Tumor suppressor gene TP53 mutated in 90 percent of most common childhood bone tumor

(MEMPHIS, Tenn. – April 3, 2014) – The St. Jude Children's Research Hospital—Washington University Pediatric Cancer Genome Project found mutations in the tumor suppressor gene TP53 in 90 percent of osteosarcomas, suggesting the alteration plays a key role early in development of the bone cancer. The research was published today online ahead of print in the journal Cell Reports.

Sanford-Burnham presents cancer research at AACR

LA JOLLA, Calif., April 3, 2014 — Sanford-Burnham Medical Research Institute will present a wide range of new research data at the annual American Association for Cancer Research Meeting in San Diego starting Saturday, April 5, at the San Diego Convention Center. The presentations will cover a variety of topics including breast, melanoma, and prostate cancer, as well as novel methods of delivering drugs to tumors.

A new approach to detecting changes in GM foods

Does genetic manipulation causes unintended changes in food quality and composition? Are genetically modified (GM) foods less nutritious than their non-GM counterparts, or different in unknown ways?

Despite extensive cultivation and testing of GM foods, those questions still linger in the minds of many consumers. A new study in the March issue of The Plant Genome demonstrates a potentially more powerful approach to answering them.

Sage grouse losing habitat to fire as endangered species decision looms

As fires sweep more frequently across the American Great Basin, the US Bureau of Land Management (BLM) has been tasked with reseeding the burned landscapes to stabilize soils. BLM's interventions have not helped to restore habitat for the greater sage grouse (Centrocercus urophasianus) reported scientists from the US Geological Survey (USGS) and US Forest Service in the Ecological Society of America's journal Ecosphere last week, but outlier project sites with good grouse habitat may yield clues to successful management scenarios.

Examination of a cave-dwelling fish finds a possible genetic link to human disorders

Researchers have identified a genetic association with facial asymmetry in an ancient cavefish, a natural trait that may solve mysteries surrounding facial asymmetries in humans – conditions such as cleft palate or hemifacial microsomia. This exciting discovery by Joshua Gross, a University of Cincinnati assistant professor for the Department of Biological Sciences; and doctoral students Amanda Krutzler and Brian Carlson, is published in the research journal, Genetics.

Indigenous societies' 'first contact' typically brings collapse, but rebounds are possible

It was disastrous when Europeans first arrived in what would become Brazil -- 95 percent of its population, the majority of its tribes, and essentially all of its urban and agricultural infrastructure vanished. The experiences of Brazil's indigenous societies mirror those of other indigenous peoples following "first contact."

A new study of Brazil's indigenous societies led by Santa Fe Institute researcher Marcus Hamilton paints a grim picture of their experiences, but also offers a glimmer of hope to those seeking ways to preserve indigenous societies.

Nanoparticles cause cancer cells to self-destruct

Using magnetically controlled nanoparticles to force tumour cells to 'self-destruct' sounds like science fiction, but could be a future part of cancer treatment, according to research from Lund University in Sweden.

Attracting wild bees to farms is a good insurance policy

EAST LANSING, Mich. -- Investing in habitat that attracts and supports wild bees in farms is not only an effective approach to helping enhance crop pollination, but it can also pay for itself in four years or less, according to Michigan State University research.

The paper, published in the current issue of the Journal of Applied Ecology, gives farmers of pollination-dependent crops tangible results to convert marginal acreage to fields of wildflowers, said Rufus Isaacs, MSU entomologist and co-author of the paper.

Synergy of high protein intake and exercise in youth enhances bone structure and strength

A study presented during the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases in Seville shows that high levels of protein intake (HProt) enhance the positive impact of high physical activity (HPA) on bone structure and strength in healthy pre-pubertal boys.

Report documents cardiopulmonary arrest in premature infant after cyclomydril eyedrops

San Francisco, CA, April 2, 2014 – Eyedrops administered to infants as part of routine outpatient retinopathy of prematurity (ROP) screening can have life-threatening consequences. A case report published in the current issue of the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) describes cardiopulmonary arrest in a 27-week-old infant following administration of three sets of cyclopentolate 0.2%/phenylephrine 1% (Cyclomydril) eyedrops.

Drawing conclusions

Is a picture worth only a thousand words? According to Dr. Carmit Katz of Tel Aviv University's Bob Shapell School of Social Work, illustrations by children can be a critical tool in forensic investigations of child abuse.

Structural insights into the inner workings of a viral nanomachine

Researchers at the Virginia Tech Carilion Research Institute (VTCRI) are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered particle (DLP). These DLPs are the form of the virus that produces messenger RNA molecules, which are critical for launching the infection.

An ultrathin collagen matrix biomaterial tool for 3D microtissue engineering

A novel ultrathin collagen matrix assembly allows for the unprecedented maintenance of liver cell morphology and function in a microscale "organ-on-a-chip" device that is one example of 3D microtissue engineering.

Immune cell defenders protect us from bacteria invasion

The patented work, published in Nature today, provides a deeper understanding of our first line of defence, and what happens when it goes wrong. It will lead to new ways of diagnosing and treating inflammatory bowel disease, peptic ulcers and even TB. It could also lead to novel protective vaccines.

Women do not apply to 'male-sounding' job postings

This news release is available in German.

"We don't have many women in management roles because we get so few good applicants." Companies can be heard lamenting this state of affairs with increasing frequency. Just an excuse? Scientists from the TUM have discovered something that actually does deter women from applying for a job, even if they are qualified: the wording of the job ads.
