Maternal and paternal stress have been proved to be critical aspects of off-spring brain development. High levels of stress on pregnant mothers can alter both placental and embryonic gene expression patterns, misprogramming the brain of the newborn towards psychiatric disorders such as anxiety or depression. At the same level, paternal stress alters microRNAs and other […]
Flu outbreaks likely influenced by city size, crowding A city itself influences the contours of its flu season – whether flu cases rise to a wintertime peak or plateau from fall to spring. ScienceNews Review shows vitamin D does not prevent falls, fractures A review of data from 81 studies found vitamin D supplements do […]
“What would happen if we could arrange the atoms one by one the way we want them?” Richard Feynman Fabrication of matter atom by atom remains a long-standing dream and ultimate goal of nanotechnology, following the famous challenge by Feynman 58 years ago. For 30 years, the atom-by-atom fabrication remained the province of visionary thinking […]
I’m a man slowly sliding into the old age. Being a scientist (a simple science worker), this means that for decades I’ve become familiar with the uncomfortable feeling of struggling to adapt to a constant, quick change of everything. In the very beginning of my career, still an undergrad, I joined a lab where my […]

Huge Jurassic-period dinosaur had crouching posture An enormous Jurassic-period dinosaur that walked on all fours with an unusual crouching posture has been described in a new study after its remains were fully unearthed last year. The 200 million-year-old sauropodomorph has been dubbed Ledumahadi mafube, which translates to “a giant thunderclap at dawn.” Live Science Mayan […]
Imagine that we have a conductor or a semiconductor through which a current is flowing. Then we apply a strong transverse magnetic field. As a result, we can measure a potential difference at right angles to both the current and the field caused by the deflection of charge carriers by the field. This effect was […]
Educational attainment, the years a person spends within the education system, generates interest among scientists because statistical analysis shows that there is a relationship between that value and different aspects of life including income when adults, state of health and even life expectancy. Geneticists analyze trends that can explain variations within a population by exploring […]
