The forerunners of dinosaurs and crocodiles in the Triassic period were able to migrate across areas of the ancient world deemed completely inhospitable to life, new research suggests.   In a paper published in Nature Ecology and Evolution today (11th June), researchers from the University of Birmingham and University of Bristol have used a new method of geographical analysis to infer how these ancestral reptiles, known as archosauromorphs, dispersed following one of the most impactful climate events the Earth has ever seen, the end-Permian mass extinction.   The first archosauromorphs, some resembling modern reptiles and many ...

Imagine you’re walking to work when the unspeakable occurs: Your favorite coffee shop — where you stop every day — is closed. You groggily navigate to a newly opened coffee shop a couple blocks away, which, you’re pleased to discover, actually makes quite a good morning brew. Soon, you find yourself looking forward to stopping at the new location instead of the old one. That switch probably alters more than just your morning routine. Each time you visit that new coffee shop, the ...

A team of Korean scientists has developed an innovative green technology that transforms plastic waste into clean hydrogen fuel using only sunlight and water. Researchers at the Institute for Basic Science (IBS) Center for Nanoparticle Research, led by Professor KIM Dae-Hyeong and Professor HYEON Taeghwan of Seoul National University, announced the successful development of a photocatalytic system that produces hydrogen from PET bottles. The key innovation lies in wrapping the photocatalyst in a hydrogel polymer, which helps it float on water and stay active even under harsh environmental ...

Brain cell discovery may explain excessive hunger Researchers identify “meal memory” neurons in laboratory rats that could explain why forgetting lunch leads to overeating. Scientists have discovered a specific group of brain cells that create memories of meals, encoding not just what food was eaten but when it was eaten. The findings, published today in Nature Communications, could explain why people with memory problems often overeat and why forgetting about a recent meal can trigger excessive hunger and lead to disordered eating. During eating, neurons in the ventral hippocampus region of the brain become active and form what the team of researchers call ...

A new study from Karolinska Institutet involving over a million women links difficult childhood experiences to the risk of being diagnosed with endometriosis later in life. The study shows a link between childhood exposure to violence and a twofold increase in the risk of developing this gynaecological disease. Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus. These cells attach to the abdominal lining, uterus, ovaries or other organs and form endometriosis lesions. The lesions react to ...

CLEVELAND—Pancreatic cancer has a five-year survival rate of just 13%, making it the deadliest cancer, according to the American Cancer Society. It typically causes no symptoms until it has already metastasized. Surgery, radiation and chemotherapy can extend survival, but rarely provide a cure. Now, researchers at Case Western Reserve University and Cleveland Clinic are developing vaccines targeting pancreatic cancer that could eliminate the disease, leaving a patient cancer-free. So far, the vaccines have achieved dramatic results ...

For the first time, scientists have used Earth-based telescopes to look back over 13 billion years to see how the first stars in the universe affect light emitted from the Big Bang.  Using telescopes high in the Andes mountains of northern Chile, astrophysicists have measured this polarized microwave light to create a clearer picture of one of the least understood epochs in the history of the universe, the Cosmic Dawn. “People thought this couldn’t be done from the ground. Astronomy is a technology-limited field, ...

The number of armed conflicts in the world reached a historic high in 2024. This is shown by new data from the Uppsala Conflict Data Program (UCDP) at Uppsala University. Despite a marginal decrease in total fatalities, targeted violence against civilians increased significantly. UCDP recorded 61 active conflicts involving at least one state in 2024, up from 59 the previous year and the highest number since statistics began in 1946. Eleven of these reached the level of war, defined as a conflict causing at least 1,000 battle-related deaths in a year. This is the highest number since 2016. Despite ...

Precision gene editing is crucial for treating genetic diseases, as it enables targeted correction of specific mutations. A Korean research team has become the first in the world to significantly enhance the low efficiency of a key genome editing mechanism—known as homologous recombination (HR)—by inducing autophagy, a natual process whthin cells. Dr. Hye Jin Nam’s team at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with Professors Dong Hyun Jo and Sangsu Bae at ...

CLEVELAND, Ohio (June 11, 2025)—Nomograms have a strong reputation as reliable predictive models that simplify statistical prediction models and guide personalized treatment to formulate preventive measures for various diseases. Through a new study, a nomogram was developed and validated to predict the risk of patients with epithelial ovarian cancer developing deep vein thrombosis. Results of the study are published online today in Menopause, the journal of The Menopause Society. Although ovarian cancer is not one of the more common types of cancer (especially compared with breast or lung cancer), it is serious. It is the fifth-leading ...

Cells taken from the lungs of people with chronic obstructive pulmonary disease (COPD) have a larger accumulation of soot-like carbon deposits compared to cells taken from people who smoke but do not have COPD, according to a study published today (Wednesday) in ERJ Open Research [1]. Carbon can enter the lungs via cigarette smoke, diesel exhaust and polluted air.   The cells, called alveolar macrophages, normally protect the body by engulfing any particles or bacteria that reach the lungs. But, in their new study, researchers found that when these cells are exposed to carbon they grow larger and encourage inflammation.   The research was led by Dr James Baker and Dr Simon Lea ...

