Results of the first study of its kind to link abnormalities in circadian rhythms to changes in specific neurotransmitters in people with bipolar disorder will be published this week in the journal Biological Psychiatry.
A new study published in Diabetologia (the journal of the European Association for the Study of Diabetes [EASD]) shows that children with a strong family history of cardiovascular disease (CVD) and/or type 2 diabetes were found to have cholesterol levels significantly higher than children with no family history of those conditions.
Scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory are playing a central role as the nation devotes more than $500 million to understand communities of microorganisms and their role in climate science, food production and human health.
New research presented at Euroanaesthesia 2016 (London 27-30 May) shows that patients undergoing breast cancer surgery need less painkilling medication post-surgery if they have anaesthesia that is free of opioid drugs.
The waters surrounding Antarctica may be one of the last places to experience human-driven climate change.
Zika virus can infect and replicate in immune cells from the placenta, without killing them, scientists have discovered. The finding may explain how the virus can pass through the placenta of a pregnant woman, on its way to infect developing brain cells in her fetus.
One of Zika's mysteries is how the virus passes from an infected mother, through the placenta, to a developing fetus.
250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean.
Just as members of an orchestra need a conductor to stay on tempo, neurons in the brain need well-timed waves of activity to organize memories across time. In the hippocampus--the brain's memory center--temporal ordering of the neural code is important for building a mental map of where you've been, where you are, and where you are going.
A study of the content of rare earth elements in U.S. coal ashes shows that coal mined from the Appalachian Mountains could be the proverbial golden goose for hard-to-find materials critical to clean energy and other emerging technologies.
One of the most striking discoveries of quantum information theory is the existence of problems that can be solved in a more efficient way with quantum resources than with any known classical algorithm.
The toxic dinoflagellate, Alexandrium fundyense, is a photosynthetic plankton--a microscopic organism floating in the ocean, unable to swim against a current.
Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells' ability to proliferate and replace damaged heart tissue.
A benign virus normally found in the skin can lead to a type of rare, lethal skin cancer. Specifically, infection by the Merkel cell polyomavirus can lead to Merkel cell carcinoma in immune-compromised individuals.
A type of flatworm could be a new weapon in the hunt for better ways to treat a group of diseases that can cause extreme sensitivity to light, facial hair growth, and hallucinations, according to a study published in the journal eLife.
Oncologists at the Fred Hutchinson Cancer Research Center have successfully treated a patient with metastatic melanoma by combining two different types of immunotherapy.
Countries that implement government-mandated vaccinations for chickenpox see a sharp drop in the number of Google searches for the common childhood disease afterward, demonstrating that immunization significantly reduces seasonal outbreaks.
People have always wondered why many birds lay bright blue eggs. David Lahti of the City University of New York and Dan Ardia of Franklin & Marshall College tested the hypothesis that pigmentation might help an egg strike a balance between two opposing and potentially damaging effects of the sun: light transmission into light-colored eggs, and heating up of dark-colored eggs.
Chronic stress can make us worn-out, anxious, depressed--in fact, it can change the architecture of the brain. New research at The Rockefeller University shows that when mice experience prolonged stress, structural changes occur within a little-studied region of their amygdala, a part of the brain that regulates basic emotions, such as fear and anxiety.
Bipolar disorder (BD) is a severe and complex mental illness with a strong genetic component that affects 2% of the world population. The disorder is characterized by episodes of mania and depression that may alternate throughout life and usually first occur in the early 20s.
Cardiac complications are the number one cause of death among diabetics. Now a team of scientists has uncovered a molecular mechanism involved in a common form of heart damage found in people with diabetes.
Researchers can build complex, nanometer-scale structures of almost any shape and form, using strands of DNA. But these particles must be designed by hand, in a complex and laborious process.
Research by Dr. Shernaz Bamji, from the University of British Columbia, uncovers the mechanism of action of an enzyme called DHHC9 in the normal development and function of neural networks in the brain.
With climate change already close to an irreversible tipping point, urgent action is needed to reduce not only our mean (carbon) footprints but also the "number of feet" - that is, the growing population either already creating large footprints or aspiring to do so, argues a leading physician and environmentalist in The BMJ today.
A team of scientists from across the globe have shown that the brains of patients with schizophrenia have the capacity to reorganize and fight the illness. This is the first time that imaging data has been used to show that our brains may have the ability to reverse the effects of schizophrenia.
Technologies that make it harder for people to abuse opioids - like doctoring pills so that they produce unpleasant side effects if broken, crushed or injected -- likely will have limited effectiveness in stemming the global epidemic of opioid abuse, according to Adam Kaye, a professor of pharmacy at University of the Pacific.
Among the many important processes that happen during a woman's last few weeks of pregnancy is the transfer of calcium to the growing foetus to boost bone development. But what happens if this transfer is interrupted when a baby is born prematurely?
Tiny, vibrating hairs may explain how bumblebees sense and interpret the signals transmitted by flowers, according to a study by researchers at the University of Bristol.
A region of the brain that responds to bad experiences has the opposite reaction to expectations of aversive events in people with depression compared to healthy adults, finds a new UCL study funded by the Medical Research Council.
Testing cancers for 'addiction' to a gene that boosts cell growth can pick out patients who may respond to a targeted drug under development, a major new study reports.
A U of T Engineering team has designed a simpler way to keep therapeutic proteins where they are needed for long periods of time. The discovery is a potential game-changer for the treatment of chronic illnesses or injuries that often require multiple injections or daily pills.
A new tool by Japan-based researchers predicts the risk of Zika virus importation and local transmission for 189 countries.
Babies find it easier to learn words with repetitive syllables rather than mixed sounds, a study suggests.
Early exposure to nicotine can trigger widespread genetic changes that affect formation of connections between brain cells long after birth, a new Yale-led study has found. The finding helps explains why maternal smoking has been linked to behavioral changes such as attention deficit and hyperactivity disorder, addiction and conduct disorder.
A new study found that military service members who reported insomnia symptoms or short sleep durations were less resilient than members who reported healthy sleep hygiene.
The consumer marketplace is flooded with a lively assortment of smart wearable electronics that do everything from monitor vital signs, fitness or sun exposure to play music, charge other electronics or even purify the air around you -- all wirelessly.
Research from North Carolina State University and Ohio University finds that having an "alcohol identity" puts college students at greater risk of having drinking problems - and that posting about alcohol use on social media sites is actually a stronger predictor of alcohol problems than having a drink.
While the latter half of the 20th century showed a widening gap between the more and less educated with respect to marriage and fertility, this trend has not significantly altered the genetic makeup of subsequent generations, a team of researchers has found.
The use of next-generation gene sequencing in newborns in neonatal intensive care units (NICUs) may improve the diagnosis of rare diseases and deliver results more quickly to anxious families, according to new research in CMAJ (Canadian Medical Association Journal).
Garbage, nutrients and tiny animals are pushed around, suspended in the world's oceans by waves invisible to the naked eye according to a new 3-D model developed by mathematicians at the University of Waterloo.
About a third of Americans age 50 or older expect to outlive their retirement savings, according to a recent survey by The Associated Press-NORC Center for Public Affairs Research. A majority of older Americans have multiple retirement income sources, but over half say they feel more anxious than secure about the amount of savings they have set aside for retirement.
