Scientists in the UK and Sweden believe theyve come across an unprecedented advance in Alzheimers disease research: A method of developing new drugs that can target the roots of the fatal disease in a way t adidas samba hat previous attempts couldnt. But while the latest published work is genuinely intriguing, outside experts are worried that the researchers claims to the public are too grandiose. Alzheimers disease is the most common form of dementia, affecting 5.7 million Americans, according to the Alzheimers Association. Theres still a lot we dont understand about the exact sequence of events that leads to Alzheimers, but were fairly sure that a brain protein known as amyloid beta plays a pivotal role. In its normal state, amyloid beta seems to play some unknown but important role in the brain some scientists believe it might protect us from infections . But when amyloid beta molecules dont fold the right way, they can clump together and damage the brain. By the time symptoms like memory loss and confusion sho dunk panda w up, a persons brain is littered with fiber-like plaques made of yeezy slide amyloid beta. The accumulation of another protein called tau鈥攌nown as tangles鈥攎ight damage the brain and cause the symptoms of Alzheimers too, but the flooding of amyloid beta is thought to show up first and drive the progression of the disease. Scientists have tried to create drugs that delay or prevent Alzheimers by clearing away these plaques, but the clinical trials of these treatments have abysmally failed Gpjv Birdman聽Upsets Boyhood,聽Winning Top Honors At PGA Awards
If we burned all the coal, oil and gas thats left in the ground, wed melt Antarctica and global sea levels would rise as much as 60 meters 200 feet over the next ten thousand years. Coastal cities from New York to Shanghai would wind up deep underwater. Thats t skechers he disturbing conclusion of a new modeling paper that appears today in Science Advances. It sounds pretty pessimistic, but in a world where the basic premise of climate change is under constant attack, scientists have begun turning to extreme scenarios to make their point crystal clear. The new study is the first to model the effects of unfettered fossil fuel burning across the entire Antarctic ice sheet. Our study shows that if we dont leave most of the carbon in the ground, we are going to melt most of the ice on this planet, lead study author Ken Caldeira of the Carnegie Institution told Gizmodo. Burn It All There are roughly 10,000 billion metric tons Gt of carbon-rich fuel sitting beneath our feet, according reebok c85 club to a recent report by the Intergovernmental Panel on Climate Change IPCC . Human activities have already caused the release of some 555 Gt of carbon dioxide since the beginning of the industrial rev airmax plus olution. If wed like to cap ourselves at 2潞C of global warming over the long term and avoid catastrophic climate change, weve got to limit our future emissions to another 600 Gt of carbon or less, says the IPCC. But what if that doesnt happen In their paper, the researchers used an ice-sheet evolution mod
