Bisphenol A (BPA) is a chemical used in many consumer products including water bottles, metal food storage products and certain resins. Often, aquatic environments such as rivers and streams become reservoirs for BPA, affecting turtle habitats. Last year, a team of researchers led by the University of Missouri determined that BPA can disrupt sexual function in painted turtles, causing males to develop female sex organs. Now, the team has shown that BPA also can induce behavioral changes in turtles, reprogramming male turtle brains to show behavior common in females. Researchers worry this could lead to population declines in painted turtles.
"Previously, our research team found that BPA and ethinyl estradiol (EE2), a hormone found in birth control pills, could 'sex-reverse' turtles from males to females," said Cheryl Rosenfeld, an associate professor of biomedical sciences in the MU College of Veterinary Medicine and an investigator in the Bond Life Sciences Center. "Painted turtles and other reptiles lack sex chromosomes. The gender of painted turtles and other reptiles is determined by the incubation temperature of the egg during development. Studies have shown thatexposure to endocrine-disrupting chemicals (EDCs), such as BPA, can override incubation temperature and switch the sex of males to females. In our latest study, we found that BPA also affects how the male brain is 'wired,' potentially inducing males to show female type behavioral patterns."
Comment: Turtles are not the only species that are being affected by BPA because similar effects have also been found to occur in humans.
Authorities in Geneva have put down a rutting deer that attacked four people over the course of 48 hours, according to reports.
The buck went on the rampage at the end of July in a residential area in the Collonge-Bellerive area of Geneva, newspaper 24 Heures said on Thursday.
Describing his experience to the paper, one of the animal's victims, José Taboada, said he was driving his van through the area on July 25th when he saw it leap out of a sunflower field a few metres from his vehicle.
Taboada got out of the van to take a photo of the buck with his phone when it attacked.
When a young woman went for a swim in an idyllic south Bavarian region, she got more than she bargained for.
The woman was swimming in a lake in Straubing-Bogen in southeastern Bavaria when the huge flesh-eating fish bit into her leg, the Süddeutsche Zeitung (SZ) reported on Wednesday.
She immediately turned round and was able to swim back to the shore in safety. But the large bite left in her leg allowed experts to estimate that the beast - a wels catfish - that had a nip at her was around two metres in length, about 6.5 feet.
An expert from the Bavarian Fishing Association told the SZ that such incidents are not wholly uncommon, especially when the male is protecting a pair's eggs.
A second victim of the freak Aug. 12 lightning strike in a City of Poughkeepsie park has died.
The 46-year-old man died at 6:15 a.m. Wednesday, according to John Nelson, director of public and community affairs at Vassar Brothers Medical Center.
The man, whose name was not released, was the second man fatally struck in City of Poughkeepsie's Mansion Square Park that Friday afternoon. A 50-year-old man died early the following day.
Three other lightning strike victims, Alexander Carr, Karen Brooks and an unnamed 46-year-old man, were treated at local hospitals following the strike and released.
Lightning struck a tree, traveling down it and into the ground, shocking five victims on or near a bench, one of whom died. Police have not released the names of the victims.
In a gross natural disaster, a total of 38 sheep were killed on Tuesday night as lightning struck the Kammalam Poondy village in Kanchipuram district.
The catastrophe had left the village in a pall of gloom and is a first of its kind in the recent past, said the distressed villagers.
Cattle owner E. Lakshmanan (45), who lost 38 sheep among the 104 ones, has incurred a loss of Rs 1.52 lakh. As brief spells and thunderstorms were observed on Tuesday evening, Lakshmanan had chosen to not take the cattle to a fenced field and left them in an open ground, a few yards behind his house. At around 11pm, he woke up to the disturbance and was shocked to see the carcasses of the cattle.
Rescuers continued to search for survivors in central Italian towns devastated by a 6.2-magnitude earthquake as the number of victims rose to 247 on Thursday morning. Accounts of lucky escapes and tragedies have emerged as communities struggle to cope with the aftermath.
Italy's earthquake death toll has climbed to 247, local wire service ANSA quoted regional officials as saying.
Meanwhile, the European-Mediterranean Seismological Centre (EMSC) reported yet another 4.6-magnitude earthquake hit central Italy, some 66 km northeast from the town of Terni, with a population of over 220,000 people. It was the 22nd quake in the region in less than 24 hours.
The dramatic rescue operation continued overnight into the early hours of Thursday as scores of people are still believed trapped under the rubble. Thousands have been left homeless.
At least 86 victims come from the small towns of Amatrice and Accumoli that lie close to the epicenter of the quake, about 100 km from Rome.
Comment: An earthquake of comparable force hit the nearby city of L'Aquila in 2009, killing 309 people. In the subsequent 'witch hunt' seven seismologists were convicted of manslaughter for failing to adequately assess the earthquake risk. In 2012 they were sentenced to six years in prison, six were acquitted two years later.
This is one of the most seismically active parts of Italy as clearly identified in many seismic hazard maps. Addressing the fundamental reason for such tragic loss of life, Kevin McCue, president of the Australian Earthquake Engineering Society, said
"This earthquake occurred in an area rated a high earthquake hazard region of Italy. Buildings should be designed and built to withstand this level of shaking without collapse. That they don't is typical of the attitude to the hazard in Italy and Australia where the risk of being killed in a vehicle accident is much higher."
Mr Renzi, the Italian prime minister,says "Our credibility and honor depends on a real reconstruction that would prevent the inhabitants of these municipalities from leaving, to allow these beautiful places to start over."
The reason why so many buildings fall down in Italy during earthquakes is that many were put up without planning consent, with the structural guarantees that normally accompany it; but more specifically buildings have simply not been designed and built with due consideration to the seismic threat, like in Japan for instance.
According to the government own statistics office, unlawful construction in Italy is of "dimensions unparalleled in other advanced economies". The latest estimate, for 2014, is that 18% of buildings are erected without permission, excluding extensions.
Unless these planning and construction laws are completely overhauled further tragedies such as this are inevitable.
At least 300 people have died in eastern and central India and more than 6 million others have been affected by floods that have submerged villages, washed away crops, destroyed roads and disrupted power and phone lines, officials say.
Heavy monsoon rains have caused rivers, including the mighty Ganges and its tributaries, to burst their banks forcing people into relief camps in the states of Madhya Pradesh, Bihar, Uttar Pradesh, Rajasthan and Uttarakhand.
Government officials in Bihar, which has seen some of the worst flooding this year with almost 120 dead and more than 5 million affected, said the situation was serious.
"The flood waters have engulfed low-lying areas, homes and fields of crops," said Zafar Rakib, a district magistrate of Katihar, one of 24 districts out of Bihar's 38 districts which have been hit by the deluge.

Hundreds of thousands of fish turned up dead in a creek in New Jersey this week, prompting environmental officials to investigate.
The Department of Environmental Protection said the dead fish found in Waackcaack Creek in Keansburg are peanut bunker, which is a name used to describe Atlantic Menhaden when they are first developing after hatching. Officials believe they were likely chased into the creek by either bluefish or skates.
The peak of the dead fish appeared to be Saturday, said Bob Considine, a spokesman for the DEP.
"Although the water is tidal, the creek and other surrounding waters where the fish have washed up can get stagnant during certain tides and we believe at this point that the die off is due to dissolved oxygen levels in the water," Considine said.

Sometimes people hold a core belief that is very strong. When they are presented with evidence that works against that belief, the new evidence cannot be accepted. It would create a feeling that is extremely uncomfortable, called cognitive dissonance. And because it is so important to protect the core belief, they will rationalize, ignore and even deny anything that doesn't fit in with the core belief.
