Uganda: Filters turn dirty lake water into drinking water | Global Ideas

Posted by in categories: innovation, sustainability

Innovation in Uganda.


Access to clean water may be a right, but it’s often hard to come by. Contaminated water kills. Henry Othieno and Saudah Birungi have developed eco-friendly filters for use in schools and homes. They turn dirty lake water into drinking water.

MIT’s “Programmable Matter” Technique: A Zap of Light Switches Objects’ Colors and Patterns

Posted by in category: transportation

“Programmable matter” technique could enable product designers to churn out prototypes with ease.

When was the last time you repainted your car? Redesigned your coffee mug collection? Gave your shoes a colorful facelift?

You likely answered: never, never, and never. You might consider these arduous tasks not worth the effort. But a new color-shifting “programmable matter” system could change that with a zap of light.

LUMILOR — Electric Paint That Lights Up at The Flip of a Switch

Posted by in category: energy

LumiLor is an electroluminescent coating system which allows anything coated with it to function as a light. Electroluminescence simply means that an object is capable of emitting light when an electrical current passes through it.

The lifespan of LumiLor is dependent on how much power is applied and the native LumiLor color used. More power equals brighter light but a shorter half life.

Spectre Strikes Back: New Hacking Vulnerability Affecting Billions of Computers Worldwide

Posted by in category: cybercrime/malcode

Computing experts thought they had developed adequate security patches after the major worldwide Spectre flaw of 2018, but UVA’s discovery shows processors are open to hackers again.

In 2018, industry and academic researchers revealed a potentially devastating hardware flaw that made computers and other devices worldwide vulnerable to attack.

Researchers named the vulnerability Spectre because the flaw was built into modern computer processors that get their speed from a technique called “speculative execution,” in which the processor predicts instructions it might end up executing and preps by following the predicted path to pull the instructions from memory. A Spectre attack tricks the processor into executing instructions along the wrong path. Even though the processor recovers and correctly completes its task, hackers can access confidential data while the processor is heading the wrong way.

Quantum Computing and Reinforcement Learning Are Joining Forces to Make Faster AI

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

Recently, scientists designed an AI agent that learns 60% faster than its peers by combining quantum and classical computing. 📈


This week, an international collaboration led by Dr. Philip Walther at the University of Vienna took the “classic” concept of reinforcement learning and gave it a quantum spin. They designed a hybrid AI that relies on both quantum and run-of-the-mill classic computing, and showed that—thanks to quantum quirkiness—it could simultaneously screen a handful of different ways to solve a problem.

The result is a reinforcement learning AI that learned over 60 percent faster than its non-quantum-enabled peers. This is one of the first tests that shows adding quantum computing can speed up the actual learning process of an AI agent, the authors explained.

First genetically modified mosquitoes released in the United States

Posted by in categories: biotech/medical, genetics

After a decade of fighting for regulatory approval and public acceptance, a biotechnology firm has released genetically engineered mosquitoes into the open air in the United States for the first time. The experiment, launched this week in the Florida Keys — over the objections of some local critics — tests a method for suppressing populations of wild Aedes aegypti mosquitoes, which can carry diseases such as Zika, dengue, chikungunya and yellow fever.


Biotech firm Oxitec launches controversial field test of its insects in Florida after years of push-back from residents and regulatory complications.

Gravitational-wave scientists propose new method to refine the Hubble Constant—the expansion and age of the universe

Posted by in categories: physics, space

A team of international scientists, led by the Galician Institute of High Energy Physics (IGFAE) and the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), has proposed a simple and novel method to bring the accuracy of the Hubble constant measurements down to 2% using a single observation of a pair of merging neutron stars.

The universe is in continuous expansion. Because of this, distant objects such as galaxies are moving away from us. In fact, the further away they are, the faster they move. Scientists describe this expansion through a famous number known as the Hubble constant, which tells us how fast objects in the universe recede from us depending on their distance to us. By measuring the Hubble constant in a precise way, we can also determine some of the most fundamental properties of the universe, including its age.

For decades, scientists have measured Hubble’s constant with increasing accuracy, collecting electromagnetic signals emitted throughout the universe but arriving at a challenging result: the two current best measurements give inconsistent results. Since 2015, scientists have tried to tackle this challenge with the science of gravitational waves, ripples in the fabric of space-time that travel at the speed of light. Gravitational waves are generated in the most violent cosmic events and provide a new channel of information about the universe. They’re emitted during the collision of two —the dense cores of collapsed —and can help scientists dig deeper into the Hubble constant mystery.
