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.

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.
“We started this work more than a decade ago, with a kind-of crazy hypothesis that there might be something in the blood that influences tissue repair with age,” says Amy Wagers, a researcher at the Harvard Stem Cell Institute, who is a coauthor on two of the three new works. (MIT Technology Review has covered Wagers’s work in the past, in “Young Blood Reverses Signs of Aging in Old Mice”; however, the study in question in that story was later retracted due to questions over the role of particular cells: “Research on Rejuvenating Effect of Young Blood Retracted.”) Last year, Wagers had reported that linking the circulatory systems of an older mouse and a younger mouse at the hip helped improve the appearance and function of the weakened, enlarged hearts of older mice. The team then screened the blood of young and old mice to look for differences and found that older mice had less of a protein growth factor called GDF11, which is also found in human blood.
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.
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.

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.

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 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.
The return after a century to the global constancy of c of the early Einstein implies that man-made black holes – which CERN tries to produce in its soon to be re-started particle collider – are different: They are undetectable to CERN’s detectors. This fact renders the experiment strictly speaking unscientific. Most important, however: if but one specimen of the invisible hoped-for objects is slow enough not to fly away into outer space, it is going to grow exponentially inside earth to turn the planet into a 2-cm black hole after a silent period of a few years in accordance with the laws of exponential growth.
As long as CERN is unable to publicly contradict this scenario in an update of its famous 6 years old Safety Report, they cannot re-start the Large Hadron Collider on logical grounds.
It all boils down to the question: “Who of the two Einsteins – the early one or the 2 ½ years older one – was right?”
