Don't Blame The Sun For Climate Change: Solar Activity Has Little Effect on Earth's Temperature, Study Says
Dec 23, 2013 14:02 PM E
Solar activity has little effect on global climate change, according to a new University of Edinburgh study. The researchers compared 1,000 years of tree rings and historical records to determine whether fluctuations in solar activity corresponded to climate change. They found that the sun has little effect, and that the primary causes of climate change were volcanic activity and greenhouse gasses.

Wari Healers In Peru Experimented With Brain Surgery Over 1,000 Years Ago
Dec 23, 2013 11:53 AM E
The Wari civilization in Peru experimented with trepanning, according to the research from the University of California. Thirty-two Wari individuals showed 45 instances of the brain surgery. The study, "Trepanation in South-Central Peru during the early late intermediate period (ca. AD 1000–1250)," was led by Danielle Kurin.

Reindeer Eyes Change Color To Adapt To Arctic Seasons' Crazy Light Changes
Dec 21, 2013 12:15 PM E
Reindeers' eye color shifts as a result of light changes in Arctic seasons. The tapetum lucidum, which sits behind the retina, changes to blue in winter months when reindeers' pupils dilate for months on end. It is the first time a mammals' tapetum lucidum has been shown to change color.

Extinct Moa Birds Of New Zealand Were Not As Robust As Previously Thought
Dec 18, 2013 17:49 PM E
The extinct moa bird of New Zealand was not as robust as previously believed, new research suggests. The University of Manchester study digitally reconstructed several moa species and found that their body mass was large, but not as large as past estimates.

Chimpanzees Learn Food Preparation From One Another, Study Suggests
Dec 18, 2013 15:24 PM E
Chimpanzees learn from one another how to open fruit, a new study suggests. Bruce Rawlings and Marina Davila-Ross from the University of Portsmouth, in England, looked at three different chimp groups and found that different methods of opening the fruit emerged in each group, indicating that the members of each group were learning from one another.

Diamonds In Antarctica: Researchers Discover Kimberlite Deposits, Which May Contain Precious Stones
Dec 17, 2013 17:57 PM E
Researchers have found kimberlite in Antarctica, a rare rock that may contain diamonds. Greg Yaxley of the Australian National University in Canberra, who led the research on the kimberlite, said that it would be "very surprising" if the kimberlite didn't contain diamonds. While mining in Antarctica is illegal due to a 1991 protocol ...

Neanderthals Buried Their Dead In Caves, Researchers Find
Dec 17, 2013 14:50 PM E
Neanderthals buried their dead, a new study finds. Studying remains found at La Chapelle-aux-Saints cave in southwestern France, study author William Rendu found bones buried in pits that were not naturally formed. The study, "Evidence supporting an intentional Neanderthal burial at La Chapelle-aux-Saints," was published in Proceedings of the National Academy of Sciences.

1.4 Million-Year-Old Hand Fossil Discovered: Bone Gave Human Ancestors Ability To Make Tools
Dec 16, 2013 15:47 PM E
Researchers have found the earliest example of a bone which is key to the way the human hand functions. The a 1.4 million-year-old bone gives humans the ability to make and use tools, and millions of years ago it gave human ancestors the same ability. The bone, the third metacarpal, was discovered in West Turkana, Kenya.

Hubble Space Telescope Finds Evidence Of Water Plumes On Jupiter's Moon Europa
Dec 13, 2013 18:20 PM E
Evidence of water plumes have been detected on Jupiter's moon Europa by the Hubble Space Telescope. Hubble didn't see the plumes, but collected strong evidence that the plumes exist due to hydrogen and oxygen levels there. If there is water on Europa, then that of course opens the possibility of extraterrestrial life.

'Spermbot' Could Be Used To Fertilize Eggs, Deliver Targeted Medicine In Humans
Dec 13, 2013 15:28 PM E
A "spermbot" created by German scientists could one day be used to fertilize human eggs and to deliver medicine to targeted parts of the body. In a study using bull sperm, scientists were able to trap a sperm in a metal nanotube, which could then be guided to a desired location. A paper on the spermbot appears in the journal Advanced Materials.

The Comb Jelly Was Our First Ancestor, Surprising Evolution Study Says
Dec 12, 2013 17:07 PM E
The first animal was the comb jelly, according to a new study that displaces the sponge at the base of animal evolution. Sponges have long been thought to be the first animals. Comb jellies are more evolved than sponges, making it counterintuitive that they would have evolved from sponges--and calling into question much of what we know about evolution.
