Remember Orkut? Its founder wants to bring it back

In a post on X on Thursday, Orkut Büyükkökten, the founder of the eponymous social network, urged users to visit Orkut.com and add their names in support of bringing it back, as well as invite others to join.

Orkut first debuted in 2004 as a side project by Büyükkökten, 51, while he was at Google. The social network went on to become hugely popular in India and Brazil but later lost ground to Facebook. Google eventually shut it down in September 2014, shifting its focus to other platforms, including Google+ and YouTube.

In a letter published on Orkut.com, Büyükkökten criticized how social media has evolved over the past two decades, particularly the growing influence of algorithms and AI-generated content. “Artificial intelligence is extraordinary technology, but it’s dissolving the one premise that made social networking special and worth building: that there was a person on the other side,” he wrote.

The Steel Was Never Real

7 review: how falling walls between science, bodies, and AI are changing everything.

What if the walls between the sciences were never real? 🗄️🔥

After 75 deep dives, Heliox found a hidden pattern: the best answers live in the overlap between disciplines.

In “The Steel Was Never Real,” you’ll hear:

• How a Bayesian model revealed that two identical heart attacks can have completely different biological causes.

Ultrathin mesh harvests energy from human heart cells to generate electricity

A team of engineers led by the University of Massachusetts Amherst has designed an ultrathin, flexible mesh that seamlessly integrates electronics with human cells to provide a continuous, reliable, powerful electrical supply. The study, published in Science Advances, provides a potential solution to one of the most difficult problems in wearable and implantable electronics: how to get rid of batteries.

“Humans have long dreamed of a future where certain electronics can augment our abilities,” says Jun Yao, associate professor in UMass Amherst’s Riccio College of Engineering and the paper’s senior author. One can think of famous examples from science fiction’s cyborgs, but there are also plenty of everyday examples that have nothing to do with Star Trek: pacemakers and implantable defibrillators, for example, or deep brain stimulators, cochlear implants and various health monitors. Every one of these needs a power source.

Unfortunately, batteries—the dominant power source—are bulky and eventually run out of juice, and making them smaller and more flexible reduces the charge they can store.

World’s largest fusion reactor gets final 485-ton vacuum vessel sector

ITER, the world’s largest nuclear fusion reactor, reached a major milestone in its decades-long journey after a European consortium delivered the final vacuum vessel sector on site. The vacuum vessel is also known as the plasma chamber and will be home to fusion reactions while also acting as the first containment barrier for the reactor.

In our bid to move away from fossil fuels, scientists are working to replicate the reactions that occur in stars and release large amounts of carbon-free energy in the process. Called nuclear fusion, the process is considered advantageous over its fission counterpart, since it does not generate large amounts of radioactive waste.

However, nuclear fusion research is still in its infancy, and scientists are working to create reactions that can be sustained for long durations. ITER is the world’s largest nuclear fusion experiment that is working to sustain nuclear fusion reactions inside a tokamak, or donut-shaped, reactor vessel.
