AI Breakthrough Speeds Up Quantum Chemistry

Posted by in categories: chemistry, quantum physics, robotics/AI

Caltech’s OrbNet deep learning tool outperforms state-of-the-art solutions.


Artificial intelligence (AI) machine learning is being applied to help accelerate the complex science of quantum mechanics—the branch of physics that studies matter and light on the subatomic scale. Recently a team of scientists at the California Institute of Technology (Caltech) published a breakthrough study in The Journal of Chemical Physics that unveils a new machine learning tool called OrbNet that can perform quantum chemistry computations 1,000 times faster than existing state-of-the-art solutions.

“We demonstrate the performance of the new method for the prediction of molecular properties, including the total and relative conformer energies for molecules in range of datasets of organic and drug-like molecules,” wrote the researchers.

Home security cams hacked in Singapore, and stolen footage sold on adult websites

Posted by in categories: food, habitats, internet, security

* Unsecured home security cameras hijacked * Stolen images circulate on Discord * Everyone needs to take IoT security more seriously.

In Singapore it’s not at all uncommon today for people to have IP cameras all over their homes.

And, of course, the more people who installed internet-connected cameras throughout their private residences the more you would be considered odd if you hadn’t jumped on the bandwagon, and put cameras in your living room, kitchen, bedroom, sometimes even with a view of even more private areas of your house.

Russian rocket for next space station crew transferred to launch pad

Posted by in category: space

A Russian Soyuz booster arrived at its launch pad on the Kazakh steppe Sunday, the last stop before liftoff Wednesday with a three-person crew bound for the International Space Station.

The Soyuz-2.1a rocket emerged from its assembly building at sunrise Sunday for the railroad trek to pad 31 at the Baikonur Cosmodrome in Kazakhstan. After the Soyuz reached the pad, hydraulic cylinders raised the three-stage rocket vertical and gantry arms folded into position around the launcher.

Tesla update lets you lock Sentry Mode/TeslaCam storage in glovebox

Posted by in categories: robotics/AI, surveillance, transportation

Tesla is updating the interior of the Model 3 to let owners lock their Sentry Mode/TeslaCam storage device in the glovebox.

Sentry Mode is Tesla’s integrated surveillance system inside its vehicles using the Autopilot cameras around the car to record potential vandalism or other incidents.

Tesla owners have to plug a storage device in one of the USB ports in the center console and footage recorded by Sentry Mode and TeslaCam, the automaker’s dashcam feature, will be stored on it.

Challenges for LEO HTS Megaconstelllations: Terrestrial Networks Integration

Posted by in categories: government, internet, satellites

Satellite communication has been serving the terrestrial network as a complementor rather than a competitor for a considerable time. The best use-case scenario is the cellular backhaul over VSAT (Very Small Aperture Terminal) to connect remotely installed BTS (Base Transceiver Station) of a cellular network through a geostationary satellite to the respective BSC (Base Station Controller) and ultimately the core network. This technology enabled MNOs (Mobile Network Operators) to increase their subscribers base in remote communities which could not be connected to their network grid through Microwave or Fibre transmission. Similar network architecture, commonly known as bent-pipe and FSS (Fixed Satellite Service), has been used by other networks requirements of ISP (Internet Service Providers), Government, Corporate, Oil & Gas, Mining sectors, where the DCE (Data Communication Equipment) and DTE (Data Terminal Equipment) are replaced from BTS and BSC to networking switches and routers.

However, all these communications are struggling to keep at par with development at terrestrial networks, and the main reason is staggering latency of around 530 milliseconds for a roundtrip of a message through the satellites at an altitude of around 37,000 kilometres, which is a big challenge for Industry 4.0 technologies. The arrival of the planned NGSO mega constellation appears to address the problem through claimed significantly lower latency of around 4 milliseconds, which is at par with fibre optics.

The integration of the networks of mega constellations with those on the ground is a complicated situation with multiple dynamics to analyse. Let us have a brief look at 4G LTE and 5G NR technology and analyse the integration for both backhaul and fronthaul interfaces through NGSO satellites with the core networks.

‘Universal law of touch’ could help make VR indistinguishable from reality

Posted by in categories: Elon Musk, mathematics, virtual reality

The ‘Universal law of touch’ theory was created by researchers at the University of Birmingham, who used mathematical modelling of touch receptors in humans and other animal species. By applying the mathematics of earthquakes to model how vibrations travel through the skin, the team discovered that vibration receptors beneath the skin respond to Rayleigh waves in the same way regardless of age, gender, or even species.


Breakthrough appears to support Elon Musk’s claim we are living in a simulation.

Replacing functional groups with a gold electrode to control reactivity of a molecule

Posted by in categories: chemistry, particle physics

A team of researchers affiliated with several institutions in the Republic of Korea has found that it is possible to replace chemical functional groups with a gold electrode to control the reactivity of a molecule. In their paper published in the journal Science, the group describes attaching target molecules to a gold electrode to change the properties of immobilized molecules and how their technique performed when used to rate changes in the hydrolysis of certain esters.

In chemistry, are assortments of atoms that together work to attach carbon skeletons in . All organic have their own unique functional groups, which play an important role in the formation of molecules. Functional groups can also donate or take away electrons when one molecule comes into contact with another, which is how many occur.

Chemists have found that they can tinker with functional groups to speed up or slow down reactions to suit their needs, and because of that, functional groups play an important role in chemical synthesis. Unfortunately, developing reactions to produce desired products using functional groups has proven to be slow and difficult work. In this new effort, the researchers have found a way to replace the use of functional groups with a gold electrode to make the work easier. They simply attached molecules to a gold electrode and turned on the electricity. The technique allowed for more control over reactions by varying the amount of electricity supplied to the electrode. In such a capacity, the electrode was able to work as a “universal functional group” to inhibit or propel reactions when the researchers manipulated the amount of electricity applied to the electrode.

Putting a RED Cinema Camera on a 100mph First-Person Racing Drone

Posted by in categories: drones, electronics

As drones become better and better at everything they do, it’s only natural photographers and videographers alike start pushing the boundaries of what’s possible. This particular boundary push is not for the faint of heart, however. I’m reasonably new to the drone world. While I’d been keen to dip a toe for a long time, I had been waiting for commercial applications to justify the acquisition. Thankfully, I found a window and jumped right through it.
