Humanity is on the constant search for improvements in cancer treatments, and the International Space Station has provided a microgravity platform that has enabled advancements in the cancer treatment process.

Higher risk of birth defects from assisted reproduction, study suggests

Posted: 05 May 2012 10:09 AM PDT

A new study has identified the risk of major birth defects associated with different types of assisted reproductive technology. In the most comprehensive study of its kind in the world, researchers compared the risk of major birth defects for each of the reproductive therapies commonly available internationally, such as: IVF (in vitro fertilization), ICSI (intracytoplasmic sperm injection) and ovulation induction. They also compared the risk of birth defects after fresh and frozen embryo transfer.

A single stem cell mutation triggers fibroid tumors: Mutated stem cell 'goes wild' in frenzied tumor expansion

Posted: 04 May 2012 02:21 PM PDT

Fibroid uterine tumors affect an estimated 15 million women in the United States, causing irregular bleeding, anemia, pain and infertility. Despite the high prevalence of the tumors, the molecular cause has been unknown. Scientists for the first time have identified the molecular trigger of the tumor -- a single stem cell that develops a mutation, starts to grow uncontrollably and activates other cells to join its frenzied expansion.

Means to detect low-level exposure to seafood toxin in marine animals developed

Posted: 04 May 2012 11:30 AM PDT

Scientists have discovered a biological marker in the blood of laboratory zebrafish and marine mammals that shows when they have been repeatedly exposed to low levels of domoic acid, which is potentially toxic at high levels.

Hip implant for long-term use

Posted: 04 May 2012 10:58 AM PDT

Hip replacement is one of the most frequent operations carried out in Germany. Each year, doctors implant some 200,000 artificial hip joints. Often the artificial hips need to be replaced just ten years later. In the future, a new implant currently being developed using high technology materials could help prevent premature revision surgeries.

Clean animals result in fewer E. coli

Posted: 04 May 2012 08:00 AM PDT

Following the E. coli case in Norway in 2006, when 17 people fell ill and one child died after eating mutton sausages, the meat industry introduced a number of measures in order to reduce the risk of food poisoning from meat. Clean animals and good hygiene during slaughtering are essential preconditions for food safety.

Synesthesia may explain healers claims of seeing people's 'aura'

Posted: 04 May 2012 08:00 AM PDT

University of Granada researchers affirm that healers present synesthesia, a neuropsychological phenomenon involving a "mingling" of the senses. The results of this study have been published in the prestigious journal Consciousness and Cognition. The authors remark the significant "placebo effect" that healers have on ill people.

Sloppy shipping of human retina leads researchers to discover new treatment path for eye disease

Posted: 04 May 2012 07:58 AM PDT

Sloppy shipping of a donated human retina to a researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.
