Wellington International Airport officials believe it may be the longest distance flown in an electric plane across any body of water.
“It’s a very exciting day for the airport. A world-record-setting day,” said spokesperson Jenna Raeburn.

A historian traces the Tesla founder’s passion for space exploration and other futuristic pursuits to dystopian novels and a grandfather’s eccentric convictions.
Conception is starting with blood cells from female donors and trying to transform these into the first “proof-of-concept human egg” made in the lab. The company hasn’t done it yet—nor has anyone else. There are still scientific puzzles to overcome, but Krisiloff sent out an email to supporters earlier this year saying his startup might be “the first in the world to accomplish this goal in the not-too-distant future.” It says that artificial eggs “could become one of the most important technologies ever created.”
That’s no exaggeration. If scientists can generate supplies of eggs, it would break the rules of reproduction as we know them. Women without ovaries—for example, because of cancer or surgery—might be able to have biologically related children. What’s more, lab-made eggs would cancel the age limits on female fertility, allowing women to have related babies at 50 60, or even beyond.
Yay 😃
CERN’s gargantuan particle collider could change everything by discovering a new force of nature.
This rolling sheet of solar panels may not look like much, but it could help spark a solar power revolution in the railroad industry.
The creators of the solar-powered locomotive of the future were aiming to set a Guinness record for speed last weekend, and that is more than just your ordinary attention-getting stunt. Demonstrating the functionality of PV panels on rail cars could help set the stage for solar power to knock diesel fuel out of the railroad business. No word yet on the official results, but solar is beginning to wiggle its way into a field dominated by fossil fuel.

A team of researchers from the University of Florida, led by Dr. Philip Feng, in collaboration with Prof. Steven Shaw in Florida Institute of Technology, has now demonstrated extremely high-efficient mechanical signal amplification in nanoscale mechanical resonators operating at radio frequency. The devices employed in this research might be the tiniest mechanical resonators exhibiting amplification, and the gain achieved is the highest known for all mechanical devices reported to date.
The displacement amplification is realized based on “parametric pumping or parametric amplification” of mechanical motion. Parametric amplification can be mainly achieved when a parameter of system is modulated by twice multiples of the frequency. A simple example of parametric amplification is a child playing a swing. The child can periodically stand and squat twice in a single period of the swing to increase or “amplify” the swing amplitude without anyone helping to push.
The researchers have realized the parametric amplification in the tiny nanoscale devices. The nanoscale drumhead mechanical parametric amplifiers demonstrated in this research consist of an atomically thin two-dimensional semiconducting molybdenum disulfide (MoS2) membrane where the thickness of the drumheads is 0.7, 2.8, 7.7 nanometer with 1.8 micrometer in diameter and 0.0018–0.020 m3 in volume. The nanodrums are fabricated by transferring nanosheet exfoliated from bulk crystal over microcavities to make suspended atomically thin nanodrums.
