Soda tax reduces consumption among boys but not girls

A new study by Cornell University researchers found that taxes on soda reduce consumption among adolescent boys, but not girls. The study analyzed data from Mauritius and Maldives and found that the tax decreased the likelihood of boys consuming soda, but had no impact on their frequency or body mass index.

What’s the skinny on those pandemic pounds?

A large US survey found that adults gained weight during the COVID-19 pandemic due to changes in behavior such as increased snacking and alcohol intake. The analysis of more than 3.5 million adults also showed a 3% increase in obesity prevalence, with significant changes in exercise participation, sleep duration, and cigarette smoking.

New study reveals insights into how early immune response defines severity of COVID-19

A new study by Princeton University researchers reveals that macrophages, a type of immune cell, are crucial in the early immune response to SARS-CoV-2. The study used humanized mice with human lung tissue and blood stem cells to investigate the role of macrophages and identified specific genes associated with an effective antiviral re...

Earliest record of a candidate aurora found in Chinese annals

A recent study published in Advances in Space Research has identified the earliest record of a candidate aurora in an ancient Chinese text, dated to 977-957 BCE. The 'five-coloured light' mentioned in the Bamboo Annals is consistent with a large geomagnetic storm and provides valuable insights into space weather variability.

Electronic alert improves guideline adherence for heart failure treatment

A new study found that customized digital alerts via an electronic health record system significantly increased the number of guideline-directed medications prescribed for heart failure patients. The alerts improved medication use by over a quarter of patients, translating to one medication addition per every 14 alerts received.

Cleveland Clinic-led trial finds that experimental ‘gene silencing’ therapy reduces lipoprotein(a), an important risk factor of heart disease, by up to 98%

A Cleveland Clinic-led trial found that an experimental 'gene silencing' therapy significantly reduced blood levels of lipoprotein(a), a key driver of heart disease risk, by up to 96%-98%. The therapy targets the gene responsible for Lp(a) production and has shown strong efficacy with no major safety concerns reported.

Cutting salt intake shows some benefits for people with heart failure

The SODIUM-HF trial found that reducing sodium intake for one year improved quality of life and slowed heart failure progression in patients. However, it did not significantly reduce major adverse events or hospitalizations. The study suggests that individualized recommendations may be beneficial for certain patients.

Blueberry extract may aid wound healing

Researchers found that a blueberry phenolic extract improved vascularization and cell migration in live wounds, leading to a 12% increase in wound closure. The study suggests wild blueberries have the potential to enhance wound healing, particularly for patients with chronic wounds.

Making a ‘sandwich’ out of magnets and topological insulators, potential for lossless electronics

Researchers create a quantum anomalous Hall insulator by stacking a ferromagnetic material between two 2D topological insulators, enabling room-temperature lossless transport. The new architecture could lead to ultra-low energy future electronics or topological photovoltaics.

Hold the salt: Study reveals how reducing sodium intake can help patients with heart failure

A study of 806 patients with heart failure found that reducing sodium intake improved symptoms such as swelling, fatigue, and coughing. However, it had no effect on rates of death, hospitalization, or emergency department visits. The researchers recommend a lower sodium intake limit for heart failure patients.

Efficient electrocatalytic reduction of nitrate to nitrogen gas: promising way to remove nitrogen from water

Scientists have developed an efficient electrocatalytic material that can selectively convert nitrate into nitrogen gas, reducing total nitrogen levels in water. The material, featuring a cubic Cu2O film with (111) orientation, shows high selectivity and efficiency towards N2 production.

Deterministically integrated manipulation of magnetic skyrmions achieved in nanostructured device

Researchers successfully integrated manipulation of magnetic skyrmions using electrical currents, enabling operations such as writing, erasing and addressing a single skyrmion at room temperature. The achievement demonstrates the potential of skyrmion-based racetrack memories with low power consumption.

Periodic volcanism triggered multiple Jurassic extinctions

A new study provides strong evidence that periodic volcanic activity in the Karoo province triggered multiple Jurassic extinctions. The research reveals that volcanism occurred over a longer period than previously thought, with three distinct stages of activity, and had a significant impact on the environment.

Wildfire smoke exposure in early pregnancy affects infant monkey behavior

A new study found that infant monkeys conceived while their mothers were exposed to wildfire smoke showed increased inflammation, memory deficits, and a more passive temperament compared to those conceived later. The effects suggest that some component of wildfire smoke can act as a teratogen, affecting fetal development.
