What do bones and 3-D-printed buildings have in common? They both have columns and beams on the inside that determine how long they last.

In 2019, researchers at the California Academy of Sciences added 71 new plant and animal species to our family tree, enriching our understanding of Earth's complex web of life and strengthening our ability to make informed conservation decisions. The new species include 17 fish, 15 geckos, eight flowering plants, six sea slugs, five arachnids, four eels, three ants, three skinks, two skates, two...
Protocells—artificial cells—that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers.
Recycling biotechnology byproducts can enhance soil health while reducing carbon emissions and maintaining crop yields.
Going pro early may be a no-brainer for exceptional, young basketball stars like former Duke freshman and 2019 NBA draft first-pick Zion Williamson. But a study in the "International Journal of Sport Finance" proposes a new salary structure that might entice most other college players considering the NBA to graduate before trying their hand at going pro.
NASA's Terra satellite captured an image of Tropical Cyclone Ambali and the visible image showed that the storm was rapidly intensifying.
Old habits are hard to break. A McGill-led study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy. The study was...
Shortly after NASA's OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission's science team revealed that the asteroid could be active, or consistently discharging particles into space. The ongoing examination of Bennu—and its sample that will eventually be returned to Earth—could potentially shed light on why this intriguing phenomenon is occurring.
For many young college students, the first years are a time of wonder and excitement and early steps toward long-term goals. These years, for some students, are equally fraught with anxiety, as the realities of rigorous curricula set in alongside feelings of unpreparedness and impostor syndrome. In the STEM fields, this results in roughly 50% of first-year majors leaving their original course of...
Tropical species are six times more sensitive to forests being broken up for logging or farming than temperate species, says new research.
A joint research team led by Mao Fangyuan from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and Meng Jin from the American Museum of Natural History reported a new symmetrodont, Origolestes lii, a stem therian mammal from the Early Cretaceous Jehol Biota, in China's Liaoning Province.
SpaceX launched a 3-ton shipment to the International Space Station on Thursday, including "mighty mice" for a muscle study, a robot sensitive to astronauts' emotions and a miniature version of a brewery's malt house.
A random conversation between two Cornell researchers at a child's birthday party led to a collaboration and new understanding of how bacteria resist toxins, which may lead to new tools in the fight against harmful infections.
Move over Godzilla vs. King Kong—this is the crossover event you've been waiting for. Well, at least if you're a condensed matter physicist. Harvard University researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties. Not entirely sure what that means? Don't worry, we'll walk you through it. All you need to know...
The creation of photoelectrons through ionisation is one of the most fundamental processes in the interaction between light and matter. Yet, deep questions remain about just how photons transfer their linear momentum to electrons. With the first sub-femtosecond study of the linear photon momentum transfer during an ionisation process, ETH physicists provide now unprecedented insight into the birth...
A team of Florida State University researchers studying new methods to remove toxic heavy metals from biosolids—the solid waste left over after sewage treatment—found the key is a brief spin through a microwave.
NASA's Aqua satellite captured an image of Tropical cyclone 02S and the visible image showed that the storm was getting better organized.
A cluster of industrial chemicals known by the shorthand term "PFAS" has infiltrated the far reaches of our planet with significance that scientists are only beginning to understand.
NASA-NOAA's Suomi NPP satellite passed over the Arabian Sea and captured a visible image of Tropical Storm 06A, now renamed Tropical Storm Pawan.
According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. AWI researchers have now, for the first time, tested the concept using a complex climate model and published their findings in the journal Earth's Future. Their verdict is...
NASA provided analyses of Typhoon Kammuri's heavy rainfall on its track through the Northwestern Pacific Ocean using the Global Precipitation Measurement mission or GPM core satellite.
Flowering plants are characterized by an astonishing diversity of flowers of different shapes and sizes. This diversity has arisen in adaptation to selection imposed by different pollinators including, among others, bees, flies, butterflies, hummingbirds, bats or rodents. Although several studies have documented that pollinators can impose strong selection pressures on flowers, our understanding...
Canadians spend a lot of money around this time of year, on gifts, food, entertainment and travel. In its annual study of holiday season spending habits, the accounting firm PwC estimates that the average Canadian consumer will drop close to $1,600 in 2019.
Potatoes are important. They rank fourth among the world's staple crops. In the United States, they are grown commercially in 30 states and valued at $4 billion annually. Potatoes are also susceptible to 160 different fungal, bacterial, and viral diseases, such as blackleg and soft rot diseases, which are caused by the bacterium Dickeya dianthicola.
You cannot make glue out of a ham sandwich—but you may be able to use the components of that food to create a strong adhesive.
