A robotic hand constructed by a 16-year-old boy and his father using Lego pieces can effectively grasp and manipulate objects, showcasing functionality akin to natural human hands.

Jared Leppola, a student at Bristol Grammar School in England, began working on this project with his father when he was just 14 years old. Nathan Leppola is affiliated with the University of Bristol.

The device utilizes concepts from leading research institutions like Pisa/IIT SoftHand, yet it is built entirely from readily available components from Lego Mindstorms, a popular series of educational kits designed for creating programmable robots.

“My father is a professor of robotics at the University of Bristol, and I was really inspired by the design of robotic hands,” Jared explains. “This motivated me to pursue it in an educational context using Lego.”

The hand operates using two motors based on tendon mechanics, and each of its four fingers is equipped with three joints. A differential mechanism made of Lego clutch gears connects the fingers, allowing them to move in unison until they contact an object and stop, mimicking human grasping behavior.

Throughout testing, the Lego hand successfully grabbed nine common household items, including plastic cups, bowls, and a stuffed toy weighing 0.8 kilograms.

When one finger is engaged, it fully closes in approximately 0.84 seconds and reopens in about 0.97 seconds. This speed is about half that of the Pisa/IIT SoftHand’s 3D-printed counterpart, which employs metal bearings. In static tests, the Lego hand could withstand loads of 5 Newtons, exert a pushing force of 6 Newtons, and deliver a closing force of 1.8 Newtons. Comparatively, the 3D-printed version can manage loads up to 8 Newtons, push with 7 Newtons, and has a closing force of 2 Newtons.

“You won’t find a better hand,” Nathan states regarding the 3D-printed alternative. “In terms of functionality, the LEGO hands are also considerably larger, with each finger measuring 145 millimeters long and 30 millimeters wide.”

While Lego Mindstorms was discontinued in 2022, Jared noted that the device can still be easily modified with a variety of Lego creations. “The way I designed the motor, you can simply take it out and replace it with a new one,” he explains.

Teen Death by Suicide Allegedly Linked to Months of Encouragement from ChatGPT, Lawsuit Claims

The creators of ChatGPT are shifting their approach to users exhibiting mental and emotional distress following legal action from the family of 16-year-old Adam Lane, who tragically took his own life after months of interactions with the chatbot.

OpenAI recognized that its system could pose “potential risks” and stated it would “implement robust safeguards around sensitive content and perilous behavior” for users under 18.

The $500 million (£37.2 billion) San Francisco-based AI company has also rolled out parental controls, giving parents “the ability to gain insights and influence how teens engage with ChatGPT,” but specifics on the functionality are still pending.

Adam, a California resident, sadly committed suicide in April after what his family’s attorneys described as “a month of encouragement from ChatGPT.” His family is suing OpenAI and its CEO and co-founder, Sam Altman. Altman contends that the version of ChatGPT in use at the time, known as 4O, was “released to the market despite evident safety concerns.”

The teenager had multiple discussions with ChatGPT about suicide methods, including just prior to his death. According to filings in California’s Superior Court for San Francisco County, ChatGPT advised him on the likelihood that his method would be effective.

It also offered assistance in composing suicide notes to his parents.

An OpenAI spokesperson expressed that the company is “deeply saddened by Adam’s passing,” and extended its “deepest condolences to the Lane family during this challenging time,” while reviewing court documents.

Mustafa Suleyman, CEO of Microsoft’s AI division, expressed growing concern last week about the “psychological risks” posed by AI to users. Microsoft defines this as “delusions that emerge or worsen through engaging experiences, delusional thoughts, or immersive dialogues with AI chatbots.”

In a blog post, OpenAI acknowledged that “some safety training in the model may degrade” over lengthy conversations. Allegedly, Adam and ChatGPT exchanged as many as 650 messages daily.

Family attorney Jay Edelson stated on X: “The claims from the Lane family indicate that tragedies like Adam’s are unavoidable. They hope that the safety team at OpenAI will challenge the release of version 4O and that one of the company’s leading safety researchers can provide evidence in the case.” Ilya Sutskever has ceased such practices. The lawsuit alleges that the company prioritized a competitive edge with a new model, boosting its valuation from $86 billion to $300 billion.

