Australian scientists said that they have discovered why human beings have not been able to find out signs of alien life. It is quite sad a reason for the ones who wish to meet up with a real-life ET someday.

The paper was published in the journal Astrobiology, this week. The researchers theorized that that alien life forms cold have arisen a number of times in numerous places, but were rapidly snuffed out when acute heating or cooling left their host planets unfit to live in.

Scientists at the University of Calgary and UC Davis suggested that if you have always thought of a zebra’s stripes as offering a kind of camouflaging protection against predators, then you must think again. The study findings have been published on Friday, January 22, in the journal PLOS ONE.

The lead author of the study, Amanda Melin, an assistant professor of biological anthropology at the University of Calgary, Canada, said that the most longstanding theory for zebra striping is crypsis, or camouflaging, but so far the question has been always framed from humans point of view.

The US Centers for Disease Control and Prevention (CDC) and the American Diabetes Association and the American Medical Association (AMA) joined hands to initiate a public education campaign to create awareness regarding pre-diabetes.

One out of every three adults in the US suffers from pre-diabetes, which is a severe health condition that can eventually result in type-2 diabetes, heart attack and stroke. According to the CDC, approximately 29 million people suffer from diabetes, covering almost 9% of the total population.

On Thursday, federal researchers reported that a fatal birth defect has been increasingly seen in maternity wards, and the cause isn’t known so far.

Infants suffering with the defect, known as gastroschisis, take birth with intestines poking out of a hole in the abdominal wall. Other organs, including the stomach and liver, could also be found outside the body when the baby is born.

The Centers for Disease Control and Prevention said that the prevalence of gastroschisis has seen a roughly 30% rise to 4.9 births out of 10,000 during the years from 2006 to 2012, from 3.6 per 10,000 live births from 1995 to 2005.

On Thursday, researchers reported that human papillomavirus (HPV) increases the probability that someone will suffer from head and neck cancer with a minimal sevenfold and could be much more.

HPV is already known to cause head and neck cancer, but this research has shown just how much it affects the vulnerability.

You have a reason to be happy too because the virus can be prevented using a vaccine, and doctor can find who’s at most risk with the help of a mouthwash test.

Dr. Ilir Agalliu along with colleagues at New York’s Albert Einstein College of Medicine analyzed the records of over 96,000 people, who took part in a big medical study.

According to new tests carried out by scientists in New York, initiating the availability of water in cafeterias in schools is likely to have a significant impact in reducing the BMI of students.

Though the decrease was very small, from a statistical point of view, it was quite significant, according to a report published by the researchers of New York University Langone Medical Center. However, the research reveals the possibility of reduction in obesity through the easy availability of water.
