Data on Carbohydrates are Incorrect

April 20, 2015 3:00 pm | by Univ. of York | Comments

Carbohydrates, commonly known as sugars, are complex biological molecules linked to many fundamental cellular processes in living organisms. But, scientists have identified problems with nearly half of the structural data on carbohydrate molecules available to the scientific community.

Study Sheds Light on Where Diamonds Reside

April 20, 2015 3:00 pm | by The Univ. of Western Australia | Comments

A team of specialists has established the exact source of a diamond-bearing rock for the first time. These rocks, orangeites, are already commonly found in South Africa. However, the new study now reveals that they may be present in much higher abundance worldwide.

Chatty Fat May Raise Blood Pressure

April 20, 2015 3:00 pm | by Michigan State Univ. | Comments

For years, belly fat has been linked to high blood pressure, or hypertension, which increases a person’s risk for cardiovascular disease. But scientists haven’t known exactly why. Now, researchers are suggesting that high blood pressure could be caused by belly fat hormones “talking” with blood vessels in the abdomen.

Oldest Fossil is Key to Solving Controversy

April 20, 2015 3:00 pm | by The Univ. of Western Australia | Comments

New analysis of world-famous 3.46-billion-year-old rocks by researchers is set to finally resolve a long-running evolutionary controversy. The new research shows that structures once thought to be Earth's oldest microfossils do not compare with younger fossil candidates but have, instead, the character of peculiarly shaped minerals.

Three Diseases All Linked

April 20, 2015 7:00 am | by Univ. of Colorado Denver | Comments

New research shows the link between cancer, diabetes and cardiovascular disease. Obesity has adverse effects on the heart and can contribute to the development of cancer. But researchers tend to study these things in isolation, by disease and not by risk factor. Shared risk factors for cancer, diabetes and cardiovascular disease also include, tobacco, diet quality, physical activity and alcohol use.

Astronomers Solve Cold Cosmic Mystery

April 20, 2015 7:00 am | by Univ. of Hawaii at Manoa | Comments

In 2004, astronomers examining a map of the radiation leftover from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected. Now, a team may have found an explanation for its existence.
