Weird circles in the sky may be signs of a universe before ours

Posted by in categories: cosmology, existential risks, mathematics

By Chelsea Whyte

Swirling patterns in the sky may be signs of black holes that survived the destruction of a universe before the big bang.

“What we claim we’re seeing is the final remnant after a black hole has evaporated away in the previous aeon,” says Roger Penrose, a mathematical physicist at the University of Oxford.

SpaceX seeks approval for Starlink internet tests on high-performance govt. planes

Posted by in categories: internet, military, satellites

According to updated regulatory documents and recent Aviation Week interviews with the US Air Force Research Laboratory, it can be all but guaranteed that the USAF has begun working with SpaceX to test the feasibility of using the company’s planned Starlink satellite internet constellation for military communications purposes.

In early August, SpaceX updated regulatory documents required by the Federal Communications Commission (FCC) for the company to be permitted to experimental test its two prototype Starlink internet satellites, named Tintin A and B. Launched roughly six months ago as a copassenger on one of SpaceX’s own Falcon 9 rockets, the satellite duo has been quietly performing a broad range of tests on orbit, particularly focused on general satellite operations, orbital maneuvering with SpaceX’s own custom-built electric propulsion, and – most importantly – the experimental satellites’ cutting-edge communications capabilities.

Smart consumption management system for energy-efficient industrial companies

Posted by in categories: climatology, sustainability

Energy use in industrial buildings continues to skyrocket, contributing to the negative impact on global warming and Earth’s natural resources. An EU initiative introduced a disruptive system that’s able to reduce electricity consumption in the industrial sector.

Using energy efficiently helps industry save money, conserve resources and tackle climate change. ISO 50001 supports companies in all sectors to use energy more efficiently through the development of an system. It calls on the to integrate energy management into their overall efforts for improving quality and environmental management. Companies can perform several actions to successfully implement this new international standard, including creating policies for more efficient energy use, identifying significant areas of and targeting reductions.

Liquid battery could lead to flexible energy storage

Posted by in categories: energy, nanotechnology, sustainability, transportation

A new type of energy storage system could revolutionise energy storage and drop the charging time of electric cars from hours to seconds.

In a new paper published today in the journal Nature Chemistry, chemists from the University of Glasgow discuss how they developed a system using a nano-molecule that can store electric power or giving a new type of hybrid storage system that can be used as a flow battery or for hydrogen storage.

Their ‘hybrid-electric-hydrogen’ flow battery, based upon the design of a nanoscale battery molecule can store energy, releasing the power on demand as electric power or hydrogen gas that can be used a fuel. When a concentrated liquid containing the nano-molecules is made, the amount of energy it can store increases by almost 10 times. The energy can be released as either electricity or hydrogen gas meaning that the system could be used flexibly in situations that might need either a fuel or .

European aquaculture to benefit from a better quality of live feed

Posted by in categories: employment, food, sustainability

The aquaculture sector is growing, with fish farming being a key way to ensure Europe gets the quality food it needs without exploiting marine resources further. One key problem the industry faces is how to get the immature fish though their first few months – one EU project may be about to smooth the way.

Aquaculture is a growing market within the EU, bringing employment and providing a sustainable source of fish at a time when our marine life is under pressure. The main bottle-neck for the production of marine fish is the juvenile phase, especially during the time in which live diets are used. Even the established species, sea bream and sea bass, have a very low survival rate with an average of 25 percent. For new species in aquaculture, such as amberjack and tuna, the mortality is even higher.

The natural first feed for most is crustacean nauplii, the offspring of many types of crustacean zooplankton. Fish larvae is evolutionary adapted to such a diet, and it is believed that this type of prey fulfils the fish larva’s nutritional requirements.

State-of-the-art solar panel recycling plant

Posted by in categories: bioengineering, life extension, solar power, sustainability

The German engineering company Geltz Umwelt-Technologie has successfully developed an advanced recycling plant for obsolete or ageing solar panels.

As sales of solar power increase, there is a looming problem that is quite often overlooked: disposing waste from outdated or destroyed . A surge in solar panel disposal is expected to take place in the early 2030s, given the design life of installed around the millennium.

To address this problem before this big disposal wave, the EU has funded the ELSi project. With strong competencies in plant manufacturing and wastewater treatment including , the Geltz Umwelt-Technologie firm has built a test and treatment facility at a large disposal firm to retrieve reusable materials from solar modules.

The International Space Station (ISS) will be visible to the naked eye in several areas in the country starting tonight!

According to the NASA website, the space station looks like “an airplane or a very bright star moving across the sky” and moves considerably faster than a typical airplane.

U.S. $23 trillion will be lost if temperatures rise four degrees by 2100

Posted by in categories: climatology, economics, neuroscience, sustainability

Imagine something similar to the Great Depression of 1929 hitting the world, but this time it never ends.

Economic modelling suggests this is the reality facing us if we continue emitting greenhouse gases and allowing temperatures to rise unabated.

Economists have largely underestimated the global economic damages from climate change, partly as a result of averaging these effects across countries and regions, but also because the likely behaviour of producers and consumers in a climate change future isn’t usually taken into consideration in climate modelling.

Indonesia earthquake—how scrap tyres could stop buildings collapsing

Posted by in category: habitats

At the time of writing, 436 people have died following an earthquake in the Indonesian island of Lombok. A further 2,500 people have been hospitalised with serious injuries and over 270,000 people have been displaced.

Earthquakes are one of the deadliest natural disasters, accounting for just 7.5% of such events between 1994 and 2013 but causing 37% of deaths. And, as with all , it isn’t the countries that suffer the most earthquakes that see the biggest losses. Instead, the number of people who die in an earthquake is related to how developed the country is.
