It's common to hear that electric vehicles are "zero-emissions vehicles," meaning they emit no greenhouse gases while a user drives them. While technically true, this is far from the whole picture, because what also matters is the lifetime environmental impact of an electric vehicle.

Hector ('the Convector') forming over the Tiwi Islands near Australia
Meteorologists and scientists tend to assign names to natural phenomena that have a significant impact. Hurricanes are one specific example of this naming process. This organization makes it easier to document and communicate about these events. Instead of mentioning the type of storm, time of year, and location, scientists can simply refer to the assigned name and everyone is on the same page. While prominence is a major factor determining whether a storm is given enough attention to receive a name, there are some smaller examples that earn their own title. The Tiwi Islands, that lie just off the coast of the Northern Territory of Australia, are home to such a storm known as Hector. Hector Storm or Hector the Convector are two other widely-used names as well.

Galaxy clusters, the largest structures in the Universe held together by gravity, contain thousands of individual galaxies, dark matter and hot gas.
It came from a supermassive black hole at the centre the Ophiuchus galaxy cluster, about 390 million light-years from Earth, and released five times more energy than the previous record holder, according to a paper to be published in The Astrophysical Journal and currently available on the pre-print server arXiv.
It was so powerful, the authors say, that it punched a cavity in the cluster plasma - the super-hot gas surrounding the black hole.
"We've seen outbursts in the centres of galaxies before but this one is really, really massive - and we don't know why it's so big," says Melanie Johnston-Hollitt, from the Curtin University, Australia, node of the International Centre for Radio Astronomy Research (ICRAR).
"But it happened very slowly - like an explosion in slow motion that took place over hundreds of millions of years."
The study brought together a team from Australia, the US and New Zealand.

The meeting, titled "God and/or Evolution?" was part conversation, part debate. Behe made the case for intelligent design in biology. Swamidass argued for methodological naturalism and modern evolutionary theory while also allowing for the separate de novo creation of Adam and Eve, an idea outlined in his new book.
The format had Behe going first and then Swamidass responding. Then each speaker got a shorter chunk of time for follow-up comments, followed by a Q&A sent via tweets that were selected and read by the moderator.
Behe began by noting that his three books, including his newest one, Darwin Devolves, make two main arguments. The first is that "Darwin's mechanism is grossly inadequate to explain the molecular structure of life." But then he said that due to time constraints he wouldn't focus on that tonight, and that this thesis was the less controversial of the two, since there are today many prominent scientists who question the creative power of neo-Darwinism's joint mechanism of random mutations and natural selection.
Grey whales are far more likely to strand on days when there are more sunspots, researchers from Duke University found.
The finding suggests that the migrating animals may use a magnetic sense to navigate, which is disrupted by solar activity.
Sunspots are linked to solar storms, a sudden release of high-energy particles from the sun that can disrupt magnetic orientation.
The Duke University researchers analysed 186 live strandings of grey whales and the results showed they occurred significantly more on days with high sunspot counts.
In a study, researchers figured out a new way to coax human pluripotent stem cells (hPSCs) into pancreatic beta cells that make insulin. When these insulin-producing cells were transplanted into mice induced to have an acute form of diabetes, their condition was rapidly cured.
"These mice had very severe diabetes with blood sugar readings of more than 500 milligrams per decilitre of blood - levels that could be fatal for a person," explains biomedical engineer Jeffrey R. Millman from Washington University.
"When we gave the mice the insulin-secreting cells, within two weeks their blood glucose levels had returned to normal and stayed that way for many months."
Rus Hoelzel at the University of Durham, UK and his colleagues looked at the mitochondrial DNA from human remains at 4th and 11th century archaeological sites in England, and compared them to samples from the modern population stored on DNA databases such as GenBank. They found there was more variation in the ancient mitochondrial DNA sequences than in modern sequences.
Hoelzel thinks random genetic drift may have lowered genetic diversity naturally. But the large unexpected drop in diversity was more likely to have been caused by population crashes following major outbreaks of the Black Death in England during the 1340s and the 1660s.
"The main factors in support of a role for plague are the timing and the fact that it affected different families [to a differing degree]," says Hoelzel.
Comment: Note that, 600 years ago, they CLOSED BORDERS!
This is something only a handful of countries seem prepared to do with the current Coronavirus epidemic. Russia did so wrt China early on, and it has still only recorded two cases, both of them Chinese nationals, and both now recovered.
But the 'Black Death' of the mid-14th century, and its similar recurrences over the next two centuries, were in a whole other league. The astrobiologists are likely correct: truly civilization-decimating viruses come from outer space...
New Light on the Black Death: The Viral and Cosmic Connection

Spores of the parasite H. salminicola swim under a microscope. Those alien "eyes" are actually stinger cells, one of the few features this organism hasn't evolved away.
If you spent your entire life infecting the dense muscle tissues of fish and underwater worms, like H. salminicola does, you probably wouldn't have much opportunity to turn oxygen into energy, either. However, all other multicellular animals on Earth whose DNA scientists have had a chance to sequence have some respiratory genes. According to a new study published today (Feb. 24) in the journal Proceedings of the National Academy of Sciences, H. salminicola's genome does not.
A microscopic and genomic analysis of the creature revealed that, unlike all other known animals, H. salminicola has no mitochondrial genome — the small but crucial portion of DNA stored in an animal's mitochondria that includes genes responsible for respiration.

Joe Nadeau, principal scientist at the Pacific Northwest Research Institute, is challenging this dogma. Random fertilization should lead to specific ratios of gene combinations in offspring, but Nadeau has found two examples just from his own lab that indicate fertilization can be far from random: Certain pairings of gamete genes are much more likely than others. After ruling out obvious alternative explanations, he could only conclude that fertilization wasn't random at all.
"It's the gamete equivalent of choosing a partner," Nadeau said.
His hypothesis - that the egg could woo sperm with specific genes and vice versa - is part of a growing realization in biology that the egg is not the submissive, docile cell that scientists long thought it was. Instead, researchers now see the egg as an equal and active player in reproduction, adding layers of evolutionary control and selection to one of the most important processes in life.
Comment: If true that the egg 'chooses' or selects for the best genetic package, then the idea that random mutations lead to evolution (which already has a probability so low that it can be said to be impossible) is even less likely to happen.
