Say goodbye to your camera bump: Miniaturized optics through new counterpart to lens

Posted by in categories: mobile phones, quantum physics, space

ANOTHER OPTICAL BREAKTHROUGH COMPLEMENTING METALENSES. In addition to the ongoing revolution in optical science brought about by flat metalenses and single-photon image sensors, there is another parallel and complementing new dimension now added to the mix, which, according to this article, will allow telescopes as thin as a piece of paper.


Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone?

In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives.

New connector for sustainable structures on Earth and in space

Posted by in categories: engineering, space, sustainability

As part of his Master’s degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures. His initial project has expanded into an online program for designing bamboo furniture that’s stylish, modular and customizable. And now his connector is being looked at for use by astronauts in outer space.

During his time at EPFL under the Erasmus program, Romain van Wassenhove came up with an idea for a connector that could be used to make modular structures out of sustainable rather than wood, plastic or metal. “I wanted to focus my Master’s on a topic that had meaning to me and that would lead to a concrete application,” he says. “Working with bamboo was something I already had in mind while I was studying in Brussels.” His connectors can be 3D-printed in biosourced plastic and are customizable to the type of material used for the structure.

Van Wassenhove got the idea for his connector during a class at EPFL on composite materials and developed the concept further through his Master’s project, co-directed at EPFL by Senior Scientist Anastasios Vassilopoulos and by associate professor Lars De Laet at Vrije Universiteit Brussel (VUB). In September 2020, soon after graduating, he obtained research funds—through an EPFL Ignition Grant—to enhance the design and operation of his connector and test it on an initial application involving bamboo structures. Today van Wassenhove’s invention is EU patent-protected, and his research has just been published in Composite Structures.

Across China, AI city brains are changing how the government runs

Posted by in categories: biotech/medical, government, robotics/AI, surveillance

It is called the “city brain”, an artificial intelligence system that is now being used across China – only megacities could afford them before – for everything from pandemic contact tracing to monitoring illegal public assemblies and river pollution.


Authorities at all levels are now using AI for everything from pandemic control to monitoring illegal public assemblies.

Emerging Ransomware Targets Dozens of Businesses Worldwide

Posted by in categories: business, cybercrime/malcode, energy, finance, food, government, law

An emerging ransomware strain in the threat landscape claims to have breached 30 organizations in just four months since it went operational, riding on the coattails of a notorious ransomware syndicate.

First observed in February 2021, “Prometheus” is an offshoot of another well-known ransomware variant called Thanos, which was previously deployed against state-run organizations in the Middle East and North Africa last year.

The affected entities are believed to be government, financial services, manufacturing, logistics, consulting, agriculture, healthcare services, insurance agencies, energy and law firms in the U.S., U.K., and a dozen more countries in Asia, Europe, the Middle East, and South America, according to new research published by Palo Alto Networks’ Unit 42 threat intelligence team.

Researchers create self-sustaining, intelligent, electronic microsystems from green material

Posted by in categories: bioengineering, biotech/medical, robotics/AI

A research team from the University of Massachusetts Amherst has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous living organism. The microsystem is constructed from a novel type of electronics that can process ultralow electronic signals and incorporates a device that can generate electricity “out of thin air” from the ambient environment.

The groundbreaking research was published June 7 in the journal Nature Communications.

Jun Yao, an assistant professor in the electrical and computer engineering (ECE) and an adjunct professor in biomedical engineering, led the research with his longtime collaborator, Derek R. Lovley, a Distinguished Professor in microbiology.

China set to launch first astronauts to space station with Shenzhou-12

Posted by in categories: engineering, satellites

HELSINKI — China rolled out a Long March 2F rocket Wednesday in preparation to send the Shenzhou-12 spacecraft and three astronauts to an orbiting space station module.

The Long March 2F rocket was vertically transferred to its pad at the Jiuquan Satellite Launch Center in the Gobi Desert, the China Manned Space Engineering Office (CMSEO) announced Wednesday.

The rocket will send Shenzhou-12 and three astronauts to the Tianhe core module for China’s space station which launched April 28 Eastern.

Nvidia acquires hi-def mapping startup DeepMap to bolster AV technology

Posted by in categories: mapping, robotics/AI, transportation

Chipmaker Nvidia is acquiring DeepMap, the high-definition mapping startup announced. The company said its mapping IP will help Nvidia’s autonomous vehicle technology sector, Nvidia Drive.

“The acquisition is an endorsement of DeepMap’s unique vision, technology and people,” said Ali Kani, vice president and general manager of Automotive at Nvidia, in a statement. “DeepMap is expected to extend our mapping products, help us scale worldwide map operations and expand our full self-driving expertise.”

One of the biggest challenges to achieving full autonomy in a passenger vehicle is achieving proper localization and updated mapping information that reflects current road conditions. By integrating DeepMap’s tech, Nvidia’s autonomous stack should have greater precision, giving the vehicle enhanced abilities to locate itself on the road.

Tesla is now looking to hire self-driving car test drivers around the world

Posted by in categories: education, robotics/AI, transportation

Do you want to work for Tesla remotely and test its latest Autopilot and Full Self-Driving features? You may be in luck as we learn that the automaker is now looking to hire self-driving car test drivers around the world.

You don’t even need a college education.

When it comes to Autopilot and Full Self-Driving package features, people often say that Tesla’s own paying customers are the testers and that’s mostly true, but the automaker also does plenty of internal testing.

Mass of Human Chromosomes Measured for the First Time – Mysteriously Heavier Than Expected

Posted by in category: biotech/medical

The mass of human chromosomes, which contain the instructions for life in nearly every cell of our bodies, has been measured with X-rays for the first time in a new study led by University College London (UCL) researchers.

For the study, published in Chromosome Research, researchers used a powerful X-ray beam at the UK’s national synchrotron facility, Diamond Light Source, to determine the number of electrons in a spread of 46 chromosomes which they used to calculate mass.

They found that the chromosomes were about 20 times heavier than the DNA they contained – a much larger mass than previously expected, suggesting there might be missing components yet to be discovered.
