Zebra finch call prepares their eggs for climate change



Scientists have long worried whether animals can respond to the planet’s changing climate. Now, a new study reports that at least one species of songbird—and likely many more—already knows how to prep its chicks for a warming world. They do so by emitting special calls to the embryos inside their eggs, which can hear and learn external sounds. This is the first time scientists have found animals using sound to affect the growth, development, behavior, and reproductive success of their offspring, and adds to a growing body of research revealing that birds can “doctor” their eggs.

“The study is novel, surprising, and fascinating, and is sure to lead to much more work on parent-embryo communication,” says Robert Magrath, a behavioral ecologist at the Australian National University in Canberra who was not involved in the study.

The idea that the zebra finch (Taeniopygia guttata) parents were “talking to their eggs” occurred to Mylene Mariette, a behavioral ecologist at Deakin University in Waurn Ponds, Australia, while recording the birds’ sounds at an outdoor aviary. She noticed that sometimes when a parent was alone, it would make a rapid, high-pitched series of calls while sitting on the eggs. Mariette and her co-author, Katherine Buchanan, recorded the incubation calls of 61 female and 61 male finches inside the aviary. They found that parents of both sexes uttered these calls only during the end of the incubation period and when the maximum daily temperature rose above 26°C (78.8°F).

To find out whether the calls somehow prepared the chicks for higher temperatures, the scientists artificially incubated 166 eggs at a standard temperature of 37.7°C (99.9°F). During the last 5 days of incubation, they exposed the eggs to either recorded incubation calls or the parents’ normal contact calls.

Ave australiana canta aos ovos para avisar que está calor


Um mandarim macho CHRIS TZAROS

É uma surpresa no mundo animal. Uma ave australiana consegue activamente influenciar o desenvolvimento da sua descendência quando os embriões ainda estão nos ovos. Nos dias mais quentes, os progenitores da espécie mandarim (Taeniopygia guttata) têm um canto especial para os seus ovos. Isso faz com que os pintos, depois de saírem dos ovos, cresçam menos do que outros indivíduos da espécie que não ouviram o canto especial, mostra um estudo publicado na revista científica Science.

Estudos feitos no passado mostravam que os embriões dentro dos ovos conseguiam ouvir e até emitir sons. Este tipo de comunicação tem importância na vida das aves. Segundo o artigo: “Já se tinha descoberto que a comunicação acústica pré-natal pode influenciar a sincronização da altura em que os pintos saem do ovo e permitir aos embriões pedirem aos progenitores para incubarem os ovos.”

Mas esta capacidade dos mandarins tinha passado despercebida até agora. Estas aves vivem em habitats secos na Austrália. Uma das suas características comportamentais é produzirem ninhadas quando há bom tempo, independentemente das estações do ano.

Mylene Mariette, co-autora do artigo com Katherine Buchanan, ambas do Centro de Ecologia Integrativa da Universidade de Deakin em Waurn Ponds, na Austrália, foi quem identificou a existência destes cantos especiais, que tanto as fêmeas como os machos fazem quando o parceiro ou a parceira está longe do ninho.

A curiosidade levou Mylene Mariette a tentar descobrir a razão destes cantos. A investigadora verificou que os cantos só se davam nos últimos cinco dias do desenvolvimento dos embriões dentro dos ovos e apenas quando a temperatura máxima desse dia ultrapassava os 26 graus Celsius.

througj my window by AHAE





This work was recorded at Mark Knopfler's British Grove Studios in London, UK, with renowned producer Steve McLaughlin, premiered at an exhibition at the Louvre Museum, and performed at Palace of Versailles. This piece was commissioned by an important Korean foundation. Pedro H. da Silva and Lucia N. Caruso performed and recorded on Portuguese guitar and piano.


This is a composition inspired by the photos of birds playing and flying in the snow. It is a co-composition by Lucia Caruso and Pedro Henriques da Silva for the unique combination of Portuguese guitar and piano. 

It uses several themes from other pieces written for photographer AHAE's photos: the ‘falling snow’ motif and main melody from "Snow" by Pedro Henriques da Silva, and the ‘autumn’ and ‘birds taking flight’ themes from "Overture Through My Window: Birds Soaring in Autumn" by Lucia Caruso. Trills on the piano, and the arpeggios and light tremolo on the Portuguese guitar, represent the flight and wing movements of the birds, while the harmonics in the Portuguese guitar, the calm rhythm and frequent high register on both instruments represent cold and serenity in a white winter landscape.