OpenAI affirmed that it will “strengthen safety measures for long conversations.”

“As interactions progress, some safety training in the model could degrade,” it stated. “For instance, while ChatGPT might initially direct users to a suicide hotline when their intentions are first mentioned, lengthy exchanges could lead to responses that contradict our safeguards.”

OpenAI provided examples of someone enthusiastically communicating with a model, believing it could function 24 hours a day, as they felt invincible after not sleeping for two nights.

“Today, we may not recognize this as a dangerous or reckless notion, and by exploring it in-depth, we can inadvertently reinforce it. We are working on an update to GPT-5, where ChatGPT will actively ground users in reality. In this context, we clarify that lack of sleep can be harmful and recommend rest before taking action.”

How Platforms Lobby for Exemptions Amid the Ban on Aussie Teen Social Media

The Australian government is rapidly identifying which social media platforms will face restrictions for users under 16.

Social Services Minister Tanya Plibersek stated on Monday that the government “will not be intimidated by the actions of social media giants.” Nevertheless, tech companies are vigorously advocating for exemptions from the law set to take effect in December.

Here’s what social media companies are doing to support their case:


The parent company of Facebook and Instagram has introduced new Instagram teen account settings to signal their commitment to teenage safety on the platform.

Recently, Meta revealed New protections, which aim to enhance direct message security by automatically censoring nude images and implementing blocking features.

Additionally, Meta hosted a “Screen Smart” safety event in Sydney targeted at “Parent Creators,” led by Sarah Harris.

YouTube

YouTube’s approach is even more assertive. Last year, Communications Minister Michelle Roland suggested the platform would be exempt from social media restrictions.

However, last month, the Esafety Commissioner advised the government to reconsider this exemption, citing research indicating that children often encounter harmful materials on YouTube.

Since then, the company has escalated its lobbying efforts, including full-page advertisements claiming YouTube can be used by “everyone,” alongside a letter sent to Communications Minister Anica Wells warning of a potential high court challenge if YouTube is subjected to the ban.

As reported by Guardian Australia last month, Google is hosting its annual showcase this week at the Capitol on Wednesday. There, content creators, including child musicians, who oppose the YouTube ban will likely express their views to politicians.

Last year’s event featured the Wiggles, who met with Roland. This meeting was mentioned in a letter sent to Rowland last year when YouTube’s global CEO Neal Mohan requested the exemption within 48 hours of the promised relief.

Guardian Australia reported last week that YouTube met with Wells this month for an in-person discussion regarding the ban.

TikTok

This month, TikTok is running ads on its platform as well as on Meta channels, promoting educational benefits for teens on vertical video platforms.

“The 1.7m #fishtok video encourages outdoor activities in exchange for screen time,” the advertisement states, acknowledging the government’s assertion that the ban would promote time spent outside. “They are developing culinary skills through cooking videos that have garnered over 13m views,” it continues.

“A third of users visit the STEM feed weekly to foster learning,” another ad claims.

Snapchat

Snapchat emphasizes user safety. In May, Guardian Australia reported on an instance involving an 11-year-old girl who added random users as part of a competition with her friend for high scores on the app.

This month, Snapchat announced a partnership with the Australian Federal Police-led Australian Centre to address child exploitation through a series of educational videos shared by various Australian influencers, along with advertisements advising parents and teens on identifying grooming and sextortion.

“Ensuring safety within the Snapchat community has always been our top priority, and collaborating closely with law enforcement and safety experts is crucial to that effort,” stated Ryan Ferguson, Australia’s Managing Director at Snap.

The platform has also reiterated account settings for users aged 13-17, including default private accounts and chat warnings when communicating with individuals who lack shared friends or are absent from contact lists.

Thus far, the government seems unyielding.

“It is undeniable that young people’s mental health has been adversely affected due to social media engagement, prompting the government’s actions,” Prime Minister Anthony Albanese told ABC insiders on Sunday.

