Viruses that can help 'dial up' carbon capture in the sea      (via sciencedaily.com)     Original source 

Armed with a catalog of hundreds of thousands of DNA and RNA virus species in the world's oceans, scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane's escape from thawing Arctic soil.

Giant Antarctic sea spiders reproductive mystery solved      (via sciencedaily.com)     Original source 

Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.

Mystery solved: The oldest fossil reptile from the alps is an historical forgery      (via sciencedaily.com)     Original source 

Palaeontological analysis shows that a renowned fossil thought to show soft tissue preservation is in fact just paint. The fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is utilized in future.

Beyond peak season: Bacteria in the Arctic seabed are active all year round      (via sciencedaily.com)     Original source 

Researchers studied the composition and function of bacteria in the seabed off Svalbard, during alternating periods of polar night and midnight sun. To do this, they specially developed a sampling device, the Ellrott grab. In contrast with bacterial communities in the overlying water, the sediment bacteria hardly change with the seasons. This is probably due to the fact that in the seabed some hard-to-digest foods are available all year round.

Reforestation programs could threaten vast area of tropical grasslands      (via sciencedaily.com)     Original source 

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.

Researchers shed light on river resiliency to flooding      (via sciencedaily.com)     Original source 

Researchers have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. Increased understanding of rivers' resiliency is important to maintaining healthy rivers, as human actions can affect flood regimes and change the conditions in rivers for other aquatic life that may rely on algae and plants as a food source.

When it comes to bad breath, some bacterial interactions really stink      (via sciencedaily.com)     Original source 

Researchers found that the oral bacterium Streptococcus gordonii activates another bacterial species, Fusobacterium nucleatum, to produce large quantities of methyl mercaptan, a compound responsible for bad breath. Disrupting this interaction could therefore help treat halitosis, and possibly also help prevent the development of more serious tooth and gum disease.

Asexual propagation of crop plants gets closer      (via sciencedaily.com)     Original source 

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered without fertilization, as researchers have shown. Their findings open up new avenues for the asexual propagation of crop plants.

Root microbes may be the secret to a better tasting cup of tea      (via sciencedaily.com)     Original source 

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.

Ancient retroviruses played a key role in the evolution of vertebrate brains      (via sciencedaily.com)     Original source 

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 separately in each of these groups.

A lighthouse in the Gobi desert      (via sciencedaily.com)     Original source 

A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
