DURHAM, N.C. -- Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could prove useful to applications in optics, plasmonics, electronics and multi-stage chemical catalysis.

The novel approach appeared online on March 25 in the journal ACS Nano.

Populations with a high prevalence of AIDS-immunocompromised people are more likely to see the emergence of antibiotic-resistant bacterial infections, according to a study coauthored by researchers at the University of Tennessee, Knoxville, and published in PLOS One.

The dark brown melanin pigment, eumelanin, colors hair and eyes, and protects our skin from sun damage. It has also long been known to conduct electricity, but too little for any useful application - until now.

In a landmark study published in Frontiers in Chemistry, Italian researchers subtly modified the structure of eumelanin by heating it in a vacuum.

People in many parts of the world feed birds in their backyards, often due to a desire to help wildlife or to connect with nature. In the United States alone, over 57 million households feed backyard birds, spending more than $4 billion annually on bird food.

While researchers know that bird feeding can influence nature, they do not know how it influences the people who feed those birds.

COLUMBUS, Ohio - Researchers with The Ohio State University College of Medicine and The Ohio State University Wexner Medical Center have identified a metabolic process in the heart that, if treated, could someday prevent or slow the progression of heart failure.

The American Heart Association journal Circulation published the findings today.

Before any physical signs or symptoms of heart failure are present, the first maladaptive changes occur in cardiac cell metabolism - how the heart fuels itself to pump blood through the body constantly.

SYRACUSE, N.Y. - Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding of the structure of matter in the universe.

Prostate cancer cells change the behaviour of other cells around them, including normal cells, by 'spitting out' a protein from their nucleus, new research has found.

The tiny pieces of protein are taken up by the other cells, provoking changes that promote tumour growth and - the researchers believe - help the cancer hide from the body's immune system.

NASA calculated the rainfall rates occurring in Tropical Cyclone Joaninha as it moved through the open waters of the Southern Indian Ocean.

Data from the Global Precipitation Measurement mission (GPM) is used to develop rainfall total estimations and provided a look at rain Joaninha was generating.

A machine-learning model from MIT researchers computationally breaks down how segments of amino acid chains determine a protein's function, which could help researchers design and test new proteins for drug development or biological research.

Physicists in the United States, Austria and Brazil have shown that shaking ultracold Bose-Einstein condensates (BECs) can cause them to either divide into uniform segments or shatter into unpredictable splinters, depending on the frequency of the shaking.

NEW ORLEANS--Exposure to dim light at night, which is common in today's lifestyle, may contribute to the spread of breast cancer to the bones, researchers have shown for the first time in an animal study. Results of the study will be presented Saturday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

NEW ORLEANS--For migraine sufferers with obesity, losing weight can decrease headaches and improve quality of life, researchers from Italy and the United States report. The results of their meta-analysis will be presented Saturday, March 23 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

A new system devised by researchers at MIT can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a Coast Guard cutter, the system pinpointed a motor with burnt-out wiring that could have led to a serious onboard fire.

A new lightweight, low-profile and inexpensive ankle exoskeleton could be widely used among elderly people, those with impaired lower-leg muscle strength and workers whose jobs require substantial walking or running.

Developed by Vanderbilt mechanical engineers, the device is believed to be the first ankle exoskeleton that could be worn under clothes without restricting motion. It does not require additional components such as batteries or actuators carried on the back or waist.

Scientists at Winship Cancer Institute of Emory University, Children's Healthcare of Atlanta and Georgia Tech have found that modulating blood-forming stem cells' stiffness could possibly facilitate mobilization procedures used for stem cell-based transplants.

Temporary squishiness could help drive blood-forming stem cells out of the bone marrow and into the blood, but the cells need to be stiff to stay put and replenish the blood and immune system, the researchers have found. The results from animal research were published on March 14 in the journal Cell Stem Cell.
