Shape-memory alloys might help airplanes land without a peep

Science Daily - 13/07/2021
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.

Optical singularities could be used for wide range of applications from super resolution imaging to optical trapping

Science Daily - 13/07/2021
Researchers have developed a new way to control and shape optical singularities. The technique can be used to engineer singularities of many shapes, far beyond simple curved or straight lines. It could be used for a wide range of applications from super resolution imaging to optical trapping.

Neutron-clustering effect in nuclear reactors demonstrated

The long-theorized neutron-clustering effect in nuclear reactors has been demonstrated, which could improve reactor safety and create more accurate simulations, according to a new study.

When a single tree makes a difference

Science Daily - 13/07/2021
A single tree along a city street or in a backyard can provide measurable cooling benefits, according to a new study.

Discovery of 10 faces of plasma leads to new insights in fusion and plasma science

Science Daily - 13/07/2021
Scientists uncover new properties of plasma that have wide potential applications for astrophysical and fusion plasmas.

Trace gas phosphine points to volcanic activity on Venus, scientists say

Science Daily - 13/07/2021
Last autumn, researchers reported finding the gas phosphine in trace amounts in Venus' upper atmosphere, raising the slim possibility of a biological signature. Now scientists say that the phosphine's chemical fingerprints support a different find: evidence of explosive volcanoes.

Childhood lead exposure may adversely affect adults' personalities

Science Daily - 13/07/2021
A study sampled more than 1.5 million people in 269 U.S. counties and 37 European nations. Researchers found that those who grew up in areas with higher levels of atmospheric lead had less adaptive personalities in adulthood -- lower levels of conscientiousness and agreeableness and higher levels of neuroticism.

Mapping how sea-level rise adaptation strategies impact economies and floodwaters

Science Daily - 13/07/2021
By 2100, sea levels are expected to rise by almost seven feet in the Bay Area. New research shows how traditional approaches to combating sea-level rise can create a domino effect of environmental and economic impacts for nearby communities.

Magnetic field from MRI affects focused-ultrasound-mediated blood-brain barrier

Science Daily - 13/07/2021
Researchers have found that the magnetic field of the MRI scanner decreased the BBB opening volume by 3.3-fold to 11.7-fold, depending on the strength of the magnetic field, in a mouse model.

New technique reduces nicotine levels, harmful compounds simultaneously in tobacco

Science Daily - 12/07/2021
Researchers have developed a new technique that can alter plant metabolism. Tested in tobacco plants, the technique showed that it could reduce harmful chemical compounds, including some that are carcinogenic. The findings could be used to improve the health benefits of crops.

Mapping extreme snowmelt and its potential dangers

In a mouse model, brain regions involved in working memory present a modular network organization that is critical for persistent neural activity.

The Equalizer: An engineered circuit for uniform gene expression

Science Daily - 12/07/2021
Researchers deloped a new genetic circuit called the Equalizer that leads to uniform gene expression.

Artificial intelligence could be new blueprint for precision drug discovery

Science Daily - 12/07/2021
Researchers have described a new approach that uses machine learning to hunt for disease targets and then predicts whether a drug is likely to receive FDA approval.

MaxDIA: Taking proteomics to the next level

Science Daily - 12/07/2021
A new software improves data-independent acquisition proteomics by providing a computational workflow that permits highly sensitive and accurate data analysis.

Electric delivery vehicles: When, where, how they’re charged has big impact on greenhouse gas emissions

Science Daily - 12/07/2021
The transportation sector is the largest contributor to greenhouse gas emissions in the United States, and a lot of attention has been devoted to electric passenger vehicles and their potential to help reduce those emissions.

Novel screening approach improves diagnosis of metabolic disorders in newborns

Science Daily - 12/07/2021
A screening method known as untargeted metabolomics profiling can improve the diagnostic rate for inborn errors of metabolism, a group of rare genetic conditions, by about seven-fold when compared to the traditional metabolic screening approach.

The fine nose of storks

Science Daily - 12/07/2021
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

Science Daily - 12/07/2021
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.

Teardrop star reveals hidden supernova doom
