Tags Share your voice Facebook has reportedly suspended three popular video pages designed to appeal to millennials after discovering the pages were backed by the Russian government. The pages, which Facebook suspended Friday, are run by Maffick Media, whose majority stakeholder is Ruptly, a subsidiary of Russia-backed RT, CNN reports. Facebook plans to contact the people running the pages and ask them to disclose their affiliations to get their pages back, CNN said. The move is unusual for Facebook, as it doesn’t require users to provide information about parent companies. But in an effort in increase transparency on the platform, Facebook has taken aggressive steps to identify covert government-supported information on its service. With more than 2 billion users worldwide, Facebook has been under pressure to reduce disinformation, hate speech and inauthentic behavior on the site. In 2017, the tech firm revealed it found evidence that Russians used the social network to meddle in the 2016 US presidential election and sow discord among Americans. Since then, Facebook has pulled down hundreds of accounts including some tied to influence campaigns by Iran. Facebook said that users shouldn’t be misled about who’s behind the pages they connect with. “Just as we’ve stepped up our enforcement of coordinated inauthentic behavior and financially motivated spam over the past year, we’ll continue improving so people can get more information about the Pages they follow,” a Facebook spokesman said in a statement. “For example, we’re now rolling out in phases an update to Pages with large audiences to include information about the primary countries they’re managed from. “Since this feature isn’t live yet for all, we’ll be reaching out to admins of these Pages to ask that they disclose this additional information and their affiliation with their parent company to get back on the platform,” Facebook said Maffick Media denied breaking Facebook’s rules. “We did not violate any of Facebook’s policies whatsoever. None of our content promotes disinformation or fake news,” the company said in a statement to its website Sunday. Disinformation has long been a part of Russia’s foreign policy strategy, and social media has allowed the trolling effort to expand on a viral scale. US intelligence agencies have warned Congress that these campaigns will continue in the future. The pages, which focused on current events, history and the environment, collected more than 30 million views since September, CNN reported.

Front Altair on fire.TwitterTwo oil tankers were attacked in the Gulf of Oman, according to a UK maritime security report. A similar incident in the region was reported last month when four oil tankers were attacked.The incident took place near the coast of the United Arab Emirates (UAE) near the strategic Strait of Hormuz.One of the two ships, the tanker ‘Front Altair’ managed by a Bermuda-owned shipping company Frontline, suffered a fire on Thursday morning while sailing through the southern end of the Strait of Hormuz. While the cause of the fire is yet to be ascertained, a spokesperson of the company told CNN that all the 23 crew members were evacuated and safe.The Iran state media, on the other hand, reported that the Front Altair had sunk, reported The Guardian.The vessel was identified as an oil tanker that was transporting Naptha (a type of crude oil) and was on its way to Taiwan. The other ship, Kokuka Courageous was reportedly attacked “thrice” with “some sort of shell” according to the spokesperson of the Japanese ship, reported CNN. All 21 crew members on board were evacuated in which one was reported to be injured. The ship was reportedly a goods carrier and was carrying methanol and was on route to Singapore, reported CNN. However, according to Japan’s Ministry of Economy, Trade and Industry, both tankers were carrying “Japan-related cargo.”Managed by the Singapore based company BSM, a company spokesperson said that the ship remains in the area and is not in danger of sinking.Michio Yuube, the co-manager of company Kokuka Sangyo said that the vessel was “first shot above sea level and then caught fire briefly before the blaze was extinguished”.Iran’s Foreign Minister Mohammad Javad Zarif Tweeted that “suspicious doesn’t begin to describe” the incident as it happened on the day Japan’s Prime Minister Shinzo Abe was on a state visit to Iran to meet Iran’s Supreme Leader Ayatollah Ali KhameneiReported attacks on Japan-related tankers occurred while PM @AbeShinzo was meeting with Ayatollah @khamenei_ir for extensive and friendly talks. Suspicious doesn’t begin to describe what likely transpired this morning. Iran’s proposed Regional Dialogue Forum is imperative.— Javad Zarif (@JZarif) June 13, 2019On June 6, according to the international investigation, the United Arab Emirates (UAE), Saudi Arabia and Norway told the United Nations Security Council in an informal meeting that there are “strong indications that the four attacks were part of a sophisticated and coordinated operation carried out with significant operational capacity.’Out of the four vessels attacked on May 12, two belonged to Saudi Arabia, while the remaining were owned by the UAE and Norway. The investigation did not mention the name of any country responsible behind the attack.

