| Shape-memory alloys might help airplanes land without a peep Posted: 12 Jul 2021 03:33 PM PDT Having a home near a busy airport certainly has its perks. It is close to many establishments and alleviates the problem of wading through endless traffic to catch flights. But it does come at a cost -- tolerating the jarring sounds of commercial airplanes during landing and takeoff. Researchers have now conducted a computational study that validates using a shape-memory alloy to reduce the unpleasant plane noise produced during landing. |
| Posted: 12 Jul 2021 03:33 PM PDT Researchers have developed a new way to control and shape optical singularities.

| Posted: 12 Jul 2021 09:22 AM PDT The sharp eyes of an eagle, the extraordinary hearing of an owl - to successfully find food, the eyes and ears of birds have adapted optimally to their living conditions. Until now, the sense of smell has played a rather subordinate role. When meadows are freshly mowed, storks often appear there to search for snails and frogs. Researchers have now studied the birds' behavior and discovered that the storks are attracted by the smell of the mown grass. Only storks that were downwind and could thus perceive the smell reacted to the mowing. The scientists also sprayed a meadow with a spray of green leaf scents released during mowing. Storks appeared here as well. This shows that white storks use their sense of smell to forage and suggests that the sense of smell may also play a greater role in other birds than previously thought. |
| You can snuggle wolf pups all you want, they still won't 'get' you quite like your dog Posted: 12 Jul 2021 09:22 AM PDT You know your dog gets your gist when you point and say 'go find the ball' and he scampers right to it. This knack for understanding human gestures may seem unremarkable, but it's a complex cognitive ability that is rare in the animal kingdom. New research comparing dog puppies to human-reared wolf pups offers some clues to how dogs' unusual people-reading skills came to be. |

| Coastal ecosystems worldwide: Billion-dollar carbon reservoirs Posted: 12 Jul 2021 09:21 AM PDT Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt marshes and mangrove forests make an important contribution to mitigating climate change. |
| Haziness of exoplanet atmospheres depends on properties of aerosol particles Posted: 12 Jul 2021 09:21 AM PDT Many exoplanets have opaque atmospheres, obscured by clouds or hazes that make it hard for astronomers to characterize their chemical compositions. A new study shows that haze particles produced under different conditions have a wide range of properties that can determine how clear or hazy a planet's atmosphere is likely to be. |

| Technology that restores the sense of touch in nerves damaged as a result of injury Posted: 12 Jul 2021 09:21 AM PDT Researchers have developed a sensor that can be implanted anywhere in the body -- for example, under the tip of a severed finger. The sensor connects to another nerve that functions properly and restores tactile sensation to the injured nerve. The development is biocompatible and does not require electricity, wires, or batteries. |
| Ecologists develop a novel forensic tool for detecting laundering of critically endangered cockatoos Posted: 12 Jul 2021 09:21 AM PDT Ecologists have applied stable isotope techniques to determine whether birds in the pet trade are captive or wild-caught, a key piece of evidence required in many cases to determine whether a trade is legal or not. They have applied this technique to the yellow-crested cockatoo, a critically endangered species from Indonesia/Timor-Leste with a global population of fewer than 2,500. |
| Let crop residues rot in the field -- it's a climate win Posted: 12 Jul 2021 09:21 AM PDT Plant material that lies to rot in soil isn't just valuable as compost. In fact, agricultural crop residue plays a crucial role in sequestering carbon, which is vital for reducing global CO2 emissions. |
| Human environmental genome recovered in the absence of skeletal remains Posted: 12 Jul 2021 09:21 AM PDT Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which complicates analyses. A study has now successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years BP obtained from the cave of Satsurblia in the Caucasus (Georgia). |
| How the universe is reflected near black holes Posted: 12 Jul 2021 09:21 AM PDT In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression. |
| Mathematicians develop ground-breaking modeling toolkit to predict local COVID-19 impact Posted: 12 Jul 2021 09:21 AM PDT Mathematicians have created a new modeling toolkit which predicts the impact of COVID-19 at a local level with unprecedented accuracy. |
| Rise in Southeast Asia forest clearance increasing greenhouse gases Posted: 12 Jul 2021 09:21 AM PDT Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research.

| People given 'friendly' bacteria in nose drops protected against meningitis, study suggests Posted: 12 Jul 2021 09:21 AM PDT A recent trial has shown that nose drops of modified 'friendly' bacteria may protect against meningitis. |
| Sensing 'junk' RNA after chemotherapy enhances blood regeneration Posted: 12 Jul 2021 09:21 AM PDT Scientists reveal that during hematopoietic regeneration, RNA expressed from a part of the genome considered 'junk DNA' is used by hematopoietic stem cells to get activated and proliferate. The study shows that these so-called transposable elements make RNA after chemotherapy and activate an immune receptor which induces inflammatory signals enhancing hematopoietic stem cell cycling and thus participating in the regeneration of the hematopoietic system. |

Researchers have now identified a novel pathomechanism leading to Usher syndrome. They have discovered that the Usher syndrome type 1G protein SANS plays a crucial role in regulating splicing process. Furthermore, they have been able to demonstrate that defects in the SANS protein can lead to errors in the splicing of genes related to the Usher syndrome, which may provoke the disease. |
