NASA reveals why you’ll lose weight in Sri Lanka
Weight gain is a common complaint of holidaymakers. According to Nasa choosing a different destination could make a difference in how much you weigh.Scientists have recently discovered the reason why travellers to Sri Lanka are lighter, whereas you’ll gain weight in Turkey. It’s not the baklava.
Since the 1960s Nasa has known that gravity does not affect the globe evenly, with ‘anomalies’ in the weight of objects travelling from one location to another.Though those hoping to shed might be disappointed.
A traveller weighing 68kg in New Zealand could lose up to 3g when in the Maldives or Canada’s Hudson Bay, where there are areas of lower relative-gravity. The difference is not massive, around 1/25,000 of your bodyweight, but it’s a start.
What it does tell us is that the makeup of the planet is very different under foot, affecting the weight and gravitational force on the surface.Satellites from Nasa’s GRACE mission (Gravity Recovery and Climate Experiment) have been mapping the differences for years. While ocean measuring stations have suggested there is a difference the use of satellite imaging to measure water density has allowed Nasa to build high definition of gravity.
The lowest gravity on the planet is found at the southern tip of Sri Lanka and parts of the Indian Ocean east of the Maldives. North Canada around the Hudson Bay area is also an area of low gravity.The difference is thought to be down to the thickness of the Earth’s crust and the volume of molten rock and magma, beneath the surface.
“The Canadian anomaly has been known for a long time,” said Dan Britt, director of the Center for Lunar and Asteroid Surface Science. The physicist from the University of Florida told the Daily Mail, it is now thought that the changes came about during the last Ice Age when enormous glaciers pressed down on the Earth’s surface.
He described it like squishing a jam sandwich, the thick ice sheets deformed the crust, pushing the fluid to the edges.
“A couple of miles of ice is heavy enough to depress the crust,” said Britt.
Elsewhere ‘heavy’ spots can be explained by currents in molten rock, or magma, and convection currents in superheated bubbling lava.
The strongest gravity earth is located around Bolivia and the northern Andes, where relative gravity represents around 50 additional milligals. Here you’ll be around 1/19613th heavier than at 1 standard gravity.
Objects are also slightly heavier around the poles and around the fault lines of the Pacific. There is an area of increased weight at the top of New Zealand’s North Island following the Kermadec Trench.
The distribution of gravity is slowly changing as the fluid magma redistributes and continental plates shift. Since the launch of the GRACE and GRACE-FO (follow on) satellites in 2018, Nasa has been mapping the slow change, by measuring surface water.
Measuring “the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents provides an integrated global view of how Earth’s water cycle and energy balance are evolving”, says the Nasa GRACE mission.
Rather than helping weight watchers plan their holidays, there are bigger implications of gravitational anomalies on surface water which compound climate changes.(New Zealand Herald)

All set for Colombo rally against govt.’s tax policies
The Frontline Socialist Party-backed People’s Struggle Movement is set to stage a protest march in Colombo today (03) against what it describes as the growing tax burden on the public and the rising cost of living.
The organisers are due to commence the “Colombo March Against Unjust Taxes” at noon from Campbell Park, Borella. The FSP has also been mobilising support for the protest in Colombo and its suburbs in the run-up to the event.
People’s Struggle Movement National Executive Council member Wasantha Mudalige, speaking at a media briefing in Nugegoda yesterday (02), called on the public to join the protest, saying the movement intended to bring the tax burden faced by ordinary people to the forefront.
Mudalige alleged that successive tax measures had placed an excessive burden on households, particularly through taxes on food and educational items. He also criticised the Government over what he described as the high cost of basic food items and the difficulties faced by parents in meeting their children’s educational expenses.
He accused the Opposition of failing to adequately address the issue, claiming that opposition parties raised such concerns, mainly during election periods.
Mudalige also criticised the Government for what he described as a departure from promises made before the 2024 presidential election regarding taxes on educational equipment.
He questioned the tax burden on food items, citing figures of Rs. 100 per kilogramme on dried sprats, Rs. 310 per kilogramme on chicken and Rs. 11 per egg.
He further alleged that while ordinary people were bearing a heavy tax burden, wealthy groups were receiving tax concessions. He also criticised the Government’s economic programme and its implementation of measures associated with the International Monetary Fund (IMF).
The movement has framed today’s protest as part of a broader campaign over the cost of living and taxation. The People’s Struggle Alliance has separately announced that the Campbell Park demonstration will be the first in a series of public actions, with further protests planned in November.
Mudalige said the movement would continue to take the issue to the streets and urged the public to participate in today’s demonstration.
People’s Struggle Movement National Executive Council member Jayantha Amarasinghe also addressed the press.

Yoshitha R money laundering trial postponed
The Colombo High Court yesterday postponed the trial in the case filed under the Prevention of Money Laundering Act against Yoshitha Rajapaksa, son of former President Mahinda Rajapaksa.
The case was taken up before Colombo High Court Judge Udesh Ranatunga, with Yoshitha Rajapaksa, who is currently out on bail, appearing in court.
The trial was postponed as the President’s Counsel appearing for the defence was indisposed.
The Attorney General has filed the case against Rajapaksa, alleging that he committed an offence under the Prevention of Money Laundering Act by purchasing five plots of land in Dehiwala and Ratmalana, worth more than Rs. 73 million.

Lankan troops test mettle in Russian war games
A contingent of the Sri Lanka Army, comprising 20 officers and 55 other ranks, participated in the combined military exercise ‘Wolverine Path II–2026’, conducted with the Armed Forces of the Russian Federation in Vladivostok, Russia, from September 18 to 25.
According to the Ministry of Defence, the exercise primarily focused on counter-terrorism operations and provided participating troops with training in a challenging combined operational environment.
The exercise included a range of tactical activities, including heli-rappelling, close-quarters battle (CQB), ambush operations, sniper firing, drone operations, buggy training and combat medical support.
The Ministry said the training enabled Sri Lankan troops to further develop their combat skills, tactical coordination and operational readiness.
It also provided an opportunity for the two militaries to exchange professional knowledge, operational experience and tactical expertise. Sri Lankan personnel gained exposure to training methodologies, tactical approaches and operational practices adopted by the Russian Armed Forces, the Ministry said.
The participation also enabled the Sri Lankan contingent to identify lessons from the joint training and share its own experiences with the Russian military.
The Sri Lankan contingent returned to the country following the exercise and arrived at Mattala Rajapaksa International Airport on September 28.
The Ministry said participation in the exercise contributed to enhancing the professional knowledge, tactical awareness and operational preparedness of Army personnel while promoting military-to-military cooperation, mutual understanding and professional relations between Sri Lanka and Russia.
