Sea turtles face plastic pollution peril

A new global review led by the University of Exeter that set out to investigate the hazards of marine plastic pollution has warned that all seven species of marine turtles can ingest or become entangled in the discarded debris that currently litters the oceans.

Identified an 'alarm clock' of a leukemia-causing oncogene

of IDIBELL, ICREA researcher and Professor of Genetics at the University of Barcelona, shows how a mutation in a gene results the activation of a gene that triggers leukemia.

"Recently it has been discovered the existence of mutations in the DNMT3A gene in leukemia. It seemed that history stopped here. But this gene is responsible for silencing other genes that should not be active in the cell; so we wonder which DNA sequence was being "awakened" by this mutation in leukemias "explained Manel Esteller, director of the study.

IQWiG publishes English translation of the new version of its General Methods

The English translation of the new version of the methods paper (General Methods 4.2) by the German Institute for Quality and Efficiency in Health Care (IQWiG) is now available on iqwig.de. The German-language original was published on 22 April 2015. Since then, the new methods paper has been the basis for the scientific work of the Institute and its external experts as well as for the Institute's collaboration with its contracting agencies.

A multilaminar model explains the structure of chromosomal aberrations in cancer cells

During cell division, each metaphase chromosome contains a single enormously long DNA molecule that is associated with histone proteins and forms a long chromatin filament with many nucleosomes. Current chromosome models consider that chromatin is folded forming loops or irregular networks.

One groups pays more for health insurance under ObamaCare - tobacco users

A new study finds tobacco users pay more for a health insurance plan from the Affordable Care Act exchanges than non-tobacco users in nearly every county of the 37 states that used healthcare.gov to sell their plans in 2015.

In some instances, up to 46% more. The authors say future research may determine how many enrollees facing these surcharges will simply decide not to be truthful about their smoking status, or perhaps avoid buying health insurance altogether. The study appears early online in the American Journal of Public Health.

Study links fracking to 4 percent greater chance of premature birth

Expectant mothers who live near active natural gas wells operated by the fracking industry in Pennsylvania are at an increased risk of giving birth prematurely and for having high-risk pregnancies, new Johns Hopkins Bloomberg School of Public Health research suggests.

How small is the smallest? New record of the tiniest free-living insect provides precision

The long-lasting search and debate around the size and identity of the World's smallest free-living insect seems to have now been ended with the precise measurement and second record of the featherwing beetle species.

Surgeons restore hand, arm movement to quadriplegic patients

A pioneering surgical technique has restored some hand and arm movement to patients immobilized by spinal cord injuries in the neck, reports a new study at Washington University School of Medicine in St. Louis.

Seeing in a new light

An animal's ability to perceive light incorporates many complex processes. Now, researchers in Craig Montell's lab at UC Santa Barbara have used fruit flies and mice to make novel discoveries about sensory physiology at both cellular and molecular levels that are important for light processing.

Menopause diminishes impact of good cholesterol

CLEVELAND, Ohio (October 8, 2015)--What has previously been known as good cholesterol--high density lipoprotein (HDL)--has now been shown to be not so good in protecting women against atherosclerosis while they are transitioning through menopause. That's according to a new study from the University of Pittsburgh Graduate School of Public Health that was presented last week at the annual meeting of The North American Menopause Society (NAMS) in Las Vegas.

Researchers create 'leukemia in a dish' to better study it

Scientists engineered stem cells to better understand the mechanisms behind a form of leukemia caused by changes in a key gene, according to a study led by Mount Sinai researchers and published online today in the journal Cell Reports.

Past work had established that inherited changes in the DNA code for the gene PTPN11 cause Noonan syndrome, a genetic disease that comes with a high risk for the blood cancer called juvenile myelomonocytic leukemia (JMML). The mechanisms behind the disease, and what influences its severity, were unknown going into the current study.

'This enormous burden': Controlling cervical cancer in Latin America

The latest Special Issue from ecancermedicalscience collects four new research articles on the topic of cervical cancer prevention in Latin America.

Cervical cancer is an "enormous burden" for Latin American society, and the third leading cause of cancer deaths among women in the region, say Guest Editors Dr María Correnti and Dr María Eugenia Cavazza of the Central University of Venezuela, Caracas, Venezuela.

FIGO calls for treatment developed at Wayne State to fight worldwide preterm birth

Recommendations to reduce the rates of preterm birth developed at the Wayne State University School of Medicine and the National Institutes of Health's Perinatology Research Branch were introduced as worldwide best practices in maternal-fetal health Thursday during the World Congress of the International Federation of Gynecology and Obstetrics in Vancouver.

UNC-Chapel Hill researchers reveal type of vaginal bacteria that protects women from HIV

Researchers at the University of North Carolina at Chapel Hill have identified a type of vaginal bacteria within the mucus of the female reproductive system that can protect women from HIV as well as other sexually transmitted infections.

Molecular characteristics of mammalian melanopsins for non-visual photoreception

Researchers at Institute for Molecular Sciences reported that a mammalian photoreceptive protein melanopsin spontaneously releases the chromophore retinal. The property would be important to regulate non-visual photoreception in mammals. This work was carried out as a collaborative work of Drs. Hisao Tsukamoto and Yuji Furutani (Institute for Molecular Science) with Yoshihiro Kubo (National Institute for Physiological Sciences), David Farrens (Oregon Health and Science University), Mitsumasa Koyanagi and Akihisa Terakita (Osaka City University).
