The Chinese private spaceflight company Galactic Energy has made the second flight of its Ceres-1 rocket, carrying five satellites into orbit, including a satellite known as Golden Bauhinia-1–03. The launch took place at 04:12 UTC on Tuesday, December 7th (12:12 Beijing time) from the Jiuquan Satellite Launch Center.

The Ceres-1 is a four-stage rocket, using three solid-fueled stages with a hydrazine-fueled fourth stage to complete orbital insertion and refinement. Ceres-1 is capable of launching a payload of up 400 kilograms to low Earth orbit, or up to 230 kilograms into a sun-synchronous orbit at an altitude of 700 kilometers.

Also known as Gushenxing-1, Ceres-1 was developed by Galactic Energy, one of several Chinese companies currently fielding or testing small solid-fueled satellite launchers. The first Ceres-1 launch was conducted successfully on November 7, 2020, making Galactic Energy the second private Chinese company to launch a satellite into low Earth orbit.

Have your oranges gone bad? No need to throw them in the bin because University of Sydney PhD student Pooria Lesani has developed a cancer detection technique made from the juice of rancid oranges.

In a study, published in Chemical Engineering Journal, Lesani described the orange-based, low-cost probe, which proved to be a useful nanobiosensor for screening cells that may be at risk of cancer.

The nanobiosenser is a tiny probe that “glows” fluorescently in human cells, and signals if those cells become acidic, indicating that cancer is not far off. This shows which cells are at greatest risk of cancer, so preventative measures can be taken.

Nearly 1 in 5 people with hypertension may be unintentionally taking a drug for another condition that causes their blood pressure to climb even higher, a new study suggests.

Left untreated or undertreated, high blood pressure will increase your risk for heart attack, stroke, kidney disease and vision problems by damaging blood vessels. Lifestyle changes such as weight loss, restricting salt intake, and/or medication can help move your blood pressure numbers back into the normal range. But asking your doctor whether any drugs you are taking for other conditions might be pushing those numbers up is worth the effort, the researchers said.

“The risk of [drugs] raising blood pressure may be simply overlooked, particularly for patients using these additional medications for many years,” said study author Dr. Timothy Anderson. He is a clinician investigator and an assistant professor of medicine at Harvard Medical School in Boston.

One of the world’s largest battery-based energy storage systems, powered by Tesla’s utility-scale Megapack batteries, began operating in the Australian state of Victoria on Wednesday.

Large energy storage systems based on lithium-ion batteries have the potential to prevent blackouts and let utilities store and use more energy generated from renewable but intermittent sources, like solar or wind.

Paris-based renewable energy giant Neoen developed the facility with partners Tesla Energy and AusNet, with some construction by Cimic Group’s UGL. It has enough capacity to power one million homes for half an hour, according to the web site for the project.

Bigger isn’t always better. DeepMind’s Gopher system uses smarter algorithms to make better choices. And it blows GPT-3 away.

The future of computing may be analog.

The digital design of our everyday computers is good for reading email and gaming, but today’s problem-solving computers are working with vast amounts of data. The ability to both store and process this information can lead to performance bottlenecks due to the way computers are built.

The next computer revolution might be a new kind of hardware, called processing-in-memory (PIM), an emerging computing paradigm that merges the memory and processing unit and does its computations using the physical properties of the machine—no 1s or 0s needed to do the processing digitally.

A team at Swiss-Mile, a spinoff of ETH Zurich has improved upon its ANYmal robot by giving it wheels—the result is known as the Swiss-Mile Robot. And by giving it wheels, the robot is now classified as a car, a quadruped and a humanoid robot, depending on its activity at any given time. Like the original ANYmal, the Swiss-Mile has a cartoonish look about it, as if it rolled out of one of the Pixar “Cars” movies.

It is also deceptively agile. In car mode, it rolls on the ground like a remote-controlled toy car but with much better abilities. It can roll up and down stairs and over objects it has never encountered without hesitation. It keeps on rolling with gusto, moving over any obstacle in its path, lifting up whatever wheels may need lifting, making it a rolling, stepping quadruped. But then it lifts its front end off the ground and rolls or walks on its two rear wheels, like a human on roller skates. Adding wheel lock has really given the robot a lot of options, allowing it to stop rolling, if need be, and to walk on two or four feet.

Georgia Tech Research Institute (GTRI) scientists announced they’ve made significant advances toward creating a chip that can grow DNA strands in a tightly packed, ultra-dense format for large storage capacity at very low cost.

Police departments all over the world are warming up to electric vehicles and their findings after using EVs on a daily basis are encouraging.

Earlier this year, the Westport Police Department in Connecticut shared some interesting conclusions after buying a Tesla Model 3 in December 2019. They found the EV to be not only cheaper to buy than the Ford Explorer SUV they typically use but also more affordable to modify, maintain, and run, leading to savings of about $6,000 a year.
