It is now commonplace to see solar panels on the rooftops of homes and businesses. There are more than a million solar homes in the US alone. But a new generation of see-through solar technology has the potential to also turn the windows of buildings and cars, as well as other glass-coated objects, into electricity generators.
There has been a spate of announcements from major car manufacturers in recent times detailing their plans to electrify their future vehicles. General Motors recently announced its “path to zero emissions” plan which includes the introduction of at least 20 electric vehicles by 2023. They are joining Volvo, Volkswagen, Toyota and others in making such an announcement.
Tsetse flies are widespread in Africa. They feed on blood and are the source of the dreaded sleeping sickness, an infection that can be lethal, damages the nervous system and, in its final stage, causes a dozy state, which gave the disease its name. Sleeping sickness is a real danger for people in tropical Africa, but tsetse flies can also transfer the disease to cattle. This leads to huge losses in milk, meat and manpower. The damage caused by the flies in Africa is estimated to be nearly $5 billion a year.
When was the last time you used a squeegee to remove squashed insects from your windshield? It’s been a while, right? It’s not just you. This is known as the windscreen phenomenon. Scientists and some motorists have long suspected that flying insects are in dramatic decline. New research has confirmed these suspicions.
Plants are a critical part of the Earth’s carbon cycle. They take in carbon dioxide during photosynthesis. Eventually, dead leaves, branches and other materials fall to the ground where bacteria and fungi decompose the materials and release the CO2 back into the atmosphere. This carbon-soil feedback loop is a complicated one that is critical to the overall carbon balance because soils actually contain two to three times more carbon than the atmosphere.
The use of neonicotinoid pesticides or neonics has long been suspected as harmful to bees and a major factor in the widespread decline of honeybee and wild bee populations. A study published in Science last June provided strong evidence that neonics are indeed a real problem for bees.
Microplastics, which are tiny pieces of weathered plastic less than 5 millimeters in diameter, have been accumulating in the oceans for the past 40 years and are now ubiquitous in the marine environment. They are a major threat to many kinds of marine life, including numerous species of birds, turtles, fish, marine mammals and invertebrates who ingest the stuff causing a variety of problems.
The British discount airline EasyJet recently announced a partnership with American company Wright Electric to develop an all-electric commercial airplane that they said could be flying within 10 years. The goal of the partnership is to develop aircraft with a maximum range of 335 miles, which is long enough for many of the European routes that EasyJet flies from its hub in England.
Coral reefs are essential for much of marine life and are the basis of many commercial fisheries. In places from Florida to Australia, they are major tourist attractions. Estimates are that the economic impact of coral reefs is more than $375 billion a year. And apart from all of that, they are some of the most beautiful places on the planet.
Globally, an estimated 4.5 billion people are exposed to particulate air pollution levels that are at least twice that of what the World Health Organization considers safe. But the impact that sustained exposure to air pollution has on a person’s life expectancy has remained a frustratingly unanswered question. That is until now.
A study by the American Association for the Advancement of Science has produced an estimate of the total amount of plastic manufactured worldwide since the 1950s. The researchers then measured that data against statistics on recycling, incineration and discard rates. The results are sobering.
In a study published in the journal Science, researchers from institutions in the United States, South Korea, and China described the development of “twistron” yarns, which are essentially pieces of yarn that produce electricity when they are twisted or stretched.
In discussions of global warming, we often hear about the effects of a 2-degree rise in temperature or a 1-degree rise in temperature. For most of us, such changes seem pretty insignificant. Of course, in our daily lives, a one-degree temperature change is not particularly noticeable. But in the context of climate change, we are talking about a change in average temperature over time, not the temperature on a particular day or at a particular time.
As carbon dioxide levels in the atmosphere continue to rise, it may be that clean energy technologies, electric cars, and other methods of reducing emissions may not be enough. Carbon sequestration – sucking carbon out of the atmosphere – is seen by many as a crucial part of the solution.
There is more and more interest in electric cars and, based on the half million advance orders for the Tesla Model 3, more and more of us plan to be driving them. For many of us, the technology is already good enough to meet most if not all of our motoring needs.
Elephant tourism is an activity through which tourists can observe and interact with the stately mammals. A quick online search reveals all sorts of elephant pictures and selfies – patting, washing, riding, and the like. But this popularity comes at a great cost to elephants.
It is always good to learn about more reasons to eat chocolate and Italian researchers have provided us with some impressive facts to digest with our delicious treats.
Carbon dioxide is not a very popular substance. As a greenhouse gas, it is the chief culprit in climate change and, as such, the world continues to seek solutions for preventing its release in the environment.
Sea pickles are translucent, tubular creatures that are usually found in tropical ocean waters. Also known as pyrosomes, they are actually made up of many small multicellular organisms that are linked together in a tunic to form a tubelike colony that is closed on one end.
On Monday, August 21, there will be a total solar eclipse visible in a band across the entire contiguous United States. The last time that happened was in June of 1918. In fact, the last time a total solar eclipse was visible anywhere at all in the continental U.S. was in 1979. So, this is a big deal for American eclipse watchers and millions of us will be heading for some part of the 65-mile-wide band of totality that wends its way from Oregon to South Carolina.
