NASA's SPHEREx team rings bell at New York Stock Exchange
Members of NASA's SPHEREx mission team celebrated Earth Day and the recent launch of the astrophysics observatory by ringing the closing bell for the New York Stock Exchange on April 22, 2025.
This photo captures the moment that Michael Thelen, NASA's flight system manager for the SPHEREx observatory, rang the closing bell for the New York Stock Exchange on Earth Day, April 22, 2025. Joining him for the honor were other members of the Jet Propulsion Laboratory (JPL) team, as well as team members from BAE Systems Inc., Space & Mission Systems, which built the telescope and spacecraft's main structure, known as a "bus."At 4:00 p.m. EDT (2000 GMT) on Tuesday, trading as normal came to an end as the brokers on the stock exchange floor below gathered to hear the bell ding at Thelen's command.
The New York Stock Exchange (NYSE) located in the Financial District of Lower Manhattan in New York City.SPHEREx (or Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is in a sun-synchronous, low Earth orbit, circling the planet at about 430 miles (700 kilometers) above the surface. It was launched from Vandenberg Space Force Base in southern California on March 12, 2025.
Although this is not the first time that NASA has been invited to ring the bell at the New York Stock Exchange (or NASDAQ), it is still not as common as having businesses who are part of the market or other newsmakers receive the honor. What is amazing is what the SPHEREx mission promises to answer. SPHEREx was built and launched to collect data on more than 450 million galaxies and 100 million stars in the Milky Way. The information transmitted back to Earth will help improve scientists' understanding of how the universe evolved, while searching for key ingredients for life in our galaxy.

Apheresis May Sweep Microplastics From Veins
Microplastics are particles ranging from 1 micrometer to 5 millimeters in diameter, and nanoplastics, which are even smaller, are found in virtually every environment on Earth, from mountain peaks to ocean depths, and from the smallest animals in the food chain to human brain cells. These particles can originate from the breakdown of larger plastic items or be intentionally manufactured for use in products, such as cosmetics, synthetic fabrics, and pharmaceuticals. Recent studies suggest that the human brain may contain up to a teaspoon of microplastics and nanoplastics, with the tiniest fragments primarily composed of polyethylene, the same material commonly used in plastic bags and food packaging. These particles have been detected in areas such as the walls of blood vessels in the brain and within immune cells. However, it remains unclear whether microplastics contribute to the progression of neurological diseases or whether these conditions render the brain more susceptible to particle infiltration. In animal studies involving fish and rodents, prolonged exposure to nanoplastics has been linked to memory impairment, brain inflammation, and alterations in synaptic protein levels. Beyond the brain, microplastics have been found in human feces, arterial plaques, and even the placenta. A study published in The New England Journal of Medicine linked the presence of microplastics in the arteries to a heightened risk for heart attack, stroke, and overall mortality. Therapeutic Apheresis According to a preliminary study published in Brain Medicine by researchers at Technische Universität Dresden in Dresden, Germany, therapeutic apheresis, a medical procedure that filters tiny particles from the blood, may help remove microplastics from the human body. The technique can capture particles as small as 200 nanometers, which is approximately 5000 times smaller than a millimeter. In this study, the researchers evaluated the procedure in patients with myalgic encephalomyelitis, also known as chronic fatigue syndrome. They analyzed the waste fluid discarded during apheresis using a specialized infrared spectroscopy technique. The analysis detected substances that matched the chemical signatures of polyamide and polyurethane, two common types of industrial plastics. This suggests that microplastics may have been successfully removed from the blood of patients during the procedure. Notably, this study did not measure the total amount of microplastics removed or compare their levels in patients before and after apheresis. What has been demonstrated so far is the presence of microplastics in the waste material discarded by the device — an observation that suggests, but does not yet confirm, the effective removal of these substances from the human body. Researchers have cautioned that the detected materials may reflect chemical structures common to proteins, meaning that further analysis is required to verify the exact nature of the removed particles. Nonetheless, the findings offer hope to researchers seeking to address the growing accumulation of microplastics in the human body. The authors recommended conducting studies with larger groups and quantitative analyses comparing the levels of microplastics in the blood before and after the procedures. The authors concluded that 'such analyses will help determine particle removal from blood and tissues and assess correlations with symptom improvement in conditions like myalgia encephalomyelitis/chronic fatigue syndrome.' Alternative Approaches Currently, evidence that microplastics are effectively removed from the human body after ingestion is limited. A 2011 study examined bisphenol A (BPA) levels in blood, sweat, and urine samples from 20 individuals. In 16 cases, BPA appeared only in sweat, suggesting that induced perspiration may help eliminate certain compounds from the body. However, more studies are needed to assess its long-term safety and efficacy. 'That is why we focus on reducing exposure to microplastics in the first place,' said Nicholas Fabiano, MD, a psychiatry resident at the University of Ottawa, Ottawa, Ontario, Canada, and co-author of a related article in Brain Medicine . The challenge of this research began with tracking the effects of microplastic particles. 'From a clinical perspective, it is very difficult to establish a direct link between exposure to microplastics and adverse health outcomes,' said Fabiano. To address this, he advocated the creation of new tools to measure dietary risks, such as a dietary microplastic index. 'We propose the development of a Dietary Microplastic Index that could be integrated with existing dietary risk assessment tools to estimate microplastic exposure based on the types of food consumed,' he said.

