Discarded napkin helps US police crack 32-year-old murder mystery

2 hours 55 min ago

The mystery of the sexual assault and murder of a US teenager in Washington state has been resolved 32 years after the crime thanks to a discarded napkin, DNA tests and genetic genealogy. Gary Hartman, 66, has been arrested and is scheduled to appear in court Monday on rape and murder charges in the case, which has long shocked the city of Tacoma, in the northwestern US state. It began on March 26, 1986, when 12-year-old Michella Welch disappeared while playing with her two young sisters at a park.

This insane golden chamber contains water so pure it can dissolve metal, and is helping scientists detect dying stars

13 hours 49 min ago

The Super-Kamiokande neutrino detector is a physics experiment the size of a 15-storey building, buried under a mountain in Japan. Neutrinos are sub-atomic particles that pass through us all the time, and studying them can tell us about supernovas and the composition of the universe. The detector is full of ultra-pure water, which can leach the nutrients out of your hair and dissolve metal.

Identifying U.S. troops returned from North Korea may be challenging: experts

Fri, 06/22/2018 - 18:05

By Daphne Psaledakis WASHINGTON (Reuters) - The U.S. military will face a difficult task in identifying the remains of soldiers missing from the Korean War as the Pentagon prepares to receive them from North Korea in coming days, officials and experts said. U.S. President Donald Trump, who met with North Korean leader Kim Jong Un at an historic summit in Singapore this month, said on Thursday that Pyongyang was in the process of returning the remains of U.S. troops missing from the 1950-1953 conflict. The Pentagon has said North Korean officials have indicated in the past they have the remains of as many as 200 U.S. troops, and Trump himself has mentioned that figure.

New, long-extinct ape species found in ancient Chinese tomb

Fri, 06/22/2018 - 10:43

An entirely new but long-extinct ape species has been discovered in an ancient tomb in central China. The skull and jaw of the never-before-seen gibbon were found in Shaanxi province inside a royal burial chamber that was built some 2,300 years ago. The previously unknown genus and species of gibbon, which researchers have named Junzi imperialis, may be the first ape to have become extinct due to humans, according to a new study published in the journal Science on Friday.

The International Space Station is about to create the coldest spot in the entire universe

Fri, 06/22/2018 - 08:56

Space is a chilly place, but scientists aboard the International Space Station are about to make it just a little bit colder — temporarily, at least. The crew is about to power up a small device called the Cold Atom Laboratory to plunge atoms into temperatures close to absolute zero.

As NBC Mach reports, the experiments will focus on the movements of particles at temperatures that are just barely above absolute zero — the theoretical temperature in which all movement stops — in order to observe some of the quirks of quantum mechanics. If you've ever even casually looked into research based on quantum mechanics you already know that things are about to get weird.

For an example of just how bizarre things can get in the world of quantum physics you only need to look at the launch of a Chinese satellite from early in 2017. The satellite used a strange quirk known as quantum entanglement to send an "unhackable" message nearly 750 miles to Earth.

Quantum entanglement allows two particles called "twins" to behave in unison even though they are separated by incredibly long distances. Any kind of interaction with one of the particles will result in the other particle reacting in the same manner, almost as though both the particles are actually one, existing in two places at the same time. It's some seriously mind-boggling stuff, but it's totally real, and scientists are eager to learn more about it.

By cooling particles to incredibly low temperatures, scientists have a better opportunity to observe the behavior of these kinds of particles. The low-gravity environment of the space station makes it an ideal place for this kind of testing, and will give researchers more time to observe the chilled particle clouds before they break down.

The work will actually be conducted by scientists here on Earth, and the tiny laboratory won't require any assistance from the crew of the space station. The remote experiments can be performed for nearly seven hours per day, which will give researches plenty of time to try to untangle the mysteries of the universe.

Cambridge University discovers how to stop irritating ‘plink plink’ of dripping tap

Fri, 06/22/2018 - 08:00

The irritating "plink, plink" sounds of a dripping tap has caused many a sleepless night. But now Cambridge University has discovered what causes it, and how to stop it. Using ultra-high-speed cameras and audio capture techniques, researchers found the noise is produced by the movement of a small bubble of air trapped beneath the water’s surface. The bubble forces the water surface itself to vibrate, creating the sound as it hits an empty, or water-filled sink below. However changing the surface tension of the water that the drops are falling onto by adding washing up liquid causes the sound to vanish. “A lot of work has been done on the physical mechanics of a dripping tap, but not very much has been done on the sound,” said Dr Anurag Agarwal of Cambridge’s Department of Engineering, who led the research. “But thanks to modern video and audio technology, we can finally find out exactly where the sound is coming from, which may help us to stop it.” Ultra slow speed cameras and specialist audio recorders were able to pick out the exact moment the sound is produce as a drop hits the surface  Credit: University of Cambridge  Dr Agarwal decided to investigate the problem after while visiting a friend’s house who had a leak in his roof. “While I was being kept awake by the sound of water falling into a bucket placed underneath the leak, I started thinking about this problem,” he said. “The next day I discussed it with my friend and another visiting academic, and we were all surprised that no one had actually answered the question of what causes the sound.” The earliest photographs of drop impacts were published in 1908, and the fluid mechanics of a water droplet hitting a liquid surface are well-known, but nobody had got to the bottom of the mystery "plink". In their experiment, the Cambridge researchers found that, the initial splash, the formation of the cavity, and the jet of liquid are all effectively silent. The source of the sound is only down to the trapped air bubble. “Using high-speed cameras and high-sensitivity microphones, we were able to directly observe the oscillation of the air bubble for the first time, showing that the air bubble is the key driver for both the underwater sound, and the distinctive airborne ‘plink’ sound,” said doctoral student Sam Phillips. “However, the airborne sound is not simply the underwater sound field spreading to the surface, as had been previously thought.” According to the researchers, the results could also used to develop more efficient ways to measure rainfall. The research was published in the journal Scientific Reports.
