Researchers in Israel and Germany develop potential alternative to animal testing

"On top of opposition from animal rights groups, more scientists are claiming that animal studies do not accurately predict the human response to drugs or beauty products, especially ones that are used on a regular basis. At the same time, using human cells for safety testing is not practical because they die after a few days outside of the body."

"To address this challenge, the researchers have created a liver-on-a-chip device, also known as a 3D micro-reactor, which mimics human physiology using nanotech-based optoelectronic sensors."

"When testing Tylenol using the technology’s sensors, the researchers were able to detect small, rapid changes in cellular respiration that have never been observed before – suggesting potential damage at much smaller dosages than had previously been observed. Scientists had long believed that liver damage from acetaminophen only occurs at high doses and in cases of diseased or compromised liver function."

"Yissum, the tech transfer arm of Hebrew University, together with the Fraunhofer Institute, submitted a joint provisional patent application earlier this year and are seeking industry partners to take the liver-on-a-chip to market. The global market for this technology is estimated to be worth $17 billion by 2018."

Surgeons practice on 3D-printed models for kids’ operations

"Surgeons at Boston Children's Hospital started using 3D-printed copies of patients' affected body parts to prepare for procedures last year. Now, that move has helped save the lives of four children aged two months to 16 years old who suffered from life-threatening blood vessel malformation in their brains. Their condition gave ride to distinctive anatomies that one of the hospital's neurosurgeon, Edward Smith, said were really tricky to operate on. So, the doctors used a combination of 3D printing and synthetic resins to conjure up copies of the kids' deformed vessels, along with nearby normal counterparts and surrounding brain anatomy. That gave them the chance to practice extensively beforehand and reduce possible complications on the operating table."

Check Your Body for Skin Cancer with the ABCDEs of Melanoma
Everyone can be at risk of getting skin cancer, but catching it early can make it a lot more treatable. Performing regular skin checks with this method will help you spot trouble early on.

Discarded pet goldfish are multiplying and getting kind of ginormous, officials say

Discarded pet goldfish are multiplying and getting kind of ginormous, officials say

"If you have a goldfish, and you are kind of over that goldfish, to the point where you are now wondering whether it might be best to set that goldfish free, please rethink that decision."

"That's the request from the Alberta government, which is trying to get Canadians to refrain from dumping out their fish tanks into ponds. Because those ponds are filling up with those discarded goldfish, which are getting really, really big in the wild."

"'It's quite a surprise how large we're finding them and the sheer number,' Kate Wilson, aquatic invasive species coordinator at Alberta Environment and Parks, told the broadcaster."

"In one case, the municipality of Wood Buffalo pulled 40 of the domestic fish species from a stormwater pond."

"'That's really scary because it means they're reproducing in the wild, they are getting quite large and they are surviving the winters that far north,' said Wilson."

So if you could not dump your aquariums in lakes or otherwise dispose of your fish in an improper manner, that would be super.

US orders ban on ‘unsafe’ trans-fats

"Trans-fats are unsafe to eat and must be banned from the food supply within three years, US regulators have said."

"The US Food and Drug Administration said partially hydrogenated oils (PHOs), the main source of trans-fats, are not 'generally recognised as safe'."
