Keep your eclipse glasses to see the sun's 'freckles'

You don't have to wait on the next eclipse for another cool opportunity to look at the sun—our nearest star puts on quite the show of its own without the help of the moon. Heliophysics, the field of study devoted to the sun and its effects on space, is a science that can often be seen and appreciated from Earth. Some solar phenomenon manifest themselves with spectacular light shows while others are less conspicuous, rewarding careful observers who find themselves in the right place at the right time.

Technology news

Monitor tracks heart, respiratory rates of elderly living on their own

(Tech Xplore)—A scenario that is altogether contemporary in the broader cradle-to-grave journey: An elderly parent, over 65 years of age, functions independently, and lives alone. The fact is also that in his or her senior years there is the possibility of a medical emergency and the adult children would want to know.

Team efforts accelerate 3-D printing journey

With the development of additive manufacturing—often referred to as 3-D printing—engineers are limited only by their imagination—and the quality of the part that they can produce. By heating plastic or metal powders with lasers, scientists have already built cars, pedestrian bridges and even artificial jawbones layer by layer. This technology has the potential to transform manufacturing as engineers use titanium and other metal alloys to tap raw materials more efficiently, which in turn will reduce product costs and weight and shorten supply chains.

Low-cost wearables manufactured by hybrid 3-D printing

Human skin must flex and stretch to accommodate the body's every move. Anything worn tight on the body must also be able to flex around muscles and joints, which helps explain why synthetic fabrics like spandex are popular in active wear. Wearable electronic devices that aim to track and measure the body's movements must possess similar properties, yet integrating rigid electrical components on or within skin-mimicking matrix materials has proven to be challenging. Such components cannot stretch and dissipate forces like soft materials can, and this mismatch in flexibility concentrates stress at the junction between the hard and soft elements, frequently causing wearable devices to fail.

Researchers find shortened telomeres linked to dysfunction in Duchenne muscular dystrophy

Researchers from the Perelman School of Medicine at the University of Pennsylvania have made a discovery about muscular dystrophy disorders that suggest new possibilities for treatment. In a study published today online in Stem Cell Reports, researchers found that stem cells in the muscles of muscular dystrophy patients may, at an early age, lose their ability to regenerate new muscle, due to shortened telomeres.

Team finds that telomere length can have a direct correlation to heart failure in humans

Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the chromosome, protecting it from deterioration or fusion with adjacent chromosomes, much like the plastic tip at the end of a shoelace protects it from unraveling. While there is a length range for classifying a healthy telomere, researchers found, for the first time ever, that people with heart failure have shorter telomeres within the cells that make up the heart muscle (known as cardiomyocytes).

Human papillomavirus 16 infections may pose variable cancer risk

Human papillomavirus 16 accounts for about half of all cervical cancers, but researchers reporting September 7 in the journal Cell have found that not all infections are equal. An analysis of the HPV16 genome from 5,570 human cell and tissue samples revealed that the virus actually consists of thousands of unique genomes, such that infected women living in the same region often have different HPV16 sequences and variable risks to cancer. Women with precancer or cancer were most likely to have particular versions of the viral gene E7, which researchers are now interested in targeting.

'Weekend effect': Risk of dying higher if admitted to intensive care units at the weekend

A person's risk of dying is higher if they are admitted to the Intensive Care Unit (ICU) at the weekend compared to a weekday, according to a study involving 119 ICUs in Austria. Conversely, the risk of dying in the ICU on a weekend is lower than on a weekday, highlighting the complexity of the so-called 'weekend effect'. The study was published in the open access journal Critical Care.

Children exposed to chemicals in 9/11 'dust' show early signs of risk of heart disease

Sixteen years after the collapse of the World Trade Center towers sent a "cloud" of toxic debris across Lower Manhattan, children living nearby who likely breathed in the ash and fumes are showing early signs of risk for future heart disease.

Potentially lifesaving implantable cardioverter defibrillators underutilized in eligible patients

Fewer than 10% of people who experience sudden cardiac arrest (SCA) outside of a hospital survive. Reoccurrence rates after an initial event are high, which is why current Canadian Cardiovascular Society, as well as other international guidelines, strongly recommend the use of implantable cardioverter defibrillators (ICDs) in selected patients who survive cardiac arrest. Despite this recommendation, a new study published in the Canadian Journal of Cardiology reveals that real-life ICD utilization rates are lower than expected.

Tooth trouble: Many middle-aged adults report dental pain, embarrassment and poor prevention

The dental health of middle-aged Americans faces a lot of problems right now, and an uncertain future to come, according to new results from the University of Michigan National Poll on Healthy Aging.

