The link between sleep problems and suicidal thoughts and behaviors is made starkly clear in new research.
Especially in late summer, apprehension about wasp stings increases among allergy sufferers. So-called hyposensibilization therapy can help, but it is linked to a heavy burden on patients and health insurers. Researchers have now presented a new method which facilitates a personalized procedure.
Scientists have found Ebola's Achilles' heel: a new kind of chemical compound can block the protein Ebola uses to break out of cells and infect new cells. The compounds could potentially be used to treat the disease after infection.
Childhood brain injuries, including concussions, are associated with an increased risk of subsequent mental illness, poor school attainment and premature death, according to a new study.
Nutritional stress is a normal part of life; going hungry on a short-term basis generally does not impair important functions. The brain coordinates the response to nutritional stress but how it does this was, until now, not well understood. Researchers have now discovered a brain circuit that allows fruit flies to take a major developmental step in their lives despite nutritional stress.
Targeting certain donor cells lowered the risk of organ rejection in mice that underwent kidney and heart transplants. Results of this new study could lead to new ways of preventing or treating organ transplant rejection in humans.

Understanding what counts as an addiction, and what can be done to address it is the work of researchers across many disciplines. But what tools are used to ‘measure’ addiction, and are these capable of legitimising an addiction or improving our knowledge of it?
In a very severe, genetic form of microcephaly, stem cells in the brain fail to divide, according to a new study that may provide important clues to understanding how the Zika virus affects the developing brain.
New research questions the strong claims that have been made about the benefits of 'brain training' -- enhanced mental skills, a boost to education, improved clinical outcomes and sharper everyday functioning. This new study found evidence that 'brain training' changed brain signalling but no indication of other benefits.
Female triathletes are at a higher risk for several health issues, including pelvic floor disorders, new research indicates. Researchers conducted an internet survey of 311 self-identified female triathletes. Results showed a significant prevalence of pelvic floor disorders, with urinary incontinences (37.4 percent) and anal incontinence (28.0 percent) being the most common.
A surgery for quadriplegics called tendon transfer can significantly improve hand and elbow function, but the procedure is greatly underused, according to a new article.
Researchers show, for the first time, that the well-known mechanism of gene expression control -- dynamic changes in DNA methylation -- is also involved in changes to the excitability of neural cells. This suggests that DNA methylation changes that alter excitability may be a mechanism involved in neuropsychiatric disorders, and that the sites of such changes may offer a potential therapeutic target.
Researchers have seen significant increases in the number of Americans who can afford to fill prescriptions following implementation of the 2003 Medicare Modernization Act and the 2010 Affordable Care Act (also called Obamacare).
Standing desks lower the BMI trajectory in elementary-aged children over a two-year span--by an average of 5.24 percentile points, a landmark study has found.
Faculty teaching in the STEM disciplines at large research universities are devising their own systems to collect instructional data from their classrooms and using that data to inform their teaching.
Researchers have developed in collaboration with French colleagues a small device that both detects the initial signal of an epileptic attack and doses a substance that effectively stops it. All this takes place where the signal arises -- in an area of size 20chr('215')20 μm known as a 'neural pixel.'
A recent study published by Brazilian researchers indicates brain malformations induced by Zika virus congenital infection. More than microcephaly, the research indicates other neurological changes such as reduction in brain volume, cortical development abnormalities and ventriculomegaly.
Providing HIV medication to both members of a couple may substantially reduce the risk of transmission within that couple, according to a new study.
Insufficient capacity to perform laboratory tests used in monitoring HIV infection, and underutilization of existing testing capacity, are limiting the ability to meet the Joint United Nations Programme on HIV and AIDS 90-90-90 targets, suggests a new study.
Traumatic brain injury (TBI) during youth is associated with elevated risks of impaired adult functioning, according to a longitudinal study. The study demonstrates that children and adolescents experiencing even milder forms of TBI (including concussion) may have reduced longevity and significant psychosocial problems in adulthood.
The growth of cancerous tumors is affected by the transforming growth factor beta (TGF-beta) in the body’s cells; TGF-beta both suppresses and stimulates tumor development, but it has not been understood how this happens. A new study reveals important details behind this process.
For the first time, a team of researchers has developed and validated a prediction model to determine sudden cardiac death risk in adults without a history of cardiovascular disease (CVD).
