- Mars, moon, and star form brilliant sky triangle tonight
The moon, Mars and the star Regulus will combine to form a very bright triple play Tuesday night.
- How do supermassive black holes get so big? A peculiar diet, perhaps.
New research suggests that the supermassive black holes at the cores of some galaxies could grow so large by consuming one star from a binary system and flinging the other into space.
- Human ancestors used fire a million years ago, finds study
Ash and a charred bone unearthed in South Africa indicates that, even a million years ago, humanity's forebears had harnessed fire.
- Jet-airliner-sized April Fools' Day asteroid buzzes Earth
About 150 feet wide, asteroid 2012 EG5 hurtled past our planet Sunday, passing closer than the moon.
- Global warming began in oceans 135 years ago, suggests study
A study of temperature recordings from the 1870s suggests that the oceans began warming more than 100 years ago, much earlier than previously believed.
- Planets found at dawn of universe, but their existence is a mystery
Scientists have found two planets orbiting a star that formed only a billion years after the big bang. But the universe had few planet-making elements then, so how did the planets form?
- Head of 'faster-than-light' neutrinos team resigns
Italy's National Institute of Nuclear Physics said Friday that Antonio Ereditato had stepped down from the leadership of the OPERA experiment, whose measurements on the speed of neutrinos were widely questioned when they were announced in September.
- Are bees threatened by insecticide use? New studies say yes.
Scientists found that one class of insecticides may harm both bumblebees and honeybees in two recent studies. Bees' important role as pollinators may be threatened.
- Are pesticides responsible for bee deaths?
Important pollinators, both bumblebees and honeybees have trouble functioning after being exposed to pesticides, two new studies say. Industry experts question several aspects of the work.
- How did humans evolve to walk upright? Fossil discovery complicates the picture.
Foot bones unearthed recently in Ethiopia belonged to a contemporary of 'Lucy,' the 3.2-million-year-old early human discovered in 1974. But these bones seem to belong to a different species, one thought to have split its time between walking upright and climbing trees.
- Amazon's Jeff Bezos to search for sunken Apollo 11 engines
Amazon CEO Jeff Bezos says that his deep-sea sonar expedition in the Atlantic has located the five engines used to launch Neil Armstrong, Buzz Aldrin, and Michael Collins to the moon in 1969, and he plans to bring at least one of them to the surface.
- US Army tests robot that can jump 30 feet high
Developed by Boston Dynamics and Sandia National Labs, the Sand Flea reconnaissance robot can leap through a second-floor window.
- Fossil discovery could unravel mystery of how humans learned to walk
The discovery of foot bone fossils from an early hominin may help unlock the mystery of how humans learned to walk upright.
- How thoughtful farming could curb climate change, feed the world
Policy makers may begin to address climate change by encouraging sustainable agriculture practices around the world, according to a new report.
- Fossil find sheds light on how humans evolved to walk
A discovery in Ethiopia of 3-million-year old foot bones that once belonged to a human relative suggests that human bipedalism evolved more than once.
- Climate change report: Watch out Mumbai and Miami
A new climate change report says parts of Mumbai, India, could become uninhabitable from floods, storms and rising seas. Other coastal ciies, such as Miami, are also at risk from rising seas.
- Astronomers say that there are billions of potentially habitable planets in our galaxy
A team of European astronomers say that about 40 percent of red dwarf stars - the most common type of star in the Milky Way - have at least one planet whose temperatures would allow liquid water on the surface.
- Study indicates existence of billions of habitable alien planets in Milky Way
A survey of red dwarf stars suggests that, in our galaxy alone, there are tens of billions of planets orbiting their stars' 'habitable zones.'
- Scientists found hammerhead sharks have twin cousin
The newly found scalloped hammerhead shark faces similar existential threats as its look-alike fishy cousin.
- Hammerhead shark twin discovery creates concern for species
The scalloped hammerhead shark has a twin, scientists have discovered. And that discovery may show that scalloped hammerheads are rarer than first thought.
