Three scientists receive Noble Prize for Chemistry

American scientists Frances Arnold and George Smith and British researcher Gregory Winter have won the Nobel Chemistry Prize for harnessing the principles of evolution to develop proteins used to make everything from bio-fuels to pharmaceuticals, the jury said.

Arnold won one half of the nine million Swedish kronor (about $1.01 million or 870,000 euros) prize, while Smith and Winter shared the other half.

According to CNN, the Royal Swedish Academy, while announcing the awards said that this year’s prize “awards a revolution based on evolution,” and goes to scientists who “applied the principles of Darwin in the test tube.”

Arnold, of the California Institute of Technology, was recognized for performing the first-ever “directed evolution” of enzymes, which are proteins that catalyze chemical reactions. Enzymes produced through directed evolution are used to manufacture everything from sustainable bio-fuels to pharmaceuticals.

The American scientist becomes only the fifth woman to have ever won the prize, following Ada Yonath in 2009, Dorothy Crowfoot Hodgkin in 1964, Irène Joliot-Curie in 1935, and her mother, Marie Curie, in 1911.

Smith, a professor at the University of Missouri, won for a method known as “phage display,” which uses bacteriophage — a virus that infects bacteria — to evolve new proteins.

Washington Sundar’s inclusion in the fourth Test: Will he make a significant impact for India?

Published

Washington Sundar

Washington Sundar has been thrust into the spotlight once again as he made his return to India’s playing XI for the fourth Test against Australia at the Melbourne Cricket Ground. His inclusion, which came at the expense of Shubman Gill, has sparked a flurry of discussions, both on social media and among cricket experts, about his role in the team, his credentials as an all-rounder, and what his performance will mean for India’s chances in the ongoing Border-Gavaskar Trophy.

Sundar, who has previously impressed with his all-round abilities, has had a tumultuous journey with the Indian cricket team, especially in the Test format. Known for his ability to bowl tight off-spin and contribute with the bat, Sundar’s most memorable performance came in India’s historic win over Australia in the 2020-21 series. However, it is his return to the Test squad for this high-profile series that has gotten the cricket world talking.

His inclusion comes in the wake of Ravichandran Ashwin’s retirement from limited-overs cricket and his exclusion from the playing XI in the first few Tests of the series. With Ashwin’s absence, Sundar was given an opportunity to step into the spin department alongside Ravindra Jadeja, especially after a stellar performance against New Zealand earlier this year. Sundar claimed seven wickets in a single innings during that match, putting in a performance that elevated his reputation as a reliable bowling option. This made his re-entry into the squad even more anticipated, with many hoping for him to make an immediate impact.

However, while Sundar’s return has been welcomed by many, not all are convinced about his role as an all-rounder in the traditional sense. Former cricketer Sanjay Manjrekar, known for his insightful commentary, expressed his doubts over Sundar’s credentials as an all-rounder, suggesting that the young player’s contributions with the bat and ball have not always been consistent enough to fulfill the high expectations that come with such a role. Manjrekar also included Nitish Reddy in his criticism, questioning whether both players could truly fulfill the versatile role needed in modern Test cricket.

For Sundar, however, his performance will likely speak louder than any criticism. The pressure on him to perform in a Test series as crucial as this one against Australia is immense, and many eyes will be on him to prove his worth. With the likes of Marnus Labuschagne, Usman Khawaja, and Steve Smith in Australia’s formidable lineup, Sundar’s ability to deliver with the ball could be pivotal in the context of the game.

Despite the debate, Sundar’s skills as a bowler have been widely recognized. His calm demeanor and knack for bowling tight lines have helped him earn the confidence of the Indian team management. What sets him apart is his maturity at a young age, especially in pressure situations. Though his batting has not always been as consistent as his bowling, his ability to contribute with the bat adds another dimension to his utility in the team.

The 24-year-old has made his way through the ranks, and this series offers him another chance to prove his mettle. His role in the ongoing series could prove vital, particularly in India’s bid to retain the Border-Gavaskar Trophy. If Sundar can deliver with both bat and ball, he could become a regular feature in the Indian Test team, solidifying his position as a key all-rounder in the squad.

With the series tied and both teams fighting hard for supremacy, Sundar’s performance could be a game-changer for India. His return is symbolic not just of the changes in the Indian squad but of the continued shift towards integrating youth and fresh talent into the team. As the series progresses, all eyes will be on Sundar, who now faces the challenge of turning potential into performance and answering the critics who have questioned his place in the Test team.

Day 1 of the fourth Test between India and Australia at the iconic Melbourne Cricket Ground saw Australia end the day at 311/6, holding a slight advantage despite a spirited Indian fightback led by Jasprit Bumrah.

