NEW DELHI: Among all the protests that have erupted across China following the strict quarantine measures enforced by the government for Covid-19, one form that has stood out is the display of a physics equation.

In images widely being circulated on social media, students of Beijing’s Tsinghua University can be seen holding sheets on which is written one of the Friedmann equations.

What these equations have to do with the subject of the protests is open to speculation. Many on social media have suggested that it is a play on the words “free man”. Another view is that it symbolises a free and “open” China, because the Friedmann equations describe an “open” (expanding) universe.

The Israeli government has teamed up with a defense contractor to invent a new material matrix that can hide soldiers from infrared sensors, making them more difficult to detect.

Polaris Defense’s Kit 300 system is a “thermal visual concealment” system that uses a combination of “metals, microfibres, and polymers” to mask a soldier’s thermal signature, according to Business Insider.

Thermal imaging technology creates a visual representation of an object via the invisible infrared (“heat radiation”) the object emits. If that object radiates heat, a thermal imager will show an image of it, with different colors representing relative levels of heat.

Elon Musk announced in a tweet today (Nov .25) that Twitter would launch its delayed color-coded “Verified” service on Friday next week.

The new service would feature a “gold check” for companies, a grey one for government accounts and the existing blue one for individuals, regardless of whether they are celebrities or not. See the tweet for yourself below:

The information security landscape is rapidly changing in response to quantum computing technology, which is capable of cracking modern encryption techniques in minutes, but a promising US government encryption algorithm for the post-quantum world was just cracked in less than an hour thanks to a decades-old math theorem.

In July 2022, the US National Institute of Standards and Technology (NIST) chose a set of encryption algorithms that it hoped would stand up to the encryption-cracking power of quantum computers and tasked researchers with probing them for vulnerabilities, offering a $50,000 prize for anyone who was able to break the encryption.

Neuralink’s invasive brain implant vs phantom neuro’s minimally invasive muscle implant. Deep dive on brain computer interfaces, Phantom Neuro, and the future of repairing missing functions.

Phantom is creating a human-machine interfacing system for lifelike control of technology. We are currently hiring skilled and forward-thinking electrical, mechanical, UI, AR/VR, and Ai/ML engineers. Looking to get in touch with us? Send us an email at [email protected].

Phantom Neuro.
Phantom is a neurotechnology company, spun out of the lab at The Johns Hopkins University School of Medicine, that is enabling lifelike control of robotic orthopedic technologies, such as prosthetic limbs and exoskeletons. Phantom’s solution, the Phantom X, consists of low-risk implantable sensors, AI, and enabling software. By providing superior control of robotic orthopedic mechanisms, the Phantom X will drastically improve the lives of individuals with limb difference who have yet to see a tangible improvement in quality of life despite significant advancements in the field of robotics.

Solar power could be gathered far away in space and transmitted wirelessly down to Earth to wherever it is needed. The European Space Agency (ESA) plans to investigate key technologies needed to make Space-Based Solar Power a working reality through its SOLARIS initiative. Recently in Germany, one of these technologies, wireless power transmission, was demonstrated to an audience of decision-makers from business and government.

The demonstration took place at Airbus’ X-Works Innovation Factory in Munich. Microwave beaming was used to transmit green energy between two points representing ‘Space’ and ‘Earth’ over a distance of 36 meters.

The received power was used to light up a model city and produce green hydrogen by splitting water. It even served to produce the world’s first wirelessly cooled 0% alcohol beer in a fridge before being served to the watching audience.

Guarding Against Future Global Biological Risks — Dr. Margaret “Peggy” Hamburg, MD — Chair Nuclear Threat Initiative, bio Advisory Group; Commissioner, Bipartisan Commission on Biodefense; former Commissioner, U.S. Food and Drug Administration (FDA)


Dr. Margaret “Peggy” Hamburg, MD is an internationally recognized leader in public health and medicine, who currently serves as chair of the Nuclear Threat Initiative’s (NTI) bio Advisory Group (https://www.nti.org/about/people/margaret-hamburg-md/), where she has also served as founding vice president and senior scientist. She also currently holds a role as Commissioner on the Bipartisan Commission on Biodefense (https://biodefensecommission.org/teams/margaret-a-hamburg/).

Dr. Hamburg previously served as foreign secretary of the National Academy of Medicine and is a former Commissioner of the U.S. Food and Drug Administration (FDA), having served for almost six years where she was well known for advancing regulatory science, modernizing regulatory pathways, and globalizing the agency. Previous government positions include Assistant Secretary for Planning and Evaluation, U.S. Department of Health and Human Services, Health Commissioner for New York City, and Assistant Director of the National Institute of Allergy and Infectious Diseases, National Institutes of Health.

As the US government begins to consider some of the legal implications for copyright in connection with the development and deployment of artificial intelligence, it is important to first step back to ensure that we are properly guided by context and a proper understanding of our goals — grounded in an informed grasp of the relationship of copyright to the development of AI, and a fair observation of the state of legal developments around the world. Far too many observers have oversimplified how various countries have addressed the relationship between copyright and AI. The reality is that all who have done so have rejected the notion that copyright is not implicated, and have developed legal norms which carefully limit the scope of any exceptions with an eye towards facilitating licensing, even when they seek to expand the development of AI as a national economic imperative.

I have written about the approach taken by the EU in the updated Copyright Directive, and note here that despite claims about Japan’s legislation, even their provisions — as manifested in the 2018 amendments, are designed to avoid conflict with the legitimate interests of copyright owners. While I don’t necessarily agree with Japan’s approach, it is important to highlight that even its exceptions, as I understand them: recognize that text and data mining/machine learning does in fact implicate copyright; apply only to materials that have been lawfully acquired; require that the use of each work is “minor” relative to the TDM effort; and provide that license terms must be honored. While it remains unclear to me that Japan’s goal of respecting copyright as required by international law has been achieved, it is important to understand that claims that Japan has removed copyright as an issue that must be addressed in the development of AI are inaccurate.
