Amphibians living close to farm fields are more resistant to common insecticides

May 1, 2013 ? Amphibian populations living close to agricultural fields have become more resistant to a common insecticide and are actually resistant to multiple common insecticides, according to two recent studies conducted at the University of Pittsburgh.Amphibian populations living close to agricultural fields have become more resistant to a common insecticide and are actually resistant to multiple common insecticides.

In a study published today in Evolutionary Applications, the Pitt researchers demonstrate, for the first time, that tadpoles from populations close to farm fields are more resistant to chlorpyrifos -- one of the most commonly applied insecticides in the world, often sold as "Dursban" or "Lorsban." In addition, a related study published in February shows that tadpoles resistant to chlorpyrifos are also resistant to other insecticides.

"While we've made a lot of progress in understanding the ecological consequences to animals that are unintentionally exposed to insecticides, the evolutionary consequences are poorly understood," said study principal investigator Rick Relyea, Pitt professor of biological sciences and director of the University's Pymatuning Laboratory of Ecology. "Our study is the first to explore how amphibian populations might evolve to be resistant to insecticides when they live in places that have been sprayed for many years."

The Pitt researchers used newly hatched tadpoles collected from nine populations of wood frogs living at different distances from agricultural fields. They tested the frogs' resistance when exposed to chlorpyrifos, which is used against insects, and Roundup Original MAX?, which is a common herbicide used against weeds.

Relyea and his Pitt collaborators exposed the tadpoles from each of the nine populations to environments containing either no pesticides, chlorpyrifos, or Roundup?. After 48 hours, they measured how well the populations survived.

"Wood frogs living close to agricultural land were more likely to have been exposed to pesticides for many generations compared to those living far from agriculture; the latter frog populations likely experienced little or no exposure to pesticides," said Rickey Cothran, the lead author of the study and a postdoctoral researcher in Relyea's lab. "Although populations differed in their resistance to Roundup?, populations closer to fields were not more resistant to the herbicide."Wood frogs living close to agricultural land were more likely to have been exposed to pesticides for many generations compared to those living far from agriculture.

"Because chlorpyrifos kills in a way that is similar to many other insecticides, higher resistance may have been favored each time any insecticide was sprayed," said Pitt alumnus Jenise Brown (A&S '09), a coauthor of the study and a former undergraduate researcher in Relyea's lab. "In contrast, herbicides have a variety of ways that they kill organisms, which may make it harder for animals to be resistant when exposed to different herbicides over many years."

In a related study, published online Feb. 21 in Environmental Toxicology and Chemistry, Relyea's Pitt research team examined whether wood frog populations that were resistant to chlorpyrifos might also be resistant to other insecticides. This phenomenon, said Relyea, happens commonly in pest species when farmers switch pesticides from year to year, but little is known about how this switching of pesticides affects amphibians.

Using three commonly applied pesticides that have similar chemical properties -- chlorpyrifos, carbaryl, and malathion -- the Pitt researchers exposed 15 populations of wood frog tadpoles to high concentrations of each insecticide. They found that wood frog populations with resistance to one insecticide also had resistance to the other insecticides.

"This has a beneficial outcome," said Jessica Hua, the lead author of the second study and a graduate student in Relyea's lab. "While it doesn't mean that pesticides are beneficial to amphibians, our work does suggest that amphibians can evolve to resist a variety of pesticides and therefore improve their survival."

As they hypothesized in the study published today, the researchers suspect that the reason for this cross-resistance is that chlorpyrifos kills in a way that is similar to many other insecticides. Thus, evolving higher resistance to one insecticide may provide higher resistance to others.

"This finding may buffer an amphibian population from suffering the consequences of exposures to new, but similar-acting chemicals," said Aaron Stoler, a coauthor of the second paper and a graduate student in Relyea's lab.

In the future, Relyea and his team plan to study the genetic mechanisms that underlie increased resistance in amphibians and determine whether increased resistance occurs in additional animal species that are not the targets of pesticides.

The article published today in Evolutionary Applications is titled "Proximity to agriculture is correlated with pesticide tolerance: Evidence for the evolution of amphibian resistance to modern pesticides." The article published Feb. 21 in Environmental Toxicology and Chemistry is titled "Cross-tolerance in amphibians: Wood frog mortality when exposed to three insecticides with a common mode of action."

Funding for both studies was provided by a National Science Foundation grant to Relyea. Funding for the second study was also provided by Pitt's G. Murray McKinley Research Fund to Hua and Stoler. The experiments were conducted at Pitt's Pymatuning Laboratory of Ecology from 2009 to 2012.

