Selected dog breeds with most breathing trouble identified in new study
2026-02-18
In short-skulled (brachycephalic) dogs, a very flat face, collapsing nostrils, and a plump physique are associated with difficulty breathing, with Pekingeses and Japanese Chins at especially high risk, according to a study published February 18, 2026 in the open-access journal PLOS One by Francesca Tomlinson from the University of Cambridge, United Kingdom, and colleagues.
The adorable, squished-flat faces of dogs like Bulldogs and Pugs can come at a price. The shortened skull shape is called brachycephaly, and can produce a condition ...
Interplay of class and gender may influence social judgments differently between cultures
2026-02-18
Certain markers of high status may more strongly boost attitudes towards women versus men, and low status markers may more strongly worsen attitudes towards men versus women—with both findings more pronounced in countries with more conservative gender norms. Marie Isabelle Weißflog of Ruhr-Universität Bochum, Germany, and the University of York, U.K., and colleagues present these findings in the open-access journal PLOS One on February 18, 2026.
Within society, some people receive unequal rights, opportunities, and access to resources. Social psychologists ...

An “electrical” circadian clock balances growth between shoots and roots
2026-02-18
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 ...
Largest study of rare skin cancer in Mexican patients shows its more complex than previously thought

Genetic ancestry may play a key role in how acral melanoma, a rare and aggressive type of skin cancer, develops and behaves, with important implications for diagnosis and treatment, new research shows.
Researchers at the Wellcome Sanger Institute, National Autonomous University of Mexico (UNAM) and their collaborators analysed the genetic makeup of over 100 acral melanoma tumours from Mexican patients to understand how this cancer develops, including studying how ancestry influences tumour biology. They uncovered that acral melanoma varies, with three groups ...
Colonists dredged away Sydney’s natural oyster reefs. Now science knows how best to restore them.
2026-02-18
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 ...
Joint and independent associations of gestational diabetes and depression with childhood obesity
2026-02-18
About The Study: In this cohort study, both prenatal depression and gestational diabetes were associated with childhood obesity risk, with larger effect sizes observed for gestational diabetes. Children exposed to both conditions had the greatest risk, although associations appeared additive rather than synergistic. These findings underscore the need for universal prenatal screening and risk stratification, along with targeted interventions for children exposed to these conditions.

New plastic material could solve energy storage challenge, researchers report
2026-02-18
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
2026-02-18
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
2026-02-18
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
2026-02-18
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:

Major heart attack study reveals ‘survival paradox’: Frail men at higher risk of death than women despite better treatment
2026-02-18
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
2026-02-18
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 ...
