Molar size is based on a model, called the inhibitory cascade, which tells how the size of a tooth gets affected by the tooth next to it. By considering this factor, researchers studying prehistoric human teeth have discovered that human evolution wasn’t as complex as previously thought.

The debate between researchers and doubters on evolution of our third molars has reached a crescendo many times in the past. Now, a study by evolutionary biologist Alistair Evans of Monash University in Australia and other researchers has been offering explanation which suggests evolution of human teeth is simple.

Not serious about climate change and its impact on human life? Consider the startling findings of a paper published February 24 in the journal Nature Climate Change, which could push you to reconsider your viewpoint. The study has claimed that as the planet has been warming, earthly objects such as trees, plants, fish and other natural resources have been constantly shifting their base towards the poles, in the direction of higher elevations and deeper into the seas.

The study was conducted by a team of researchers led by Eli Fenichel, an assistant professor at the Yale School of Forestry & Environmental Studies, who cited the example of fish saying money was bound to flow in places wherever the marine life migrated.

A latest study has suggested that the viability or squishiness of a fertilized egg indicates whether the IVF is going to be successful or not.

Stanford University researchers, who carried out the test, checked out the rigidity of hour-old fertilized egg as a genuine way for physicians to select the best embryos during in vitro fertilization.

The researchers reached a conclusion that the success of IVF lies in the feasibility of the fertilized egg. The study has appeared in the journal Nature Communications.

A family of three, including a stage-four throat cancer patient, his wife and seven-year-old son, were ready for a flight from Bellingham, Washington, to the Phoenix area for a vacation when suddenly the boy fell ill and plane authorities removed the three from flight, which was applauded by fellow passengers. The incident hurt the sentiments of the family and also this trip would have been one of the last memories of son with his father.

Christina Alvarado, whose son suffered an attack from being closer to dog as he might be having dog allergy, took on to Facebook to describe her reaction. The family was taken off a Mondayflight.

President Obama’s Precision Medicine Initiative after its success has raised debate on whether the data collected by it will belong to consumer or the organization. Precision Medicine Initiative has been developed to collect genetic data on one million American volunteers so that scientists can develop drugs and treatments tailored to individual patient.

“I would like to think that if somebody does a test on me or my genes, then that’s mine, but that’s not always how we define these issues,” said President Obama on Thursday during a White House forum on the major biomedical research initiative he began last year. The Department of Health and Human Services on Thursday suggested that patients should have access to their medical records, including genomic testing results.

Talking about the Zika virus, some medical professionals have said that Brazil and international health officials have taken the decision too early to declare an association between the mosquito-borne virus and the rise in birth defects.

Some have even argued that the Brazilian government has been irresponsible on the issue, considering that the link hasn’t been scientifically proven between Zika and the birth defect, called microcephaly, which causes infants to take birth with abnormally tiny heads.
