Bosch unveils smart electric stroller with smartphone connectivity

Bosch unveils smart electric stroller with smartphone connectivity Multinational tech and service supplier Bosch has unveiled the e-Stroller, a smart stroller with intelligent sensors and smartphone connectivity that can help parents push the stroller uphill. As more modes of transportation get intelligent tech to improve driver and passenger safety and comfort, it was only a matter of time before smart strollers began to saturate the market. On Monday Bosch announced its own rendition of the smart stroller equipped with tech that understands the terrain it's rolling on, the steepness of its path, and its own speed and acceleration.

The average shock from an electric eel lasts about two-thousandths of a second. The pain isn’t searing “It’s quite literally shocking , when you discover new diversity in such an eye-catching fish first described Electric eels possess a specialized nervous system that synchronizes the activity of

It's an update to the electric eel family tree that's been over 250 years in the making.

The electric eel was first described by the famed Swedish scientist Carl Linnaeus in 1766.

But after years of hanging out on its own as the only species in the genus Electrophorus, researchers have now discovered that the electric eel, Electrophorus electricus, is in fact not one species but three.

The only species of electric eel previously known to science was Electrophorus electricus, which Swedish naturalist Carl Linnaeus described in 1766. During field measurements using a voltmeter, he said the research team recorded a discharge of 860 volts, the highest found in any animal , for a

Genetic data has revealed several distinct electric eel species living throughout South America, including the most shocking eel (and animal ) discovered yet. Scientists have assumed that the electric eel comprised a single species , ever since taxonomist Carl Linnaeus first described the

It's far above the 650V previously recorded for the electric eel, making E.voltai the most powerful electricity-generating animal in the world, the authors report in Nature Communications today.

But before you get worried about getting too close, its discharge is high voltage but low amperage they said, so it wouldn't necessarily be dangerous to humans. (If we think of electricity as water flowing through a hose, the amperage (current) is how fast the water is flowing, and the voltage is the water pressure that pushes the water through the hose.)

The findings are the result of an ongoing study aiming to describe most of the species of South America's electric fishes and place them in the fish tree of life, said zoologist and lead author of the paper C. David de Santana of the Smithsonian's National Museum of Natural History.

South American rivers are home to at least three different species of electric eels , including a newly identified species capable of generating a greater electrical discharge than any other known animal , according to a new analysis of 107 fish collected in Brazil, French Guiana, Guyana and Suriname in

The only species of electric eel previously known to science was Electrophorus electricus, which Shocking diversity. According to Santana, who has entered many rivers to collect electric eels for "The discovery of new electric eel species in Amazonia, one of the planet's biodiversity hotspots, is

And that includes one of the continent's most fascinating animals, the electric eel. Fun fact: it's not actually an eel at all, but rather a type of knifefish that grow up to 2.5 metres in length.

"In spite of all the human impact to the Amazon rainforest in the past 50 years we can still discover undescribed giant fishes like two new species of electric eels," Dr de Santana said.

Electric fishes are fish that can generate electricity, or are electrogenic, as opposed to fish which are electroreceptive, meaning they can detect electric fields —although some species can be both.

Other examples of electric fish include electric rays and electric catfish.

Over a period of six years, Dr de Santana and his colleagues collected 107 electric eel specimens from across the Amazon basin and closely examined them.

While the animals looked very similar, the scientists discovered genetic differences in their DNA that showed they were in fact three different species.

Fisherman gets shock as he reels in 'dinosaur-like' fish with huge eyes

Oscar Lundahl is believed to have nearly jumped out of his boat when he saw on the end of his line the strange-looking species with large, bulbous eyes. It turned out the creature was a ratfish, which lives in deep water and is distantly related to sharks. It is harmless to humans and gets its name from its long, thin tail that some scientists in the past believed resembled a rat's. The ratfish's large eyes help in the dark as they reflect light like those of cats.

Two new species of electric eel have been discovered , which not only triples the number of known electric eels , but one of them has the highest Meet Electrophorus voltai, one of the two new species of electric eel confirmed, and owner of the most powerful electric shock in the animal kingdom.