Steve Smith, steady as ever, remained unbeaten on 68, joined by Pat Cummins (8*) at the crease. The day belonged to Australia’s batting lineup, which delivered a solid performance on a favorable pitch.

Debutant Sam Konstas was the highlight of the Australian innings, crafting an impressive 60 runs in his first Test appearance. The 19-year-old showcased maturity beyond his years, dispatching the Indian bowlers with confidence. His knock complemented the contributions from Usman Khawaja (57) and Marnus Labuschagne (72), who anchored Australia’s innings with composed fifties.

India’s bowling unit, spearheaded by the ever-reliable Jasprit Bumrah, kept the visitors in the contest. Bumrah’s figures of 3/75 reflected his knack for breaking partnerships at crucial moments. Supporting him, Ravindra Jadeja, Washington Sundar, and Akash Deep each claimed a wicket to prevent Australia from running away with the game.

Australia’s playing XI featured a formidable lineup, including skipper Pat Cummins, Mitchell Starc, and spinner Nathan Lyon. India fielded an interesting combination, with Rohit Sharma leading a side that featured young talents like Yashasvi Jaiswal and Nitish Kumar Reddy alongside experienced campaigners Virat Kohli and Rishabh Pant.

As Day 1 concluded, the match remained finely poised. While Australia’s top order laid a strong foundation, India’s bowling ensured they stayed in contention, setting the stage for an intriguing Day 2 of the Boxing Day Test in the Border-Gavaskar Trophy 2024/25.

The stakes remain high as both teams seek to assert dominance in this crucial encounter.

Putin deliberately chose Christmas to attack, says Zelensky as Russia targets Ukrainian energy infrastructure

The Ukrainian Air Force stated that multiple missiles had been launched at the Kharkiv, Dnipro, and Poltava regions in the east.

Russian President Vladimir Putin chose Christmas Day deliberately to launch a brutal assault on Ukraine’s energy infrastructure, resulting in widespread explosions throughout the country, said Ukrainian President Volodymyr Zelensky on Wednesday.

The attack involved a significant barrage of missiles and drones aimed at critical energy facilities, including a thermal power plant, prompting citizens to seek refuge in metro stations on Christmas morning.

“Today, Putin intentionally chose Christmas for this attack. What could be more inhumane?” Zelensky remarked, asserting that Russia is resolutely pursuing a strategy to cause blackouts across Ukraine.

He emphasised that each large-scale Russian strike necessitates careful preparation, stating, “It is never a spontaneous decision. It is a deliberate choice—not only of targets but also of timing.”

In his statement on X, Zelensky reported that more than 70 missiles, including ballistic types, and over 100 attack drones were launched at Ukraine’s power infrastructure.

Ukrainian Vice Prime Minister Oleksii Kuleba said that at least one person was killed in the Dnipro region due to the attacks. He noted that heating services were disrupted for 155 residential buildings in Ivano-Frankivsk and that around 500,000 residents, or 2,677 buildings, in the Kharkiv region, were left without heat.

Ukrainian Foreign Minister Andrii Sybiha mentioned that one Russian missile had passed through Moldovan and Romanian airspace. He added that Ukraine managed to intercept at least 50 missiles and a considerable number of drones during the attack.

Ukrainian Energy Minister Herman Halushchenko stated that Russia had significantly targeted the country’s energy infrastructure again in a Facebook post. The Ukrainian Air Force stated that multiple missiles had been launched at the Kharkiv, Dnipro, and Poltava regions in the east.

“The electricity distribution system operator is implementing necessary measures to limit consumption in order to reduce the negative impact on the power system,” he explained. “Once the security situation permits, energy workers will assess the damage.”

DTEK, Ukraine’s largest private energy company, reported that a Russian strike hit one of their thermal power plants on the morning of December 25, 2024, marking the 13th attack on Ukraine’s power grid this year. CEO Maxim Timchenko condemned the assault on X, stating, “Denying light and warmth to millions of peace-loving people celebrating Christmas is a depraved and evil act that must be answered.”

In response to the massive missile attack, the Ukrainian state energy operator, Ukrenergo, implemented preemptive power outages nationwide, resulting in electricity shortages in several districts of Kyiv.

In Kharkiv, at least seven strikes ignited fires throughout the city, as reported by regional head Oleh Syniehubov on Telegram. Authorities confirmed at least three injuries. Kharkiv Mayor Ihor Terekhov warned residents, “Kharkiv is under heavy missile fire. A series of explosions have occurred in the city, and ballistic missiles are still incoming. Please stay in safe locations.”
