Nanodiscs catch misfolding proteins red-handed
Fri, 15 Dec 2017 13:51:47 EST
When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers have obtained a structural snapshot of these proteins when they are most toxic, detailing them down to the atomic level.
Complex, old-growth forests may protect some bird species in a warming climate
Fri, 15 Dec 2017 13:51:22 EST
Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found.
Genetic instructions from mom set the pattern for embryonic development
Fri, 15 Dec 2017 12:47:39 EST
A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.
Genetic study uncovers fungal sex secrets, which shed light on candidiasis
Fri, 15 Dec 2017 11:16:02 EST
A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study.
Committed to relatives: Hounds and wolves share their parasites
Fri, 15 Dec 2017 10:51:54 EST
Grey wolves, as all wild animals, are hosts to a variety of parasites. The presence of grey wolves in German forests has little influence on the parasite burden of hunting dogs, according to a new study.
Ancient feces reveal parasites described in earliest Greek medical texts

Earliest archaeological evidence of intestinal parasitic worms infecting the ancient inhabitants of Greece confirms descriptions found in writings associated with Hippocrates, the early physician and 'father of Western medicine.'
Nanoparticles as a solution against antibiotic resistance?
Fri, 15 Dec 2017 09:44:56 EST
Scientists have succeeded in developing an efficient method to treat mucoviscidosis. Crucial are nanoparticles that transport the antibiotics more efficiently to their destination. First of all, the active particles need to have a certain size to be able to reach the deeper airways and not to bounce off somewhere else before. Ultimately, they have to penetrate the thick layer of mucus on the airways as well as the lower layers of the bacteria biofilm.
First-of-its-kind chemical oscillator offers new level of molecular control
Thu, 14 Dec 2017 18:18:26 EST
Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors.
Horrific mating strategy appears to benefit both male and female redback spiders
Thu, 14 Dec 2017 16:40:38 EST
A mating strategy among redback spiders where males seek out immature females appears to benefit both sexes, a new study has found.
MRSA risk at northeast Ohio beaches
Thu, 14 Dec 2017 15:33:59 EST
A study conducted in 2015 shows a higher-than-expected prevalence of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) at beaches around Lake Erie.
Valley fever cases see major spike in November, experts say
Thu, 14 Dec 2017 15:33:56 EST
An uptick in reported cases of Valley fever indicates a likely sharp increase in infections next year. At the same time, federal clearance for a rapid assay test developed with assistance from the University of Arizona should help reduce delays in diagnosing the respiratory fungal disease caused by spores found in area soils.
Northeast farmers weigh warming climate, drenched fields
Thu, 14 Dec 2017 15:33:44 EST
Farmers in the Northeast are adapting to longer growing seasons and warming climate conditions -- but they may face spring-planting whiplash as they confront fields increasingly saturated with rain, according to a research paper.
Conserving the forests
Thu, 14 Dec 2017 15:33:39 EST
Certification programs are being reevaluated as options for sustaining tropical forests, explain scientists.
All politics -- and cannabis marketing -- are local
Thu, 14 Dec 2017 15:33:34 EST
California's legal cannabis market, opening for business on Jan. 1, is expected to quickly grow to be the largest in the nation and worth more than $5 billion a year. County voting on Proposition 64 that led the state here -- to legalizing sales for recreational use -- can offer insight into how medical marijuana dispensaries will now market themselves.
Bioluminescent worm found to have iron superpowers
Thu, 14 Dec 2017 15:33:32 EST
Researchers have made a discovery with potential human health impacts in a parchment tubeworm, found to have ferritin with the fastest catalytic performance ever described.
Mechanism identified of impaired dendritic cell function that weakens response to cancer
Thu, 14 Dec 2017 15:33:27 EST
The mechanism implicated in the defective function of tumor-associated dendritic cells (DCs), a specialized type of immune cells that expose the antigens on their surface to activate the T cells, has now been revealed by researchers.
Hope for one of the world's rarest primates: First census of Zanzibar Red Colobus monkey
Thu, 14 Dec 2017 15:33:22 EST
A team of scientists recently completed the first-ever range-wide population census of the Zanzibar red colobus monkey (Piliocolobus kirkii) an endangered primate found only on the Zanzibar archipelago off the coast of East Africa.
