Schaeffler, a major manufacturer of parts for the automotive and aerospace industries, created the Schaeffler Bio-Hybrid—a vehicle small enough to fit in the bike lane, but that has motor assist and is easily parked. The company plans to build 30-40 Bio-Hybrids for user feedback tests to be conducted in a city in southern German in 2017.
Patrick Seidel, innovation manager at Shaeffler, called the Bio-Hybrid a "solution for future urban transport."
At 2 meters (6.5 feet) long, 1.5 meters (5 feet) tall and 80 centimeters (31 inches) wide, the bike combines pedal-power and electric motors to move. It is easily maneuvered, only weighing 80 kilograms (176 pounds), and is emissions-free, The Guardian reported. Seidel said the weight of the bike might be reduced as the model is improved.
"It may be a little over-engineered at the moment, but we want to prove the concept," Seidel told The Guardian.

The Bio-Hybrid's two batteries are located under the seat, easily accessible and light weight enough to be carried inside for charging. Three to 4 hours are required for full charge, but those batteries then power the bike for a range of 50 to 100 kilometers (31 to 62 miles).
Electric-assisted rides are available up to 15 mph, according to Schaeffler. The Guardian's Damian Carrington describes how it feels to drive the Bio-Hybrid:
You just start pedalling. The battery-powered assist kicks in automatically and off you go at a pleasant clip. Pedal faster and the automatic and continuous gears slide upwards to get you up to 15mph, when the assist ends. The racing-style steering wheel (handlebars?) turns the Bio-Hybrid smoothly and the hand lever-operated disc brakes bring you to a smart stop.
Drivers can vary the level of assist they receive while driving the Bio-Hybrid. A setting of zero gives the biker complete control over the speed of the vehicle, if desired, or they can set the assist at maximum for an easy, laid-back ride. There is also a reverse setting, Carrington said, to help with parking and turning.
Electric assist isn't the only customizable portion of the Bio-Hybrid, the seat and steering wheel, The Guardian said, are adjustable as well.
The bike's roof can be removed and stored behind the seat to create a convertible feel and look. Schaeffler's Bio-Hybrid also comes with a coat hook behind the seat and a luggage rack on the back.

There are a few problems that might have to be fixed, depending on local laws, if the Bio-Hybrid enters the market, such as the lights and mirrors. Carrington wrote:
The integrated lights at the front and back give the Bio-Hybrid a groovy look, but night riders would need to attach more lumens to be safely seen. There are also integrated orange indicators lights, though these would mean the vehicle becomes a car in German law.
"New concepts do not always fit into the legal environment of the moment," Seidel said.
Carrington said the visibility over the driver's shoulders is fine.
Seidel expects the Schaeffler Bio-Hybrid to be pitched with a cost between 2,500 euros (almost $2,800) or even above 7,000 euros ($7,800), which is equivalent to the price of low-end electrical cars.

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
