An experiment that solved a 100-year-old mystery posed by Einstein is about to turn back on — and it’s more powerful than ever

Posted by in categories: cosmology, physics

  • Colliding black holes and neutron stars create ripples in spacetime, called gravitational waves. These were “heard” for the first time in September 2015.
  • On Monday, a pair of gravitational-wave detectors called LIGO will turn back on after 6 months of downtime and upgrades.
  • To boost its power, the experiment will now work with a sister machine in Italy called Virgo.
  • Physicists expect the next period of searching for colliding black holes to last a year and be 40% more sensitive than before.

One of the most remarkable experiments in history — a pair of giant machines that listen for ripples in spacetime called gravitational waves — will wake up from a half-year nap on Monday. And it will be about 40% stronger than before.

That experiment is called the Laser Interferometer Gravitational-Wave Observatory (LIGO); it consists of two giant, L-shaped detectors that together solved a 100-year-old mystery posed by Albert Einstein.

This woman’s genetic mutation shields her from pain and anxiety

Posted by in categories: biotech/medical, genetics

Arthritis is usually painful. So is the surgery to fix it, at least in the immediate aftermath. So when a 66-year old woman at Raigmore Hospital in Inverness, Scotland, told doctors that her severely arthritic hand felt fine both before and after her operation, they were suspicious. The joint of her thumb was so severely deteriorated that she could hardly use it—how could that not hurt?

So they sent her to see teams specializing in pain genetics at University College London and the University of Oxford. Those researchers took DNA samples from both her and some of her family members and uncovered her secret: a tiny mutation in a newly-discovered gene. They recently published their results in the British Journal of Anaesthesia.

This minuscule deletion is inside something called a pseudogene, which is a partial copy of a fully functioning gene inserted elsewhere in the genome. Pseudogenes don’t always have a function—sometimes they’re just junk DNA—but some of them have residual functionality leftover from the original gene’s purpose.

Remote-Controlled Insect Ornithopter Developed

Posted by in category: futurism

Aeronautical engineer Edwin Van Ruymbeke has developed a remote-controlled insect ornithopter called MetaFly.

Capable of reaching a top speed of 18 km/h (11 mph) and a maximum range of 100 metres (328 ft), the wings are flapped using a mechanical coreless motor and an aluminum heat sink that is powered by a rechargeable lithium-polymer battery.

Weighing 10 grams (0.35 oz), MetaFly measures 19 cm long (7.5 in) with a 29-cm (11.4-in) wingspan. The patented wings are made from carbon fibre, liquid crystal polymer and oriented polypropylene.

The Human, Smart and Sustainable Future of Cities

Posted by in categories: architecture, big data, environmental, transportation

The city of the future is a symbol of progress. The sci-fi vision of the future city with sleek skyscrapers and flying cars, however, has given way to a more plausible, human, practical, and green vision of tomorrow’s smart city. Whilst smart city visions differ, at their heart is the notion that in the coming decades, the planet’s most heavily concentrated populations will occupy city environments where a digital blanket of sensors, devices and cloud connected data is being weaved together to build and enhance the city living experience for all. In this context, smart architecture must encompass all the key elements of what enable city ecosystems to function effectively. This encompasses everything from the design of infrastructure, workspaces, leisure, retail, and domestic homes to traffic control, environmental protection, and the management of energy, sanitation, healthcare, security, and a building’s eco-footprint.

The world’s premier cities and architects are competing to design and build highly interconnected smart environments where people, government and business operate in symbiosis with spectacular exponentially improving technologies such as big data, the Internet of Things (IoT), cloud computing, hyperconnectivity, artificial intelligence (AI), robots, drones, autonomous green vehicles, 3D/4D printing, smart materials, and renewable energy. The architectural promise of future smart cities is to harmonize the benefits of these key disruptive technologies for society and provide a high quality of life by design. Some have already implemented smart city architecture and, as the concepts, experiences and success stories spread, the pursuit of smart will become a key driver in the evolving future of cities as communities and economic centres. Here we explore some of the critical trends, visions, ideas, and disruptions shaping the rise of smart cities and smart architecture.
