Hurt/Caltech-JPL › Larger image › Larger image”/> For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation […]

Mars study yields clues to possible cradle of life

Mars study yields clues to possible cradle of life

From Science Daily The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. A recent international report examines observations by NASA’s Mars Reconnaissance Orbiter (MRO) of massive deposits in a basin on southern Mars. The authors interpret […]

3-D quantum gas atomic clock offers new dimensions in measurement

3-D quantum gas atomic clock offers new dimensions in measurement

From Science Daily JILA physicists have created an entirely new design for an atomic clock, in which strontium atoms are packed into a tiny three-dimensional (3-D) cube at 1,000 times the density of previous one-dimensional (1-D) clocks. In doing so, they are the first to harness the ultra-controlled behavior of a so-called “quantum gas” to […]

How tuberculosis hides in the body

How tuberculosis hides in the body

From Science Daily The tuberculosis vaccine only works for children. BCG (bacille Calmette-Guerin) doesn’t protect you as an adult. Now we know more about how the bacterium avoids being detected. Tuberculosis bacteria hide in the very cells that would normally kill them. Now we know more about how they evade recognition. Tuberculosis affects millions of […]

Dental surgery robot fits implants without human touch

From Technocracy News Medical robots driven by data and AI are coming for doctors, surgeons and dentists. One day, such procedures will be totally automated and overseen only by lower-skilled technicians. Displaced doctors will not be pleased with the Universal Basic Income that they are likely to receive. ⁃ TN Editor A robot dentist has carried out […]

Pigeons better at multitasking than humans

Pigeons better at multitasking than humans

From Science Daily Pigeons are capable of switching between two tasks as quickly as humans — and even more quickly in certain situations. These are the findings of biopsychologists who had performed the same behavioural experiments to test birds and humans. The authors hypothesize that the cause of the slight multitasking advantage in birds is […]

More evidence of water on Mars

More evidence of water on Mars

From Science Daily River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the most spectacular and densely packed river deposits seen on Mars. These deposits […]

Researchers have discovered how to program devices to dissolve electronics

Researchers have discovered how to program devices to dissolve electronics

From Freedom’s Phoenix (Natural News) A team of researchers from the University of Houston and China discovered a new type of electronic device that can be dissolved just by being exposed to water molecules in the atmosphere. The study was published in Science Advances. This model promised for environment-friendly disposable personal electronics and biomedical devices that dissolve within […]

Long sitting periods may be just as harmful as daily total

Long sitting periods may be just as harmful as daily total

From Science Daily A new study finds that it isn’t just the amount of time spent sitting, but also the way in which sitting time is accumulated during the day, that can affect risk of early death. The study, published online today in Annals of Internal Medicine, found that adults who sit for one to two […]
