A team of bioengineers at Brigham and Women's Hospital (BWH), led by Ali Khademhosseini, PhD, and Nasim Annabi, PhD, of the Biomedical Engineering Division, has developed a new protein-based gel that, when exposed to light, mimics many of the properties of elastic tissue, such as skin and blood vessels. In a paper published in Advanced Functional Materials, the research team reports on the new material's key properties, many of which can be finely tuned, and on the results of using the material in preclinical models of wound healing.

Without carbon dioxide, life as we know it on earth would end in sudden, spectacular fashion - but too much of anything can be a bad thing, and that goes for vegan food or a key component in photosynthesis like CO2.
Lawyers at the Center for Biological Diversity and oceanographer Dr. Donn Viviani have petitioned the Obama administration to regulate carbon dioxide under the federal Toxic Substances Control Act.

To mark the final day of the 65th Lindau Nobel Laureate Meeting, on Friday, 3 July, over 30 Nobel laureates assembled on Mainau Island on Lake Constance signed a declaration on climate change. The "Mainau Declaration 2015 on Climate Change" states "that the nations of the world must take the opportunity at the United Nations Climate Change Conference in Paris in December 2015 to take decisive action to limit future global emissions." It is expected that a new international agreement on climate protection will be approved at the 21st UN Climate Conference to succeed the Kyoto Protocol.

For the first time gene therapy for cystic fibrosis has shown a significant benefit in lung function compared with placebo, in a phase 2 randomized trial. The technique replaces the defective gene response for cystic fibrosis by using inhaled molecules of DNA to deliver a normal working copy of the gene to lung cells.

There may be far fewer galaxies further out in the Universe then might be expected, suggests a new study based on simulations conducted using the Blue Waters supercomputer at the National Center for Supercomputing Applications, with resulting data transferred to SDSC Cloud at the San Diego Supercomputer Center at the University of California, San Diego, for future analysis.

A new study that is the first to use Social Security Administration's personal income tax data tracking the same individuals over 20 years to measure individual lifetime earnings has confirmed significant long-term economic benefits of college education.
ChangHwan Kim, a University of Kansas researcher, said the research team was also able to account for shortcomings in previous studies by including factors such as gender, race, ethnicity, place of birth and high school performance that would influence a person's lifetime earnings and the probability of college completion.

Researchers have discovered that a human antibody specific to dengue virus serotype 2, called 2D22, protects mice from a lethal form of the virus -- and they suggest that the site where 2D22 binds to the virus could represent a potential vaccine target.
The mosquito-borne virus, which infects nearly 400 million people around the world each year, has four distinct serotypes, or variations, and there is currently no protective vaccine available.

A new method for calculating the exact time of death, even after as much as 10 days, has been developed by a group of researchers at the University of Salzburg.
Currently, there are no reliable ways to determine the time since death after approximately 36 hours. Initial results suggest that this method can be applied in forensics to estimate the time elapsed since death in humans.
