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.

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.

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.

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.

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.

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...

When the COVID-19 pandemic is slowing, low-cost, recurring screening of asymptomatic people could decrease infections and deaths and be cost-effective.

The 2020 minimum extent, which was likely reached on Sept. 15, 2020 measured 1.44 million square miles (3.74 million square kilometers).

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.

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...

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.

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.

After a mental illness episode, less than half of children received any therapy within three months, and 22.5% of children received only drug therapy, according to a new study.

New research overturns current scientific thinking on flu infection in pregnancy. The study helps explain why influenza can lead to life-threatening complications during pregnancy. The research also has implications for our understanding of how COVID-19 may be affecting the vascular system.

A team of researchers has revealed why male funnel web spiders develop much deadlier venom than their female counterparts. The team has spent 20 years investigating delta-hexatoxins, the venom peptides that make funnel web spider venom so dangerous.

In the United States, fully stocking non-stocked and poorly stocked forests would result in an annual increase of 20 percent in the amount of carbon sequestered by forests.

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.

Artificial intelligence can speed the development of 3D-printed bioscaffolds that help injuries heal, according to researchers.

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.

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.

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.

When the COVID-19 pandemic first began, many non-urgent surgeries were delayed. Now, a new paper explains how to address the backlog of surgeries, without compromising patient outcomes.

A study of search and rescue dogs showed little difference in longevity or cause of death between dogs at the disaster site and dogs in a control group.

Scientists have used new techniques to create a composite that increases the electrical current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense electric vehicle traction motors.
