Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene
Wed, 16 Aug 2017 16:26:00 EDT
As graphene's popularity grows as an advanced 'wonder' material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the research group has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide in the form of carbonic acid as the electrolyte solution.
Changing tides: Lake Michigan could best support lake trout and steelhead
Wed, 16 Aug 2017 16:06:31 EDT
Invasive mussels and less nutrients from tributaries have altered the Lake Michigan ecosystem, making it more conducive to the stocking of lake trout and steelhead than Chinook salmon, according to a recent US Geological Survey and Michigan State University study.
Scientists discover powerful potential pain reliever
Wed, 16 Aug 2017 16:06:22 EDT
Chemists have discovered a powerful pain reliever that acts on a previously unknown pain pathway. The compound is as effective at relieving neuropathic pain in injured mice as a drug widely used for pain relief called gabapentin. If they can demonstrate that it is safe, effective and nonaddictive in humans -- a process that typically takes years -- the discovery could address one of today's biggest public health challenges: the opioid abuse epidemic.
Comparing the jaws of porcupine fish reveals three new species
Wed, 16 Aug 2017 16:06:15 EDT
Researchers compared fossil porcupine fish jaws and tooth plates collected on expeditions to Panama, Colombia, Venezuela and Brazil with those from museum specimens and modern porcupine fish, revealing three new species.
Problems with DNA replication can cause epigenetic changes that may be inherited for several generations
Wed, 16 Aug 2017 14:53:57 EDT
Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations. They also identified the cause of these epigenetic changes, which is related to the loss of a molecular mechanism in charge of silencing genes. Their results will change the way we think about the impact of replication stress in cancer and during embryonic development, as well as its inter-generational inheritance.
Larvaceans provide a pathway for transporting microplastics into deep-sea food webs
Wed, 16 Aug 2017 14:51:49 EDT
A new article shows that filter-feeding animals called giant larvaceans can collect and consume microplastic particles, potentially carrying microplastics to the deep seafloor.
Lithium-air batteries: Mystery about proposed battery material clarified
Wed, 16 Aug 2017 14:18:35 EDT
A compound called lithium iodide (LiI) has been considered a leading material for lithium-air batteries, which could deliver more energy per pound compared to today's leading batteries. A new study helps explain previous, conflicting findings about the material's usefulness for this task.
Spray-on electric rainbows: Making safer electrochromic inks
Wed, 16 Aug 2017 14:18:32 EDT
A flick of a switch, and electrochromic films change their colors. Now they can be applied more safely and more commonly thanks to an innovative chemical process that makes them water soluble. They can be sprayed and printed, instead of being confined behind safety implements to handle volatile solvents and their toxic fumes.
Boron nitride foam soaks up carbon dioxide
Wed, 16 Aug 2017 14:18:30 EDT
Researchers have created a reusable hexagonal-boron nitride foam that soaks up more than three times its weight in carbon dioxide.
Superconductivity research reveals potential new state of matter
Wed, 16 Aug 2017 13:47:36 EDT
A potential new state of matter is being reported with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common. The ability to find similarities and differences among classes of materials with phenomena such as this helps researchers establish the essential ingredients that cause novel functionalities such as superconductivity.
Smart fabric neutralizes nerve gas
Wed, 16 Aug 2017 13:47:33 EDT
A groundbreaking development has the potential to thwart chemical warfare agents: smart textiles with the ability to rapidly detect and neutralize nerve gas.
Mystery of how first animals appeared on Earth solved
Wed, 16 Aug 2017 13:47:27 EDT
Research has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.
Popular immunotherapy target turns out to have a surprising buddy
Wed, 16 Aug 2017 13:47:24 EDT
The majority of current cancer immunotherapies focus on PD-L1. This well-studied protein turns out to be controlled by a partner, CMTM6, a previously unexplored molecule that is now suddenly also a potential therapeutic target.
Scientists use magnetic fields to remotely stimulate brain -- and control body movements
Wed, 16 Aug 2017 13:46:58 EDT
Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremities -- an achievement that could lead to advances in studying and treating neurological disease.
Scientists give star treatment to lesser-known cells crucial for brain development
Wed, 16 Aug 2017 13:46:50 EDT
After decades of relative neglect, star-shaped brain cells called astrocytes are finally getting their due. To gather insight into a critical aspect of brain development, a team of scientists examined the maturation of astrocytes in 3-D structures grown in culture dishes to resemble human brain tissue. The study confirms the lab-grown cells develop at the same rate as those found in human brains.
Using barcodes to trace cell development
Wed, 16 Aug 2017 13:46:45 EDT
There are various concepts about how blood cells develop. However, they are based almost exclusively on experiments that solely reflect snapshots. Scientists now present a novel technique that captures the process in a dynamic way. Using a 'random generator,' the researchers label hematopoietic stem cells with genetic barcodes that enable them to trace which cell types arise from the stem cell.
Supermassive black holes feed on cosmic jellyfish
Wed, 16 Aug 2017 13:46:43 EDT
Observations of 'Jellyfish galaxies' with ESO's Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly.
Modern genetic sequencing tools give clearer picture of how corals are related
Wed, 16 Aug 2017 13:46:38 EDT
As corals face threats from ocean warming, a new study uses the latest genetic-sequencing tools to help unravel the relationships between three similar-looking corals.
Making surgery safer by helping doctors see nerves
Wed, 16 Aug 2017 12:24:01 EDT
A new noninvasive approach that uses polarized light to make nerves stand out from other tissue could help surgeons avoid accidentally injuring nerves or assist them in identifying nerves in need of repair.
The nerve-guiding 'labels' that may one day help re-establish broken nervous connections
Wed, 16 Aug 2017 12:23:58 EDT
Working with fruit flies, scientists have identified different labels that attract and control specific nerves. In theory, the 'right' labels may re-form nervous connections if delivered to the site of injury.
