C’est dans le MIT review que j’ai décelé ceci – Analyzing the way you type and scroll can reveal as much as a psychological test. There are about 45 million people in the US alone with a mental illness, and those illnesses and their courses of treatment can vary tremendously. But there is something most of those people have in common: a smartphone. A startup founded in Palo Alto, California, by a trio of doctors, including the former director of the US National Institute of Mental Health, is trying to prove that our obsession with the technology in our pockets can help treat some of today’s most intractable medical problems: depression, schizophrenia, bipolar disorder, post-traumatic stress disorder, and substance abuse. Mindstrong Health is using a smartphone app to collect measures of people’s cognition and emotional health as indicated by how they use their phones. Once a patient installs Mindstrong’s app,…

Dr. Oxman is the founder of a discipline she calls material ecology, which marries the technological advances of computational design, synthetic biology and digital fabrication (otherwise known as 3-D printing) to produce compostable structures, glass objects that vary their optical and structural properties, and garments made from a single piece of silk fabric.

An AI-driven robot hand spent a hundred years teaching itself to rotate a cub AI researchers have demonstrated a self-teaching algorithm that gives a robot hand remarkable new dexterity. The creation: The robotic system, dubbed Dactyl, was developed by researchers at OpenAI. It taught itself to manipulate a cube with uncanny skill by practicing for the equivalent of a hundred years inside a computer simulation (though only a few days in real time). How it works: It uses an off-the-shelf robotic hand from a UK company called Shadow, an ordinary camera, and an algorithm that’s already mastered multiplayer video game, DotA, using the same self-teaching approach. Why it matters: As our own Will Knight explains, the robotic hand is still nowhere near as agile as a human one, and too clumsy to be deployed in a factory or warehouse. Even so, the research shows the potential for machine learning to…

Une action en justice est intentée contre Youtube et Google aux Etats-Unis pour violation de la vie privée des enfants. A coalition of more than 20 consumer advocacy groups is expected to file a complaint with federal officials on Monday claiming that YouTube has been violating a children’s privacy law. The complaint contends that YouTube, a subsidiary of Google, has been collecting and profiting from the personal information of young children on its main site, although the company says the platform is meant only for users 13 and older. The coalition of consumer groups said YouTube failed to comply with the Children’s Online Privacy Protection Act, a federal law that requires companies to obtain consent from parents before collecting data on children younger than 13. The groups are asking for an investigation and penalties from the Federal Trade Commission, which enforces the law. “Google has been continually growing its child-directed…

Hackers stole $172 billion from people in 2017 As many as 978 million people in 20 countries lost money to cybercrime last year, according to a new report by security firm Norton. The individual impact: Norton says that victims lost an average of $142 to hackers in 2017, and that each victim spent almost 24 hours dealing with the fallout. How the US was hit: The report claims that 143 million Americans were affected by cybercrime in 2017, losing a total of $19.4 billion. The big threats: The leading technique used to extort money from consumers was malware—including things like ransomware and cryptojacking. But fraud and password loss were also big hitters. Why it matters: Norton says that people are overconfident about their own cybersecurity chops. It’s a reminder that we should all be more vigilant online.

L’existence de plusieurs vulnérabilités sur des processeurs couramment utilisés a été rendue publique. Il n’y a pas à ce jour d’exploitation avérée de ces failles de sécurité appelées Meltdown et Spectre. Pour autant, le CERT-FR* recommande d’appliquer l’ensemble des mises à jour proposées. Voici quelques clés de compréhension. Qu’est-ce qu’un processeur ? Un processeur est un composant indispensable au fonctionnement des ordinateurs, ordiphones, tablettes (etc.) et des programmes qui y sont installés. Ces processeurs sont construits par plusieurs industriels, notamment INTEL, AMD et ARM et couvrent à eux seuls la grande majorité de nos outils électroniques quotidiens. La couche intermédiaire entre les logiciels et le processeur s’appelle le système d’exploitation (par exemple : Windows, MacOS, iOS, Android, etc.). Que se passe-t-il ? Liées à des défauts de conception de ces processeurs, les failles de sécurité Spectre et Meltdown pourraient, une fois exploitées, accorder un accès non autorisé à de l’information protégée…
