Megachile pluto, Wallace's giant bee, is the world's largest, with a wingspan more than 2.5 inches. Though it should be easy enough to see, some had believed it was extinct because it hadn't been seen by western scientists since 1981.

In January, a search team set out to photograph Wallace's giant bee and successfully did so, declaring in a documentary they have "rediscovered" the species in the North Moluccas, an island group in Indonesia.

One of the problems that led to both opioid and medical marijuana overuse has been that the notion of pain is subjective. If someone claims they are in pain, a doctor has no way to know how much of it is real and how much is psychological.

A new test can identify biomarkers in the blood that can help objectively determine how severe a patient’s pain is. The blood test, the first of its kind, would allow physicians far more accuracy in treating pain—as well as a better long-term look at the patient’s medical future.

Croatian scientists have been engaged in scientific work at the European Organization for Nuclear Research (CERN) for close to 40 years. Croatian scientists worked on the SPS heavy-ion programme and in 1994, research groups from Split officially joined the CMS collaboration. One year later a research group from Zagreb joined the ALICE collaboration, working with Croatian industry partners to contribute to the construction of the experiments’ detectors.

Even if you are obsessed with "natural" things, the awesome power of physics can still help you make fun colors. It's all thanks to “structural color,” the ability of an object to generate color simply by the way light interacts with its geometric structure.

At the International Solid-State Circuits Conference last week, Rice University integrated circuit (IC) designers unveiled technology they say is 10 times more reliable than current methods of producing unclonable digital fingerprints for Internet of Things (IoT) devices.

Ribbon worm? Arrow worm? Since the discovery of its fossil over a century ago, paleontologists have speculated about what branch of evolution Amiskwia sagittiformis was on.

Charles Doolittle Walcott, who first described it, compared it to the a group of ocean-dwelling worms that are fierce predators, equipped with an array of spines on their head for grasping small prey - modern arrow worms (chaetognaths), but later scientists could not find evidence of the canonical grasping spines so they believed instead it might be a a ribbon worm, or its own distinct lineage only distantly related to anything that resembles it today.
