Most FRBs originate hundreds of millions of light-years away. This one came from inside the Milky Way.

Intel suffered a massive breach Thursday as 20 GB of internal documents were published online.

The confidential documents contain data on the internal designs of chipsets dating back to 2016.

The data were sent by an anonymous source to a Swiss software engineer, Till Kottmann, who specializes in uploading hacked documents. He does so, he has said, to encourage companies to exercise more caution concerning security and “to better find and assess potential issues.” But he admits he is also motivated to release unauthorized documents obtained from hackers “to free information” for all to see.

Electronic components that can process information with high levels of efficiency are crucial for the development of most contemporary devices and computational tools. Reconfigurable electronics, flexible systems that can change configurations to best utilize available hardware resources, are a possible solution for enhancing processing efficiency.

Researchers at Nanjing University and the National Institute for Materials Science in Japan have recently designed new reconfigurable circuits with advanced shape-morphing and information processing capabilities. These logic and neuromorphic circuits, presented in a paper published in Nature Electronics, were fabricated using 2-D tungsten diselenide, an inorganic compound commonly used in the development of electronics.

“Current mainstream reconfigurable circuits (such as the field programmable gate array, FPGA) are based on traditional silicon circuits, using P-type or N-type field effect transistors with ‘fixed’ electrical characteristics,” Feng Miao, the researcher who led the study, told TechXplore. “For example, PN junction is always reverse-biased, and varying the drain polarity does not add new switching functionalities. Thus, these reconfigurable circuits need to use a lot of transistor resources to build complex circuit structures and eventually realize reconfigurable computing capabilities at the circuit level.”

A security expert revealed this week that an exploit commonly used against Windows users who own Microsoft Office can sneak into MacOS systems as well.

A former NSA security specialist who addressed the Black Hat security conference this week summarized his research into the new use for a very old exploit.

Patrick Wardle explained that the exploit capitalizes on the use of macros in Microsoft Office. Hackers have long used the approach to trick users into granting permission to activate the macros, which in turn surreptitiously launch malicious code.

The life-givers of integrated circuits and quantum devices in silicon are small structures made from patches of foreign atoms called dopants. The dopant structures provide charge carriers that flow through the components of the circuit, giving the components their ability to function. These days the dopant structures are only a few atoms across and so need to be made in precise locations within a circuit and have very well-defined electrical properties. At present manufacturers find it hard to tell in a non-destructive way whether they have made their devices according to these strict requirements. A new imaging paradigm promises to change all that.

The imaging mode called broadband electric force microscopy, developed by Dr. Georg Gramse at Keysight technologies & JKU uses a very sharp probe that sends electromagnetic waves into a silicon chip, to image and localize dopant structures underneath the surface. Dr. Gramse says that because the microscope can use waves with many frequencies it can provide a wealth of previously inaccessible detail about the electrical environment around the dopant structures. The extra information is crucial to predicting how well the devices will ultimately perform.

The imaging approach was tested on two tiny dopant structures made with a templating process which is unique in achieving atomically sharp interfaces between differently doped regions. Dr. Tomas Skeren at IBM produced the world’s first electronic diode (a circuit component which passes current in only one direction) fabricated with this templating process, while Dr. Alex Kölker at UCL created a multilevel 3D device with atomic scale precision.

Artificial molecules could one day form the information unit of a new type of computer or be the basis for programmable substances. The information would be encoded in the spatial arrangement of the individual atoms—similar to how the sequence of base pairs determines the information content of DNA, or sequences of zeros and ones form the memory of computers.

Researchers at the University of California, Berkeley, and Ruhr-Universität Bochum (RUB) have taken a step towards this vision. They showed that atom probe tomography can be used to read a complex spatial arrangement of metal ions in multivariate metal-organic frameworks.

Metal-organic frameworks (MOFs) are crystalline porous networks of multi-metal nodes linked together by organic units to form a well-defined structure. To encode information using a sequence of metals, it is essential to be first able to read the metal arrangement. However, reading the arrangement was extremely challenging. Recently, the interest in characterizing metal sequences is growing because of the extensive information such multivariate structures would be able to offer.

Four Canadians battling incurable cancer have been approved by the Minister of Health, Patty Hajdu, to use psilocybin therapy in the treatment of their end-of-life distress. These 4 patients mark the first publicly-known individuals to receive a legal exemption from the Canadian Drugs and Substances Act to access psychedelic therapy, and the first known patients to legally use psilocybin since the compound became illegal in Canada in 1974. The decision comes after over 100 days of waiting for a response.

“ I would like to personally thank the Hon. Minister Hajdu and the team at the Office of Controlled Substances for the approval of my section 56 exemption. This is the positive result that is possible when good people show genuine compassion. I’m so grateful that I can move forward with the next step of healing” says Thomas Hartle, one the section 56 applicants battling cancer, from Saskatoon Saskatchewan.

Laurie Brooks, another applicant from British Columbia facing end-of-life distress states: “I want to thank the Health Minister and Health Canada for approving my request for psilocybin use. The acknowledgement of the pain and anxiety that I have been suffering with means a lot to me, and I am feeling quite emotional today as a result. I hope this is just the beginning and that soon all Canadians will be able to access psilocybin, for therapeutic use, to help with the pain they are experiencing, without having to petition the government for months to gain permission. Thanks also to TheraPsil for helping the four of us in this fight. To Thomas Hartel and the other two patients – I think of you often and wish you only good things, especially good health!”

Many organizations will likely look to technology as they face budget cuts and need to reduce staff. “I don’t see us going back to the staffing levels we were at prior to COVID,” says Brian Pokorny, the director of information technologies for Otsego County in New York State, who has cut 10% of his staff because of pandemic-related budget issues. “So we need to look at things like AI to streamline government services and make us more efficient.”

For 23 years, Larry Collins worked in a booth on the Carquinez Bridge in the San Francisco Bay Area, collecting tolls. The fare changed over time, from a few bucks to $6, but the basics of the job stayed the same: Collins would make change, answer questions, give directions and greet commuters. “Sometimes, you’re the first person that people see in the morning,” says Collins, “and that human interaction can spark a lot of conversation.”

But one day in mid-March, as confirmed cases of the coronavirus were skyrocketing, Collins’ supervisor called and told him not to come into work the next day. The tollbooths were closing to protect the health of drivers and of toll collectors. Going forward, drivers would pay bridge tolls automatically via FasTrak tags mounted on their windshields or would receive bills sent to the address linked to their license plate. Collins’ job was disappearing, as were the jobs of around 185 other toll collectors at bridges in Northern California, all to be replaced by technology.
