DATA DELIVERY RATES 4.5 MILLION TIMES FASTER THAN AVERAGE BROADBAND ACHIEVED IN MAJOR FIBER OPTIC BREAKTHROUGH

The fastest data delivery rate ever achieved using specific wavelength bands in fiber optic technology has been reported by an international team of researchers, who say they sent information 4.5 million times faster than the average home broadband will allow.

According to researchers at Aston University in Birmingham, England, who participated in the experiment, a series of new technologies they developed allowed them to successfully transfer data at an astonishing rate of 301 terabits (301,000,000 megabits) per second.

Remarkably, the Aston team says the breakthrough that achieved these impressive data transfer rates used only standard optical fiber.

The team says their breakthrough paves the way toward greener solutions by allowing the transfer of larger amounts of information without the use of additional optical fiber.

Secretive Experiment to Shoot Aerosols Into the Sky Over San Francisco to Increase Cloud Cover

A secretive project conducted from the deck of an aircraft carrier in the San Francisco Bay will shoot trillions of aerosol particles into the sky to increase cloud cover in the name of preventing global warming, and details have been held back to “avoid (a) public backlash.”

The experiment is being dubbed America’s “first outdoor test to limit global warming.”

“The Coastal Atmospheric Aerosol Research and Engagement, or CAARE, project is using specially built sprayers to shoot trillions of sea salt particles into the sky in an effort to increase the density — and reflective capacity — of marine clouds,” reports Scientific American.

“The experiment is taking place, when conditions permit, atop the USS Hornet Sea, Air & Space Museum in Alameda, California, and will run through the end of May, according to a weather modification form the team filed with federal regulators.”

Combating “Hate”: The Trojan Horse For Precrime

Philip K. Dick’s 1956 novella The Minority Report created “precrime,” the clairvoyant foreknowledge of criminal activity as forecast by mutant “precogs.” The book was a dystopian nightmare, but a 2015 Fox television series transforms the story into one in which a precog works with a cop and shows that data is actually effective at predicting future crime.

Canada is trying to enact a precrime law along the lines of the 2015 show, but it is being panned about as much as the television series. Ottawa’s online harms bill includes a provision to impose house arrest on someone who is feared to commit a hate crime in the future. From The Globe and Mail:

The person could be made to wear an electronic tag, if the attorney-general requests it, or ordered by a judge to remain at home, the bill says. Mr. Virani, who is Attorney-General as well as Justice Minister, said it is important that any peace bond be “calibrated carefully,” saying it would have to meet a high threshold to apply.

But he said the new power, which would require the attorney-general’s approval as well as a judge’s, could prove “very, very important” to restrain the behaviour of someone with a track record of hateful behaviour who may be targeting certain people or groups…

People found guilty of posting hate speech could have to pay victims up to $20,000 in compensation. But experts including internet law professor Michael Geist have said even a threat of a civil complaint – with a lower burden of proof than a court of law – and a fine could have a chilling effect on freedom of expression.

While this is a dangerous step in Canada, I also wonder if this is where burgeoning “anti-hate” programs across the US are headed. The Canadian bill would also allow “people to file complaints to the Canadian Human Rights Commission over what they perceive as hate speech online – including, for example, off-colour jokes by comedians.”

There are now programs in multiple US states to do just that –  encourage people to snitch on anyone doing anything perceived as “hateful.”

The 2021 federal COVID-19 Hate Crimes Act began to dole out money to states to help them respond to hate incidents. Oregon now has its Bias Response Hotline to track “bias incidents.”

In December of 2022, New York launched its Hate and Bias Prevention Unit. Maryland, too, has its system – its hate incidents examples include “offensive jokes” and “malicious complaints of smell or noise.”

These Electronic Textiles Don’t Need Chips or Batteries

Sensors, controllers, and other electronic devices embedded in clothing could change the way we interact with computers and with each other. But efforts to turn t-shirts into electronic devices have been hampered by the need to power them with bulky batteries and process their data using stiff circuit boards.

Research published today in Science shows that it doesn’t have to be that way. Textiles woven from high-tech layered fibers couple with the body to scavenge electromagnetic energy from the environment—batteries not included. The textiles can also act as simple sensors that are easy to read by eye, or they can beam out a wireless signal. The research team behind the fibers includes Chengyi Hou, Hongzhi Wang, and Qinghong Zhang, who are in the college of materials science and engineering at Donghua University in Shanghai.

