Researchers discover how music could be used to trigger a deadly pathogen release

Posted by in categories: biotech/medical, computing, media & arts, mobile phones, security

Researchers at the University of California, Irvine have discovered that the safe operation of a negative pressure room—a space in a hospital or biological research laboratory designed to protect outside areas from exposure to deadly pathogens—can be disrupted by an attacker armed with little more than a smartphone.

According to UCI cyber-physical systems security experts, who shared their findings with attendees at the Association for Computing Machinery’s recent Conference on Computer and Communications Security in Los Angeles, mechanisms that control airflow in and out of biocontainment facilities can be tricked into functioning irregularly by a sound of a particular frequency, possibly tucked surreptitiously into a popular song.

“Someone could play a piece of music loaded on their smartphone or get it to transmit from a television or other audio device in or near a negative room,” said senior co-author Mohammad Al Faruque, UCI professor of electrical engineering and computer science. “If that music is embedded with a tone that matches the of the pressure controls of one of these spaces, it could cause a malfunction and a leak of deadly microbes.”

Engineers designed a new nanoscale 3D printing material that can be printed at a speed of 100 mm/s

Posted by in categories: 3D printing, drones, energy, nanotechnology, satellites

It’s all thanks to nanoclusters.

A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronicsAn improved lightweight, a protective lattice that can absorb twice as much energy as previous materials of a similar density has been developed by engineers for nanoscale 3D printing.

According to the study led by Stanford University, a nanoscale 3D printing material, which creates structures that are a fraction of the width of a human hair, will enable to print of materials that are available for use, especially when printing at very small scales.

Mathematical models shed new light on the interior of neutron stars

Posted by in categories: cosmology, mathematics, physics

“Neutron stars apparently behave a bit like chocolate pralines”.

Neutron stars were first discovered more than 60 years ago, but very little is known about the interior of neutron stars, the incredibly compact cores of dead stars.

According to their findings, a press statement reveals, they bear a surprising resemblance to chocolate pralines.

Can The Metaverse Fix Our Generosity Crisis?

Posted by in categories: education, innovation

A disturbing documentary titled Childhood 2.

Spoiler alert: It’s worse than you could imagine.


Returning to Childhood 2.0 and so many discouraging—okay—depressing documentaries from the past few years (The Great Hack, Requiem for The American Dream, The Social Dilemma, etc.), it’s tempting to throw up our hands. To surrender to disillusionment. Even nihilism.

Notion Releases Alpha of Generative AI Copywriting Tool

Posted by in category: robotics/AI

Notion wants to write you a poem. The popular note-taking and database app has released Notion AI in private alpha today, becoming the latest consumer technology company to incorporate generative artificial intelligence.

In response to a request from a user, the new functionality can create functional scaffolds for blogs, social media posts, and other assets. A meeting agenda, press release, brainstorm, or poem can also be generated by Notion AI.

Aside from that, Notion AI can speed up the research and editing process for writers. The AI can, for example, analyze and summarize articles, pulling out critical points and action items.

Defiant Sam Bankman-Fried declares he has ‘2 weeks to raise $8b’ after FTX bankruptcy

Posted by in categories: cryptocurrencies, futurism

‘I was one of the world’s greatest fundraisers; now I’m the fallen wreckage of one.’

Sam Bankman-Fried (SBF), the former chief executive of the bankrupt cryptocurrency exchange Futures Exchange (FTX), has asserted that FTX is still solvent and plans to raise money even while the formal bankruptcy procedure is underway.

“I have 2 weeks to raise $8 billion; that’s basically all that matters for the rest [of] my life.” he wrote, responding to a question about his plans.

Early meteorites brought enough water to Mars to create a global ocean

Posted by in categories: chemistry, space

The meteorites that bombarded Mars during the early days of the inner solar system may have carried enough water to create a 300-metre-deep ocean on the planet.

Martin Bizzarro at the University of Copenhagen in Denmark and his colleagues have analysed the concentration of a rare chromium isotope, known as chromium-54, in samples of meteorites that have come to Earth from Mars to estimate how much water was deposited on the Red Planet by asteroids.

The uppermost layer of Mars contains the chemical signatures of carbonaceous, or C-type, meteorites that bombarded it as its crust solidified some 4.5 billion years ago.

3D-printing microrobots with multiple component modules inside a microfluidic chip

Posted by in categories: 3D printing, biotech/medical, chemistry, nanotechnology, robotics/AI

Scientists from the Department of Mechanical Engineering at Osaka University introduced a method for manufacturing complex microrobots driven by chemical energy using in situ integration. By 3D-printing and assembling the mechanical structures and actuators of microrobots inside a microfluidic chip, the resulting microrobots were able to perform desired functions, like moving or grasping. This work may help realize the vision of microsurgery performed by autonomous robots.

As medical technology advances, increasingly complicated surgeries that were once considered impossible have become reality. However, we are still far away from a promised future in which microrobots coursing through a patient’s body can perform procedures, such as microsurgery or cancer cell elimination.
