Scientists have developed an app that provides insights on COVID-19 hot spots, and the symptoms users must look out for, an advance that may aid public health officials in their efforts to contain the pandemic.

According to the study, published in the journal Science, the COVID Symptom Tracker app has already seen early usage by more than 2.5 million people in the US and the UK, generating valuable data for physicians, scientists, and public officials.

"The app collects daily information from individuals in the community about whether they feel well, and if not, their specific symptoms, and if they have been tested for COVID-19," said study senior author Andrew T. Chan from the Massachusetts General Hospital (MGH) in the US.

The scientists said it may be useful as a planning tool to inform guidelines around self-isolation, identify regions in need of additional ventilators, expand hospital capacity, and provide real-time data to prepare for future outbreaks.

They said the app was launched in the UK on March 24, and became available in the US on March 29.

Since its launch, the study noted that the app has seen more than 3 million users.

"This work has led to the development of accurate models of COVID-19 infection rates in the absence of sufficient population testing," Chan said.

"For example, the UK government has acted upon these estimates by providing advanced notice to local health authorities about when to expect a surge of cases," he added.

Using results from the app, the scientists are also investigating risk factors for infection, as well as the effects of COVID-19 on patients'' health.

Chan also pointed out that the app does not have any contact tracing function in contrast with software that is being rolled out in collaboration with Apple and Google.

"Our app is designed to be entirely voluntary so that they can share information about how they are feeling in a way that safeguards their privacy," he added.

The scientists are asking individuals, even those who are feeling well, to download the app and participate in this effort to provide information related to COVID-19.

  • 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

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.

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.

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

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.”
