A latest study has suggested that younger siblings could be good for your health. The longitudinal study tracked roughly 700 children throughout the US. The researchers discovered that the kids, who didn’t have a sibling till they were in first grade, have more chances of being obese at that age in comparison to children, who got a sibling in the ages between three and four.

Basically, the birth of a sibling some years into the life of a child was linked to a healthier body mass index (BMI) trajectory for the first child. The study has appeared recently in the journal Pediatrics.

A latest Taiwan study suggested that the birth date of a kid may play a part in determining which children are going to be diagnosed with attention deficit hyperactivity disorder (ADHD) and then can be put on medication for treatment.

The researchers discovered that preschool and school-age children, born in August were more vulnerable to be diagnosed with ADHD and getting medication for the same, in comparison to their peers born in September.

Published on March 10 in The Journal of Pediatrics, the study cleared that the findings aren’t applicable on teens.

In Taiwan, the cutoff birth date for getting into school is August 31, due to which the kids born in August are naturally the youngest ones in their grades, whereas September-born children are usually the oldest.

Xalkori (crizotinib) has been passed by the FDA as a treatment for patients suffering from ROS1-positive metastatic non-small cell lung cancer (NSCLC). The decision has been taken on the basis of the demonstration of substantial effectiveness in a phase 1 study.

It was based on data from 50 patients with ROS1-positive NSCLC wherein 66% was the overall response rate (ORR) with a median time period of response of 18.3 months by independent review.

Firstly a breakthrough therapy designation was given and then the approval arrived nearly 30 days ahead of a deadline decided under the Prescription Drug User Fee Act.

With little food processing and introduction of meat in the diet, ancient humans might have reduced the need for chewing food. With lower count of chews per meal, they were having time for more activities. Also, adding meat played an important role as it had higher nutritional value compared to vegetarian diet.

Human skeletons started changing in notable and puzzling ways when our genus, Homo, got separated from other hominins more than 2.8 million years back. For example, Homo erectus was quite taller and possessed a bigger brain case as compared to the Australopith ancestors.

Environmental groups have long been demanding strict curbs on activities such as oil and gas drilling that has been blamed for decline in the population of greater sage grouse across the American West.

In a latest effort, these groups Thursday sued the Obama administration alleging the sage grouse conservation programme that the government had announced in September last had many loopholes. Filed in the US District Court in Idaho, the lawsuit also claimed that the plan may not prove enough to protect the bird from extinction. Sage grouse is known for its elaborate mating ritual.

Physicists have recently detected a new particle using the Large Hadron Collider (LHC) situated at the CERN facility in Switzerland. The scientists are claiming that this particle might be capable of bringing about a revolution in the field of physics.

The new particle is likely to serve as a sign for the emergence of a new age of physics. If the findings made by the physicists are established, it is likely to uncover a major error in the Standard Model of Physics. Subatomic physics is primarily based on the set of theories of the standard model.
