Meta-analysis informed the updated WHO guidelines for treatment of uncomplicated malaria in the first trimester of pregnancy

A new meta-analysis commissioned by WHO informs updated treatment guidelines for uncomplicated malaria in the first trimester of pregnancy. The study finds that artemether-lumefantrine is as safe and possibly more effective than non-artemisinin-based treatments, including quinine, with significant reductions in adverse pregnancy outcomes.

How women can reduce the risk of hip fracture

A new study found that increasing protein intake by 25g a day and drinking regular cups of tea or coffee can reduce the risk of hip fracture in women by up to 14% and 4%, respectively. The study, which analyzed data from over 26,000 middle-aged women, also discovered that underweight women may experience greater reductions in risk.

Consuming a high sodium, low potassium diet can increase the risk of cognitive decline

A new study published in the KeAi journal Global Transitions found that consuming a high sodium, low potassium diet can increase the risk of cognitive decline in elderly people. Participants who replaced 1000mg/day of sodium with an equal intake of potassium showed an average increase of ~1 point on their cognitive test score.

Rutgers researcher creates algorithms to predict arsenic contamination in private wells in New Jersey

A Rutgers researcher has created a machine learning model that can estimate arsenic contamination in private wells without sampling the water. The model identifies geological bedrock type and soil type as primary contributors to higher arsenic concentrations, highlighting the need for targeted well testing programs.

A recent study by the Alliance of Bioversity International and CIAT found that global deforestation proceeded as expected during the COVID-19 pandemic, despite lockdowns. Deforestation rates likely remained unchanged due to persistent dynamics driving forest loss before the pandemic.

Bringing the Kelvin problem solutions to life with the first-ever polymeric Weaire-Phelan structures

A Japanese research team successfully constructed the first polymeric Weaire-Phelan structure, a previously theoretical form predicted to be the most efficient solution for a century-old tessellation problem. The structure was achieved through a novel polymerization-induced phase separation method.

CU Anschutz researchers find less-invasive treatment for certain head and neck cancers

Researchers at CU Anschutz Medical Campus have identified a less invasive way to treat HPV-unrelated head and neck squamous cell carcinomas by combining radiation with immunotherapy. The approach resulted in remarkable success rates, including 75% of patients experiencing major pathological responses or complete responses.

Using math to better treat cancer

Researchers at the University of Waterloo have identified a new method for scheduling radiation therapy that could be up to 22% more effective at killing cancer cells. The algorithm takes into account the differing radiation resistances of stem cells and non-stem cells, allowing doctors to predict how a tumour will respond to treatment.

Green means GO! Ultra-violet means STOP!

Scientists at Osaka Metropolitan University developed a new system to control the behavior of nematode worms using two different light-sensitive proteins called opsins. The researchers found that exposing the worms to white light triggered avoidance behavior, while UV light stopped movement and green light restarted it.

Community pharmacy-led vaccination scheme helped thousands of patients overcome hesitancy around Covid-19 jabs, Kingston University London research finds

A community pharmacy-led vaccination scheme in South East London successfully supported over 6,000 patients to overcome initial hesitancy around Covid-19 jabs. The programme, which ran for six months, found that a lack of understanding about the vaccine was the biggest reason for patients' hesitation.

City, University of London researcher detects increase in polarization around climate change on social media

A study published in Nature Climate Change found that climate scepticism is growing rapidly on social media, with sceptic tweets shared 16 times more during COP26 than COP21. This increase is attributed to growing 'right-wing activity' opposing climate action, which may be a backlash against climate activist groups.
