A study of children in Tarragona, Spain, found that higher prenatal exposure to air pollution (PM10 and PM coarse particles, NO2, and NOx gases) was associated with slightly higher teacher-reported ADHD symptom scores in school-age participants. However, this study found no association between exposure to air pollution and clinical diagnosis of ADHD. The paper is Research on psychopathology in children and adolescents. Air pollution is the presence of harmful substances such as gases, particles, smoke, and chemical pollutants in the air. They can come from natural sources such as traffic, factories, power plants, heating systems, agriculture, fires, and sandstorms. Air…

When climate scientists first tried to estimate how airborne microplastics contributed to global warming, they modeled it as colorless, essentially transparent beads floating in the wind. This is the simplest assumption and, for many years, the only one with sufficient data behind it. Real plastic in the air is rarely transparent. It is stained, printed and weathered. And a new study found that these colored particles absorb about 75 times more sunlight than transparent particles. That gap is large enough to draw plastics into a conversation that scientists are only just beginning to have.How do microplastics become airborne?Plastic…

In response to the rapidly evolving Ebola outbreak, the Trump administration has imposed a ban on foreign travelers who have been to the Democratic Republic of the Congo, Uganda, and South Sudan from entering the United States in the past 21 days, according to a new order issued by the Centers for Disease Control and Prevention. The order is aimed at stopping the flow of Ebola cases into the United States and applies to U.S. citizens and military personnel, regardless of their national origin, and anyone who has been in those countries in recent weeks, except for those specifically exempted…

A new study suggests that engaging in personal religious activities, such as praying and reading scripture, tends to reduce the spikes in blood pressure during stressful situations. The results of this study indicate that while an individual’s religious practices may provide a protective buffer against the physical harm of acute stress, general spiritual feelings are unlikely to confer similar physical benefits. This study was recently published in the journal religion, brain, behavior. Cardiovascular disease remains the leading cause of death worldwide. Psychological stress is recognized as a risk factor for developing heart disease, comparable to physical factors such as smoking,…

After showing impressive Phase 3 results last fall, AstraZeneca’s bet on Cincor Pharma and its aldosterone synthase inhibitor (ASI) baxdrostat continues to pay off. The FDA has given full approval to AZ’s Baxdrostat (now named Baxfendi) as the first ASI approved to treat patients with hypertension in the United States.According to a May 18 press release, the FDA has approved the drug’s use in conjunction with other antihypertensive therapies for adults whose high blood pressure is not adequately controlled. AZ estimates that about half of people living with high blood pressure in the United States are already taking high blood…

In the past 18 months, Merck and Cologne Biotech have secured four approvals in China for the TROP2-directed antibody-drug conjugate (ADC) sacituzumab tilmothecan (sac-TMT). And now, after meeting the primary endpoint in a Phase 3 trial in select patients with advanced or recurrent endometrial cancer, the companies are taking steps to obtain approval for sac-TMT in other indications. In a prespecified interim analysis, sac-TMT resulted in statistically significant and clinically meaningful improvements in overall survival (OS) and progression-free survival (PFS) compared to physician’s choice of doxorubicin or paclitaxel chemotherapy. The study also met a key secondary endpoint, objective response rate…

In physics, there are few concepts as familiar or puzzling as time itself. Einstein’s theory of relativity showed that time is neither fixed nor universal. Instead, it changes depending on speed and gravity. But when scientists combine the theory of relativity with quantum mechanics, things get even weirder. Quantum theory suggests that time itself may exist in a superposition. This means that time can flow both fast and slow at the same time. A newly published study suggests that researchers may soon be able to test this strange idea in the lab. The paper, titled “Quantum signature of proper time…

worldwide annual production Plastic usage is predicted to increase to 400 million tonnes in 2022 and double by 2050. Many of the products produced are used once and then thrown away, with more than 30 billion plastic bottles sold each year in the United States alone. Less than 10% of plastic waste is recycled. It is clear that the problem of plastic pollution in terrestrial and marine environments is not going away. This series includes research into the increasing demand for single-use bottled water and considers several approaches to addressing it.According to an industry survey released in 2024, a whopping…

Eli Lilly is setting up a huge manufacturing facility in Houston, but it’s not the only big U.S. drug company eyeing the populous Texas town. Bristol-Myers Squibb is considering building a $1 billion manufacturing facility in Houston that would employ nearly 500 people, according to a filing (PDF) with the state. If the project goes ahead, Bristol will initially build a 600,000-square-foot factory with the possibility of expansion in the future. The company will be located in the Generation Park Management District on the city’s northeast side and will produce pharmaceuticals for domestic and international markets, according to the filing.…

Enhertu’s market conquest continues apace. Daiichi Sankyo and AstraZeneca’s star antibody-drug conjugate, which already has annual sales of $5 billion, has secured FDA approval as a treatment for early-stage breast cancer, further encroaching on the territory of Roche’s Kadcyla. The FDA has simultaneously given Enhertu the go-ahead for both neoadjuvant and postoperative therapy in patients with HER2-positive early-stage breast cancer, the companies announced Friday. The FDA originally aimed to make a decision by July 7, so the adjuvant treatment agreement came nearly two months ahead of schedule. Although early, there are pitfalls with adjuvant labels. Patients who receive Enhertz preoperatively…
