Using a three-layer opto-electronic neural network, direct, clock-less sub-nanosecond image classification on a silicon photonics chip is demonstrated, achieving a classification time comparable with a single clock cycle of state-of-the-art digital implementations.
Interesting news:
Trump launched the Artemis program which aimed to land astronauts on the Moon again. The interesting news is that Biden has continued this program instead of deciding on some different goal. First, Biden awarded the Artemis Human Landing System to SpaceX’s Starship and now his administration has made another big move.
NASA had spent over $400 million over the past decade trying to create spacesuits for a new Moon landing without much success. Instead of spending more money, they have now shut down this program and have awarded big bucks to two competing companies to finish this program. One of these companies is Axiom Space which is also well into the process of creating a replacement for the ISS. The last interesting Axiom Space move is that they flew four private astronauts to the ISS less than two months ago, using Crew Dragon. (And have much more lined up for the future.)
We knew there was always a transition to industry in our future.
Its called the Omega 1 and it is a rotary engine with no seals, barely any moving parts, and almost no losses in the combustion cycle. With a traditional internal combustion engine you lose stacks of energy through heat and friction, well with this new engine by Astron Aerospace. They aim to eliminate nearly all the losses associated with internal combustion.

Marketing and the need for data rules
Legislators and decision-makers worldwide have also been active in regulating data although it’s almost impossible to keep pace with change in many places. The genuine exploitation of data requires rules and regulations, as growth always increases the potential for misuse. The task of technology companies is to build data pipelines that ensure the trust and security of AI and analytics.
Data is the new currency for businesses, and the overwhelming growth rate of it can be intimidating. The key challenge is to harness data in a way that benefits both marketers and consumers who produce it. And in doing this, manage the “big data” in an ethically correct and consumer-friendly way. Luckily, there are many great services for analyzing data, effective regulation to protect consumers’ rights and a never-ending supply of information at our hands to make better products and services. The key for businesses is to embrace these technologies so that they can avoid sinking in their own data.
Supplementing your diet with the sea organisms Ascidiacea, also known as sea squirts, reverses some of the main signs of aging, according to a new study using an animal model.
While the Fountain of Youth, the mythical spring that restores youth to anyone who bathes in it or drinks its waters, is clearly fantasy, scientists are hard at work looking for ways to combat aging. Some of these scientists just had a breakthrough: they discovered that supplementing a diet with sea squirts, reverses some of the main signs of aging. While more research is needed to verify the effect in humans, as the study was conducted using mice, the findings are very promising.
If you’ve ever glanced in the mirror and seen greying hair and wrinkles, or if you’ve forgotten the name of a close friend, you may desire a medication that might halt or even reverse the effects of aging.
A study reveals one of the reasons why neurons die in Parkinson’s patients
According to World Health Organization (WHO) estimates, around 7 million individuals worldwide suffer from Parkinson’s disease. Although the origins of this neurodegenerative disorder are not entirely understood, it is known that many of its symptoms are caused by the death of neurons that create dopamine.
A study conducted in mice by a research team at the University of Cordoba has uncovered one of the causes of this neuronal loss: the key resides in the protein called DJ1, whose association with Parkinson’s disease has previously been established, but its specific role was unknown until now.
Discovering and tracking asteroids is critical for planetary defense against killer asteroid impacts. The detailed astronomical data associated with it is also useful for providing new insights for astronomers. Helping with this task is a new algorithm called THOR, which has now proven to be capable of finding asteroids. It has been running on the Asteroid Institute’s cloud-based astrodynamics platform for identifying and tracking asteroids.
The Global Exploration Strategy is a blueprint for understanding space policy today.
15 years ago, the Global Exploration Strategy set out the space policy agenda on course to put humans back on the Moon as soon as possible.
Meta Platforms Inc.’s Sheryl Sandberg, who became one of the most recognized figures in global business after helping Facebook transform from a startup into a multibillion-dollar advertising powerhouse, is stepping down as chief operating officer.
Sandberg, 52, will remain on the board of Meta, the parent company of Facebook, Instagram and WhatsApp, according to a post on the social network Wednesday. Javier Olivan, who has led the company’s growth efforts for years, will take Sandberg’s place as COO when she formally leaves in the fall.

**Who will be liable** for harmful speech generated by large language models? As advanced AIs such as OpenAI’s GPT-3 are being cheered for impressive breakthroughs in natural language processing and generation — and all sorts of (productive) applications for the tech are envisaged from slicker copywriting to more capable customer service chatbots — the risks of such powerful text-generating tools inadvertently automating abuse and spreading smears can’t be ignored. Nor can the risk of bad actors intentionally weaponizing the tech to spread chaos, scale harm and watch the world burn.
Indeed, OpenAI is concerned enough about the risks of its models going “totally off the rails,” as its documentation puts it at one point (in reference to a response example in which an abusive customer input is met with a very troll-esque AI reply), to offer a free content filter that “aims to detect generated text that could be sensitive or unsafe coming from the API” — and to recommend that users don’t return any generated text that the filter deems “unsafe.” (To be clear, its documentation defines “unsafe” to mean “the text contains profane language, prejudiced or hateful language, something that could be NSFW or text that portrays certain groups/people in a harmful manner.”).
But, given the novel nature of the technology, there are no clear legal requirements that content filters must be applied. So OpenAI is either acting out of concern to avoid its models causing generative harms to people — and/or reputational concern — because if the technology gets associated with instant toxicity that could derail development. will be liable for harmful speech generated by large language models?