Study shows oral food challenges are safe for diagnosing food allergies

The best way to find out if someone has a food allergy is through an oral food challenge (OFC) where the person is given a very small dose of the food by mouth under the supervision of a board-certified allergist to test for a severe reaction. A new study shows that OFCs are extremely safe, with very few people having a reaction of any kind.

Link established between a molecular driver of melanoma and novel therapeutic agent

Immunotherapy combination safe and 62 percent effective in metastatic melanoma patients

Immunotherapy is a promising approach in the treatment of metastatic melanoma, an aggressive and deadly form of skin cancer; but for most patients, immunotherapy drugs so far have failed to live up to their promise and provide little or no benefit. In a phase 1b clinical trial with 21 patients, researchers tested the safety and efficacy of combining the immunotherapy drug pembrolizumab with an oncolytic virus called T-VEC. The results suggest that this combination treatment, which had a 62% response rate, may work better than using either therapy on its own. The study appears September 7 in the journal Cell.

HCV treatment found safe and effective in individuals with kidney disease

A new study indicates that direct-acting antiviral therapy is safe and effective in patients with chronic kidney disease (CKD) and Hepatitis C virus (HCV) infection.

Career women optimistic about delayed childbearing despite lower fertility

Women who prioritize their careers value pregnancy planning and believe they have a good chance of conceiving late in life with the help of reproductive technology, even though fertility rates drop with age, according to a new Yale study. The findings suggest that career-focused women would benefit from guidance about age-related declines in fertility and the limits of reproductive technology, said the researchers.

Toxin-contaminated fish oil loses anti-cancer benefits

Weighing the health risks and rewards of eating fish and taking fish oil supplements is a tricky task. Fish oil, rich in healthy polyunsaturated fatty acids, can protect against certain types of cancer, but many types of fish are also contaminated by waterborne toxins. A new study by San Diego State University researchers found that toxin-contaminated fish oil loses much of its cancer-preventative properties.

Eating oily fish during pregnancy could prevent schizophrenia in the child, new study suggests

Researchers help uncover mechanism behind heart failure and mortality in sepsis

Of the nearly one million people in the United States who are affected by sepsis each year, almost one-fifth die. Cardiovascular complications account for approximately 80 percent of those deaths. The heart muscle, weakened by systemic inflammation, is unable to generate the energy it needs to contract, resulting in a severe decline in blood flow and oxygen delivery to tissues that ultimately leads to organ failure. Now, in new work, scientists at the Lewis Katz School of Medicine at Temple University (LKSOM), in collaboration with colleagues at Columbia University in New York, describe the mechanism underlying the loss of energy from heart dysfunction in sepsis, opening the way for the development of a new therapy that could save thousands of lives annually.

New dental imaging method uses squid ink to fish for gum disease

Squid ink might be a great ingredient to make black pasta, but it could also one day make getting checked for gum disease at the dentist less tedious and even painless. By combining squid ink with light and ultrasound, a team led by engineers at the University of California San Diego has developed a new dental imaging method to examine a patient's gums that is non-invasive, more comprehensive and more accurate than the state of the art.

Want your question answered quickly? Use gestures as well as words

When someone asks a question during a conversation, their conversation partner answers more quickly if the questioner also moves their hands or head to accompany their words. These are the findings of a study led by Judith Holler of the Max Planck Institute for Psycholinguistics and Radboud University Nijmegen in the Netherlands. The study is published in Springer's journal Psychonomic Bulletin & Review and focusses on how gestures influence language processing.

Life expectancy trends tied to 2016 voting choices

Ever since the unexpected results of the 2016 presidential election, political analysts have sought to understand what factors played into voters' decision making. Now, a new study by a Boston University School of Public Health (BUSPH) researcher shows how voting patterns correlated with the nation's growing geographic health divides, with Donald Trump winning more votes in counties that have seen lower gains in life expectancy.

Fifty-fifty split best for children of divorce

Preschool children in joint physical custody have less psychological symptoms than those who live mostly or only with one parent after a separation. In a new study of 3,656 children in Sweden, researchers from Uppsala University, Karolinska Institutet and the research institute CHESS show that 3-5-year-olds living alternately with their parents after a separation show less behavioural problems and psychological symptoms than those living mostly or only with one of the parents.