Kairos Quartett

Kairos Quartett Logo

The Kairos Quartet was founded in 1996 and specializes in music written since 1950, including smaller and larger settings. Older music is included on a programme only if there is a significant link to more recent pieces also being played, and if doing so offers additional benefits to the audience.
Compositions are likely to select that are firmly rooted in the tradition of progress and critical reflection, or those connected to it, for example, from another musical tradition. In accordance with these principles the Kairos Quartet has, in eleven years, added more than 40 compositions to the fold through commissions and world premieres. Although the Kairos Quartett has worked with a number of well-known composers such as G. Kurtág, H. Lachenmann, B. Ferneyhough, and G.F. Haas prominence is not a criterium; aside Haas the quartet has also honed long-standing working relationships with composers of widely differing notorieties such as Julio Estrada, Giorgio Netti, Knut Müller, Sergej Newski, Enno Poppe, and Liza Lim.

Acting as a bridge between composer and audience the musicians work closely - whenever possible - with composers and reach out to the audience by offering alternative concert formats (p.e. 1 hour of music + 1 hour of discussion) and workshops. Special emphasis is given to programming concepts and the planning of concert series. Curating and organizing events may also include the production of programme booklets.

Julho de 2016, o mês mais quente da história moderna na Terra

Julho de 2016, o mês mais quente da história moderna na Terra
O mês de julho foi o mais quente da história moderna no planeta Terra, estabelecendo um recorde desde o início dos registos de temperaturas, há 137 anos, anunciaram hoje especialistas norte-americanos.

"A temperatura média global à superfície da terra e dos oceanos foi, em julho de 2016, a mais quente não só dos meses de julho mas de qualquer mês nos anais dos registos de temperaturas da Agência Oceânica e Atmosférica Norte-Americana (NOAA), que remontam a 1880", indicou a instituição.

O anterior recorde tinha sido alcançado em julho do ano passado, sendo este mês tradicionalmente o mais quente do ano na Terra.

Foi também a 15.ª vez consecutiva que um recorde mensal de temperatura foi batido, "a mais longa série deste tipo em 137 anos", referiu a NOAA.

Em julho, a temperatura média global à superfície terrena e à superfície dos oceanos foi de 16,67 graus Celsius, ou seja, 0,87ºC acima da média do século XX. O recorde de 2015 foi batido por 0,06ºC.

Outro sinal do aquecimento global é que julho foi o 379.º mês consecutivo com temperaturas acima da média do século XX. É preciso recuar a dezembro de 1984 para encontrar um registo um pouco inferior à média.

6 Million Americans in 33 States Are Drinking Toxic 'Teflon Chemicals' With Their Water

At least 6 million Americans in 33 states are being exposed to unsafe levels of industrial perfluorooctanoic acid (PFOA) chemicals in their drinking water, found a study published Tuesday in the journal Environmental Science and Technology Letters.
"And the available water data only reveals the tip of the iceberg of contaminated drinking water,"said study co-author Dr. Philippe Grandjean of the Harvard School of Public Health to the Charleston Gazette-Mail.

The Washington Post details the researchers' findings:
194 of 4,864 water supplies across nearly three dozen states had detectable levels of the chemicals. Sixty-six of those water supplies, serving about six million people, had at least one sample that exceeded the EPA's [Environmental Protection Agency] recommended safety limit of 70 parts per trillion for two types of chemicals—perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA).
PFOA and PFOS chemical compounds—including C8, popularly known as the Teflon chemical—areextremely dangerous to human health and despite an EPA advisory released earlier this year and increasing calls for action, research shows they are near-ubiquitous in the U.S.
"Virtually all Americans are exposed to these compounds," Xindi Hu, the study's lead author and a doctoral student at Harvard's Department of Environmental Health, told the Post. "They never break down. Once they are released into the environment, they are there."
Moreover, the study also notes that research suggests "that exposure to these chemicals can make people sick, even at or below the concentration recommended as acceptable under the EPA health advisory," according to the Gazette-Mail.
"The EPA advisory limit ... is much too high to protect us against toxic effects on the immune system," said Grandjean to the Gazette-Mail.

