The Royal Swedish Academy of Sciences Tuesday announced the Nobel prize in physics goes to three scientists for their work in helping to understand complex physical systems, work that has proved valuable in quantifying and predicting climate.

At a Stockholm news conference, the academy’s Secretary General Goran K. Hansson and a panel of Nobel jurors presented one half of the physics prize to Syukuro Manabe and Klaus Hasselmann “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming.”

Hansson said the other half of the prize has been awarded to Giorgio Parisi “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales."

The panel said the work of Manabe and Hasselmann “laid the foundation of our knowledge of the Earth’s climate and how humanity influences it.”

Born in Japan and now a senior meteorologist at Princeton University, Manabe pioneered studies in how increased levels of carbon dioxide in the atmosphere lead to increased temperatures at the surface of the Earth.

A professor of meteorology at Max Planck Institute for Meteorology, in Hamburg, Germany, Hasselmann created a model that links together weather and climate, thus answering the question of why climate models can be reliable despite weather being changeable and chaotic.

And Sapienza University of Rome physicist Parisi, over the course of his career, discovered hidden patterns in disordered complex materials, making it possible to understand and describe many different and apparently entirely random materials and phenomena in all areas of science and mathematics.

The three scientists will split the $1.1 million cash prize. The Nobel Prize for medicine was awarded Monday, with prizes for chemistry, literature, peace and economics to be awarded later this week and early next week.

Researchers in Australia have shown a bacteria can sterilize and eradicate a disease-carrying mosquito that is responsible for spreading dengue, yellow fever and Zika.

Three million male Aedes aegypti, or yellow fever mosquitoes, were released in the trial at three sites in Northern Queensland state. They were reared at James Cook University in Cairns and sterilized with a naturally-occurring bacteria called Wolbachia.

Researchers say the bacteria appears to have changed part of the male insects’ reproductive biology, so that female mosquitoes that mate with them lay eggs that do not hatch.

The flying insects were released over a 20-week period in 2018. Mosquito numbers subsequently fell by more than 80%. When scientists returned the following year, they found one of the trial areas had almost no mosquitoes.

Nigel Beebe is an associate professor at the University of Queensland and research scientist at the Commonwealth Scientific and Industrial Research Organization, or CSIRO. He hopes the sterilization method will eventually be used in developing countries.

“We wanted to show in a developed country that the technology was robust, we could mass rear mosquitoes. It is not very expensive to mass rear mosquitoes and it is really the separation of the males from the females,” he said.

The Australian team plans to use a similar technique to suppress the virus-spreading Asian Tiger mosquito that has become established in the Torres Strait in northern Australia.

“At the moment we have to use relatively sophisticated technology to do that. But we are now trying to build something that is much more robust and can be used in tropical countries and will be relatively cheap to actually be able separate the males from the females. The mass rearing of the mosquitoes is actually pretty cheap to do. So, I think, absolutely we will have application in developing countries,” saId Beebe.

Researchers elsewhere are looking at ways to use sterile male mosquitos to curb the spread of malaria, but associate professor Beebe has said it was a “complicated” challenge.

More than 40% of people worldwide suffer from mosquito-borne diseases. The Australian team hopes its “environmentally-friendly mosquito control” method will help tackle current and future outbreaks of dengue and other debilitating diseases.

US scientists David Julius and Ardem Patapoutian on Monday won the Nobel Medicine Prize for discoveries on receptors for temperature and touch, the jury said.

"The groundbreaking discoveries... by this year's Nobel Prize laureates have allowed us to understand how heat, cold and mechanical force can initiate the nerve impulses that allow us to perceive and adapt to the world," the Nobel jury said.

"In our daily lives we take these sensations for granted, but how are nerve impulses initiated so that temperature and pressure can be perceived? This question has been solved by this year's Nobel Prize laureates."

Julius, a professor at the University of California in San Francisco and Patapoutian, a professor at Scripps Research in California, will share the Nobel Prize cheque for 10 million Swedish kronor ($1.1 million, one million euros).

Last year, the award went to three virologists for the discovery of the Hepatitis C virus.

While the 2020 award was handed out as the pandemic raged, this is the first time the entire selection process has taken place under the shadow of Covid-19.

Nominations close each year at the end of January, and at that time last year the novel coronavirus was still largely confined to China.

The Nobel season continues on Tuesday with the award for physics and Wednesday with chemistry, followed by the much-anticipated prizes for literature on Thursday and peace on Friday before the economics prize winds things up on Monday, October 11.

Actor William Shatner, best known for his portrayal of space explorer Captain James T. Kirk in the “Star Trek” television series, announced he will travel to space later this month.

Shatner, 90, will blast off October 12 aboard a Blue Origin rocket. Blue Origin is the space travel company of Amazon founder Jeff Bezos.

If successful, Shatner would be the oldest person ever to travel to space. He will be joined by three other passengers on Blue Origin’s second space venture.

Bezos was among the first Blue Origin passengers in July.

The flight is expected to last about 10 minutes and reach an altitude of 106 kilometers.

"I've heard about space for a long time now. I'm taking the opportunity to see it for myself. What a miracle," Shatner said in a statement.

