Mysterious larvae discovered in Panama’s two oceans

These ghostly larvae float freely in seawater, while their parents live on the sea floor and usually go undetected

Under the microscope, sea water reveals the larval stages of little-known marine creatures called phoronids (horseshoe worms), but finding their parents is another story. Although such fanciful larvae caught the eye of scientists studying plankton—the tiny, drifting plants and animals in the world’s oceans—as long ago as the 1800s, there are only about 15 species of phoronids known worldwide, based on adult specimens. A study of phoronid larvae published this week by scientists at the Smithsonian Tropical Research Institute (STRI) in Panama has detected eight potentially new species.

Ancient ritual bundle contained multiple psychotropic plants

the co-occurrence of harmine and DMT -which are the primary ingredients of ayahuasca- in the pouch suggests the use of this beverage as one of the drugs in the shaman's kit

A thousand years ago, Native Americans in South America used multiple psychotropic plants -- possibly simultaneously -- to induce hallucinations and altered consciousness, according to an international team of anthropologists.

Parasitoid wasps may turn spiders into zombies by hacking their internal code

New observations of Costa Rican spiders demonstrate several previously unappreciated patterns that suggest that the wasp larvae use ecdysone

Setting off a startling chain of events, a parasitoid wasp can force a spider to weave a special web to suspend the wasp pupa just before it finishes killing its spider host. William Eberhard, staff scientist emeritus at the Smithsonian Tropical Research Institute and Marcelo Gonzaga at the Universidade Federal de Uberlândia in Brazil have assembled wide-ranging evidence that 'zombification' involves hacking existing web-spinning mechanisms by hijacking the spider's own molting hormone, ecdysone.

Picos de Europa National Park has given its name to a new species of perennial bromegrass, discovered in Spain. Bromus picoeuropeanus belongs to a rather underrepresented on the Iberian Peninsula perennial group within the grass genus Bromus, with the new species being just the fourth of all recognised wild species living in the Iberian territory.

New liquid biopsy technique assess melanoma progression

This is very important in melanoma, since it is an aggressive tumour type that metastasizes in a large number of patients

When the surgeon surgically removes a melanoma, some patients are said to be 'cancer-free' and they do not get additional treatment. However, should the fluid obtained in the drainage implanted after surgery be tested using the liquid biopsy technique rather than be disposed of as medical waste, the test might predict the high or low risk of cancer recurrence.

Argentinian researchers discover an extraordinary 220 million year old animal cemetery in San Juan. It is a surprising accumulation of fossils that would belong to dinosaurs, giant crocodiles and mammalian ancestors. In this "bed of bones", there are skulls and dismembered parts of, at least, seven or eight individuals, although there could be many more.

Mechanism to form influenza A virus discovered

The study of the team of Maria João Amorim reveals that the selection of the genetic material is made in viral-induced compartments called viral inclusions

The influenza A virus is known to form new strains every year. These strains are the result of small variations occurring at the level of the genome, which cause the virus to become different and no longer recognized by the immune system. A new study by Maria João Amorim's team, from the Gulbenkian Institute of Science, now reveals where the genomes of the influenza A virus are assembled inside infected cells. The results will be published this week in the journal Nature Communications* and may contribute to therapies that prevent or combate new strains of influenza viruses.

Microbes may fight the epidemic driving some frog species to extinction

A compound produced by Panamanian frog skin bacteria could help resist fungal infections in amphibians and humans worldwide

In the past few decades, a lethal disease caused by the chytrid fungus has decimated amphibian populations worldwide, driving some species to extinction. This is in part due to the types of habitats amphibians often thrive in: humid places, favoring the growth of microorganisms. The chytrid fungus in particular also enjoys cool temperatures, so most amphibian species vulnerable to the epidemic inhabit cloud forests.

Ancient, four-legged whale with otter-like features found along the coast of Peru

The presence of small hooves at the tip of the whale's fingers and toes and its hip and limbs morphology all suggest that this whale could walk on land

Cetaceans, the group including whales and dolphins, originated in south Asia more than 50 million years ago from a small, four-legged, hoofed ancestor. Now, researchers reporting the discovery of an ancient four-legged whale--found in 42.6-million-year-old marine sediments along the coast of Peru--have new insight into whales' evolution and their dispersal to other parts of the world. The findings are reported in the journal Current Biology.

When in their evolutionary past did the whales begin to migrate?

Fossil whale barnacles may have the answers

Many whales take long journeys each year, spending summers feeding in cold waters and moving to warm tropical waters to breed. One theory suggests that these long-distance migrations originated around 5 million years ago, when ocean productivity became increasingly patchy. But patterns of ancient whale migrations have, until recently, been shrouded in mystery. Scientists from the Smithsonian Tropical Research Institute (STRI) and the University of California, Berkeley approached this question with an ingenious technique: barnacles.
