When plants face abiotic stresses such as drought, salinity or heat, specific epigenetic marks appear at stress-response genes. Later, these marks help plants mount faster with a stronger defense system.

Although the majority of HPV-related cancers develop in mucosal tissues like the throat or cervix, the rare case of a 34-year-old woman with recurrent cutaneous squamous-cell carcinoma implies that some skin-based HPV types may also directly cause cancer in people with weakened immune systems

If acceptance of a manuscript by a journal is a time for celebration for scientists, so is the acceptance of a cover image for artists. Four journal cover images in five years is a huge achievement for anyone, more so as Suhani is just 14 years old and is in class 9

The loss of the Inseparable gene leads to premature differentiation of neural stem cells into neurons and cytokinesis failure. These cells attempt to divide but fail to maintain internal order. As a result, these defects leave the developing brain depleted of healthy progenitors, resulting in an abnormally small brain — microcephaly

Adolescents who used social media the least had the highest cognitive scores, while those who used it the most had the lowest. Increased social media use was associated with poorer performance in memory, language-related tasks, and lower overall cognitive composite score. The differences, though measurable, were not large

Starch, which has a high glycaemic index upon cooking, can undergo recrystallisation and turn into resistant starch upon cooling, resulting

While ARDS patients with cough and respiratory distress are very likely to expel Nipah virus into the air, there is no hard evidence to suggest that patients generate virus-laden aerosols that can “travel greater distances and remain suspended in the air for extended periods” and infect others

The Bharat Forecast System has demonstrated significant improvement in the rainfall forecast over the core monsoon region, and 30% better accuracy for the extreme rainfall forecast compared with the previous operational model. It has been developed primarily for improving the short- and medium-range weather prediction but may be applied for other scales of prediction as well

Knowing our genetic risks means rewriting what was once seen as destiny. From uncertainty, we are moving toward awareness and prevention, and turning generations of loss into a future of hope

A systematic review and meta-analysis found that women with metabolic syndrome are at an increased risk of gynaecological cancers, regardless of the study design, type of gynaecological cancers, and definition of metabolic syndrome

Cough syrups containing a mixture of antitussives, antihistamines, decongestants and expectorants may appear logical — one drug to dry secretions, another to suppress cough, a third to open nasal passages. But the underlying flaw is that these ingredients often work in opposing ways or have overlapping side effects

As long as protecting the reputation and interests of the Indian pharmaceutical industry is the top priority, it is unlikely that there will be any meaningful reforms to prevent future tragedies caused by DEG. The bid to cover up, distract and obfuscate, as seen in the last few days, serves as valuable pointers

A recent study has shown that a simple blood test can detect traces of cancer more than three years before it is clinically diagnosed. This is more than early detection. But screening tests will need to be 50 times more sensitive to reliably detect cancer this early
