Brain activity pattern may be early sign of schizophrenia

Schizophrenia, a brain disorder that produces hallucinations, delusions, and cognitive impairments, usually strikes during adolescence or young adulthood. While some signs can suggest that a person is at high risk for developing the disorder, there is no way to definitively diagnose it until the first psychotic episode occurs.

Study finds new mechanism for regulating sleep in fruit flies using an ingredient commonly found in energy drinks

Sleep is an essential behavioral state in animals ranging from invertebrates to humans. It is critical for immune function, stable metabolism, brain repair, learning and memory. Over the course of a lifetime, more than 30 percent of people will experience a sleep disorder, which is associated with a number of diseases including Alzheimer's, type 2 diabetes, and cardiovascular disease.

Brain signature of depressed mood unveiled in new study

Most of us have had moments when we're feeling down—maybe we can't stop thinking about our worst mistakes, or our most embarrassing memories—but for some, these poor mood states can be relentless and even debilitating. Now, new research from UC San Francisco has identified a common pattern of brain activity that may be behind those feelings of low mood, particularly in people who have a tendency towards anxiety. The newly discovered network is a significant advance in research on the neurobiology of mood, and could serve as a biomarker to help scientists developing new therapies to help people with mood disorders such as depression.

Watch a 3-D-engineered human heart tissue beat

Researchers have developed a way to grow human heart tissue that can serve as a model for the upper chambers of the heart, known as the atria. The tissue, derived from human induced pluripotent stem cells (hiPCSs), beats, expresses genes, and responds to drugs in a manner similar to a real human atrium. The model, described November 8 in the journal Stem Cell Reports, may be useful for evaluating disease mechanisms and drugs for atrial fibrillation—the most common type of arrhythmia.

Automated detection of sleep states from olfactory brain waves

Scientists have developed a completely automated technique for real-time detection of sleep/wake states in freely moving mice. Conducted by Karim Benchenane, Sophie Bagur and colleagues at the National Centre for Scientific Research in Paris, the study, publishing on November 8 in the open-access journal, PLOS Biology, describes how local brain activity in the olfactory bulb is enough to accurately classify mouse vigilance states into wake, REM sleep, and non-REM sleep. The olfactory bulb is a brain structure that transmits information related to the sense of smell to the rest of the brain, and in mice projects forward from under the cerebral cortex, towards the nasal cavity.

Long-term study shows that HIV-2 is deadlier than previously thought

A study published in The Lancet HIV shows that HIV-2 is more pathogenic than previously demonstrated. The new findings indicate that early treatment should be applied to all patients with HIV, not only to those with HIV-1.

A look at how colds and chronic disease affect DNA expression

We're all born with a DNA sequence that encodes (in the form of genes) the very traits that make us, us—eye color, height, and even personality. We think of those genes as unchanging, but in reality, the way they are expressed, or turned into proteins, which are the workhorses of our molecular selves, is regularly in flux.

Using mice, researchers identify how allergic shock occurs so quickly

When someone has a severe allergy, the life-threatening effects of an exposure are nearly instantaneous—skin rash, fainting, labored breathing, weak pulse, racing heart.

Failing heart cells trigger self-protection mechanism

An unexpected finding that links a structural heart protein to gene regulation following heart stress suggests potential new avenues for developing heart failure therapies.

Newborn breastfed babies' saliva combines with breastmilk to release antibacterial compounds that help to shape the bacterial communities (microbiota) in babies' mouths, biomedical scientists have found.

'Orphan' RNAs make cancer deadlier, but potentially easier to diagnose

Scientists have long known that cancer can hijack a cell's existing regulatory circuitry and transform healthy cells into deadly malignancies. But a new discovery from UC San Francisco demonstrates that cancer is more than just a mutineer that seizes control of the cell's administrative operations—it's also a clever engineer, capable of constructing entirely new disease-promoting networks out of raw materials readily available in the cell.

Navigating our thoughts: Fundamental principles of thinking

It is one of the most fundamental questions in neuroscience: How do humans think? Until recently, we seemed far from a conclusive answer. However, scientists from the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) and collaborators offer a new proposal in the current issue of the journal Science—humans think using their brain's navigation system.

