Zealandia: Is there an eighth continent under New Zealand? - BBC News

Zealandia: Is there an eighth continent under New Zealand? - BBC News | Physical Science - SHS | Scoop.it
It's almost all under water, but Zealandia should be considered a continent, say researchers.
Joy Kinley's insight:
Most of the continent is underwater but if there is a cold part of an Ice Age, New Zealand can get massively bigger.

Water Shortages May Cut Short US Energy Revolution. What’s Needed? · Environmental Leader · Environmental Management News

Water Shortages May Cut Short US Energy Revolution. What’s Needed? · Environmental Leader · Environmental Management News | Physical Science - SHS | Scoop.it

With the shale gas boom reverberating across the United States, the country has found an abundant and cheap energy source — one that is reducing energy costs for corporations while also cutting the emissions of industrials and utilities.

Joy Kinley's insight:

Water is necessary for fracking.  Because of the size of the United States some regions are experiencing drought that will limit this drilling.

Deep-space travel may be fueled by a healthy diet of prunes | Science! | Geek.com | Physical Science - SHS | Scoop.it

Science has given a clue as to how humans might survive out in the depths of space. The answer: Dried prunes.

Joy Kinley's insight:

Ok, who would have thought that prunes would be so helpful.  They would pack easy since they are dried fruits.  There is only one problem prunes are very high in fiber so don't eat to many of them.

Gravitational wave detection could be a false alarm

Gravitational wave detection could be a false alarm | Physical Science - SHS | Scoop.it

Caution is needed over claims that gravitational waves have been found. It could be a fake to test the detectors and scientists involved – it has been before

Joy Kinley's insight:

Einstein thought that gravitational waves existed but that it would be difficult to locate them.  It looks like they have been discovered but the results need to be duplicated and studied further.

Fishers and conservationists urge release of herpes virus to kill Murray river carp

Fishers and conservationists urge release of herpes virus to kill Murray river carp | Physical Science - SHS | Scoop.it

Unlikely alliance says specialised disease will transform rivers and protect native fish species after exponential growth in numbers of the European invader

Joy Kinley's insight:

The carp were an invasive species in Australia and have caused a great deal of damage to the ecosystem.  Let's hope that the fish herpes can't mutate enough to spread to the native species.

Intelligent bandage glows when it detects an infection | Science! | Geek.com | Physical Science - SHS | Scoop.it

Scientist have developed a band-aid that turns florescent green, warning doctors when it senses the onset of an infection. Pretty smart. The developers are a group of researchers at the University of Bath.

Joy Kinley's insight:

This would help keep antibiotic use down and help people get to a doctor when infection is setting in so they can get treatment at the start of a problem.

Astronaut Scott Kelly and his twin brother used to be the same height. But that may not be true when they stand side by side for the first time in nearly a year.

The lessened gravity of space allows for the vertebra in the back to move and most astronauts grow some after they spend time in space.  Alas, the effects go away after time back on Earth.

A lightbulb moment for the old-fashioned filament

A lightbulb moment for the old-fashioned filament | Physical Science - SHS | Scoop.it

Do you yearn for the soft, instant light of the incandescent bulb? Edison’s invention could be back – in an even more efficient form than energy-saving fluorescents

Joy Kinley's insight:

Most of the energy being used in a traditional light-bulb is lost to heat, which anyone that has tried to change a just burnt out light knows.  The push has been to use the efficient which take longer to get bright and produce a different color light.
