Nasa names 4 astronauts on moon mission

Published

on

The US space agency Nasa has named the four astronauts who will take humanity back to the Moon, after a 50-year gap.
Christina Koch will become the first woman astronaut ever assigned to a lunar mission, while Victor Glover will be the first black astronaut on one.

They will join Reid Wiseman and Jeremy Hansen to fly a capsule around the Moon late next year or early in 2025.

The astronauts won’t land on the Moon, but their mission will pave the way for a touchdown by a subsequent crew.

The three US citizens and one Canadian were presented to the public in a ceremony in Houston, Texas.

They will now begin a period of intense training to get themselves ready.

In selecting a woman and a person of colour, Nasa is keeping its promise to bring greater diversity to its exploration efforts. All the previous crewed missions to the Moon were made by white men.

Reid Wiseman (47): A US Navy pilot who served for a time as the head of Nasa’s astronaut office. He’s flown one previous space mission, to the International Space station in 2015.

Victor Glover (46): A US Navy test pilot. He joined Nasa in 2013 and made his first spaceflight in 2020. He was the first African American to stay on the space station for an extended period of six months.

Christina Koch (44): An electrical engineer. She holds the record for longest continuous time in space by a woman, of 328 days. With Nasa astronaut Jessica Meir she participated in the first all-female spacewalk in October 2019.

Jeremy Hansen (47): Before joining the Canadian Space Agency, he was a fighter pilot with the Royal Canadian Air Force. He has yet to fly in space.

“The Artemis-2 crew represents thousands of people working tirelessly to bring us to the stars. This is their crew, this is our crew, this is humanity’s crew,” said Nasa Administrator Bill Nelson.

“Nasa astronauts Reid Wiseman, Victor Glover, and Christina Hammock Koch, and CSA astronaut Jeremy Hansen, each has their own story, but, together, they represent our creed: E pluribus unum – out of many, one. Together, we are ushering in a new era of exploration for a new generation of star sailors and dreamers – the Artemis Generation.”

Wiseman will be the commander; Glover will be his pilot; Koch and Hansen will act as the supporting “mission specialists”.

The quartet are essentially repeating the 1968 mission carried out by Apollo 8, which was the first human spaceflight to reach the Moon.

Its crew took the famous “Earthrise” picture that showed our home planet emerging from behind the lunar horizon.

Israeli embassy couple shot dead in Washington

Published

Shooting suspect Elias Rodriguez has been charged with two counts of first-degree murder after two Israeli embassy staff were killed in Washington DC on Wednesday night.

Sarah Lynn Milgrim and Yaron Lischinsky were leaving an event at the Capital Jewish Museum when they were shot dead.

Rodriguez, a 30-year-old from Chicago, was detained at the scene. More charges could come later, law enforcement officials say, and the FBI is aware of “writings” purported to be from the suspect.

Police say the suspect was in town for a work conference, and shouted “free Palestine” after being taken into custody.

US President Trump says the attack is “so sad” and “based obviously on antisemitism”, while DC Mayor Muriel Bowser says “this crime will not be tolerated in our city”.

Israel’s Prime Minister Benjamin Netanyahu has linked the shooting to the 7 October 2023 attack and says security will be increased at Israeli embassies worldwide.

‘Shrinking Nemo’: Smaller clownfish sound alarm on ocean heat

Published

on

By

Fish similar to those made famous by the movie Finding Nemo are shrinking to cope with marine heatwaves, a study has found.

The research recorded clownfish living on coral reefs slimmed down drastically when ocean temperatures rocketed in 2023.

Scientists say the discovery was a big surprise and could help explain the rapidly declining size of other fish in the world’s oceans.

A growing body of evidence suggests animals are shape shifting to cope with climate change, including birds, lizards and insects.

“Nemos can shrink, and they do it to survive these heat stress events,” said Dr Theresa Rueger, senior lecturer in Tropical Marine Sciences at Newcastle University.

The researchers studied pairs of clownfish living in reefs off Kimbe Bay in Papua New Guinea, a hot spot of marine biodiversity

The wild clownfish are almost identical to the ones depicted in the movie Finding Nemo, in which a timid clownfish living off the Great Barrier Reef goes in search of his son.

The scientific study took place in the summer of 2023, when temperatures shot up in the oceans, leading to large swathes of coral turning white.

The scientists took multiple measurements of individual clownfish coping with the heat.

They found the tiny fish didn’t just lose weight but got shorter by several millimetres. And it wasn’t a one-off – 75% of fish shrunk at least once during the heatwave.

