Ukraine pushes east, Moscow vows to win back lost ground

5 Oct 2022 5 Oct 2022

Kyiv on Wednesday claimed further victories over Russian troops in eastern Ukraine as the Kremlin vowed to recapture territory lost in a lightening Ukrainian counteroffensive.

In recent weeks, Ukraine’s forces, bolstered by Western weapons, have wrested Russian troops out of a string of towns and villages in the east and in the south.

Kyiv this week claimed gains in the southern Kherson region and control of almost the entire eastern Kharkiv region, paving the way for its forces to enter the separatist stronghold of Lugansk.

“The de-occupation of the Lugansk region has already officially started,” regional governor Sergiy Gaiday said in a video posted on social media, dressed in camouflage and adding that several settlements had been liberated.

On Wednesday, Russian President Vladimir Putin signed into legislation his annexation of four Ukrainian territories — including Lugansk — as the EU agreed a new round of sanctions against Moscow in response.

Kremlin spokesman Dmitry Peskov said Moscow would take back land it lost to Kyiv within the annexed regions, vowing they would be “Russian forever and will not be returned.”

Putin last Friday signed agreements with the Moscow-installed leaders of the four regions to become subjects of the Russian Federation, despite condemnation from Kyiv and the West.

The four territories — Donetsk, Kherson, Lugansk and Zaporizhzhia — create a crucial land corridor between Russia and the Crimean Peninsula, which was annexed by Moscow in 2014.

Together, the five regions make up around 20 percent of Ukraine.

– ‘Strike back’ –

The Kremlin annexed the territories after hastily conducting referendums, denounced as void by Kyiv and its Western allies, but has yet to confirm what areas exactly of those regions are being annexed.

Russian forces do not have full control over Kherson or Zaporizhzhia and recently lost control of several settlements in Donetsk.

“The way we are regrouping (our forces) along the front means that we can gather strength and strike back,” Kirill Stremousov, the Moscow-appointed deputy head of Kherson region, told the RIA Novosti news agency.

Ukraine’s forces “won’t enter Kherson. Its impossible,” he said referring to the region’s eponymous main city.

On Tuesday, Ukrainian President Volodymyr Zelensky said his forces were making “rapid and powerful” gains and had retaken “dozens” of villages in the east and south.

The latest battlefield maps from Moscow showed that Russian troops had left many areas in Kherson, including along the west bank of the Dnipro River.

In Kharkiv, the maps indicated that Russian forces had almost entirely abandoned the east bank of the Oskil River, potentially giving the Ukrainians space to shell key Russian troop transportation and supply corridors.

While Russian authorities remain largely silent about the extent of the setbacks, war correspondents of pro-Kremlin media admitted that troops were in trouble.

“There won’t be any good news in the near future. Not from the Kherson front nor from Lugansk,” newspaper journalist Alexander Kots wrote on his Telegram channel with over 640,000 followers.

– ‘Chase them’ –

Near Lyman, a strategic transport hub in Donetsk that Kyiv recaptured over the weekend, a Ukrainian paratrooper told AFP that forces were “exhausted”.

“We’ll rest for a bit and then we will go further,” said the young, bearded soldier. “We will chase them,” he added.

On Tuesday, US President Joe Biden told Zelensky that another $625 million in military assistance was on the way.

The new batch includes more HIMARS multiple rocket launchers, which have allowed Ukraine to strike Russian command depots and arms stockpiles far behind the front line.

From the EU, there were no details about the nature of fresh sanctions agreed against Russia.

The latest package — the eighth since Russia’s invasion in February — is now going through a final approval procedure which, if no objections emerge, will be published and come into effect on Thursday, the Czech Republic’s EU ambassador said on Twitter.

Otherwise, Russia insisted that it should be part of an international probe into leaks in the Nord Stream pipeline that carries gas from Russia to Europe. Sweden has blocked off the area pending an investigation.

Moscow has accused the West of being behind blasts that lead to four leaks on the Baltic Sea pipelines.

Both Moscow and Washington have denied involvement.

