Sports in the United States look very different than they did when the nation was founded 250 years ago, according to Mark Dyreson, professor of kinesiology and history at Penn State. But one thing has remained constant—sport has played a vital role in shaping and reflecting the country's culture and values, he said.

Few would have predicted Morocco's success at the 2022 Fifa World Cup. Heading into the tournament, they were ranked 22nd in the world and had never progressed beyond the round of 16.

A new study by Mannheim Business Administration professor Hartmut Höhle examines the reactions of actual victims of the Cambridge Analytica scandal on Facebook over a longer period. Its key finding is that, despite being affected by data fraud, users remain on the platform.

Big Talks for Little People, an innovative child mental health support program, has helped alleviate bullying that had been reported by students in Out of School Hours Care (OSHC), according to a new study conducted by Flinders University researchers.

Amid growing public concern about the radicalization of young people, there is a widespread misconception that radicalization logically and inevitably progresses to violence.

Luxury brands have increasingly embraced internet memes in their social media advertising campaigns. For example, Gucci's #TFWGucci campaign demonstrated how luxury brands can incorporate memes into their digital communication strategies to capture consumers' attention. Memes—digital content that spreads rapidly through sharing, imitation and adaptation across online communities—have become a popular way for brands to engage consumers.

The words "tick-tock," "hiss" and "screech" are examples of onomatopoeia because they imitate the sounds they represent: the rhythmic ticking of a clock; an angry cat, or a slowly deflating bike tire; a high-pitched scream. Onomatopoeia is a type of sound symbolism.

Magnetic fields may be the hidden force bringing both newborn stars and giant black holes together. New computer simulations suggest that magnetic fields play a crucial role in helping pairs of young stars form. The findings could explain why binary star systems are so common throughout the Milky Way and may even offer clues about [...]

Incorporating more plant-based proteins could help people save on their grocery bill, but new research has found that it's not so simple when it comes to choices at the supermarket. Simon Fraser University researchers peeked into more than 87,000 grocery carts in Canada and Finland to study how much price influenced the type of protein people bought: animal-based or plant-based. Researchers discovered that while the price had to be right, having a variety of options also played a role.

Americans rarely marry outside of their race or class in a nation where residential segregation is relatively common. It is a dynamic widely viewed as a contributing factor to income inequality and intergenerational social mobility.

Since NASA’s Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the Moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and provide a blueprint for how future missions will conduct science on the lunar surface as NASA builds a Moon Base and develops an enduring human presence there.

Postflight crew health, performance data

In the hours, days, and weeks after landing, the Artemis II crew members, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, contributed critical data to help the agency understand how the human body reacts to spaceflight. Collecting this data as soon as possible after landing was important to understand how the body adapts from microgravity to Earth’s gravity. The data will inform NASA’s understanding of how quickly crews can complete mission-critical tasks after landing on a planetary surface like the Moon or Mars, where there won’t be landing support personnel to assist.  

Within a day of splashdown, researchers collected a suite of data for the Artemis II Spaceflight Standard Measures study, which is part of a larger effort across the astronaut corps to gather a baseline set of health measurements on blood pressure, heart rate, eye health, and motor control. Crew members also completed a mini obstacle course, which included lying down, standing up, unfurling a rope ladder, ladder climbing, and more, to assess how their bodies were adapting to Earth’s gravity.

Once the crew returned to NASA’s Johnson Space Center in Houston, researchers guided them through further medical check-ups and tests of motor control. Over the next several days, the crew completed obstacle courses wearing spacesuits offloaded to lunar gravity, which is roughly one-sixth the force of Earth’s gravity. Researchers are now analyzing this data to gain insight into how crews may perform as they adapt to the gravity of a planetary surface.

As part of the Immune Biomarkers study, researchers are comparing blood and saliva samples collected after the Artemis II splashdown with samples collected preflight and during the mission. Among other topics, the study investigates whether and how dormant viruses reawaken in astronauts’ bodies while in space.

Some crew members completed postflight cognition tests and a simulated manual spacecraft docking task to assess motor control for the ARCHeR (Artemis Research for Crew Health & Readiness) study. This, combined with data collected through a wrist-worn device while crew members were in space, is used to understand the effect of space hazards on well-being and performance.

Initial data collections for Artemis II health studies concluded 45 days after splashdown. However, medical teams will continually monitor astronaut health throughout the Artemis II crew members’ lifetimes.

Once this data is processed and anonymized, information will be available for scientists to study the effects of spaceflight via a request to NASA’s Life Sciences Data Archive. The results from this work could lead to new technologies and studies that help predict the adaptability of crews on future missions to the Moon and Mars.

Analyzing astronaut-derived organ chips flown around Moon

Organ chips from NASA’s AVATAR (A Virtual Astronaut Tissue Analog Response) investigation are being analyzed at chip developer Emulate’s laboratory in Boston. The organ chips included bone marrow cells from each Artemis II astronaut. They flew around the Moon with the astronauts, and now researchers are studying these organ chips to determine how deep space radiation and microgravity affect human health at the molecular level.

Scientists are comparing the chips flown aboard the spacecraft to ground controls and crew blood samples using advanced techniques, including single-cell RNA sequencing. The analysis will characterize how organ chips model individual responses to spaceflight, which is data that could allow NASA to send future astronauts’ AVATAR chips ahead on missions to develop personalized medical kits. The researchers plan to share early findings at scientific conferences while full analysis continues.

Lunar imagery, audio for data release

On April 6, the Artemis II crew members studied features on and around the Moon for nearly seven hours during Orion’s closest approach to the lunar surface. Their work was guided by a minute-by-minute observation plan developed by the Artemis II lunar science team.

Scientists are reviewing the data collected from the mission, which includes images, video, and audio files, to release a report of their initial data interpretations later this year. The report will cover observations of impact flashes, variations in color on the lunar surface, and the shape and texture of faults and ridges. The team also will publish a report on how Artemis II lunar science observations were planned, organized, and executed for the benefit of future Artemis missions.

NASA will publish more than 100 science-related audio recordings with transcripts, as well as approximately 11,500 Earth and Moon image and video files from the mission science campaign, with accompanying data. While many of these images already are public, these records will be available through NASA’s Planetary Data System, a public archive of data from all of NASA’s planetary missions. To get the data ready, the team is converting files into standard formats that anyone can easily open and add information to make the data searchable in NASA’s archive for generations to come.