Calcifications in the eye increase risk for progression to advanced AMD by more than six times

Calcified nodules in the retina are associated with progression to late stages of age-related macular degeneration (AMD). Experts from Queen's University Belfast, working in partnership with the University of Alabama of Birmingham and in collaboration with UK material scientists and US clinical ophthalmology practices, made the ground-breaking discovery that the calcified nodules in the retina – the thin layer of tissue that lines the back of the eye – increase the risk for progression to advanced AMD more than six times.

A cancer blood test based on DNA fragment size

A team of researchers from the U.K., Denmark, Poland, the Netherlands and Switzerland has developed a new way to test for cancer—by looking at the size of tumor DNA fragments circulating in the bloodstream. In their paper published in the journal Science Translational Medicine, the group describes their technique and how well it worked when tested on patients with different kinds of cancer. Ellen Heitzer and Michael Speicher, with Medical University of Graz, offer a Focus piece on the work done by the team in the same journal issue.

Scientists find that sensory neurons can be used to discover therapies for ALS

Virginia Tech Carilion Research Institute scientists have shown that mutations in specific genes that destroy motor neurons and thereby cause the devastating effects of amyotrophic lateral sclerosis— also known as ALS or Lou Gehrig's disease—also attack sensory neurons.

Recessive genes explain only small fraction of undiagnosed developmental disorders

The Deciphering Developmental Disorders study has discovered that only a small fraction of rare, undiagnosed developmental disorders in the British Isles are caused by recessive genes. The study by researchers from the Wellcome Sanger Institute and their collaborators estimated that only five per cent of the patients had inherited a disease-causing gene mutation from both parents, far fewer than previously thought. This will guide research and could lead to a better understanding of the risk for future pregnancies.

One in five homicides of children two to 14 years of age is related to intimate partner violence

Approximately 20 percent of homicides of children 2 to 14 years of age in the United States may be related to intimate partner violence (IPV), a fact that is currently underreported by the National Violent Death Reporting System (NVDRS), according to a new study from the Harvard T.H. Chan School of Public Health published in the American Journal of Preventive Medicine. The findings will be presented at the American Public Health Association's Annual Meeting in San Diego on November 12, 2018.

Patients with untreated hearing loss incur higher health care costs over time

Older adults with untreated hearing loss incur substantially higher total health care costs compared to those who don't have hearing loss—an average of 46 percent, totaling $22,434 per person over a decade, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health. This is one of the largest studies to look at this issue, following many individuals for a full 10 years. The project was done in collaboration with AARP, University of California San Francisco and OptumLabs.

ThyroSeq test helps patients avoid unnecessary diagnostic thyroid surgery, study shows

A genetic test developed by researchers at UPMC and the University of Pittsburgh School of Medicine can help avoid costly diagnostic surgery that involves removing one or both lobes of the thyroid gland, by reliably distinguishing between benign and cancerous thyroid nodules using a very small sample of cells, according to the results of an international clinical trial published today in the journal JAMA Oncology.

New decision support tool improves discharge outcomes

In an effort to lessen readmission risk after discharge and achieve the best possible outcomes for patients, hospital-based clinicians are more intentionally planning discharge of those who require post-acute care (PAC). Yet, although hospital clinicians strive to effectively refer patients who require PAC, their discharge-planning processes often vary greatly and typically are not evidence-based.

Mobile workers in north Ethiopia vulnerable to visceral leishmaniasis transmission

Visceral leishmaniasis (VL) is a life-threatening disease transmitted by the bite of a sand fly. Between 3,700 to 7,400 people in Ethiopia are infected annually, particularly in the northern, agricultural regions with favorable climate and environment to sand fly vectors. A study published in PLOS Neglected Tropical Diseases by Rebecca Coulborn from Epicentre, France, and colleagues suggests that transitory populations in Ethiopia may be particularly vulnerable to acquisition of and death from VL infections.

Flood dynamics increase population vulnerability to waterborne disease and climate

Diarrheal disease, a preventable and treatable illness, remains the second-leading cause of death in children under the age of 5 and a persistent public health threat in sub-Saharan Africa. Researchers have now uncovered how surface water dynamics may increase the vulnerability of dependent populations to diarrheal disease and climate change.

Pain isn't just physical—why many are using painkillers for emotional relief

Australians are increasingly using prescription or over-the-counter painkillers to ease emotional, rather than physical, pain. Our cultural understanding of pain is changing, and as a result it's becoming more difficult to distinguish intoxication from relief.

