Can water-polluting drugs have a positive effect on fish?
August 8, 2014 08:13 AM - Editor, ENN
Many studies have shown that personal care products, like toothpaste, shampoo, and other drugs that we use and get into our wastewater have negatively affected fish populations, disrupting their endocrine systems. But can there be any positive effects? A new study shows that one antianxiety drug that made its way into a lake in Sweden has in fact, positively affected the Eurasian perch population, making them bolder, less social, and more active than unexposed fish, ultimately reducing their mortality rates.
Elephants Under The Sea
August 7, 2014 09:33 AM - Shreya Dasgupta, MONGABAY.COM
Bumphead parrotfish are noisy feeders. They break off large branches of corals using their powerful beaks, grind them up in their bodies to extract nutrients, and expel the undigested material in large cloudy plumes of feces. Their voracious feeding is, however, not just a loud, messy affair. During the course of their feeding, bumphead parrotfish (Bolbometopon muricatum) also change the coral reef ecosystem in numerous ways, a new study published in Conservation Biology has found.
Are humans impacting the deep Earth?
August 7, 2014 09:31 AM - Alex Peel, Planet Earth Online
Human forays deep underground, such as boreholes, mines and nuclear bomb tests, are leaving a mark on the planet's geology that will last for hundreds of millions of years, say scientists. In a new report, published in the journal Anthropocene, they say we are altering Earth's rocks in a way that's unique in the planet's 4.6 billion-year history.
Marine noise impacts eels too!
August 7, 2014 08:45 AM - Roger Greenway, ENN
Marine noise has been studied for it's impact on whales, dolphins and other marine animals. Might it also impact smaller creatures too? Eels, for example. Despite their reputation as slippery customers, a new study has shown that eels are losing the fight to survive when faced with marine noise pollution such as that of passing ships. Scientists from the Universities of Exeter and Bristol found that fish exposed to playback of ship noise lose crucial responses to predator threats. The study, published today in the journal Global Change Biology, found European eels were 50 per cent less likely to respond to an ambush from a predator, while those that did had 25 per cent slower reaction times. Those that were pursued by a predator were caught more than twice as quickly when exposed to the noise.
Mercury in the oceans increasing
August 6, 2014 05:29 PM - Woods Hole Oceanographic Institution
Although the days of odd behavior among hat makers are a thing of the past, the dangers mercury poses to humans and the environment persist today. Mercury is a naturally occurring element as well as a by-product of such distinctly human enterprises as burning coal and making cement. Estimates of "bioavailable" mercury—forms of the element that can be taken up by animals and humans—play an important role in everything from drafting an international treaty designed to protect humans and the environment from mercury emissions, to establishing public policies behind warnings about seafood consumption.
How Did Ebola Zaire Get To Guniea?
August 6, 2014 04:13 PM - Daniel Stiles, MONGABAY.COM
Is the great ape trade responsible for the current outbreak of Ebola? The vicious Ebola virus outbreak that has already killed more than 800 people this year, in addition to sowing panic, fear and confusion throughout West Africa, was not a strain endemic to the region as initially believed. Instead the University of Edinburgh found that the strain is the same as the Ebola Zaïre found in the Democratic Republic of Congo (DRC), formerly Zaïre. TheRobert-Koch Institute in Germany confirmed the finding.
New Zoo Concept Boasts No Cages
August 6, 2014 08:44 AM - Alicia Graef, Care2
Danish architects are taking on the task of creating a zoo environment that will change what the face of captivity looks like in the future with the reveal of plans for what it's calling the "world's most advanced zoo." The Givskud Zoo in Denmark has accepted a design from the Bjarke Ingels Group (BIG) that has no cages and will allow animals to live in environments that mimic their natural habitats. The first phase is expected to be completed by 2019, just in time for the park’s 50th anniversary.
New Jersey bans Ivory sales
August 6, 2014 07:34 AM - Wildlife Conservation Society
The state of New Jersey has enacted a statewide ban on sales of Ivory. The following statement was issued by John Calvelli, Wildlife Conservation Society Executive Vice President of Public Affairs and Director of the 96 Elephants Campaign: "Today is an historic day for elephants and conservation. The Wildlife Conservation Society and the 96 Elephants campaign praises N.J. Governor Chris Christie for signing into law a statewide ban on ivory sales."
The Danger of Solar "Super-Storms"
August 5, 2014 01:45 PM - Winfield Winter, ENN
Watch out George Lucas fans, a Death Star may be in our horizons — and one would only have to look as far as our nearest stellar neighbor: the Sun. According to Mr. Ashley Dale of the University of Bristol, solar "super-storms" pose an imminent threat to the earth by disabling electricity and communication system — or worse. Thus, the celestial body that illuminates the world may very well be responsible for sending it into darkness. In this month's issue of PhysicsWorld, Mr. Dale writes: "Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online. Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases behind centuries ago soon returning."
A lake appears in Tunisia desert!
August 5, 2014 12:46 PM - Laurie Balbo, Green Prophet
Tunisia offers other-worldly landscapes, fantastical and mysterious. Did you know that four of the Star Wars movies were partially filmed in the southern part of the country? (Tunisia had a starring role as the planet Tatooine). Now, adding to the Atlas mountains and Sahara desert, the tiny republic has another tourist attraction — a newborn lake. Discovered by shepherds just last month in the middle of Tunisian desert, there has been no official explanation for its sudden appearance. Some geologists have proposed that seismic activity may have disrupted the natural water table, pushing water from underground aquifers to the surface. Others disagree.
