns in sugarcane stems
Inducible promoters provide remarkable utility when sustained transgene expression compromises plant development or agronomic performance.
Washington state overestimates climate law's emission reductions by a long shot
Projects funded by Washington's Climate Commitment Act have not been nearly as effective at reducing greenhouse gas emissions as previously thought, state officials acknowledged this week.
A quantum discovery that breaks the rules of heating
When scientists repeatedly drove a strongly interacting quantum system with laser “kicks,” they expected it to heat up and grow chaotic. Instead, the atoms abruptly stopped absorbing energy and locked into a stable pattern of motion. This strange effect arises from quantum
Jellyfish and Sea Anemones Sleep Just Like Us
Sea anemones and jellyfish don’t have brains, but the way their neurons behave during sleep shows some surprising similarities to humans
Australia heat wave stokes risk of catastrophic bushfires
Firefighters warned millions of Australians of "catastrophic" bushfire dangers on Thursday as they battled multiple blazes stoked by a heat wave blanketing the country.
Trump withdraws US from key climate treaty, deepening global pullback
President Donald Trump's decision to withdraw the United States from a bedrock climate treaty was slammed Thursday by the EU, which vowed to keep tackling the crisis with other nations.
Study suggests taking photos at live events can come at a social cost
At the start of a concert, a voice may come over the speakers warning members of the audience not to take photos or videos of the performance.
Strategy over morality can help conservation campaigns reduce ivory demand, research shows
Research has shown that conservation campaigns could turn the tide on the illegal ivory trade if they focused less on themes of 'guilt' and more on why people want to buy ivory in the first place.
Volcano guides at Mount Etna are protesting over new safety rules
Guides who take tourists to enjoy the striking views of Sicily's Mount Etna are up in arms over tougher restrictions imposed by local authorities after a round of eruptions at the giant volcano in recent weeks.

Just 10 minutes of exercise can trigger powerful anti-cancer effects
A brief, intense workout may do more than boost fitness—it could help fight cancer. Researchers found that just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA repair and shut down cancer growth signals. When these molecules were applied
Scientists find exercise rivals therapy for depression
A large review of studies suggests that exercise can ease depression about as effectively as psychological therapy. Compared with antidepressants, exercise showed similar benefits, though the evidence was less certain. Researchers found that light to moderate activity over
This brain trick makes exercise feel easier
Exercise doesn’t just challenge the body; it challenges how the brain interprets effort. Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like they were working more. Their muscles and hearts worked overtime, but their
