The sun rises over the South African bush as scientists laden with backpacks climb a hillside. Jonah Choiniere and his team from Johannesburg's Witwatersrand University had tracked the reptile from another age for three years. The search brought them to a stretch of farmland in the central town of Rosendal, where they are surrounded by cattle and impalas.
Promises by Brazil´s far-right presidential candidate Jair Bolsonaro and his entourage bode badly for the future of the Amazon -- called the "lungs of the planet" -- if he wins, environmentalists warn. "If he's elected, that will be the beginning of the end for the Amazon," his leftist rival in Sunday´s run-off, Fernando Haddad, said last week. Bolsonaro has also several times evoked studies to build hydroelectric power stations in the Amazon, which implies the construction of massive dams that would greatly impact water courses and require communities to be moved.
A San Francisco judge on Monday upheld a jury verdict that found Monsanto liable for not warning a groundskeeper that its weed killer product Roundup might cause cancer, but slashed the damages award. Judge Suzanne Bolanos denied Monsanto's request for a new trial but cut the $289 million damages award to $78 million to comply with the law regarding how punitive damages awards must be calculated. Jurors in August unanimously found that Monsanto acted with "malice" and that its weed killers Roundup and the professional grade version RangerPro contributed "substantially" to Dewayne Johnson's terminal illness.
SEATTLE (AP) — Young activists who are suing the U.S. government in a high-profile climate change lawsuit say the case poses important constitutional questions that should be fully evaluated at trial next week.
Once a rocket leaves the launch pad, all eyes turn skyward, but the technology that keeps launch sites working at their peak efficiency is pretty darn interesting in its own right. In a new video posted to YouTube, NASA shows off its insanely powerful water system that will keep things cool during the upcoming launches of the Boeing-built Space Launch System.
What you're seeing is roughly 450,000 gallons of water being pumped out in about a minute. It's called the Ignition Overpressure Protection and Sound Suppression system, and NASA uses it to keep the launch pad at a manageable temperature even as its being blasted by a rocket.
As NASA notes in the video's description, the test was performed at Launch Pad 39B at Kennedy Space Center. The water was pushed around 100 feet in the air before spilling back into a large trench where it travels back to holding ponds.
In this case, the water spewed upward because the rest of the hardware isn't fully connected yet. When the launcher is in place, the water will actually flow through a network of pipes and nozzles rather than spewing out like a geyser. Along with helping to dissipate the heat generated during the rocket firing, the water also helps absorb some of the intense noise that the rocket will generate.
NASA says that this latest test is yet another big step towards the eventual launch of the Space Launch System on its first major test, Exploration Mission-1, which is expected to take place sometime around mid-2020. That's still a long way off, but getting into space takes time, especially when a new launch vehicle is part of the deal.
Thirty-five Nobel and top mathematics prize winners have warned British Prime Minister Theresa May and European Commission chief Jean-Claude Juncker that scientific research will suffer a serious setback without a good Brexit deal. The 29 Nobel Prize winners in science and six recipients of the Fields Medal -- one of the most prestigious awards in maths -- said open European borders had helped the continent make up ground lost to US researchers in the wake of World War II.
To say that the 2016 presidential election had a profound impact on the American psyche might be an understatement. In fact, new research suggests that for many, the experience was actually traumatic. In a survey of roughly 800 college students, 25 percent reported such high levels of stress after the election that researchers likened it to symptoms of post-traumatic stress disorder, according to a new study published in the Journal of American College Health. Throughout the election, researchers noticed some pretty strong reactions in young adults. But the day after the election, lead researcher Melissa Hagan taught two classes where she saw that students were visibly upset — some were even crying.

Hagan and her team administered a psychological assessment called the Impact of Event Scale, which is a standard quick measure to gauge how a person responded to trauma, and they tailored the questions to the presidential election. They found that some college students were reporting that they were impacted by the election “in such a way that it might lead to diagnosable post-traumatic stress disorder,” Hagan said in a statement. Some common symptoms of that kind of stress are chronic fatigue, physical illness, stomach or chest pain, and feeling overwhelmed. Results of the survey found that certain groups scored higher on the assessment than others. For example, Black and Hispanic students reported higher levels of stress than their white peers. Women scored about 45 percent higher than men. And Democrats scored two and a half times higher on the assessment. Non-Christians also reported feeling strongly affected by the election results. However Hagan said it's important to note that the presidential election itself does not technically constitute a traumatic event.

