Beyond Einstein
When stars collapse, they can create black holes, which are everywhere throughout the universe and therefore important to be studied. Black holes are mysterious objects with an outer edge called an event horizon, which traps everything including light. Einstein’s theory of general relativity predicted that once an object falls inside ...
NASA telescopes take a close look at the brightest comet ...
As the brilliant comet 46P/Wirtanen streaked across the sky, NASA telescopes caught it on camera from multiple angles. NASA’s Hubble Space Telescope photographed comet 46P/Wirtanen on Dec. 13, when the comet was 7.4 million miles (12 million kilometers) from Earth. In this visible light image, the comet’s nucleus is hidden ...
Faint glow within galaxy clusters illuminates dark matter
A new look at Hubble images of galaxies could be a step toward illuminating the elusive nature of dark matter, the unobservable material that makes up the majority of the universe, according to a study published online today in the Monthly Notices of the Royal Astronomical Society. Utilizing Hubble’s past ...
Greener days ahead for carbon fuels
For decades, scientists have searched for effective ways to remove excess carbon dioxide emissions from the air, and recycle them into products such as renewable fuels. But the process of converting carbon dioxide into useful chemicals is tedious, expensive, and wasteful and thus not economically or environmentally viable. Now a ...
Data storage using individual molecules
Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the ...
New data show barbershop blood pressure checks remain highly effective
LOS ANGELES — Dec. 17, 2018 — New 12-month data from the Smidt Heart Institute at Cedars-Sinai backs up an earlier study proving that a pharmacist-led, barbershop-based medical intervention can successfully lower blood pressure in high-risk African-American men. The follow-up research was published today in the journal Circulation. “Our initial ...
Tiny implantable device short-circuits hunger pangs, aids weight loss
MADISON, Wis. — More than 700 million adults and children worldwide are obese, according to a 2017 study that called the growing number and weight-related health problems a “rising pandemic.” New battery-free, easily implantable weight-loss devices developed by engineers at the University of Wisconsin-Madison could offer a promising new weapon ...
A damming trend
EAST LANSING, Mich. – Hundreds of dams are being proposed for Mekong River basin in Southeast Asia. The negative social and environmental consequences – affecting everything from food security to the environment – greatly outweigh the positive changes of this grand-scale flood control, according to new research by Michigan State ...