The group has demonstrated these smart fibers in a variety of applications. They’ve made a carpet that senses people’s footsteps, a textile-based game controller, a wearable 644-pixel display, and a textile keyboard that can be used to write messages to put on the display.

“INTELLIGENT LIQUID” CREATED BY HARVARD SCIENTISTS REPRESENTS STRANGE “NEW CLASS OF FLUID”

Harvard researchers say they have developed a programmable metafluid they are calling an ‘intelligent liquid’  that contains tunable springiness, adjustable optical properties, variable viscosity, and even the seemingly magical ability to shift between a Newtonian and non-Newtonian fluid.

The team’s exact formula is still a secret as they explore potential commercial applications. However, the researchers believe their intelligent liquid could be used in anything from programmable robots to intelligent shock absorbers or even optical devices that can shift between transparent and opaque states.

“We are just scratching the surface of what is possible with this new class of fluid,” said Adel Djellouli, a Research Associate in Materials Science and Mechanical Engineering at Harvard’s John A. Paulson School of Engineering and Applied Sciences (SEAS) and the first author of the paper. “With this one platform, you could do so many different things in so many different fields.”

Scientists Put Tardigrade Proteins Into Human Cells. Here’s What Happened.

Freeze ’em, heat ’em, blast them into empty space; with survival skills unlike any other organism on the planet, those hardy critters known as tardigrades will only come back for more.

While it’s clear their ability to withstand stress is in part due to their ability to turn their insides into gel, the mechanisms behind this act of metabolic preservation haven’t yet been made clear.

A new study led by researchers from the University of Wyoming found that expressing key tardigrade proteins in human cells slowed metabolism, providing critical insights into how these virtually indestructible invertebrates can survive under the most extreme conditions.

The team focused on a particular protein called CAHS D, already known to protect against extreme drying (desiccation). Through a variety of methods, the researchers showed how CAHS D transformed into a gel-like state when under stress, keeping molecules protected and protecting against drying.

“This study provides insight into how tardigrades, and potentially other desiccation-tolerant organisms, survive drying by making use of biomolecular condensation,” write the researchers in their published paper.

“Beyond stress tolerance, our findings provide an avenue for pursuing technologies centered around the induction of biostasis in cells and even whole organisms to slow aging and enhance storage and stability.”

Tardigrades have already shown they can survive hot and cold temperatures and high levels of radiation that would be fatal to human beings, and long periods without any water – normally so essential to life. They can even survive in space.

Previous research has revealed an impressive number of tricks that tardigrades use to stay alive, built up over hundreds of millions of years. Essentially, they’re very good at slowing the processes of life right down with the help of CAHS D, and that could be useful in human cells too.

HOLOGRAPHIC BREAKTHROUGH: SCIENTISTS CREATE FULL-COLOR 3D HOLOGRAPHIC DISPLAYS WITH ORDINARY SMARTPHONE SCREEN

A team of scientists from the University of Tokyo has revealed a major breakthrough that allows them to create realistic 3D holographic displays using an ordinary iPhone screen.

While conventional approaches to holography involve complex and expensive laser emitters that have limited their practical use, the researchers behind this novel approach say their work could lead to dramatic improvements in holographic displays for virtual reality applications, including gaming, training, and even advanced military applications.

3D HOLOGRAPHIC DISPLAYS LIMITED BY COST AND COMPLEXITY

In science fiction, holograms are used for anything from basic communications to advanced military weaponry. In the real world, 3D holographic displays have yet to break through to everyday products and devices. That’s because creating holograms that look real and have significant fidelity requires laser emitters or other advanced pieces of optical equipment. This situation has stymied commercial development, as these components are complex and expensive.

More recently, research scientists were able to create realistic 3D holographic images without lasers by using a white chip-on-board light-emitting diode. Unfortunately, that method required two spatial light modulators to control the wave fronts of the emitted light, adding a prohibitive amount of complexity and cost.

Now, those same scientists say they have created a simpler, more cost-effective way to create realistic-looking 3D holographic displays using only one spatial light modulator and new software algorithms. The result is a simpler and cheaper method for creating holograms that an everyday technology like a smartphone screen can emit.

