Exercise can rejuvenate brain, delay cognitive decline: Study

Published

on

New Delhi, May 15 (IANS) Physical activity has a significant effect on brain health, and it can not only rejuvenate your brain but also prevent or delay cognitive decline that comes with ageing, according to a new study on Wednesday.

A team from the University of Queensland in Australia focussed on the expression of genes in individual cells in the brains of mice.

The results, published in the journal Aging Cell, showed that exercise has a significant impact on gene expression in microglia — the immune cells of the central nervous system that support brain function.

Importantly, the team found that exercise reverts the gene expression patterns of aged microglia to those seen in young mice.

“We were both surprised and excited about the extent to which physical activity rejuvenates and transforms the composition of immune cells within the brain, in particular the way in which it was able to reverse the negative impacts of ageing,” said Jana Vukovic, from the University of Queensland.

Vukovic noted that the study stresses the importance of “tailored exercise programmes”.

“Our findings should help different industries to design interventions for elderly individuals who are looking to maintain or improve both their physical and mental capabilities,” she said.

Further, the study showed that running on a wheel “prevented and/or reduced the presence of T cells in the hippocampus” in mice during ageing.

T-cells are immune cells known to increase with age. They found that microglia cells are required for the stimulatory effects of exercise to help form new neurons in the brain’s hippocampus — a region involved in memory, learning, and emotion. The study can help design interventions for older adults to maintain or improve both physical and mental health.

We can become 'Viksit Bharat' even before 2047 with robust startup ecosystem: Hardeep Puri

Published

New Delhi, May 20 (IANS) Riding on the overall economic growth across the spectrum, especially in the vibrant startup and unicorn ecosystem, India can achieve the ‘Viksit Bharat’ status even before 2047, Union Minister Hardeep Singh Puri said on Monday.

Addressing startup/unicorn founders and innovators during the ‘Digital Bharat, Viksit Bharat’ event in the national capital, the Union Minister said that India is the only economy that is growing, even at the most conservative estimate, at over 7 per cent, to become the fourth and then the third-largest world economy sooner than expected.

“This will happen only because of the quality of the transformation which has been facilitated by Prime Minister Narendra Modi’s government and its conducive policies,” he told the gathering.

Startups emerging from small cities, from less-privileged backgrounds, were not even conceivable 10 years ago, he noted.

“During the previous regimes, the only criteria required to become successful was connections. This is no more the case as innovation is now happening in small towns and cities,” Hardeep Singh Puri said.

India is now home to more than 100 unicorns (with a valuation of $1 billion and above) and over 1.25 lakh startups.

“India is third in the number of unicorns and second in total number of startups and the first nation in creating new startups,” the Union Minister said.

No one will lecture India about 'WTO norms' anymore: Zoho's Vembu

Published

By

New Delhi, May 20 (IANS) Zoho Founder and CEO Sridhar Vembu on Monday said that no country will lecture India about World Trade Organisation’s (WTO) norms anymore after the US imposed hefty tariffs on Chinese electric vehicles (EVs).

In March, China started dispute settlement proceedings against the US at the WTO, accusing Washington of “discriminatory” EV subsidies.

Last week, US President Joe Biden unveiled plans to quadruple tariffs on Chinese EVs.

“The US has imposed big new tariffs on Chinese EVs. Trade frictions, particularly between the US and China, are escalating rapidly,” Vembu posted on social media platform X.

“At least, no one will lecture India about “WTO norms” anymore. More seriously, this is the inevitable outcome of decades of extreme monetary madness, which gave rise to exploding trade deficits and debt,” he elaborated.

The Biden move plans to hike tariffs this year on Chinese EVs from 25 per cent to 100 per cent and on lithium-ion EV batteries from 7.5 per cent to 25 per cent.

“Conventional wisdom has been that ‘deficits don’t matter.’ We don’t have to balance any book, we can let trade imbalances go on forever. It is this flawed idea that is undermining global trade now,” said Vembu.

The Biden administration also plans to hike tariffs on solar cells from 25 per cent to 50 per cent, on certain steel and aluminum products from up to 7.5 per cent to 25 per cent.

By

New Delhi, May 20 (IANS) As organisations continue to spend billions of dollars on cybersecurity each year to prevent their businesses from losing sensitive data and important figures, a new report on Monday revealed that the global cybercrime cost has increased 12 times faster than total cybersecurity spending in the past six years.

According to data presented by Stocklytics.com, the total cybersecurity spending has grown by 78 per cent since 2018 and the cybercrime cost soared by 972 per cent in this period.

In 2018, companies and organisations globally spent $102.7 billion on cybersecurity measures. Two years later, this figure increased to more than $150 billion.

As per Statista, the annual spending on cybersecurity solutions and services is to hit $183 billion this year, or 78 per cent more than the figure reported six years back.

Cyber attacks, including ransomware, data breaches, cyber espionage, and phishing, will inflict damages totalling $9.2 trillion in 2024, $1.1 trillion more than last year and a shocking 972 per cent more than six years ago.

“This cost includes stolen money, damage and destruction of data, lost productivity, theft of intellectual property, theft of personal or financial data, post-attack disruption to the ordinary course of business, restoration and deletion of hacked data and systems, and reputational harm,” the report mentioned.

Moreover, the report said that global cybersecurity spending is expected to hit $200 billion in 2025 — 50 times less than the annual cybercrime cost.

By 2028, cybercrime will cost businesses a shocking $13.8 trillion, or 49 per cent more than this year, the report noted.

TRAI move on new broadcasting policy to make India a global content hub: BIF

Published

on

By

New Delhi, May 20 (IANS) Broadband India Forum (BIF) on Monday commended the initiative by the Telecom Regulatory Authority of India (TRAI) to gather public input for the National Broadcasting Policy (NBP).

The BIF said an enabling policy framework can provide the much-needed fillip for the broadcasting sector to unlock its full potential and position India as a global leader in broadcasting.

“Coming on the footsteps of the recently announced Indian Telecommunications Act 2023, the proposed National Broadcast Policy could serve as a great enabler of reforms in the broadcasting sector and likely to give a big boost to the entire media and entertainment sector while making India a global content hub,” said T. V. Ramachandran, President of BIF.

In its submission, BIF has addressed four key areas, including bridging the viewership gap, tariff forbearance, OTTs are not broadcasting services and market-driven innovation for choice of direct-to-mobile (D2M) technology.

“Private DTH operators should be empowered to introduce innovative services akin to DD Free Dish to increase television penetration in rural and remote areas where Pay TV services might not be prevalent,” said the forum.

It also advocated the need for permitting tariff forbearance like for telecom (where effectively only three operators available) so that private operators can optimise customer benefits and marketing strategies.

BIF stated that OTTs and broadcasting services are distinct from each other.

OTT is a sunrise sector with growth potential and is already contributing immensely to the growth of India’s digital economy.

According to a recent study by BIF, the economic value of the app economy estimated at the current rate of growth is expected to reach up to 12 per cent of India’s economy by 2030.

“Traditionally, OTT services have not been a part of the broadcasting ecosystem since they are functionally distinct from TV and radio broadcasting that involves a combination of carriage and content,” according to the submission by the BIF.
