An “electrical” circadian clock balances growth between shoots and roots

Bellaterra (Barcelona), February 18, 2026 - Plants don’t just respond to light and water, they also run on an internal daily timekeeper known as the circadian clock. Researchers have now discovered that the plant circadian clock can regulate electrochemical signals in specific cells that help determine whether growth is invested above ground or below ground. In a study led by Paloma Mas, CSIC Research Professor at the Centre for Research in Agricultural Genomics (CRAG), and published in the leading scientific journal ...

Colonists dredged away Sydney’s natural oyster reefs. Now science knows how best to restore them.

New research has identified optimal design for artificial habitats to support restoration of oyster reefs, based on a detailed understanding of natural oyster reef geometry. Published in the global journal Nature, the Sydney-based study shows the complex shapes of natural oyster reefs are not random – their structure and arrangement optimise the establishment and survival of developing oysters and their protection from predators. Oysters are really “ecosystem engineers”, building their own reefs made up of living oysters and the discarded shells of previous generations, explains lead author of the study, Dr Juan Esquivel-Muelbert ...

New plastic material could solve energy storage challenge, researchers report

UNIVERSITY PARK, Pa. — In the race to lighter, safer and more efficient electronics — from electric vehicles to transcontinental energy grids — one component literally holds the power: the polymer capacitor. Seen in such applications as medical defibrillators, polymer capacitors are responsible for quick bursts of energy and stabilizing power rather than holding large amounts of energy, as opposed to the slower, steadier energy of a battery. However, current state-of-the-art polymer capacitors cannot survive beyond 212 degrees Fahrenheit (F), which the air around a typical car engine can hit during summer months ...

Mapping protein production in brain cells yields new insights for brain disease

The brain’s ability to do everything from forming memories to coordinating movement relies on its cells producing the right proteins at the right time. But directly measuring this protein production, known as translation, across different types of brain cells has been a challenge. Now, scientists at University of California School of Medicine, Scripps Research and their colleagues have developed a technology that reveals which proteins are generated by individual brain cells. The team used their method — called Ribo-STAMP — to create the first maps of protein production across ...

Exposing a hidden anchor for HIV replication

The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it.  More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually evolve as HIV mutates. During the acute stage of infection, a single human cell can produce as many as 10,000 new HIV particles.  At the University of Delaware, Professor Juan R. Perilla and his research team in the Department of Chemistry and Biochemistry have spent over a decade probing the structure and function of HIV’s protective shell, or capsid, ...

Can Europe be climate-neutral by 2050? New monitor tracks the pace of the energy transition

Researchers at the Complexity Science Hub (CSH) have developed a monitor that tracks how quickly companies are switching to climate-neutral energy – and have applied it in one country. Many firms are making progress; just as many are falling behind. And those firmly entrenched in fossil fuel structures face a particularly steep climb to change course. IN SHORT:  Europe aims to be climate-neutral by 2050, yet actual progress in the economy has so far been barely measurable. The CSH Monitor is the first objective method for measuring the state of the energy transition at the company level. Example – Hungary: The researchers ...

Major heart attack study reveals ‘survival paradox’: Frail men at higher risk of death than women despite better treatment

Pioneering research from the University of Leicester and NIHR challenges the ‘one-size-fits-all’ approach to heart attack care, adding critical nuance to the debate on sex disparities. A groundbreaking new study involving more than 900,000 patients has revealed a "sex-frailty paradox" in heart attack outcomes, challenging the prevailing narrative that high clinical risk is predominantly a female issue.  While considerable focus has rightly been placed on addressing the fact that women are often undertreated compared to men after a heart attack, this new research, published in The Lancet Regional ...

Medicare patients get different stroke care depending on plan, analysis reveals

A first-of-its-kind analysis has revealed significant differences in stroke outcomes and stroke care for patients on government-run traditional Medicare plans versus those on Medicare Advantage, offered by private insurers.   UVA Health researchers found that patients on traditional, or “fee-for-service,” Medicare Part A, B and D plans operated by the government were less likely to have access to certain stroke-preventing care. They were more likely, however, to receive intensive post-stroke care and rehabilitation than those enrolled in Medicare Advantage, where private insurance plans are incentivized to limit more expensive medical care.   Both ...

Natural selection operates on multiple levels, comprehensive review of scientific studies shows

The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. To suggest otherwise can provoke the ire of certain segments of the scientific community, acknowledged Binghamton University Associate Professor Emerita of Biological Sciences Anne Clark. But a bibliometric review of 280 scientific studies shows that natural selection can occur on multiple levels of biological organization simultaneously, and not just in social species. Clark is a co-author of the article “Abundant empirical evidence of multilevel selection revealed by a bibliometric review,” which recently ...
