Bahamian mosquitofish in habitats fragmented by human activity are more willing to explore their environment, more stressed by change and have smaller brain regions associated with fear response than mosquitofish from unaffected habitats.

After asking white subject to write statements explaining why they weren't prejudiced against Black people, researchers found that other white people could nevertheless gauge the writers' underlying prejudice from linguistic cues--such as dehumanizing language.

An interdisciplinary team of Cornell and Harvard University researchers developed a machine learning tool to parse quantum matter and make crucial distinctions in the data, an approach that will help scientists unravel the most confounding phenomena in the subatomic realm.

Injecting sulphur into the stratosphere to reduce solar radiation and stop the Greenland ice cap from melting. An interesting scenario, but not without risks. Climatologists from the University of Liège (Belgium) have looked into the matter and have tested one of the scenarios put forward using the MAR climate model developed at ULiège. The results are mixed and have been published in the journal The Cryosphere.

You dash into a convenience store for a quick snack, spot an apple and reach for a candy bar instead. Poor self-control may not be the only factor behind your choice, new research suggests. That's because our brains process taste information first, before factoring in health information, according to new research from Duke University.

Only recently researchers have levitated and cooled nanoparticles into the quantum regime. A research team led by Oriol Romero-Isart now proposes a way to harness the quantum properties of such particles before they lose them due to decoherence. To this end, the wave function of the particle is repeatedly expanded and compressed.

Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an "equal pay for equal work" rule when giving resources to partner microbes - except when those microbes underperform.

From above, the Antarctic Ice Sheet might look like a calm, perpetual ice blanket that has covered Antarctica for millions of years. But the ice sheet can be thousands of meters deep at its thickest, and it hides hundreds of meltwater lakes where its base meets the continent's bedrock. Deep below the surface, some of these lakes fill and drain continuously through a system of waterways that eventually drain into the ocean.

Metastatic tumors originating from notoriously aggressive triple-negative breast cancer that emerge in the lungs contain a more diverse array of cancer cells than those that arise in the liver, according to a new study in mice and organs from deceased cancer patients. The study also identified a set of genes that distinguish lung and liver metastases; together, the

A team of MIT and Harvard researchers has developed a modified version of two-photon imaging that can scan deeper within tissue and perform the imaging much faster than previously possible.

Increased acidity in the atmosphere is disrupting the ecological balance of the oceans, according to new research led by the University of East Anglia (UEA). The first study to look at acidity's impact on nutrient transport to the ocean demonstrates that the way nutrients are delivered affects the productivity of the ocean and its ability to absorb CO2 from the atmosphere.

The team presents a new process that uses computational imaging to get high resolution images at a rate 100 to 1,000 times faster than other state-of-the-art technologies that use complex algorithms and machine learning.

Coating ceramic schwarzites, 3D-printed lattices, with a thin polymer helps keep them from shattering under pressure, according to Rice University materials scientists.

Brain microstructure may help explain the benefits of physical activity on cognition in older adults, according to MRI scans of 318 brains post-mortem.

New iguanodon-like dinosaur identified from jawbone fossil from Spain was likely a 6-8m long herbivore, closely related to species found in modern-day China and Niger.

GPS data from cell phones may provide insight into how city inhabitants are using their urban greenspaces, in a study published July 7, 2021 in the open-access journal PLOS ONE by Meghann Mears and Paul Brindley from the University of Sheffield, UK, and colleagues.

Sudanese Islamic burial sites are distributed according to large-scale environmental factors and small-scale social factors, creating a galaxy-like distribution pattern, according to a study published July 7, 2021 in the open-access journal PLOS ONE by Stefano Costanzo of the University of Naples "L'Orientale" in Italy and colleagues.

Uppsala University scientists have designed a new mouse model that facilitates study of factors contributing to the progression of human bladder cancer and of immune-system activation when the tumour is growing. Using this model, they have been able to study how proteins change before, while and after a tumour develops in the bladder wall. The study has now been published in the scientific journal PLOS ONE.

The research sought to uncover the relationship between temperament and eating behaviors in early childhood. The findings are critical because faster eating and greater responsiveness to food cues have been linked to obesity risk in children.

"Droplet-array sandwiching" is a liquid-handling technique in which tiny droplet pairs laid out on opposite surfaces are mixed by bringing the surfaces together. However, this approach is limited to batch operations involving all droplets. Recently, scientists from Ritsumeikan University, Japan, found a way to electrically control the height of individual droplets, allowing them to select which droplet pairs should merge. Their method could replace manual tools such as pipettes and speed up drug screening.
