Experimental antibody 'cocktail' protects animals from three deadly Ebola viruses

1 week ago from Science Daily

Scientists have developed a combination of monoclonal antibodies that protected animals from all three Ebola viruses that cause human disease. The antibody 'cocktail,' called MBP134, is the first experimental treatment...

Fish farmers of the Caribbean

1 week ago from Science Daily

There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will...

Decades-old question about protein found in Alzheimer's brain plaques

1 week ago from Science Daily

Alzheimer's-affected brains are riddled with so-called amyloid plaques: protein aggregates consisting mainly of amyloid-beta. However, this amyloid-beta is a fragment produced from a precursor protein whose normal function has remained...

Blue Jackets' Sergei Bobrovsky out vs. Predators following 'incident'

1 week ago from UPI

Columbus goalie Sergei Bobrovsky will not be with the Blue Jackets for Thursday night's game against the Nashville Predators, the team announced in a statement.

Giving Cas9 an 'on' switch for better control of CRISPR gene editing

1 week ago from Science Daily

Scientists have created an 'on' switch for CRISPR-Cas9 that allows it to be turned on in select cells only, specifically those that have a particular protein-cutting enzyme, or protease. Viruses...

Far-ranging fin whales find year-round residence in Gulf of California

1 week ago from Science Daily

Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round -- an unusual circumstance...

Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round—an unusual circumstance for a...

Alzheimer’s protein may stabilize activity in the brain 

1 week ago from C&EN

Researchers determine that a nonpathogenic form of amyloid precursor protein binds to a brain receptor to balance electrical activity

Response to Comment on "Impacts of species richness on productivity in a large-scale subtropical forest experiment"

1 week ago from Science NOW

Yang et al. have raised criticism that the results reported by us would not be relevant for natural forests. We argue that productivity is positively related to species richness also...

Secreted amyloid-{beta} precursor protein functions as a GABABR1a ligand to modulate synaptic transmission

1 week ago from Science NOW

Amyloid-β precursor protein (APP) is central to the pathogenesis of Alzheimer’s disease, yet its physiological function remains unresolved. Accumulating evidence suggests that APP has a synaptic function mediated by an...

An evolutionary perspective on immunometabolism

1 week ago from Science NOW

Metabolism is at the core of all biological functions. Anabolic metabolism uses building blocks that are either derived from nutrients or synthesized de novo to produce the biological infrastructure, whereas...

Cell-autonomous clock of astrocytes drives circadian behavior in mammals

1 week ago from Science NOW

Circadian (~24-hour) rhythms depend on intracellular transcription-translation negative feedback loops (TTFLs). How these self-sustained cellular clocks achieve multicellular integration and thereby direct daily rhythms of behavior in animals is largely...

Invertible promoters mediate bacterial phase variation, antibiotic resistance, and host adaptation in the gut

1 week ago from Science NOW

Phase variation, the reversible alternation between genetic states, enables infection by pathogens and colonization by commensals. However, the diversity of phase variation remains underexplored. We developed the PhaseFinder algorithm to...

Emergence of preconfigured and plastic time-compressed sequences in early postnatal development

1 week ago from Science NOW

When and how hippocampal neuronal ensembles first organize to support encoding and consolidation of memory episodes, a critical cognitive function of the brain, are unknown. We recorded electrophysiological activity from...

Problem-solving males become more attractive to female budgerigars

1 week ago from Science NOW

Darwin proposed that mate choice might contribute to the evolution of cognitive abilities. An open question is whether observing the cognitive skills of an individual makes it more attractive as...

Cap-specific terminal N6-methylation of RNA by an RNA polymerase II-associated methyltransferase

1 week ago from Science NOW

N6-methyladenosine (m6A), a major modification of messenger RNAs (mRNAs), plays critical roles in RNA metabolism and function. In addition to the internal m6A, N6, 2'-O-dimethyladenosine (m6Am) is present at the...

Mothers use sex pheromones to veil eggs, preventing cannibalism

1 week ago from Physorg

Species that lay eggs but don't actively keep watch over them often protect their precious eggs from predators by laying them in communal groups or by fortifying them with toxins....

Researchers see a wealth of potential for aquaculture in the Caribbean

1 week ago from Physorg

There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will...

Intelligent males may make female birds swoon: study

1 week ago from Physorg

Male birds are often the ones with the most vibrant feathers, or the most elaborate songs, but researchers said Thursday that what female birds could really appreciate is a male...

Poison toilet paper reveals how termites help rainforests resist drought

1 week ago from Sciencenews.org

Novel use of poisoned toilet paper rolls and teabags led to discovery that termites help tropical forests resist droughts.

Coke-funded group swayed China's obesity efforts, researchers say
