The Strange Saga of Jack Teixeira Reveals New Security Challenges

Moments before his arrest by armed FBI agents on Thursday, a helicopter from a local news station caught footage of 21-year-old Jack Teixeira reading a book on the sun-splashed back porch of his house in North Dighton, Mass. In his front yard, meanwhile, FBI agents in camouflage tactical gear were climbing out of an armored vehicle, tightening the straps of their bullet-proof vests and gripping long guns. The dramatic scene playing out in a sleepy, riverside exurb underscored the peculiarity of a case that exposed military documents, complicated relations with U.S. allies, and triggered national embarrassment. Intelligence leaks of this magnitude in the past have been the result of an alienated whistle-blower, double agent or successful spy operation. Now arguably the most damaging disclosure of U.S. government documents in a decade may have stemmed from the hubris of a junior enlisted member in the Massachusetts Air National Guard who shared them in a small online chat group called Thug Shaker Central.

        Oppenheimer’s brief advance into astrophysics began with a 1938 paper about neutron stars, which continued in a 1939 installment that further incorporated the principles of Einstein’s general theory of relativity. He then published a third paper on black holes on September 1st, 1939—but at the time, it was scarcely noticed because this was the very day Germany invaded Poland, launching World War II. Oppenheimer never wrote on the topic again.
        Even if it hadn’t been overshadowed by war, Oppenheimer’s work on neutron stars and black holes “was not understood to be terribly significant at the time,” says Cathryn Carson, a historian of science at the University of California, Berkeley.
        Each paper was written with a different member of the swarm of graduate students that Oppenheimer carefully cultivated. These protégés facilitated his ability to jump between research topics—and ultimately, helped him develop some of his most important contributions to physics.
        Oppenheimer’s climactic third paper, written with his student Hartland Snyder, explores the implications of general relativity on the universe’s most massive stars. Although the physicists needed to include some assumptions to simplify the question, they determined that a large enough star would gravitationally collapse indefinitely—and within a finite amount of time, meaning that the objects we now know as black holes could exist.

'A Spiraling Loopof Feedback':

Worst-Case Scenario for Amazon Rainforest 


     A paper to be published in the Journal Science on January 27 has found that humans have degraded more than one-third of the remaining trees in the Amazon rainforest. This degradation could eventually lead to "a spiraling loop of feedbacks," Jos Barlow, a professor of conservation science at Lancaster University in the U.K. and co-author of the paper, told Newsweek.

    Up to 38 percent of the remaining Amazon has been affected by human actions, researchers from Brazil's University of Campinas (Unicamp), the Amazon Environmental Research Institute (IPAM), National Institute for Space Research (INPE), and Lancaster University found.  

   The degradation of this areaequivalent to 5.5 times the size of the state of Californiareleases carbon emissions equivalent to or greater than those from deforestation. 

   The Amazon contributes 16 percent of all the land-based photosynthesis in the world, and strongly regulates global carbon and water cycles, sucking in carbon dioxide and producing oxygen. Additionally, despite only covering around 0.5 percent of the Earth's surface, the Amazon is home to over 10 percent of all named plant and vertebrate species on Earth.

    "Healthy rainforests provide amazing habitat for biodiversitythis is what the Amazon is most famous for," Sally Thompson, an ecohydrologist at The University of Western Australia, told Newsweek. "They usually support clean water in rivers, make it rain, and cool the surrounding area. You can hunt, harvest timber or foods sustainably from healthy and wellmanaged forests. And a healthy forest can often recover from disturbance. Degraded forests aren't as good at doing any of those things, and often they struggle to recover from disturbance."

    Deforestation involves a loss of the forest canopy and a change in land use (e.g., from forest to agriculture or urban land use), while degradation is a process affecting the remaining forests. Degradation essentially means that there is still forest in place but it is not as healthy or as good at providing benefits for the environment or for people.

Quantum breakthrough could revolutionise computing


    Computer scientists have been trying to make an effective quantum computer for more than 20 years. Firms such as Google, IBM and Microsoft have developed simple machines. But, according to Prof. Winfried Hensinger, who led the research at Sussex University, the new development paves the way for systems that can solve complex real world problems that the best computers we have today are incapable of.

    "Right now we have quantum computers with very simple microchips,"he said. "What we have achieved here is the ability to realise extremely powerful quantum computers capable of solving some of the most important problems for industries and society."

    Currently, computers solve problems in a simple linear way, one calculation at a time. In the quantum realm, particles can be in two places at the same time and researchers want to harness this property to develop computers that can do multiple calculations all at the same time.

    Quantum particles can also be millions of miles apart and be strangely connected, mirroring each other's actions instantaneously. Again, that could also be used to develop much more powerful computers.

    One stumbling block has been the need to transfer quantum information between chips quickly and reliably: the information degrades, and errors are introduced.

    But Prof. Hensinger's team has made a breakthrough, published in the journal Nature Communications, which may have overcome that obstacle.

     The team developed a system able to transport information from one chip to another with a reliability of 99.999993% at record speeds. That, say the researchers, shows that in principle chips could be slotted together to make a more powerful quantum computer.
