Amsterdam, June 14, 2016 - Tiny bubbles filled with the sleep hormone melatonin can make breast cancer treatment more effective, which means people need a lower dose, giving them less severe side effects. In a new study published in Colloids and Surfaces B: Biointerfaces, researchers show that the bubbles, called nanostructured lipid carriers (NLCs), made tamoxifen stronger and help it kill cancer cells.

A few weeks ago, the biologist Juliano Sarmento Cabral (33) celebrated a handsome success. Together with former colleagues from the University of Göttingen, he published an article in the journal Nature. One finding: In order to understand the diversity of species on islands such as Hawaii, Galapagos or the Canary Islands, you have to look far back into the past - at least as far as the last ice age 21,000 years ago.
One of the most fundamental goals in ecology - determining the community assembly processes that have structured local communities - has been increasingly studied through the analysis of functional and phylogenetic diversity.
Neuherberg, June 14, 2016. Scientists at the Helmholtz Zentrum München and the Ludwig Maximilians University of Munich (LMU) have developed a new method of predicting disease progression in gliobastoma patients who have undergone standard treatment. Their findings, published in the journal Oncotarget, show that four miRNAs may hold the vital clue. An application for the corresponding patent has already been filed.
The first days after HIV infection are very important because sexual partners are exposed to extremely high risks of infection due to the subsequent high viral load in the infected person. Additionally, this period of time determines the further course of HIV infection.
"The affected countries will have a major problem if we do not manage to control salmonella bloodstream infections with new antibiotics such as ciprofloxacin," cautions Prof Jürgen May. He has conducted numerous studies on salmonella infections in sub-Saharan Africa, particularly in Kumasi in Ghana, where the Bernhard Nocht Institute and the DZIF are in close partnership with researchers from the Kumasi Centre for Collaborative Research in Tropical Medicine.
PROVIDENCE, R.I. [Brown University] -- As Brazilians make final preparations to host the world's premier showcase of athleticism, the Olympics, a new paper in the Journal of the American Heart Association reports that many citizens of the host country are not taking enough advantage of the health benefits of exercise.
New York, NY--June 14, 2016--Columbia Engineering Professor Steven K. Feiner and Ajoy Fernandes MS'16 have developed a method of combating virtual reality (VR) sickness that can be applied to consumer head-worn VR displays, such as the Oculus Rift, HTC Vive, Sony PlayStation VR, and Google Cardboard. Their approach dynamically, yet subtly, changes the user's field of view (FOV) in response to visually perceived motion, as the user virtually traverses an environment while remaining physically stationary.
The dangers of arterial thrombosis - the formation of blood clots that can block arteries and cause illness or death - can escalate through a vicious cycle of coagulation and inflammation. But microRNAs - single-stranded, non-coding small RNAs that can tamp down signaling from specific genes - may be able to break this cycle. In previous studies, researchers from Brigham and Women's Hospital found that microRNA-181b (miR-181b) could regulate acute and chronic vascular inflammation.
(June 14, 2016 - Lakeville-Middleboro, Mass) - Today leading experts on infectious disease and urinary tract infections (UTIs) will gather in London to discuss the alarming state of antibiotic resistance, and present findings from a landmark study that conclusively shows that cranberries can be a nutritional approach to reducing symptomatic UTIs, and as a result, may be a useful strategy to decrease worldwide use of antibiotics.
PRINCETON, N.J.--As incarceration rates have increased in the United States, so has the likelihood that children will endure the imprisonment of a parent -- especially among the most disadvantaged populations. But how does the imprisonment of parents and other household members influence a child or adolescent's future?
This paves the way to fast and energy efficient ultrahigh density data storage. The results are published now in the new journal Physical Review Applied.
Citizen journalism is often seen as a more democratic form of journalism, where the public contributes to the reporting, analysis and dissemination of news. Sociologist and criminologist Agneta Mallén at Lund University in Sweden has studied the phenomenon and shown some of its downsides, including how it sometimes leads to outright cyber bullying.
CHAPEL HILL, NC - Researchers have shown that the glucose-lowering drug liraglutide safely and effectively decreases the overall risk of heart attack, stroke, or cardiovascular death for people with type 2 diabetes. These patients are at high risk for cardiovascular disease, which is the number one killer of people with type 2 diabetes. Liraglutide was also associated with a reduction in kidney disease and death from all causes.
The female Chinese Hume Warbler is attracted to males who sing simple songs, as opposed to the more common preference among birds of choosing males who sing the most complex songs. This preference for males with inconspicuous songs may be related to nesting behavior and driven by the threat of predation, according to research published in the open access journal Avian Research.
