Stanford scientists have invented a flexible, high-performance aluminum battery that charges in about 1 minute.
A new battery developed at Stanford may well revolutionize personal technology. It charges in a minute, lasts thousands of cycles and is much safer than current commercial models. Right now it lacks capacity, but its creators say it's a work in progress.

"We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames," said Hongjie Dai, a chemistry professor at Stanford.

Larger, more destructive earthquakes possible given new link between two California faults

The red line indicates the newly discovered link between the southern end of the Hayward Fault and the Calaveras Fault, once thought to be independent systems.
Two California fault lines — the Calaveras Fault and the Hayward Fault — are actually connected, new research shows, meaning an earthquake resulting from the pair could be much more destructive than originally thought, with a potential for a magnitude 7 quake or greater.

Seismologists from the University of California Berkeley used two decades of satellite data to look at "ground deformation" and "fault creep," a news release explained. Creep describes the constant, slow movement of a fault line as opposed to a fault line that's still between quakes, like San Andreas, according to the U.S. Geological Survey. "The Hayward Fault is actively moving, year-by-year," the USGS noted.

However, as Estelle Chaussard, lead researcher from UC Berkeley, explained to weather.com, though the ground is continuously moving, this movement is not producing any earthquakes. Until, that is, there's a rupture.

Comment: The potential for California to have its predicted 'big one' just got a little a bigger!

Single supernova caused nearly 2000-year-old explosion

A study of 3C 397, a supernova remnant shown here in X-rays from NASA's Chandra X-ray Observatory (purple) and Suzaku (blue), indicates the blast arose from a single white dwarf that accumulated matter from a normal companion star.
New analysis of data from the Japanese Suzaku X-ray satellite has revealed that the well-known supernova remnant named 3C 397 was the result of an explosion involving just one star, not the merging of a pair of white dwarfs, NASA officials revealed on Thursday.

Hiroya Yamaguchi, an astrophysicist at NASA's Goddard Space Flight Center in Maryland, and his colleagues from the US and Japan reviewed observations conducted over five years ago.

"Mounting evidence indicates both of these mechanisms produce what we call type Ia supernovae," Yamaguchi, lead author of a paper published last month in The Astrophysical Journal, said in a statement. "To understand how these stars explode, we need to study the debris in detail with sensitive instruments like those on Suzaku."

Medical ethicist outs scientific community for widespread 'plagiarism, fraud, and predatory publishing'

The scientific community is facing a 'pollution problem' in academic publishing, one that poses a serious threat to the "trustworthiness, utility, and value of science and medicine," according to one of the country's leading medical ethicists.

Arthur L. Caplan, PhD, director of the Division of Medical Ethics in the Department of Population Health at NYU Langone Medical Center, shares these and other observations in a commentary publishing April 3 in the journal Mayo Clinic Proceedings.

"The pollution of science and medicine by plagiarism, fraud, and predatory publishing is corroding the reliability of research," writes Dr. Caplan. "Yet neither the leadership nor those who rely on the truth of science and medicine are sounding the alarm loudly or moving to fix the problem with appropriate energy."

Frenemies? Russia and US agree to joint space projects: New space station and mission to Mars

In a landmark decision, Russian space agency Roscosmos and its US counterpart NASA have agreed to build a new space station after the current International Space Station (ISS) expires. The operation of the ISS was prolonged until 2024.

"We have agreed that Roscosmos and NASA will be working together on the program of a future space station," Roscosmos chief Igor Komarov said during a news conference on Saturday.

The talks were held at Baikonur cosmodrome in Kazakhstan.

The two agencies will be unifying their standards and systems of manned space programs, according to Komarov. "This is very important to future missions and stations."

The ISS life cycle was to expire in 2020. "Under the ISS program the door will be open to other participants," Komarov told reporters.

The next goal for the two agencies is a joint mission to Mars, NASA chief Charles Bolden told journalists.

