…and we refrain ourselves from doing anything. The reefs and marine creatures are dying slowly but certainly because of human activity – we are pretty well past the point of denying it. There are numerous ways to destroy it, be it through global warming, ocean acidification, overfishing, and so much more; many would say […]
Every once in a while, a disease grows and grows so much that it turns into an epidemic – in other words, an epidemic occurs when new cases of a certain disease, in a given human populationsubstantially exceed what is expected. The epidemic is hard to control and treat. But it is better to prevent than […]
Life emerged and evolved initially in the water – every creature we see today stems from creatures who initially evolved underwater. But even after so much time, there there are many things don’t understand about marine ecosystems, and to be quite honest, the ecosystems we probably know least about are underwater. Researchers from Fisheries and […]
Fruits and vegetables are very important for your health and “Eat your fruits and vegetables” is one most used recommendations for a healthy diet – and for good reason. They help you ward off heart disease and stroke, control blood pressure and cholesterol, prevent some types of cancer, avoid a painful intestinal ailment called […]
Sleep is the state of natural rest observed in the mammals and birds, and in many reptiles, amphibians, and fish. It is very important and is generally characterized by a reduction in voluntary body movement, temporary blindness, decreased reaction to external stimuli, loss of consciousness, a reduction in audio receptivity, an increased rate of anabolism […]
There is still some debate around how life appeared here on Earth and it is hard to find undeniable proof. But the findings from NASA‘s Spitzer Space Telescope suggest that space dust — the same stuff that makes up living creatures and planets — was manufactured in large quantities in the winds of black […]
The number of people that our planet supports is growing fast [later edit: 7th billion baby comes with a warning], and for the diet that every man has there is a land surface which provides his food. Some types of diet require more land, some less; a low-fat vegetarian diet is very efficient and […]
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 […]