That said, media coverage of the new administration's potential policies, some which have already been enacted, were perceived as life-threatening to some Americans. Moreover, many didn’t believe Donald Trump would be elected — especially not after the Access Hollywood tape was released, which might have been triggering for women and men who are survivors of sexual assault. Psychotherapist and author Jonathan Alpert, who is unaffiliated with the study, said the study’s results do not come as a shock to him. “It wasn’t politics as usual," Alpert, who wasn't involved in the new study, said in an interview.

It's possible that the shared outrage of college students could reinforce their levels of stress, Alpert said. "It’s almost like a contagion effect. You could almost catch stress from one another — like empathy," he said. Barbara Nosal, Chief Clinical Officer at the mental health facility Newport Academy who is also unaffiliated with the study, said in an interview that the degree of impact also might have to do with where young adults are in their lives. The competitive college environment, technology, and an undefined sense of independence already affects young adult development — plus, the election was an additional stressor.

Nosal said the depth of a reaction is also dependent on the individual person or their most salient demographic, not necessarily the stressor itself. “Maybe a comment or something that occurs afterwards in their personal life brings the trauma up — plus ongoing discussions in the media may also trigger a traumatic response," Nosal said. And while the survey couldn’t reveal any long-term impacts since the assessment was only administered once — if these symptoms are left unresolved, Nosal said anxiety disorders and depression may follow. As to whether or not the clinical levels of stress vary based on the overarching political ideology of the school, Hagan thinks "it may be that symptoms are higher in states more 'left-leaning,'" but more research would have to be done to know for sure.

Mexico, Oct. 22 (Notimex).- The National Autonomous University of Mexico (UNAM, for its acronym in Spanish) has launched an electronic platform to promote and publicize its products and services in the academic world. In this platform, interested parties can contract a service or consult a project of researchers from more than 70 entities of the university, as well as search by keyword or through different sections. Clara Lopez Guzman, Director of Special Projects of the Coordination of Innovation and Development, explained that it is COGNOS-UNAM www.cognos.unam.mx, an electronic catalog with access to developments developed in the maximum house of studies. That is, technical and clinical services, as well as training, and adds laboratories, technologies and publications that may be susceptible to transfer, especially patents and software, which contribute to the country's development. "Through a simple search engine, those interested in hiring a service or consult some knowledge of our researchers and their projects, can do a search by keyword or through different sections," she said. COGNOS exists since 2015, but had worked only internally. Now, within the framework of the first decade of the existence of the Coordination of Innovation and Development (CID, for its acronym in Spanish), this platform opens up to the productive, public, private and social sectors. Starting this month, the CID begins its relationship with industry chambers and industries so that they know about it. The system puts the user in contact with a linker, who will attend directly, and then personalized, the initial request that was made online. This network has periodic meetings, workshops and courses where they receive training to meet a profile that allows them to sign agreements, provide services and make economic proposals and advice on how to charge and bid. Lopez Guzman indicated that the linkers have the task of putting in contact and encouraging, where appropriate, new lines of research, and perhaps the creation of a patent, and a company with that patent. "That would be a great success story, where COGNOS would be the seed," she concluded. NTX/ERM/DAP/BBF
Mice brought to a remote South Atlantic island by sailors in the 19th century are threatening seabirds including the critically endangered Tristan albatross, a British charity said on Monday. The Royal Society for the Protection of Birds said the rodents have proliferated on uninhabited Gough Island, part of a British overseas territory, and are killing two million birds every year. "We knew there were large numbers of chicks and eggs being beaten each year but the actual number being taken by the mice is just staggering," Alex Bond, a researcher from the Natural History Museum in London, said in a statement released by the RSPB.
MINNEAPOLIS (AP) — Earl Bakken, an electronics repairman who created the first wearable external pacemaker and co-founded one of the world's largest medical device companies, Medtronic, has died. He was 94.
Lysergic acid diethylamide was labelled a "problem child" by the man who discovered its hallucinogenic properties in 1943: as it turns 75, the drug known as LSD may now be changing its image. The late Swiss chemist Albert Hofmann famously learned of LSD's psychedelic effects when he inadvertently took a small dose while doing lab work for pharmaceutical company Sandoz. The book, in which Hofmann sought to reassert LSD's potential medical benefits, is featured in an exhibition at the Swiss National Library in the capital, Bern, to mark 75 years since the discovery.
Close to the seafront in Lebanon's Tripoli, giant curves of concrete stand testimony to dreams before the civil war, etchings of an exhibition park never finished but already cracking. This month, a rare exhibition is being held at the site designed by legendary Brazilian architect Oscar Niemeyer in a desperate call to save it from ruin. Inside the vast grey grounds of the Tripoli International Fair in northern Lebanon, a palm tree throws its dark silhouette onto a giant concrete dome.
