BBC to Launch Five New HD Channels
 Posted: 20 Jul 2013 05:00 AM PDT NASA has announced that it has successfully tested a 3D printed part for a rocket engine. The technique called selective laser melting (SLM) was used and resulted in the part being produced quicker and cheaper. The California based Aerojet Rocketdyne were able to make an injector component, a part that is used to deliver liquid oxygen and hydrogen gas to an engine’s combustion chamber.  Using the SLM method, a computer-designed object is turned into a real part by using high-powered laser beams that melt and fuse thin layers of metallic powders into the designed shape. According to NASA an injector component would normally take a year to make but by using this technique, they have been able to cut production time to less than four months and reduce the cost by more than 70 per cent. The test part is not full scale, it is smaller than what would normally be used in a full-size rocket but it is still big enough to give proof that the part is able to withstand the pressure and heat it would be exposed to. “Nasa recognises that on Earth and potentially in space, additive manufacturing can be game-changing for new mission opportunities, significantly reducing production time and cost by ‘printing’ tools, engine parts or even entire spacecraft,” said Michael Gazarik, Nasa’s associate administrator for space technology. The space agency are also exploring other techniques. It has asked researches at Washington University to explore the possibilites of producing 3D printed objects from lunar rocks. It is also testing a process called electron beam freeform fabrication (EBF3), which uses a computer controlled electron beam gun in a vacuum that then welds metal wires into complex shapes and patterns. All these techniques are making steps towards NASA’s astronauts being able to produce spare parts in space, thus saving more time and money during space exploration. |
BBC to Launch Five New HD Channels Posted: 20 Jul 2013 03:00 AM PDT The BBC has announced it plans to launch five new high definition channels by early next year. There will be High Definition versions of BBC News, CBBC, CBeebies, BBC Three and BBC Four. These channels will be available over rooftop aerials via Freeview receivers as well as cable and satellite services. This news coincides with the regulator Ofcom‘s announcement that is making it possible to launch a total of 10 new HD channels using airwaves freed up by the switch off of the old analogue TV signals. ITV, Channel 4 and Channel 5 had no statement at this time as to whether they intended to take advantage of Ofcom’s move. Surprisingly BSkyB said it had no plans to launch an HD service on Freeview. BBC’s director general Tony Hall said “BBC One HD and BBC Two HD have already proved to be highly valued by our audiences and I’m delighted that we’re able to follow this with the launch of five new subscription-free BBC HD channels by early 2014…These new channels will allow us to showcase more of our programming at its very best.” Currently there are four HD channels offered over Freeview, which launched its High Definition service in 2010. They are BBC One HD, BBC Two HD, ITV HD and Channel 4 HD. These include variants of the BBC One HD service for Scotland, Wales and Northern Ireland.  Two of the BBC’s new channels, BBC Three HD and CBBC HD, will utilise existing unused capacity, and CBeebies HD and BBC Four HD will share a channel since they will not be broadcast at the same time. As a result there is still the potential for up to a further eight new HD channels to be offered over Freeview as a result of Ofcom’s move. Transmission company Arqiva will provide the infrastructure behind the new Freeview services, having being awarded a licence to do so by the regulator. It will handle other applications for the added capacity. The company has indicated that up to 70% of the UK population should be able to receive the new channels over their aerials. The 550-606MHz spectrum band being used was freed up as a result of the UK’s digital TV switchover, which was completed last year. Ofcom has said it reserves the right to take back the bandwidth from December 2018 if it needs to prevent a “capacity crunch” caused by the roll-out of future mobile broadband services. The BBC has indicated it also wants to launch English regional variants of its existing BBC One HD service as well as Wales, Scotland and Northern Ireland editions of BBC Two HD. This would not need any of the new capacity, it would, however, need to be approved by the BBC Trust. Currently more than 50% of homes in the United Kingdom are already HD-enabled. The BBC said it expected that figure to grow a further 40% to around 90% by 2019. |
UN Warns on Mobile Cybersecurity Bugs to Prevent Attacks
BOSTON — A United Nations group that advises nations on cybersecurity plans to send out an alert about significant vulnerabilities in mobile phone technology that could potentially enable hackers to remotely attack at least half a billion phones.
The bug, discovered by German firm, allows hackers to remotely gain control of and also clone certain mobile SIM cards.
The bug, discovered by German firm, allows hackers to remotely gain control of and also clone certain mobile SIM cards.
Hackers could use compromised SIMs to commit financial crimes or engage in electronic espionage, according to Berlin's Security Research Labs, which will describe the vulnerabilities at the Black Hat hacking conference that opens in Las Vegas on July 31.
The U.N.'s Geneva-based International Telecommunications Union, which has reviewed the research, described it as "hugely significant."
"These findings show us where we could be heading in terms of cybersecurity risks," ITU Secretary General Hamadoun Touré told Reuters.
He said the agency would notify telecommunications regulators and other government agencies in nearly 200 countries about the potential threat and also reach out to hundreds of mobile companies, academics and other industry experts.
A spokeswoman for the GSMA, which represents nearly 800 mobile operators worldwide, said it also reviewed the research.
"We have been able to consider the implications and provide guidance to those network operators and SIM vendors that may be impacted," said GSMA spokeswoman Claire Cranton.
Nicole Smith, a spokeswoman for Gemalto NV, the world's biggest maker of SIM cards, said her company supported GSMA's response.
"Our policy is to refrain from commenting on details relating to our customers' operations," she said.
Becoming the SIM
Cracking SIM cards has long been the Holy Grail of hackers because the tiny devices are located in phones and allow operators to identify and authenticate subscribers as they use networks.
Karsten Nohl, the chief scientist who led the research team and will reveal the details at Black Hat, said the hacking only works on SIMs that use an old encryption technology known as DES. The technology is still used on at least one out of eight SIMs, or a minimum of 500 million phones, according to Nohl.
The ITU estimates some 6 billion mobile phones are in use worldwide. It plans to work with the industry to identify how to protect vulnerable devices from attack, Touré said.
Once a hacker copies a SIM, it can be used to make calls and send text messages impersonating the owner of the phone, said Nohl, who has a doctorate in computer engineering from the University of Virginia.
"We become the SIM card. We can do anything the normal phone users can do," Nohl said in a phone interview. "If you have a MasterCard number or PayPal data on the phone, we get that too."
IPhone, Android, BlackBerry
The mobile industry has spent several decades defining common identification and security standards for SIMs to protect data for mobile payment systems and credit card numbers. SIMs are also capable of running apps.
Nohl said Security Research Labs found mobile operators in many countries whose phones were vulnerable, but declined to identify them. He said mobile phone users in Africa could be among the most vulnerable because banking is widely done via mobile payment systems with credentials stored on SIMs.
All types of phones are vulnerable, including iPhones from Apple Inc, phones that run Google Inc's Android software and BlackBerry Ltd smartphones, he said.
BlackBerry's director of security response and threat analysis, Adrian Stone, said in a statement that his company proposed new SIM card standards last year to protect against the types of attacks described by Nohl, which the GSMA has adopted and advised members to implement.
Apple and Google declined comment.
CTIA, a U.S. mobile industry trade group based in Washington, D.C., said the new research likely posed no immediate threat.
"We understand the vulnerability and are working on it," said CTIA Vice President John Marinho. "This is not what hackers are focused on. This does not seem to be something they are exploiting."
