The gentle curve of a beam. The particular shape of a clay brick. The sharp angles of a series of trusses. You might view these elements of buildings, bridges, and structures as part of the aesthetic and artistic design, or maybe you have overlooked them completely. But for London-based structural engineer Roma Agrawal, these visual charms play an important role not only in the beauty of a building, but in the physics that keep a structure from tumbling down. Agrawal reveals the hidden...

Biohybrid Robots, Neanderthal Art. Feb 23, 2018, Part 2

2/23/2018
More
A group of engineers are building softer, squishier robots—ones you might knowingly invite into your home to hang out. Instead of sporting bodies of rigid plastic and metal, biohybrid robots often consist of 3D-printed scaffolds laced with lab-grown muscles, sourced from the cells of mice, insects, and even sea slugs. Some "bio-bots" can even heal themselves after an injury, and get back to work. A roundup of engineers talk about the growing fleet of biohybrid robots. Plus, since the first...

2/16/2018
More
While oohing and ahhing at the powerful leaps and nimble spins on the ice at the Olympics, you may not realize you’re watching physics in action. Each jump requires a careful balance of matching the time in air to the speed and number of rotations. From spray can to ocean spray, it's time to talk about aerosols. They do play a role in climate change, but not the one you might think. There's a new urban air polluter on the block. Volatile organic compounds like wall paints and cleaning...

Venomous Or Poisonous, Crayfish Clones, Immune System Cancer Injection. Feb 9, 2018, Part 2

2/9/2018
More
Do you know the difference between a poisonous creature and a venomous one? One distinction is that poisons are often ingested or absorbed by the skin, while venoms have to be injected through a wound. Mandë Holford tells us more about her research studying these dangerous creatures. 25 years ago, all-female crayfish species originated from a hobbyist tank in Germany. In the wild, the crustacean developed a mutation that allowed it to pick up a third set of chromosomes and reproduce...

Dinosaurs existed all over the world—fossils have been found on every continent. Africa is no exception, but far fewer fossils have been found there from the late Cretaceous era—the period before the dinosaurs went extinct. But a new discovery in Egypt could provide clues about the evolution of dinosaurs in Africa. Click here to learn more. Last weekend, an Australian researcher pointed out on Twitter that a “heat map” of popular running locations released by the fitness app Strava could...