When it comes to advanced cancer or Alzheimer’s disease, over half of doctors would consider assisted dying for themselves, but preferences seem to vary according to their jurisdiction’s legislation on euthanasia, reveal the results of an international survey, published online in the Journal of Medical Ethics. And most say they would prefer symptom relief rather than life sustaining treatment for their own end of life care, indicate the responses.  Previously published research suggests that doctors’ views on their own end of life care inform their clinical practice, and that their perceptions of their patients’ treatment wishes ...

There’s an urgent need to quantify the role of fungal toxins (aflatoxins), found on agricultural crops, such as maize and peanuts (groundnuts), in the escalating rates of liver cancer in Ghana, as well as elsewhere in Africa and Asia, concludes a commentary published in the open access journal BMJ Global Health. Maize and peanuts are dietary staples in many Asian and African countries. And with one of the highest rates of liver cancer in Africa, at 16/100,000 of the population. Ghana represents a critical case study in furthering international ...

CAMBRIDGE, MA -- For many patients with schizophrenia, other psychiatric illnesses, or diseases such as hypertension and asthma, it can be difficult to take their medicine every day. To help overcome that challenge, MIT researchers have developed a pill that can be taken just once a week and gradually releases medication from within the stomach. In a phase 3 clinical trial conducted by MIT spinout Lyndra Therapeutics, the researchers used the once-a-week pill to deliver a widely used medication for managing the symptoms of schizophrenia. They found that this treatment regimen maintained consistent levels of the drug in patients’ ...

Smartphone apps that track menstrual cycles are a “gold mine” for consumer profiling, collecting information on everything from exercise, diet and medication to sexual preferences, hormone levels and contraception use, according to a University of Cambridge report. A report from Cambridge’s Minderoo Centre for Technology and Democracy argues that the financial worth of this data is “vastly underestimated” by users who supply profit-driven companies with highly intimate details in a market lacking in regulation. The report’s authors caution that cycle tracking app (CTA) ...

Memory problems have long been considered the primary hallmark of dementia, but a team of researchers is now challenging this view. They argue that changes in sensory perception – from vision to balance – may be equally important indicators that many healthcare providers are currently missing. According to experts, current approaches to the care and support of people with dementia need an overhaul, relying too heavily on the assessment of memory functions, when the condition also impairs taste, touch, balance, hearing, or vision. Professor Andrea Tales, Professor of Dementia ...

An intensive low-energy diet programme, similar to the NHS Type 2 Diabetes Path to Remission, significantly improved eating disorder symptoms in people with type 2 diabetes and excess weight who were at risk of developing eating disorders, according to a University of Oxford study published today in The Lancet Psychiatry. Participants enrolled in a total diet replacement (TDR) programme experienced significant improvements in eating disorder symptoms which persisted six months after the programme finished when participants had regained some weight. This directly addresses a research gap highlighted by recent National Institute for Health and Care Excellence (NICE) guidance on the use of ...

Whether it’s a personal challenge, for charity, or on your bucket list, marathons are one of the most sought-after goals for amateur and recreational runners worldwide.   Now, a world-first study from the University of South Australia and the University of North Dakota suggests that a person’s marathon potential may be identified through a simple check of their hands.   In a meta-analysis of 22 studies (representing 5293 participants and 12 countries) researchers found that a lower digit ratio – when a person’s ring finger is longer than their index finger – is a biomarker of cardiorespiratory fitness, ...

SAN ANTONIO — June 10, 2025 — Southwest Research Institute’s Dr. Craig DeForest discussed the latest accomplishments of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission during a media event at the 246th American Astronomical Society meeting in Anchorage, Alaska. As the spacecraft constellation completes commissioning, early PUNCH data showed coronal mass ejections, or CMEs, as they erupted from the Sun and traveled across the inner solar system. “These preliminary movies show that PUNCH can actually track space weather across ...

In brief: Climate behavior gap: Most Americans overrate the climate impact of actions like recycling and underrate high-impact choices like skipping long flights or eating less meat, a new study finds. Spillover risk: Interventions that focus only on personal behavior can reduce willingness to engage in collective climate action, such as voting or protesting. What works: Active learning boosts climate literacy and commitment to impactful lifestyle changes – but must be paired with strategies that also support collective action. Many Americans misjudge which personal behaviors have the biggest impact ...

California’s Central Valley — one of the nation's most critical agricultural regions and home to over 1.3 million people — is prone to flooding. Mapping the extent of winter floods has been challenging for experts, however, because clouds can obscure the view of satellites. Recent efforts to improve satellite flood mapping have been incorporated into a new study that offers insight into where winter flooding is occurring and inform how floodwaters can be used to replenish depleted aquifers.  The research, published June 4 in ...

A new study from Emory University addresses the growing global crisis of antibiotic-resistant infections. Many of these drug-resistant bacteria are spread through hospitals, and there are few antibiotics available for treatment. The study, published in PNAS, looks at a particular bacterium called Acinetobacter baumannii, which is highly infectious, spread mostly in hospitals and typically infects immunocompromised patients. The researchers employed an entirely new strategy to identify weaknesses specific to resistant bacteria and then target these weaknesses with an alternate drug. They found that fendiline, a drug that acts as a calcium channel blocker and ...

UNIVERSITY PARK, Pa. — How educators acquire and implement learnings from their students can play a critical role in environmental education, according to a new study from researchers in the Penn State Department of Recreation, Park, and Tourism Management. The researchers found a role reversal between teachers and students, as environmental educators reported improvement in teaching and leadership skills after learning from the existing knowledge and experiences of students in an environmental education program, demonstrating ...
