Why Won?t the FBI Tell the Public About its Drone Program?

Why Won?t the FBI Tell the Public About its Drone Program?

Today we?re publishing?for the first time?the FBI?s drone licenses and supporting records for the last several years. Unfortunately, to say that the FBI has been less than forthcoming with these records would be a gross understatement.

New Leak Perhaps Possibly Shows the New iPhone's Rear End

New Leak Perhaps Possibly Shows the New iPhone's Rear EndMacRumors has laid its hands on a couple of images purporting to show the inside and rear shell of the next iPhone.

The images seem to show the same logic board that appeared in a leak earlier this week. While the main chip isn't conventionally branded with an Apple A-series prefix, the date stamp suggests that the silicon was manufactured on the 43rd week of 2012. Rather older than expected, that suggests that this could be a very early prototype. Or, perhaps, fake. Difficult to tell.

Elsewhere, the rear shell looks broadly similar to the current iPhone 5, though it does sport a a vertical pill-shaped window for the LED flash. That suggests a dual LED flash, rather than the single one found on current iPhones. While there's no telling if this is the real deal or otherwise, subtle incremental changes are perhaps more believable than grand sweeping redesigns. Regardless, expect to see much more where this came from over the coming months. [Mac Rumors]

54% of pregnant women use insecticides that are harmful to the fetus, Spanish study shows

June 20, 2013 ? Pregnancy and infancy are the periods of greatest vulnerability to the use of household insecticides. This is one of the findings of the first study of its kind to be carried out in Spain, which concludes that more than half of expectant mothers routinely use these chemical compounds.

Spanish researchers have described the use of domestic pesticides during pregnancy and the first year of life in nearly 2,500 women and children in Sabadell, Guip?zcoa and various areas of Asturias and the Valencian Community.

The study, published in Science of the Total Environment, also considers the socio-demographic and lifestyle factors most strongly linked to the use of these pesticides.

In 2003 and 2008, the authors monitored the women who agreed to take part in the project from the beginning of their pregnancy until birth and during their offspring's first few years of life.

"Pesticides are used in domestic environments to control infestations of insects or other living creatures," explains Sabrina Llop from the Higher Public Health Research Centre (CSISP) in Valencia, the leading author of the paper. "Exposure during pregnancy or infancy proves to have a negative impact on fetal growth and neurological effects, as well as increasing the risk of childhood leukemia," she continues.

The results show that 54% of pregnant women used some kind of insecticide inside the home and 15% made use of a combination of two or three methods.

45% of women used some kind of insecticide in their bedrooms: 5% throughout the whole year, 75% seasonally and 20% on an occasional basis. The most frequently used method in the bedroom was the electric device at 62%.

47% of pregnant women used insecticides in the rest of the house, 7% throughout the whole year, 67% seasonally and 26% occasionally. The most widely used method by women in other areas of the house was insecticide spray at 69%.

2% of women used other kinds of measures to control infestations in their bedrooms and 5% in the rest of the house. These other measures included cockroach traps, powder insecticide and chemical methods such as wave devices. Only 1% of women used insect repellents during pregnancy.

10% of pregnant women used outdoor insecticides, such as in gardens or vegetable plots and yards with plants: 9% every month, 14% every 2-3 months, 20% three times a year and 57% occasionally.

"These results are significant because they enable this information to be used to come up with preventive measures, especially at vulnerable stages of life," Llop affirms.

The less educated, the more pesticides

"Multiparous women, born in Spain, with a lower level of education, who have a garden, whose residence is near crops, and/or from Sabadell or Valencia are the most likely to use household pesticides," Llop asserts.

The use of these pesticides continued during their offspring's first year of life, although 20% of the women stopped using them. Sprays were the method that the participants were most likely to stop using in their bedrooms: 53% during pregnancy and 26% during infancy. In contrast, the use of the electric device remained constant.

Exposure routes

The main ways of being exposed to these substances are inhalation, skin contact and unintentional ingestion. In babies and children, ingestion of contaminated dust in the house is the most significant route of exposure to pesticides in the home.

The authors attribute this to babies spending more time at home and in general wearing fewer clothes than adults. In addition, their breathing zones are closer to the ground, where pesticide residue levels can be higher, and they are more likely to have close contact with plants, grass and other surfaces.

"Fetuses and children are especially vulnerable to pesticide exposure because their detoxification mechanisms and immune systems are not fully developed," Llop concludes.

As G8 wraps up, Cameron sends surprising tweet

ENNISKILLEN, Northern Ireland (AP) ? Well, that was close. Or was it? Shortly after wrapping up one of the most peaceful Group of Eight summits in recent memory, Prime Minister David Cameron let a cat out of the bag.

"Now #G8UK is over I can reveal a bomb was found in Lough Erne," he posted on Twitter. "It was American from WW2. Apparently they had a practice mortar range here!"

Not to worry, however. Northern Ireland police mounted a massive security operation to protect the Loch Erne resort west of Enniskillen involving thousands of officers, restricted airspace and contingencies for protesters. While the security appeared aimed at more modern threats, it clearly paid off.

Police in Northern Ireland confirmed that "during ongoing checks" ahead of the G-8, a suspicious item was discovered on June 12, which later was confirmed to be military ordnance from WWII.

