Ecothermic animals depend on external sources for their body heat because they lack the ability to retain the heat generated by their own metabolism. So when it's cold outside, the temperature of these so-called "cold blooded" creatures drops and their metabolism slows down. When it's hot, the opposite happens.
Keeping pets is beneficial in many ways, and anxiety relief symptoms are at the top of the list. There are many ways they help with mental health issues, and sometimes it's as simple as providing companionship. An animal can usually help in this way simply by being present.
There has been a lot of talk about climate change for years, but for most people it is still an abstract concept. This is because most of us have been spared its most devastating consequences.In a manifestation of a warming planet, billions of people could soon be exposed to such high levels of heat than spending longer periods outdoors. during the sweltering summer months it could prove fatal.
The owl is a night bird that we seldom have the privilege of seeing. As we do not see it, we do not know its habits ... for example, a family of owls can capture more than a hundred rats and mice a week.One way to identify them, even if we do not see them, is when we observe a cluster in a corner of what looked like feces from some wild animal.
On the Internet you will find many recipes for homemade plasticine. This is an adaptation that is made totally cold totally. Neither cooking nor hot water. It takes minutes and kids can play with it right away. In addition, it is a 100% biodegradable plasticine.Another advantage is that you can make it more or less soft according to your preference, simply by adding a little more oil.
Current and planned efforts to reduce waste will reduce the volume of plastics by only about 7, say the researchers. Plastic waste flowing into the oceans is expected to triple in volume over the next 20 years, while efforts to halt plastics. Tidal waves have so far barely made a dent in the waste tsunami, according to research.
The loss of sea ice linked to climate change is pushing polar bears to the brink of extinction. Even if we limited global warming now, most bear subgroups would still be lost. Climate change is starving polar bears, according to a study published June 21.
Rock dust that spreads over the planet's agricultural fields may be a climate solution with the potential to remove up to two billion tons of carbon dioxide (CO2) from the atmosphere, according to British researchers. That's more than industries. global aviation and shipping combined, or about half of Europe's current emissions.
The bad thing about solar panels is that they are quite useful during the day when the sun is shining, but they are quite useless at night, in the dark. But now, that doesn't have to be the case: A new solar panel design works even at night, according to an article published by Jeremy Munday, a professor in the UC Davis Department of Electrical and Computer Engineering.
One study claims hummingbirds can order things in sequence, but researchers say it doesn't confirm that they can count. Hummingbirds are not only bright in appearance but also in brain, apparently with new research suggesting that small creatures are capable of understanding a numerical concept of order.
Many household chores such as cooking or cleaning have historically been handmade, each in its own way and in its own time reproducing the recipes of the grandmother or the teachings of the parents. However, some household chores get repetitive, monotonous, and quite tedious. For them, the time has come to have advanced technological devices such as "robots".
Researcher Alvise Vianello analyzed foreign materials found in soil, drinking water, oceans, sewage, and air. Vianello, who studies microplastic contamination at Aalborg University in Denmark, looked at computer screens showing the machines' readouts.
The unique species classification system could end centuries of disagreement and enhance global efforts to address biodiversity loss.A plan to create the first universally recognized species list on Earth has raised hopes of ending centuries of disagreements and confusion about how to classify the world's life library.
One of the lessons that the current coronavirus pandemic has taught us is that we rely on electronic devices more than ever, especially during prolonged periods of self-isolation. Smartphones, laptops, televisions, e-readers, refrigerators, air conditioners have all been extremely helpful.
A comprehensive study of the world's plant species has led researchers to a troubling conclusion: In the tropics, sometime in the next 50 years, it is likely to get too hot for seeds to germinate. That's according to one team. from the University of New South Wales (UNSW) in Australia, led by Alexander T.
The animals were exploited from puppies for eight years in a circus in Guatemala. The reaction of the animals was surprising: The experts affirmed that both managed to endure abuse for eight years for the simple reason of having formed an inseparable pair, taking care of each other and keeping company.
The result of the joint work of master craftsmen from Nacimiento and engineers from Germany is this equipment that reproduces music in high fidelity. A speaker handcrafted in clay with German audio technology. This is Mapuguaquén, an innovative product that emerged in the Bío Bío region.
New research finds that large numbers of small marine animals are seriously injured or killed at higher rates than previously thought.The danger to whales and other large marine mammals from the propellers and bows of ocean vessels has been recognized for a long time.
A growing movement for sustainable agriculture in the Brazilian Amazon has taken on a new urgency with the coronavirus pandemic. Cumaru trees could have been planted elsewhere in this Amazon reserve, where they had a better chance of flourishing. Instead, they were planted in rough, sandy soil in the dry savanna that breaks through the forest.
The biotech industry in the United States appears to be conspiring to overcome public rejection of genetic engineering. What they are doing is trying to promote it as a way to save forests. Researchers have manipulated the genetic material of chestnut trees so that the tree species is resistant to the disease.
Researchers from the Basque Country and Italy have manufactured a battery with an indium arsenide core and aluminum superconductors at its poles that may be key to some quantum technologies. It generates a supercurrent that is not induced by a voltage, as in classic batteries, but by a phase difference in the quantum circuit.
