Review examines urinary leakage during sex in women and how it may have different causes

This narrative review describes coital urinary incontinence—urine leakage that happens during sexual activity—in women. It explains why many cases may be underdiagnosed and discusses how leakage at different moments may relate to different underlying mechanisms. Because this is a review, it reflects and synthesizes existing research rather than providing new trial results.

In Nairobi, migrants weigh the label “mzungu” for belonging and privilege

In Nairobi, the Kiswahili term “mzungu” can carry a mix of meanings tied to whiteness, social privilege, and being foreign. Researchers report that migrants and Kenyans negotiate the label—some reject it, others use it with distance or irony—revealing how privilege is lived through everyday words.

Review maps ways to cut wasted eggs and cull less day-old chicks

A new review in Animals examines two major bottlenecks in poultry production: egg quality drops before incubation and the routine culling of male chicks after hatch. It finds that lab tests can be accurate under controlled conditions, but wider use is limited by performance across batches and practical safety and scale issues. The authors propose an end-to-end, connected workflow to help bridge the gap from lab to farms.

New analysis finds combined aerobic and strength training is linked to better outcomes in coronary heart disease

This systematic review and meta-analysis examined whether combined aerobic and resistance training (CART) affects exercise capacity, muscle strength, health-related quality of life, and mortality in people with coronary heart disease (CHD). Compared with non-exercising usual care, the analysis found CART was associated with improvements in several fitness and strength measures and a reduction in mortality. Compared with aerobic-only training and resistance-only training, CART showed additional benefits for some outcomes in pooled results.

In four Asian cities, treating “migrants” as a single box misses how people move and stay

“Migrant” categories in research can be too rigid, the study argues, and may leave people feeling “boxed in.” Using survey data from 2016 and family history interviews in four cities, the researchers test ways to understand how movement—and staying put—relates to upward social mobility.

Antibody treatment lowers worms and gut inflammation in drug‑challenged lambs

A vaccine journal study reports that giving lambs antibodies by mouth against an Haemonchus contortus antigen reduced worm development and egg production after experimental infection. The treated animals also showed lower signs of inflammation in the gut.

Social media use in Baghdad dorms linked to more anxiety, depression and isolation

A study of female university students living in dormitories in Baghdad links social media use to worse mental health, including more anxiety, depression, and social isolation. The researchers report that longer daily use and entertainment or social comparison content were associated with these mental health indicators.

Biodegradable zein-humic material removes chloride and iron in amine gas cleaning

Corrosion-causing chloride and dissolved iron can build up in amine-based gas-sweetening systems, raising maintenance costs. A biodegradable composite made from zein nanoparticles and humic substances removed both impurities from a methyldiethanolamine solution and reduced carbon-steel corrosion in experiments.

Urine-derived fertilizer keeps phosphorus available in tropical soil for maize

A study in *Scientific Reports* tested phosphorus recovered from human urine as a fertilizer in a tropical Oxisol planted with maize. The urine-derived struvite supported substantial shoot growth and left higher residual phosphorus in soil after cultivation, suggesting it released phosphorus in a way that better resisted soil “locking up.”

Green-made nickel-doped zinc oxide stops bacteria and blocks key virulence genes

Nickel-doped zinc oxide nanoparticles were made using an extract from Salvia hispanica. In lab tests, they inhibited bacterial biofilms and reduced the activity of several virulence genes, while also triggering apoptosis and cell-cycle arrest in cancer cells. The researchers also report stronger antibacterial effects against Staphylococcus aureus than against normal cells’ growth.

Earth’s earliest clues and lab chemistry suggest no single place made life

A review of evidence from Earth’s Hadean era and experiments on prebiotic chemistry finds that no single environment on early Earth appears to meet all the conditions needed for life to begin. Instead, the paper argues that multiple, connected processes across different settings likely helped build and stabilize the molecules that later became biology.

Unfolded-protein stress kills insulin cells via JNK and p53 in mice and humans

A study in mice and human cells finds that ER stress linked to unfolded proteins can trigger beta cell death through a pathway involving JNK and p53. Inhibiting JNK in living animals, and inhibiting both JNK and p53 in human cells, improved beta cell survival.

Visibility drives drivers’ pupil changes in tunnel lighting, with a workable compensation model

A new field study measured drivers’ pupil size as vehicles moved through four road tunnels with different shapes and lighting. Visibility emerged as the strongest driver of pupil changes, and the researchers proposed a “visibility-driven compensation” model to match the non-linear link between visibility and pupil response.

AI tool uses emergency triage data to predict suicide risk within 30 days

A study in Scientific Reports tested an AI system that predicts suicide-related behaviour within 30 days of an emergency department visit using structured triage information available at admission. The best-performing model, a LightGBM system, showed AUROC 0.88 and good recall on an independent test set, and highlight likely drivers such as prior psychiatric history, age, and physiological variables.

AI deepfake image detector that weighs its confidence to stay accurate

Researchers report DeepFakeBuster, an AI system for detecting deepfake images that combines multiple detection signals and adjusts their influence using confidence estimates. On a test set of 192,000 authentic and manipulated images, the approach reached 97.8% accuracy under the evaluated conditions.
