Women who experienced six or more symptoms of post-traumatic stress disorder (PTSD) at some point in life had a twofold greater risk of developing ovarian cancer compared with women who never had any PTSD symptoms, according to a new study from researchers at Harvard T.H. Chan School of Public Health and Moffitt Cancer Center.
The brain stores memories through a neuronal ensemble, termed engram cells. A unique system was established to transfer neuronal population activity into light with discrimination between engram and non-engram cells using fluorescence proteins. By using this system, it is revealed that engram sub-ensembles represent distinct pieces of information, which are then orchestrated to constitute an entire memory. In addition, some sub-ensembles preferentially reappear during post-learning sleep, and these replayed sub-ensembles are more likely to be reactivated during retrieval.
Increased consumption of sugar-sweetened and artificially sweetened soft drinks is associated with an increased risk of death. This is the main conclusion reached by a study based on 16-year follow-up of about 452,000 participants, male and female, from 10 European countries. Researchers from the Nutrition and Cancer group of the Catalan Institute of Oncology (ICO) and the Bellvitge Biomedical Research Institute (IDIBELL) have contributed to the findings.
Forests with a large variety of species are more productive and stable under stress than monocultures: scientists from the University of Freiburg have confirmed this with data from the world's oldest field trial on the diversity of tropical tree species. The team around PhD student Florian Schnabel has published its results in the journal Global Change Biology.
A research team of the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona has sequenced the genome of the spider Dysdera silvatica Schmidt 1981, an endemic species living in the laurel forests in the islands La Gomera, La Palma, and El Hierro -in the Canary Islands (Spain).
The new study reveals the first genome sequencing of an arthropod in the Canary Islands, an archipelago with a rich biodiversity regarding endemic species that are distributed around the insular area.
An individual's premarital views about uncommitted sex may make it more difficult to remain blissfully married, according to research published in Psychological Science, a journal of the Association for Psychological Science.
The research outlines several factors that can contribute to a marriage's long-term happiness or dissolution, including one big red flag: An individual's behaviors and attitudes about uncommitted sexual relationships even before the marriage.
A new study, presented as 'Late Breaking Science' at the European Society of Cardiology (ESC) annual congress and published in the Journal of the American College of Cardiology, highlights the feasible use of mobile health (mHealth) devices to help with the screening and detection of a common heart condition.
Bacteria are becoming increasingly resistant to common antibiotics. Often, resistance is mediated by resistance genes, which can simply jump from one bacterial population to the next. It's a common assumption that the resistance genes spread primarily when antibiotics are used, a rationale backed up by Darwin's theory: only in cases where antibiotics are actually being used does a resistant bacterium have an advantage over other bacteria. In an antibiotic-free environment, resistant bacteria have no advantage.
Better conservation and management of fish stocks is on the horizon, after the completion of the brown trout reference genome by scientists at the Wellcome Sanger Institute and their collaborators. The genome will help settle a longstanding debate about whether the physically-varied brown trout is actually a single species or several, and give insights into their ability to quickly adapt to multiple environments.
HOUSTON -- Researchers at The University of Texas MD Anderson Cancer Center have confirmed a protein as an oncogene responsible for the most common and lethal form of pancreatic cancer known as pancreatic ductal adenocarcinoma (PDAC). The team's findings, which validated ubiquitin specific protease 21 (UPS21) as a frequently amplified gene and a potential druggable target, appear in the Sept. 5 online issue of Genes & Development.
Many people have experienced stressful situations that trigger a particular mood and also change certain feelings toward food. An international team led by researchers at Baylor College of Medicine looked into the possibility of crosstalk between eating and mood and discovered a brain circuit in mouse models that connects the feeding and the mood centers of the brain.
Study shows ground floor-based businesswomen doubled their income, narrowed the gender earnings gap by more than half.
Toronto - The gender earnings gap has proven to be a hard nut to crack around the world and it's just as prevalent in strategies designed to lift women out of poverty in developing countries.
Medicare often spends $3,590 for an individual's 30-day prescription after adjusting for all rebates, and prices continue to rise.
BIRMINGHAM, Ala. - Beta cells in pancreatic islets produce insulin to exquisitely regulate blood glucose levels and, thus, provide energy to cells throughout the body. Loss or dysfunction of the beta cells results in diabetes, a major public health threat that can lead to heart disease, neuropathy, blindness and kidney failure.
Research by an international team of scientists shed new light to the nutritional quality of whitefish and revealed that the tasty fish is best to eat in late summer. Whitefish growth and spawning cycles lead to differences in both fish condition and nutritional quality. The measurements done in the research showed that European whitefish muscle omega-3 fatty acid concentration declined by 60 percent from the end of the growing season to the spawning time in winter.
