Soft gold enables connections between nerves and electronics
Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis
A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.
Astronomers uncover risks to planets that could host life
A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
Hydraulic lift technology may have helped build Egypt's iconic Pyramid of Djoser
The Pyramid of Djoser, the oldest of Egypt's iconic pyramids, may have been built with the help of a unique hydraulic lift system, according to researchers. A new study suggests that water may have been able to flow into two shafts located inside the pyramid itself, where that water could have been used to help raise and lower a float used to carry the building stones.
Physicists develop new method to combine conventional internet with the quantum internet
Researchers send entangled photons and laser pulses of the same color over a single optical fiber for the first time.
Scientists pin down the origins of the moon's tenuous atmosphere
When it comes to DNA replication, humans and baker's yeast are more alike than different
Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the first time a molecular complex -- called CTF18-RFC in humans and Ctf18-RFC in yeast -- that loads a 'clamp' onto DNA to keep parts of the replication machinery from falling off the DNA strand.
Half a billion-year-old spiny slug reveals the origins of mollusks
Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.
Modern behavior explains prehistoric economies
What if the 'Market Economy' always existed? Archaeologists tried to answer this question by researching how much Bronze Age people used to spend to sustain their daily lives. Their results show that, starting at least 3,500 years ago, the spending habits of prehistoric Europeans were not substantially different from what they are today.
Smell reports reveal the need to expand urban air quality monitoring, say researchers
Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.
Scientists devise method to secure Earth's biodiversity on the moon
New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
The rotation of a nearby star stuns astronomers
Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.
Bright prospects for engineering quantum light
Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?