Antibody-biogel partnership can be stronger defense than previously thought, study proves

Strong molecular bonds between antibodies and biological gels, like mucus, aren't necessary to catch pathogens as was previously thought, according to new research from the University of North Carolina at Chapel Hill. In fact, rapid and weak interactions between antibodies and biogels are much better suited to locking down foreign invaders in the body's sticky first line of defense.

Link between positive emotions and health depends on culture

Positive emotions are often seen as critical aspects of healthy living, but new research suggests that the link between emotion and health outcomes may vary by cultural context. The findings, published in Psychological Science, a journal of the Association for Psychological Science, show that experiencing positive emotions is linked with better cardiovascular health in the US but not in Japan.

Nutrition has benefits for brain network organization, new research finds

Nutrition has been linked to cognitive performance, but researchers have not pinpointed what underlies the connection. A new study by University of Illinois researchers found that monounsaturated fatty acids - a class of nutrients found in olive oils, nuts and avocados - are linked to general intelligence, and that this relationship is driven by the correlation between MUFAs and the organization of the brain's attention network.

Biomarkers as predictive of sepsis as lengthy patient monitoring

Sepsis is a deadly and quick-moving medical condition, but its presence can be betrayed early on by the very immune responses that trigger it.

SNAP benefits aren't enough to afford a healthy diet

A new study from North Carolina State University and the Union of Concerned Scientists finds that the Supplemental Nutrition Assistance Program (SNAP), formerly known as Food Stamps, only covers 43-60 percent of what it costs to consume a diet consistent with federal dietary guidelines for what constitutes a healthy diet. The study highlights the challenges lower-income households face in trying to eat a healthy diet.

Double targeting ligands to identify and treat prostate cancer

Researchers have demonstrated a new, effective way to precisely identify and localize prostate cancer tumors while protecting healthy tissue and reducing side effects. The new approach utilizes a single molecule designed to bind two proteins with differing affinities in an effort to optimize specific tumor localization—prostate-specific membrane antigen (PSMA) and human serum albumin—thereby enhancing tumor localization for targeted alpha radionuclide therapy. The study is presented in the featured basic article of the September issue of The Journal of Nuclear Medicine.

What makes alcoholics drink? Research shows it's more complex than supposed

What makes alcoholics drink? New research has found that in both men and women with alcohol dependence, the major factor predicting the amount of drinking seems to be a question of immediate mood. They found that suffering from long-term mental health problems did not affect alcohol consumption, with one important exception: men with a history of depression had a different drinking pattern than men without a history of depression; surprisingly those men were drinking less often than men who were not depressed

Many ICU survivors depressed—study finds young and African-Americans at highest risk

Intensive care unit survivors, growing in number as clinicians and medical technology save more lives, are psychologically as well as medically fragile. The first study to examine antidepressant use and depressive symptoms after an ICU stay has found that even if prescribed antidepressants, a significant percentage—about a third—had symptoms of depression at the time of their initial visit to a clinic specially designed for ICU survivors. Young ICU survivors and African American ICU survivors were at the highest risk for depression.

Biology news

Handful of molecular machines run the biochemical oscillator that sets the timing of many bodily processes

Scientists have long known that circadian clocks—biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle—are present in all forms of life, including animals, plants, fungi and some types of bacteria. However, the molecular mechanisms that "run" these systems remain largely unknown.

Gut microbiota of larvae has an impact on mosquito's ability to transmit human pathogens

Researchers have demonstrated that differential bacterial exposure during the development of mosquito larvae (Aedes aegypti) can influence adult traits related to the transmission of arboviruses. This study represents an important step toward a more comprehensive understanding of how the environment shapes the risk of vector-borne disease.

Chromosome motor discovery supports DNA loop extrusion

It is one of the great mysteries in biology: How does a cell neatly distribute its replicated DNA between two daughter cells? For more than a century, we have known that DNA in the cell is comparable to a plate of spaghetti—a jumble of intermingled strands. When cells divide, they have to pack two metres of DNA into tidy little packages—chromosomes. This packing is induced by proteins called condensin, but scientists are split regarding the actual mechanism. One argument holds that the protein works like a hook, randomly grasping somewhere in the jumble of DNA and tying it all together. Another holds that the ring-shaped protein pulls the DNA inward to create a loop. In a new study reported in Science, researchers from TU Delft, Heidelberg and Columbia University give the oop-extrusion argument a significant boost, demonstrating that condensin does, indeed, have the putative motor function required for this dynamic.

In the wild, biodiversity's power surpasses what experiments predict

Hundreds of experiments have shown biodiversity fosters healthier, more productive ecosystems. But many experts doubted whether these experiments would hold up in the real world. A Smithsonian and University of Michigan study published Wednesday in the journal Nature offers a decisive answer: Biodiversity's power in the wild does not match that predicted by experiments—it surpasses it.

