Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found. The result means that although modern planes emit less carbon than older aircraft, they may be contributing more to climate change through contrails. Led by scientists at Imperial College London, the study highlights the immense challenges the aviation industry faces to reduce its impact on the climate. The new study also found that private jets produce more contrails than previously thought, ...

The world’s seabeds are little explored, and the knowledge we have is patchy. Using remotely operated underwater vehicles to learn about seabeds is expensive, requires certain weather conditions, and is difficult in deep, remote, and offshore habitats. To circumvent these challenges, researchers in Australia have now enlisted endangered Australian sea lions (Neophoca cinerea) to carry cameras. The resulting videos allowed the researchers to identify previously unmapped benthic habitats used by the sea lions on the continental shelf. They published their results in Frontiers in Marine Science. “Using ...

ARLINGTON, Va. (August 7, 2024) — Family members of patients recently discharged from the hospital may have a higher risk of getting an antibiotic-resistant infection, often called a superbug, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in the community spread of resistant bacteria, according to study in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. When recently hospitalized patients were diagnosed with the superbug — Methicillin-resistant ...

With rising global temperatures due to global warming, the risk of heat strokes has increased and is expected to grow even further. This is particularly troubling for athletes participating in competitive sports. In tennis, multiple matches are played daily, lasting up to five hours. Playing such matches in sweltering conditions could be highly detrimental. The Tokyo Olympic Games in 2021 faced extremely hot conditions with many players calling for appropriate countermeasures. Consequently, the International Tennis Federation (ITF) formulated and issued the “Extreme Weather Policy” at the Tokyo Olympics to manage matches based ...

Everyone gets sleepy at work from time to time, especially after a big lunch. But for people whose jobs involve driving or working with heavy machinery, drowsiness can be extremely dangerous — if not outright deadly. Drowsy driving contributes to hundreds of fatal vehicle accidents in the U.S. each year, and the National Safety Council has cited drowsiness as a critical hazard in construction and mining. To help protect drivers and machine operators from the dangers of drifting off, engineers at the University of California, Berkeley, have created prototype earbuds that can detect the signs of drowsiness ...

Boston – Vorasidenib has been approved by the U.S. Food and Drug Administration (FDA) for patients with Grade 2 gliomas with IDH1 or IDH2 mutations.  Based on evidence from the INDIGO clinical trial, a global phase 3, double-blinded, randomized clinical trial, vorasidenib more than doubled progression-free survival and delayed the need for treatment with radiation and chemotherapy for patients with Grade 2 IDH-mutant glioma after surgery to remove the tumor. INDIGO was the first phase 3 clinical trial of a molecularly targeted therapy for IDH-mutant glioma. “The INDIGO trial ...

It may now be time to ban artificial stone—a firm favourite for kitchen worktops in the UK— to ward off the incurable lung disease caused by its manufacturing and fitting, say a team of doctors in the journal Thorax after treating the first 8 cases of artificial stone silicosis reported in the UK. Silicosis is caused by breathing in crystalline silica dust, and millions of people around the world are at risk of developing it as a result of their jobs in mining, quarrying, stone-cutting ...

The UK and the European Union should follow Australia’s lead and ban the kitchen worktop favourite and cause of irreversible and rapidly progressive lung disease—artificial stone siliicosis—urge researchers in an editorial, published online in Occupational & Environmental Medicine. And until a ban comes into force, all possible control measures should be legally enforced to minimise workers’ exposure to the harmful crystalline silica dust generated during its manufacture and fitting, insist the authors. Artificial stone (also known as engineered stone) is widely used for surfaces ...

Renewed efforts to reduce child poverty in England between now and 2033, such as removing the 2-child limit on child benefit, would significantly boost several aspects of child health and narrow health inequalities across the country, finds research published online in the Journal of Epidemiology & Community Health. Tackling it would substantially cut the number of infant deaths and children in care, as well as rates of childhood nutritional anaemia and emergency admissions, with the most deprived regions, especially ...