Korean Fusion Reactor Breaks Record, Staying 7 Times Hotter Than The Sun’s Core

Korea Superconducting Tokamak Advanced Research, or KSTAR, is one of the most advanced test fusion reactors on the planet. Nicknamed the Korean artificial sun, it has now demonstrated sustained fusion temperature for almost a minute and the ability to contain extremely hot plasma for over 100 seconds.

Fusion is what powers stars, but in stars, it happens at lower temperatures than we need to do it here on Earth. That’s because gravity is keeping everything packed together so fusion is more likely to happen. So the temperature required on Earth for a Tokamak system – which is a donut-shaped reactor – is about seven times the temperature at the core of the Sun: 100 million °C (180 million °F).

KSTAR first reached this threshold in 2018 but only for 1.5 seconds. A year later, they were able to keep the plasma that hot for 8 seconds, increasing it to 20 seconds in 2020. The last record was in 2021, when the plasma was kept that hot for half a minute. Since then, the team at the Korea Institute of Fusion Energy (KFE) has upgraded the device by building a new tungsten divertor environment and they have pushed the temperature for longer.

Now, KSTAR can sustain 100 million °C for 48 seconds – and it can keep hot plasma in the high-confinement mode (also known as H-mode) for 102 seconds. The goal is to achieve 300 seconds of burning plasma by the end of 2026. 

“Despite being the first experiment run in the environment of the new tungsten divertors, thorough hardware testing and campaign preparation enabled us to achieve results surpassing those of previous KSTAR records in a short period,” Dr Si-Woo Yoon, Director of the KSTAR Research Center, said in a statement.

“To achieve the ultimate goal of KSTAR operation, we plan to sequentially enhance the performance of heating and current drive devices and also secure the core technologies required for long-pulse high performance plasma operations.”

Facebook let Netflix see user DMs to help them tailor content as part of a close collaboration between the two tech giants, new court documents claims

Facebook‘s parent company Meta allegedly allowed Netflix to peer at its user DMs ‘for nearly a decade’ to help the streaming giant better tailor content for its own users, an explosive lawsuit has alleged. 

Court documents unsealed on March 23 that were filed last April as part of a major anti-trust lawsuit against Meta appear to have exposed the intricate relationship between two of Silicon Valley’s biggest players. 

The class-action lawsuit, filed by two US citizens, Maximilian Klein and Sarah Grabert, alleged Netflix and Facebook ‘enjoyed a special relationship’, with the social media platform giving the streaming site ‘bespoke access’ to user data. 

The two Silicon Valley players also agreed to ‘custom partnerships and integrations that helped supercharge Facebook’s ad targeting and ranking models’ from at least 2011, thanks to the personal relationship between Netflix’s co-founder Reed Hastings and Facebook’s founder Mark Zuckerberg. 

Lawyers alleged that ‘within a month’ of Hastings joining Facebook’s board of directors, the two companies signed an ‘Inbox API’ (Application Programming Interface) agreement that ‘allowed Netflix programmatic access to Facebook’s user’s private message inboxes.’

Major League Baseball’s biometric ticketing collects 6K opening day hits

Fans entered a stadium with biometrics during the opening day of the 2024 Major League Baseball (MLB) season, one of four ballparks to deploy the technology, and the league has high hopes for the touchless access program.

The Washington Nationals added biometric ticketing to their opening day lineup through MLB’s Go-Ahead Entry. The introduction of Go-Ahead Entry allows fans attending Nationals games to use the MLB Ballpark app for touchless entry at gates equipped with dedicated hardware.

Fans using the optional service register their biometrics with a selfie and then use facial authentication to enter at full walking speed through dedicated gates. Four lanes have been deployed at Nationals Park in D.C. Two of those are on the west end of the Park’s center field gates, another in center field, and one more on the first-base side of the stadium.

The rollout in Washington follows trials last year at Citizens Bank Ballpark in Philadelphia last year. Those trials showed the biometric lines moving 68 percent faster, and 2.5 times more people passing through them than the fastest lane using physical or smartphone-based tickets, reports the Fredericksburg Free Press. The Phillies have taken their deployment stadium-wide for the 2024 season.

Prior to that, face biometrics were used for entry to New York Mets games with Wicket technology, and to Cleveland Guardians games with Clear’s technology.

The facial recognition technology for MLB’s Go-Ahead Entry was developed by NEC, according to an April 1 ESPN report.
