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.
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.
Watching the Swiss-Mile in action, such as in this YouTube video or this one, one thing is very clear: Wheels are much more efficient in many instances than feet. The robot looks eager to go as it rolls around engaging in acts of nimble agility. Also, unlike Big Dog or its cousins, Swiss-Mile never seems to lose its cool or to hesitate. It never looks afraid to plow forward, like a puppy who has not yet learned that sometimes doing stuff can hurt or result in damage.
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.
Now, new data is coming in from the UK, where several Tesla Model 3s custom built by Tesla UK as patrol cars have completed nine months of initial trials with the police. Max Toozs-Hobson, account manager and emergency services lead at Tesla, shared the findings on LinkedIn and said the Model 3 police cars have been “getting some great results.”

Israeli drone manufacturer Airobotics has collaborated with Israeli solar farm services company Solar Drone to develop and supply to Solar Drone a unique solar panel cleaning drone system. The fully automated system will include a drone docking station for automatic battery replacement and cleaning fluid replenishment, enabling the system to operate continuously.
While solar power and solar panels are essentially maintenance-free systems, but solar panels do require cleaning from time to time to enable proper function. Dirt, dust, mud, and bird dropping greatly reduce solar panel efficiency, impacting power output. Frequent cleaning is expensive and time-consuming, especially when panels are remote, difficult to access, or difficult to clean.
A new “drone-in-a-box”-type system is now being developed to do this job. A quadrocopter is housed inside a weatherproof dock located near the solar panels. At regular intervals, the station doors on top will open, releasing the drone. The drone will then take off and fly up to the panels, using LiDAR sensors and mapping cameras for more accurate positioning. Each panel will be sprayed with a cleaning fluid, and after completing the task, the drone will return to the docking station. If necessary, the robotic system will replace the discharged battery with the charged one and replace its cleaning fluid container with a full one.
