'Quark Fusion' Produces Eight Times More Energy Than Nuclear Fusion (futurism.com) 173

walterbyrd shares a report from Futurism: This new source of energy, according to researchers Marek Karliner and Jonathan Rosner, comes from the fusion of subatomic particles known as quarks. These particles are usually produced as a result of colliding atoms that move at high speeds within the Large Hadron Collider (LHC), where these component parts split from their parent atoms. It doesn't stop there, however, as these disassociated quarks also tend to collide with one another and fuse into particles called baryons. It is this fusion of quarks that Karliner and Rosner focused on, as they found that this fusion is capable of producing energy even greater than what's produced in hydrogen fusion. In particular, they studied how fused quarks configure into what's called a doubly-charmed baryon. Fusing quarks require 130 MeV to become doubly-charmed baryons, which, in turn, releases energy that's 12 MeV more energy. Turning their calculations to heavier bottom quarks, which need 230 MeV to fuse, they found that a resulting baryon could produce approximately 138 MeV of net energy -- about eight times more than what hydrogen fusion releases. The new study has been published in the journal Nature.

New Technology Should Be Neither Feared Nor Trusted (bloomberg.com) 61

An anonymous reader quotes a report from Bloomberg: How should we think about new and future technologies? The two main stances seem to be extreme optimism and extreme pessimism. A better approach would be careful planning and management. Optimists tend to overlook the fact that the technological successes of the past required a lot of social engineering before their benefits became widely shared. Countries like Maoist China and North Korea implemented perverse economic systems that withheld the bounty of modern technology from most of their citizens. And poor countries didn't really begin to beat poverty until decades after colonialism ended. Pessimists, meanwhile, often assume that new technologies can be stopped in their tracks by act of popular will. They probably can't. Even the most impoverished, repressive regimes of the 20th century adopted new technologies, and often suffered their worst consequences. Scientific research and invention, meanwhile, can be forbidden in one country or another, but probably not at the global level: Someone, somewhere, will study even the scariest ideas.

A better approach, then, is technology management. We should be as realistic as we can about each innovation's potential benefits and dangers. And instead of thinking about how to suppress new technologies, we should think about how to regulate them and channel them toward broad social benefit. Emerging technologies like genetic engineering and artificial intelligence are at our doorstep, and there is no putting the genie back in the bottle. But letting them develop haphazardly entails large risks. Instead, government and industry need to be funding proactive efforts to bring them into widespread, well-regulated use. In the end, technology is what we choose to make of it.

The US Is Now the Only Country In the World To Reject the Paris Climate Deal 719

An anonymous reader quotes a report from The Verge: Today, Syria announced that it would sign the Paris climate agreement -- a landmark deal that commits almost 200 countries to reducing greenhouse gas emissions to fight global warming. With Nicaragua also joining the deal last month, the United States is now the only country in the world that opposes it. In June, President Donald Trump announced that the U.S. will withdraw from the Paris climate accord, unless it is renegotiated to be "fair" to the United States. But other countries in the deal, such as France, Germany, and Italy, said that's not possible. The Trump administration is also taking steps to roll back regulations passed under former President Barack Obama to achieve the emissions reduction goals set under the Paris deal. The U.S. is the second largest emitter of heat-trapping greenhouse gases in the world after China. "With Syria's decision, the relentless commitment of the global community to deliver on Paris is more evident than ever," Paula Caballero, director of the climate change program at the World Resources Institute, told the Times. "The U.S.'s stark isolation should give Trump reason to reconsider his ill-advised announcement and join the rest of the world in tackling climate change."

Florida Attempts the Largest Hydraulic Restoration Project In the World To Save the Everglades (vice.com) 98

New submitter ar2286 shares a report from Motherboard: Florida is defined by its water -- the water flowing around it, through it, increasingly over it. But throughout the twentieth century, its major arteries of fresh water, which flowed from the Kissimmee River south of Orlando to Lake Okeechobee and down to the swampy Everglades, were permanently rerouted by the federal government and landowners to stop flooding, and make room for agriculture and housing in the southern part of the state. Now the state is working with the Army Corps of Engineers -- the government agency partly responsible for rerouting and draining water to begin with -- and the South Florida Water Management District to attempt the largest hydraulic restoration project in the world. And while some say the effort has turned Florida into a battleground, pitting sugar farmers against legislators and environmentalists, others are hoping this will finally right certain man-made wrongs and restore some balance to the state. If the government is able to fully fund the plan, and should dozens of contractors and state forces successfully carry it out, it could permanently change Florida. And set a precedent for inevitable restoration projects around the world, which are becoming increasingly crucial as climate change manifests in stronger storms and sea level rise. The state is embarking on such a massive restoration project because the aging levees and control gates surrounding Lake Okeechobee are at risk of failing during large storms and/or heavy rainfall. "The more rainwater that increases in Lake Okeechobee, the more pressure is on the lake, and that pressure can continue to build up and build up and build up and one day the levee can go," said Tammy Jackson-Moore, a Belle Glade resident who co-founded Guardians of the Glades, a nonprofit focused on community advocacy. "And we're talking about wiping out entire communities here." The rerouting has allowed for bursts of economic growth, but it does have its consequences. "The Everglades, the largest swath of subtropical wilderness in the country, is now half of its size circa 1920, and the ecosystem has deteriorated, losing wildlife and native flora," reports Motherboard. "Without a natural place to flow, stagnant water pushes toxic algae blooms into the rivers, and turns pristine ocean into sludgy waste."
