The last turn of 'Ezekiel's Wheel' honors a fossil hunter
The mystery of Ezekiel's Wheel—the extinct sea creature, not the Biblical vision—may have taken its final turn, thanks to Yale paleontologists. In so doing, the researchers have also finally put a scientific name to the favorite fossil of a beloved amateur fossil hunter.
STEM Career Days boost high school students' career aspirations in STEM fields, study finds
A new study at the University of Missouri—in partnership with Harvard-Smithsonian researchers—shows that when colleges host "STEM Career Days," the students who attend are far more likely to pursue a career in a STEM (Science, Technology, Engineering and Math) related field.
A comprehensive approach to tackling pollution in Houston and beyond
With its notoriously hot and humid climate and robust industrial environment, Houston is one of the most ozone-polluted cities in the United States. Now, a University of Houston research team is integrating the power of machine learning (ML) with innovative analysis techniques to pinpoint the city's air pollution sources more accurately.
Once they have laid their eggs, fish become 'young' again: Study
The physical relief—in body weight—that temperate fish like cod and Atlantic herring experience after they spawn for the first time allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in body weight.
Q&A: 'Hot hand' in sports is real, but there's a catch
Fans and players both feel it in the gut when the "hot hand" shows up in sports. Something special is happening that can't be explained. Cross your fingers the streak continues.

On Oct. 4, 1923, Edwin Hubble took a photographic plate of the Andromeda Nebula (as it was known then) using the 100-inch Hooker telescope at Mount Wilson. The next night, he took another plate and found that a star that seemed to belong to the nebula had changed in brightness. At first, he thought thisContinue reading "How Edwin Hubble unlocked the cosmos: This Week in Astronomy with Dave...
New algae species rewrites understanding of reef systems
A discovery has been made in the heart of the world-renowned Great Barrier Reef and unique reefs systems of the Coral Sea and Lord Howe Island, leading to a greater understanding of how the world heritage-listed landmark is protected.
Study examines the relationship between mice and a plant that flowers once a century
Researchers at Nagoya University in Japan have revealed new insights into the interaction between mast seeding plants and the animals that eat their seeds. Hanami Suzuki and Professor Hisashi Kajimura examined the behavior of field mice using seeds from once-in-a-century flowering sasa bamboo plants in central Japan.
Researchers create a breathable alveolus in vitro
Researchers from Zhejiang University have successfully constructed biomimetic alveoli outside the human body that can replicate the process of human breathing.
Food waste prevention in Europe can generate major footprint savings
New research shows that European food consumption draws unnecessarily excessively on global resources, which is why researchers are calling for political action. Many of the foods that are consumed in Europe are produced in countries outside Europe. Food loss—and waste later in the chain—occurs along the food supply chain, from the primary agricultural sector in Europe or rest of the world,...
The first assimilation of CryoSat-2 summer observations provides accurate estimates of Arctic sea ice thickness
Scientists have improved a data assimilation system for better estimating Arctic summer sea ice thickness (SIT) by assimilating satellite-based summer SIT and ice concentration data with an incremental analysis update (IAU) approach. Their study shows promising results for the improved estimations of Arctic SIT by assimilating the latest breakthrough of satellite-retrieved SIT for summer in the...
Researchers supply significant genomic insight into tar spot on corn
First reported in 2015, tar spot is an emerging disease on corn that has rapidly spread across the United States and Canada, causing tremendous yield loss estimated at $1.2 billion in 2021 alone. Tar spot gets its name from its iconic symptoms that resemble the splatter of "tar" on corn leaves, but these spots are in fact brown lesions formed by the fungal pathogen Phyllachora maydis.
The Wnt signaling pathway: The foundation of cell growth, development, and potential therapeutics
The Wnt signaling pathway, a system present in living organisms, plays a pivotal role in cell growth, differentiation, and migration. It has a long history dating back to 1982, when the first Wnt gene, essential for cellular growth, was discovered. The pathway is initiated by Wnt ligands, a set of 19 glycoproteins that transmit signals through specific receptors and proteins, leading to...
Researchers reveal true crabs' epic ancient odyssey from sea to land and back again
Crabs are unique and continuously evolving animals, often moving their lifestyles out of marine environments for other environments to do so. The most popular food species can be fully marine (snow crab) or estuarine (Maryland blue crab, Dungeness crab). Some highly terrestrial species can climb trees if they are in higher levels, while others will die if they are fully immersed in water as...
Maps reveal biochar's potential for mitigating climate change
Biochar, a charcoal made from heating discarded organic materials such as crop residues, offers a path to lowering atmospheric carbon dioxide (CO2) at a time when climate scientists warn that urgent action is needed limit CO2 in the atmosphere.
Q&A: Birds of East Africa—their extraordinary diversity and changing behavior
101 Curious Tales of East African Birds is a new book that uses academic research to tell fascinating stories about the tropical birds of east Africa, from well-known species to rare ones. It also explores changing bird behavior in the region. Its author, Colin Beale, studies shifts in the distribution of birds and other animals. We asked him four questions.
The health and economic toll of gun violence in youth
Since 2020, firearms have been the number one cause of death among children and teens in the United States, surpassing even car accidents, according to the U.S. Centers for Disease Control and Prevention. In 2022, more than 4,500 young people died from firearm injuries.
Threatened sharks and rays caught off Cyprus
Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.
Mental health in the workplace is an ongoing challenge
In Quebec workplaces, psychological distress and psychotropic drug use have fallen back to prepandemic levels, but symptoms of depression, anxiety and burnout have become more widespread.
NASA's Curiosity rover clocks 4,000 days on Mars
Four thousand Martian days after setting its wheels in Gale Crater on Aug. 5, 2012, NASA's Curiosity rover remains busy conducting exciting science. The rover recently drilled its 39th sample, then dropped the pulverized rock into its belly for detailed analysis.
Avalanche of published academic articles could erode trust in science
A rapid rise in the number of academic articles being published could undermine public trust in science, warns an international study posted to the arXiv preprint server.
Black Americans from well-educated families continue to face educational barriers, finds study
While racial disparities in education have narrowed in the U.S., African American individuals from well-educated backgrounds still find it especially difficult to attain the same high level of education as their parents. A new study points to entrenched racial inequalities in parts of American society.
Paleobionics: A 450 million-year-old organism finds new life in softbotics
Researchers in the Department of Mechanical Engineering at Carnegie Mellon University, in collaboration with paleontologists from Spain and Poland, have used fossil evidence to engineer a soft robotic replica of pleurocystitid, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.
