World loses giant tortoise species with death of Lonesome George

Paris, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.

The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.

A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.

The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.

The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.

However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.

Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".

"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."

Washington, Jun 30: Indian-American Medha Raj has been named by Democratic presidential candidate Joe Biden as his digital chief of staff, a key role in his election campaigns which are entirely going virtual due to the Covid-19 pandemic in the US.

In this capacity, Raj will work across all facets of the digital department to streamline and coordinate how to maximise the impact of its digital outputs, the Biden campaign said.

“Excited to share that I've joined Joe Biden's campaign as the Digital Chief of Staff. 130 days to the election and we're not going to waste a minute!” she said on LinkedIn.

Raj comes from Pete Buttigieg's campaign, who has now endorsed Biden.

The news was first reported by CNN, which the news channel said is part of the efforts of the Biden campaign to adapt to an almost entirely virtual campaign trail brought on by the coronavirus pandemic.

The US is the hardest-hit country by the coronavirus pandemic, with more than 2.64 million official cases and over 128,000 deaths.

According to CNN, Clarke Humphrey, who previously worked on Hillary Clinton's 2016 campaign, will act as the Biden campaign's new deputy digital director for the grassroots fundraising.

Jose Nunez is the campaign's new digital organising director.

He is from the Kamala Harris' campaign. Christian Tom is the new director of digital partnerships. Over the past few months, Biden has been relying more and more on digital campaigning and raising funds virtually.

A graduate in international politics from Georgetown University, Raj has earned her MBA from Stanford University.

Biden, 77, is challenging the 74-year-old Republican incumbent President Donald Trump in the November 3 presidential elections.

Former US vice president Biden would formally accept his Democratic presidential nomination at the party’s scaled back convention in Wisconsin’s Milwaukee city on August 20.

In view of the coronavirus pandemic, the Democratic National Convention Committee (DNCC) on Wednesday announced its convention plan to broadcast from Milwaukee and across the nation to reach out to all Americans.

According to some of the latest opinion polls, Biden is leading by more than eight percentage points over Trump.

More than one in six youths were jobless since the onset of the COVID-19 pandemic while those who remain employed have seen their working hours cut by 23 per cent, according to a report by the International Labour Organisation (ILO).

According to the 'ILO Monitor: COVID-19 and the world of work: 4th edition' published on Wednesday, youths are being disproportionately affected by the pandemic, and the substantial and rapid increase in youth unemployment seen since February is affecting young women more than young men, reports Xinhua news agency.

The pandemic is inflicting a triple shock on young people.

Not only is it destroying their employment, but it is also disrupting education and training, and placing major obstacles in the way of those seeking to enter the labour market or to move between jobs, said the report.

At 13.6 per cent, the youth unemployment rate in 2019 was already higher than any other group.

There were around 267 million young people not in employment, education or training worldwide.

"If we do not take significant and immediate action to improve their situation, the legacy of the virus could be with us for decades," said ILO Director-General Guy Ryder.

"If their talent and energy is sidelined by a lack of opportunity or skills, it will damage all our futures and make it much more difficult to re-build a better, post-COVID economy."

The report called for urgent, large-scale and targeted policy responses to support youth, including broad-based employment/training guarantee programs in developed countries, and employment-intensive programs and guarantees in low- and middle-income economies.
