A team of scientists at Karolinska Institutet has discovered a previously unknown meshlike organ in the skin that is sensitive to painful mechanical damage, such as pricks and impacts. Pain causes suffering and results in substantial costs for society. Almost one person in every five experiences constant pain and there is a considerable need to [...]
Drinking too much coffee or other caffeinated beverages may be a trigger for headaches among migraineurs, according to new research. Migraine is a disabling primary headache disorder affecting about one billion adults worldwide. Despite widespread anecdotal belief that caffeinated beverages may trigger migraine headaches and relieve headaches once they have begun, there is limited scientific [...]
An international team of researchers has discovered around 100 ancient volcanoes and associated lava flows buried deep within the Cooper-Eromanga Basins in central Australia. “The Cooper and Eromanga Basins of South Australia and Queensland are the largest onshore hydrocarbon producing region in Australia,” said Dr. Simon Holford from the University of Adelaide’s Australian School of [...]
NASA has released a stunning infrared image taken by the agency’s Spitzer Space Telescope of a lenticular galaxy called NGC 5866. NGC 5866 is located approximately 44 million light-years away in the constellation Draco. Also known as LEDA 53933 or UGC 9723, it has a diameter of 60,000 light-years - a little more than half [...]
A team of U.S. researchers has discovered a previously undescribed group of small molecule metabolites responsible for the green biofluorescence in two species of sharks. Not only is the newly-discovered chemical mechanism different from how most marine creatures glow, but it may also play other useful roles for the sharks, including helping them identify each [...]
Pulsars are rapidly rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds. If parts of the neutron star interior start to move outwards, the star spins faster. This is called a ‘glitch,’ and it’s providing astronomers with a brief insight into what lies within [...]
A new chip-based platform integrates nanopores and optofluidic technology with a feedback-control circuit to enable an unprecedented level of control over individual molecules and particles on a chip for high-throughput analysis.
Standard optical microscopes can image cells and bacteria but not their nanoscale features which are blurred by a physical effect called diffraction. Now, researchers report a simple way to bypass diffraction limitations using standard optical imaging tools.
An understanding of the molecular basis of differences in the incidence and survival of cancer between men and women may allow the discovery of specific and more effective treatments. The study compares the brain tumours of male and female flies at the molecular level and identifies proteins responsible for the different degree of aggressiveness.
A team of scientists is developing wearable skin sensors that can detect what's in your sweat. In a new article, the team describes a sensor design that can be rapidly manufactured using a ''roll-to-roll'' processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. The sensors can provide real-time measurements of sweat rate, and electrolytes and metabolites in sweat.
Scientists are shedding new light on the importance of light-sensing cells in the retina that process visual information. The researchers isolated the functions of melanopsin cells and demonstrated their crucial role in the perception of visual environment. This ushers in a new understanding of the biology of the eye and how visual information is processed.
Paleontologists have discovered a 360-million-year-old (Devonian period) fossilized forest of lycopsid trees near Xinhang in China’s Anhui province - the oldest known fossil forest in Asia. The Xinhang forest covered an area of at least 62 acres (250,000 m2) and grew in a coastal environment prone to flooding. Lycopsid trees found in the forest resembled [...]
Recently Weizmann Institute scientists succeeded in recording these rapid bursts of activity -- called 'hippocampal ripples' -- in the human brain, and they were able to demonstrate their importance as a neuronal mechanism underlying the engraving of new memories and their subsequent recall.
A team has discovered a biological system that manages cells' response to opioid drug exposure. The unexpected discovery offers new ideas for improving the safety of the one of the most effective, and most abused, group of pain medications.
Enteroviruses are one of the most common human pathogens leading to high number of acute and chronic infections worldwide. The physiological events leading to successful enterovirus infection are still poorly understood. Researchers have found significant new information concerning the role of Albumin and ions in host cell vesicles that promote genome release and efficient infection.
Scientists have solved a four decade long challenge of producing very thin nylon films that can be used for instance in electronic memory components. The thin nylon films are several 100 times thinner than human hair and could thus be attractive for applications in bendable electronic devices or for electronics in clothing.
