A pair of researchers, one with the UK's Natural History Museum, the other a King Island historian, has found an almost complete extinct dwarf emu egg on King Island. In their paper published in the journal Biology Letters, ...
(PhysOrg.com) -- An unpiloted, air-breathing spaceplane that takes off from an airport runway, carries up to 30 passengers, and costs less than one-tenth to launch into space compared to a conventional rocket could be ready ...
(Phys.org) —Nanoscale writing offers a reliable way to record information at extremely high densities, making it a promising tool for patterning nanostructures for a variety of electronic applications. In a recent study, ...
(Phys.org) —Currently, precision laser ranging is limited to the Earth-Moon distance. These systems are based on passive laser ranging, so that the signal deteriorates as 1/R4 over distance R. In a new study, physicists ...
When it comes to explaining the evolution of human cooperation, researchers have traditionally looked to the iterated Prisoner’s Dilemma (IPD) game as the paradigm. However, the observed degree of cooperation among humans ...
(Phys.org)—For more than 100 years, scientists have debated the question: when light travels through a medium such as oil or water, does it pull or push on the medium? While most experiments have found that light exerts ...
(Phys.org) —Researchers with the Integrated Ocean Drilling Program (IODP) have presented findings at this year's Goldschmidt conference. They report having found bacteria, fungi and viruses living a mile and a half beneath ...
On Monday, October 19, 1987 – infamously known as “black Monday” – the Dow fell 508 points, or 22.9%, marking the largest crash in history. Using an analytical approach similar to the one applied to explore heart ...
(PhysOrg.com) -- Buried below the tundra of China’s Qinghai-Tibet Plateau is a type of frozen natural gas containing methane and ice crystals that could supply energy to China for 90 years. China discovered the large reserve ...
(PhysOrg.com) -- A new theory suggests the Moon was formed after a natural nuclear explosion in the Earth's mantle rather than after the impact of a massive object with the Earth, as previously thought.
