Thermoelectric paint enables walls to convert heat into electricity

Already researchers have developed photovoltaic paint, which can be used to make “paint-on solar cells” that capture the sun’s energy and turn it into electricity. Now in a new study, researchers have created thermoelectric paint, which captures the waste heat from hot painted surfaces and converts it into electrical energy.

“I expect that the thermoelectric painting technique can be applied to waste heat recovery from large-scale heat source surfaces, such as buildings, cars, and ship vessels,” Jae Sung Son, a coauthor of the study and researcher at the Ulsan National Institute of Science and Technology (UNIST)

Surveillance camera compromised in 98 seconds

Robert Graham, CEO of Errata Security, on Friday documented his experience setting up a $55 JideTech security camera behind a Raspberry Pi router configured to isolate the camera from his home network.

According to Graham’s series of Twitter posts, his camera was taken over by the Mirai botnet in just 98 seconds. Note: it was infected by another botnet first and then after 98 seconds by Mirai

Mirai conducts a brute force password attack via telnet using 61 default credentials to gain access to the DVR software in video cameras and to other devices such as routers and CCTV cameras.

After the first stage of Mirai loads, “it then connects out to download the full virus,” Graham said in a Twitter post. “Once it downloads that, it runs it and starts spewing out SYN packets at a high rate of speed, looking for new victims.”

Graham said the defense recommended by the Christian Science Monitor – changing the default password of devices before connecting them to the Internet – doesn’t help because his Mirai-infected camera has a telnet password that cannot be changed.

“The correct mitigation is ‘put these devices behind your firewall’,” Graham said.

Royal Navy to lose missiles and be left only with guns

Royal Navy warships will be left without anti-ship missiles and be forced to rely on naval guns because of cost-cutting, the Ministry of Defence has admitted.

The Navy’s Harpoon missiles will retire from the fleet’s frigates and destroyers in 2018 without a replacement, while there will also be a two year gap without helicopter-launched anti-shipping missiles.

Naval sources said the decision was “like Nelson deciding to get rid of his cannons and go back to muskets” and one senior former officer said warships would “no longer be able to go toe-to-toe with the Chinese or Russians”.

Britain has passed the ‘most extreme surveillance law ever passed in a democracy’

The UK has just passed a massive expansion in surveillance powers, which critics have called “terrifying” and “dangerous”.

The new law, dubbed the “snoopers’ charter”, was introduced by then-home secretary Theresa May in 2012, and took two attempts to get passed into law following breakdowns in the previous coalition government.

Four years and a general election later — May is now prime minister — the bill was finalized and passed on Wednesday by both parliamentary houses.

But civil liberties groups have long criticized the bill, with some arguing that the law will let the UK government “document everything we do online”.

It’s no wonder, because it basically does.

The law will force internet providers to record every internet customer’s top-level web history in real-time for up to a year, which can be accessed by numerous government departments; force companies to decrypt data on demand — though the government has never been that clear on exactly how it forces foreign firms to do that that; and even disclose any new security features in products before they launch.

Not only that, the law also gives the intelligence agencies the power to hack into computers and devices of citizens (known as equipment interference), although some protected professions — such as journalists and medical staff — are layered with marginally better protections.

In other words, it’s the “most extreme surveillance law ever passed in a democracy,” according to Jim Killock, director of the Open Rights Group.

NIH Scientists Identify Potent Antibody that Neutralizes Nearly All HIV Strains

Scientists from the National Institutes of Health have identified an antibody from an HIV-infected person that potently neutralized 98 percent of HIV isolates tested, including 16 of 20 strains resistant to other antibodies of the same class. The remarkable breadth and potency of this antibody, named N6, make it an attractive candidate for further development to potentially treat or prevent HIV infection, say the researchers.
