Batteries that “drink” seawater could power long-range underwater vehicles
19th June 2017 phys.org | Tech

The long range of airborne drones helps them perform critical tasks in the skies. Now MIT spinout Open Water Power (OWP) aims to greatly improve the range of unpiloted underwater vehicles (UUVs), helping them better perform in a range of applications under the sea.

Researchers create a high-temperature device that produces electricity from industrial waste heat
19th June 2017 phys.org | Tech

Glass and steel makers produce large amounts of wasted heat energy at high temperatures, but solid-state thermoelectric devices that convert heat to electricity either don’t operate at high enough temperatures or cost so much that their use is limited to special applications such as spacecraft. MIT researchers have developed a liquid thermoelectric device with a molten compound of tin and sulfur that can efficiently convert waste heat to electricity, opening the way to affordably transforming waste heat to power at high temperatures.

Neural networks take on quantum entanglement

Ambulances are so 2016. After a cardiac arrest, the fastest way to send help is on a flying drone
16th June 2017 | latimes.com | Tech

The best medicine for a person going into sudden cardiac arrest is an electric shock. That jolt temporarily stops the heart, along with its rapid or erratic beat. When the heart starts itself up again, it can revert to its normal rhythm and resume pumping blood to the brain and the rest of the body.

Mosquito-killing fungi engineered with spider and scorpion toxins could help fight malaria
16th June 2017 | sciencedaily.com | Animal Life, Tech

A mosquito-killing fungus genetically engineered to produce spider and scorpion toxins could serve as a highly effective biological control mechanism to fight malaria-carrying mosquitoes, scientists report. The fungus is specific to mosquitoes and does not pose a risk to humans. Further, the study results suggest that the fungus is also safe for honey bees and other insects.

Concept could sustainably meet human resource needs of ‘full Earth’
15th June 2017 phys.org | Earth, Tech

A new concept proposes to provide food, energy and water resources for the world’s growing population by combining systems that simultaneously use different parts of sunlight’s spectrum to produce crops, generate electricity, collect heat and purify water.

Particle Accelerators Are Changing the Way We Look at Ancient Turds
13th June 2017 gizmodo.com | Ancient, Tech

Most of the methods used to look at fossilized shit, more commonly called coprolites, are fairly outdated. Scientists mainly use two-dimensional imaging techniques that require cutting literal slices of the sample to look at them up close. Three-dimensional imaging methods in the lab might miss the smallest features like hairs or insect legs. But a team of Swedish scientists have a better way to reveal the poo’s secrets: particle accelerators.

Self-Replicating 3D Printers Could Build Moon Bases, Fight Global Warming
13th June 2017 | space.com | Space, Tech

A 3D printer that could re-create itself from lunar material is in development at a university in Canada.

The technology could one day enable humans to 3D-print lunar bases, as well as conduct in-space manufacturing of satellites and solar shields on the moon that could help fight global warming