Gene Mutation Linked to Migraines, Researchers Say - Health News ...

WEDNESDAY, May 1 (HealthDay News) ? Researchers say they?ve identified a gene mutation associated with a typical form of migraine headache.

The causes of migraine headaches are unknown. Between 10 percent and 20 percent of people suffer from the debilitating, recurrent headaches.

For the new study, published May 1 in the journal Science Translational Medicine, researchers analyzed the genetics of two families in which migraines were common. They found that many of the migraine sufferers had either a mutation in the casein kinase I delta (CKIdelta) gene or were the children of a parent with the mutation.

In laboratory cells, the researchers found that the mutation affects production of the CKIdelta enzyme, which performs vital functions in the brain and body.

Further experiments in mice suggested more evidence of a connection between this gene mutation and migraines.

?This is the first gene in which mutations have been shown to cause a very typical form of migraine,? senior investigator Louis Ptacek, a professor of neurology at the University of California, San Francisco, said in a university news release.

?It?s our initial glimpse into a black box that we don?t yet understand,? added Ptacek, who also is an investigator at UCSF?s Howard Hughes Medical Institute.

Migraines cause ?huge losses in productivity, not to mention immense suffering,? Ptacek said. Symptoms include a throbbing headache, hypersensitivity to sound and touch, and aura, which Ptacek described as ?a visual sensation that presages the headache to come.?

There are good migraine drugs available now, ?but they only help some patients, some of the time,? he said. ?The need for better treatments is huge.?

?[This research] puts us one step closer to understanding the molecular pathway to pain in migraine,? he said. With a better understanding of the condition, ?we can start thinking about better therapies. Certain molecules might be targets for new drugs.?

Ptacek said the CKIdelta gene is not the only mutation likely to be associated with migraines. ?There are likely several, in different combinations in different people,? he said. ?This is simply the first one we?ve found.?

One step closer to a quantum computer

Apr. 30, 2013 ? Professor Weimin Chen and his colleagues at Link?ping University, in cooperation with German and American researchers, have succeeded in both initializing and reading nuclear spins, relevant to qubits for quantum computers, at room temperature.

The results have just been published in the journal Nature Communications.

A quantum computer is controlled by the laws of quantum physics; it promises to perform complicated calculations, or search large amounts of data, at a speed that exceeds by far those that today's fastest supercomputers are capable of.

"You could say that a quantum computer can think several thoughts simultaneously, while a traditional computer thinks one thought at a time," says Weimin Chen, professor in the Division of Functional Electronic Materials at the Department of Physics, Chemistry and Biology at LiU, and one of the main authors of the article in Nature Communications.

A traditional computer stores, processes and sends all information in the form of bits, which can have a value of 1 or 0. But in the world of quantum physics, at the nano- and atomic level, other rules prevail and a bit in a quantum computer -- a qubit -- can have any value between 1 and 0. A spin-based qubit makes use of the fact that electrons and atomic nuclei rotate around their own axes -- they have a spin. They can rotate both clockwise and counterclockwise (equivalent to 1 and 0), and in both directions simultaneously (a mix of 1 and 0) -- something that is completely unthinkable in the traditional, "classical" world.

An atomic nucleus consists of both protons and neutrons, and the advantage of using the nuclear spin as a qubit is that the nucleus is well protected, and nearly impervious to unwanted electromagnetic disturbance, which is a condition for keeping the sensitive information in the qubit intact.

The first step in building a quantum computer is to assign each qubit a well-defined value, either 1 or 0. Starting, or initiating, the spin-based qubits then requires all the atomic nuclei to spin in the same direction, either 'up' or 'down' (clockwise or counterclockwise). The most common method for polarising nuclear spin is called dynamic nuclear polarisation; this means that the electrons' spin simply influences the nucleus to spin in the same direction. The method requires strongly spin polarised electrons and functions superbly at lower temperatures. Dynamic nuclear polarisation via conduction electrons has, however, not yet been demonstrated at room temperature -- which is crucial for the method to be useful in practice for the development of quantum computers. The main problem is that the spin orientation in the electrons can easily be lost at room temperature, since it is sensitive to disruptions from its surroundings.

Link?ping University researchers Yuttapoom Puttisong, Xingjun Wang, Irina Buyanova and Weimin Chen, together with their German and American colleagues, have now discovered a way of getting around this problem.

Back in 2009, Chen and his research group presented a spin filter that works at room temperature; the filter lets through electrons that have the desired spin direction and screens out the others.