Dr Rueger explained: “It’s not just them going on a diet and losing lots of weight, but they’re actively changing their size and making themselves into a smaller individual that needs less food and is more efficient with oxygen.”

The fish may be absorbing fat and bone, as has been seen in other animals, such as marine iguanas, although this needs to be confirmed through laboratory studies.

Dr Rueger joked that a little bit of movie rewriting might be necessary, with a new chapter ahead for Nemo.

“The movie told a really good story, but the next chapter of the story surely is, how does Nemo deal with ongoing environmental change?” she told BBC News.

Global warming is a big challenge for warm-blooded animals, which must maintain a constant body temperature to prevent their bodies from overheating.

Animals are responding in various ways: moving to cooler areas or higher ground, changing the timing of key life events such as breeding and migration, or switching their body size.

The research is published in the journal, Science Advances.

World-first gonorrhoea vaccine launched by NHS England

Published

on

By

England will be the first country in the world to start vaccinating people against the sexually transmitted infection gonorrhoea.

It will not be available for everyone. The focus will mainly be on gay and bisexual men with a history of multiple sexual partners or an STI.

The vaccine is 30-40% effective, but NHS England hopes it will reverse soaring numbers of infections.

There were more than 85,000 cases in 2023 – the highest since records began in 1918.

Gonorrhoea does not always have symptoms, but they can include pain, unusual discharge, inflammation of the genitals and infertility.

How many people will choose to be immunised is uncertain.

But projections by Imperial College London show that if the jab proves popular then it could prevent 100,000 cases and save the NHS nearly £8m over the next decade.

Max, a sexual health campaigner, told BBC Newsbeat he would “100%” take the vaccine after being diagnosed with gonorrhoea twice within a year.

“I think this is great that it’s been announced”, he says, adding: “It’s going to take the pressure off the clinics, it’s just a big win all round.”

Vaccination will start in August and will be offered through sexual health services.

Public Health Scotland said it was also working on plans to launch its own programme for high-risk individuals.

BBC Newsbeat has asked health bodies in Wales and Northern Ireland whether they intend to do the same.

Is it effective enough?

This vaccine wasn’t designed for gonorrhoea. It’s the meningitis B vaccine currently given to babies.

But the bacteria that cause the two diseases are so closely related that the MenB jab appears to cut gonorrhoea cases by around a third.

That will require a delicate conversation in sexual health clinics as the vaccine will not eliminate the risk of catching gonorrhoea. It is normally caught while having sex without a condom.

But Prof Andrew Pollard, the chair of the Joint Committee on Vaccination and Immunisation (JCVI), which recommended the vaccine, said despite it only being 30% effective, it was “worth having” and could have “a huge impact” overall.

The decision is not just about the record numbers of cases. Gonorrhoea is becoming increasingly difficult to treat.

Most cases are treated with a single dose of antibiotics, but there is an 80-year history of the bacterium which causes gonorrhoea repeatedly evolving resistance to our antibiotics.

It’s happening to the current treatments too and is why some doctors are concerned gonorrhoea could one-day become untreatable.

The best way to deal with a drug-resistant infection is to never catch it in the first place.

Dr Amanda Doyle, from NHS England, said: “The launch of a world-first routine vaccination for gonorrhoea is a huge step forward for sexual health and will be crucial in protecting individuals, helping to prevent the spread of infection and reduce the rising rates of antibiotic resistant strains of the bacteria.”

The people most affected by gonorrhoea in the UK are those aged 16-to-25, gay and bisexual men, and those of black and Caribbean ancestry.

The vaccine – which costs around £8 per dose – is value for money when primarily offered to gay and bisexual men, rather than all teenagers.

However, clinicians do have the freedom to use their own judgement and offer the vaccine to people using sexual health services they think are of equally high risk.

People will be offered mpox (formerly known as monkeypox), HPV and hepatitis vaccines at the same time.

Prof Matt Phillips, president of the British Association for Sexual Health and HIV, said: “This is excellent news and a landmark moment for sexual health in England.

“Gonorrhoea diagnoses are at their highest since records began and this has the potential to help us to turn that around.”

It is not known how long the protection provided by the vaccine will last or how often booster jabs might be required.

The decision comes almost a year and a half after a vaccination programme was recommended by the UK’s JCVI.

Sexual health campaigners had criticised that long wait, but have welcomed this decision.

Katie Clark, head of policy and advocacy at the Terrance Higgins Trust, called it a “huge win”.
