(Press-News.org) A team of scientists from the Universidad de La República, Uruguay discovered three native to northern Argentina new species of the engaging spider group of the tarantulas. The study describing the newly found tarantulas was published in the open access journal ZooKeys.
The often hairy and very large spiders known as tarantulas are one of the most famous arachnid groups. Despite their ill fame as vicious killers most tarantulas are harmless to humans. Most tarantulas long lifespans, females can live between 15 and 30 years, which makes them a preferred pet for spider lovers around the world.
The subfamily Theraphosinae to which the three new species belong is a large group of tarantulas distributed exclusively in the New World, whose greatest diversity is found in South America. The 3 new additions are native to the northern parts of Argentina, a region which inspired their names.
Melloleitaoina mutquina, for example has its name derived from the specific epithet mutquina, a noun which means place or thing to smell in Quichua language. This poetic name refers to the locality of Mutquín, where this species is distributed and denotes the aroma of the flora of the region that emerges after rain, perfuming the village of aromatic herbs.
Similarly, M. uru was inspired an ancient legend Quichua, from the northern limit of Argentina, about the Inca princess Uru, who because of her whims and bad government was transformed by the gods into a spider and forced to endlessly work weaving. Lastly, the third new species M. yupanqui, was named to honor to the most important Argentine musician of folklore Atahualpa Yupanqui, pseudonym of Héctor Roberto Chavero Aramburu.

A hydrogel that knows when to go
2014-05-07
HOUSTON – (May 7, 2014) – Rice University bioengineers have created a hydrogel that instantly turns from liquid to semisolid at close to body temperature – and then degrades at precisely the right pace.
The gel shows potential as a bioscaffold to support the regrowth of bone and other three-dimensional tissues in a patient's body using the patient's own cells to seed the process.
The hydrogel created in the lab of Rice bioengineer Antonios Mikos is a liquid at room temperature but, when injected into a patient, becomes a gel that would fill and stabilize a space while ...
NASA sees system 91B making landfall in southwestern India
2014-05-07
A tropical low was affecting southern India and Sri Lanka on May 6 at 0809 UTC when the Tropical Rainfall Measuring Mission satellite called TRMM flew above it. By May 7, System 91B moved over southwestern India and became less organized.
TRMM's Precipitation Radar revealed that rain was falling at a rate of 66 mm (2.6 inches) per hour in the stormy area south of India (5.2 north latitude and 77.1 east longitude). TRMM PR saw the tallest thunderstorm towers over Sri Lanka where heights were pushing to altitudes above 13 km (8 miles).
On May 7 at 12:30 UTC/8:30 a.m. ...
Perceived age and weight discrimination worse for health than perceived racism and sexism
2014-05-07
TALLAHASSEE, Fla. — Perceived age and weight discrimination, more than perceived race and sex discrimination, are linked to worse health in older adults, according to new research from the Florida State University College of Medicine.
The findings are part of a study measuring changes in health over a four-year period and published in the American Journal of Geriatric Psychiatry.
"Our previous research showed that perceived discrimination based on body weight was associated with risk of obesity. We wanted to see whether this association extended to other health indicators ...
Phytoplankton and zooplankton biomass will decrease 6 percent and 11 percent due to climate change
2014-05-07
Sea surface temperature is expected to increase 2 ºC on average globally by 2080-2100. Some of the consequences of this increase include changes in ocean circulation and higher water column stratification, thus affecting the nutrient availability for the growth of marine phytoplankton.
The research team led by Azti-Tecnalia points out the effects to primary production (phytoplankton mass produced annually by photosynthetic single-celled organisms that are suspended in the ocean), and to secondary production (zooplankton biomass, made up of small animal organisms that ...
National coordination needed to advance convergent research
2014-05-07
WASHINGTON -- Convergent research – which crosses disciplinary boundaries, integrating tools and knowledge from the life sciences, physical sciences, engineering, and other fields -- could spur innovation and help tackle societal challenges, but greater national coordination is needed, says a new report from the National Research Council. Convergent science still faces hurdles and requires a culture shift for research institutions, which have traditionally organized research around separate disciplines.
Convergent science also relies on forming a web of partnerships ...
Yellowstone geyser eruptions influenced more by internal processes
2014-05-07
The intervals between geyser eruptions depend on a delicate balance of underground factors, such as heat and water supply, and interactions with surrounding geysers. Some geysers are highly predictable, with intervals between eruptions (IBEs) varying only slightly. The predictability of these geysers offer earth scientists a unique opportunity to investigate what may influence their eruptive activity, and to apply that information to rare and unpredictable types of eruptions, such as those from volcanoes.
Dr. Shaul Hurwitz took advantage of a decade of eruption data—spanning ...
Breakthrough NIH study will have major implications for treating pediatric UTIs
2014-05-07
DETROIT — A major new pediatric research study led by a Wayne State University researcher, funded by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health (NIH) and published this week in the New England Journal of Medicine (NEJM), has "major implications" for the treatment of urinary tract infections (UTIs) in millions of American children.
The largest study of its kind in the world, it provides convincing evidence that children with a common urinary-tract abnormality known as "vesicoureteral reflux" (or "VUR") experience ...
Racism -- not what the doctor ordered
2014-05-07
The world first review explored interpersonal racism perpetrated by healthcare providers, a key driver of racial disparities in health. Interpersonal racism refers to racist interactions between individuals, rather than internalised or systemic or institutional racism.
Researchers Ms Mandy Truong and Dr Naomi Priest from the University of Melbourne and Professor Yin Paradies from Deakin University, reviewed 37 studies published between 1995 and 2012 of racism among healthcare providers.
The review assessed attitudes towards race held by physicians, nurses and allied ...
Matching the expertise of perfumers to create new scents
2014-05-07
From jasmine to sandalwood, the alluring scents of the most luxurious perfumes might seem more art than science, but a new way to analyze them breaks from the tradition of relying only on experts' sense of smell to blend fragrances. Scientists report that they have developed a model that can help perfumers predict how various combinations of chemicals will smell. The study appears in the ACS journal Industrial & Engineering Chemistry Research.
Miguel A. Teixeira and colleagues from LSRE laboratory in Portugal explain that the design of new fragrances for the perfume industry ...
Scientists link honeybees' changing roles throughout their lives to brain chemistry
2014-05-07
Scientists have been linking an increasing range of behaviors and inclinations from monogamy to addiction to animals', including humans', underlying biology. To that growing list, they're adding division of labor — at least in killer bees. A report published in ACS' Journal of Proteome Research presents new data that link the amounts of certain neuropeptides in these notorious bees' brains with their jobs inside and outside the hive.
Mario Sergio Palma and colleagues explain that dividing tasks among individuals in a group is a key development in social behavior among ...