Millions Of Americans May Be Drinking Toxic Water, Harvard Study Finds

The drinking water of some six million people across the country may have elevated levels of unregulated toxic chemicals widely used in the past in many household products — notably pans coated with Teflon — a Harvard-led study published Tuesday found.
Resistant to heat, water, and oil, perfluoroalkyl substances (PFAS) are a class of chemicals that have been used for decades to coat fabric or food packaging, and to manufacture fire-fighting foams and Teflon pans. Now mostly phased out in the U.S., PFAS went unregulated and were often disposed in watersheds. These chemicals are persistent in the environment and have beenlinked to adverse health effects in animals, according to the EPA. In humans, PFAS have been linked to a wide range of illnesses, including birth defects,cancer, and immune system dysfunction, according to multiple studies.
“These compounds have been used for over 60 years and it is only in the most recent years that we’ve began to understand how serious this pollution is, and how toxic [PFAS] are,” Philippe Grandjean, co-author and adjunct professor of environmental health at Harvard University, told ThinkProgress.
According to the study published in Environmental Science & Technology Letters, 75 percent of public water systems that exceeded PFAS federally recommended safety levels (updated this year) were found in 13 states: Alabama, Arizona, California, Florida, Georgia, Illinois, Minnesota, Massachusetts, New Jersey, North Carolina, New York, Ohio, and Pennsylvania. While PFAS are largely on their way out, the substitutes are at times chemically related and could still be toxic, recent studies have found.
National sampling of PFASs and some related chemicals like PFOAs began in 2013, under an EPA program that requires all public water systems serving at least 10,000 people to test for unregulated contaminants. While the EPA uses this assessment to figure out if contamination warrants regulation, the Harvard study used EPA data compiled from 2013 through 2015 to map the link between potential sources of pollution and drinking water contamination.

Study raises questions about measuring radioactivity in fracking wastewater - Apr. 9, 2015



Commonly used testing methods may underestimate the total radioactivity of wastewater produced by gas wells that use hydraulic fracturing, or fracking, to tap the Marcellus Shale, a geological formation in the northeastern United States, concludes a new study. The findings suggest government agencies should consider retooling some testing recommendations and take a fresh look at possible worker exposure to potentially harmful waste, the authors say. But some outside researchers are skeptical that the laboratory study reflects real-world conditions.
Fracking, which involves injecting water mixed with chemicals and sand deep underground in order to fracture rock and release oil and gas, generates large amounts of wastewater. Some of the waste is simply injected water that flows back to the surface. But in the Marcellus and other formations, a major waste component is salty, mineral rich water found naturally underground. Researchers have long known that this natural brine can carry radioactive components, including radon gas, radium, and other isotopes of uranium and thorium. And the waste’s radioactivity has gotten increased attention as a fracking boom in the Marcellus has resulted in the recovery of millions of liters of wastewater, which is typically stored, treated, or recycled for use in other fracking wells. In some cases, improper handling has resulted in the release of radioactive fracking waste that has contaminated streams and rivers.
Last year, Andrew Nelson, a doctoral candidate in human toxicology at the University of Iowa in Iowa City, helped the U.S. Environmental Protection Agency (EPA) write an analysis that concluded that agency-recommended testing methods may understate some measures of radioactivity. Although EPA does not regulate most oil and gas activities, laboratories that test water for state regulators, oil and gas producers, and wastewater treatment plants often rely on the agency’s recommended methods. One problem with current EPA techniques, the report found, is that they focus on levels of radium in fresh water used for drinking, and so do not work well with fracking waste. In part, that’s because Marcellus Shale wastewater is saltier than seawater; it also holds other potentially problematic radionuclides in addition to radium.
Now, in a paper published online on 2 April in Environmental Health Perspectives, a team led by Nelson shows that radium-focused tests can significantly underestimate the total radioactivity of wastewater that is stored in closed containers, such as tanks. The researchers found the testing methods don’t fully measure radium’s daughter decay products, which can build up in the days and years after the briny waste reaches the surface. Radioactivity levels in stored wastewater can rise fivefold within 15 days, for example, and continue to rise for decades.
To undertake their study, the researchers obtained a sealed sample of Marcellus wastewater and then measured selected radioactive isotopes that appeared as radium decayed into daughter products. The half-lives, radioactivity, and chemistry of radium isotopes and their decay products vary considerably, the researchers note. For example, the half-life of radium-226 is 1600 years (meaning it takes that long for 50% of the total to decay). In contrast, lead-210’s half-life is 22.2 years, while polonium-210’s is 138.4 days. To calculate the total radioactivity of a sample over time, researchers must account for all of these daughter products.
At first, the researchers could barely detect the presence of many daughter isotopes, including polonium-210 and lead-210. Over time, however, the levels rose as the decay reactions took place and continued to rise for months.
Just how much risk these radioactive isotopes might pose to people exposed to the waste is unclear. One issue is that the researchers used a sealed sample, which meant that radon gas that gives birth to daughter isotopes could not escape into the air. At real-world fracking sites, however, the radon may escape from the wastewater as it emerges from the wellhead, sits in collecting ponds, or is transferred between containers, notes environmental engineer Radisav Vidic of the University of Pittsburgh in Pennsylvania, who was not involved in the study. “If radon gas leaves the solution you stop the subsequent creation of the daughter products,” he says.
One of the study’s authors, however, notes that the half-lives of some of the radioactive products are so short that they could still pose problems in the days after the waste surfaces, before radon has a chance to escape. Radon-220, for instance, has a half-life of just 55.6 seconds. “That means that it’s unlikely to escape before the other daughters are formed,” says co-author Michael Schultz, a radiochemist at the University of Iowa. And even if some radon gas does escape, more can be generated in closed containers as any remaining radium decays, Nelson adds.
Another issue is uncertainty about the health risks posed by the different isotopes. Some are considered to pose a greater risk because they emit radiation that can penetrate the body, while others are considered less risky because they must be inhaled or ingested to do damage. And some can accumulate in the food chain, with long-lived isotopes potentially posing a threat for decades.
Given such unknowns, “we have yet another reason to be concerned about understanding exposure related to the hydraulic fracturing procedures,” says environmental toxicologist Bernard Goldstein, a professor emeritus at the University of Pittsburgh Graduate School of Public Health, who was not involved in the study. “They’ve made a very good case that we need a much more thorough evaluation of worker exposure at different places at different times,” he says.
David Allard, director of Pennsylvania’s Bureau of Radiation Protection in Harrisburg, says the new study’s findings agree with those of a recent state analysis of radioactive fracking wastewater, particularly regarding radon decay in sealed containers. But Allard believes there is little risk to the public or workers of exposures exceeding international radiation standards during normal fracking procedures. But he adds that spills of fracking wastewater may pose some additional risk because it can carry radium-226 into ground water.
Allard agrees that tests tailored to waste from oil and gas operations are needed. Although EPA has recognized potential problems with current testing methods for use on fracking wastewater, it is not clear whether the agency is contemplating new recommendations. “EPA does not have authority to regulate [hydraulic fracturing] wastewaters as they are generated,” said an EPA representative in a statement. Its “non-regulatory” testing methods, the statement noted, are available only “as a tool for hydraulic fracturing.”

