Immunity connects gut bacteria and aging

Over the years, researchers have learned that the different populations of bacteria that inhabit the gut have significant effects on body functions, including the immune system. The populations of gut bacteria are sometimes called "commensal," and exist in virtually all animals living under a certain functional balance. When this balance is disrupted—for example, because of disease or medication—it gives rise to a condition known as "commensal dysbiosis," which is associated with a number of pathologies and even a decreased lifespan. Despite this knowledge, little is known about how, exactly, the gut bacteria affect general health and vice versa.

2 more kids sickened with adenovirus that has killed 10 children at New Jersey facility

Two more children at a Wanaque medical facility were diagnosed over the weekend with adenovirus, which has killed 10 medically fragile children at the facility since the outbreak began in late September, health officials reported.

Combination gene therapy more effective in cartilage preservation in osteoarthritis

A combinatorial gene therapy approach- one designed to inhibit inflammation and one targeting protection against cartilage degeneration—was shown to preserve articular cartilage better than each approach alone in animal models of both moderate and severe post-traumatic osteoarthritis. The therapeutic strategy included combined delivery of helper-dependent adenoviruses expressing interleukin-1 receptor antagonist (IL-1Ra) to block inflammation and PRG4 (lubricin) to promote pro-anabolic cartilage genes and decrease expression of catabolic genes, as reported in an article published in Human Gene Therapy.

Failure to discontinue medications can contribute to inappropriate prescribing

The continuation of drugs that are not intended to be taken indefinitely is a substantial and common problem that could contribute to over-medication, particularly in the elderly.

WHO official predicts 6 more months battling Ebola in Congo

The emergencies chief for the World Health Organization predicted Tuesday that Congo's Ebola outbreak will last at least another six months, saying that informal health facilities have become "major drivers" of the current, deadly transmission.

Experimental therapy could repair mutations that cause genetic diseases

A new technology that relies on a moth-infecting virus and nanomagnets could be used to edit defective genes that give rise to diseases like sickle cell, muscular dystrophy and cystic fibrosis.

Climate change damaging male fertility

Climate change could pose a threat to male fertility—according to new research from the University of East Anglia.

Neural nets supplant marker genes in analyzing single cell RNA sequencing

Computer scientists at Carnegie Mellon University say neural networks and supervised machine learning techniques can efficiently characterize cells that have been studied using single cell RNA-sequencing (scRNA-seq). This finding could help researchers identify new cell subtypes and differentiate between healthy and diseased cells.

Pulling the genome apart: Chromosome segregation during mitosis explained

When a cell divides—a process known as mitosis—its chromosomes need to be separated and evenly distributed into the newly created daughter cells. Although this is known to be extremely complicated and to feature a range of cellular components, many of its details remain unclear, which has hampered efforts to develop treatments for when mitosis goes awry.

Color vision variation in guppies influences female mate preference

A variety of animals have male-specific ornament traits and these ornaments are favored by female choice. Which male traits are preferred by females often varies among females. Genetic mechanisms that create and maintain variations in female preference has been one of the central questions in evolutionary ecology.

House sparrow status signalling theory no longer flies

The size of a male house sparrow's bib has long been associated with the bird's fighting abilities and status within the flock. But an international team of researchers has shown there is little evidence to support it.

Amazon turtle populations recovering well thanks to local action

The historically over-exploited Giant South American Turtle is making a significant comeback on river beaches in the Brazilian Amazon thanks to local protection efforts, say researchers at the University of East Anglia.

Scientists uncover crucial biological circuits that regulate lipids and their role in overall health

Tiny microscopic worms, invisible to the naked eye, are helping scientists to better understand an extraordinarily complex biological pathway that connects fat to overall health and aging in humans.

'Scaring' soybeans into defensive mode yields better plants a generation later

By temporarily silencing the expression of a critical gene, researchers fooled soybean plants into sensing they were under siege, encountering a wide range of stresses. Then, after selectively cross breeding those plants with the original stock, the progeny "remember" the stress-induced responses to become more vigorous, resilient and productive plants, according to a team of researchers.

DNA structure impacts rate and accuracy of DNA synthesis

The speed and error rate of DNA synthesis is influenced by the three-dimensional structure of the DNA. Using "third-generation" genome-wide DNA sequencing data, a team of researchers from Penn State and the Czech Academy of Sciences showed that sequences with the potential to form unusual DNA conformations, which are frequently associated with cancer and neurological diseases, can in fact slow down or speed up the DNA synthesis process and cause more or fewer sequencing errors. An article describing the study appears online in the journal Genome Research.

Visualizing 'unfurling' microtubule growth

Living cells depend absolutely on tubulin, a protein that forms hollow tube-like polymers, called microtubules, that form scaffolding for moving materials inside the cell. Tubulin-based microtubule scaffolding allows cells to move, keeps things in place or moves them around. When cells divide, microtubule fibers pull the chromosomes apart into new cells. Cells with defects in tubulin polymerization die.

The first cave-dwelling centipede from southern China

Chinese scientists recorded the first cave-dwelling centipede known so far from southern China. To the amazement of the team, the specimens collected during a survey in the Gaofeng village, Guizhou Province, did not only represent a species that had been successfully hiding away from biologists in the subterranean darkness, but it also turned out to be the very first amongst the order of stone centipedes to be discovered underground in the country.

Business as usual for Antarctic krill despite ocean acidification

While previous studies indicate some life stages of Antarctic krill may be vulnerable to ocean acidification, the research published in the Nature journal Communications Biology found that adult krill were largely unaffected by ocean acidification levels predicted within the next 100-300 years.

Imperiled, some freshwater mussels endure. How?

Freshwater mussels are among the most imperiled animals in North America, yet some colonies have managed to persevere despite habitat loss, pollution and other threats.

A chip with blood vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

More flowers around apple orchards can yield higher harvest

Apple growers should increase the amount of flowers around their apple orchards if they want to increase their harvest. A new study by researchers from Stockholm University, among others, shows that more pollinators, such as bees and flower flies, are attracted to orchards with flowers – which increase the chance for pollination.
