How India’s farmers are using technology to feed more than a billion people

Posted by in categories: biotech/medical, food, internet, mobile phones

Hundreds of millions of people in India depend on farming for their livelihoods, but many of them struggle with losing crops to disease, getting them to market or achieving the right price when they do. Several startups are trying to change that.

Piggybacking on India’s mobile boom, these companies are using smartphones and the internet to help farmers grow, harvest and sell their crops more efficiently. India is self-sufficient in food staples, but faces a constant challenge to feed its population of 1.3 billion and rising. The country accounts for a quarter of the world’s hungry people and is home to over 190 million undernourished people, according to the latest estimates by the United Nations.

“There is a lot of financing and talent which is coming in this space,” says Rikin Gandhi, co-founder and executive director of Digital Green, a social enterprise that began as a research project backed by Microsoft ( MSFT ).

Elon Musk’s Neuralink unveils device to connect your brain to a smartphone

Posted by in categories: Elon Musk, mobile phones, robotics/AI

Neuralink seeks to build a brain-machine interface that would connect human brains with computers. No tests have been performed in humans, but the company hopes to obtain FDA approval and begin human trials in 2020. Musk said the technology essentially provides humans the option of “merging with AI.”

Directed-energy weapon (DEW) full documentary

Posted by in categories: drones, military, mobile phones, particle physics

A directed-energy weapon (DEW) emits highly focused energy, transferring that energy to a target to damage it.

Potential applications of this technology include anti-personnel weapon systems, potential missile defense system, and the disabling of lightly armored vehicles such as cars, drones, watercraft, and electronic devices such as mobile phones.

This “Quantum Battery” Never Loses Its Charge

Posted by in categories: mobile phones, quantum physics

A team of scientists from the universities of Alberta and Toronto have laid out the blueprints for a “quantum battery” that never loses its charge.

To be clear, this battery doesn’t exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough in energy storage.

“The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical electrochemical principles, whereas quantum batteries rely solely on quantum mechanics,” University of Alberta chemist Gabriel Hanna said in a statement.

Pushing quantum photonics

Posted by in categories: computing, mobile phones, quantum physics

Quantum computers use the fundamentals of quantum mechanics to potentially speed up the process of solving complex computations. Suppose you need to perform the task of searching for a specific number in a phone book. A classical computer will search each line of the phone book until it finds a match. A quantum computer could search the entire phone book at the same time by assessing each line simultaneously and return a result much faster.

New supercomputer simulations explore magnetic reconnection and make a surprising discovery

Posted by in categories: cosmology, mobile phones, supercomputing

Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. The process gives rise to auroras, solar flares and geomagnetic storms that can disrupt cell phone service and electric grids on Earth. A major challenge in the study of magnetic reconnection, however, is bridging the gap between these large-scale astrophysical scenarios and small-scale experiments that can be done in a lab.

Researchers have now overcome this barrier through a combination of clever experiments and cutting-edge simulations. In doing so, they have uncovered a previously unknown role for a universal process called the “Biermann battery effect,” which turns out to impact magnetic in unexpected ways.

The Biermann battery effect, a possible seed for the magnetic fields pervading our universe, generates an electric current that produces these fields. The surprise findings, made through , show the effect can play a significant role in the reconnection occurring when the Earth’s magnetosphere interacts with astrophysical plasmas. The effect first generates lines, but then reverses roles and cuts them like scissors slicing a rubber band. The sliced fields then reconnect away from the original reconnection point.

Are You Ready for the Future of Transhumanism?

Posted by in categories: biotech/medical, cyborgs, mobile phones, robotics/AI, transhumanism

Are you ready for the future? A Transhumanist future? One where everyone around you—friends, family, and neighbors—has dipped into the transhumanist punch bowl. A future of contact lenses that see in the dark, endoskeleton attached artificial limbs that lift a half-ton, and brain chip implants that read your thoughts and instantly communicate them to others. Sound crazy? Indeed, it does. Nevertheless, it’s coming soon. Very soon. In fact, much of the technology already exists. Some of it’s being sold commercially at your local superstore or being tested in laboratories right now around the world.

We’ve all heard about driverless test cars on the roads and how doctors in France are replacing people’s hearts with permanent robotic ones, but did you know there’s already a multi-billion dollar market for brain wave reading headsets? Using electroencephalography (EEG) sensors that pick up and monitor brain activity, NeuroSky’s MindWave can attach to Google Glass and allow you to take a picture and post it to Facebook and Twitter just by thinking about it. Other headsets allow you to play video games on your iPhone just with your thoughts too. In fact, well over a year ago now, the first mind-to-mind communication took place. A researcher in India projected a thought to a colleague in France, and using their headsets, they understood each other. Telepathy went from science fiction to reality.

The history of transhumanism—the burgeoning field of science and radical tech used to describe robotic implants, prosthetics, and cyborg-like enhancements in the human being and its experience—has come a long way since scientists began throwing around the term a half century ago. What a difference a generation or two makes. Today a thriving pro-cyborg medical industry is setting the stage for trillion-dollar markets that will remake the human experience. Five million people in America suffer from Alzheimer’s, but a new surgery that involves installing brain implants is showing promise in restoring people’s memory and improving lives. The use of medical and microchip implants, whether in the brain or not, are expected to surge in the coming years. Some experts surmise as many as half of Americans will have implants by 2020. I already have one in my hand. It’s truly a new age for humans.

At Tech’s Leading Edge, Worry About a Concentration of Power

Posted by in categories: internet, mobile phones, robotics/AI

The research scientists’ warnings come amid rising concern about the power of the big tech companies. Most of the focus has been on the current generation of technology — search, online advertising, social media and e-commerce. But the scientists are worried about a barrier to exploring the technological future, when that requires staggering amounts of computing.


Each big step of progress in computing — from mainframe to personal computer to internet to smartphone — has opened opportunities for more people to invent on the digital frontier.

But there is growing concern that trend is being reversed at tech’s new leading edge, artificial intelligence.
