Challenge fun: The spiral of Ulam

The math is really fascinating. There is conjecture not proven, as in the case of the numbers of Collatz (or wonderful), or, assumptions that will eventually be “proved” to brute-force, enumerating all the possible cases, as in the famous theorem of the four colors. Well, here we’ll talk about the so-called “spiral of Ulam” and…

Discover novel way to convert sunlight into fuel

Photosynthesis is the process used by plants to convert Sunlight into energy. The oxygen that is produced as a by-product of photosynthesis is when the water absorbed by the plant is divided. This is one of the most important reactions on the planet because it is the main source of almost all the oxygen that…

Optogenetics: Controlling neurons with light

The field of optogenetics may not be familiar to many people, but this technology allows genetically modified cells, in living tissue, be controlled with light beams. It seeks to understand how the brain works in neuronal disorders such as Alzheimer’s disease, among others. An algorithm to detect Fake News, better than human beings In the…

The probe InSight of the NASA already half way to Mars

The ship InSight means “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport“, which can already give us an idea of what is intended to investigate the probe. You are expected to arrive on November 26 to study the deep interior of the red planet. The spacecraft has covered 227 million kilometers since its launch,…

Planets with water may be more common than expected

In 1992, it was discovered exoplanets orbiting other stars, and thanks to instruments like the Space Telescope Kepler and the esa Gaia mission, will have found planets that could harbor potentially life as we know it on Earth. An interesting new assessment of these exoplanets indicate that many of these could contain more than 50%…

Can a computer write like Shakespeare?

Scientists of Australia together with colleagues from the University of Toronto, department of English, have designed an algorithm to write poetry that follows the rules of rhythm and measure. To test their results, the researchers asked people in line if they could distinguish between the verses written by the software and by human beings. The…

Creates a new award in the ACM in honor of Chuck Thacker

Charles P. Thacker, who died in June 2017 at the age of 74 years, and known as “Chuck”, was a member of the Research Center in Palo Alto, Xerox. He also worked at the Research Center of DEC (Digital Equipment Corporation). In 1997 he was recruited by Microsoft to support the launch of the research…

The telescope Kepler is back to sending information

Kepler has been “snoozing” for four weeks, looking to save fuel that is now defined in a very low level and the mission team wants the probe to be able to have enough fuel to orient its antenna toward Earth to send all the data that is still collected. What is the coldest place in…
