Genetic response to starvation is passed down to at least three generations


In 1944, the Nazis caused widespread famine in Western Netherlands after they blocked food supplies. A group of pregnant women living in the Netherlands, labouring under starvation conditions imposed by a harsh winter and food embargo, gave birth to relatively small babies. When their children grew up, in relative prosperity, to have children of their own their babies were unexpectedly small. …

Advancements in genetic sequencing has allowed genomic research to flourish. DNA sequencing is now much faster, cheaper and accurate than ever before, and we’re only now beginning to reap the rewards. It’s the first step to a complete understanding of our bodies. The Human Genome Project, once finally completed, mapped and identified all the genes of the human genome. This helps…

Since its advent some 100 years ago, crystallography has become one of the most important processes in chemical research and development. It involves bombarding a material with X-rays to produce a diffraction pattern as they reflect off the sample. The pattern can be used then to directly determine the atomic structure of the crystal. Using this technique, the structure of…

Pluto’s Moon may have harbored underground ocean


The new NASA-funded study showed that if the icy surface of Pluto’s giant moon Charon is cracked, analyzing the fractures could show if the interior was warm and perhaps warm enough to have maintained a subterranean ocean of liquid water. Pluto is the most distant planetoid (no longer a planet, sorry) in the solar system. It’s extremely far from us,…

Glass molecules jam to form fractal wells

Glasses form when their molecules get jammed into fractal "wells," as shown on the right, rather than smooth or slightly rough wells (left). Photo credit: Patrick Charbonneau:

Water is liquid, air is gaseous, but glass? For years at end, glass has perplexed scholars intending on fixing it under a state of matter. Neither liquid, nor solid, explaining glass is a lot harder than some might think. Researchers at Duke University have contributed to solving the puzzle after they performed numerical solutions and found the energy landscapes of glasses…

Monkeys can do math, study proves

It’s long been supposed that monkeys are capable of mental arithmetics, but it was only recently that this was proven for a fact by neuroscientists at the Margaret Livingstone of Harvard Medical School in Boston. The researchers taught three rhesus macaques to identify symbols representing the numbers zero to 25, then when given the choice between two panels, one depicting…

Last week, the story of a German fisherman made front news after he found a message in bottle floating in the Baltic Sea for nearly 101 years. What’s more, despite most of the text written was undecipherable, researchers at the Hamburg Museum were able to find the sender’s name and deliver the message to his grand-daughter. An incredible story, the…

Newly discovered microRNA may help diagnose lung cancer


Researchers at the National Research Foundation of Korea report on Sunday that they have identified a new microRNA molecule that suppresses a gene, which previous research had identified as playing a crucial role in lung cancer development. If the present findings are refined, it may be possible to diagnose lung cancer in the future based on this genetic marker. MicroRNAs…

Once with the discovery and confirmation of the Higgs boson, the Large Hadron Collider in Geneva proved its money worth and garnered international appraise. Despite the LHC is currently shutdown for its periodical maintenance (the restart procedure is well underway, with the particle accelerator expected to become fully operational again in 2015), physicists aren’t slaking. The data gathered from experiments…

Scientists have made great efforts to discover a material that can be used to both absorb and emit light. A fluke may have suffice, since researchers at Nanyang Technological University (NTU) in Singapore discovered by accident a material that can be used to work as a solar panel, harnessing energy from the sun during the day, as well as a…
