Phys.org / Physicists develop new method to measure universe's expansion rate
We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent ...
Phys.org / Urine tests confirm alcohol consumption in wild African chimpanzees
Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting ...
Phys.org / Finding the honey bee dance floor: New method shows how it moves within the hive
When honey bees find a good source of food, they return to their hive and perform a waggle dance. It consists of a series of movements that communicate the direction and distance to nectar, pollen or water relative to the ...
Phys.org / Water is bed bugs' kryptonite: The parasites avoid wet surfaces at all costs
Humans tend to fear bed bugs, and rightly so. The bloodsuckers are tough to get rid of once they've entered a home. But new research has, for the first time, identified one thing the bugs seem to fear—water and wet surfaces.
Phys.org / Major gap in Earth's rock record likely due to tectonics—not glaciers
The Great Unconformity is a major gap in Earth's geologic record. The missing layer between Precambrian and Cambrian rocks represents a gap of around a billion years of history. Among much debate surrounding the cause of ...
Phys.org / Mysterious Greek inscription reignites debate on whether a Syrian mosque stands atop Roman Emperor Elagabalus' Temple
A recently discovered Greek inscription at the base of a column inside the Great Mosque of Homs in Syria has rekindled a longstanding scholarly debate about the exact location of the Temple of the sun, whose high priest ascended ...
Phys.org / Thunderstorms conjure ghostly coronae in treetops, observed outdoors for the first time
For the first time, researchers have observed and measured weak electrical discharges, known as coronae, on trees during thunderstorms. A new study describes the near-invisible sparkles appearing similarly on branches of ...
Phys.org / Language barriers slow down the international diffusion of knowledge, study finds
Rapid technological and scientific advances have fueled a huge wave of innovation over the past decades. The speed of global innovation is known to be dependent on the exchange of knowledge and skills between different nations ...
Medical Xpress / A 3D-printed swallowable robot could perform gastrointestinal procedures
Recent technological advances have opened new possibilities for the development of advanced medical devices, including tiny robots that can safely move inside the human body. Some of these systems could help to simplify complex ...
Tech Xplore / A new eco-friendly water battery could theoretically last for centuries
The problem with many types of modern batteries is that they rely on harsh chemicals to work. Not only can these corrosive liquids damage internal parts over time, but they can also leach into soil and water when disposed ...
Phys.org / New generation of climate models sheds first light on long-standing Pacific puzzle
Researchers have long been puzzled by the observed cooling of the eastern tropical Pacific and the Southern Ocean accompanying global warming. Existing climate models have failed to capture this pattern. At the Max Planck ...
Phys.org / Supercomputer simulations reveal rotation drives chemical mixing in red giant stars
Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they evolve?
