Do bad dreams serve a real purpose? To answer this question, researchers from the University of Geneva (UNIGE) and University Hospitals of Geneva (HUG), Switzerland, - working in collaboration with the University of Wisconsin (USA) - analysed the dreams of a number of people and identified which areas of the brain were activated when they experienced fear in their dreams. They found that once the individuals woke up, the brain areas responsible for controlling emotions responded to fear-inducing situations much more effectively.
Climate change is reshaping communities of fish and other sea life, according to a pioneering study on how ocean warming is affecting the mix of species.
The study, published in the journal Nature Climate Change, covers species that are important for fisheries and that serve as food for fish, such as copepods and other zooplankton.
Microorganisms are considered as dirty organism that threaten our health, decay food and cause inconvenience in our daily life. However, they are playing a critical role in making nutrients by metabolizing food, allowing all living creatures to live on. Especially, there are 2,000 kinds of microorganisms and several hundred trillions in figures living in our body. Most of these microorganisms live in digestive tracts but their effect is shown in our entire body.
EAST LANSING, Mich. -- Salmonella is acting up in Michigan, and it could be a model for what's happening in other states, according to a new Michigan State University study.
The study, appearing in Frontiers in Medicine, documents a substantial uptick in antibiotic resistant strains, and consequently, longer hospital stays as doctors work to treat the increasing virulent pathogens.
The study, which looks specifically at the behaviour of an endangered monkey species, reveals that even in national parks where human presence is reduced and regulated, the animals carry out careful calculations and modify their natural behaviour to balance the pros and cons of living in close proximity to humans.
It reveals the negative impact that consuming human foods can have on the physical health of the monkeys, and highlights the need for new and sustainable conservation programmes to save the growing number of endangered species in their natural habitats.
Climate change is reorganizing the life in our oceans in a big way: as waters warm, cold-loving species, from plankton to fish, leave the area and warm water species become more successful. So say an international group of scientists in the most comprehensive assessment of the effects of ocean warming on the distribution fish communities.
Boston, MA -- Obstructive sleep apnea (OSA) has been considered a predominantly male disease. While more women have been diagnosed with OSA in recent years, the numbers remain disproportionate, with 3-to-5 times more men than women receiving an OSA diagnosis. Investigators from Brigham and Women's Hospital and Yale School of Medicine set out to understand this disparity and its causes. They found that a high proportion of women experienced sleep apnea during dream sleep, which is associated with adverse outcomes including cardiovascular disease.
Although the cilium has been known to scientists for more than 100 years, it is only recently that it has been acknowledged to play important roles in physiology. Virtually every cell has a primary cilium that functions to senses fluid flow, transmits chemical signals to other cells and controls cell growth. Defects in the function of cilia lead to a class of diseases called ciliopathies, which include polycystic kidney disease, primary ciliary dyskinesia and Bardet-Biedl syndrome.
CHICAGO - Researchers using MRI have found signs of damage that may be related to inflammation in the brains of obese adolescents, according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).
CHICAGO - Connectivity in an area of the brain that regulates emotion may be altered in infants exposed to opioids while in utero, according to a new study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).
Nonpowder firearms have long been marketed to children and teenagers as toys or "starter" firearms and include BB, pellet, airsoft and paintball guns. A new study conducted by researchers at the Center for Injury Research and Policy of the Abigail Wexner Research Institute at Nationwide Children's Hospital investigated nonpowder firearm injuries treated in U.S.
Two genes that appear to help stem cells in the intestine burn dietary fat may play a role in colon cancer, according to a Rutgers study.
The study, published in the journal Gastroenterology, describes a new connection between the way cells consume fat and how genes regulate stem cell behavior in the intestines of mice.
ASPB is pleased to announce the publication of research with significant implications for nitrogen nutrition in crop plants.
Researchers Karnelia Paul of the University of Calcutta (India), Chinmay Saha of the University of Kalyani (India), and Anindita Seal of the University of Calcutta (India) designed this research to study nitrogen nutrition in rice.
Living beings, especially microorganisms, have a surprising ability to adapt to the most extreme environments on our planet, but there are still places where they cannot live. European researchers have confirmed the absence of microbial life in hot, saline, hyperacid ponds in the Dallol geothermal field in Ethiopia.
Researchers of the Faculty of Science of the University of Malaga (UMA) have designed a low-cost T-shirt that generates electricity from the temperature difference between the human body and the surroundings. We are talking about the "e-textile" prototype, developed in collaboration with the Italian Institute of Technology in Genoa (IIT) based on sustainable methods and low-cost materials like tomato skin.
