One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed by objects closer to us. Under the right conditions, gravitational lensing can act as a kind of natural telescope, brightening and magnifying the light of distant objects. Astronomers have used this trick to observe some of the most distant galaxies in the universe. But astronomers have also thought about using this effect a little closer to home.

One idea is to ...

Age vs. Genetics: Which is More Important for Determining How we Age?

Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study now shows that individual differences in our DNA matter less as we get older and become prone to diseases of aging, such as diabetes and cancer.

In a study of the relative effects of genetics, aging and the environment on how some 20,000 human genes are expressed, the researchers found that aging and environment are far more important than genetic variation in af...

Method to Fabricate Eco-friendly Adsorbents for Heavy Metal Ion Removal by 3D-Printing

Credit: Environmental Science: Advances

One of the leading causes of water pollution is heavy metal contamination which has profound adverse effects on human health and the environment. That’s why Clarkson University researchers have developed a cost-effective, 3D printing technology to create sustainable bio-based adsorbents that can effectively remove toxic heavy metal ions from contaminated environments. The 3D printing technique offers a cost-effective, scalable and simple approach to creating tunable adsorbents for environmental remediation that can be used broadly by the community for environmental remediation and sensing applications.

The work performed in the laboratory of Professor Silvana Andreescu, the Egon Matijevic Chair in Chemistry, was recently featured on the front ...

Citizen Scientists Enhance New Europa Images from NASA’s Juno

TOP: This pair of images shows the same portion of Europa as captured by the Juno spacecraft’s JunoCam during the mission’s Sept. 29 close flyby. The image at left was minimally processed. A citizen scientist processed the image at right, and enhanced color contrast causes larger surface features to stand out. Credit: Image data: NASA/JPL-Caltech/SwRI/MSSS.