Bacteria found to produce compounds that activate sweet taste receptors in the sinuses allowing infections

(Phys.org)—A team of researchers affiliated with several institutions in the U.S. has found that a certain type of bacteria produces compounds that cause sweet taste receptors in the sinuses to activate—this in turn shuts off an immune response allowing the bacteria to thrive. In their paper published in the journal Science Signaling, the group describes their study of bacteria that cause chronic sinus infections and what they learned about them.

Cilia: 'The bouncer' of bacteria

Imagine a club scene—a bouncer at a velvet rope selects which individuals get into the club. This, explains Eva Kanso, a professor of mechanical engineering at USC Viterbi School of Engineering, is what cilia do in an organism. Kanso applied the analogy to explain her new paper, "Motile cilia create fluid-mechanical microhabitats for the active recruitment of the host microbiome," co-authored with researchers from the Pacific Biosciences Research Center at the University of Hawaii at Manoa and from Stanford, to explain the active role that cilia have in ensuring certain bacteria are kept out of an organism while other symbiotic bacteria are selectively permitted to enter.

The bacteria responsible for legionellosis modulates the host cell metabolism to its advantage

Scientists have shown that the bacterial pathogen Legionella pneumophila has developed a specific strategy to target host cell mitochondria, the organelles in charge of cellular bioenergetics. Their study provides information on how a pathogen manipulates the cellular metabolism to replicate intracellularly, and proposes a new concept of protection of host cells from Legionella-induced mitochondrial changes in order to fight infection.

Researchers break through the wall in bacterial membrane vesicle research

Many bacteria release membrane vesicles, which are nanoscale spheres consisting of a cellular membrane containing biomolecules. Membrane vesicles can transport DNA and proteins, and are involved in bacterial interactions. They have potential applications in nanotechnology and biomedicine, including cancer treatment. However, the formation of membrane vesicles by bacteria is currently not well understood. In particular, the release mechanism of membrane vesicles of Gram-positive bacteria, which have a very thick cell wall, has remained an enigma.

Researchers convert 80 percent of biomass into high-value products via new strategy

The three main components of non-edible plant matter can now be turned into high-value products in economically favorable yields. Using the concept of an integrated biorefinery, researchers showed how multiple products are created. The streams are similar to those used in a petroleum refinery. With the new approach, non-edible plant matter could become a promising alternative source of carbon. The resulting products—dissolving pulp, furfural, carbon foam and battery anodes—have established markets, reducing the risk for the first commercial plant.

Searching for the roots

What are the closest relatives of humans? What is the common origin of multicellular life? What is the source of disease-causing germs that can lead to devastating epidemics? Since the beginnings of modern research into evolution, questions as to the origin of organisms and their ancestor–descendent relationships have played a central role in the field of biology. However, most methods of analysis used have not been developed further for decades - unlike, for example, the genetic and molecular investigation techniques, which have been refined on an ongoing basis. The Genomic Microbiology working group at the Institute of General Microbiology at Kiel University (CAU) has now developed a new procedure which could revolutionise evolutionary biological research, and answer key questions in the history of how life developed. The CAU researchers Fernando Tria and Dr. Giddy Landan describe their universally-applicable bioinformatic method for the analysis of evolutionary lineage and ancestor–descendent relationships in the scientific journal Nature Ecology and Evolution.

Consequences of drought stress on biofuels

Plant-derived sustainable fuel sources could contribute to near-term U.S. energy security and independence. However, weather conditions could greatly affect crop yields. In this study, researchers examined the effect of weather on biofuel production by comparing switchgrass and corn stover harvested after a year of major drought and after 2 years of normal precipitation. They found that the plants produced more sugar, but the sugar changed during pretreatment and produced toxic compounds rather than the desired fuels.

Individuality drives collective behavior of schooling fish

New research sheds light on how "animal personalities" - inter-individual differences in animal behaviour - can drive the collective behaviour and functioning of animal groups such as schools of fish, including their cohesion, leadership, movement dynamics, and group performance. These research findings from the University of Konstanz, the Max Planck Institute of Ornithology and the University of Cambridge provide important new insights that could help explain and predict the emergence of complex collective behavioural patterns across social and ecological scales, with implications for conservation and fisheries and potentially creating bio-inspired robot swarms. It may even help us understand human society and team performance. The study is published in the 7 September 2017 issue of Current Biology.