“I will meet again with individuals who have faced tragedy this week… one concern expressed by some social media companies is our leadership on this matter, and we take pride in effectively confronting these threats.”

Review: Lost Records: Bloom & Rage (Tape One) Takes Us Back to the Summer of Riot Grrl in a Clever Teen Thriller

tYears ago, Parisian studios did not effectively create a new subgenre of narrative adventures, with teenage mystery life is strange. Part thriller, some relationship drama, it created an emotional Paean with unwavering friendship, using music, art and friendly characters. After a series of sequels, Nod's Montreal Studios created a new story about teenage relationships, split into two episodes or tapes.

In 1995, the introverted teen Swan faces his last quiet summer in a rural Velvet, Michigan town before his family moved to Vancouver. However, in the parking lot of a local video store, she meets fellow 16-year-old Nora, Autumn, and Kat, and the four girls bond about boredom and frustration with small town life. Soon they are inseparable, hiking in the nearby forest, setting camp fire, and confessing their secrets. Here they form the Bloom & Rage of the riot grrrl band, leading their dreams, desires and fear into fantasies of fame and revenge against silly boys and oppressive parents. However, when their swirling emotions seem to awaken a supernatural being in the forest, something terrible happens and the girls swear each other to the secrets of their lives.




A quiet summer, and… Lost record: Bloom & Rage. Photo: Don't nod

Twenty-seven years later, the group meets again in a rough bar on the outskirts of the town, which holds a special connection to their stories. Fall received an ominous package addressed to their band. Anything in the box could be the horrifying result of that tumultuous summer.

In the typical style of Not Nod, the game captivates interactive scenes and cinematic sequences, controlling the conversation that subtly shapes your relationships and story direction. The story interacts between two timelines that remind you of 2022 and two pivotal summers together in 1995. Sometimes the decision you make at the bar as 43-year-old Swann is renovated into her youthful experience, creating a fascinating ambiguity of causality and memory.




As with how we edit memories, just as it actually happens… Lost Records: Bloom & Rage. Photo: Don't nod

Certainly, this game is about how we create and edit memories, just as we do what actually happens to girls. Swann is an avid filmmaker, and 1990s video cameras are with you throughout the game. You can always press the appropriate trigger and see the world through the camcorder lens. In the main story, we use it to shoot a band's music video, but you can record it at any time. This feature is incentivized by a bunch of theme checklists. Record 10 different birds, or 5 ruined playground rides, or graffiti snatches. But you can also capture your own scenes from and around town, record friends casually, and build sequences of themes that can be stored and edited. The interface recalls games like No Man's Sky and Marvel's Spider-Man, where shooting objects are practical gameplay components, but here the camcorder is also a factor of recollection and nostalgia. At the same time, we ask an interesting question about how the role of a player, both as a gamer and a cinematographer, relates to the protagonist, which we embodies in the game.

It's not the only clever trick the game plays in formats and conventions. For example, the dialogue system is specially designed to capture the dynamic energy and chaos of excitatory groups. Options and responses vary depending on who you are watching while you are speaking, characters screaming at each other and comments are lost in the noise. Sometimes you can time out the options in the dialog and choose not to say anything. In some great moments, this mechanic captures the desperate improvisational nature of a teen relationship, moments of wobbling or fleeting eye contact with one comment all day long.

You may find the dialogue to be robust and overly listened, and the sense of authenticity is increased. Those who have played Life Is Strange also see many similarities with the game, especially between Swann and Max Caulfield.

But like its predecessor, Lost Records stunningly captures the way in which seemingly insignificant moments are billed in meaning in younger adults. There's a picnic by the lake, then there's a game of truth or a crackle with absolute strength. The 90s setting is well supported with support with spot-on-contemporary references, from grunge band mixtapes to video players and trawldolls.

In the background, there is subtly a hint of the mystery at the heart of the game, and there is much to expect from the second part. Mainly, it's the character and its vulnerable relationship that sticks to you. Three days after finishing the game, I'm still thinking about them. Unless you simply refuse to indulge in emotional young adult drama, you will be there too.

Lost Records: Bloom & Rage (Tape 1), now out. £59.99