A new species of electric eel with the most powerful shock of any animal ever discovered has been found in the Amazon. The electric eel —which is not a true eel , but rather a South American knifefish—can generate pulses of electricity it pushes through water to shock prey and defend itself.

They've also determined that the three species live in different parts of the Amazon.

While E. electricus is found in the highlands of the Guiana Shield, and E. voltai call the highlands of the Brazilian Shield home, the third species Electrophorus varii prefers the murky lowland waters.

For Dr de Santana, the finding is the only the beginning of what we might be able to discover in the Amazon's depths.

"The discovery of hidden species diversity of such an eye-catching and long-known organism as electric eels, indicates that an enormous amount of species are waiting to be discovered in the Amazon rainforest," he said.

"Many of which may harbour cures for diseases or inspire technological innovations, reinforcing the critical need to protect Earth's hotspots of biodiversity."

How common are electric animals?

The study suggests that perhaps there are many other animals out there capable of generating electricity that we haven't studied yet, commented Darryl Whitehead of the University of Queensland, who studies electroreception and electric fishes.

A newly discovered species of electric eel produces an 860 volt shock , the highest charge of any known animal in the world. The creature is one of two extra species of the fish identified by scientists, who examined 107 specimens from across the Amazon rainforest.

The electric eel (Electrophorus electricus, other species proposed) is a South American electric fish. Until 2019, it was classified as the only species in its genus.

Dr Whitehead said we're unlikely to find land-based animals that can generate electricity because air doesn't conduct electricity as well as water, so there's no real reason for them to do so.

Electric fish use electric organs to generate electricity, which are made of modified muscle cells called electrocytes.

"The ability has been developed at least six times in the fish environment, and these fishes are in no way related to each other," Dr Whitehead said.

It's an example of convergent evolution that even got Charles Darwin's attention, and recent research has looked at whether there could be common genetic factors at play.

Electric eels have three electric organs that can produce strong electrical discharges as well as weak discharges:

  • The Main organ produces more of the strong electric organ discharge
  • Sach's organ generates weak electric discharges
  • Hunter's organ at the front of the animal works as a Main organ, and at the back of the animal as a Sach's organ

"The three organs are arranged as batteries in series inside a flashlight, and fire simultaneously by entire-body muscle contractions caused by the direct stimulation of spinal motor neurons," he said.

“The discovery of hidden species diversity on such an eye-catching ( more than 2.5 meters/8 feet long) and long-known (described 250 years ago) organism indicates that an enormous amount of species are waiting to be discovered in the Amazon rainforest,” The researchers examined 107 electric eels

From fascination to inspiration

While people have been fascinated by electric eels and other electric fishes for years, we've also been inspired by them.

The ancient Egyptians, Greeks and Romans all used electric fish in early medicine, to numb people or treat conditions like gout or headache.

Newly discovered species of electric eel can produce most powerful electric shock of any animal© ABC News Electric eels inspired the design of Italian physicist Alessandro Volta's first electric battery, said Dr de Santana, and an enzyme extracted from their electric organs has been used as a target for drugs to treat Alzheimer's disease.

More recently, he said, electrical eels have promoted the advance of hydrogel batteries (made of a substance similar to gelatin) that could be used to power medical implants.

Closer to home, scientists have been inspired by an electric ray that lives in Sydney Harbour called the coffin ray (Hypnos monopterygius), said biomedical engineer Alistair McEwan of the University of Sydney.

"They use electrical sensing like a shark to see around them, but not just passively by listening into the electricity, but also by sending out their own electric field to map the world around them," Professor McEwan said.

The researchers have looked at how to emulate this system to sense changes in the heart, for example to monitor internal cardiac surgery, and in the brain.

"We used that in the brain to find different parts of the brain, and maybe a part of the brain that's not working properly, like what would happen in a stroke or epilepsy or a child with cerebral palsy," he said.

Now, Professor McEwan and his colleagues are looking at how they might be able to use the electroreception abilities of the platypus and the echidna.

"We thought the electroreception would only work well with water. It's amazing the platypus works well in fresh water without conductive salt, but even more amazing that the echidna can electrically sense in the dry desert," he said.

"We can use these to inspire new types of communication systems and perhaps new sensing systems for people with disabilities or possibly for anyone who wanted an augmented sense."
