A famous viral video about the DARPA Robotics Challenge shows all sorts of humanoid robots clumsily falling down. Bipedal movement is rather unstable, which is not only a problem for a robot trying to complete its task, but also because falling can damage a very expensive piece of machinery. Roboticists across the globe are tackling

Phages that die during bacterial invasion help other viruses defeat the microbes’ immune responses. Bacteria can fend off viral infections by chopping up their DNA with their CRISPR-based immune system, but sufficient numbers of phages can overwhelm microbes’ defenses. In two papers published in Cell today (July 19), scientists report that part of phages’ strategy appears to

The mouth of today’s crocodilians inspires fear and awe, with their wide gape and the greatest known bite force in the vertebrate animal kingdom. However, this apex predator of today and its modus of attack (its mouth) had humble beginnings. The very earliest crocodilians were very different to the beasts we know well today, they

A new study in the Journal of the National Cancer Institute suggests that CT scans, commonly used in medical imaging, may increase the risk of brain tumors. The use of computed tomography (CT) scans has increased dramatically over the last two decades. CT scans greatly improve diagnostic capabilities (which improve clinical outcomes) but they deliver higher radiation

Viking Orion, the newest Viking Ocean Cruise ship, made its debut in Italy on June 14, revealing a unique high-tech feature: a planetarium at sea. The ship is named after the constellation Orion (the hunter) and NASA’s Orion spacecraft, the first crewed capsule designed to carry astronauts beyond low Earth orbit. The ship’s name also

A research team led by The Australian National University (ANU) has found the first proof that Antarctica is not isolated from the rest of the Earth, with the discovery that foreign kelp had drifted 20,000 kilometres before surfing to the continent’s icy shores. Scientists had previously thought that Antarctic plants and animals were distinct from

Compared to other drugs, therapeutics given breakthrough status receive FDA approval on the basis of weaker trial evidence, a study finds. The US Food and Drug Administration’s “breakthrough therapy” designation has helped expedite the development and approval of more than 45 therapeutics in the last 5 years. But a study published in JAMA today (July 17) suggests