Mark your calendar: All infectious diseases are seasonal

Most of us are aware of the seasonal cycle of influenza outbreaks, which for Americans peak in the winter.

Breast cancer follow-up can be less intensive

Doctoral research by Annemieke Witteveen at the University of Twente has shown that the number of follow-up visits for women after breast cancer treatment in the Netherlands could be reduced by about 9,000 visits per year. The follow-up could be offered based on the to the risk of recurrence, so that women with a low risk possible would need to revisit the hospital for a mammogram less frequently. Personalized follow-up reduces the burden on patients, care providers and possible the care budget.

Stressed? Your relationship with your boss may be playing a role

Everybody knows how horrible it is to be stressed out at work. Sadly, across the world, employees are being subjected to increasing work demands and, as a result, work stress is on the rise. As we try to understand the root of the problem, we often end up blaming our boss.

Berry juice processing by-products could reduce the risk of cancer

Scientists at Kaunas University of Technology (KTU), Lithuania, are investigating the possibility of using berry pomace to increase the safety of meat products and to mitigate their negative effects on human health. According to the hypothesis proposed by the scientists, phytochemicals, i.e. the biologically active natural compounds found in berries, might mitigate the negative impact of additives used in meat products as well as naturally forming hazardous compounds during their processing, thus lowering the risk of cancer.

Exposure to blue light decreases blood pressure, reducing the risk of developing cardiovascular disease, a new study from the University of Surrey and Heinrich Heine University Dusseldorf in collaboration with Philips reports.

Pro-breastfeeding communities empower new moms

Social media can positively influence breastfeeding related attitudes, knowledge and behavior, according to a new study from the University of Alabama at Birmingham. Breastfeeding support groups on social media create a sense of community for new moms to share experiences and support each other in the breastfeeding practice and could be considered pillars of support for new moms.

Nested sequences: An indispensable mechanism for forming memories

Repetition is the best memorization method for neurons themselves. This is the principle behind what neurobiologists call sequence reactivations: During sleep, neurons in the hippocampus related to a task quickly activate in a precise order, which consolidates the memory of this task. Sequence reactivations are fundamental for long-term memorization and for exchanges between the hippocampus and the rest of the brain. These are only present at rest, so they appear after initial neuron activity, which implies that they "memorize" the order they should turn on in. But by which mechanism?

Addition of elotuzumab ups PFS in refractory multiple myeloma

(HealthDay)—For patients with multiple myeloma in whom treatment with lenalidomide and a proteasome inhibitor has failed, progression-free survival (PFS) is longer in those receiving the immunostimulatory monoclonal antibody elotuzumab in addition to pomalidomide and dexamethasone versus pomalidomide and dexamethasone alone, according to a study published in the Nov. 8 issue of the New England Journal of Medicine.

Breakthrough mouse model for diabetic kidney disease suggests a role for immune and inflammatory pathways

Scientists led by Duke-NUS Medical School have designed mice that successfully emulate a severe form of kidney damage in humans with diabetes, called diabetic nephropathy. Genetic analyses of the mice led to the surprising finding that expression of genes controlling immune and inflammatory responses may play a causal role in promoting kidney damage, and suggest these pathways might be promising targets for therapy.

Men focused on muscle building struggle with binge drinking and other problems

Young men who are overly preoccupied with building muscle have a significantly higher risk of depression, weekend binge drinking, and dieting that is not connected to obesity. They also have four times the probability of using legal and illegal supplements and anabolic steroids, a new study from the Norwegian University of Science and Technology (NTNU) and Harvard University has shown.

Allergy Chip: Multi-allergen test can even be done with dried blood

Using the Allergy Chip co-developed by MedUni Vienna, sensitisation to allergens can be detected early on. This normally requires a doctor taking a blood sample for subsequent analysis in a laboratory equipped with the Chip. In Austria, provision is excellent and there are enough laboratories offering this new test. Elsewhere, however, there are only a few per country – blood samples are therefore often protected as well as possible, carefully packed, chilled and air-freighted for analysis. That is a complicated and expensive process. A MedUni Vienna team led by lead investigator Rudolf Valenta from the Institute of Pathophysiologyand Allergy Research has now shown that this multi-allergen test works just as well with dried blood. Just a few drops of blood dried on a strip of Whatman paper (the extremely absorbent blotting paper most commonly used throughout the world) are enough.

