Matter and Antimatter
Higgs Boson Could Explain Matter’s Dominance over Antimatter A new theory suggests the Higgs field varied in the early universe, offering matter a chance to split off from antimatter February 20, 2015 |By Clara Moskowitz [image: Higgs boson particle tracks in LHC] Computer simulation of particle tracks from an LHC collision that produced a Higgs boson. *CERN* The stars, the planets and you and I could just as easily be made of antimatter as matter, but we are not. Something happened early in the universe’s history to give matter the upper hand, leaving a world of things built f... mais »
Time and Space
Do Time and Space Exist at the Smallest Scales? An artist’s impression of a supermassive black hole. Black holes are rife with paradoxes, but a new theory suggests that they can all be resolved by agreeing that space and time break down at very small scales. Image credit: ESO/M. Kornmesser We’ve come a long way in 13.8 billion years; but despite our impressively extensive understanding of the Universe, there are still a few strings left untied. For one, there is the oft-cited disconnect between general relativity, the physics of the very large, and quantum mechanics, the physics of t... mais »
Dama da Noite
Ao chegar à janela do quarto na noite passada dei com a imagem da Dama da Noite florescendo, coisa que parece ser pouco frequente. A muda original colocamos há mais de dez anos junto ao muro de nosso jardim dos fundos. Ela foi crescendo e se estendendo, somente agora deu flores. A muda nos deu um amigo e cliente que reside em Ivoti, onde ele era proprietário de uma farmácia. Acontece que este amigo é filho do ex-proprietário da Pharmacia Popular de Agudo (na época Distrito de Cachoeira do Sul) adquirida por nosso pai Bôrtolo Achutti em 1939. Lá vivemos até 1942.

DNA Long term data storing
How to store data error-free for millions of years February 16, 2015 [image: fossil data storage] ETH researchers have found an error-free way to store information in the form of DNA, potentially preserving it for millions of years: encapsulate the information-bearing segments of DNA in silica (glass), using an error-correcting information-encoding scheme. Scrolls thousands of years old provide us with a glimpse into long-forgotten cultures and the knowledge of our ancestors. In … more…
cognitive enhancers
An ‘in silico’ method of predicting effectiveness of cognitive enhancers February 17, 2015 [image: pathway activation profile2] The Biogerontology Research Foundation (BGRF) has used gene expression data to evaluate activated or suppressed signaling pathways in tissues or neurons of the mouse brain that has been cognitively enhanced with nootropic drugs. Currently used cognitive enhancers are those that are widely available, rather than optimal for the user, the researchers note. These include drugs … more…

Before memory slips
*Catching Alzheimer’s before Memory Slips* Can a five-minute eye-tracking test warn of disease to come? February 12, 2015 |By Esther Landhuis Several scientists outside the company think the test is promising because, unlike other cognitive batteries, it requires no language or motor skills. *Credit: Vince Alongi/Flickr* Whereas cholesterol levels measured in a routine blood test can serve as a red flag for heart disease, there’s no simple screen for impending Alzheimer’s.
