1 New researches has determined that submarine Internet cables could be used to detect earthquake potentials.
To use a telecommunication cable as a seismic sensor, the researchers inject the beam of a laser into one end of the optical fiber and monitor the light coming out of the other end. When a seismic wave shakes the cable, it distorts the light that passes through it.
By comparing the original laser signal with the light coming out of the cable, researchers could determine how much the beam has been deformed along the way and deduce the power of the seismic shock.
2 A new study suggests using the oxygen deficiency of localized cancer cells at the center of growing tumors to eliminate them.
At the center of the most resistant tumors lie cells surviving with very little oxygen, thanks to their ability to capture aspartate in their environment. A new strategy blocking this ability could overcome.
According to the researchers, a mixing treatment for parts of a tumor that are well supplied with oxygen and an aspartate blocker for the rest could increase the chances of remission of patients.
3 Tobacco, alcohol, poor diet: a French study reveals that 40% of cancers could be preventable.
Of the 346,000 cases of cancer diagnosed in 2015 among people aged 30 and over, 142,000 could have been avoided if the entire population had not been exposed to the risk factors studied, or if its exposure had been limited.
Cancer is the leading cause of death in France, in front of cardiovascular diseases. “Too few French people are aware of the risks they take,” recalled Agnès Buzyn, Minister of Health, in March this year.