In a tweet, the actor wrote, “So now I can say something. Yes, it’s true; I’m going to be a ‘rocket man!’ a referral to his spoken-word cover version of singer-songwriter Elton John’s famous song.

“The pandemic has destabilized societies, economies, and governments. It has shown that there is no global security without global health security,” World Health Organization Director-General Tedros Adhanom Ghebreyesus said in a recent address to ambassadors and representatives to the European Union’s political and security committee.

“The fastest and best way to end this pandemic is with genuine global cooperation on vaccine supply and access,” Tedros said. “The longer vaccine inequity persists, the longer the social and economic turmoil will continue, and the more opportunity the virus has to circulate and change into more dangerous variants. We need a global realization that no country can vaccinate its way out of this pandemic in isolation from the rest of the world.”

The Johns Hopkins Coronavirus Resource Center reported Sunday it had recorded 234.6 million global COVID infections and nearly 5 million deaths.

Thousands marched Saturday in Bucharest, Romania, to protest restrictions that begin Sunday to combat a jump in coronavirus infections.

The European nation of 19 million is seeing a shocking rise in the daily number of coronavirus cases. A month ago, the number was about 1,000 new cases a day. On Saturday, Romania reported more than 12,500 new cases, its highest number since the pandemic began in March of last year.

Protesters, mostly maskless, gathered outside government offices, shouting "Freedom, freedom without certificates," and "Down with the government," according to Reuters. One sign read: "Green certificates = dictatorship," The Associated Press reported.

The demonstration was organized by Romania's far-right AUR party, the AP said.

The rising cases have strained the nation’s hospitals — intensive care beds are nearly full — and the protests angered some medical workers.

"The situation in hospitals is serious," Beatrice Mahler, hospital manager of Bucharest's Marius Nasta Institute of Pneumology, told The Associated Press. "We have patients hospitalized in beds in the hallway — all with extremely severe forms of COVID-19."

The restrictions scheduled to take effect Sunday include requiring masks be worn in public, and that shops close at 10 p.m. local time.

Public spaces such as restaurants, theaters and gyms, can remain open — some at only partial capacity — for customers who have COVID-19 passes, meaning they are fully vaccinated, or show proof they have had the illness caused by the coronavirus.

Romania has one of the lowest vaccination rates in the European Union, 33.5% of all adults are fully vaccinated, second only to Bulgaria.

There is a weekend curfew in effect for unvaccinated Romanians, and there are plans to make vaccinations mandatory for health care workers, Reuters said.

Since the pandemic began, Romania has recorded nearly 1.25 million cases of COVID-19 and more than 37,000 people have died, according to Johns Hopkins Coronavirus Resource Center.

Russia’s vaccine

Russia’s health minister, Mikhail Murashko, said Saturday that just some paperwork needs to be finished before its Sputnik V vaccine can be registered with the World Health Organization.

The shot has been approved in more than 70 countries and is used widely in Russia. If it wins approval from the WHO and the European Medicines Agency, that could make it available to other markets, Reuters said.

The WHO could not be immediately reached for comment, Reuters added.

Nicaragua shots

Nicaragua has OK’d two Cuban-made vaccines for use in the Central American nation, the Cuban manufacturer, BioCubaFarma, said Saturday.

Cuba developed three coronavirus vaccines, all of which are awaiting official recognition by the WHO, Reuters reported. Nicaragua authorized Abdala and Soberana for emergency use.

Iran, Vietnam and Venezuela have also OK’d the Cuban vaccines for emergency use in their countries.

A British company says it has developed an easy-to-administer, saliva-based test that can detect whether a person is infectious enough to pass along the coronavirus that causes COVID-19.

The company, Vatic, said in a statement that its test is “extremely accurate” and has not returned a single false positive result in its test group. “This is so important for getting life back to normal,” the company said.

Vatic said its “mission was to design a test that people won’t mind using multiple times a week.”

Tests results are available in 15 minutes, the company said.

The test is not available to the public yet as it undergoes more trials but Vatic is seeking approval for its sale directly to the public.

A report in The Economist says COVID in 2020 has brought an abrupt halt to the steady rise of the rate of lIfe expectancy.

Impact on life expectancy

Researchers in Britain, Denmark and Germany said that between 2019 and 2020 life expectancy dropped in all but two of the 28 countries surveyed.

Life expectancy rose in Denmark and Norway and for women in Finland. Meanwhile, male life expectancy fell by more than a year in Italy, Poland and Spain and fell by more than two years in the United States.

Another report in The Economist says that the death rate from COVID in the U.S. “is about eight times higher in America than in the rest of the rich world” due to vaccine hesitancy and other factors.

The report said, “America’s antipathy to vaccines and continued resistance to other interventions, particularly among Republicans, is worrying. YouGov’s poll indicates that, among those who voted for [former U.S. President] Donald Trump in 2020, 31% say they will not get vaccinated, 71% strongly disapprove of President Joe Biden’s vaccine mandate and nearly 40% never wear a face mask. That remains a deadly combination.”

“The pandemic has destabilized societies, economies, and governments. It has shown that there is no global security without global health security,” World Health Organization Director-General Tedros Adhanom Ghebreyesus said about COVID-19 in a recent address to ambassadors and representatives to the European Union’s political and security committee.