The tobacco industry plays price games to make it even tougher to quit smoking

It is thought about two in three smokers want to kick their deadly habit, and with good reason – the same proportion of them are believed to die prematurely because of smoking. Around the world, the habit kills more than 6m people a year.

In tackling our physical inactivity pandemic, we risk ignoring those who need the most help

The longest living humans on Earth report engaging in daily physical activity as the secret of their longevity. For those who don't live such long lives, we know that spending too much time being inactive is a major cause of early death. Incredibly, it kills more people in the world than tobacco smoking each year.

A large nationally representative survey shows that the number of American adults and children using yoga and meditation has significantly increased over previous years and that use of chiropractic care has increased modestly for adults and held steady for children.

What do metastatic cancer cells have in common with sharks?

When animal predators search for sparsely distributed food, they maximize their chances of success by adopting a special movement pattern composed of many small steps interspersed with infrequent but long strides toward new hunting grounds. These so-called "Lévy walks" have been studied for several decades and observed in foraging mammals, birds, sharks, and even immune cells searching for infected cells. Researchers at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS) in South Korea, and several collaborating institutes in the U.S., the Netherlands, and Poland have reported that when cancer cells become invasive (metastatic), they start behaving in "predatory" ways.

NC reports the first death from Hepatitis A outbreak

North Carolina has reported its first death from Hepatitis A, a virus-borne infection that can be prevented by vaccination.

Rushing kids to specialize in one sport may not be best path to success

It may be tempting for parents or coaches to urge young children to specialize in one sport early on to help maximize their chance at making it to the big leagues, but that might not be the best path to success.

Study triggers change in WHO treatment guidelines for lymphatic filariasis

Researchers from Case Western Reserve University School of Medicine have shown that a single "cocktail" of three pill-based anti-parasite medications is significantly more effective at killing microscopic larval worms in people diagnosed with lymphatic filariasis, commonly known as elephantiasis, than other standard two-drug combinations previously used in the global effort to eliminate this infectious disease. A combination of all three drugs given simultaneously had never been tested until now. An estimated 120 million people in over 50 tropical and subtropical countries are infected with lymphatic filariasis and another 856 million people are at risk.

Brain learns to recognize familiar faces regardless of where they are in the visual field

A Dartmouth study finds that recognition of faces varies by where they appear in the visual field and this variability is reduced by learning familiar faces through social interactions. These biases are stable and idiosyncratic. More importantly, these biases are reduced for more familiar identities suggesting that the brain recognizes personally familiar faces more uniformly across the visual field. The findings suggest that repeated social interactions may tune populations of visual neurons in the face processing network to enable consistent and rapid recognition of familiar faces. The study was published in eNeuro, an open-access journal of the Society for Neuroscience.

Targeted radiation provides option for kids with difficult-to-treat liver cancer

Targeted tumor radiation provides a feasible treatment option for children with difficult-to-treat liver cancer, according to a new study published today in the journal Pediatric Blood and Cancer. The treatment, known as Transarterial Radioembolization with Yttrium-90 (TARE-Y90), shows promise for patients with liver cancer that is resistant to chemotherapy and cannot be surgically removed to help improve survival time, or to shrink tumor size to allow for surgical treatment or transplant.

Why modest goals are so appealing

Thanks to a quirk in the way our brain evaluates goals, people feel it's easier to achieve a small incremental goal than to maintain the status quo, when both goals are assessed in isolation. This is especially true if the context is seen as unfavourable.

Prostate cancer radiotherapy more precisely targeted with nuclear medicine imaging

Current standard imaging techniques for initial staging of prostate cancer often underestimate the extent of disease beyond the prostate. A study featured in The Journal of Nuclear Medicine's November issue demonstrates that prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) can pinpoint prostate cancer locations with superior accuracy. More accurate detection makes more precisely targeted treatment possible. Men with non-metastatic disease who chose radiotherapy could, therefore, improve their chances of a successful outcome with PSMA PET/CT imaging to more accurately define the areas targeted for irradiation.

Study demonstrates that long-term follow up in a trauma patient population is achievable

Dry conditions may have helped a new type of plant gain a foothold on Earth

In the dramatically changing conditions of ancient Earth, organisms had to evolve new strategies to keep up. From the mid-Oligocene, roughly 30 million years ago, to the mid-to-late Miocene, about 5 million years ago, carbon dioxide concentrations in the atmosphere fell by a roughly a third. This same period saw the emergence of a new form of photosynthesis in a subset of plants, the C4 pathway. Present in a subset of plants, the C4 pathway supplemented the earlier C3 photosynthetic pathway, meaning those species now reaped energy from the sun using two different strategies.

