Surgeries require a lot of planning, practice, and precision. Doctors cannot afford to get distracted or lose focus when operating on a person. The use of AI in surgery aims to support doctors and supply them with the necessary information and surgical tools without disturbing them at any point.

Mixed reality makes it possible to use technology to assist doctors during surgeries and minimize risks.

Paul Milgram and Fumio Kishino first introduced the term mixed reality in 1994 in their paper titled A Taxonomy of Mixed Reality Visual Displays. MR combines computer vision, cloud computing, graphical processing, etc., to blend the physical and virtual worlds. Many companies have been developing MR applications that can be used in various industries.

The innovative project Green H2-Hub Haren in the Emsland region in northern Germany uses H-Tec Systems electrolysers for sector integration.


The Green H2-Hub Haren project in Haren in Lower Saxony, northern Germany uses two electrolysers from H-Tec Systems. This was announced by project leader CEC Haren GmbH & Co. KG and electrolyser manufacturer H-Tec Systems. The order was placed with H-Tec Systems by the electricity and gas distribution network operator Westnetz. This research and development project is intended to enable the establishment of a decentralized hydrogen facility. At the site, green hydrogen will be produced from wind energy and stored in connection with specific regional applications, primarily for the mobility sector. The H2-Hub targets various hydrogen applications in rural areas – in particular in the field of agriculture – based on the production and use of sustainably generated hydrogen. In addition, the project is intended to significantly increase the city of Haren’s rate of self-sufficiently produced renewable energy. The goal is to implement a model that will also develop and prepare a comprehensive integration of other rural locations and regions in Lower Saxony into the H2 supply infrastructure.

The town of Haren aims to be completely self-sufficient with green energy. New storage systems as part of the H2 Hub enable a significant use of excess electricity from times of peak generation. The 16 wind turbines of the community wind farm Fehndorf-Lindloh are connected to a PEM electrolysis system, as well as an additional battery storage system in combination with a superordinate energy management system. In addition, a hydrogen filling station and a gas network feed-in point will be built. In this way, the project allows the transfer of surplus electricity to other sectors, such as heating or transport.

A key approach of sector integration in connection with renewable energies is to stabilize wind energy through PEM electrolysis with connected storage. The production of hydrogen will be realized with the help of two electrolysis systems from H-Tec Systems. This will enable new potential for the utilization of this energy in the form of power-to-gas or power-to-fuel.

Zone of Utopia + Mathieu Forest Architecte : The Xinxiang Cultural Tourism Center is the architectural icon of the new tourism district, which will be dedicated to winter sports, including the presence of the future indoor ski slope.

The entire district, with its exceptional facilities and shops, will attract many visitors from the city and the surrounding regions.

The ambition of the project is to create a strong urban indicator that unites the whole district. The project does not look like a classic building – it is not possible to figure out the number of floors. It is a sculpture out of scale, a pure and monumental volume.

Telecom provider AT&T this week said some local customers now have access to faster internet with the addition of 2 gigabit and 5 gigabit fiber internet to the community. Reno is one of more than 70 metro regions in the country to get the upgrade.

The top speeds for AT&T fiber internet had previously been 1 gig.

AT&T officials said the rollout of the improved fiber network for residential customers was in response to pandemic shifts in how people work, with many more people setting up home offices or making their homes a permanent workplace.

Scientists from the Kavli Institute for the Physics and Mathematics of the Universe and the University of Minnesota, Tomotake Matsumura and Shaul Hanany, and their collaborators have made a new type of optical element that will improve the performance of telescopes studying radiation from the Big Bang.

The (CMB) is a relic radiation remnant from the big bang. It reaches our telescopes after traveling 14 billion years since the birth of the Universe. Studying the properties of this radiation, scientists infer the physics of the , how clusters of galaxies form, and the matter and energy content in the Universe. Four Nobel prizes have been awarded for past studies of the CMB.

To study the CMB, telescopes must be tuned to wavelengths in which it is most intense, about 1–3 mm, and they must separate out shorter wavelength radiation that the atmosphere and Milky Way emit. Among the most effective optical elements that absorbs the short wavelength radiation but lets the CMB pass through is alumina, a material made of aluminum and oxygen and that is second in hardness only to diamond. One challenge with using alumina is that it also reflects almost 50% of the radiation impinging on it. Matsumura and Hanany have now come up with a new way to fabricate anti-reflective structures that reduce reflections fifty-fold.

Last fall, Texas Governor Greg Abbott gathered dozens of cryptocurrency deal makers in Austin where they discussed an idea that, on its face, seemed almost upside down: Electricity-hungry Bitcoin miners could shore up the state’s power grid, a top priority after a deep freeze last winter triggered blackouts that left hundreds dead.

The industry’s advocates have been making that pitch to the governor for years. The idea is that the miners’ computer arrays would demand so much electricity that someone would come along to build more power plants, something Texas badly needs. If the grid starts to go wobbly, as it did when winter storm Uri froze up power plants in February 2021, miners could quickly shut down to conserve energy for homes and businesses. At least two Bitcoin miners have already volunteered to do just that.

The Lifeboat Foundation is a nonprofit nongovernmental organization dedicated to encouraging scientific advancements while helping humanity survive existential risks and possible misuse of increasingly powerful technologies, including genetic engineering, nanotechnology, and robotics/AI, as we move towards the Singularity.

Lifeboat Foundation is pursuing a variety of options, including helping to accelerate the development of technologies to defend humanity, such as new methods to combat viruses, effective nanotechnological defensive strategies, and even self-sustaining space colonies in case the other defensive strategies fail.

We believe that, in some situations, it might be feasible to relinquish technological capacity in the public interest (for example, we are against the U.S. government posting the recipe for the 1918 flu virus on the internet). We have some of the best minds on the planet working on programs to enable our survival. We invite you to join our cause!

A platform for single-molecule measurement of binding kinetics & enzyme activity.

The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore’s Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with real-time, single-molecule sensitivity and unlimited scalability in sensor pixel density. This innovation, appearing this week in a peer-reviewed article in the Proceedings of the National Academy of Sciences (PNAS), will power advances in diverse fields that are fundamentally based on observing molecular interactions, including drug discovery, diagnostics, DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

China successfully launched the Gongjian Ludi Tance-1 01A (L-SAR 01A) satellite into a quasi sun-synchronous orbit of 607 kilometers. The 3.2 metric ton satellite was launched at 23:44 UTC on Tuesday, January 25 on a Chang Zheng 4C from the Jiuquan Satellite Launch Center.

The satellite is equipped with an L-band and multi-channel synthetic aperture radar (SAR) payload. It is a civilian satellite that will use a 33 square meter array to survey the Earth after major events such as earthquakes and landslides.

This is comparable to the Argentinian SAOCOM satellites which are also equipped with L-band and a SAR to monitor environmental disasters. L-band brings the advantage of being able to penetrate clouds, rain, and vegetation which makes it easier to monitor the ground. It operates in a frequency range of 1–2 GHz.
