Scientists have discovered a central hub of brain cells that may put the brakes on a desire to eat, a study in mice shows.
And switching on these neurons can stop feeding immediately, according to the Nature Neurosciences report.
Researchers say the findings may one day contribute to therapies for obesity and anorexia.
Experts say this sheds light on the many complex nerve circuits involved in appetite control.

Can Compounds in Young Blood Fix Aging?

Posted by in category: life extension

By Susan Young Rojahn — MIT Technology Review

Researchers and investors are already dreaming up ways to devise medical treatments based on the near-fantastical findings that the blood of young mice can rejuvenate older mice. In some cases, a single protein found circulating in the blood is sufficient to restore muscle tissue and improve brain activity.

The excitement is spurred by three newly published studies that showed that components of blood from young mice were able to repair damage and improve the function of the muscles and brains of older mice. Previous work from one of the research teams involved has also shown that a specific component of young blood can repair the damaged hearts of older mice.

The Game Theory of Life

Posted by in categories: DNA, genetics

By: Emily Singer — Quanta Magazine

Applying game theory to the behavior of genes provides a new view of natural selection.

In what appears to be the first study of its kind, computer scientists report that an algorithm discovered more than 50 years ago in game theory and now widely used in machine learning is mathematically identical to the equations used to describe the distribution of genes within a population of organisms. Researchers may be able to use the algorithm, which is surprisingly simple and powerful, to better understand how natural selection works and how populations maintain their genetic diversity.

By viewing evolution as a repeated game, in which individual players, in this case genes, try to find a strategy that creates the fittest population, researchers found that evolution values both diversity and fitness.

Physicists Prove Surprising Rule of Threes

Efimov trimers.

More than 40 years after a Soviet nuclear physicist proposed an outlandish theory that trios of particles can arrange themselves in an infinite nesting-doll configuration, experimentalists have reported strong evidence that this bizarre state of matter is real.

In 1970, Vitaly Efimov was manipulating the equations of quantum mechanics in an attempt to calculate the behavior of sets of three particles, such as the protons and neutrons that populate atomic nuclei, when he discovered a law that pertained not only to nuclear ingredients but also, under the right conditions, to any trio of particles in nature.

Buenos Aires new lighting can be monitored and controlled from a browser

The Philips LED lighting can be controlled and monitored using the CityTouch control panel
LED lighting offers a host of benefits for cities, such as reduced energy usage and costs. For Buenos Aires, which is in the process of having its lighting infrastructure upgraded, one of the benefits is the increased level of control it provides. Gizmag took a look at technology being used.

It was announced towards the end of last year that Philips had been selected to replace 91,000 street lights across Buenos Aires with LED lighting. That’s more than 70 percent of the city’s lighting. Philips says that it is the biggest city deployment of its kind. A total of 28,000 lights have now been replaced and are already being controlled remotely.

Promising Early Results on Universal Blood Test for Cancer

Absent an outright cure, it’s thought that early diagnosis of terminal diseases like cancer make treatment more effective and raise the probability of survival. But diagnosis is not always straightforward and often requires costly and invasive tests.

Simple, cheap, and accurate tests looking for the markers of disease may help.

One such method may be a blood test for cancer from University of Bradford researchers. The Lymphocyte Genome Sensitivity (LGS) test observes how DNA in lymphocytes (a type of white blood cell) is damaged under varying intensities of ultraviolet (UV) light.

CERN AND THE EARLY EINSTEIN

Posted by in categories: existential risks, particle physics

CERN bets the planet on the early Einstein having been wrong. Let me explain.

After having founded special relativity in mid-1905, the early Einstein held fast to the speed of light c being a global constant of nature for another 2 ½ years. Only in December of 1907 did Einstein switch to the view that c was only an everywhere locally, but not globally, valid constant of nature.

In 2008, results proving that the early Einstein of 1905 was right started to appear in the scientific literature. For example, quantum electrodynamics combined with the equivalence principle (Schwinger) shows this. Up until now, no counterproof is in the literature.

In light of this renaissance of the early Einstein, a previously noncontroversial policy of the famous CERN consortium turns out to be problematical: their refusal to update the outdated Safety Report of mid-2008. Demanding this update has become a priority issue for everyone who learns about its lack.
