Hormonal birth control failure might be due to genetic mutation The reason hormonal birth control methods aren’t 100% effective, even in compliant patients, may be due to a genetic mutation in some women. Researchers say about 5% of women are genetically predisposed to produce an enzyme that lessens the effectiveness of hormonal birth control. Wired […]

Every year the amount of data produced is of the order of magnitude of the Avogadro’s constant, thus 6.028×1023. This trend is supposed to increase even more in the next future. This implies that more and more special metals will be needed. The point is: what might happen if the resources used for manufacturing common […]
Wildfires are a major problem with a strong impact on human life, property and the environment, Global warming and a legacy of poor management are the forces behind the increase in their occurrence and in their magnitude measured in extension. In 2017, an unusual number of extensive and severe wildfires occurred in many parts of […]
The needs imposed by a globalized society that maintains activity 24 hours a day and 7 days a week are being addressed by increasing working hours and extending work activity into the weekend. Karoshi, which can be translated literally as “overwork death” in Japanese, is occupational sudden mortality. In Asian countries, the risk of karoshi […]
Photo captures merging shock waves made by jets Merging shock waves created by the supersonic speeds of two Air Force jets can be seen for the first time in photos taken by NASA. A plane flying over the two T-38 planes snapped the photos using air-to-air schlieren photographic technology. Live Science Optical laser probe can […]
One of the ultimate goals in surface science is to comprehend the fundamental processes that make that surface reactions need less than a picosecond (10-12 s) to occur. This means understanding what is happening at the scale of femtoseconds, that is, measuring things that take some tens or hundreds of 10-15 seconds to occur. To […]
Chemo-resistance remains a leading cause of mortality in cancer. Two recent discoveries demonstrate that some bacteria strains induce chemo-resistance, and can be targeted to increase the efficacy of therapeutic agents. The emerging relationship between the microorganisms and tumor progression has led many research groups to investigate whether the existence of a particular pattern of bacteria […]
Darwin’s great breakthrough was that of finding the only one explanation of the great variety and complexity we find in the living world, which is compatible with the fact that the matter and energy of which living beings are made of can only do what they do because of purely physical mechanisms. There is only […]
Ocean warming threatens fish populations Warming ocean temperatures due to climate change helped reduce the amount of seafood that could be sustainably caught between 1930 and 2010 by 4.1% worldwide. In some regions, such as the Sea of Japan and the northeast Atlantic, the decline is more dramatic — as much as 35%, researchers say […]
Topological materials have special universal properties, which are protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Topological materials behave like an ordinary insulator in the bulk but have conducting states on their boundaries, i.e., edges or […]
