Technology has the power to shape our lives completely, but it can also change our bodies in unexpected ways. Recent studies have suggested small spikes that can grow on our skulls, and smartphones can be the culprit for this change.
But do not panic yet.
One critic of the study says he "does not hold water, while another says the paper hypothesis is only speculative. in the journal Scientific Reports. The study found a second life after the BBC published an article "How Modern Life Transforms the Human Skeleton," which cites their work.
CNN reached Shahar and Sayers for comment. Shahar and Cyers said that young people can develop small horns in the back of their skulls, possibly caused by the shift of the head weights from the spine to the muscles at the back of the head and neck. This anatomical characteristic is called an external tip, or EOP.

Possible Cause of This Weight Change? You probably knew him. Researchers suggest that this is due to the poor posture of people moving forward because of the use of the phone and the mobile device.
For their first study, the two researchers have set a threshold of 5 millimeters to record EOP, and consider it an increased EOP if it has exceeded 10 millimeters in length. They found that 41% of participants aged 18 to 30 had an increased EOP in their skulls.
These types of bone branching occur more frequently in the elderly and are considered a normal part of an aging process. However, Shahar and Cyers believe that advances in technology have changed the deadlines for this type of bone growth. Thirty-three percent of participants had bone growth, but it is strange that growth has been found to have diminished with age.
But not all agree with the ideas of the researchers.
John Hawkes, the professor of Villages-Borghese, who is an excellent professor for the Department of Anthropology at the University of Wisconsin-Madison, said that "this study does not feed water."
Hawks notes that the study lacks a scorecard that would offer more detail about their findings, and there are contradictions between the text and
Hawks believes the data presented are not measured in a consistent manner.
"There is no information on the duration or frequency of use of handheld devices in this study, so it is not possible to draw a link between observations of increased GPUs and the use of portable devices," said Dr. Mariana Kersh, assistant professor at Department of Mechanical Sciences and Engineering at the University of Illinois at Urbana-Champaign and Director of the Tissue Biomechanics Laboratory. , "There is definitely no reason and effect proven in this study
" The hypothesis on the role of using handheld devices is only speculative and is not based on any data presented in this study. "
The study did not have a control group, and the X-rays were taken by patients who had to visit a chiropractor with severe neck problems to take x-rays that may not offer the best picture of the general population  "Bone adaptation usually occurs in response to dynamic, repetitive movements that the body is not used to seeing," says Kersch. "The strain on the bone must be large enough (higher than usual) to cause adaptation. With what we know about how bones react of mechanical loading, the change of the stand itself is unlikely to lead to changes in bones, especially within a lifetime other than the hypothetical loads proposed by Shahar and Sayer.
