Study reveals long-term human impacts on reef fish
Career-readiness through cross-disciplinary project-based learning
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.
Study clarifies kinship of important plant group
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...
Acetate regulates immune cells for a precisely orchestrated immune defense
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...
An iconic Native American stone tool technology discovered in Arabia
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.

Ammonia sparks unexpected, exotic lightning on Jupiter
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.

Researchers discover new electrocatalyst for turning carbon dioxide into liquid fuel
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.
Herbivores, not predators, most at risk of extinction
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.
How to cast a wider net for tracking space junk
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...
Instagram launches TikTok copycat, which it is calling Reels
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...
Rice researchers use InSight for deep Mars measurements
Facebook's Instagram is officially launching its answer to the hit short video app TikTok — Instagram...
New acid mine drainage treatment turns waste into valuable critical minerals
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.
Researchers examine food supply chain resiliency in the Pacific during COVID-19 pandemic
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.
Head back to school with '4 Be's' for mental health
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?
SpaceX flew a prototype of its Starship vehicle for the first time
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...
At least five dead in US as downgraded Isaias reaches Canada
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...
Bay Area coastal flooding triggers regionwide commute disruptions
Tropical storm Isaias left at least five people dead as it pounded the US eastern seaboard with driving winds and heavy rain, leaving millions without power, before moving across Canada on Wednesday.
In ancient Arabia, some tools were created to show off skills
For decades, the low-lying neighborhoods along the San Francisco Bay have experienced coastal flooding and the subsequent traffic disruptions. But a new computational model by Stanford researchers reveals that, due to the nature of road networks in the region, commuters living outside the areas of flooding may experience some of the largest commute delays.
New study reveals lower energy limit for life on Earth
People living in southern Arabia some 8,000 years ago created intricate stone weapons that were not just useful, but designed to "show off" their tool-making skills, a new study suggests.
Plate tectonics goes global
An international team of researchers led by Queen Mary University of London have discovered that microorganisms buried in sediment beneath the seafloor can survive on less energy than was previously known to support life. The study has implications for understanding the limit of life on Earth and the potential for life elsewhere.
Today, the entire globe is broken up into tectonic plates that are shifting past each other, causing the continents to drift slowly but steadily. But this has not always been the case.
