Resource fishes—species targeted for human consumption—play a key role in reef ecosystems long before they end up on the dinner table. In Hawai'i, subsistence and recreational fishing of local resource fish represent more than half of the share of annual reef seafood consumption, while also playing a vital role in indigenous cultural life.
WSU Everett faculty members from the Edward R. Murrow College of Communication, the Voiland College of Engineering & Architecture and the Carson College of Business observed that several industries challenge Science, Technology, Engineering, and Math (STEM) education to incorporate business and communication experiences to prepare students for the workplace. These recommendations encouraged WSU...
Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study by the University of Bonn, Pennsylvania State University (U.S.) and Fudan University (China) has now somewhat closed this knowledge gap. It is the world's most detailed phylogenetic analysis ever conducted for asterids. The results of the...
One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes across Earth's landscapes, and modified biogeochemical cycling in such a way that Earth's climate became slightly colder.
Chemists report a new electrocatalyst that converts carbon dioxide and water into ethanol with very high energy efficiency, high selectivity for the desired final product and low cost.
The concentration of acetate increases particularly sharply at the site of an infection in the body. As reported in the journal Cell Metabolism by a team of researchers from the University of Basel and colleagues, acetate supports the function of certain immune cells and thus helps to eliminate pathogens safely and efficiently.
In a new study investigating human impacts on resource fish biomass on the Island of Hawai'i, researchers observed an alarming 45% decrease in fish biomass over a decade of surveys. The scientists proposed actionable solutions to mitigate future losses.
A new article examines fluted projectile points from southern Arabia, detailing production methods and technical aspects that indicate differences in function from the technology of the Americas, despite similarities in form. Findings from experimentation and comparative analysis suggest that highly-skilled, convergent technologies can have varying anthropological implications.
Taking vitamin D and calcium twice a day may reduce your chances of getting vertigo again, according to a new study.
Using data from NASA's InSight Lander on Mars, seismologists have made the first direct measurements of three subsurface boundaries from the crust to the core of the red planet.
Engineers conducted open road testing of three collision avoidance systems and demonstrated that a drivers' visual behavior in response to an alert generated from a collision avoidance system can be divided into one of four different behavioral categories: active gaze, self-conscious gaze, attentive gaze and ignored gaze.
NASA's Juno spacecraft -- orbiting and closely observing the planet Jupiter -- has unexpectedly discovered lightning in the planet's upper atmosphere, according to a multi-institutional study.
Catalysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, catalysts are involved in over 80 percent of all manufactured products.
A new study of captured mosquitoes in Los Angeles finds that West Nile infection is strongly associated with average temperature, and that temperatures above 73 degrees Fahrenheit are highly favorable for West Nile transmission. As climate change brings hotter weather to the region, it is likely that cooler, coastal neighborhoods will be pushed into the 'favorable' zone, accelerating transmission...
Even for people who carry the gene for early onset Alzheimer's disease, more years of education may slow the development of beta-amyloid plaques in the brain that are associated with the disease, according to a new study.
One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes across Earth's landscapes, and modified biogeochemical cycling in such a way that Earth's climate became slightly colder. A new study out today by Utah State University Assistant Professor of Watershed...
Space junk isn’t going away anytime soon—and neither are the problems it causes. We’re poised to see more satellite launches with every passing year, which means more pieces of rocketry and spacecraft getting loose and zipping around at over 22,000 mph. At those speeds, even an object just a few centimeters long could instantly destroy a satellite, and send even more debris...
Facebook's Instagram is officially launching its answer to the hit short video app TikTok — Instagram...
Using data from NASA's InSight Lander on Mars, Rice University seismologists have made the first direct measurements of three subsurface boundaries from the crust to the core of the red planet.
A new way to treat acid mine drainage (AMD) could help transform the environmental pollution problem into an important domestic source of the critical rare earth elements needed to produce technology ranging from smart phones to fighter jets, according to Penn State scientists.
The COVID-19 pandemic exposes weaknesses in the supply chain when countries go into lockdown. Some are small, such as the toilet paper shortages early on, that, while annoying, were eventually resolved. But what happens when the effects of the pandemic reach the food systems of countries highly reliant on food imports and income from abroad, and commerce slows to a halt?
The COVID-19 pandemic has caused much stress and uncertainty for students, parents, teachers and staff. "For students and the adults who care for them, the desire is so strong to have our lives return to normal, which also involves schooling," says Craig Sawchuk, Ph.D., a Mayo Clinic psychologist. "School is one of the most important places that we learn and grow intellectually, socially and...

SpaceX successfully flew a prototype of its next-generation Starship vehicle for the first time ever on Tuesday, a major step forward in the company’s quest to eventually send people to Mars. What happened: Around 8:00pm Eastern Time, from its testing site at Boca Chica, Texas, SpaceX flew the prototype about 500 feet into the air (the company has not yet stated what the exact altitude of the...