While Dad was off deep in talks of pressing world affairs, presidential daughters Malia and Sasha Obama joined their mom for lunch with Irish rock star Bono.

Hundreds of onlookers had gathered by the time Bono and wife Ali Hewson arrived at the U2 frontman's favored local pub, Finnegan's, in the exclusive Dublin suburb of Dalkey. "I thought this was supposed to be secret," the singer said to the crowd. The spectators may have been tipped off by the U.S. flag flying outside and the restaurant closed to the public amid tight security.

The Obamas dined on fish and chips, natch, with cookies and tea for dessert. "We talked about everything and nothing," said Bono, who is well known to world leaders as an anti-poverty campaigner. "It was a family lunch."

Earlier Tuesday, the Obama ladies had a private guided tour of the Wicklow Mountains National Park south of Dublin. The sun was shining, but the heat brought swarms of unwelcome visitors ? swarming flies called "midges" that forced 12-year-old Sasha to flail her arms as she toured monastic ruins.

But the flies didn't dampen her spirit. Sasha closed the door to the ruins of a 1,500-year-old church, then turned to 14-year-old Malia and the first lady for a high-five.

Cameron has been pushing three T's throughout the G-8 summit in Northern Ireland ? tax, trade and transparency.

He might've tacked on one more as he closed out the gathering of world leaders, making a hard sell for tourism to rejuvenate Northern Ireland's economy.

Cameron acknowledged that many people had a negative impression of Northern Ireland after the country's divisions and struggles. He said that he'd had many goals for the summit ? and improving the image of Northern Ireland was one of them through a bit of free advertising.

You couldn't put a value on the "infomercial" that was the G-8 summit, he told reporters. He boasted that all his fellow G-8 leaders were impressed by their meeting site.

"It's only when you come and see it for yourself that you just see what a magnificent part of the United Kingdom this is," he said.

Cameron isn't the only one hoping that the free advertising pays off. The Loch Erne resort where he spoke went bankrupt in 2011.

___

While Russian President Vladimir Putin might be more prone to pose for sporting pictures, it appears Cameron might have one-upped him ? if anyone can find the evidence.

Cameron told reporters he'd gone for a dip in Loch Erne, saying a swim in the chilly waters was a good way to prepare for a day of tough negotiations.

"It certainly wakes you up in the morning and gets you going for a hard day of chairing these meetings," he told a press conference.

The prime minister's spokesman described the experience as "brisk" in earlier remarks to reporters. Temperatures around Loch Erne were in the low 60s ? but felt much chillier.

Key concepts
Microwave Radiation
Heat
Chemical Polarity
Dipole Rotation

Introduction
Ever wonder how a microwave oven cooks your food? A microwave uses?you guessed it!?microwaves, a form of high-frequency electromagnetic radiation. Think radio waves, just with a much shorter wavelength. Here's the cool thing about microwaves: They're absorbed by certain kinds of matter, whereas other kinds are left alone. In this activity, we'll try cooking up some foamy soap in order to illustrate how microwave radiation influences different types of matter.

Background
Soap is a handy combination of chemicals that do some very cool things when you use it. Soap molecules have both a polar and a nonpolar part. What' is polarity? A molecule is described as polar when it has two or more areas of different electrical charges. A water molecule is a perfect example: it has a positive pole created by the positive charge its oxygen atom and a negative pole created by the negative charges of its two hydrogen atoms. By having a polar and a nonpolar part, soap can bind to both water and dirt. This is what makes it such an effective cleanser!

Microwave ovens work by causing molecules that have two opposing poles to spin rapidly. Because of their polarity, molecules like water will constantly align themselves with a magnetic field they're subjected to. Microwave radiation creates a magnetic field that oscillates?which means that the field is constantly changing its orientation (direction the positive and negative charges face). Those shifts make polar molecules like water start spinning as they try to keep up with the changing charges. As the molecules spin, they generate heat. This process is known as dipole rotation. ("Dipole" simply means "having two poles.")

Have you ever used a microwave to boil water and found yourself wondering why the air in the microwave doesn't get hot like the air in a conventional oven? Microwave radiation causes water molecules go nuts, but the air itself isn't directly heated because its molecules aren't as polar as the molecules that make up water. This help explains why you can't make a pie's crust crispy in the microwave (due to its less polar contents), but it's easy to burn one to oblivion in a conventional oven! Polarity also explains why many plastics, glasses and ceramics are considered "microwave safe"?their molecules in these substances aren't very polar, so they aren't as disturbed by the magnetic fields shifting.

Materials
? One bar Ivory brand soap
? One bar Dial soap
? Two paper plates
? Microwave

Preparation
? Note the weight of each bar of soap, which should be written on the packages.
? Unwrap each bar.
? Place each on a paper plate, noting which one is which.

Procedure
? Microwave the Ivory soap for two minutes, carefully observing it during the whole time. What happens to the soap? Why do you think this might occur??
? Remove the plate with the soap from the microwave. Use caution, as it may be hot.
? Microwave the Dial soap for two minutes, carefully observing. Does this soap react differently than the first one? Why do you think this might be?
? Again, be careful when removing the heated plate.
? Extra: Before microwaving, weigh each bar of soap. Which is heavier? If one is heavier than the other, what do you think accounts for this difference, besides size? Do you think this might help to explain what we saw when we "cooked" the soap bars in the microwave?