Leaving a child unattended is considered taboo in today’s intensive parenting atmosphere, despite evidence that American children are safer than ever. So why are parents denying their children the same freedom and independence that they themselves enjoyed as children? A new study by social scientists suggests that our fears of leaving children alone have become systematically exaggerated in recent decades – not because the practice has become more dangerous, but because it has become socially unacceptable.
Sociologists have found that teachers often inadvertently translate students' class-based behaviors into unequal opportunities in school. Teachers favor middle-class students in various ways, perhaps unconsciously.
Too much manganese early in development causes lasting attention deficits and other impairments in rats. Studies of children and adolescents have associated excess manganese in the diet with attention deficits, but confounding factors in those studies have made it impossible to show a cause and effect relationship. The new study is the first to establish a causal link between exposure to elevated manganese in the diet and attentional dysfunction in an animal model.
While guaranteed-tuition laws, such as the one in Illinois, may provide predictability for incoming in-state students for their first four years, these mandates inadvertently trigger substantial tuition and fee increases, making higher education more costly and possibly unaffordable for some students, say authors of a new report.
A study from AIDS researchers shows how the expected disease severity when someone is newly infected by HIV reflects a balance between the virus' invisibility to the host's immune system and its ability to reproduce.
Researchers have discovered a piece in the puzzle of how sleep deprivation negatively affects memory.
Music can have important effects on the cooperative spirits of those exposed to music, researchers report. A new article describes two studies they conducted to test the effect of different types of music on the cooperative behavior of individuals working as a team.
The Swedish National Board of Health and Welfare recently raised the recommended target blood pressure for patients with diabetes. This may lead to more patients suffering from stroke or heart attack, according to a new study. The new study is the world's largest on the subject and is based on data from the National Diabetes Register.
Researchers from the epicenter of the current Zika virus outbreak have released a report on imaging findings in babies and fetuses infected with the Zika virus. Zika virus is most dangerous when transmitted from a pregnant mother to her fetus, increasing the likelihood of severe brain defects in the baby. In addition to microcephaly, the report identifies a wide array of brain defects, visible on CT, MRI and ultrasound.
According to most current guidelines, treatment for osteoporosis is recommended in individuals with prior fragility fractures -- however for those without prior fractures, intervention thresholds using FRAX can be derived using different methods.
A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.
We all know that a brush with poison ivy leaves us with an itchy painful rash. Now researchers have discovered the molecular cause of this irritation. The finding brings us a step closer to designing agents to block this mechanism and sheds light on other serious skin conditions, such as psoriasis.
Scientists have investigated the role of the ghrelin receptor, growth hormone secretagogue receptor, or GHSR, in age associated adipose tissue inflammation and insulin resistance in mice.
A research team combined a protein that stimulates bone formation with a peptide that promotes osteoblast differentiation, and delivered them into mouse jawbones by injection within a gelatin carrier. The technique induced formation of new bone, suggesting its potential as a non-invasive means of replacing lost jawbone.

As the US experiences sharp increases in drug overdoses, researchers are using geo-mapping to look at the state, neighborhood by neighborhood, to identify 'hot spots' where the use of prescription fentanyl -- an extremely powerful synthetic opiate, which recently attracted national attention as the drug that caused Prince's death -- and other opiates is especially prevalent.
Non-toxic, edible batteries could one day power ingestible devices for diagnosing and treating disease. One team reports new progress toward that goal with their batteries made with melanin pigments, naturally found in the skin, hair and eyes.
A study of women receiving hormone therapies such as tamoxifen as part of their treatment for breast cancer has found that the number and seriousness of side effects they experienced were influenced by their expectations. The study found that women who had higher expectations of suffering more and worse side-effects before their treatment began did, in fact, experience more after two years of adjuvant hormone therapy.
Doctors have warned musicians who play wind instruments of a potential hazard they have dubbed 'bagpipe lung.'
UK deaths from heart disease and stroke have plummeted by almost 70 percent over the past 30 years, but these improvements have not been equally distributed among all four countries, or between men and women, finds an analysis of the available data.
Researchers have identified a previously unknon role of a cellular signaling molecule involved in release of the 'hunger hormone' ghrelin, a finding that could have implications for optimal treatment of children taking beta blockers.
Similarly to cars, cells need a steering mechanism that guides them towards a certain target or direction. Scientists have discovered the function of a key protein involved in cells' movement and clarified how cells migrate. These findings provide a deeper understanding of cells' movement and can benefit several biological fields, such as cancer, immunological and neurological research.
