An infamous pair of adult male orca whales in South Africa killed 17 sharks in "one sitting," according to marine biologists.The team at Marine Dynamics Conservation Trust has been tracking the two whales, named Port and Starboard, who are known to prey on several species of sharks.They found the orcas "repeatedly diving down in a small area for almost two hours before they departed offshore."Days later, they found the remains of 11 of the 17 killed sevengill sharks in Pearly Beach. Sevengill sharks can grow up to 10…

Henry Kirk always thought he would eventually leave his job as an engineering manager at Google and start his own company. But when he became one of the 12,000 employees let go by the tech giant in January, he decided his time had come—albeit in an earlier and unexpected fashion.Kirk and five others laid off from Google are now working on launching their own software design and development studio. He announced his ejection from Google and the new venture in a LinkedIn post that garnered more than 15,000 reactions. Kirk…

Pallas’s long-tongued bats have the fastest metabolism of any mammal, and feed on the nectar from flowers by hovering just outside of them like a hummingbird. Now, using high-speed infrared cameras, researchers at Dartmouth College have discovered that the whiskers on these bats help them expertly extract nectar from the blooms, sometimes as quickly as a half-second. The finding not only reveals a key piece of information about the bats, but also about how flora and fauna can evolve together.Pallas's long-tongued bats…

Space telescope images captured in infrared light reveal otherwise unseen details, as in this image of star-forming regions in the Orion Nebula. A recent study that relied on infrared data tracked frequent outbursts from baby stars as they gathered mass from surrounding disks of gas and dust. Credit: ESA/NASA/JPL-CaltechThe youngest stars often shine in bright bursts as they consume material from surrounding disks.Newborn stars “feed” at a furious rate and grow through surprisingly frequent feeding frenzies, a recent…

Whether you’re a DevOps, SRE, or just a data-driven individual, you’re probably addicted to dashboards and metrics. We look at our metrics to see how our system is doing, whether on the infrastructure, the application, or the business level. We trust our metrics to show us the status of our system and where it misbehaves. But do our metrics show us what really happened? You’d be surprised how often it’s not the case.In this post I will look into the math and mechanics behind metrics, some common misconceptions, what it…

According to new research, cat and dog owners could significantly reduce the environmental impact of their pets’ diets by feeding them dry food rather than wet food.Dog and cat owners could significantly reduce the environmental impact of their pets’ diets by feeding them dry food (consisting of kibble or biscuits) rather than wet food with higher water content. This is according to a study of Brazilian pets that will be published today (November 17) in the journal Scientific Reports. The findings highlight how pet owners…

James Webb has captured yet another breathtaking image of our universe. The new image, which NASA shared on Wednesday, is that of the dark cloud L1527, a newly birthed protostar that resides within the Taurus star-forming region of space. The clouds that make up the fiery hourglass shape in space are only visible with infrared light, NASA says. Because it’s only visible using infrared, the protostar is a perfect target for James Webb’s Near-Infrared Camera (NIRCam). NIRCam allows Webb to see special…

In the public sector, for example, just to call out a couple maybe. We've been working with the Open Data Institute to publish some of our data in a reusable format, raw data essentially, that scientists across the world can use, because we want to engage in that joint R&D practice. So there is data that we just share with the community, but we also care about data standards. So we're a board member of AgGateway, that is a consortium of I think what 200 or more food sector companies working on how do we actually…

This video still of the North Pacific Ocean shows phosphate nutrient concentrations at 500 meters below the ocean surface. The swirls represent small eddies transporting phosphate from the nutrient-rich equator (lighter colors), northward toward the nutrient-depleted subtropics (darker colors).
