Cave Rescue: The Dangerous Diseases Lurking Underground

Doctors have placed the Thai cave boys in quarantine due to the infectious organisms they may have faced underground. So, which diseases could they have been exposed to, and how serious are they? It’s over. Against all odds, 12 boys and their football coach have dived, waded, climbed, and walked their way out of Tham Luang cave, a sprawling labyrinth of underground tunnels that has kept them prisoner for the last 17 days. They’ve been taken to the nearby Chiang Rai hospital to recover – but the reunion with their parents […]

How whale corpses feed ocean floors

Whales that end up on the beach make headlines. But those that sink to the bottom of the ocean make new homes for sea life. The brawn, blubber, and bone of these unlucky cetaceans—some 70,000 of which perish during harrowing seasonal migrations each year—nourish a vibrant, ­constantly evolving community of creatures. Opportunistic eaters can flourish on a decaying corpse for anywhere from a decade to a century. Marine ­biologists have discovered dozens of new critters in these deep-sea ecosystems since they first encountered one in 1987. For animals at the […]

Facebook faces £500,000 fine from UK data watchdog

https://www.bbc.com/news/technology-44785151 The UK’s data protection watchdog intends to fine Facebook £500,000 for data breaches – the maximum allowed. The Information Commissioner’s Office said Facebook had failed to ensure another company – Cambridge Analytica – had deleted users’ data. The ICO will also bring a criminal action against Cambridge Analytica’s defunct parent company SCL Elections. And it has raised concerns about political parties buying personal information from “data brokers”. Specifically it named one company used by the Labor Party, Emma’s Diary, which gives medical advice and free baby-themed products to parents. […]

We haven’t been giving Neanderthals enough credit

New evidence suggests they were skilled hunters. When Neanderthals are depicted in artistic reconstructions, they often have a spear in hand. Most archaeologists believe that Neanderthals were adept hunters, and we have found spears at Neanderthal sites. But our knowledge of how they used spears and how that compares with our own species has been inconclusive. Rather than using the spears for hunting, Neanderthals could have used them for self-defense or scavenging. But it turns out they didn’t. New research, published in Nature Ecology and Evolution, shows that Neanderthals did indeed use spears to hunt animals. The paper describes a collection of 120,000-year-old deer bones from the Neanderthal site of Neumark-Nord in Germany—two of which have perforations that clearly show impacts from a spear. These unusual artifacts prove that the earliest spears were effective hunting weapons. In a paper accompanying the new study, I discuss what the findings mean for our knowledge of the lives of the Neanderthals. Neanderthals evolved in part of Europe and Asia around 400,000 years ago, while our own species evolved in Africa. Scientists have traditionally thought that there were stark cultural and behavioral differences between Neanderthals and Homo sapiens, but recent discoveries have clarified that Neanderthals were more sophisticated than originally thought. For example, they cared for the vulnerable, buried their dead, and engaged in symbolic behaviors. It would therefore make sense that Neanderthals also hunted using weapons—even some chimpanzees do this today. Previous research […]

Archery on Horseback Becomes Popular Again-As a Sport

It’s not just a method of hunting or a strategy for battle anymore, and the athletes’ training regimen is intense. By Heather Brady PUBLISHED May 22, 2018 An ancient sport is making a comeback among younger generations. Mounted archery, a tradition with roots in empires like the Ottomans and the Mongols, has become popular again in Indonesia. While ancient warriors used the practice of shooting arrows from horseback for hunting and combat, its resurgence has become friendlier: Archers from different countries go through an intense training regimen to compete locally and internationally. The sport involves shooting arrows at a target while riding a horse. Successfully hitting a target with arrows is tricky when an athlete is standing or sitting on stable ground; when an archer is riding a horse, it requires even more balance, a high level of coordination, and a connection between the horse and archer. Mounted archery was used by many ancient cultures around the world, including Native Americans, European nomads, and Asian empires. It appears across cultural images and texts for several millennia and continued to be used until gunpowder and firearms were developed. As guns became popular, using a bow and arrow became less advantageous, and mounted archery was largely abandoned as a battlefield strategy. As communities in countries like Mongolia began honoring their predecessors and history by exploring ancient traditions, and after the sport appeared in mainstream pop culture through franchises like the Hunger Games, […]

Six Grand Ideas To Fight The End Of Antibiotics

Overuse of antibiotics has led them to becoming less and less effective to treat us when we’re sick – leaving scientists scrambling for a fix. Here are some of the best ideas to tackle one of the 21st Century’s biggest challenges. The world is nearing a moment when antibiotics no longer work to treat infections. We are severely over-using the antibiotics we have – and that system is causing bacteria to evolve and develop resistance to the drugs intended to kill them. Appropriately, the phenomenon is referred to as antibiotic […]

Could a hacker hijack your connected car?

By Emma WoollacottTechnology of Business reporter 6 October 2017 What if your self-driving car took on a mind of its own? As more carmakers adopt “over the air (OTA)” software updates for their increasingly connected and autonomous cars, is the risk of hacker hijack also increasing? Imagine jumping in your car but being taken somewhere you didn’t want to go – into oncoming traffic, say, or even over a cliff. That may seem like an extreme scenario, but the danger is real. Hackers showed two years ago that they could […]
