Muscle biopsy test for biomarker could lead to earlier diagnosis of ALS

Posted: 21 Jun 2022 03:45 PM PDT

Amyotrophic lateral sclerosis (ALS) is a progressive disease of the nervous system. It affects nerve cells in the brain and spinal cord called motor neurons. Motor neurons control muscle movement and ALS causes them to deteriorate and eventually die. The motor neurons lose the ability to send messages to the muscles in the body, affecting voluntary muscle movements. There have been recent advances in treating ALS, but current treatments can only slow disease progression. That is why it is important to diagnose ALS as early as possible.

2021 heat wave created 'perfect storm' for shellfish die-off

Posted: 21 Jun 2022 03:45 PM PDT

It's hard to forget the excruciating heat that blanketed the Pacific Northwest in late June 2021. Temperatures in Oregon, Washington and British Columbia soared to well above 100 degrees Fahrenheit, with Seattle setting an all-time heat record of 108 degrees on June 28. A team has now compiled and analyzed hundreds of field observations to produce a comprehensive report of the impacts of the 2021 heat wave on shellfish.

Quantum sensor can detect electromagnetic signals of any frequency

Posted: 21 Jun 2022 03:44 PM PDT

Researchers developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness.

Researchers derive new theory on behavior of new class of materials

Posted: 21 Jun 2022 03:44 PM PDT

Researchers have derived the governing equations that describe and explain the macroscopic mechanical behavior of elastomers filled with liquid inclusions directly in terms of their microscopic behavior.

Plant virus plus immune cell-activating antibody clear colon cancer in mice, prevent recurrence

Posted: 21 Jun 2022 03:44 PM PDT

A new combination therapy to combat cancer could one day consist of a plant virus and an antibody that activates the immune system's 'natural killer' cells, shows a new study. In mouse models of colon cancer, the combination therapy eliminated all tumors and prevented their recurrence, which in turn resulted in 100% survival. The therapy also increased survival in mouse models of melanoma.

What the nose doesn't know helps wildlife: Using olfactory cues to protect vulnerable species

Posted: 21 Jun 2022 01:33 PM PDT

Behavioral ecologists have discovered a way to harness animals' olfactory ability to protect vulnerable plants and endangered animals.

Researchers harness the power of a new solid-state thermal technology

Posted: 21 Jun 2022 12:51 PM PDT

Researchers have discovered a way to make a versatile thermal conductor, with promise for more energy-efficient electronic devices, green buildings and space exploration. They have demonstrated that a known material used in electronic equipment can now be used as a thermal regulator, too, when it is in a very pure form. This new class of material gives engineers the ability to make thermal conductivity increase or decrease on demand, changing a thermal insulator into a conductor and vice versa.

Pacific whiting skin has anti-aging properties that prevent wrinkles, research suggests

Posted: 21 Jun 2022 11:18 AM PDT

The gelatin in the skin of Pacific whiting, an abundant fish on the Pacific Coast of North America, may help prevent skin wrinkling caused by ultraviolet radiation, a new study found.

COVID-19 rebound after taking Paxlovid likely due to insufficient drug exposure, study finds

COVID-19 rebound following Paxlovid treatment likely due to insufficient drug exposure, researchers find after showing rebound patient did not show drug resistance or impaired immunity.

Robots turn racist and sexist with flawed AI, study finds

Posted: 21 Jun 2022 11:17 AM PDT

A robot operating with a popular Internet-based artificial intelligence system consistently gravitates to men over women, white people over people of color, and jumps to conclusions about peoples' jobs after a glance at their face. The work is believed to be the first to show that robots loaded with an accepted and widely-used model operate with significant gender and racial biases.

High vaccination rates blunted Delta variant surge in some US states

Posted: 21 Jun 2022 08:47 AM PDT

A joint modelling initiative by nine teams predicted the U.S. surge of COVID-19 caused by the Delta variant of the SARS-CoV-2 virus in the summer of 2021, and found vaccination uptake to be critical to limiting transmission.

Research highlights importance of large wood in streams for land-based animals

Posted: 21 Jun 2022 07:56 AM PDT

Land managers have invested millions of dollars annually since the 1980s to place large pieces of wood back in streams, owing primarily to its importance for fish habitat. But little is known about how large wood in streams impacts birds and land-based animals. Scientists are beginning to change that with a just-published paper that outlines what they observed from one year of footage from motion-triggered video cameras they set up near multiple large log jams in a creek just west of Corvallis, Oregon.

Natural mineral hackmanite can change color almost indefinitely enabling numerous applications

Posted: 21 Jun 2022 07:56 AM PDT

While investigating hackmanite, a natural wonder material, researchers found that it, in addition to two other minerals, can change their color upon exposure to UV radiation repeatedly without wearing out. The results show that the inexpensive hackmanite, which is easy to synthesise, is also an excellent material because of its high durability and applicability for different purposes.

Females far likelier to suffer with Long COVID, a new review of studies shows, underscoring a critical need for sex-disaggregated research

Posted: 21 Jun 2022 06:14 AM PDT

A new study reveals that females are 'significantly' more likely to suffer from Long COVID than males and will experience substantially different symptoms.

Science coverage of climate change can change minds

Posted: 20 Jun 2022 12:21 PM PDT

Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue -- but these gains are fragile, a new study suggests.
