Polycystic ovary syndrome (PCOS), an infertility disorder affecting at least 15% of reproductive-age women, may have at least two different subtypes, suggests a study funded by the National Institutes of Health.

Some common strains of influenza have the potential to mutate to evade broad-acting antibodies that could be elicited by a universal flu vaccine, according to a new study.

Bubble-like structures, made with just protein and RNA, could potentially be engineered to deliver drugs, researchers say.

A new precision drug targeting cancer’s ability to repair its DNA has shown promising results in a clinical trial. The study, designed to test the drug’s safety, found that half of the participants given the new drug either alone or with platinum chemotherapy saw their cancer stop growing, and two participants saw their tumors shrink or disappear completely.

Natural gas that contains larger amounts of hydrogen sulfide and carbon dioxide is termed sour gas. Before it can enter a pipeline, it must be "sweetened" by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produce tailored polyimide membranes that can purify sour gas with a wide range of compositions.

A major Phase 3 trial of capivasertib, a cancer drug has begun. The trial will enrol ~830 patients across 20 countries and will examine the effects of the drug in premenopausal or postmenopausal women, and men, with an advanced form of oestrogen receptor-positive, human epidermal growth factor receptor 2 negative breast cancer.

By studying an individual with a rare brain anomaly that prevents him from seeing certain numbers, researchers have provided new evidence that a robust brain response to something like a face or a word does not mean a person is aware of what they are seeing.

As concern grows among environmentalists and consumers about micro- and nanoplastics in the oceans and in seafood, scientist provide direct evidence of nanoplastic accumulation in terrestrial plants too.

A new study has suggested that, in humans, a special time-locked encoding mechanism might have evolved for speech.

Researchers have proposed four criteria that could allow scientists to understand and empirically investigate whether animals have beliefs.
