The system also allows whole-body teleoperation, enabling simultaneous control of all degrees of freedom, including both arms and the mobile base.
The system builds on Google DeepMind’s Aloha system, emphasizing the importance of mobility and dexterity in the field of robotic learning.
Researchers from Harvard SEAS and Boston University reveal its transformative effects, offering newfound mobility and independence for individuals with this debilitating condition.
The wearable tech successfully eliminates a common symptom called ‘gait freezing’ to restore smooth strides for Parkinson’s disease sufferers.
Researchers claim they have achieved the unachievable – the discovery of a near-room-temperature superconductor.
There’s a new group of scientists who claim to have discovered a near-room-temperature superconductor, a claim that garnered much social media and tech nerds’ attention back in August 2023.
A team of researchers has achieved a milestone by developing lightweight and highly efficient stretchable solar cells for energy generation in electronic gadgets.
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) declare it as the “world’s highest-performing stretchable organic solar cell.”
The development is unique as it utilizes organic material to build the photoactive layer of the solar cell, which turns light into energy.
Chip likely designed for Samsung, Google mixed reality headset.
To delve into the technical specifications, Apple’s Vision Pro boasts an impressive resolution of 11.5 million pixels per eye, more than a 4K TV for each eye, with a total resolution of 23 million pixels.
In comparison, the Quest 3 features a total resolution of 4.6 million pixels per eye, slightly surpassing 2k resolution.
The new Snapdragon XR2 chip supporting 4.3k per eye, translating to a total resolution of 34 million pixels at 90 fps, means a potential alignment of the chip with screens akin to Apple’s Vision Pro.

One of the biggest concerns about EVs is that the batteries will need replacing after a few years, at great expense. After all, your smartphone battery is likely to have seen better days within as little as three years. But a Tesla researcher is getting ready to kick this idea into touch once and for all, after demonstrating batteries that could potentially outlive most human beings.
Tesla enthusiasts are likely to have heard of Jeff Dahn already. He’s a professor at Dalhousie University and has been a research partner with Tesla since 2016. His focus has been to increase the energy density and lifetime of lithium-ion batteries, as well as reducing their cost. Dahn appears to have hit the motherload along with colleagues on his research team. In a paper published in the Journal of the Electrochemical Society, the group claims to have created a battery design that could last 100 years under the right conditions.
Dahn’s paper contrasts cells based on Li[Ni0.5Mn0.3Co0.2]O2 chemistry (“NMC 532”) to LiFePO4. The latter is the “Lithium Iron Phosphate” (aka LFP) chemistry that Tesla is currently using in Chinese-built standard Model 3 cars imported into Europe. The LFP chemistry has lower energy density than more widespread Lithium-Ion alternatives, but is cheaper, more durable, and allegedly safer, too. LFP can last up to 12,000 charge-discharge cycles, so beating it in this regard is no mean feat. Dahn’s NMC 532 cells showed no capacity loss after nearly 2,000 cycles. The paper extrapolates this out to imply a 100-year lifespan (they obviously haven’t been testing the battery that long).
😀 They say we could even regenerate human limbs this way aswell as repair human blood vessels.
Cell tubes, made entirely from a patient’s own cells, are just as elastic as blood vessels but much stronger. Skin cells cultured into lumps are skewered on needles on a base, similar to a Kenzan, a tool used in Japanese flower arrangements, and formed into a tube. The technique, called the Kenzan Method, was made possible by a 3D bioprinter. A clinical trial is underway in Japan to transplant these tubes into humans in place of blood vessels. Studies are being done to apply them to nerves and organs.
