The brain is 'programmed' for learning from people we like

Science Daily: Pharmacology News

Our brains are 'programmed' to learn more from people we like -- and less from those we dislike. This has been shown by researchers in cognitive neuroscience in a series of experiments.

Understanding Parrot Fever (Psittacosis): A Rare Infectious Disease

Gideon

Parrot Fever, or psittacosis, mostly affects birds but the disease can spread to humans. This bacterial infection is also a Category B agent of bioterror, according to the US CDC. That’s because it is a zoonotic disease that could be aerosolized and spread far and wide. As a result, public health agencies need to keep an eye on parrot fever outbreaks.

Reforestation programs could threaten vast area of tropical grasslands

Science Daily: Pharmacology News

New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.

Evidence of geothermal activity within icy dwarf planets

Science Daily: Pharmacology News

A team found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or even hot geochemistry in their rocky cores, which is markedly different than the signature of methane from a comet.

Ancient retroviruses played a key role in the evolution of vertebrate brains

Science Daily: Pharmacology News

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred sepa

Discovery of new Li ion conductor unlocks new direction for sustainable batteries

Science Daily: Pharmacology News

Researchers have discovered a solid material that rapidly conducts lithium ions. Consisting of non-toxic earth-abundant elements, the new material has high enough Li ion conductivity to replace the liquid electrolytes in current Li ion battery technology, improving safety and energy capacity. The research team have synthesized the material in the laboratory, determined its structure and demonstrated it in a battery cell.

Root microbes may be the secret to a better tasting cup of tea

Science Daily: Pharmacology News

You'd think the complex flavor in a quality cup of tea would depend mainly on the tea varieties used to make it. But a new study shows that the making of a delicious cup of tea depends on another key ingredient: the collection of microbes found on tea roots. By altering that assemblage, the authors showed that they could make good-quality tea even better.

A star like a Matryoshka doll: New theory for gravastars

Science Daily: Pharmacology News

If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein's theory of general relativity, according to which gravitational stars could be structured like a Russian matryoshka doll, with one gravastar located inside another.

Searching for clues in the history book of the ocean

Science Daily: Pharmacology News

New research has shown that the tropical subsurface ocean gained oxygen during the Paleocene-Eocene Thermal Maximum (commonly referred to as PETM). During this short-lived interval of time in Earth s history that occurred 56 million years ago the average temperatures rose by up to six degrees within a few thousand years.
