Rachel Feltman: Happy Monday, listeners! For American scientific‘s Science quickly, I’m Rachel Feltman. Let’s start catching some news of science lost per week.
We will start with a space update we have waited for about nine months …

Feltman: Butch Wilmore and Suni Williams have finally returned to the ground. Two NASA astronauts, with the aim of spending about a week at international space station, but has been there since June Last Tuesday evening in a space capsule. Welcome home, Butch and Suni!
If you were asking why he was asking, after the initial technical difficulties of the vehicles arriving, the answer is not very exciting, it basically fell to programming issues. First, the NASA had to throw two other astronauts from the next task, return the vehicle to be a place for Butch and Suni. Once he The mission took him to the station, he had to put it after The role was created to relieve the previous crew of their duties. Space is hard, as people often say, and it means a lot of delays over several missions.
Other news in space, last week scientists presented images of a planet system far from 130 years away James Webb SPACE Telescope. For the first time, JWST was able to directly catch the images of carbon dioxide gas in an exoplanet. This means that Jwste’s promise to stimulate chemistry from the planet atmosphere from a distance. These observations suggest that four planets in the system, known as HR 8799, is likely to be a process called Core Accretion. This process begins with the formation of solid nuclei to attract gas inside the protoplan album. Saturnor and Jupiter formed the same way. In 30 million years, a baby HR 8799 is approximately our 4.6 million solar system. So examine these foreign worlds for our own criminals what seemed like in their early days. And by talking to the first day, Jwst will still come. The space telescope would last for at least five years, But hope is more than 20.
Now let’s catch up with the environmental protection agency. Around last week’s news, i Explain EPA head Lee Zellin plans to undo environmental legislation. I also mentioned his intention to cut 65 percent of the agency costs. Last week, Democrat thanks to the documents reviewed on the Committee on Science, Space and Technology, we got a clearer picture of these cost cutting cutting measures.
A New York Times new Last Monday EPA plan requires 1,155 scientists to shoot, as well as to get rid of the research and development office. This is the main science of the Epa’s main arm, researching environmental issues such as pollutants and humans. Zellin said The appearance of the fox business on Tuesday EPA was still “working” through cost cutting decisions. On Tuesday, representatives of Valerie Fouckee, Deborah Ross and Zoe Lofgren, are all members of the home science, space and technology committee. Put the joint expression It condemns the supposed plans. They argued that, taking into account the duty to use the best available for its decisions, it would be illegal by eliminating its main branch of science. If you like having clean air and water, you can think Calling your congresses repetitions To apply for a stand.
Meanwhile, President Donald Trump published in social truth, his owner platform, authorized his administration “immediately to start producing energy with beautiful coal and clean.”
“Clean Coal” It is a nebulous term It is up to the technologies that pollute coal is more than those would be without these technologies. But there is no way to manipulate the coal that makes it a clean form of energy. There are some facilities that use carbon capture technology to alleviate the impact of coal effect in the environment, but this technology is expensive and lemme is very clear, not compared to the coal zero carbon energy. It is coal The most polluting source of energy. Releases the carbon dioxide pileIt helps environmental issues such as acid rain and smog and can cause lung disease.
In social truth, Trump president claimed “Environmental extremities” and “Thugs” in other countries, especially in China, to achieve economic advantages in the US, opening new coal plants. It’s true China has opened new coal plants In recent years, mention worth mentioning the percentage of electricity generated by the country’s coal It really is declining.
Is also Highlights has been the World Meteorological Organization last Wednesday reported these levels of carbon dioxide in the atmosphere They are 800,000 years old. So consider calling your repetitions!
No particular reason, I could use a little breath. Let’s talk about animals to make the rest of the passage.
First of all, have you ever wondered how to avoid preventing stamps? You should be completely surprised that they cause gray stamps, for example, May hold breaths more than an hour. A study Posted last Thursday Science How it can help explain. Apparently, the gray stamps seem to be so much oxygen in a certain point in a given time.
Like most mammals, humans don’t necessarily react to the lack of oxygen in the air. We are much more sensitive At our carbon dioxide levels, those who ask us to breathe more. When a gray stamp began to get the sensation of air hunger, CO2 saturation began to breathe in their blood while they were breathing, they would never do anything. It seems, however, that they have a trick: simply cut the midfielder and feel directly oxygen.
Scientists tested, giving seals with different levels of oxygen and carbon dioxide before the animals go to their divers. Researchers found the stamps to immerse longer after inhaling of richer oxygen air and cut the short diver after less oxygen. When stamps breathe with a high level of carbon dioxide, he didn’t really change the length of the diver.
While this study saw Gray stamps, there are no divers in the world of stamps. Northern elephant seal At the same time it can be immersed in two hours. It is likely that this feature of oxygen sensation is quite remote ancestor applied to more than mammals. After all, Emperor penguin It can be under 27 minutes under water.
And talking about the penguin, his poop causes great ruckus in the world of Zooplankton. A Analysis published last Thursday Limits in Sea SciencesResearchers were zoomed in Krill Antarctic behavior. Small and small creatures are key members of the food chain, so they spend a lot of time to eat. Scientists knew that the Krills had already used a sense of smell of food and reacting with things like food, so they thought naturally: “Why not try Penguin Poo?” Sure enough, if they suffer from seawater in a Guano tank, small critics swim faster, turning more directions and ate less algae. It may be wondering why scientists are interested in this crap. Literally, like this shit. But the potential of Killsen’s place, food chain and the ability to seize carbon, these little boys can have a great influence on the ocean. Krill are already changing their behaviors by moving climate change, loss of sea ice and the acidification of the ocean further south.
If you need a me-up this week, you don’t have to thank the penguin Dody duty: researchers had to gather a couple of things to study, and apparently it smells wise exploits.
That’s about this week’s news. We will return on Wednesday to talk about changing sciences of invasive plants. And be careful Friday for a very special video passage. We give you a rotate lab of the first-edge lab that scientists do MIT (Massachusetts Institutes) scientists in Nanoscale.
