Hubble Has Had 25 Exciting Years

April 24, 2015 9:35 am | by Seth Augenstein, Digital Reporter | News | Comments

The Hubble Space Telescope, launched 25 years ago today, has had its fair share of dramatic turns. Now, a series of events are planned across the country to commemorate what eventually, after several false starts and problems, turned out to be one of NASA’s signature achievements.  


Link Discovery May Be Key to Fighting Alzheimer's

April 24, 2015 7:00 am | by Univ. of Cambridge | News | Comments

Researchers have identified how proteins that play a key role in Alzheimer’s disease are linked in a pathway that controls its progression, and that drugs targeting this pathway may be a potential new way of treating the disease.


Chemists Isolate Silicon Oxides

April 24, 2015 7:00 am | by Univ. of Georgia | News | Comments

In an effort that reaches back to the 19th century laboratories of Europe, a discovery by chemistry researchers establishes new research possibilities for silicon chemistry and the semiconductor industry. The study gives details on the first time chemists have been able to trap molecular species of silicon oxides.


Nanoscale Blocks, DNA 'Glue' Shape 3-D Superlattices

April 24, 2015 7:00 am | by Brookhaven National Laboratory | News | Comments

Taking child's play with building blocks to a whole new level— the nanometer scale— scientists have constructed 3-D "superlattice" multicomponent nanoparticle arrays where the arrangement of particles is driven by the shape of the tiny building blocks. The method uses linker molecules made of complementary strands of DNA to overcome the blocks' tendency to pack together in a way that would separate differently shaped components.


X-rays Key to Better Blood Pressure Drugs

April 24, 2015 7:00 am | by SLAC National Accelerator Laboratory | News | Comments

An experiment has revealed, in atomic detail, how a hypertension drug binds to a cellular receptor that plays a key role in regulating blood pressure. The results could help scientists design new drugs that better control blood pressure while limiting side effects.


Computer Vision Sees Tiny Vibrations in Bridges, Buildings

April 24, 2015 7:00 am | by MIT, Jennifer Chu | Videos | Comments

To the naked eye, buildings and bridges appear fixed in place, unmoved by forces like wind and rain. But in fact, these large structures do experience imperceptibly small vibration. Now, researchers have developed a technique to “see” vibrations that would otherwise be invisible to the naked eye, combining high-speed video with computer vision techniques.


New Genomes Bring Mammoths One Step Closer to Resurrection

April 24, 2015 7:00 am | by Associated Press, Malcolm Ritter | News | Comments

Scientists are getting their best look yet at the DNA code for the woolly mammoth, thanks to work that could be a step toward bringing back the extinct beast. Researchers deciphered the complete DNA code, or genomes, of two mammoths. The new genomes are far more refined than a previous one announced in 2008.


Women are Missing in STEM Fields

April 24, 2015 7:00 am | by Lily Barback, Associate Editor | Blogs | Comments

At the age of eight, 66 percent of girls say they like math yet, in college, only 18 percent of women study engineering. By adulthood, while they compose half the population and half the workforce, only a quarter of STEM positions are held by women. Not only is this a problem— it’s a worsening one.


Pollution Shrinks Brains, Causes Silent Strokes

April 23, 2015 4:01 pm | by Seth Augenstein, Digital Reporter | News | Comments

Fine-particle air pollution can cause damage to brain structures over long-term exposure. It can shrink brains, lead to cognitive problems and even cause silent stokes, according to new research.


Fossilized Teeth Reveal Evolution of Stem Cells

April 23, 2015 3:00 pm | by UC San Francisco | News | Comments

All currently existing rodent species have ever-growing front teeth, but only some species have continuously growing molars. Ever-growing teeth are possible because of stem cell reservoirs at the root of each tooth that continuously create the crown. By studying fossilized teeth from thousands of extinct rodent species, scientists have shown how fundamental evolutionary mechanisms drive the emergence of novel mammalian stem cells.


Model Predicts Flow Patterns

April 23, 2015 3:00 pm | by MIT, Jennifer Chu | News | Comments

Drizzling honey on toast can produce mesmerizing, meandering patterns, as the syrupy fluid ripples and coils in a sticky, golden thread. Dribbling paint on canvas can produce similarly serpentine loops and waves. Now, a group of mathematicians has developed a simple model to predict patterns formed by viscous fluids as they fall onto a moving surface.


Gender Difference Seen in Stegosauruses

April 23, 2015 3:00 pm | by Univ. of Bristol | News | Comments

A new study has found that tall-plated Stegosaurus and the wide-plated Stegosaurus were not two distinct species, nor were they individuals of different age: they were actually males and females. This is the first convincing evidence for sexual differences in a species of dinosaur.


Wellness Advocate, Bestselling Author: I Faked Cancer

April 23, 2015 2:04 pm | by Seth Augenstein, Digital Reporter | News | Comments

A woman who became a bestselling author and wellness advocate after she claimed she healed herself of a brain tumor through a healthy diet admitted she never had cancer, according to a magazine investigation published this week.


Tech Links Blue Bell to Older Listeria Illnesses

April 23, 2015 12:47 pm | by Associated Press, Mary Jalonick | News | Comments

The government is relying on some new technology to track an outbreak of life-threatening listeria linked to Blue Bell ice cream products. Now, federal and state officials have realized the outbreak was not just a recent event— the ice cream had likely made people sick since 2010. It gives officials hope that future outbreaks can be tracked faster, and more accurately.
