July 20, 2016 - Programs to reduce the high risk of HIV infection among transgender people are urgently needed -- but efforts are hindered by a lack of accurate information on HIV prevalence, HIV incidence, and specific risk factors facing this key population. A special supplement to JAIDS: Journal of Acquired Immune Deficiency Syndromes presents essential information to meet the challenges of HIV prevention in the transgender population.

The collaboration between the research groups of professors Pau Ballester and José R. Galan-Mascaros at the Institute of Chemical Research of Catalonia (ICIQ), Dr. Jonas Björk at Linköping University and the group of Dr. David Ecija at Institute IMDEA Nanoscience has allowed the development of a new chemical reaction for the synthesis of low-dimensional polymers that can be rationalised as phthalocyanine derivatives. The results obtained have been published in Nature Communications.

Across many cancer types, obese patients fare worse than leaner patients. Now a University of Colorado Cancer Center study published in the journal Cell Stem Cell offers a compelling hypothesis why: researchers found that leukemia stem cells "hide" in fatty tissue, even transforming this tissue in ways that support their survival when challenged with chemotherapy. It is as if leukemia stem cells not only use fatty tissue as a robbers' cave to hide from therapy, but actively adapt this cave to their liking.

ROCHESTER, Minn. -- Researchers at the Mayo Clinic Center for Individualized Medicine have found a promising new way to monitor and treat recurrence of ovarian cancer -- a hard-to-detect disease that claims many lives. New research from George Vasmatzis, Ph.D., of the Department of Laboratory Medicine and Pathology at Mayo Clinic, finds liquid biopsies from blood tests and DNA sequencing can detect a return of ovarian cancer long before a tumor reappears. That could lead to earlier intervention and more effective, individualized treatment. Dr.

Getting more for less is an attractive concept. But it isn't that easy when it comes to producing more food on less land with fewer resources.

R. Howard Skinner has been researching this idea of more for less in agriculture. Skinner is a physiological plant ecologist and member of the USDA-ARS-Pasture Systems and Watershed Management Research Unit. He's been looking into how to increase the amount of forage (grasses and plants that animals eat) pastures can grow. If a piece of land can produce more forage, it can feed more cows. More cows mean more beef and milk.

LA JOLLA, CA - July 20, 2016 - In a new study, scientists at The Scripps Research Institute (TSRI) have identified drug candidates that can boost a cell's ability to catch the "typos" in protein production that can cause a deadly disease called amyloidosis.

"This study reveals a new approach to intervene in human disease," said Luke Wiseman, assistant professor at TSRI and co-senior author of the new research with Jeffery Kelly, Lita Annenberg Hazen Professor of Chemistry at TSRI.

The research was published today in the journal eLife.

MADISON, Wis. -- Although most of the terrestrial world is covered in trees, there are precious few vertebrates that make the canopy their home and subsist solely on a diet of leaves.

Tree sloths are among the most emblematic tree-dwelling mammals. However, they are best known for their pokey demeanor rather than the fact that they spend the majority of their lives in trees munching leaves. But the slow motion lifestyle of tree sloths, according to a new study, is the direct result of the animal's adaption to its arboreal niche.

New York, NY (July 20, 2016)--Adding a novel monoclonal antibody therapy to traditional chemotherapy increased median survival by nearly a year in patients with advanced sarcoma, a lethal soft-tissue cancer. Findings from a multicenter clinical trial of the combination therapy, led by researchers at Columbia University Medical Center and NewYork-Presbyterian, represent the first appreciable improvement in sarcoma outcomes in decades.

The study was published online earlier this month in The Lancet.

CHAMPAIGN, Ill. -- A new study from the University of Illinois confirms a link between Pap smear screenings and a lower risk of developing cervical cancer in women over age 65. However, most American health guidelines discourage women in that age range from receiving screenings unless they have pre-existing risk factors.

The new findings are published in the journal Gynecologic Oncology.

A new scientific study has identified why colorectal cancer cells depend on a specific nutrient, and a way to starve them of it. Over one million men and women are living with colorectal cancer in the United States. The National Cancer Institute estimates 4.5% of all men and women will be diagnosed with the cancer during their lifetime, making it the third most common non-skin cancer.

Jamie Oliver's back-to-basics approach to improving our diets works, according to a new study. Researchers at the University of Leeds found that men and women who attended one of the celebrity chef's eight-week Ministry of Food courses showed significant improvements in their eating habits.

The participants greatly increased their intake of fruit and vegetables, halved the amount of snacks they ate and became much more confident about their cooking skills, the nutritionists found.

A major new analysis from the Global Burden of Disease 2015 (GBD 2015) study, published today in The Lancet HIV journal, reveals that although deaths from HIV/AIDS have been steadily declining from a peak in 2005, 2.5 million people worldwide became newly infected with HIV in 2015, a number that hasn't changed substantially in the past 10 years.

A scientist from the University of Exeter has helped to identify a male-killing microbe in a tropical butterfly called the African Queen, which leads to the death of all sons when a mother is infected.

An international collaboration between the University of Oxford and other European institutions has uncovered a correlation between a rare mutation in bowel cancers and a better prognosis, raising the possibility that patients with such tumours may not require chemotherapy after surgery.

DURBAN (July 19) - AIDS deaths are falling in most countries worldwide, but the rate of new infections increased in several countries over the past decade, threatening to undermine efforts to end the AIDS epidemic by 2030, a new scientific paper shows.

The study from the Global Burden of Disease collaborative network, published today in The Lancet HIV, found that 74 countries saw increases in age-standardized rates of new infections between 2005 and 2015, including Egypt, Pakistan, Kenya, the Philippines, Cambodia, Mexico, and Russia.
