A lab that specializes in applying data science to the study of conservation biology has created an open-source app to harvest field data from Microsoft's HoloLens mixed-reality headset. The app allows researchers to gather data as they walk and look at vegetation. Spatial data is displayed on the HoloLens screen in real time and can be stored for later analysis.

As plants experience multiple stressors from heat, drought and flooding because of extreme weather events, a plant scientist recently discovered a new way of measuring whether they are stressed out.

New research provide evidence that the crustacean carapace, along with other plate-like structures in arthropods (crustaceans, insects, arachnids, and myriapods) all evolved from a lateral leg lobe in a common ancestor more than 500 million years ago. This work further supports their proposal for a new concept of how novel structures evolve -- one which suggests that they aren't so novel, after...

By the year 2060, projected rates of cardiovascular risk factors and disease will increase significantly in the United States, according to a new study.

In the classic 'nature versus nurture' debate, scientists discovered ancient ice ages have shaped the genetics of eelgrasses today -- and those genetics could play a stronger role than the environment in shaping how eelgrasses respond to threats.

Using digital devices, such as smartphones, could help improve memory skills rather than causing people to become lazy or forgetful, finds a new study.

SARS-CoV-2 causes a broad range of clinical symptoms, including potentially fatal acute respiratory distress syndrome (ARDS). A study suggests the nasal epithelium (the lining of the nose) of children inhibits infection and replication of the ancestral strain of the SARS-CoV-2 virus and the Delta variant, but not the Omicron variant.

Depictions of women in science, technology, engineering and mathematics (STEM) are powerful sources of inspiration for young women who aspire to a career in those fields. But stereotypes of female scientists persist, and we have some way to go to vanquish them, say the authors of a new paper.

New research introduces a novel, AI-based dynamic brain imaging technology alternative which could map out rapidly changing electrical activity in the brain with high speed, high resolution, and low cost.

Researchers report that individuals with two copies of a gene mutation show evidence of substantial iron buildup in regions of the brain, raising risk for movement disorders like Parkinson's disease.

Engineers have created a way to 3D print large and complex parts at a fraction of the cost of current methods.

Researchers have identified a group of molecules that enable cells to repair damaged components, making it possible for those tissues to retain proper function.

Cystic fibrosis (CF) is caused by a mutation of the CFTR gene. While there are many hundreds of known mutations, not all of them are currently treatable which means a significant number of CF patients lack targeted therapies. In an effort to identify new treatments for these patients, researchers from Boston University School of Medicine (BUSM) set out to use blood cells from individuals with CF...

When a dog starts a new diet, the community of microbes in its gut changes. Wallflower bacteria multiply to dominate the scene, with the old guard slinking off in defeat. As microbial species jostle for control, their metabolic byproducts, many of which are critical for Fido's overall health, change as well. The dynamic dance between nutrients, microbes, and their chemical products is well...

Since the 1800s, scientists have observed the configuration of centromeres -- a special chromosomal region that is vital during certain types of cell division -- in the nucleus. Up until this point, however, the determining mechanisms and the biological significance of centromere distribution were poorly understood. A team has recently proposed a two-step regulatory mechanism that shapes...

A new study shows serious smoking cessation activity declined among adults in the United States immediately after the onset of COVID-19 and persisted for over a year. Declines in attempts to quit smoking were largest among persons experiencing disproportionately negative outcomes during COVID-19, including Black people, people with comorbidities, middle-aged people, and lower educated people.

SARS-CoV-2 variants of concern and the biological sex of patients affect the efficacy of molnupiravir, the first orally available drug approved for outpatient use against COVID-19, according to a new study.

Black people and women with severe heart failure who might be good candidates for surgery to implant a heart-assisting device have a lower chance of actually getting that operation than white patients, or male patients, a new study finds.

CD8+ regulatory-like T cells reach the brain within 24 hours after stroke onset, where they release molecules that provide direct neuroprotective effects, as well as limit inflammation and secondary brain damage.

A new technique opens a door to manufacturing of pressure-monitoring bandages, shade-shifting fabrics, or touch-sensing robots

The pandemic reduced Native American life expectancy at birth from the already low 72 years in 2019 to about 67 years in 2020 and about 65 years in 2021 for both sexes combined.

Scientists embedded elementary particles called muons into a many-layered nickel oxide superconductor to learn more about its magnetic properties. They discovered that waves of flip-flopping electron spins create magnetic excitations that sweep through the nickel layer of the compound whether it's superconducting or not. This is in sharp contrast to what happens in the best-known family of...

All human tumors originating from various tissues share a series of properties that define them, including the ability to prevent cell death. Instead, healthy organs induce programmed cell death or apoptosis to balance their size and eliminate damaged cells. There is a specific and physiological cell death called ferroptosis that occurs induced by the oxidation of fat mediated by iron content.

For a long time, our view of Ceres was fuzzy, according to a geoscientist. A dwarf planet and the largest body found in the asteroid belt -- the region between Jupiter and Mars speckled with hundreds of thousands of asteroids -- Ceres had no distinguishable surface features in existing telescopic observations from Earth.