The International Olympic Committee (IOC) should cut its ties with Coca Cola in the best interests of athletes, spectators, and the planet, urge Trish Cotter and Sandra Mullin of the international public health organisation, Vital Strategies, in an editorial to be published shortly in the open access journal BMJ Global Health.* The company’s sponsorship forces athletes to implicitly endorse unhealthy sugary drinks and provides Coca Cola with elite access to political and corporate leaders to exert its influence, insist the authors. Coca Cola has sponsored the Olympic Games for almost 100 years, they note. And there’s ...

Today, Bloomberg Philanthropies announced a gift of $5 million in seed funding to support the creation of the Xavier Ochsner College of Medicine (XOCOM), a newly established medical school in New Orleans founded by Xavier University of Louisiana and Ochsner Health.

A recent study by László Zsolt Garamszegi from the Institute of Ecology and Botany, Centre for Ecological Research, Hungary, and Niclas Kolm from the Department of Zoology, Stockholm University, Sweden, challenges the long-held notion that domestication is the primary driver of reduced brain size in domesticated animals, specifically dogs. The study employs a phylogenetic comparative method to analyze whether the domesticated dog (Canis familiaris) exhibits a uniquely small brain relative to its body size compared to other canid species. The prevailing belief has been that domestication leads to a significant ...

By recruiting the immune system to combat tumor cells, immunotherapy has improved survival rates, offering hope to millions of cancer patients. However, only about one in five people responds favorably to these treatments. With a goal of understanding and addressing immunotherapy’s limitations, researchers at Washington University School of Medicine in St Louis have found that the immune system can be its own worst enemy in the fight against cancer. In a new study in mice, a subset of immune cells – type 1 regulatory T cells, or Tr1 cells – did its normal job of preventing the immune system from overreacting but did so while inadvertently restraining immunotherapy’s ...

For thousands of years, plants have evolved in the presence of wildfires in the Cerrado, Brazil’s savanna-like biome. Scientists at São Paulo State University (UNESP) studied the effect of smoke on seed germination for 44 plant species typical of the Cerrado, as reported in an article published in Plant Ecology, where they stress that their findings could be used to optimize the restoration of degraded areas. The study was conducted by PhD candidate Gabriel Schmidt Teixeira Motta under the supervision of Rosana Marta Kolb, a professor at UNESP. “Previous studies focused on the effect of smoke on only a few ...

NEW YORK, NY (July 29, 2024) ---- Underrepresentation of racial and ethnic minority populations in cancer clinical trials persists partly because translation and interpretation services and resources are unavailable or inadequate in the United States, according to a Children’s Oncology Group (COG) study led by Columbia University School of Nursing. The updated study was published online in the Journal of the National Cancer Institute Cancer Spectrum on July 25, 2024 and will appear in the August 2024 journal issue.  In 2019, 68 million people in the United States were reported to speak a language other than ...

Obesity is an epidemic in the United States. It has been increasing among adults of all races and ethnicities over the last two decades; however, obesity is higher among Non-Hispanic Black adults, Hispanic adults, and American Indian or Alaska Native adults, than their White and Asian counterparts, according to the National Institutes of Health. Adults with lower income also have higher risk of obesity than those with a high income.  A George Mason University College of Public Health team of interprofessional researchers analyzed the last five years ...

Blockchain technology has become one of the most hyped advancements in recent years, but there hasn’t been a clear understanding of the potential trade-offs for its use by multinational corporations (MNCs). A new study published in the Global Strategy Journal provides a better understanding of blockchain merits and drawbacks by focusing on three particular applications of the technology in this sector: financial transactions, collaboration, and data analytics. The study, “A perspective on three trade-offs of blockchain technology for the global strategy of the MNC,” was authored by Tuuli Hakkarainen of the University of Liverpool, Anatoli Colicev of the University ...

Increasing ventilation in child-care settings may not always be effective at preventing flu virus spread, according to a new study published by a team of researchers at Emory University, University of Pittsburgh School of Medicine, and Virginia Tech. The spread of flu viruses is commonly studied in animal models that don’t mimic the real-life scenarios of the human experience, making it difficult to evaluate strategies that will be effective in common places where disease spreads rapidly, such as childcare settings. As reported online and in a coming print issue of the journal Proceedings of the National ...
