Space Plants Will future astronauts be able to snack on fresh space-grown produce? New research is advancing the study of plant growth in space, which may one day support humans living and growing their own food in space or on the surface of Mars. Researchers at the University of Florida Space Plants Lab are analyzing tissue taken from plants that have spent their entire lives growing in the microgravity environment aboard the International Space Station. It's revealing that plants can ind ...read more

Two astronomers have devised a method that lets them “see” dark matter with the light from rogue stars. The pair has shown how images of faint starlight taken with the Hubble Space Telescope can be used to map dark matter’s distribution in galaxy clusters. The novel technique could ultimately help explore the nature of dark matter. Dark matter remains one of the great mysteries of modern science. A theoretical form of matter, dark matter is thought to make up about 8 ...read more

Food. It's probably on your mind quite a bit this holiday season, whether you're anticipating festive meals or dreading the pounds you might pack on during a bout of epicurean overindulgence. Though tips on managing our cravings for all things sweet and fatty abound, it's also worth remembering that the odds are stacked against us when it comes to resisting the call of another slice of pie. Our brains respond to food, and even the sight or thought of it, with a heady rush of chemicals ...read more

In Indonesia, they call it "Anak Krakatoa, meaning "child of Krakatoa." It's a volcano that rose from the sea in the 1920s decades after one of the most deadly volcanic cataclysms in recorded history killed tens of thousands of people and all but obliterated the island of Krakatoa, east of Java. Now, Anak Krakatau has itself brought great misery to Indonesia, with an eruption that apparently triggered an underwater landslide, which in turn sent a tsunami raci ...read more

Some two billion years ago, the first photosynthetic algae evolved the ability to respond to light—the brilliant Sun by day, the spectral Moon by night. Around 700 million years ago, primitive eye-pits appeared; then, during the Cambrian era, arthropod-like creatures gazed at the sky through true eyes, sensing the lunar rising and setting with their arthropod-like comprehension. So it continued, into the succeeding chapters of life featuring mammals, primates, hominins, and Homo sapiens, t ...read more

"Earthrise" was taken 50 years ago this Christmas, and it’s one of the most — if not the most — iconic images of the 20th century. It’s the image that gave us the idea that we went to the Moon and discovered the Earth. But there are so many other firsts that Apollo 8 brought us, so I thought we ought to take a minute to look at some of the less celebrated but still absolutely incredible images from Apollo 8.   But First, Who Took That Iconic Apollo 8 Earthri ...read more

A new vent opened today on Etna in Sicily with lava flows and an ash plume from the new vent near the Southeast Crater. The eruption started after over 100 earthquakes up to M4 rattled the volcano on December 24. People (mostly skiers) on the volcano were evacuated as the eruption began. The ash plume from the eruption prompted the airspace around Catania to close as well. From the look of the ash plume, some is being produced by the eruption but part of the plume may be coming from the inte ...read more

For the second time this year, an unexpected tsunami hit the coast of Indonesia resulting in hundreds of deaths. This tsunami may have been generated by an eruption of Anak Krakatau in the Sunda Strait, with Indonesian officials speculkating that an erupotion that occurred late last night may have triggered undersea landslides. So far, at least 220 people are known to have died , over 800 were injured and multitudes are missing. Many of the deaths were in Pandelang, located at the end of bay ...read more

Do you believe that people's eyes emit an invisible beam of force? According to a rather fun paper in PNAS, you probably do, on some level, believe that. The paper is called Implicit model of other people’s visual attention as an invisible, force-carrying beam projecting from the eyes. To show that people unconsciously believe in eye-beams, psychologists Arvid Guterstam et al. had 157 MTurk volunteers perform a computer task in which they had to judge the angle at which paper tubes wou ...read more

Astronomers have discovered a bizarre, Neptune-sized exoplanet located less than 100 light-years from Earth that's shedding its atmosphere so quickly it may help researchers finally answer the long-standing question: Where did all the hot Neptunes go? According to the new research, published December 13 in the journal Astronomy and Astrophysics, the shrinking world, named GJ 3470b, is rapidly losing its atmosphere as it's bombarded by a steady stream of energetic charged particle ...read more
