Ice shell thickness reveals water temperature on ocean worlds

Decades before any probe dips a toe—and thermometer—into the waters of distant ocean worlds, Cornell astrobiologists have devised a novel way to determine ocean temperatures based on the thickness of their ice shells, effectively conducting oceanography from space.

Climate extremes in Australia: New report analyzes major events of 2023

Scientists and researchers at the ARC Center of Excellence for Climate Extremes have today released "The State of Weather and Climate Extremes 2023" report. The report, co-written by more than 30 of Australia's leading climate scientists, including many of the Center's early career researchers, is designed to help decision makers and the general public understand the complexity of climate...

Parents, wealth, race drive girls' chances to play sports

The likelihood that a girl will participate in high school sports in the United States is driven not so much by individual choice, new research suggests. Instead, decisions made by parents, the wealth of one's family and community, and racial dynamics matter.

Odysseus traveled to the Moon, broke its leg, and still pinged Earth to tell the story

The lunar lander Odysseus, which touched down softly — if somewhat awkwardly — on the Moon last week, is alive and well. But after nearly a week of returning science data, it is running low on power and will soon be put to sleep. “What we are going to do is tuck ‘Odie’ in forContinue reading "Odysseus traveled to the Moon, broke its leg, and still pinged Earth to tell the story" The post...

The hidden driver of the ride-sharing economy

When Greg Buchak was a graduate student at the University of Chicago, Uber and Lyft were just beginning to spread across the country. Since he didn't own a car, he found the ride-sharing apps convenient for short and long trips. Yet as a financial economist in training who studied borrowing and lending, Buchak began an ongoing debate with his friends: Were these new services actually good for...

Benefits messaging boosts consumer plant purchasing

A deeper understanding of the relationship between plant benefits, consumer perceptions, and demographic differences is important when shaping marketing strategies for communicating the benefits of plants. In the ornamental plant industry, plant benefits are numerous and diverse; however, their influence on consumer behavior and how that varies by age is not well understood. A new study expands...

Fewer fish, worse health: The climate effect

Over the next 25 years, reduced intake of marine food resources due to climate change will likely have a negative impact on the cardiovascular health of First Nations on Canada's Pacific coast, a new study suggests.

Scientist fed classified information to China, says Canada intelligence report

Scientists discover radiation from massive stars shapes planetary systems

How do planetary systems such as the solar system form? To find out, CNRS scientists taking part in an international research team studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope. By observing a protoplanetary disk named d203-506, they have discovered the key role played by massive stars in the formation of such nascent planetary systems.
