‘World’s oldest man’, 113, dies in Japan

New Delhi, May 31: India registered its highest single-day spike of COVID-19 cases on Sunday with 8,380 new infections reported in the last 24 hours, taking the country's tally to 1,82,143, while the death toll rose to 5,164, according to the Union Health Ministry.

The number of active COVID-19 cases stood to 89,995, while 86,983 people have recovered and one patient has migrated, it said.

"Thus, around 47.75 per cent patients have recovered so far," a senior health ministry official said.

The total confirmed cases include foreigners.

The death toll has gone up by 193 since Saturday morning, of which 99 were from Maharashtra, 27 from Gujarat, 18 from Delhi, nine each from Madhya Pradesh and Rajasthan, seven from West Bengal, six each from Tamil Nadu and Telangana, five in Bihar, three from Uttar Pradesh, two from Punjab, and one each from Haryana and Kerala.

New Delhi, Jun 2: Congress leader Rahul Gandhi on Monday took a jibe at Prime Minister Narendra Modi over Moody's Investors Service downgrading India's sovereign rating to the lowest investment rate and said that the global rating agency has rated his handling of the country's economy "a step above junk".

"Moody's has rated Modi's handling of India's economy a step above JUNK. Lack of support to the poor and the MSME sector means the worst is yet to come," the Congress leader tweeted citing a media report on Moody's downgrading the nation.

On Monday, Moody's downgraded the country's rating to "Baa3" from "Baa2". This comes at a time when the government is facing criticism from the Opposition over its handling of the COVID-19 situation and measures to boost the economy.

The government has already announced a stimulus package of Rs 20 lakh crore to deal with the situation.

Paris, Jul 2: Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Universite).

The scientists analysed the star's motion and concluded that it hosted two planets, WASP-148b and WASP-148c. The observations showed that the two planets were strongly interacting, which was confirmed from other data.

Whereas the first planet, WASP-148b, orbits its star in nearly nine days, the second one, WASP-148c, takes four times longer. This ratio between the orbital periods implies that the WASP-148 system is close to resonance, meaning that there is enhanced gravitational interaction between the two planets. And it turns out that the astronomers did indeed detect variations in the orbital periods of the planets.

While a single planet, uninfluenced by a second one, would move with a constant period, WASP-148b and WASP-148c undergo acceleration and deceleration that provides evidence of their interaction.

The study will shortly be published in the journal Astronomy & Astrophysics.
