How Could A Sugar Pill Placebo Cause Harm?

A new review of data from 250,726 trial participants has found that 1 in 20 people who took placebos in trials dropped out because of serious adverse events. Almost half of the participants reported less severe adverse events. The adverse events ranged from abdominal pain and anorexia to burning, chest pain, fatigue, and even death.

Study: Breast Cancer Protection From Pregnancy Women

In general, women who have had children have a lower risk of breast cancer compared to women who have never given birth. However, new research has found that moms don't experience this breast cancer protection until many years later and may face an elevated risk for more than 20 years after their last pregnancy.

Spaceflight Does Not Compromise Major Part Of The Immune System Shows Research

With a new crew arriving at the International Space Station, astronauts will be relieved to know that they will not have to worry about a major aspect of their immune system being compromised. While scientists know about the astronauts' skeletal and muscular health during spaceflight and when they return to Earth, much less is known about how spaceflight affects immunity. It has been generally thought, until now, that spaceflight has a detrimental impact on all aspects of the immune system.

Researchers Create Noninvasive Technology That Detects When Nerve Cells Fire

Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells are based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level.The work was funded by the National Eye Institute, part of the National Institutes of Health.

Blood Test Helps Identify Distinct Molecular Signatures In Children With Cystic Fibrosis

Researchers at Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago, and colleagues, used a blood test and microarray technology to identify distinct molecular signatures in children with cystic fibrosis. These patterns of gene expression could help predict disease severity and treatment response, and lead to therapies tailored to each patient's precise biology. Findings were published in  Physiological Genomics.

The Importins Of Anxiety

According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. In a study described today in  Cell Reports , researchers at the Weizmann Institute of Science have revealed a previously unknown mechanism underlying anxiety. Targeting this biochemical pathway may help develop new therapies for alleviating the symptoms of anxiety disorders.
