Study: One-fifth of spine surgery patients develop PTSD symptoms

PORTLAND, Ore. – Nearly 20 percent of people who underwent low back fusion surgery developed post-traumatic stress disorder symptoms associated with that surgery, according to a recent Oregon Health & Science University study published in the journal Spine.

Past studies have noted PTSD symptoms in some trauma, cancer and organ transplant patients. But this is the first study, its authors believe, to monitor for PTSD symptoms in patients undergoing an elective medical procedure.

Stanford bioengineers introduce 'Bi-Fi' -- The biological internet

STANFORD, Calif. — If you were a bacterium, the virus M13 might seem innocuous enough. It insinuates more than it invades, setting up shop like a freeloading houseguest, not a killer. Once inside it makes itself at home, eating your food, texting indiscriminately. Recently, however, bioengineers at Stanford University have given M13 a bit of a makeover.

Identification of microbes in healthy lungs sheds light on cystic fibrosis

STANFORD, Calif. — Healthy people's lungs are home to a diverse community of microbes that differs markedly from the bacteria found in the lungs of cystic fibrosis patients. That's the result of new research from Stanford University and Lucile Packard Children's Hospital, which has wide implications for treatment of cystic fibrosis and other lung diseases.

Predatory bacterial crowdsourcing

HOUSTON -- (Sept. 27, 2012) -- Move forward. High-five your neighbor. Turn around. Repeat.

That's the winning formula of one of the world's smallest predators, the soil bacteria Myxococcus xanthus, and a new study by scientists at Rice University and the University of Texas Health Science Center at Houston (UTHealth) Medical School shows how Myxococcus xanthus uses the formula to spread, engulf and devour other bacteria.

Bioengineers at UCSB design rapid diagnostic tests inspired by nature

(Santa Barbara, Calif.) –– By mimicking nature's own sensing mechanisms, bioengineers at UC Santa Barbara and University of Rome Tor Vergata have designed inexpensive medical diagnostic tests that take only a few minutes to perform. Their findings may aid efforts to build point-of-care devices for quick medical diagnosis of sexually transmitted diseases (STDs), allergies, autoimmune diseases, and a number of other diseases. The new technology could dramatically impact world health, according to the research team.

Big science: Local funding supports open-access sequencing of the Puerto Rican Parrot genome

The critically endangered Puerto Rican Parrot (Amazona vittata) is the only surviving parrot species native to the United States. A genomic sequencing project, funded by community donations, has published today, in BioMed Central and BGI's open access journal GigaScience, the first sequence of A. vittata, the first of the large Neotropical Amazona birds to be studied at the genomic level.

Ancient stinging nettles reveal Bronze Age trade connections

A piece of nettle cloth retrieved from Denmark's richest known Bronze Age burial mound Lusehøj may actually derive from Austria, new findings suggest. The cloth thus tells a surprising story about long-distance Bronze Age trade connections around 800 BC. The findings have just been published in Nature's online journal Scientific Reports.

2,800 years ago, one of Denmark's richest and most powerful men died. His body was burned. And the bereaved wrapped his bones in a cloth made from stinging nettle and put them in a stately bronze container, which also functioned as urn.

Learning to live on Mars

Boston, MA—Since the beginning of August, NASA's Mars rover, Curiosity, has been roaming all over the distant planet learning as much as it can about the Martian terrain. The mission control team back on Earth has also learned what it may be like on Mars by trying to live and work on a Martian day, which is about 40 minutes longer than an Earth day. This 'day' length causes havoc with the internal 24-hour body clock but researchers at Brigham and Women's Hospital (BWH) have developed and tested a fatigue management program which is successful at controlling this space-age jetlag.

The true costs of cancer in Europe revealed

Vienna, Austria, 28 September 2012 – New studies that reveal for the first time the real economic and human costs of caring for cancer patients in Europe will be presented during the ESMO 2012 Congress of the European Society for Medical Oncology in Vienna.

Local funding leads to big things in parrot genomics

September 28, 2012, Hong Kong, China – The international open-access journal GigaScience (a BGI and BioMed Central journal) announces the publication of a unique study providing the genome sequence of the critically endangered Puerto Rican Parrot (Amazona vittata) by Taras Oleksyk and colleagues at the University of Puerto Rico-Mayaguez. The sequencing and analysis of the genome of the only surviving native parrot in US territory provides numerous benefits for avian genetics, conservation studies, and evolutionary analyses.

Honey bees fight back against Varroa

The parasitic mite Varroa destructor is a major contributor to the recent mysterious death of honey bee (Apis mellifera) colonies. New research published in BioMed Central's open access journal Genome Biology finds that specific proteins, released by damaged larvae and in the antennae of adult honey bees, can drive hygienic behavior of the adults and promote the removal of infected larvae from the hive.