Study raises questions about drinking water safety in US





Temperaturas vão descer e aguaceiros podem ocorrer no norte

Temperaturas vão descer e aguaceiros podem ocorrer no norte


As temperaturas deverão baixar esta tarde e podem ocorrer aguaceiros no norte e centro, condições que permitirão levantar os avisos meteorológicos de calor, disse fonte do IPMA, acrescentando que o risco de incêndio poderá descer no litoral, na segunda-feira.

"Para hoje [o risco de incêndio] ainda é bastante elevado, principalmente nos distritos do interior norte e centro", apesar da possibilidade da ocorrência de aguaceiros, referiu à Lusa a fonte do Instituto Português do Mar e da Atmosfera (IPMA).

Na segunda-feira, "o risco ainda [vai] manter-se elevado nas regiões do interior centro, como alto Alentejo, e no litoral [vai] diminuir bastante", referiu.

As temperaturas "descem e os avisos emitidos terminam ao final do dia, não serão para prolongar", avança o IPMA.

Na informação meteorológica do IPMA, estão oito distritos de Portugal continental sob 'Aviso Amarelo' devido à previsão de temperaturas elevadas.

"Durante a tarde, nas regiões do interior norte e centro, principalmente nas áreas montanhosas [poderá haver] condições favoráveis para o aumento da nebulosidade com a ocorrência de aguaceiros e trovoada", explicou o IPMA.

O vento tem estado fraco, havendo situações de moderado durante a tarde no litoral oeste, além de vento sudoeste na costa sul do Algarve, uma tendência que deverá manter-se.

Os próximos dias vão ter sempre alguma nebulosidade no litoral oeste, principalmente no norte e centro, e na segunda-feira volta uma situação de instabilidade nas regiões do interior, com aumento da nebulosidade e condições favoráveis a aguaceiros e trovoadas, em especial durante a tarde e nas regiões montanhosas do norte e centro.

Está prevista uma pequena descida da temperatura, quer da máxima, quer da mínima, embora esta tenha uma quebra mais acentuada.

Na terça-feira, o vento mantém as condições dos dias anteriores e regista-se "alguma nebulosidade no litoral oeste até meio da manhã e para o final da tarde no norte".

Na quarta-feira, com a aproximação de uma superfície frontal fria, "nas regiões norte e centro temos mais nebulosidade no litoral, um céu muito nublado, e períodos de chuva ou aguaceiros, em geral fracos, a partir do início da manhã e em especial no litoral", avançou a fonte do IPMA.

Na temperatura, aparece uma pequena subida na mínima no litoral norte e centro, e uma pequena descida da máxima, enquanto no sul do país apenas é referida uma descida dos valores mais elevados.

Para quinta-feira, a tendência aponta para que possa ocorrer precipitação no final do dia, no Minho e Douro e litoral, "mas ainda há alguma incerteza".
