The smartphone app Replika lets users create chatbots, powered by machine learning, that can carry on almost-coherent text conversations. Technically, the chatbots can serve as something approximating a friend or mentor, but the app’s breakout success has resulted from letting users create on-demand romantic and sexual partners — a vaguely dystopian feature that’s inspired an endless series of provocative headlines.

Replika has also picked up a significant following on Reddit, where members post interactions with chatbots created on the app. A grisly trend has emerged there: users who create AI partners, act abusively toward them, and post the toxic interactions online.

What if plants could tell us when pests are attacking them, or they’re too dry, or they need more fertilizer. One startup is gene engineering farm plants so they can communicate in in fluorescent colors. The result: a farmer’s phone, drone, or even satellite imagery can reveal what is happening in hundreds of acres of fields …

That leads to better food, fewer crop failures, and more revenue for farmers.

In this TechFirst with John Koetsier we meet Shely Aronov, CEO and founder at InnerPlant, and chat about what plants say, and how farmers can understand their messages.

Miniaturized near-infrared sensor that could fit in a smartphone can analyze the chemical content of milk and plastics.

A TU/e research group has developed a new near-infrared sensor that is easy to make, comparable in size to sensors in smartphones, and ready for immediate use in industrial process monitoring and agriculture. This breakthrough has just been published in Nature Communications.

The human eye is a marvelous sensor. Using three different types of photoreceptor cone cells that convert visible light into signals for different colors, the eye gives essential information about the world around us.

On Tuesday, January 4, Panasonic announced that Redwood Materials would start supplying copper foil to its battery production facility in Giga Nevada. The Japanese tech giant announced the news during the 2022 CES tech trade show.

“Our work together to establish a domestic circular supply chain for batteries is an important step in realizing the full opportunity that EVs have to shape a much more sustainable world,” said Allan Swan, the President of Panasonic Energy of North America, at the latest CES tech trade show.

Redwood Materials, which former Tesla CTO JB Straubel founded, will be supplying Panasonic with copper foil made from recycled materials. The company recycles scripts from discarded electronics like cell phone batteries, laptops, power tools, and even scooters and electric bicycles. Redwood extracts materials like cobalt, nickel, and lithium, which are usually mined, from discarded electronics.

Athletes headed to the Beijing Olympic Winter Games are making final travel preparations, including keeping in line with China’s health measures on the “My 2022″ smartphone app. However, inadequate encryption measures within the app can leave Olympians, journalists and sports officials vulnerable to hackers, privacy breaches, and surveillance, according to a cybersecurity report by the Citizen Lab obtained exclusively by DW. Additionally, the IT forensic specialists found that the app includes a censorship keyword list. The findings come as international concern over digital safety at the Games mounts. Germany, Australia, UK and US have urged their athletes and National Olympic Committees to leave their personal phones and laptops behind and to travel with special devices over fears of digital espionage. The Dutch Olympic Committee outright banned its athletes from bringing personal phones and laptops due to surveillance concerns.

In the Olympic Playbook for athletes and team officials, the International Olympic Committee states that the “My 2022″ app is “in accordance with international standards and Chinese law.” But based on its findings, Citizen Lab concludes that the insecure transmission of personal information “may constitute a direct violation of China’s privacy laws.” This is because China’s data protection laws require that a person’s health and medical records held digitally be transmitted and stored in an encrypted manner. Citizen Lab’s findings also raise questions concerning two Western tech giants that carry the “My 2022″ app: Apple and Google. “Both Apple’s and Google’s policies forbid apps to transmit sensitive data without proper encryption, so Apple and Google will need to determine whether the app’s unresolved vulnerabilities warrant delisting,” Citizen Lab’s Knockel told DW. The Beijing Organizing Committee has stood by its app, however, saying it “passed the examination” of international mobile application markets such as Google, Apple and Samsung.“We have taken measures such as personal information encryption in the app to ensure privacy security,” the committee said Monday to Xinhua News Agency.

The Winter Games, which kicks off on February 4, marks the second Olympic Games during the COVID-19 pandemic. Just as at the Tokyo Summer Games, tracking athletes’ health is required. According to the official Playbook of the International Olympic Committee (IOC), athletes, coaches, reporters and sports officials, as well as thousands of local staff, are required to put their information into either the “My 2022″ smartphone app or website. The app, which was developed in China, is designed to monitor the health of all attendees and staff as well as trace possible COVID-19 infections. Passport data and flight information must be entered into the app. Sensitive medical information related to possible COVID-19 symptoms are also required, such as whether a person had a fever, fatigue, headaches, a dry cough, diarrhea or a sore throat. Those coming from abroad must start entering health data 14 days before arriving in the country. Many countries use a contact tracing app to help combat the pandemic. But “My 2022″ combines contact tracing with other services: It regulates access to events, acts as a visitor’s guide with information on sporting venues and tourist services, as well as providing chat functions (text and audio), news feeds and file transfers.

