Tiny particles in blood useful for early diagnosis of pancreatic cancer

Researchers at MD Anderson Cancer Center have identified a potential non-invasive diagnostic tool for early pancreatic cancer detection. Glypican-1-enriched circulating exosomes were found to be present in small amounts of serum from patients with pancreatic cancer, showing high specificity and sensitivity. Early detection of pancreati...

Giving atoms their marching orders

Scientists at the University of South Carolina and University of Florida have created a new system for studying gas flow in narrow tubes with single-file atom movement. By comparing these nanotubes to wider tubes, researchers aim to understand fundamental processes involved in gas separation and membrane technology.

Eavesdropping on the body: New device tracks chemical signals within cells

Researchers at the University of Toronto have developed a new device that can track chemical signals within cells, allowing for faster and more accurate detection of cancerous growth. The device uses digital microfluidics to deliver rapid sequences of chemicals, enabling scientists to study cell responses in unprecedented detail.

Artifical neuron mimicks function of human cells

Scientists at Karolinska Institutet have created an organic bioelectronic device that can receive chemical signals and relay them to human cells, mimicking the function of a human nerve cell. This innovation has the potential to improve treatments for neurological disorders by bypassing damaged nerve cells.

How the brightest lights in the universe 'flicker'

Astronomers discover active galactic nuclei (AGN) exhibit flickering behavior, switching on and off every 200,000 years. This phenomenon affects star formation in host galaxies, with radiation from AGN potentially delaying or preventing the collapse of gas clouds.

University of Illinois awarded $3.1 million to develop all-terrain rovers for high-throughput field phenotyping

The University of Illinois will lead a $3.1 million project to develop all-terrain automated ground rovers for high-throughput field phenotyping. These rovers will measure crop growth using 3-D reconstruction and various sensors, enabling faster breeding of energy sorghum and other bioenergy crops.

Diabetic blindness: UVA IDs best source of stem cells to block vision loss

Researchers have evaluated the best potential sources for adult stem cells to be used for treating diabetic retinopathy. They found that cells taken from donors without diabetes are more effective than those from patients' own bodies. This discovery provides a crucial framework for evaluating stem cells for future treatments.

Medical research not addressing patient and clinician priorities

A recent study published in Research Involvement and Engagement found that research on treatments for health problems like diabetes and schizophrenia is not focused on the most important treatments considered by patients and clinicians. The study reveals marked differences between the types of treatments highlighted as priorities by pa...

Researchers reconstruct dinosaur tracks

Researchers reconstructed dinosaur tracks at a 154-million-year-old quarry site, suggesting carnivorous dinosaurs hunted herbivorous island-dwelling dinosaurs. The digital model reveals that the predators could have immigrated via a land bridge as sea levels dropped.

University of Iowa studies impact of marijuana on driving

A new study conducted at the University of Iowa's National Advanced Driving Simulator found that drivers who use both alcohol and marijuana together weaved more on a virtual roadway than those using either substance independently. The study, which analyzed the effects of inhaled cannabis on driving performance, also found no double eff...

The pertussis pathogen -- New findings

Researchers discovered that the protein structure of a key membrane protein differs from a previously postulated model, providing a basis for new treatments. The study reveals how the protein pore opens and closes in response to substrate binding, offering insights into the pathogen's attachment mechanism.

Commodity market volatility more perception than reality

Researchers found that commodity price bubbles were short-lived and not as frequent as thought. Bubbles in the grain markets occurred more often during periods of production problems rather than speculative activity. The study's findings suggest that the commodity market is doing a good job of accessing prices, with only minor hiccups.

'Pick and mix' smart materials for robotics

Scientists at the University of Cambridge developed a method to combine multiple functions in a single material by integrating structure at the nanoscale. This approach enables the creation of multi-functional artificial muscles that can move, sense, and report on their environment.

Biomanufacturing of CdS quantum dots

A team of Lehigh University engineers has developed a novel approach for the reproducible biosynthesis of extracellular, water-soluble quantum dots using bacteria and cadmium sulfide. This method reduces cost and environmental impact by utilizing an engineered strain of Stenotrophomonas maltophilia to control particle size.

The shame of psychology

UCSB sociologist Thomas Scheff argues that psychology's scientific method is blind to the insights of intuition, leading to misconceptions about catharsis, stigma, and self-esteem. Future studies could split scales into cognitive and emotional components to address these issues.
