Harness launches Gitness, an open-source GitHub competitor

Posted by in categories: engineering, security

Since its launch in 2017, Harness, the software delivery platform founded by AppDynamics founder and CEO Jyoti Bansal, expanded from being continuous code deployment to covering continuous integration, feature flags, cloud cost management, security testing orchestration, chaos engineering and more. But even though it focused heavily on GitOps, it never offered its own Git repositories. That’s changing today with the launch of the Gitness open-source Git repository and the Harness Code Repository, the hosted and managed version of Gitness.

“There hasn’t been a new Git repo launch in almost a decade,” Bansal told me. “Now you have GitHub, GitLab, Bitbucket from Atlassian, but that’s really it. […] If you look at any of the git repos, whether it’s GitLab or GitHub or Bitbucket, they don’t have the true one source ethos around them anymore. We strongly believe that Git started as open source, so let’s bring the true open-source ethos back to Git repos.”

Seattle startup performs ‘100% reusable’ spacecraft test hop

Posted by in categories: Elon Musk, engineering, space travel

The Seattle-based company aims to build a “100% reusable” spacecraft capable of an ambitious 24-hour mission turnaround time.

Seattle-based startup Stoke Space successfully landed its reusable second-stage rocket this week following a brief hop test reminiscent of SpaceX’s early Starship tests.

The recent test, called Hopper 2, allowed Stoke Space to successfully test several novel engineering concepts, some of which were considered by Elon Musk’s SpaceX but ultimately discarded.

Copper-infused nanocrystals boost infrared light conversion

Posted by in categories: energy, engineering, nanotechnology, sustainability

Sunlight is an inexhaustible source of energy, and utilizing sunlight to generate electricity is one of the cornerstones of renewable energy. More than 40% of the sunlight that falls on Earth is in the infrared, visible and ultraviolet spectra; however, current solar technology utilizes primarily visible and ultraviolet rays. Technology to utilize the full spectrum of solar radiation—called all-solar utilization—is still in its infancy.

A team of researchers from Hokkaido University, led by Assistant Professor Melbert Jeem and Professor Seiichi Watanabe at the Faculty of Engineering, have synthesized tungstic acid–based materials doped with copper that exhibited all-solar utilization. Their findings are published in the journal Advanced Materials.

“Currently, the near-and mid-infrared spectra of solar radiation, ranging from 800 nm to 2,500 nm, is not utilized for energy generation,” explains Jeem. “Tungstic acid is a candidate for developing nanomaterials that can potentially utilize this spectrum, as it possesses a crystal structure with defects that absorb these wavelengths.”

New nanotech weapon takes aim at hard-to-treat breast cancer

Posted by in categories: biotech/medical, chemistry, engineering, nanotechnology

Breast cancer in its various forms affects more than 250,000 Americans a year. One particularly aggressive and hard-to-treat type is triple-negative breast cancer (TNBC), which lacks specific receptors targeted by existing treatments. The rapid growth and metastasis of this cancer also make it challenging to manage, leading to limited therapy options and an often poor prognosis for patients.

A promising new approach that uses minuscule tubes to deliver cancer-fighting drugs directly to the tumor site while preserving has been developed by Johns Hopkins engineers. The team’s research appeared in Nanoscale.

“In this paper, we showed that we can use to specifically target both proliferating and senescent TNBC cells with chemotherapeutics and senolytics, killing them without targeting healthy breast cells,” said Efie Kokkoli, professor of chemical and biomolecular engineering, a core researcher at the Johns Hopkins Institute for NanoBioTechnology, and a specialist in engineering targeted nanoparticles for the delivery of cancer therapeutics.

A zero-carbon transport sector needs smart EV charging

Posted by in categories: engineering, government, sustainability, transportation

Decarbonising Australia’s transport systems will take more than a transition to electric vehicles. Understanding how and when owners like to charge their cars is important. Our researchers are examining how we might persuade the increasing electricity demand to meet the time-dependent renewable energy supply.

How many people do you know who own an electric vehicle? Most Australians still drive petrol-fuelled cars. But the proportion of electric vehicles (EVs) on our roads is set to boom in coming years, particularly if the government’s plans to introduce a fuel efficiency standard prove successful.

Transport researchers at the University of Melbourne Faculty of Engineering and Information Technology have studied the expectations EV owners have for charging – and what they think of policies and technologies that aim to shape EV charging behaviours.

A linear path to efficient quantum technologies

Posted by in categories: computing, engineering, quantum physics

Researchers at the University of Stuttgart have demonstrated that a key ingredient for many quantum computation and communication schemes can be performed with an efficiency that exceeds the commonly assumed upper theoretical limit—thereby opening up new perspectives for a wide range of photonic quantum technologies.

Quantum science has not only revolutionized our understanding of nature—it is also inspiring groundbreaking new computing, communication and sensor devices. Exploiting in such “quantum technologies” typically requires a combination of deep insight into the underlying quantum-physical principles, systematic methodological advances, and clever engineering.

And it is precisely this combination that researches in the group of Prof. Stefanie Barz at the University of Stuttgart and the Center for Integrated Quantum Science and Technology (IQST) have delivered in a recent study, in which they have improved the efficiency of an essential building block of many quantum devices beyond a seemingly inherent limit. The work is published in the journal Science Advances.

Experimental quantum imaging distillation with undetected light

Posted by in categories: engineering, quantum physics

It is possible to image an object with an induced coherence effect by making use of photon pairs to gain information on the item of interest—without detecting the light probing it. While one photon illuminates the object, its partner alone is detected, thereby preventing the measurements of coincidence events to reveal information of the sought after object. This method can be made resilient to noise, as well.

In a new report published in Science Advances, Jorge Fuenzalida and a team in applied optics, precision engineering and theory communications in Germany experimentally showed how the method can be made resilient to noise. They introduced an imaging-distilled approach based on the interferometric modulation of the signal of interest to generate a high-quality image of an object regardless of the extreme noise levels surpassing the actual signal of interest.

Quantum imaging is a promising field that is emerging with valid advantages when compared to classical protocols. Researchers have demonstrated this method across different scenarios to work in the low-photon flux regime by making use of undetected probing photons for super-resolution imaging.
