CHILDREN from lower-income backgrounds, where mothers also had a low level of education, have weaker brain activity, a survey conducted in India showed.

A team from the University of East Anglia (UEA) studied the brain function of children aged between four months and four years in rural India.

The results were compared with children from families in midwest America.

Researchers found that children in India from families with low maternal education and income showed weaker brain activity and poorer distractor suppression in the left frontal cortex area, a major section of the brain  involved in controlling language related movement.

Using a portable ‘functional near infrared spectroscopy’ (fNIRS) device, the researchers measured the brain activity of 42 children.

They investigated the children’s ‘visual working memory’ or how well they are able to store visual information and detect changes in the visual environment when they occur.

The children took part in a visual test involving blinking displays of coloured squares.

The goal of the test was to see if children could remember the colours well enough to detect that there was always a colour change on one side of the display, while the colours on the other side always stayed the same.

Lead researcher Prof John Spencer, from UEA’s School of Psychology said: “We use our visual working memory around 10,000 times a day. Children begin to develop this skill in early infancy and it gradually improves through childhood and adolescence. We know that it is an excellent marker of  early cognitive development.”

Factors such as parental education, income, caste, religion, the number children in the family, and economic status were taken into account.

The team, which included researchers from the University of Stirling, carried out their study in most populous northern Indian state of  Uttar Pradesh (UP).

“Each year, 250 million children in low and middle income countries fail to reach their developmental potential,” Professor Spencer said.

“There is therefore a growing need to understand the global impact of poverty on early brain and behavioural development.”

The study was conducted in partnership with the Community Empowerment Lab based in the capital city of Uttar Pradesh, Lucknow.

New Covid strain Stratus spreads in UK with unusual hoarse voice symptom

Key points

  • A new Covid strain known as Stratus is spreading across the UK
  • The variant is marked by a distinctive symptom: a hoarse or raspy voice
  • Sub-variants XFG and XFG.3 now account for 30% of cases in England
  • Experts say there is no evidence of more severe disease
  • Lower immunity levels may make more people vulnerable to infection

Covid variant Stratus on the rise in the UK

A new strain of Covid-19, known as Stratus, is spreading across the UK and drawing attention for its unusual symptom — a hoarse or raspy voice. According to data from the UK Health Security Agency (UKHSA), Stratus and its two sub-variants, XFG and XFG.3, are responsible for around 30 per cent of Covid cases in England.

Of the two, XFG.3 is currently the more dominant. The UKHSA confirmed that monitoring of all circulating Covid-19 variants is ongoing as part of regular surveillance.

Neurogenesis, the process by which new neurons form in the brain

Human brain continues forming neurons well into old age, study finds

Key points

  • New neurons continue forming in the brain’s hippocampus into old age
  • Study confirms presence of neural progenitor cells in adults
  • DNA carbon dating and single-nucleus RNA sequencing were used
  • Research shows variation in neuron production between individuals
  • Findings could aid treatments for neurodegenerative and psychiatric disorders

Human brain shows ongoing neuron formation into older age

A new study has confirmed that the human brain continues to produce new nerve cells well into late adulthood, challenging previous assumptions about age-related decline in neurogenesis. The findings, published in the journal Science, provide fresh insight into how adaptable the brain remains over a lifetime.

Neurogenesis, the process by which new neurons form in the brain, is known to occur in the hippocampus — a region involved in memory. While previous research has suggested that this process continues throughout life, there has been limited concrete evidence of the presence of neural progenitor cells in the adult brain.

Kent County Show opens with royal visit

The Kent County Show returned to Detling near Maidstone on Friday, marking the start of a major three-day celebration of farming, food, and rural living. The event opened with a special visit from the Duchess of Edinburgh, who is attending for the first time in 16 years.

Sophie, Duchess of Edinburgh, who grew up in Brenchley near Tunbridge Wells and serves as patron of the Association of Show and Agricultural Organisations (ASAO), met with farmers, equine exhibitors, and local businesses on her tour of the showground.

Sri Aurobindo

Heehs’s biography is grounded in extensive archival research across France, England, India and Israel

Sri Aurobindo and the rise of the Asian century

Dinesh Sharma

My friend and colleague, the American historian Peter Heehs, who has lived in Pondicherry, India, for decades, recently published a compelling new biography, The Mother: A Life of Sri Aurobindo’s Collaborator (2025). Heehs previously authored The Lives of Sri Aurobindo (2008), which remains one of the most balanced and scholarly accounts of Aurobindo’s life.

According to Heehs, most previous biographies of the Mother were written for devotees and relied on secondary sources, often presenting her as a divine incarnation without critical engagement. “Such biographies are fine for those who see the Mother as a divine being,” Heehs said, “but they can be off-putting for readers who simply want to understand her life – as an artist, writer, spiritual teacher, and founder of the Ashram and Auroville.”

Black women cancer risk

Study warns of rising uterine cancer rates, with Black women hardest hit

Key points

  • Uterine cancer cases and deaths are projected to rise significantly in the US by 2050.
  • Black women are expected to experience the highest increase in incidence-based mortality.
  • A new model predicts incidence rising to 86.9 cases per 100,000 for Black women and 74.2 for White women.
  • Researchers stress the urgent need for improved prevention and early detection strategies.

Sharp increase in uterine cancer predicted over next three decades

Uterine cancer, currently the fourth most commonly diagnosed cancer among women in the United States, is projected to see a substantial rise in both cases and deaths by 2050, particularly among Black women. A new study led by researchers at Columbia University warns of worsening racial disparities in outcomes if preventative measures are not introduced.

This year alone, around 69,120 new cases of uterine cancer and nearly 14,000 deaths are expected in the United States. However, projections by the Columbia University research team, published in Cancer Epidemiology, Biomarkers & Prevention, indicate a significant increase in both incidence and mortality over the next 30 years.