We now know how RNA molecules are organized in cells

Working with colleagues in the U.S., a team of Université de Montreal researchers has for the first time visualized how RNA molecules are organized in cells.

Researchers generate plants with enhanced drought resistance without penalizing growth

Extreme drought is one of the effects of climate change that is already occurring. This year, the decrease in rainfall and the abnormally hot temperatures in northern and eastern Europe have caused large losses in cereals and potato crops and in other horticultural species. Experts have long warned that to ensure food security, it is becoming necessary to use plant varieties that are productive in drought conditions. Now, a team led by the researcher at the Center for Research in Agricultural Genomics (CRAG) Ana Caño-Delgado has obtained plants with increased drought resistance by modifying the signaling of plant steroid hormones known as brassinosteroids. The study, published in the journal Nature Communications, is the first to find a strategy to increase hydric stress resistance without affecting overall plant growth.

Decline in shorebirds linked to climate change, experts warn

Climate change could be responsible for a substantial decline in populations of shorebirds, say researchers from the Milner Centre for Evolution at the University of Bath, following a study published in Science analysing population data over a period of 70 years.

Short stature in rainforest hunter-gatherers may be linked to cardiac adaptation

African and Asian rainforest hunter-gatherers share short stature, and now an international team of researchers has shown that this is an example of convergent adaptation that may also be linked to changes in cardiac development pathways.

Exploiting epigenetic variation for plant breeding

Epigenetic changes can bring about new traits without altering the sequence of genes. This may allow plants to respond quicker to changes in their environment. Plant biologists at the University of Zurich have now demonstrated that epigenetic variation is also subject to selection and can be inherited. This could expand the possibilities for crop breeding.

Embryos remember the chemicals that they encounter

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are cultivated over the course of development.

Unique study shows how bats manoeuvre

For the first time, researchers have succeeded in directly measuring the aerodynamics of flying animals as they manoeuvre in the air. Previously, the upstroke of the wings was considered relatively insignificant compared to the powerful downstroke but, in a new study, biologists at Lund University in Sweden have observed that it is on the upstroke of the wings that bats often turn.

Marine Protected Areas overlook a large fraction of biodiversity hotspots

Current marine protected areas (MPAs) leave almost three-quarters of ecologically and functionally important species unprotected, concludes a new performance assessment of the Finnish MPA network. Published in Frontiers in Marine Science, the study finds the MPAs were designated with little knowledge of local marine biodiversity—and that increasing existing networks by just 1% in ecologically most relevant areas could double conservation of the most important species. In addition to identifying areas of high conservation value, the methodology—which uses a unique new dataset of 140,000 samples—can also be used in ecosystem-based marine spatial planning and impact avoidance, including siting of wind energy infrastructure, aquaculture and other human activities.

Learning from gorillas to save killer whales

In 2018, the southern resident killer whale population in the Pacific Northwest's Salish Sea was at its lowest ever. The world watched in September as an orca named Scarlet, or J50, wasted away and died, leaving just 74 of her kind left. Some wondered if this was "What extinction looks like."

DNA fragments reveal the variety of species in rivers

Bits of genetic material in rivers make it possible to detect the organisms living in them – without having to collect these and examine them under the microscope. Researchers at Eawag, the ETH and the EPFL have now developed a computer model that, with the help of single DNA measurements, even simulates exactly where and how often the species are present in bodies of water.

Are organisms basically living machines?

New integrated analytical approach reveals molecules involved in disease

Technological advances have enabled scientists to obtain massive amounts of data on different information-carrying molecules in cells and tissues, such as DNA, proteins and various forms of RNA. However, to date, it has been difficult to perform integrated analyses of such information to further our knowledge on the molecules and processes involved in the development of particular diseases.

Bats versus dolphins – the ultimate battle of sonar systems

Active sensors are incorporated into a number of technologies, such as meteorology devices and self-driving cars, and use the echo from sound, radio or light waves to locate objects. But despite nearly a century of development, these active sensing technologies still fail to replicate the performance of sonars (sound waves) used in the biological world by dolphins and bats for echolocation.
