According to the poll, women most admire the arms of first lady Michelle Obama, followed closely by Jennifer Aniston. Actresses Jessica Biel and Demi Moore, and daytime TV talk show host Kelly Ripa also got votes for their toned arms.

"I think we are always affected by the people that we see consistently, either on the big screen or on TV," said ASPS Public Education Committee Chair David Reath, MD, based in Knoxville, Tenn. "We see them and think, 'yeah, I'd like to look like that'."

Injection of human stem cells into mice with tumors slowed down tumor growth, finds research published in BioMed Central's open access journal Stem Cell Research & Therapy. Human mesenchymal stem cells (MSC), isolated from bone marrow, caused changes in blood vessels supplying the tumor, and it is this modification of blood supply which seems to impact tumor growth.

Being pregnant while young is known to protect a women against breast cancer. But why? Research in BioMed Central's open access journal Breast Cancer Research finds that Wnt/Notch signalling ratio is decreased in the breast tissue of mice which have given birth, compared to virgin mice of the same age.

High-risk women may derive the most benefit, least harms from preventive drug therapy.

Women at high risk for breast cancer may benefit most from preventive drug therapy. In 2002, the United States Preventive Services Task Force (USPSTF) recommended against routine use of tamoxifen and raloxifene for prevention of primary breast cancer for women at average risk.

April 28, 2013, Shenzhen, China- The Joint International Turtle Genomes Consortium, led by investigators from RIKEN, BGI, and Wellcome Trust Sanger Institute, has completed the genome sequencing of soft-shell turtle (Pelodiscus sinensis) and green sea turtle (Chelonia mydas). These achievements shed new light on the origin of turtles and applied the classical evo-devo model to explain the developmental process of their unique body plan. The findings were published online in Nature Genetics.

For the first time, researchers at Karolinska Institutet in Sweden have managed to obtain detailed images of the way in which the transport protein GLUT transports sugars into cells. Since tumours are highly dependent on the transportation of nutrients in order to be able to grow rapidly, the researchers are hoping that the study published in the scientific magazine Nature Structural & Molecular Biology will form the basis for new strategies to fight cancer cells.

Scientists from ETH Zurich have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides important new insights into the origin of brown fat cells, which is a prerequisite for the development of successful anti-obesity therapies.

The family Closteroviridae includes viruses causing economic losses in different agricultural crops worldwide, including citrus, grapevine and vegetables.

Presently, control of viral diseases consists of prophylactic measures to limit virus dispersion and the use of resistant cultivars obtained by plant breeding or genetic engineering. However, viruses have a great potential for rapid evolution and they often overcome the disease control methods.

Chloroplasts are complex green organelles that host the photosynthetic reactions within plant cells, converting solar into electric energy. They contain so-called plastoglobules, droplets of oil approximately 100 nm across.

Traditionally, plastoglobules have been viewed as "junk cupboards" for storing excess lipids. But in a new review article on this topic, Claire Bréhélin and colleagues from the University of Bordeaux synthetize data from recent proteomics studies on plastoglobules.

Ever since the origin of life on Earth, bacteria and Archaea have been far richer in species than any other group of organisms. But it is difficult to assess their full biodiversity because most species of bacteria and Archaea cannot be grown in the laboratory. For example, Persephonella bacteria – aptly named after the Greek goddess of hell, after their extreme habitat – can only survive around thermal vents on the ocean floor at depths of 2 to 3 km, under extreme pressure, in complete darkness, and in superheated water of up to 300 °C.

A unique app which allows you to peel back the layers of a masterpiece and uncover a previously hidden world has been developed by experts from Newcastle and Northumbria universities.

The 'Repentir' smart phone and iPad app has been designed to enhance the gallery experience, allowing visitors the opportunity to not just view the painting but also interact with it and explore the artist's creative process.

A collaborative team of physician-scientists at the Medical College of Wisconsin (MCW) and Children's Hospital of Wisconsin Research Institute has developed a new evidence-based, clinical algorithm to help physicians treat complex patients with autosomal recessive polycystic kidney disease (ARPKD).

A novel drug developed by Gilead Sciences and tested in an animal model at the Texas Biomedical Research Institute in San Antonio suppresses hepatitis B virus infection by stimulating the immune system and inducing loss of infected cells.

WASHINGTON (April 26, 2013) – New research out of the George Washington University Cancer Institute (GWCI) focuses on the difficulties of transitioning to adulthood while dealing with the long-term and late effects of cancer and its treatment. The study was recently published in the Journal of Oncology Navigation and Survivorship, titled "Improving Cancer Survivorship for Adolescents and Adults."

BUFFALO, N.Y. –A potential new treatment strategy for patients with Charcot-Marie-Tooth disease is on the horizon, thanks to research by neuroscientists now at the University at Buffalo's Hunter James Kelly Research Institute and their colleagues in Italy and England.
