Total emissions from EVs undercut ICE cars in 95% of the world


A new study claims that EVs are better for the environment than gasoline-powered vehicles in 95 percent of the world

 Comparing the eco-credentials of electric cars and their gasoline-powered counterparts isn’t as simple as counting the carbon emissions coming (or not) from the tailpipe. New research is claiming to have settled the debate once and for all by taking all factors into account, including the production of, and electricity generation for, EVs and found that they are better for the climate in 95 percent of the world.

While there is no debate that EVs pollute less once they are actually on the road, some argue that the CO2 generated during the manufacturing of EVs and in the generation of the electricity to charge them actually outweighs that produced by cars with internal combustion engines (ICEs). The thinking is that while renewables can play a part of the energy mix, EV owners still need to rely heavily on coal- and gas-fired power plants to keep their cars charged and running.

The new research was carried out by scientists at the University of Exeter, University of Cambridge and University of Nijmegen in the Netherlands, and found that while there are exceptions, electric vehicles are generally better for the climate in the vast majority of places.

NYSE operator’s crypto project Bakkt brings in $182M

File: Crypto Losses Near $700 Billion In Worst Week Since Bubble Burst

The Intercontinental Exchange’s (ICE) cryptocurrency project Bakkt celebrated New Year’s Eve with the announcement of a $182.5 million equity round from a slew of notable institutional investors. ICE, the operator of several global exchanges, including the New York Stock Exchange, established Bakkt to build a trading platform that enables consumers and institutions to buy, sell, store and spend digital assets.

Bitcoin sees Wall Street warm to trading virtual currency


SAN FRANCISCO — Some of the biggest names on Wall Street are warming up to Bitcoin, a virtual currency that for nearly a decade has been consigned to the unregulated fringes of the financial world.

The parent company of the New York Stock Exchange has been working on an online trading platform that would allow large investors to buy and hold Bitcoin, according to emails and documents viewed by The New York Times and four people briefed on the effort who asked to remain anonymous because the plans were still confidential.

NASA discovers there may be flowing water on Mars

Dark seasonal streaks on crater walls could be flows of salty water.

We have known for a while now that ice exists on Mars.  We have seen a lot of suggestions that liquid water may have once existed on the surface in huge rivers and oceans. But  NASA has announced for the first time, they may have actually spotted some flowing, liquid water.

Road Salt is Affecting Aquatic Life And Drinking Water Across North America

Mountains of salt are spread on snowy roads in North America every winter, and environmentalists have been complaining about it for years. But studies are piling up that indicate that the cost may be too high.

Martin Mittelstaedt reports in the Globe and Mail about a new study of Frenchman’s Bay, a lagoon off Lake Ontario by University of Toronto Geologists. The conclusion:

“Our findings are pretty dramatic, and the effects are felt year-round,” said Nick Eyles, a geology professor at the university and the lead researcher on the project. “We now know that 3,600 tonnes of road salt end up in that small lagoon every winter from direct runoff in creeks and effectively poison it for the rest of the year.”

The brain cooling helmet.

An extraordinary new ‘brain-cooling’ motorcycle helmet could save thousands of lives each year.

Called the ThermaHelm, the incredible piece of equipment comes with an inbuilt device that acts like an instant ice pack after a sudden impact.

By cooling the brain it is thought the carbon fibre helmet can reduce the risk of long-term brain damage and save lives.


Aluminum-Ice Could Power Future Space Travel


Scientists from Purdue University have prepared a new solid propellant with explosive results. The fuel, a combination of nanoaluminum and ice, is a new kind of environmentally friendly solid rocket fuel that could someday be used in missions to outer space. With the motive to minimize fuel consumption onboard, the fuel has been successfully field-tested in a nine-foot rocket which scaled an amazing height of 1300 feet at 200mph using seven inches of nanoaluminum and ice.

Glowing Trail Of Astronaut Urine Spotted In The Night Sky Over North America


The photo actually shows a trail of urine and waste water streaming out of the shuttle Discovery.

The beautiful trail in the sky looked like a mysterious celestial event. In reality, it was urine.  Some skygazers were treated to the unexpected view of a bright sparkling glow Wednesday night, created when astronauts aboard the space shuttle Discovery dumped the waste out into space.

Why Water Expands When It Cools


Water droplet

Most of us, when we take our first science classes, learn that when things cool down, they shrink. (When they heat up, we learn, they usually expand.) However, water seems to be the exception to the rule. Instead of shrinking as it cools, this common liquid actually expands. In order to explain this phenomenon, some scientists have adopted the “mixture” model, which purports that low-density, ice-like components dominate due to cooling. Masakazu Matsumoto, at the Nagoya University Research Center for Materials Science in Japan, has a different idea. He describes his findings in Physical Review Letters: “Why Does Water Expand When It Cools?”
