Chronic obstructive pulmonary disease (COPD) is persistent narrowing (blocking, or obstruction) of the airways occurring with emphysema, chronic obstructive bronchitis, or both disorders. Worldwide, the number of people with COPD is increasing. Factors contributing to COPD include an increase in smoking in many developing countries and, throughout the world, exposure to toxins in biomass fuels […]

Universe is expanding faster than once thought The universe’s expansion rate is faster than previously believed. Researchers used the Hubble Space Telescope and observations by the Araucaria Project to determine that the universe is expanding roughly 10% faster than earlier estimates. Space.com Exploring the neuropeptide behind stress-eating weight gain Stress eating may result in greater […]

In 1873, the microscopist Ernst Abbe stipulated a physical limit for the maximum resolution of traditional optical microscopy: 0.2 micrometers, or 200 nanometers (the shortest wavelength for visible light, the extreme limit of violet). This meant that scientists could distinguish whole cells, as well as some parts of the cell called organelles. However, they would […]

On April 10 th 2019, the Event Horizon Telescope project released the first image ever of a black hole. Five simultaneous press conferences, in Brussels, Taipei, Santiago de Chile, Tokyo and Washington were broadcast live, staging a global media event for astrophysics. Besides the inevitable memes in the so-called social media, more serious press outlets […]

I n a recent article in the Journal of Economic Perspectives, three economists from the British Macroprudential Strategy and Support Division and one member of the Financial Policy committee of the Bank of England analyze whether macroprudential regulation could prevent a rerun of the last crisis (Aikman et al ., 2019 ). To address this […]

Researchers create computers in human cells The human body’s similarity to a computer inspired researchers at ETH Zurich to use CRISPR gene editing to build dual-core processors in human cells. The development could lead to the creation of biocomputers to diagnose and treat diseases. New Atlas Brain cells linked to sleep co-opted by general anesthesia […]

On 8 October 2013, following the discovery at CERN’s Large Hadron Collider of a new particle that appeared to be the long-sought Higgs boson predicted by the theory, it was announced that Peter Higgs and François Englert had been awarded the 2013 Nobel Prize in Physics. But they were the survivors of the bunch of […]

In the last two decades, the easiness in the obtaining of genetic information from patient biological samples, together with the advanced knowledge on the physiological consequences of patient genetic alterations, has transformed the daily clinical practice in our hospitals. As a result, the current use of the precision medicine concept, as disseminated today in the […]

In the past entries we have examined three types of ‘abnormal’ psychic experiences that have surely had an important role in the creation and diffusion of the idea of an ‘immaterial soul’ that contains our personal identity, and that can be ‘separated’ from our physical bodies, obviously including the possibility of surviving the biological death […]

Massive Mars dust storm could offer clues to planet’s dryness The ExoMars Trace Gas Orbiter’s observations of the massive dust storm that enveloped Mars last year may help researchers learn more about what happened to the planet’s water. Understanding how such atmospheric events form could provide clues about the history of water on Mars, says […]
