A study found that a low carb, high fat diet can help people with type 2 diabetes lose weight and control glucose levels better than a high carb, low fat diet.
An outbreak of potentially deadly bacteria in at least four states has federal officials on alert. They said parents should be on the lookout for its symptoms, which include flesh-eating disease and toxic shock.
Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and move data faster than today’s electronic-based devices.
“The development of optical interconnects equipped with high-density nanolasers would improve information processing in the data centers that move information across the internet,” said research team leader Myung-Ki Kim from Korea University.
“This could allow streaming of ultra-high-definition movies, enable larger-scale interactive online encounters and games, accelerate the expansion of the Internet of Things and provide the fast connectivity needed for big data analytics.”
The Orion spacecraft will host a trio of astronaut-like payloads that will help NASA learn how best to protect real astronauts during future crewed Artemis missions to the Moon.
Tesla has launched “Tesla Electric” to become an electricity retailer through its Powerwall owners – starting with some markets in Texas.
After gaining experience through its virtual power plants (VPPs), Tesla is taking things a step further with the launch of “Tesla Electric.”
Instead of reacting to specific “events” and providing services to your local electric utilities, like Tesla Powerwall owners have done in VPPs in California, Tesla Electric is actively and automatically buying and selling electricity for Tesla Powerwall owners – providing a buffer against peak prices.
The forecast, first reported by Reuters, represents how some in Silicon Valley are betting the underlying technology will go far beyond splashy and sometimes flawed public demos.
OpenAI was most recently valued at $20 billion in a secondary share sale, one of the sources said. The startup has already inspired rivals and companies building applications atop its generative AI software, which includes the image maker DALL-E 2. OpenAI charges developers licensing its technology about a penny or a little more to generate 20,000 words of text, and about 2 cents to create an image from a written prompt, according to its website.
A spokesperson for OpenAI declined to comment on its financials and strategy. The company, which started releasing commercial products in 2020, has said its mission remains advancing AI safely for humanity.
A gel made of a protein found in human cells can capture particles travelling at supersonic speeds without destroying them on impact, suggesting the material could be used in body armour or for collecting space debris.
No surprises, but confirmation that what we think we should do actually does make a difference. Your brain is really rather amazing. Around 100 billion nerve cells collaborate to keep you nimble and quick-thinking. However, like with the rest of the body, as you age your brain may not be nearly as sharp. You may need to write things down, miss appointments, or have trouble watching TV without straining to understand the dialogue or action.
The speed record for data transmission using a single light source and optical chip has been shattered once again. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.
It’s hard to overstate just how fast 1.84 Pbit/s really is. Your home internet is probably getting a few hundred megabits per second, or if you’re really lucky, you might be on a 1-gigabit or even 10-gigabit connection – but 1 petabit is a million gigabits. It’s more than 20 times faster than ESnet6, the upcoming upgrade to the scientific network used by the likes of NASA.
Even more impressive is the fact this new speed record was set using a single light source and a single optical chip. An infrared laser is beamed into a chip called a frequency comb that splits the light into hundreds of different frequencies, or colors. Data can then be encoded into the light by modulating the amplitude, phase and polarization of each of these frequencies, before recombining them into one beam and transmitting it through optical fiber.
