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 […]

Pollutants in Lakes Linked to Oil Sands

oil-sands-associated-with-increased-levels-of-pollutants

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 […]

Wasp Larva Disinfects Roach From Within

Wasp-Larva-Disinfects-Roach-From-Within

Cockroaches feed on garbage and carrion, so anything that’s devouring a cockroach from the inside out must contend with a variety of disease-causing microbes. Now, German scientists have shown that the larva of the emerald cockroach wasp actively disinfects its roach host by exuding antibacterial chemicals from its mouthparts. The scientists published their findings in […]

28-Foot Ichthyosaur Discovered

ichthyosaur

Researchers have discovered an 8.6-meter long reptile with a massive skull and sharp teeth that lived 244 million years ago, during the Triassic Period. It’s been described as an early ichthyosaur, a four-footed reptile that turned seafarer. The scientists published their findings in the journal Proceedings of the National Academy of Sciences¹. Other ichthyosaurs fed […]

Massive Outburst in Spiral Galaxy NGC 660 Surprises Astronomers

galaxy NGC 660

While using the 305-meter William E. Gordon Telescope at Arecibo, researchers discovered an outburst in spiral galaxy NGC 660 that was ten times brighter than the largest supernova, or exploding star. The surprising discovery of a massive outburst in a neighboring galaxy is giving astronomers a tantalizing look at what likely is a powerful belch […]

Elephants Make the Long Trek Across Deserts for Survival

Elephants Make the Long Trek Across Deserts For Survival

Elephants need to consume a minimum of 100 liters of water and 100 kilograms of vegetation daily, yet a small population of 350 manages to survive in the harsh Gourma region of Mali, south of the Niger River, where temperatures spike to 50˚C and vegetation is sparse. The scientists published their findings in the journal […]

A New Zealand researcher thinks that he has solved the riddle of a mysterious South Pacific island shown on Google Earth and world maps, but which doesn’t really exist. He thinks that a whaling ship from 1876 is to blame. The phantom landmass in the Coral Sea is shown as Sandy Island on Google Earth […]

New research indicates that leaf growth may not be as complicated as it seems. When compared species to species, shorter trees exhibit a greater variety of leaf sizes than taller ones, with the tallest trees all having leaves that measure 10 to 20 centimeters in length. The scientists published their findings in the journal Physical […]
