| Novel small molecule potently attenuates neuroinflammation in brain and glial cells Posted: 23 Sep 2021 04:11 PM PDT In a preclinical study show that their small molecule drug, SRI-42127, can potently attenuate the triggers of neuroinflammation. These experiments in glial cell cultures and mice now open the door to testing SRI-42127 in models of acute and chronic neurological injury. |
| If endangered primates disappear, so will their parasites. That's actually a problem Posted: 23 Sep 2021 04:11 PM PDT People are more aware of the plight of endangered gorillas than of gorillas' gut worms, and are understandably more enamored with mouse lemurs than their mites. Half of the world's roughly 500 primate species are at risk of extinction due to human activities such as hunting, trapping and deforestation. But the demise of the world's threatened primates could also trigger even more extinctions for the parasites that lurk within them, finds a new study. |
| A new solid-state battery surprises the researchers who created it Posted: 23 Sep 2021 01:59 PM PDT Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense. It holds promise for a wide range of applications from grid storage to electric vehicles. |

| Decoding birds’ brain signals into syllables of song Posted: 23 Sep 2021 12:33 PM PDT Researchers can predict what syllables a bird will sing -- and when it will sing them -- by reading electrical signals in its brain, reports a new study. The work is an early step toward building vocal prostheses for humans who have lost the ability to speak. |
| More support needed for pollination services in agriculture Posted: 23 Sep 2021 10:26 AM PDT The global decline of pollinators threatens the reproductive success of 90 per cent of all wild plants globally and the yield of 85 per cent of the world's most important crops. Pollinators -- mainly bees and other insects -- contribute to 35 per cent of the world's food production. The service provided by pollinators is particularly important for securing food produced by the more than two billion small farmers worldwide. An agroecologist points out that yields could be increased if pollinators were encouraged. |

| Physicists control the flow of electron pulses through a nanostructure channel Posted: 23 Sep 2021 08:56 AM PDT Particle accelerators are essential tools in research areas such as biology, materials science and particle physics. Researchers are always looking for more powerful ways of accelerating particles to improve existing equipment and increase capacities for experiments. One such powerful technology is dielectric laser acceleration (DLA). In this approach, particles are accelerated in the optical near-field which is created when ultra-short laser pulses are focused on a nanophotonic structure. Using this method, researchers have succeeded in guiding electrons through a vacuum channel, an essential component of particle accelerators. |
| How tactile vibrations create illusions Posted: 23 Sep 2021 08:56 AM PDT Among the traditional five human senses, touch is perhaps the least studied. Yet, it is solicited everywhere, all the time, and even more so in recent years with the widespread daily use of electronic devices that emit vibrations. Indeed, any moving object transmits oscillatory signals that propagate through solid substrates. Our body detects them by means of mechanoreceptors located below the skin and transmits the information to the brain similarly to auditory, olfactory or visual stimuli. By studying how mice and humans perceive tactile vibrations, researchers discovered that the brain does not reliably perceive the frequency of a vibration when its amplitude varies. An illusory phenomenon is thereby created, which highlights how far our perception of the world around us can deviate from its physical reality. |

| Researchers translate insect defense chemicals into eerie sounds Posted: 23 Sep 2021 08:56 AM PDT Sawfly larvae protect themselves by secreting cocktails of unpleasant, volatile chemicals intended to repel predators, particularly ants. Researchers can assess the effectiveness of these defenses by staging meetups, so-called bioassays, between prey and predator. But entomologist have taken a different approach, translating the secretions' chemical composition into sounds, and measuring how humans react. |

| Posted: 23 Sep 2021 07:20 AM PDT We can learn a lot by studying microscopic and macroscopic changes in a material as it crosses from one phase to another, for example from ice to water to steam. A new study examines systems transitioning from 'normal' fluid to a quantum state known as a superfluid, which can flow with zero friction, with a view to future, superfluid-based, quantum technologies, such as ultra-low energy electronics. |
| Are too many Phase III cancer clinical trials set up to fail? Posted: 23 Sep 2021 07:20 AM PDT New research finds four out of five cancer therapies tested in Phase III trials do not achieve clinically-meaningful benefit in prolonging survival, and is the first study to quantify the number of false-positive, false-negative, and true-negative trial results. |

| Continental growth is not a continuous process Posted: 22 Sep 2021 11:32 AM PDT The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, researchers have uncovered a new geological history of the continents. The research shows that their growth was not a continuous process, and that they have always been rich in silica1. This new study calls into question certain models of the onset of plate tectonics and provides us with a better understanding of continental growth through time. |
| Immune cells in the brain share the work Posted: 22 Sep 2021 10:30 AM PDT To break down toxic proteins more quickly, immune cells in the brain can join together to form networks when needed. However, in certain mutations that can cause Parkinson's disease, this cooperation is impaired. |
