New research indicates that happier people actually earn more money. This comes as a result of a study of 10,000 Americans that showed that those who experienced more positive daily emotions and felt more satisfied with their lives while growing up, earned more income by age 29. The scientists published their findings in the journal […]

The phenomenon of cathodoluminescence gave geologists an easy way to identify quartz and other minerals in rock samples. Cathodoluminescence allows a piece of quartz to glow icy blue when put under an electron scanning microscope. Now, scientists have used this phenomenon to probe into nanostructures. The scientists published their findings in the journal Physical Review […]

Hubble & Spitzer See Weather Patterns in a Brown Dwarf

Weather-Patterns-in-Brown-Dwarf

By using the Hubble Space Telescope and Spitzer Space Telescope to simultaneously view the brown dwarf planet 2MASSJ22282889-431026, a team of astronomers has created a detailed “weather map” and a technique to better understand the atmospheres of planets beyond our solar system. Pasadena, California — Astronomers using NASA’s Spitzer and Hubble space telescopes have probed […]

Scientists have discovered the reason why the skin on human fingers and toes shrivels up when soaked in water. Laboratory tests confirmed that wrinkly fingers improve the grip on wet or submerged objects, working away the water like rain treads in car tires. The scientists published their findings in the journal Biology Letters¹. People wrongly […]

Possible Planetary Disasters That Could Cause Extinction

Planetary-Disasters-That-May-Cause-Extinction

In the last 40,000 years, there have been at least ten gigantic landslides of more than 100 cubic kilometers in the North Atlantic ocean alone. Each of these was capable of producing waves tens to hundreds of meters in height and according to a new report, this is only one of the many possible planetary […]

Cyanobacteria Engineered to Make Raw Materials for Fuels from Sunlight

Cyanobacteria,-or-blue-green-algae

In a newly published study, UC Davis scientists detail how they engineered cyanobacteria to grow chemical precursors for fuels and plastics, taking a step forward in establishing independence from fossil reserves. Chemists at the University of California, Davis, have engineered blue-green algae to grow chemical precursors for fuels and plastics — the first step in […]

Hubble Reveals 2,000 Year Long Elliptical Orbit for Fomalhaut B

Hubble-Reveals-Rogue-Planetary-Orbit-For-Fomalhaut-B

A new Hubble image has allowed scientists to calculate the orbital motion of the planet Fomalhaut b, finding that the orbit takes the planet as close as 4.6 billion miles to the star and as far as 27 billion miles away from the star during the 2,000 year-long elliptical orbit. Newly released NASA Hubble Space […]

Some of the world’s largest reserves of crude oil are held in the oil sands in Alberta, Canada, and production has been ongoing. A new study shows that contaminants from the development of the sands are stacking up in the environment. The scientists published their findings in the journal Proceedings of the National Academy of […]

Graphene Oxide Removes Radioactive Material from Water

Graphene-oxide-soaks-up-radioactive-waste

A newly published study has shown that graphene oxide can rapidly remove some of the most toxic and radioactive long-lived human-made radionuclides from contaminated water, providing a simple methodology to reduce nuclear waste contamination and help speed up removal. Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at […]

Gene-Expression Indicates How Coral Reefs Will Handle Climate Change

Gene-Expression-Indicates-How-Coral-Reefs-Will-Handle-Climate-Change

Scientists have discovered a pattern of gene activity, which allows some corals to survive in higher temperatures. This suggests a way to predict how different corals will react to warmer waters, which are expected to result from climate change over the coming decades. The scientists published their findings in the journal Proceedings of the National […]

Brainless Slime Mold Physarum polycephalum Shows Intelligence

physarum-polycephalum-silme-mold

Slime molds are gelatinous amoebae that are classified as protists, a taxonomic group. Slime molds, while brainless, are smarter than they look. Physarum polycephalum can solve mazes, mimic the layout of man-made transportation networks, and choose the healthiest food from a menu. P. polycephalum rummages through leaf litter and oozes along searching for bacteria, fungal […]

Health Problems Future Mars Astronauts May Face

Mars500-experiment

A newly published study found that astronauts going to Mars could have trouble sleeping, become lethargic, and have problems with mental tasks over the course of a long mission. The Mars 520-d experiment is an international test run by the Russian Academy of Science, in conjunction with the ESA and the Chinese space agency. The […]

Tuscan Shipwreck Gives Clues of Ancient Eye Treatment

Ancient-Eye-Treatment-Recovered-From-Shipwreck

Archaeologists have retrieved medicinal tablets from a 2000-year old shipwreck, indicating that classical Mediterranean civilizations used sophisticated drugs. The scientists published their findings in the journal Proceedings of the National Academy of Sciences¹. The merchant ship Relitto del Pozzino sank off the coast of Italy in 130 BCE. Archaeological excavations in 1989 and 1990 yielded […]
