In ancient times, these powerful carnivores inhabited the frigid Arctic during the last ice age, according to a new study led by the University at Buffalo.
Coming mostly from tap and especially bottled water, nearly invisible bits of polymer were also found in shellfish, beer and salt, a report by scientists and the University of Newcastle in Australia found.
An exoplanet smaller than Neptune with its own atmosphere has been discovered in the Neptunian Desert, by an international collaboration of astronomers.
A University of Bristol academic may have succeeded where countless cryptographers, linguistics scholars and computer programs have failed — by cracking the code of the "world's most mysterious text," the Voynich manuscript.
With its Chang'e 4 mission, China hopes to be the first country to ever successfully undertake such a landing.
A new study by a pair of astronomers from the Harvard Smithsonian Center for Astrophysics (CfA) has suggested that 'Oumuamua may actually be a light sail of extra-terrestrial origin.
What happens when a new technology is so precise that it operates on a scale beyond our characterization capabilities?
Analysis revealed that interest in sex peaks significantly during major cultural or religious celebrations.
Antibiotics normally act in concert with an organism's immune system to eliminate an infection, but the drugs can also have broad side effects.
A team of researchers from the UK and the US has mapped the biggest dinosaur tree yet, and in so doing, has found that the creatures may have evolved 20 million years earlier than most in the field have thought.
The 58-story Millenium Tower has gained notoriety in recent weeks as the "leaning tower of San Francisco." But it's not just leaning. It's sinking, too. And engineers hired to assess the problem say it shows no immediate sign of stopping.
Many home chefs consider pancake cooking to be an art, but really, it's a science.
El Niño has swept into the Golden State and is breathing life back into the area. To many, it might seem that this storm front could end the drought and set California back on track. And it is making a difference, but like all things climate-related, it's complicated and hard to predict.
Researchers have designed a new type of microgear that spins when micromotors become lodged into the corners of the gear's teeth. The micromotors use the surrounding hydrogen peroxide solution as fuel to propel themselves forward, which in turn causes the microgears to spin. In the future, the tiny gears could be used as the building blocks for making autonomous micromachines.
Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon.
Nothing wrecks a beautiful night sky like that hideous pockmarked spotlight. What would it take to destroy it and eliminate the enemy of stellar astronomy for all time?
The world population, which stood at 5 billion in 1950, is predicted to increase to 10.5 billion by 2050. It's a stunning number since it means the planet's population has doubled within the lifetimes of many people alive today. At the same time, arable land is shrinking and crop productivity is stagnating.
Because Earth is the only place that we know has life, uncovering its origins is a considerable challenge. That said, scientists have not ruled out the other locations in the Solar System. There are several icy moons that could have oceans with microbial life inside, such as Europa (at Jupiter) or Enceladus (at Saturn). And much closer to us is an entire planet with a history of water — Mars.
Scientists working in the desert badlands of northwestern Kenya have found stone tools dating back 3.3 million years, long before the advent of modern humans, and by far the oldest such artifacts yet discovered.
For the first time, IBM engineers successfully implemented error-correction, a crucial element to a working quantum computer.