Over a span of two days D.C. police made arrests in a February shooting and a September stabbing that helped close two violent crime cases.On March 17, authorities said they arrested Delonte Mack, 29, Southwest, for suspected involvement in a Southwest shooting that happened on Feb. 25.Last month, a officer was patrolling in the Unit Block of N Street, SW when the officer heard the sound of gunshots nearby, police reported.Officials said the officer found a man lying out front of a restaurant on N Street, SW suffering from several gunshot injuries.The victim had been struck by gunfire in his buttocks, groin, foot and shoulder. The victim was taken to a local hospital and treated for his injuries.Mack was arrested and charged with assault with intent to kill while armed. Mack is scheduled to appear in court for a preliminary hearing on March 31, D.C. Courts said.On March 15, police made an arrest in a September stabbing that happened in the 5000 block of Bass Place, SE, police said.Authorities arrested Jeffrey Saunders, 31, and charged him with assault with intent to kill in the stabbing of a man on Sept. 27.Police said they found a man suffering from multiple stab wounds in the hallway of a Southeast apartment building around 2:55 a.m.A witness said he heard a woman screaming and came out into the hallway to see the victim on the floor face down bleeding from his injuries, police reported. The victim was taken to a local hospital and was treated for life threatening injuries.On Jan. 13, Chiquita Harris, 30, a resident of Southeast D.C., was arrested and charged with intent to kill in connection with the stabbing.A spokesperson for the department Alaina Gertz told the AFRO March 20 that the motives for both cases are unknown.

Credit: Mann and Garnett. ©2013 American Chemical Society Now, somewhat counterintuitively, scientists have theoretically found that thin semiconductor films wrapped around metal nanowires have substantially better light absorption properties than solid semiconducting nanowires, despite the fact that they use less semiconducting material. At the same time, the metal core acts as a contact to efficiently extract charge carriers. By confronting the semiconductor thickness trade-off and offering exceptional performance, the nanostructures might become ideal building blocks for inexpensive photovoltaic and solar fuel applications.A paper on the new devices by Sander A. Mann and Erik C. Garnett at the Center for Nanophotonics at FOM Institute AMOLF in Amsterdam, The Netherlands, will be published in a future issue of Nano Letters.”The greatest significance to our work is that we provide a design for nanowire building blocks that incorporates both excellent light trapping properties and a local metal electrode contact (for current extraction),” Garnett told Phys.org. “Silver nanowire networks have already been used as high performance transparent electrodes and we expect that by coating them with thin semiconducting shells we will be able to make high-efficiency solar cells using cheap materials. It has now been observed in a number of papers that nanostructuring a material can increase light absorption even while using less semiconductor material. However, this paper takes the next step and starts thinking about how to design such structures with integrated electrical contacts.” One of the biggest advantages of the design is that it uses very thin semiconducting films while at the same time providing very good light absorption. As mentioned, thick semiconductor layers are needed for good light absorption, but high-quality semiconductor is very costly. This new core-shell geometry opens up a pathway to using cheap, abundant, and environmentally friendly semiconductors that previously were of too low quality for good charge extraction.In semiconductor objects smaller than the wavelength of light, as is the case with most nanowires for photovoltaic purposes, the optical properties are determined primarily by resonances. These resonances enhance absorption the most when they are critically coupled: the loss rates due to absorption in the semiconductor and due to radiative leakage (light escaping the nanowire before being absorbed) are equal. This is often the case near the band gap of the material, where absorption is weak, which leads to the highly counterintuitive result that absorption in the nanowire actually increases when the absorption coefficient decreases.As the scientists explain, in the core-shell geometry, extreme light absorption arises from increasing the number and strength of these resonances. Whereas in horizontal nanowires resonances are always spectrally separated (at different wavelengths), in the core-shell geometry they can overlap. Furthermore, horizontal solid seminconductor nanowires are very polarization-sensitive, but this is undesirable as light from the sun is unpolarized. The core-shell geometry gets rid of this polarization dependence by aligning resonances in both polarizations simultaneously.Overall, by demonstrating that excellent light absorption can be achieved in very thin semiconductor layers, this hybrid nanostructure offers an exciting new path toward realizing inexpensive solar technologies based on abundant and environmentally friendly semiconductors. The researchers plan to fabricate prototypes of the devices soon.”Our immediate plans are to make both single-nanowire and array solar cells based on these core-shell building blocks to verify our calculations experimentally,” Garnett said. Explore further Nanowire solar cells raise efficiency limit (Phys.org) —In photovoltaics, there is generally a trade-off in terms of semiconductor thickness, with thicker semiconductors offering better photon absorption and thinner ones offering higher charge carrier extraction efficiency. In recent years, scientists have begun investigating semiconductor nanowire solar cells, which tackle this tradeoff through morphology-dependent resonances that significantly enhance the absorption compared to a planar film.
