India’s Republic Day: A Celebration of Democracy and Duty 🇮🇳

India’s Republic Day, celebrated every year on 26 January, marks one of the most significant milestones in the nation’s history. On this day in 1950, the Constitution of India came into force, transforming the country from a constitutional dominion into a sovereign democratic republic. Republic Day is not merely a national holiday; it is a reminder of India’s collective resolve to govern itself by the ideals of justice, liberty, equality, and fraternity.

The importance of Republic Day lies in the Constitution of India, a living document drafted under the leadership of Dr. B. R. Ambedkar and adopted after years of debate and deliberation. The Constitution provides the framework for governance, safeguards fundamental rights, and defines the duties of citizens. By adopting it, India affirmed that power would rest with its people, exercised through democratic institutions rather than inherited authority.

The hidden timing system that shapes how you think

The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different internal clocks and rely on white matter connections to share information across these timescales. The way this timing is organized affects how efficiently the brain switches between activity patterns tied to behavior. Differences in this system may help explain why people vary in cognitive ability.

The human brain is always at work, handling information that arrives on very different timelines. Some signals demand instant reactions to changes in the environment, while others unfold more slowly as we interpret meaning, context, or intent.

A new study from Rutgers Health, published in Nature Communications, explores how the brain brings these fast and slow signals together. The research focuses on how networks of white matter connections…

Science in 2026: the events to watch for in the coming year

The rise of AI scientists, missions to explore the moons of Earth and Mars and a massive ocean-floor drill are among the developments set to shape research in 2026.

AI for science

Research powered by artificial intelligence made leaps this year, and it is here to stay. AI ‘agents’ that integrate several large language models (LLMs) to carry out complex, multi-step processes are likely to be used more widely, some with little human oversight. The coming year might even bring the first consequential scientific advances made by AI. But heavier use could also expose serious failures in some systems. Researchers have already reported errors that AI agents are prone to, such as the deletion of data.

Next year will also bring techniques that move beyond LLMs, which are expensive to train. Newer approaches focus on designing small-scale AI…

Why ultra-processed foods make teens eat more when they aren’t hungry

A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed diet. Because eating without hunger predicts future weight gain, these findings hint at a heightened vulnerability during late adolescence.

Rates of excess weight are climbing among young people in the United States.

An analysis published in The Lancet predicts that by 2050, about one in three Americans between 15 and 24 years old will meet the criteria for obesity, putting them at higher risk for serious health problems.

Many influences contribute to this trend, including genetics and low levels of physical activity, but diet plays a central role.
