Earliest Humans May Have Gripped Like Us

April 21, 2015 7:00 am | by Yale Univ. | Comments

Scientists are coming to grips with the superior grasping ability of humans and other primates throughout history. In a new study, a research team found that even the oldest known human ancestors may have had precision grip capabilities comparable to modern humans.

Image of the Week: Imaging Immune System Helps Fight Cancer

April 21, 2015 7:00 am | by Whitehead Institute for Biomedical Research | Comments

A novel approach that allows real-time imaging of the immune system’s response to the presence of tumors— without the need for blood draws or invasive biopsies— offers a potential breakthrough both in diagnostics and in the ability to monitor efficacy of cancer therapies.

Roadmap Could Aid Breading of Better Cotton

April 21, 2015 7:00 am | by The Univ. of Texas at Austin | Comments

A team has developed the most precise sequence map yet of U.S. cotton and will soon create an even more detailed map for navigating the complex cotton genome. The finding may help lead to an inexpensive version of American cotton that rivals the quality of luxurious Egyptian cotton and helps develop crops that use less water and fewer pesticides for a cotton that is easier on the skin and easier on the land.

It's Sad You've Never Heard of Patrick Matthew

April 21, 2015 7:00 am | by King’s College London | Comments

The horticulturist who came up with the concept of evolution by natural selection 27 years before Charles Darwin did should be more widely acknowledged for his contribution, a new paper argues. Patrick Matthew deserves to be considered alongside Charles Darwin and Alfred Russel Wallace as one of the three originators of the idea of large-scale evolution by natural selection.

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.

Five Years After Disaster, Drillers Push to Go Deeper

April 20, 2015 3:00 pm | by Associated Press, Cain Burdeau | Comments

The Deepwater Horizon oil rig exploded on April 20, 2010. Five years after the nation's worst offshore oil spill, the industry is working on drilling even further into the risky depths beneath the Gulf of Mexico to tap massive deposits once thought unreachable.

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.

What Time Is It? Yellow O'clock

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

Research has revealed that the color of light has a major impact on how our body clock measures the time of day. It’s the first time the impact of color has been tested and demonstrates that color provides a more reliable way of telling the time than measuring brightness.

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.

Today in Lab History: The Curies Isolate Radium

April 20, 2015 7:00 am | by Lily Barback, Associate Editor | Comments

Marie and Pierre Curie isolated one-tenth of a gram of radioactive radium from several tons of pitchblende ore on April 20, 1902. In 1903, the couple shared the Nobel Prize in physics with French scientist A. Becquerel for their groundbreaking investigations of radioactivity.

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.
