confirmation of a disappearing star, search for failed supernovae


"The researchers used new observations made with HST, shown above, which shows that N6946-BH1 is no longer there in the visible spectrum, but a faint signal in the near-infrared is present.

Based on the data and models, the scientists believe the data points toward the formation of a black hole, with the thermal emission being created by accretion material entering the black hole."

Maybe tape a note on ceiling with " I A D" on it to remind yourself as you drift off again.

"The MILD technique works on what we call 'prospective memory' - that is, your ability to remember to do things in the future. By repeating a phrase that you will remember you're dreaming, it forms an intention in your mind that you will, in fact, remember that you are dreaming, leading to a lucid dream,"

  1. reality testing - which involves checking your environment several times a day to see whether or not you're dreaming.

  2. wake back to bed - waking up after five hours, staying awake for a short period, then going back to sleep in order to enter a REM sleep period, in which dreams are more likely to occur.

  3. MILD (mnemonic induction of lucid dreams) - which involves waking up after five hours of sleep and then developing the intention to remember that you are dreaming before returning to sleep, by repeating the phrase: "The next time I'm dreaming, I will remember that I'm dreaming." You also imagine yourself in a lucid dream.

Suicide molecules kill any cancer cell (in mice)

"Peter found that a large number of these small RNAs derived from certain genes did not, as expected, only suppress the gene they were designed against. They also killed all cancer cells. His team discovered these special sequences are distributed throughout the human genome, embedded in multiple genes as shown in the study in Cell Cycle.

When converted to siRNAs, these sequences all act as highly trained super assassins. They kill the cells by simultaneously eliminating the genes required for cell survival. By taking out these survivor genes, the assassin molecule activates multiple death cell pathways in parallel."

Peace Processes and Durable Returns

" What the Balkans can teach other states in conflict

Research at the University of Kent into how areas like the Balkans have developed ways to address the challenges of their past -- including ethnic cleansing -- offers a toolkit for others facing similar conflict"

Chaos reigns even in simple electronics

"Chaotic behavior is so complex that to this day there are no methods to effectively design electronic circuits of this type." Even in electronic circuits containing only one or two transistors, chaos is ubiquitous! The predictable and always the same reactions of electronic devices that we all use on an everyday basis do not reflect the nature of electronics but the efforts of designers"



Of particular interest was one of the found oscillators, which generated voltage spikes resembling stimuli typical for neurons. The similarity of impulses was striking here, but not complete.

"Our artificial neuron analogue proved to be much faster than its biological counterpart: pulses were produced thousands of times more often! If it were not for the lack of criticality and multi-fractality, the speed of operation of this circuit would justify talking about an electronic super-neuron. Perhaps such a circuit exists, only we have not found it yet. At the moment, we have to be satisfied with our 'almost super-neuron'," comments Dr. Minati, with a smile.

Physically active white men at high risk for plaque buildup in arteries


"When these findings were stratified by race and gender, they found that white men were at the highest risk-they were 86 percent more likely to have CAC. There was no higher odds of CAC for black participants who exercised at this level, and while there was a similar trend for white women it was not statistically significant."

"High levels of exercise over time may cause stress on the arteries leading to higher CAC," said Rana, "however this plaque buildup may well be of the more stable kind, and thus less likely to rupture and causes heart attack, which was not evaluated in this study."

Glucosamine dampens the brain hyperexcitability seen in seizures or epilepsy


Since neural excitability in the hippocampus is a key feature of seizures and epilepsy, they hypothesized that acutely increasing protein O-GlcNAcylation might dampen the pathological hyperexcitability associated with these brain disorders.

NIST cautions of using bayes for weighting in legal forensics


"Bayesian theory does not support using an expert's opinion, even when expressed numerically, as a universal weight of evidence. Among different ways of presenting information, it has not been shown that LR is most appropriate."
