Image: The twisted shockwaves of an exploded star

Discovered on 5 September 1784 by astronomer William Herschel, the Veil Nebula was once a star. Now it is a twisted mass of shock waves that appears six times larger than the full Moon in the sky.

Rapid test kit detects dengue antibodies from saliva

Finding out whether you have been infected with dengue may soon be as easy as spitting into a rapid test kit. The Institute of Bioengineering and Nanotechnology (IBN) of A*STAR has developed a paper-based disposable device ...

Turtle embryos genetically wired for hotter summers

Endangered loggerhead turtles (Caretta caretta) are able to protect themselves against environmental temperature fluctuations while still in the egg, a UWA researcher has discovered.

Study uncovers secrets of a clump-dissolving protein

Workhorse molecules called heat-shock proteins contribute to refolding proteins that were once misfolded and clumped, causing such disorders as Parkinson's disease, amyotrophic lateral sclerosis, and Alzheimer's disease. ...

Sonic booms in nerves and lipid membranes

(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...

Rejigging the Cluster quartet

Aiming to study Earth's 'bow shock' in the solar wind, the constellation of Cluster satellites is being rejigged to bring two of the four to within almost touching distance.

Simulations aimed at safer transport of explosives

In 2005, a semi truck hauling 35,000 pounds of explosives through the Spanish Fork Canyon in Utah crashed and caught fire, causing a dramatic explosion that left a 30- by-70-foot crater in the highway.

Voyager 1 revealing regularity of interstellar shock waves

(Phys.org)—The "tsunami wave" that NASA's Voyager 1 spacecraft began experiencing earlier this year is still propagating outward, according to new results. It is the longest-lasting shock wave that researchers have seen ...

California gets funds for quake warning system

California has received a spurt of federal funding to expand an earthquake warning system intended to provide enough time for trains to brake, utilities and factories to shut off gas lines, and people to dive under a table ...
