While we were stockpiling, here's what astronauts were up to in space last week – CNN

While many of us are practicing social distancing, working from home or living in quarantine-like and isolated situations, life goes on as normal for the space station-dwelling astronauts.
They’re aware of the pandemic and have been sharing their support for people across the globe through their Twitter accounts. NASA astronaut Jessica Meir shared her perspective: “From up here, it is easy to see that we are truly all in this together. #EarthStrong.”
But the astronauts aren’t just floating around and taking cool pictures of Earth. Each week, hundreds of science experiments are in progress on the station. In addition to working on these experiments, the astronauts study themselves to better understand the human body in space.
Here’s a look at the cool science they’ve been doing 254 miles from Earth.

Space pants

Living in space is an adjustment for the human body as it adapts to the lack of gravity.
Over the years, astronauts have noticed changes in their vision as a response to the headward fluid shift they experience. This also increases pressure in the head.
Last week, NASA astronauts Jessica Meir and Andrew Morgan, as well as Russian cosmonaut Oleg Skripochka, tested out the Russian Chibis hardware, also known as the Russian Space Agency’s Lower Body Negative Pressure experiment.
It’s basically a pair of pants housed in the Russian Orbital Segment of the space station.
The rubber pants use suction to draw fluids back down towards the legs and feet, just like we experience walking on Earth.
Researchers hope that hardware to reverse the fluid shift astronauts experience in space could also help with their vision changes.
While Morgan was wearing the Chibis pants, Meir used a tonometer to measure his eye pressure, with doctors on Earth watching in real time. Morgan’s head and chest were also scanned to monitor blood flow.
The astronauts also tested their hearing as part of the European Space Agency’s Acoustic Diagnostics experiment to monitor if the astronauts’ hearing changes in response to noise and lack of gravity on the station.

Heart, muscle and bone

Multiple experiments are currently occurring on the station that could not only benefit the health of astronauts, but human life on Earth as well.
Two different experiments are focused on growing healthy heart cells from stem cells to see if they grow easier and quicker in the absence of gravity.
These cells could treat astronauts who experience heart abnormalities and be used to treat people and children with cardiac diseases and disorders on Earth. The cells can also be used to investigate the development of new pharmaceuticals.
One experiment, called Engineered Heart Tissues, allows the astronauts to watch heart cell muscle contractions in real time.
Meir and Morgan have been taking care of the heart cells, watching how they react to the lack of gravity. When the heart cells return to Earth, the results of the space experiment will be compared with a similar control experiment on Earth.
The astronauts have also been studying bone samples to understand and develop bone treatments for astronauts who suffer bone loss in space, as well as people diagnosed with osteoporosis on Earth. The goal is to determine new treatments for both.
Mice are also sharing space on the station with the astronauts in a mouse habitat so they can study how the mice and their gene expression reacts to zero gravity.
Understanding how their gene expression is altered can help NASA better prepare for long-term human spaceflight. The study also serves a secondary purpose of allowing them to determine countermeasures for muscle atrophy, which can occur in space or for patients on bed rest.

It’s all in your gut

Astronauts don’t get much of a chance to vary their diets in space. That means they could also be missing out on vital nutrients and other added benefits of the fresh food we consume on Earth.
The Japanese space agency’s Probiotics investigation is studying how good gut bacteria could improve the human microbiome on long-term missions.
Meanwhile, the astronauts are also participating in an experiment called Food Acceptability, looking at the “menu fatigue” that happens when they eat based on limited options over months on the station. This usually causes them to lose weight by the time they return to Earth.
Fortunately, the astronauts are also actively growing lettuce in space and so far, it’s proven safe to eat. The ability to grow fresh produce in space could be a game changer for astronauts on long missions going forward.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

This report by The Canadian Press was first published Sept. 9, 2024.
