A leading US pediatrics group has recommended that drug-testing in school should not be adopted to prevent young people from experimenting with illegal substances. The American Academy of Pediatrics (AAP) in a policy statement released on Monday said that it clearly opposes randomly drug testing-students because there is not enough evidence to show that the process is effective.

They said that random-testing can also harm relationships between students and their schools. It is also a possible policy breach, the group said.

The Supreme Court nearly 15 years ago established the legality for school-based drug testing for students. Supporters of the practice said that random drug testing in schools discourages students from using drugs.

A new study has revealed that daily coffee intake helps to cut the cancer causing effects of alcohol. The study was conducted by researchers of American Institute for Cancer Research and World Cancer Research Fund (WCRF).

They worked together to determine the cause and prevention of hepatic cancer and performed the most in-depth review of research on influences of diet, exercise, and lifestyle on liver cancer.

The researchers analyzed global studies on cancer and how it stems and prepared a report after examining 34 studies that involved over 8.2 million people and over 24,500 cases of liver cancer.

Bald eagles could find a home in New York, according to scientists. A wildlife scientist said that he had his eye on Fordham Road. He found eagle-friendly habitat that was created by the New York Botanical Garden and the Bronx Zoo.

Dan Rosenblatt, head of wildlife diversity at the New York Department of Environmental Conservation, said, "It is one of the few areas where you can actually get into some denser tree stands. They are looking for taller, more mature trees that are surrounded by continuous canopy".

A research team has found that seals off the coast of South Africa were attacking and eating sharks of the region. According to the team, they found that even the largest sharks have been fending off these seal attacks.

The team led by great white shark expert Chris Fallows found that the seals have not only added shark meat into their diets, but they have indicated that of the food chain in the open ocean could be different than scientists originally thought.

According to researchers of the team, they caught seals attacking and even eating sharks in December of 2012. At that time, the researcher Chris Fallows was about 20 nautical miles off the southwest shores of Cape Point.

A group of biohackers has tested a special liquid by injecting into the eyeballs of a volunteer that provided him night vision. In the injection, the liquid used was Chlorin e6 (or Ce6), chlorophyll analog, which is found in deep-sea fish known for having light-amplifying properties. The liquid was put into volunteer biochemist Gabriel Licina's eyes.

Licina said, "To me, it was a quick, greenish-black blur across my vision, and then it dissolved into my eyes". The experiment was successful and then after an hour, he was taken out in a dark field. He was made to perform a number of performance tasks in order to tests his night-vision.

Angelia Jolie, 39, announced that she has got her ovaries removed as a way to ovarian cancer.

The mother of six in a powerful op-ed for the New York Times wrote, "I feel feminine, and grounded in the choices I am making for myself and my family. I know my children will never have to say, Mom died of ovarian cancer".

Last week, Jolie underwent a laparoscopic bilateral salpingo-oophorectomy to remove her ovaries and fallopian tubes.

Op-ed by Jolie won huge praise from oncologists and health experts for bringing a number of sensitive issues into the public discussion. But it also raised several questions about the complex decision-making process faced by women at risk of ovarian cancer.
