SOPA Images/Getty Images The European Union’s antitrust regulators have opened an investigation into Amazon. The goal is to explore whether the e-commerce giant breached the EU’s competition rules with its use of data from independent retailers. Commissioner Margrethe Vestager, who is in charge of the EU’s competition policy, said European customers shop online for the selection and pricing.”We need to ensure that large online platforms don’t eliminate these benefits through anti-competitive behaviour. I have therefore decided to take a very close look at Amazon’s business practices and its dual role as marketplace and retailer, to assess its compliance with EU competition rules,” Vestager said Wednesday in a statement. In an email, an Amazon representative said the company will cooperate fully with the European Commission and continue working to support businesses of all sizes. 14 Photos The EU announced the investigation on the heels of Prime Day, the company’s biggest sale. While many people shopped, Prime Day also brought out a wave of anti-Amazon protests and activism over everything from climate issues to the company’s ties to US Immigration and Customs Enforcement.Amazon and other tech giants like Facebook and Google have also come under scrutiny from Congress about potential antitrust issues. 0 null 7:35 Share your voice Smart displays let Amazon, Facebook, Google show you answers to your questions
Prime minister Sheikh Hasina is addressing her valedictory speech in the 21st (budget) session of the current parliament on 12 July. Photo: PIDPrime minister Sheikh Hasina on Wednesday said the security and stability of Bangladesh could be hampered if the displaced Rohingya people cannot be repatriated soon, reports UNB.”If we can’t send them back soon, there’s an apprehension that our security and stability will be at stake,” she told parliament while replying to a tabled question from Awami League MP Nur Mohammad (Kishoreganj-2).The prime minister said, “It’s very tough for us to arrange food, clothes and accommodation for over 1.1 million Myanmar nationals for an indefinite time.”This is why the government has been making diplomatic efforts to find out a permanent solution since the very beginning of the crisis for sending the forcibly-displaced Rohingyas back to their homeland, she said.Sheikh Hasina said the displaced people, deprived of basic rights by the Myanmar authorities, are naturally suffering from dissatisfaction.Noting that any repatriation process is a very complicated and lengthy process, she said Bangladesh and the international community are exerting pressure on Myanmar to create a congenial environment in Rakhine state.Unfortunately, she said, it is true there has been no visible progress in the situation due to a rigid stance of Myanmar government.Besides, Myanmar is involved in carrying out propaganda in the international arena that the Rohingya repatriation is being delayed for the noncooperation of Bangladesh, she added.The prime minister said Bangladesh repeatedly raised voice in different fora that Myanmar is responsible for taking back its all the displaced people, and Myanmar will have to take the initiative in this regard.She said Bangladesh and Myanmar signed a total of three bilateral agreements. The repatriation process would be completed within two years according to an agreement out of three. “But the Myanmar government has delayed the process by creating in many ways.”In reply to a question from treasury bench member M Abdul Latif (Chattogram-11), the prime minister said the government has set a target to create some 15 million jobs in the next five years.She said the present government has taken various measures to transform the young generation into human resources by creating jobs in the country in line with strategies and targets of the 7thfive-year plan (2016-20).

Ketterer et al. Nanoscale rotary apparatus formed from tight-fitting 3D DNA components, Science Advances (2016). DOI: 10.1126/sciadv.1501209AbstractWe report a nanoscale rotary mechanism that reproduces some of the dynamic properties of biological rotary motors in the absence of an energy source, such as random walks on a circle with dwells at docking sites. Our mechanism is built modularly from tight-fitting components that were self-assembled using multilayer DNA origami. The apparatus has greater structural complexity than previous mechanically interlocked objects and features a well-defined angular degree of freedom without restricting the range of rotation. We studied the dynamics of our mechanism using single-particle experiments analogous to those performed previously with actin-labeled adenosine triphosphate synthases. In our mechanism, rotor mobility, the number of docking sites, and the dwell times at these sites may be controlled through rational design. Our prototype thus realizes a working platform toward creating synthetic nanoscale rotary motors. Our methods will support creating other complex nanoscale mechanisms based on tightly fitting, sterically constrained, but mobile, DNA components. Play The assembly of the rotary apparatus. Credit: Philip Ketterer The tiny device built by the team represents the first example of a biologically inspired nanomachine capable of demonstrating dynamic motor-like behavior. It also represents a step forward in nanoarchitecture—the device was built molecule-by-molecule and perhaps is the first step towards the development of true nanorobots. They note also, that after watching their device in action, it is not difficult to envision such devices motoring around inside of people, in a way very similar to how bacteria get around.

In this new effort, the team in Germany has built a device based on synthetic DNA parts—it mimics, somewhat, the activities of flagella, the tiny arm-like appendages bacteria use as paddles to move around. It is only 40 nanometers tall but includes three main parts, a crank that spins, an axle bearing and a container to hold the other two parts together.It does not yet have a power source, thus it cannot be called a motorized device just yet, instead, it can move around due to thermal energy which creates colliding water molecules which in turn causes the crank to turn—the team cannot control the direction of the device yet either, but believe they may have a solution sometime in the near future. They plan to test ideas using laser heat, ion flow or even chemical reactions to cause the crank to turn, and hopefully allow for controlling direction. If they succeed such a tiny motorized device would be useful in more than just medical applications—it could also possibly be used to drive chemical syntheses or to pump molecules across barriers. (Phys.org)—A trio of researchers with Technische Universität München has built a nanoscale apparatus that could one day serve as the basis for an extremely tiny motorized device. In their paper published in the journal Science Advances, the team describes how they built their device, how it works, and where they plan to take the new technology.
