Nisin: A Food preservative kills cancer cells

Scientists from University of Michigan report that Nisin, a naturally occurring food preservative that grows on dairy products, delivers a one-two punch to two of medicine's most lethal maladies: cancer and deadly, antibiotic-resistant bacteria.

Dinosaur love nests unearthed by Colorado research group

Dinosaurs engaged in mating behavior similar to modern birds, leaving fossil evidence behind in 100-million year old rocks, according to new research. Paleontologist Martin Lockley of the University of Colorado Denver led a research team that discovered what he called large “scrapes” in prehistoric Dakota sandstone in western Colorado.

Real life King-Kong may have been doomed by changing landscape—and own size

An ape thought to be the largest in Earth’s history died out because it couldn’t adapt or get enough food in a changing landscape about 100,000 years ago, scientists argue in a new study. The giant ape Gigantopithecus weighed an estimated 200 to 500 kg, or 400 to 1,111 pounds. That’s up to three times heavier than the largest living species of gorilla, the Eastern lowland gorilla.

Scientists found DNA-like molecule that assemble itself

Chemists say they have found a way to make a DNA-like molecule assemble itself in a pond-like setting—potentially suggesting a key step in how life originated. The researchers actually worked with a simpler molecule, called pre-RNA. It’s hypothesized to have eventually evolved into DNA—one stopping point along the way having been the creation of a third substance, RNA, still used in the body to translate the code inscribed in DNA.

Chitchat and small talk could serve an evolutionary need to bond with others

We think of chitchat and small talk as the things people say to pass the time or kill an awkward silence. But new research suggests these idle conversations could be a social-bonding tool passed down from our ape-like ancestors.

Parrots seen using pebble as grinding tool

Captive parrots of a species known as Greater Vasa have been documented for the first time using tools—and doing so in ways never reported among other animals, scientists say. The birds used small pebbles or date pits to grind calcium powder from seashells, or to break off bits of shell to swallow, according to the new findings. That’s the first evidence of a nonhuman using tools for grinding, said the scientists.

Male and female brains are structurally same : new study

Although male and female brains tend to be different, no single structural feature clearly distinguishes them, scientists have concluded in a new study. The way it seems to work, they say, is like this: “most brains are comprised of unique ‘mosaics’ of features, some more common in females compared with males, some more common in males compared with females, and some common in both females and males.”

LSD reorganize human brain networks and changes consciousness

The drug LSD creates its bizarre effects on the brain in part by stopping some nerve cells from acting synchronously, as they should—while making others act in concert where they shouldn’t. That’s the conclusion of a group of researchers presenting new findings Dec. 10 at the annual meeting of the American College of Neuropsychopharmacology in Hollywood, Florida.

New research : Happiness and unhappiness have no direct effect on mortality

A study of a million U.K. women has found that contrary to widespread belief, happiness or lack of it have no direct effect on mortality. “Illness makes you unhappy—but unhappiness itself doesn’t make you ill,” said the study’s lead author, Bette Liu, summing up the findings.
