Drops Wear Different “Crowns”

Posted by in category: futurism

A study of drops falling on a thin liquid film finds that splash behavior depends on film thickness—a result that could impact our understanding of stalagmite formation.

A model that can realistically insert humans into images

Posted by in categories: computing, health

The recent advent of generative models, computational tools that can generate new texts or images based on the data they are trained on, opened interesting new possibilities for the creative industries. For example, they allow artists and digital content creators to easily produce realistic media content that integrates elements of different images or videos.

Inspired by these recent advances, researchers at Stanford University, UC Berkeley and Adobe Research have developed a new model that can realistically insert specific humans into different scenes, for instance showing them as they exercise in the gym, watch a sunset on the beach, and so on.

Their proposed architecture, which is based on a class of generative models known as diffusion models, was introduced in a paper pre-published on the arXiv server and set to be presented at the Conference on Computer Vision and Pattern Recognition (CVPR) 2023 in Vancouver this June.

Astronomers explore a recently discovered luminous quasar

Posted by in categories: cosmology, physics

Using various space telescopes, an international team of astronomers have observed a recently detected luminous quasar known as SMSS J114447.77–430859.3, or J1144 for short. Results of the observational campaign, available in the July 2023 edition of Monthly Notices of the Royal Astronomical Society, shed more light on the properties of this source.

Quasars, or quasi-stellar objects (QSOs) are (AGN) of very high luminosity, emitting observable in radio, infrared, visible, ultraviolet and X-ray wavelengths. They are among the brightest and most distant objects in the known universe, and serve as fundamental tools for numerous studies in astrophysics as well as cosmology. For instance, quasars have been used to investigate the large-scale structure of the universe and the era of reionization. They also improved our understanding of the dynamics of supermassive black holes and the intergalactic medium.

J1144 was detected in June 2022 at a redshift of 0.83. It has a bolometric luminosity of about 470 quattuordecillion erg/s, which makes it the most luminous quasar over the last 9 billion years of cosmic history. It is also the optically brightest (unbeamed) quasar at a redshift greater than 0.4.

Whole Brain Emulation

Posted by in categories: existential risks, mapping, neuroscience, robotics/AI

I had an amazing experience at the Foresight Institute’s Whole-Brain Emulation (WBE) Workshop at a venue near Oxford! For more information and a list of participants, see: I had the opportunity to work within a group of some of the most brilliant, ambitious, and visionary people I’ve ever encountered on the quest for recreating the human brain in a computer. We also discussed in depth the existential risks of upcoming artificial superintelligence and how to mitigate these risks, perhaps with the aid of WBE.

My subgroup focused on exploring the challenge of human connectomics (mapping all of the neurons and synapses in the brain).

WBE is a potential technology to generate software intelligence that is human-aligned simply by being based directly on human brains. Generally past discussions have assumed a fairly long timeline to WBE, while past AGI timelines had broad uncertainty. There were also concerns that the neuroscience of WBE might boost AGI capability development without helping safety, although no consensus did develop. Recently many people have updated their AGI timelines towards earlier development, raising safety concerns. That has led some people to consider whether WBE development could be significantly speeded up, producing a differential technology development re-ordering of technology arrival that might lessen the risk of unaligned AGI by the presence of aligned software intelligence.

This wireless ultrasound patch can sense deep tissue vital signs

Posted by in category: biotech/medical

The device can track body signals from tissues as deep as 164 mm for up to twelve hours at a time.

A team of researchers and scientists from the University of California San Diego have developed a stick-on ultrasound patch, also called an ultrasonic system-on-patch (USoP), which a person can wear on the go as the device gives insight on the blood pressure, heart rate, and other physiological signs of the subject wearing it.

As per the press release, the USoP tracks these body signals from tissues as deep as 164 mm for up to twelve hours at a time.

‘Deepfake’ scam in China raises concerns of AI-powered fraud

Posted by in category: robotics/AI

Citizens are concerned about whether implemented rules are sufficient to protect them.

A recently reported scam in China that used ‘deep fake’ technology has raised concerns about the use of artificial intelligence (AI) in conducting fraudulent activities in the country. Discussion on the social media website Weibo about the explosion in the number of AI-powered scans gained more than 120 million views in a day, Reuters.

Over the years, the term ‘deep fakes’ has mainly been associated with celebrities, but as AI tech becomes more mainstream, it has also sparked fears of affecting the commoner.

Spain powered itself with renewable energy for nine straight hours

Posted by in categories: government, solar power, sustainability

The country’s government recently announced a €2 billion fund aimed at tackling its severe drought problem.

Spain hit an impressive renewable energy milestone last week when it was powered solely by renewables for nine hours straight.

Energy generated by solar panels, wind turbines, and hydro energy was able to power mainland Spain from 10 am to 7 pm local time (CEST) on Tuesday, May 16, a report from Spanish newspaper El País reveals.

Chinese Automaker Entering U.S. Market With All-Electric BYD e6

Posted by in categories: sustainability, transportation

Competition in the burgeoning electric vehicle market is heating up. Green car enthusiasts are already salivating at the chance to test-drive the Nissan LEAF and the Chevrolet Volt when they hit dealerships late this year. Now, it seems an underdog has stepped out from the shadows to give these big hitters a real run for their money.

At this year’s Detroit Auto Show, Chinese automaker BYD announced plans to break into the North American auto market by selling their all-electric e6 in the United States by the end of the year.

While Chevy and Nissan don’t have much to worry about in the short-term — initial rollout is currently slated for the Southern California market only — BYD has some pretty lofty goals that could spell trouble over the next few years. Specifically, BYD (which stands for “Build Your Dreams”) plans on becoming no less than the world’s largest automaker by 2025.
