Is our universe unique? From science fiction to science fact, there is a proposal out there that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. So, instead of turning down that job offer that took you from the United States to China, the alternate universe would show the outcome if you decided to venture to Asia instead.
An odd, tailless comet that made a fleeting pass into the inner solar system in 2014 before heading back out to the distant Oort cloud actually may have been visiting close to its birthplace.
The comet, called C/2014 S3, is physically more like an inner belt, rocky asteroid than an icy comet forged in the solar system’s deep freeze, a new study shows.
A new study of eight years of radar data collected by the Saturn-orbiting Cassini spacecraft shows that the planet’s largest moon, Titan — the only other body in the solar system besides Earth where liquids pool on the surface — has a sea of pure methane.
Astronomers revised the half-century old Drake equation, which attempts to calculate the probability of the existence of advanced alien civilizations, to determine whether such civilizations has existed at any point in the history of the universe.
It’s an oft-reported, can-you-even-believe-it fact that many people in Iceland still believe in the possible existence of elves. This myth from the country’s folk traditions has persisted, and the niggling suspicion that the Good Folk may still be out there among the rocks has even led to Icelandic road and housing plans being altered to avoid sites associated with them. Now, there’s an incredibly detailed map that shows you exactly where such sites can be found.

The record-setting burn is meant to send a message to the world that ivory has no value and that its trade should be banned.
As widely reported here, Africa is in the midst of a poaching crisis, driven primarily by demand in Asia for wildlife products. Three-quarters of illegal ivory makes its way to China, while Vietnam is the largest market for rhino horn.
Mathematically speaking, the way a tiger charges a herd of antelope resembles a white blood cell attacking a colony of bacteria. That’s the conclusion of a new paper by an international team of physicists, just published in Journal of Physics A: Mathematical and Theoretical.
Horses snooze in their stalls. Fish take their 40 winks floating in place. Dogs can doze anywhere, anytime. And even the lowly worm nods off now and then.
All animals, most scientists agree, engage in some form of sleep.
Apologies to people keen on reviving extinct dinosaurs, but researchers have never recovered dinosaur DNA, which is necessary for cloning. But, intriguingly, they have found fragments of mystery DNA in dinosaur bone, experts told Live Science.
The Burning Tree mastodon, discovered in 1989 on a Licking County golf course, is known internationally for being the most complete American mastodon skeleton ever found.
The mastodon also had spear marks in its ribs, proving a theory about how Paleo-Indian tribes that hunted across Ohio and the rest of North America fed themselves.
Blombos Cave in South Africa has given us vast knowledge about our early ancestors, realigning scientific notions of the origins of early modern behavior, pushing back the dates of evidence of sophisticated cognitive actions such as flint working, ritual behaviors and personal decoration some 50,000 years earlier than the cave paintings of Upper Paleolithic Europe.
A new study has provided fresh insights into Mound Key, an artificial island constructed by the Calusa people.
The interdisciplinary project, led by University of Georgia anthropologist Victor Thompson, has looked at how the composition of the island changed over the centuries, particularly in relation to environmental and social shifts. The team’s results were published this week in the open access journal, PLOS ONE.
A new genetic study of male ancestry shows there were periods in human prehistory when just a few elite men controlled reproduction.
For example, one man about 190,000 years ago was the ancestor of 1,200 living men from 26 groups around the world whose genes were analyzed for the new study.
Roman rule meant the control of Rome on ports and marine and land trade routes. In fact, Roman maritime commercial traffic was so important that they improved and expanded existing land routes, creating a vast road network in many regions, which was in service until the 18th century. This allowed them to develop and consolidate areas of commercial influence on some ports – transforming them into centers for very important economic activity.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) recently visited the ancient Syrian city of Palmyra to assess the damage and destruction done to it when it fell under the control of the Islamic State terrorist group (ISIS).
Though the city, a world heritage site, has been considerably damaged, it still continues to retain its integrity and authenticity, affirmed UNESCO.
