Researchers have cracked the cellular code on protein folding, offering hope for new therapeutic avenues for many diseases      (via sciencedaily.com)     Original source 

While we often think of diseases as caused by foreign bodies -- bacteria or viruses -- there are hundreds of diseases affecting humans that result from errors in cellular production of its proteins. A team of researchers recently leveraged the power of cutting-edge technology, including an innovative technique called glycoproteomics, to unlock the carbohydrate-based code that governs how certain classes of proteins form themselves into the complex shapes necessary to keep us healthy.

New technique efficiently offers insight into gene regulation      (via sciencedaily.com)     Original source 

Researchers have developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other.

Unlocking the secret strength of marine mussels      (via sciencedaily.com)     Original source 

How do you create strong, yet quick-release connections between living and non-living tissues? This is a question that continues to puzzle bioengineers who aim to create materials that bond together for advanced biomedical applications. Looking to nature for inspiration, this research zeroed in on the marine mussel byssus, a fibrous holdfast, which these bivalve mollusks use to anchor themselves in seashore habitats.

'Bone biographies' reveal lives of medieval England's common people -- and illuminate early benefits system      (via sciencedaily.com)     Original source 

Researchers give medieval Cambridge residents the 'Richard III treatment' to reveal hard-knock lives of those in the city during its famous university's early years. Study of over 400 remains from a hospital cemetery shows spectrum of medieval poverty, and suggests that some of Cambridge University's earliest scholars ended up in penury.

Decoding past climates through dripstones      (via sciencedaily.com)     Original source 

A recent study demonstrates how dripstones can be crucial for reconstructing past climates. The new approach can provide a detailed picture of the climate around early human occupations in South Africa.

Dishing the dirt on human evolution: Why scientific techniques matter in archaeology      (via sciencedaily.com)     Original source 

Scientists should seek answers hidden in the dirt using proven and state-of-the-art archaeological science techniques to support new discoveries about human evolution following recent controversies at a cave site in Africa, says a group of international experts. Their recommendations follow claims published in June of this year that Homo naledi --a small-brained human species -- buried their dead in Rising Star Cave, South Africa, between 335,000 and 241,000 years ago, and may also have decorated the cave walls with engravings.

Armed to the hilt: Study solves mystery behind bacteria's extensive weaponry      (via sciencedaily.com)     Original source 

A new study tackles the mystery of why bacteria often carry diverse ranges of weapons. The findings show that different weapons are best suited to different competition scenarios. Short-range weapons help bacteria to invade established communities; long-range weapons are useful once established.

Study of ancient British oral microbiomes reveals shift following Black Death      (via sciencedaily.com)     Original source 

The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.

Clever dosage control mechanism of biallelic genes      (via sciencedaily.com)     Original source 

Researchers have uncovered a mechanism that safeguards the biallelic expression of haploinsufficient genes, shedding light on the importance of having two copies of each chromosome. A study identified the epigenetic regulator MSL2 an 'anti-monoallelic' factor that maintains biallelic gene dosage. This discovery not only reveals a communication system between parental alleles but also points to potential therapeutic strategies for diseases associated with haploinsufficient genes.

Researchers decipher enzyme scissors of intestinal microbes      (via sciencedaily.com)     Original source 

Fruit and vegetables contain a variety of plant natural products such as flavonoids, which give fruits their colour and are said to have health-promoting properties. Most plant natural products occur in nature as glycosides, i.e. chemical compounds with sugars. In order for humans to absorb the healthy plant natural products, the sugar must be split off in the intestine. Microorganisms in the intestinal flora help to speed up the process. So-called C-glycosides, i.e. plant natural products with a carbon-based bond to a sugar, would even be practically indigestible without the intestinal microbes (e.g. nothofagin in rooibos tea).

Releasing brakes on biocatalysis      (via sciencedaily.com)     Original source 

Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.

Tracing the evolution of the 'little brain'      (via sciencedaily.com)     Original source 

The evolution of higher cognitive functions in humans has so far mostly been linked to the expansion of the neocortex. Researchers are increasingly realizing, however, that the 'little brain' or cerebellum also expanded during evolution and probably contributes to the capacities unique to humans. A research team has now generated comprehensive genetic maps of the development of cells in the cerebella of human, mouse and opossum. Comparisons of these maps reveal both ancestral and species-specific cellular and molecular characteristics of cerebellum development.

Was 'witchcraft' in the Devil's Church in Koli based on acoustic resonance? The crevice cave has a unique soundscape      (via sciencedaily.com)     Original source 

The national park of Koli in eastern Finland is home to a famous, 34-metre-long crevice cave known as Pirunkirkko, or Devil's Church in English. A new study investigates the acoustics of the Devil's Church and explores whether the acoustic properties of the cave could explain the beliefs associated with it, and why it was chosen as a place for activities and rituals involving sound.