Apple’s digital car key feature might soon be useful for unlocking more than a handful of BMW models. In his latest newsletter, Bloomberg’s Mark Gurman claimed Hyundai and its upscale Genesis badge will support Apple CarKey “by the summer.” It’s not certain which models would provide the option, but it’s notable that some trim levels of the Ioniq 5 and other Hyundai cars include NFC for a (currently proprietary) digital key.

While remote lock controls have been available through smartphones for a while, CarKey (and its Android equivalent) treats the phone more like a physical key. You just have to bring your phone or Apple Watch to the door handle to unlock it, and you can even place your phone in a given area to start the car. People with ultra-wideband iPhones (such as the iPhone 11 and newer) can even leave their phone in their pocket when opening and starting the vehicle.

If the leak is accurate, Apple’s move could significantly expand the audience for digital car keys — you wouldn’t need to shop from one high-end marque to even consider it. A deal would also suggest the tussle over a possible EV collaboration wasn’t enough to deter Apple and Hyundai from exploring a CarKey team-up.

Researchers at University College London (UCL), Universidade de Santiago de Compostela (USC) and biopharma firm FabRx, have managed to convert an everyday smartphone into an on-demand personalized drug 3D printer.

Using the visible light created by a mobile phone screen, the modified M3DIMAKER LUX system has already proven capable of 3D printing blood-thinning tablets in specific shapes, sizes and dosages. Operable via a user-friendly app, it’s hoped that with further R&D, the team’s machine could be deployed in future by those living in isolated areas, under the remote supervision of GPs to ensure patient safety.

“This novel system would help people who need precise dosages that differ from how a medication is typically sold, as well as people whose required dosage may change regularly,” said the study’s lead author Xiaoyan Xu. “The tablet’s shape and size are also customizable, which enables flexibility in the rate at which the medication gets released into the bloodstream.”

Catherine Labadia, an archaeologist at the State Historic Preservation Office, was on vacation when the first text came in from fellow archaeologist David Leslie. The picture on her phone was of a channel flake, a stone remnant associated with the creation of spear points used by Paleoindians, the first humans known to enter the region more than 10,000 years ago. “I responded, ‘Is this what I think it is?’” “It most definitely is,” texted back Leslie, who was on site at the Avon excavation with Storrs-based Archaeological and Historical Services (AHS). “It was all mind-blowing emojis after that,” Labadia says.

But that first picture was just the beginning. By the time the excavation on Old Farms Road was completed after a whirlwind three months in the winter of 2019, the AHS team had uncovered 15,000 Paleoindian artifacts and 27 cultural features. Prior to this dig, according to Leslie, only 10–15 cultural features — non-movable items such as hearths and posts that can provide behavioral and environmental insights — had been found in all of New England.

The site is significant for more than the quantity and types of artifacts and features found. Early analyses are already changing the way archaeologists think of the Paleoindian period, an epoch spanning from about 13,000 to 10,000 years ago of which little is known due to relatively scant archaeological evidence. The forests of that time, for instance, were likely made up of more diverse species of trees than previously thought. And that opens up new interpretations for what Paleoindians ate. Remains found at the excavation also suggest — for the first time — that Paleoindians and mastodons might have overlapped in the region.

A team of researchers at the Institute of Computer Science and Random Systems has built a non-software-based virus detection system using a Raspberry Pi, an H-field probe and an oscilloscope to detect electromagnetic wave signatures of multiple types of viruses. The team presented its system and test results at last month’s ACM Machinery’s Annual Computer Security Applications Conference and published a paper describing their system on ACM’s Research Article page.

The idea behind the new system is that running software generates electromagnetic waves. And each piece of software generates its own unique wave patterns due to the way the software executes its code. The researchers took advantage of this knowledge and began using an H-field probe to capture wave patterns of known computer viruses running on various devices and viewed the results on an oscilloscope. They saw oscilloscope patterns that were unique to individual viruses as they were running. The researchers used that information to program a Raspberry Pi to identify data from the other two devices to recognize known virus wave patterns, using the system as a virus detector. To determine if a virus is running on a computer, IoT device or smartphone, a user places the H-field probe close enough to the device to read the electromagnetic waves that are generated. The Raspberry Pi then reports on whether it found any viruses, and if so, which ones.
