Drugs found to both prevent and treat Alzheimer's disease in mice
Researchers have found that a class of pharmaceuticals can both prevent and treat Alzheimer's disease in mice.
Allosaurus fed more like a falcon than a crocodile: Engineering, anatomy work reveals differences in dinosaur feeding styles
The mighty T. rex may have thrashed its massive head from side to side to dismember prey, but a new study shows that its smaller cousin Allosaurus was a more dexterous hunter and tugged at prey more like a modern-day falcon.
Glaucoma drug can cause droopy eyelids
Prostaglandin analogues (PGAs) are often the first line of treatment for people with glaucoma. PGAs have long been associated with blurred vision, dryness, changes in eye color and other side effects. Now a new study has found that these drugs also cause upper and lower eyelid drooping and other issues that can interfere with vision.
New method for tailoring optical processors
Physicists and engineers have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color.
Evaluating a new way to open clogged arteries
A new study analyzes the potential usefulness of a new treatment that combines the benefits of angioplasty balloons and drug-releasing stents, but may pose fewer risks.
Common food supplement fights degenerative brain disorders, study suggests
Widely available in pharmacies and health stores, phosphatidylserine is a natural food supplement produced from beef, oysters, and soy. Now scientists have discovered that the supplement improves the functioning of genes involved in degenerative brain disorders, including Parkinson's disease and familial dysautonomia.
Scientists uncover how grapefruits provide a secret weapon in medical drug delivery
Researchers have uncovered how to create nanoparticles using natural lipids derived from grapefruit, and have discovered how to use them as drug delivery vehicles.
NASA’s BARREL mission launches 20 balloons
In Antarctica in January, 2013 -- the summer at the South Pole -- scientists released 20 balloons, each eight stories tall, into the air to help answer an enduring space weather question: when the giant radiation belts surrounding Earth lose material, where do the extra particles actually go?
NASA's IRIS mission readies for a new challenge
NASA is getting ready to launch a new mission, a mission to observe a largely unexplored region of the solar atmosphere that powers its dynamic million-degree outer atmosphere and drives the solar wind. In late June 2013, the Interface Region Imaging Spectrograph, or IRIS, will launch from Vandenberg Air Force Base, Calif. Show More Summary
Single-cell transfection tool enables added control for biological studies
Researchers have developed a novel tool for single-cell transfection, in which they deliver molecules into targeted cells through temporary nanopores in the cell membrane created by a localized electric field.
Radioactive nanoparticles target cancer cells
Researchers have found a way to create radioactive nanoparticles that target lymphoma tumor cells wherever they may be in the body.
Abundance and distribution of Hawaiian coral species predicted by model
Researchers have developed species distribution models of the six dominant Hawaiian coral species around the main Hawaiian Islands, including two species currently under consideration as threatened or endangered.
Magnetic fingerprints of superfluid helium-3
Superconducting sensors have allowed for highly sensitive measurements of the nuclear magnetic resonance of thin helium-3 layers.
Fourteen closely related crocodiles existed around 5 million years ago
Today, the most diverse species of crocodile are found in northern South America and Southeast Asia: As many as six species of alligator and four true crocodiles exist, although no more than two or three ever live alongside one another at the same time. Show More Summary
A tiny programmable fly's eye
A novel curved artificial compound eye (CurvACE) has been created. Compared to single-lens eyes, compound eyes offer lower resolution, but significantly larger fields of view, thin package, and with negligible distortion.
Visual search function: Where scene context happens in our brain
Though a seemingly simple and intuitive strategy, visual search function -- a process that takes mere seconds for the human brain -- is still something that a computer can't do as accurately. Over the millennia of human evolution, our brains developed a pattern of search based largely on environmental cues and scene context. Show More Summary
How to best manage workaholics: New study offers insight
Workaholics tend to live in extremes, with great job satisfaction and creativity on the one hand and high levels of frustration and exhaustion on the other hand. Now, a new study offers managers practical ways to help these employees stay healthy and effective on the job.
How gold nanoparticles can help fight ovarian cancer
Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Researchers found out why and determined how to make the nanoparticles effective against ovarian cancer cells.
Geochemist aids development of geologic time scale for study of Earth's history
The Geologic Time Scale 2012, or GTS2012, is the latest understanding of Earth's history, and the means by which geoscientists around the world investigate the rock record.
Elusive search for biomarkers in Huntington's disease
While Huntington's disease (HD) is currently incurable, the HD research community anticipates that new disease-modifying therapies in development may slow or minimize disease progression. The success of HD research depends upon the identification...Show More Summary
