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)

US$ 2.5 mn cyber heist exposes system failures
COPF final report on USD 2.5 mn cyber fraud recommends action against all responsible
The US$2.5 million loss incurred during Sri Lanka’s foreign debt repayment to Australia was a clear case of a cybercrime and theft, Committee on Public Finance (COPF) Chairman Dr. Harsha de Silva told Parliament yesterday.
Presenting the COPF final report on the cyber fraud, Dr. de Silva said the incident amounted to a serious financial crime and called for a comprehensive investigation, by law enforcement authorities, to identify and prosecute all those responsible.
The report revealed serious governance, procedural and operational failures that enabled the fraudulent transfer of public funds, while recommending sweeping reforms to strengthen cybersecurity, financial controls and public debt management systems.
According to the report, officials of the Treasury and the Central Bank bore responsibility for governance lapses that contributed to the failures. It also highlighted the fact that the Ministry of Finance was operating an outdated Microsoft Exchange Server after security support had ended, while basic safeguards, such as multi-factor authentication, had not been implemented.
The COPF said suspicious payment instructions linked to debt repayments involving India, the United Kingdom, Germany and Belgium had also been detected, preventing further losses. However, the US$ 2.5 million fraud materialised only in the repayment transaction involving Australia.
The report has noted that officials had failed to verify lender email domains, relied on unverified email communications and lacked adequate internal controls, allowing the fraud to continue for months.
Although the investigation uncovered system-wide weaknesses across several institutions, only four mid-level Finance Ministry officials had been suspended so far, the report said.
The COPF has recommended a special audit of the foreign debt repayment process, strengthened cybersecurity measures across state institutions, updated financial regulations and improvements to public debt management systems.

Opposition signs no-confidence motion against Justice Minister for dereliction of duty over Negombo Prison deaths
Opposition Leader Sajith Premadasa, together with Opposition MPs, yesterday signed a No-Confidence Motion (NCM) in Parliament against Justice Minister Harshana Nanayakkara.The move comes in response to the unrest at the Negombo Prison, where both prison officers and inmates were killed.
Opposition members said the Minister had failed to fulfill his responsibility and accountability regarding their safety.According to the Opposition group, the NCM seeks to hold the Minister directly accountable for lapses in ensuring protection within the prison system.

AG informs SC of e-visa agreement review
The Attorney General yesterday informed the Supreme Court that the government has decided to review the legality of agreements entered into by the previous administration to hand over the country’s electronic visa issuance operations to private companies.
Additional Solicitor General Viveka Siriwardena, appearing for the Attorney General, made the submission when the Supreme Court took up the fundamental rights petitions filed by former MPs President’s Counsel M.A. Sumanthiran, Patali Champika Ranawaka, and Rauff Hakeem, challenging the previous Cabinet’s decision to outsource the e-visa system.
The petitions were heard before a three-judge bench, comprising Chief Justice Preethi Padman Surasena and Justices Achala Wengappuli and Arjuna Obeyesekere.
The Additional Solicitor General informed court that the current Cabinet had appointed a subcommittee to examine the legality of the agreements with the private companies and requested time to report on its findings, stating that the review was still underway.
President’s Counsel Sumanthiran, appearing as one of the petitioners, told the court that although the present government had indicated its intention to cancel the transaction, the petitioners wished to proceed with the case.
He noted that members of the current Cabinet had been named as respondents in the petitions.The Supreme Court directed the petitioners to issue notice on the members of the current Cabinet, named as respondents, and fixed September 29 for further proceedings.
