Environment affects immunity more than genetics

A new study into twins reveals that environmental factors play a greater role in shaping individual immunity than genetic ones.

A new study has found that cells possess finger-like projections that are used to sense the external environment. These projections can detect the chemical environment and they can "feel" the through ultrasensitive sensors.

Mom was right, it is best to wrap up warm in the winter

Wrap up warm or you’ll catch a cold is a common saying. There may be an element of truth to this for the cold causing virus is more virulent in cold temperatures when compared with warmer ones.

No bird brains, crows are super-smart

Experiments initiated by the University of Iowa have found that crows can show advanced relational thinking. This puts them on par with apes and monkeys.

Solving the cellular conundrum, seeing how cells grow

Cell division has been part and parcel of our understanding of science for over a century. However, what exactly causes cells to divide? This is still a conundrum for scientists.

H7N9 strain mutated from chicken flu virus

Scientists have demonstrated how changes in a flu virus common to Chinese poultry farms triggered the rise of the novel avian H7N9 influenza A virus that has sickened hundreds of people since 2013.

Oldest Gospel fragment discovered in mummy mask

Possibly the earliest known fragment of the New Testament, a papyrus with words from the Gospel of Saint Mark, has been discovered in a lower-class Egyptian mummy’s burial mask, dating from the First century, about 80-90 A.D.

Scientists grow human intestines inside a mouse

Scientists have begun growing human intestines in mice. The object of the research is to pave the way for better models of intestinal function and failure.

Pitcher plants switch traps on and off, by the weather

New research shows how carnivorous pitcher plants gobble more ants by turning off their traps as the temperature rises and the weather becomes drier.

Call for transparency with clinical trial data

The U.S. Institute of Medicine says results from human clinical trials ought to be made available to independent researchers within 18 months. This makes new drugs and their potential side-effects easier to evaluate.

'Sea monster' pulled from waters off Australia — frilled shark

The creature looks like the stuff of nightmares, a living fossil rising out of the sea, its mouth a chewing machine of 300 teeth set in 25 rows. It is the rarely seen frilled shark.

Op-Ed: DNA manipulation — Designing perfect babies

Advancements in genetic modification and DNA editing make the possibility of creating customized designer babies a reality. Is this medical advancement really a good idea?

Studies show dogs were domesticated before cattle

At one time or another, we have all pondered the question of which came first, the chicken or the egg? But have you ever wondered which animal, the cow or the dog, was domesticated first? You may be surprised by the answer.

Big cache of weapons seized by Gen. Sherman may have been found

Civil War General William. Tecumseh Sherman's name still draws boos and hisses in South Carolina, after destroying the capital on his way out of town 150 years ago. Now, Sherman is creating another ruckus. His loot has been found at the bottom of a river.

Taking life to Mars: Team to grow plants on Red Planet

The Seed Team, a group of young researchers, has won a competition on the best experiments to conduct on Mars, and will be sending seeds to the Red Planet, to grow plants there.

'Man's best friend' arrived late to the Americas

New research suggests that dogs may have arrived in the Americas around 10,000 years ago, thousands of years after the first humans arrived.

Skeleton from Greek mystery tomb to be identified next month

Bones from at least five people, including a baby and an elderly woman, were identified in a massive tomb in Greece dating back to the era of Alexander the Great, the culture ministry said Monday.

NASA: Huge asteroid 2004 BL86 will narrowly miss Earth, Jan. 26

A massive asteroid, about a third of a mile in diameter, will pass close to Earth on Jan. 26. NASA says asteroid 2004 BL86 will pass safely, making closest approach at about three times the distance of Earth to the moon at 16:20 UTC, or 11:20 a.m. EST.

Sea turtles use Earth's magnetic field to navigate home: study

For millions of years, sea turtles have navigated the oceans to return to their birthplace to excavate nests and lay eggs. Scientists have long been mystified because it wasn't known how they did this.

Two unknown Earth-sized planets may be part of Solar System

Scientists tracking the orbits of objects on the extreme edge of our solar system believe that there is a good chance that two planets, at least as large as Earth may exist out there.

New 'ghost particle' may prove aliens exist, say researchers

An oddly shaped microscopic structure has been found in the outer reaches of the Earth's atmosphere, say scientists from Sheffield University, who claim that this could be proof of alien life!

Ireland's long history with dairy farming revealed

Dairy farmers across Europe are anxiously awaiting the phase out and eventual end of E.U. milk quotas in April of this year. With milk being a valuable and traditional commodity today, researchers looked back at dairying in Ireland 6,000 years ago.

A new guinea pig model of Ebola viral transmission, from Canadian scientists, shows that direct contact with infected animals is not necessary to catch the disease. The results could inform about health protection.

Obesity due to genes, environment and time

New research indicates that a common genetic variant increases the risk of obesity only in people born after 1942. This means genes, environment and time are key factors.

Fat can help fight infections

A new study shows that adipocytes under the skin can help fight infections by producing an antimicrobial agent. A note of caution, though, being overweight does not grant greater immunity.