Roscosmos and NASA are working with each other and other partners on a global roadmap of space exploration, Bolden said. "Our area of cooperation will be Mars. We are discussing how best to use the resources, the finance, we are setting time frames and distributing efforts in order to avoid duplication."

Comment: If NASA "doesn't want" the government to finance low-orbit missions, they - and the government - must have reached an agreement with private companies, notably Virgin Galactic and SpaceX. Governments now seem to be more interested in controlling the lucrative travel destinations: space stations, the Moon and Mars.

Cheap mass transportation - like airlines today - will be left to private companies, since that area isn't so profitable. It appears that governments will have their hands full with mining, extracting resources from the Moon and Mars.

Russian scientists invent bio-cement that will regenerate human bone tissue

Doctors are set to scan damaged bones and 3D-print the missing parts, which will later transform into the recipient's own tissue.

The scientists of the Russian National Research Nuclear University developed a technique to convert animal bones into material that can substitute the damaged parts of human bones, the institution's press service said in a statement.

The new substance is based on biological hydroxyapatite - a white powder that resembles cement when mixed with a biological polymer. It is soft and flexible like plasticine when kneaded but hardens after being placed on the damaged bone.

With time, the organism dissolves this "cement" replacing it with its own bone tissue. As the substance is derived from animal bones, it preserves biological activity, which is an essential advantage and a significant ground for successful regeneration.

Third 'Blood Moon' rises: Total lunar eclipse over the Western U.S.

The moon will pass through the Earth's shadow and turn blood-red in the early hours of the morning on Saturday, in a brief total eclipse best visible from the western part of the US.

It will be the third in a series of four total lunar eclipses, or a "tetrad," that began in mid-April last year. The second occurred in October 2014, and the last will be on September 28 this year. Tetrads are very rare: only seven more are expected by the year 2100.

Saturday's eclipse will also be the shortest in a century, with the moon spending just four minutes and 43 seconds completely in Earth's shadow. However, the time it will take for the moon to become completely occluded will be abnormally long, a whole 102 minutes, writes Space.com. This is because the moon will have just reached apogee, its farthest point from the Earth.

Curiosity drives infant learning, Hopkins research shows


Want to make your baby smarter?

New research by the Johns Hopkins University has found that it may be as simple as throwing some surprises his or her way.

All babies are born with some natural smarts, but youngsters learn more about the world when this innate intelligence is challenged, cognitive psychologists Aimee E. Stahl and Lisa Feigenson discovered in a study that will be published Friday in the journal Science.

Electric cars are not so 'green' after all

© tva.com
Driving an electric car might not be as good for the environment as once thought, according to a report.

A segment on Canada's CBC Radio show "The Current" takes a closer look at the use of electric cars and their actual impact on the earth.

Citing programs that offer incentives to anyone who wants to ditch a gas-powered car for an electric one in Canada, the report says that if everyone switched to the "greener" electric cars, the overall emissions might not be any less than what they are now.

The disconnect lies where the power that fuels electric cars comes from. Electric charging stations are not always green themselves, according to the report, depending on which part of Canada they're in.

Get ready to feast your eyes on an extra special and rare total lunar eclipse Saturday morning that has some Christians worried this Easter weekend.

For the third time in less than a year, the moon will dip into Earth's shadow, turning its bright white globe a deep coppery red in a matter of minutes.

The action begins at 3:16 a.m. PST on the morning of April 4 when the edge of the moon first enters the amber core of Earth's shadow.

For the next hour and 45 minutes, Earth's shadow will move across the lunar disk, ultimately covering the entire moon at 4:58 a.m. PST.

The total phase of the lunar eclipse will only last about 5 minutes, making it the shortest lunar eclipse of the century on the morning of Easter Vigil, traditionally observed as the period between Good Friday and Easter Sunday. The eclipse also falls within the first night of Passover, observed by Jews worldwide beginning Friday at sunset.
