Tesla vehicles are equipped with extrernal speakers.
The main function is to output a pedestrian warning sound, which has become required for electric vehicles in many markets due to the fact that they are quiet at low speeds.
Tesla CEO Elon Musk has been playing around with ideas on how to release other features that take advantage of the fact that the vehicles are now equipped with external speakers.
“Our standard model of cosmology is based on an isotropic universe, one that is the same, statistically, in all directions,” says astrophysicist John Webb at the University of New South Wales about the universal constant which appears inconstant at the outer fringes of the cosmos, it occurs in only one direction…” That standard model itself is built upon Einstein’s theory of gravity, which itself explicitly assumes constancy of the laws of Nature. If such fundamental principles turn out to be only good approximations, the doors are open to some very exciting, new ideas in physics.”
Those looking forward to a day when science’s Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.
In a paper published in Science Advances, scientists from UNSW Sydney reported that four new measurements of light emitted from a quasar 13 billion light years away reaffirm past studies that found tiny variations in the fine structure constant.
An internally built system called Advanced Listening analyzes phone calls, emails, text messages and more, identifying possible compliance violations, systemic issues and opportunities to improve processes, products and customer service.
WASHINGTON — The Blue Origin-led team that is one of three working on lunar lander concepts for NASA’s Artemis program has delivered a full-sized mockup of that lander to the agency for testing by engineers and astronauts.
Blue Origin announced Aug. 20 that its “National Team” has installed an engineering model of the lander in the Space Vehicle Mockup Facility at the Johnson Space Center. The full-sized, but low-fidelity, mockup includes both the descent element, developed by Blue Origin, and ascent element, built by Lockheed Martin, and stands more than 12 meters high.
The companies developed the mockup to allow NASA astronauts and engineers to study the layout of the vehicle, including positioning of various components, and get feedback while the lander is still in an early stage of development.
Oumuamua is an interstellar object that reached the solar system two years back. It showed unusual acceleration in its course across space, which led scientists to believe it could be a probe from another planet or even extraterrestrials. What it is.
Why it’s important
Oumuamua, from the very first day of its discovery, literally perplexed scientists, as it showed an unusual acceleration in its course across space. Now, in a new study report published in The Astrophysical Journal Letters, Loeb and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, has claimed that the hydrogen hypothesis will not work in the real world, which means there could be still a scope that advanced aliens from deep space might have visited the solar system.
It was around two years back that space scientists discovered Oumuamua, an interstellar object that reached the solar system. Oumuamua, from the very first day of its discovery, literally perplexed scientists, as it showed an unusual acceleration in its course across space. After observing this unusual acceleration, Avi Loeb, of the Harvard University suggested that Oumuamua could be an alien probe.
Air conditioners are a convenient way to cool down offices and homes, but they use huge amounts of energy in the process. A team of scientists has been developing an alternative solution for those warm summer months called the Cold Tube, which works by absorbing body heat emitted from a person and can use around half the energy of traditional systems as a result.
The notoriously bad energy efficiency of air conditioners has motivated the development a range of environmentally friendly solutions, from attachments that use water mist to pre-cool the units to solar-powered systems that produce hot water at the same time. In 2018, Richard Branson even launched a US$3 million competition aimed at developing more energy efficient air conditioners.
Similarly, the research team behind the Cold Tube has been investigating next-generation systems that keep people cool in more efficient ways. Made up of scientists from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre, the team took aim at the dehumidification process that is a critical function of today’s air conditioning systems.

Artificial intelligence is proving a potent weapon against the pandemic, enabling researchers to comb through massive data sets to understand the virus and how to combat it. From drug development to immune response, STAT’s Casey Ross will talk to researchers and AI experts about how AI is accelerating a worldwide effort to crack Covid-19’s molecular code.

Most of us are now familiar with apps that track what’s known as our ‘digital biomarkers’. These include the steps, we’ve taken, our heart rate, and our weight. In recent years startups have appeared which can, in a relatively turnkey manner, track our ‘biomedical markers’, such as cholesterol levels, for instance. Few, however, are seeking to combine the two to get a 360-degree view of how our bodies are doing.
Into this gap steps Humanity Inc., which will seek to do exactly that. Founded by two seasoned entrepreneurs, Humanity will combine digital and biomedical biomarkers into a consumer app that will fully launch next year.
Today it announces it’s initial seed fundraise of $2.5m, in a round led by Boston fund One Way Ventures and the legendary and long-time HealthTech Angel investor Esther Dyson, among others.
Honey appears to be a preferable treatment for cough or cold symptoms rather than antibiotics and over-the-counter medicines, according to a new systematic review that’s looked at the results from 14 previous studies — but the conclusions may not be quite so clear-cut as they appear at first.
“Honey is a frequently used lay remedy that is well known to patients,” write the researchers from the University of Oxford in the UK. “It is also cheap, easy to access and has limited harms.”
One particular area of interest is the comparison of honey to antibiotics. With antibiotics often causing side effects and antibiotic resistance on the rise, there are multiple advantages to using honey as an alternative remedy, the authors of the review point out.
