This is Saturn’s Moon – the largest moon of Saturn, the only moon known to have a dense atmosphere and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found – and these are just a few of the reasons which make studying it more […]
Subway trains produce airborne dust particles that could damage the lungs, a new study concludes. In the world today it is harder and harder to drive around town or to another town – itt is not cheap, and it takes time. So the subway is a good choice to more and more people. But […]
Pets do more than it may appear for their owners: they teach us a lot about unconditional love, responsibility, death and, of course, pooper scoopers. But aside from that they probably keep a child from developing allergies rather than causing it. This is not yet a scientific certainty, but the idea that pets might […]
It is largely believed that the sabre-toothed cat Smilodon is a fierce, strong and very dangerous predator. Along side the Tyrannosaurus rex it is regarded as a nearly flawless killing machine. The upper canines which are built like knives support that theory. But an Australian study, published recently in the US Proceedings of the […]
Basic paleoclimatology and one a little more There have been many climatic shifts throughout the geologic period of our time. The abrupt climate change events that occurred thousands of years ago are very important to us because they took place closer to this day and so there is a greater chance of repeatability. We […]
Those bursts are from magnetars. You may have some idea about what a white dwarf is, or a black hole or even a pulsar, but what are magnetars? Magnetars are neutron stars with an extremely powerful magnetic field; their decay powers the emission of copious amounts of high-energy electromagnetic radiation, particularly X-rays and gamma-rays. They pack […]
Global warming is a hot topic everywhere in the world, and probably have ourselves to blame for that. The careless use of resources combined with greed and lack of respect for mother earth could be what leads to our demise. The signs are everywhere but at first they were more obvious in the oceans. […]
Homo floresiensis (“Man of Flores”, nicknamed Hobbit) is the name for what may be a species in the genus Homo, remarkable for its small body, small brain, and survival until relatively recent times. It is a 3-foot-tall, 18,000-year-old hominin skeleton with no chin and some other strange and less obvious features. It is believed […]
Carbon nanotubes (CNTs) are allotropes of carbon. Their strength and flexibility makes them useful in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering. They are also used in concrete where they increase the tensile strength, and halt crack propagation in elevators, bridges, circuits, magnets, transistors, and they […]
