Evidence of microtubules’ mechanosensitive behavior

Science Daily - 14/10/2021
Direct evidence that microtubules function as mechano-sensors and regulate the intracellular transport of molecules has been reported, leading to new possibilities in the fields of biomechanics, medicine, and biosensors.

Immense set of mysterious fast radio bursts

Science Daily - 13/10/2021
An international team of astronomers recently observed more than 1,650 fast radio bursts (FRBs) detected from one source in deep space, which amounts to the largest set -- by far -- of the mysterious phenomena ever recorded. The source, dubbed FRB 121102, was observed using the Five-hundred-meter Aperture Spherical Telescope (FAST) in China, and represents more FRBs in one event than all previous reported occurrences combined.

Precise measurement of neutron lifetime

Science Daily - 13/10/2021
Physicists have made the most precise measurement of the neutron's lifetime, which may help answer questions about the early universe.

Telehealth addiction treatment rose rapidly during pandemic; but potential benefits still unclear

Science Daily - 13/10/2021
During the COVID-19 pandemic, addiction treatment providers rapidly pivoted to providing services via telehealth. New research highlights the potential for telehealth delivery to increase patient engagement by improving access and convenience. However, it also finds limited evidence that telehealth results in better retention or other outcomes relative to in-person treatment.

COVID testing using pooled samples showed high accuracy, low cost

Science Daily - 13/10/2021
Testing pooled saliva samples twice weekly for SARS-CoV-2 on a residential college campus yielded a greater than 95 percent agreement with the gold standard for accuracy -- nasopharyngeal diagnostic samples tested singly.

Mutations in liver cells linked to liver disease and fat metabolism

Science Daily - 13/10/2021
Mutations linking liver disease with obesity and diabetes have been identified, leading to new understanding about how systemic diseases interact.

Mutated cells drive out early tumors from the esophagus

Science Daily - 13/10/2021
Normal human esophagus carries a high number of mutations, but tumors are rare, due to mutant cells eliminating early tumors.

It’s all in the delivery – Antibodies improve nanoparticle delivery of therapeutic nucleic acids

Science Daily - 13/10/2021
This improved technological platform can be used to develop new treatments, molecular diagnosis strategies or vaccines for various diseases.

Catching malaria evolution in the act

Science Daily - 13/10/2021
Researchers can now detect brand new mutations in individual malaria parasites infecting humans. Such high resolution could help us understand how parasites develop drug resistance and evade immune responses, and suggest potential treatment targets.

Immune system keeps the intestinal flora in balance

Science Daily - 13/10/2021
Trillions of benign bacteria live in the intestine. They are kept in a continuous balance by the immune system, which thereby makes them harmless to humans. Researchers have been able to show how certain natural antibodies keep these bacteria in check. The findings could make an important contribution to the development of superior vaccines.

How many people get 'long COVID'? More than half, researchers find

Science Daily - 13/10/2021
More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms -- more commonly known as 'long COVID' -- up to six months after recovering, according to researchers. The research team said that governments, health care organizations and public health professionals should prepare for the large number of COVID-19 survivors who will need care for a variety of psychological and physical symptoms.

Stress on mothers can influence biology of future generations

Science Daily - 13/10/2021
Biologists have found that mother roundworms can pass stress signals to future generations. The biologists report a mother roundworm exposed to a stressor can even under certain conditions pass the memory of that exposure to their grandchildren.

How the Sun’s magnetic forces arrange gas particles

Science Daily - 13/10/2021
Solar prominences hover above the visible solar disk like giant clouds, held there by a supporting framework of magnetic forces, originating from layers deep within the Sun. The magnetic lines of force are moved by ever-present gas currents -- and when the supporting framework moves, so does the prominence cloud. A research team has observed how magnetic forces lifted a prominence by 25,000 kilometers -- about two Earth diameters -- within ten minutes.

Estimated pulse wave velocity predicts severe COVID

Science Daily - 13/10/2021
Researchers found that estimated Pulse Wave Velocity (ePWV), a readily available marker of arterial stiffness, has been shown to be an effective addition in identifying patients at risk of mortality in hospital due to COVID-19.

Metamaterial eENZ can control correlations of light

Science Daily - 13/10/2021
Researchers have theoretically demonstrated that the correlations of light can be controlled with a metamaterial known as enhanced epsilon-near-zero (eENZ) materials. The material allows small and high-quality lasers that are expected to have applications for example in imaging, flow detection and wireless optical communication.

Scientists develop new strategy that rapidly quantifies transmissibility of COVID-19 variants

Science Daily - 13/10/2021
Researchers have developed a new nanomechanical technique for fast, one-step, immune-affinity tests, which can quantify the immune response induced by different COVID-19 variants in serum. Their technique provides a new tool for tracking infection immunity over time and for analysing new vaccine candidates.

Longstanding magnetic materials classification problem solved

Science Daily - 13/10/2021
For over 100 years, physicists, chemists, and materials scientists have developed extensive theoretical and experimental machinery to predict and characterize the electronic properties of magnetic materials, but even the most successful classification system, developed almost 75 years ago by Lev Shubnikov, was incomplete. An international team of researchers announced this week that it has finally been completed.

Fluorescent spray lights up tumors for easy detection during surgery

Science Daily - 13/10/2021
The prognosis for a cancer patient who undergoes surgery is better if the surgeon removes all of the tumor, but it can be hard to tell where a tumor ends and healthy tissue begins. Now, scientists report that they have developed a fluorescent spray that specifically lights up cancerous tissue so it can be identified readily and removed during surgery.

Primates’ ancestors may have left trees to survive asteroid

Science Daily - 13/10/2021
When an asteroid struck 66 million years ago and wiped out dinosaurs not related to birds and three-quarters of life on Earth, early ancestors of primates and marsupials were among the only tree-dwelling (arboreal) mammals that survived, according to a new study.

Heartburn drugs may have unexpected benefits on gum disease

Science Daily - 13/10/2021
New research found that patients who used drugs prescribed to treat heartburn, acid reflux and ulcers were more likely to have smaller probing depths in the gums (the gap between teeth and gums).
