“Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying” (Arthur C. Clarke)
Life on Earth is a common thing. Life on clouds and in water looks interesting. And life on places other than the Earth (extraterrestrial life) looks…ummmm…possible. In this article, I will try to note some information ranging from hypothesis to scientific information related to the life on places other than Earth.

Growing with time and becoming old is a common phenomenon. Every person grows older with time, but some people may have the wish to grow old faster. So, this article is for those people. On the contrary, if you want to feel young and good, do the opposite as mentioned in this article. Continue reading How to feel older and/or worse?→
A new study published in PLOS Computational Biology shows that genes associated with hereditary diseases occur throughout the human body.
The study, by Esti Yeger-Lotem et al., used network biology to model the interactions between proteins associated with diseases such as Parkinson’s in different tissues. Using these networks, they show that proteins carrying the disease are found throughout the body.
In tissues vulnerable to hereditary diseases, the networked proteins had unique interactions relevant for the mechanism of the disease. Disease causing genes tend to be more highly expressed. The authors demonstrated through several examples that tissue-specific protein interaction can highlight disease mechanisms, and thus, owing to their small number, provide a powerful filter for interrogating the origins of disease.
These results offer a powerful filter that can enhance the search for new therapeutic targets for many hereditary diseases.

New analysis reveals relationship between Siberian, North American languages.
Evolutionary analysis applied to the relationship between North American and Central Siberian languages may indicate that people moved out from the Bering Land Bridge, with some migrating back to central Asia and others into North America, according to a paper published in the open-access journal PLOS ONE on March 12, 2014 by Mark Sicoli, from Georgetown University and Gary Holton from University of Alaska Fairbanks.
Genetic sequencing exposes diversity of microbial biodiversity in buildings.
The location, connectedness, and human use patterns in a building may influence the types of bacteria they house, according to a study published in PLOS ONE on January 29, 2014 by Steven Kembel from the University of Québec in Montréal, Canada and colleagues.
Humans spend a majority of their time in buildings, which have their own ecosystems of microorganisms. Microbes living in and on buildings or people may play a critical role in human health and wellbeing. To understand how design choices and human use influence the bacteria in the building, researchers collected microbiological, architectural, and environmental data in 155 rooms in a 4- story multiuse classroom and office building on the University of Oregon campus. They used filtered vacuum cleaners to collect dust in offices, classrooms, hallways, bathrooms, and storage closets and genetically sequenced the bacteria.