The ISS menu is about to get a lot more interesting
The first person to consume food in space was Soviet cosmonaut Yuri Gagarin, who during his brief time in orbit in 1961 had the unenviable pleasure of devouring a meal of beef and liver paste squeezed from an aluminum tube. It sounds awful, because it almost certainly was. Over the decades, however, astronaut food has steadily improved, and while some dishes continue to require rehydration in foil packets, others actually bear some resemblance to what you might eat back on terra firma — although this sushi 'meal' doesn't really cut it. Recommended Videos French astronaut Sophie Adenot is one of the lucky ones. When she heads to the International Space Station (ISS) next year, she's going to be taking with her some top-class nosh created by award-winning Michelin-starred chef Anne-Sophie Pic. Taking a welcome break from freeze-dried scrambled eggs and powdered soups, Adenot and her ISS crewmates will get to enjoy tasty dishes such as parsnip velouté with curry and smoked haddock, onion soup with pink peppercorns and gratinéed croutons, and lobster bisque with crab and caraway — and they're just the starters. While most meals aboard the ISS are basic fare from cans or vacuum packs, every so often a special 'bonus meal' is prepared for all of the astronauts to enjoy together, partly to help with crew bonding, and partly to give everyone a welcome break from the blander menu items. 'During a mission, sharing our respective food is a way to invite our crewmates to discover more about our culture,' Adenot said. 'It's a very special bonding moment for all of us and a welcome change in our day-to-day routine. I have no doubt they'll be as enthusiastic as I am when they get a chance to taste Anne-Sophie's dishes.' When creating the one-off menu, Pic had to consider strict rules for food aboard the ISS. For example, dishes have to be solid or contained so that crumbs or small bits don't float away in the microgravity conditions and clog up the space station's ventilation systems. 'Cooking for space means pushing the boundaries of gastronomy,' Pic said. 'With my team in my research and development lab, we embraced a thrilling challenge: preserving the emotion of taste despite extreme technical constraints.' As NASA looks toward the first crewed missions to Mars and beyond, astronauts have also been experimenting with growing produce in microgravity, providing them with fresh food as part of a sustainable life-support system, while also boosting crew morale.

Astronomers track object that may have originated outside the solar system
CAPE CANAVERAL, Fla. (AP) — Astronomers are monitoring an object headed our way that may have wandered over from another star system. Scientists have discovered what might be only the third known interstellar object to pass through our solar system, the European Space Agency said Wednesday. The harmless object is currently near Jupiter hundreds of millions of miles (kilometers) away and moving toward Mars, but it should get no closer to the sun than that, according to scientists. It's too soon to know whether the object, designated for now as A11pl3Z, is a rocky asteroid or a icy comet, or how big and what shape it is. More observations are needed to confirm its origins. NASA said it is monitoring the situation. Astrophysicist Josep Trigo-Rodriguez of the Institute of Space Sciences near Barcelona, Spain, believes it is an interstellar object based on its odd path and extreme speed cutting through the solar system. He estimates its size at roughly 25 miles (40 kilometers) across. The first confirmed interstellar visitor was in 2017. It was dubbed Oumuamua, Hawaiian for scout, in honor of the observatory in Hawaii that discovered it. Classified at first as an asteroid, the elongated Oumuamua has since showed signs of being a comet. The second object confirmed to have strayed from another star system into our own is 21/Borisov, discovered in 2019 and believed to be a comet. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.
