Over the past few years, scientists have been trying to understand how listening to music affects your brain. One of the features of music that seems to be important is whether you have an emotional connection to it. In other words, listening to a favorite tune will have a different effect on your brain than an unknown or disliked piece of music.

Now, a new study has shown that people with Alzheimer’s Disease can improve their cognition by listening to music that has personal meaning to them, such as songs they’ve been listening to for years.

Researchers Corinne Fischer, Nathan Churchill and colleagues from the University of Toronto ran a small study to find out what exactly happens when people with Alzheimer’s listened to their favorite songs. They asked fourteen people with early stage Alzheimer’s Disease to spend one hour per day listening to music they enjoyed and were very familiar with. Before and after the test period all participants also took a cognitive test, and had their brain activity measured by functional MRI (fMRI).

Welcome to a world with electric skies.

Rolls-Royce claims that its all-electric aircraft, called “Spirit of Innovation”, reached a top speed of 387.4 mph (623km/h), making it the fastest electric vehicle in the world, a press statement reveals.

Rolls-Royce believes it has set three new world records, with the top speed for an electric aircraft, the fastest time to climb to 3,000 meters with a time of 202 seconds, and the fastest speed over 9.3 miles (15 kilometers) at 182 m… See more.

Get ready for the ‘White Bat’.

What’s the best way to counter gossip? Coming out with the truth. That seems to be the idea behind a new video released by the U.S. Air Force’s Profession of Arms Center of Excellence (PACE).

The video that was released earlier this month recounts the ways intelligence gathering, surveillance, and reconnaissance (ISR) have improved over the decades. The U.S. has moved far ahead from the days when balloons were sent up in the air to understand what was happening behind enemy lines. Adversaries of the U.S. are now a world away and the military still has the ability to “find the unfindable.”

But it might not be a success, warns Elon Musk.

SpaceX’s launch vehicle scheduled to take humans back to the Moon is expected to make its first orbital flight as early as January 2022.

Speaking in a video call at the fall meeting of the National Academies of Sciences, Engineering, and Medicine, CEO Elon Musk said that SpaceX is scheduled to carry out some tests in December, ahead of Starship’s first orbital flight in January, Business Insider reported.

The biggest launch vehicle built to date, SpaceX’s Starship consists of two parts, a first stage booster called Super Heavy and the actual spacecraft that gives it the name, Starship. Both these components are powered by SpaceX’s Raptor engines but differ in capacities. When finally ready, the Super Heavy is expected to have 33 Raptor engines while the spacecraft will have just six. Both components are designed to be reusable and are expected to play an important role in taking humankind to Moon, Mars, and even beyond, Space reported.

The team has set an internal deadline of 2025.

In a move that could peg it against electric vehicle market leader, Tesla, Apple has begun working aggressively on its fully autonomous electric car, Bloomberg reported. Developing a car has been on Apple’s agenda since 2014 but recent moves within the company signal a push towards making an Apple car a reality.

Given Apple’s history of taking regularly used products and transforming them into their must-have versions using excellent design, it is hardly a surprise. With Steve Jobs at the helm of affairs, Apple made the iPod even when music players were ubiquitous. Then the company revealed the iPhone when Nokia was still selling resistive touch screens as its premium product. And recently, the Apple Watch has become the “it” wearable even though there are other smartwatch options in the market. During a time where electric vehicles are in a surge, it only seems natural that the electric car is Apple’s next target.

By using ‘the holy grail of low drag.’

Business travel is going egg-shaped. Otto Aviation’s Celera 500L was just put through its paces with its first flight tests, a press statement reveals. The aircraft was designed as a business aircraft that is much cheaper to run than today’s options.

To achieve this ambitious goal, the Celera employs an egg-like design that achieves laminar flow — the uninterrupted flow of air — when in flight, vastly reducing drag by allowing air to flow smoothly over the aircraft’s surface.

Glaucoma is a surprisingly common condition that can have serious consequences if it goes untreated. Understanding the importance of early detection, a team of engineers and ophthalmologists in Australia has developed a novel approach using AI to diagnose glaucoma that can yield results in just 10 s.


Have you ever experimented with food dye? It can make cooking a lot more fun, and provides a great example of how two fluids can mix together well—or not much at all.

Add a small droplet in water and you might see it slowly dissolve in the larger liquid. Add a few more drops and perhaps you’ll see a wave of color spread, the colored droplets spreading and breaking apart to diffuse more thoroughly. Add a spoon and begin stirring quickly, and you’ll probably find that the water fully changes color, as desired.

Researchers at the USC Viterbi School of Engineering, led by Ivan Bermejo-Moreno, assistant professor of aerospace and mechanical engineering, studied a similar phenomenon with gases at high speeds, with an eye toward more efficient mixing to support supersonic scramjet engines. In the study, published in Physics of Fluids, USC Viterbi Ph.D. Jonas Buchmeier, along with Xiangyu Gao (USC Viterbi Ph.D. ‘20) and former visiting M.Sc. student Alexander Bußmann (Technical University Munich), developed a novel tracking method that zoomed in on the fundamentals of how mixing happens. The study helps understand, for example, how injected fuel interacts with the surrounding oxidizers (air) in the engine to make it operate optimally, or how interstellar gases mix after a supernova explosion to form new stars. The method focuses on the geometric and physical properties of the turbulent swirling motions of gases and how they change shape over time as they mix.

Sources “familiar with the matter” told Bloomberg that the team in charge of developing the Apple Car was previously stuck choosing between two different developments paths: a more traditional EV with some enhanced driver-assist features similar to what you get from a number of existing vehicles, or a more sophisticated EV capable of a true autonomous driving with no input from its passengers.

Now, based on Bloomberg’s report, it seems Project Titan (Apple’s codename for the Apple Car) and new project leader Kevin Lynch have decided to go the latter route, with Apple looking to create a fully autonomous vehicle with no pedals or steering.

Of course, deciding to make a true self-driving car is easier said than done, as no automaker has yet to release a proper Level 5 autonomous vehicle, defined as a car that can pilot itself without any human intervention under any conditions or driving situations.