US duo and Dane win Nobel for 'click chemistry'

5 Oct 2022 5 Oct 2022

A trio of chemists from the United States and Denmark who laid the foundation for a more functional form of chemistry where molecules are snapped together on Wednesday won the Nobel Chemistry Prize.

Americans Carolyn Bertozzi and Barry Sharpless, together with Denmark’s Morten Meldal, were honoured “for the development of click chemistry and bioorthogonal chemistry”, the jury said.

Bertozzi is the only woman among the seven Nobel laureates honoured so far this year, with women vastly under-represented in the history of the prizes, especially in the science disciplines.

The chemist — who as an undergraduate at Harvard played keyboards in a band called Bored of Education with future Rage Against the Machine guitarist Tom Morello — is only the eighth woman to win a Nobel Chemistry Prize, out of 189 recipients.

The award marks the second Nobel for 81-year-old Sharpless, who won the chemistry Nobel in 2001.

Only four other individuals have achieved the feat of winning two Nobel Prizes, including Polish-born Frenchwoman Marie Curie, who won the chemistry prize in 1911 after first winning the physics prize in 1903.

She was followed by American Linus Pauling who won for chemistry in 1954 and peace in 1962. American John Bardeen won the physics prize in 1956 and 1972, and Britain’s Frederick Sanger won the chemistry prize in 1958 and 1980.

– To make drugs, map DNA –

Click chemistry “is an elegant and efficient chemical reaction that is now in widespread use,” the jury said in a statement.

“Among many other uses, it is utilised in the development of pharmaceuticals, for mapping DNA and creating materials that are more fit for purpose,” it added.

Sharpless, a professor at Scripps Research in California, “started the ball rolling” and “coined the concept of click chemistry” around 2000, the jury said.

Afterwards, Sharpless and Meldal, a professor at the University of Copenhagen, “independently of each other, presented what is now the crown jewel of click chemistry: the copper catalysed azide-alkyne cycloaddition”.

The process allows chemists to “snap” molecules together like Lego bricks “with the help of some copper ions”, which among other things allow for the production of new materials.

“If a manufacturer adds a clickable azide to a plastic or fibre, changing the material at a later stage is straightforward,” the Nobel committee explained.

It is possible to click in substances that conduct electricity, capture sunlight, are antibacterial, protect from ultraviolet radiation or have other desirable properties, it said.

While there is widespread application of his research, Meldal said he was “very surprised and very proud” to receive the honour.

“There are so many good discoveries and developments in the world, it’s incredible to be in this situation,” Meldal told Swedish public radio.

– ‘A new level’ –

Bertozzi, 55, a professor at Stanford in the United States, was highlighted for then taking “click chemistry to a new level”.

“She developed click reactions that work inside living organisms. Her bioorthogonal reactions take place without disrupting the normal chemistry of the cell,” the jury said.

Her research is now being used to investigate how these reactions can be used to diagnose and treat cancer.

“I’m absolutely stunned, I’m sitting here and I can hardly breathe,” Bertozzi told reporters via telephone, minutes after the announcement.

Silvia Diez-Gonzaleza, a chemist who works on click chemistry at Imperial College, London, welcomed the win.

“Thank goodness” that the days of women not being allowed in chemistry labs are over, she told AFP, though “there is a lot of bias still out there”.

“I want to believe that it’s just a matter of time that as women and non-white people get more opportunities to achieve their potential, then eventually the recognition they get will be spread more widely.”

The Royal Swedish Academy of Sciences, which awards the Nobels in the science disciplines, has refused to introduce quotas despite the dearth of women laureates.

Goran Hansson, then-secretary general of the academy, told AFP last year after all of the science nods went to men, that it wanted every laureate to be accepted “because they made the most important discovery, and not because of gender or ethnicity”.

The lack of women laureates “reflects the unfair conditions in society, particularly in years past but still existing”, he acknowledged.

This year’s laureates will share the Nobel award sum of 10 million Swedish kronor (more than $910,000), and will receive the prize from King Carl XVI Gustaf at a ceremony in Stockholm on December 10, the anniversary of the 1896 death of scientist Alfred Nobel who created the prizes in his last will and testament.
