Researchers combine photoacoustic and fluorescence imaging in tiny package
Mon, 21 Sep 2020 17:05:09 EDT
Researchers have demonstrated a new endoscope that uniquely combines photoacoustic and fluorescent imaging in a device about the thickness of a human hair. The device could one day provide new insights into the brain by enabling blood dynamics to be measured at the same time as neuronal activity.
40% of O'ahu, Hawai'i beaches could be lost by mid-century
Mon, 21 Sep 2020 17:05:07 EDT
The reactive and piecemeal approach historically used to manage beaches in Hawai'i has failed to protect them. If policies are not changed, as much as 40% of all beaches on O'ahu, Hawai'i could be lost before mid-century, according to a new study.
E. coli bacteria offer path to improving photosynthesis
Mon, 21 Sep 2020 17:05:05 EDT
Scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy grail for improving crop yields.
Suspension of fertility treatments during COVID-19 has mental health impacts
Mon, 21 Sep 2020 17:05:03 EDT
The suspension of fertility treatments due to the COVID-19 pandemic has had a variety of psychological impacts on women whose treatments were cancelled, but there are several protective factors that can be fostered to help in the future, according to a new study.
New type of superconductor identified
Mon, 21 Sep 2020 17:05:02 EDT
Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, researchers have discovered a possible third type: g-wave.
Marine sponges inspire the next generation of skyscrapers and bridges
Mon, 21 Sep 2020 17:04:56 EDT
Researchers are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger and taller buildings, longer bridges, and lighter spacecraft. The researchers showed that the diagonally-reinforced square lattice-like skeletal structure of Euplectella aspergillum, a deep-water marine sponge, has a higher strength-to-weight ratio than the traditional lattice designs that have used for centuries in the construction of buildings and bridges.
Low-cost, frequent COVID-19 screening of asymptomatic people could decrease infections, deaths and be cost-effective
Mon, 21 Sep 2020 17:04:54 EDT
When the COVID-19 pandemic is slowing, low-cost, recurring screening of asymptomatic people could decrease infections and deaths and be cost-effective.
2020 Arctic sea ice minimum at second lowest on record
Mon, 21 Sep 2020 17:04:52 EDT
The 2020 minimum extent, which was likely reached on Sept. 15, 2020 measured 1.44 million square miles (3.74 million square kilometers).
Anthropologists compare a composite measure of physiological dysregulation among humans and other primates
Mon, 21 Sep 2020 17:04:51 EDT
It is well understood that mortality rates increase with age. Whether you live in Tokyo, rural Tennessee or the forests of Papua, New Guinea, the older you are, the more likely you are to succumb to any number of different ailments.
Nanoparticle SARS-CoV-2 model may speed drug discovery for COVID-19
Mon, 21 Sep 2020 17:04:48 EDT
Scientists have developed a new tool that mimics how the virus that causes COVID-19 infects a cell, potentially speeding the search for treatments against the disease. The tool is a fluorescent nanoparticle probe that uses the spike protein on the virus surface to bind to cells and trigger the process that pulls the virus into cells. The probe could be used to rapidly gauge how drugs and compounds might block the virus from infecting cells.
Think you have chemical intolerance? Answer three questions
Mon, 21 Sep 2020 17:03:45 EDT
To increase screening of chemical intolerance, researchers have developed and validated a three-question survey that can be incorporated into patient visits within a minute.
Climate: Support for simple funding plans -- even if costs are high
Mon, 21 Sep 2020 15:13:32 EDT
There is growing demand for countries to take aggressive action to combat climate change, but less consensus on how to fund it. In a new study, researchers asked more than 10,000 people from the US, UK, Germany and France to weigh in. The majority preferred a constant-cost plan - even if costs are high. The finding surprised researchers, but provides valuable insight for policymakers.
Long-term COVID-19 containment will be shaped by strength, duration of immunity
Mon, 21 Sep 2020 14:14:54 EDT
New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection, according to a new study.
AI could expand healing with bioscaffolds
Mon, 21 Sep 2020 13:54:07 EDT
Artificial intelligence can speed the development of 3D-printed bioscaffolds that help injuries heal, according to researchers.
How to get a handle on carbon dioxide uptake by plants
Mon, 21 Sep 2020 13:54:05 EDT
How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It's a deceptively complicated question, so a group of scientists recommends combining two cutting-edge tools to help answer the crucial climate change-related question.
Biomarker indicating neurodegeneration identified in the eye
Mon, 21 Sep 2020 13:54:03 EDT
A new study indicates a well-known biomarker that serves as a marker for earlier diagnosis of neurodegenerative diseases is now detectable in the eye. Neurofilament light chain, a protein previously detected in cerebrospinal fluid and blood that is being explored as a biomarker to detect neurodegeneration, has now been identified in the vitreous humor, or fluid within the eye.
Unexpected wildfire emission impacts air quality worldwide
Mon, 21 Sep 2020 13:06:40 EDT
During wildfires, nitrous acid plays a leading role -- spiking to levels significantly higher than scientists expected, driving increased ozone pollution and harming air quality, according to a new study.