With the help of the spin filter, they have now succeeded in producing a flow of free electrons with a given spin in a material -- in this case GaNAs (gallium nitrogen arsenide). The spin polarisation is so strong that it creates a strong polarisation of the nuclear spin in extra Ga atoms that are added as defects in the material -- and this takes place at room temperature. This is the first time that strong nuclear spin polarisation of a defect atom in a solid is demonstrated at room temperature by spin-polarised conduction electrons.

"We prove experimentally that the measurable magnetic field from the nuclei, as well as the strong polarisation of the nuclear spins in the material at room temperature, comes from the dynamic polarisation of the nuclear spin in the extra added Ga atoms," says Chen.

The researchers have also shown that the polarisation of the nuclear spin happens very quickly -- potentially in less than a nanosecond (one-billionth of a second).

The method proposed also has the advantage of making use of free electrons. This makes it possible to control the polarisation of the spin in the nucleus electrically; in this way the information lying in the spin can both be initiated and read.

How Doctors Would Know If Syrians Were Hit With Nerve Gas

Doctors at a hospital in Aleppo, Syria, treat a boy injured in what the government said was a chemical weapons attack on March 19. Syria's government and rebels accused each other of firing a rocket loaded with chemical agents outside of Aleppo.

Doctors at a hospital in Aleppo, Syria, treat a boy injured in what the government said was a chemical weapons attack on March 19. Syria's government and rebels accused each other of firing a rocket loaded with chemical agents outside of Aleppo.

George Ourfalian/Reuters/Landov

President Obama affirmed Tuesday that there's evidence Syrians have been attacked with chemical weapons ? in particular, nerve gas.

But that's not the same as proof positive.

"We don't know how they were used, when they were used, who used them," Obama said. "We don't have a chain of custody that establishes what exactly happened."

Proving that someone has violated the international taboo on chemical weapons can be very hard. While governments seek more evidence, Syrians may be in danger.

That's why a physicians' organization is trying to help medical workers in Syria recognize the signs of a chemical attack. The effort is meant to save lives, but it could also generate evidence that governments are seeking.

Physicians for Human Rights is setting up a network to get fact sheets about chemical weapons into the hands of Syrian physicians. This group has a long record of working with medical professionals in trouble spots to protect civilians and reveal war crimes.

The fact sheets list the symptoms of exposure to mustard gas or nerve gases, like sarin and VX. They explain how to treat people and how doctors can avoid being contaminated themselves.

Getting this information to Syrians is also important to rule out false alarms, says Susannah Sirkin, who directs PHR.

"There are times when symptoms may look to doctors as if they were caused by chemical warfare agents," she says. "They might mistake other kinds of injuries or harms in a hot conflict with chemical warfare agents."

False alarms could cause panic or, as happened in Iraq, lead the U.S. military to take action based on inaccurate claims about weapons of mass destruction.

The fact sheets also explain how to take samples of blood, urine and hair from patients and preserve them as evidence. "Obviously, if these weapons are being used, have been used or might be used soon, it's in everyone's interest that this be known and that they be identified," Sirkin says.

That sample analysis would likely be done outside Syria.

Toxicologist Alastair Hay, from the University of Leeds, says nerve agents leave a trail in the body.

They attack a crucial enzyme that normally works like an on-off switch between nerves and muscles. A nerve gas eliminates the "off" signal. "Basically it's on, on, on, on, on all the time," Hay, who also works with PHR, says. "So you then get a whole range of effects. ... [It's] absolutely dreadful."

Things like terrible headaches, sweating, seizures and respiratory failure, which can lead to death.

But other ailments ? like pesticide exposure ? produce similar symptoms that can be mistaken for nerve gas exposure.

So the gold standard of proof for nerve gas, Hay says, is tracking down the agent itself in tissue samples.

"The chemical nerve agent will be attached to the enzyme," Hay says. "It physically inactivates the enzyme and remains attached to it." You can track down and isolate that nerve agent even weeks after a person is exposed, he says.

Physical samples of nerve agent in soil are harder to get because nerve gas evaporates quickly. But Hay and PHR succeeded in doing that in 1992.

They brought back soil and a contaminated piece of a bomb from northern Iraq, confirming that Saddam Hussein's forces gassed Kurdish civilians there.

But getting samples is just the start, Hay notes. To make a legal case ?whether it's against the Syrian government or opposition group ? you need an ironclad chain of custody. "You need to be able to have somebody swear, if you like, that the material was in their custody at all times, whoever it is with before it gets to a laboratory," Hay says.
