Peak laser intensity demonstrations have occurred on specific Nd:glass-based lasers: * the Vulcan PW in the UK at 1 × 10^21 W/cm2 (2004); * the Ti:sapphirebased HERCULES laser at the University of Michigan, USA at 1 × 10^22 W/cm2 (2004) * J-KAREN-P in Japan at 1 × 10^22 W/cm2 (2018) * record intensity of 5.5 …
Canadian researchers at the Advanced Laser Light Source (ALLS) facility at INRS, generated 300 terawatt laser pulses (3 joules for a 10-femtosecond pulse). They plan to repeat the experiment with an energy of 3 petawatts (3000 trillion Watts – 13 joules over 5 femtoseconds). ALLS/LSF (Advanced Laser Light Source/ Laboratoire de Sources Femtosecondes) is a …
Tiny, 3D printed cubes of plastic, with intricate fractal voids built into them, have proven to be effective at dissipating shockwaves, potentially leading to new types of lightweight armor and structural materials effective against explosions and impacts. The researchers tested their fractal structures by firing an impactor into them at approximately 670 miles per hour. …
Russia’s military is so meaningless to the US that the annual report on the capabilities of Russia’s armed forces is two pages long and a one-paragraph disclaimer. Oil and gas production makes up about 39% of Russia’s economy. Oil prices in 2020 are about half the level in 2018. Coronavirus is also impacting Russia’s economy …
Higher levels of humanin, a peptide encoded in the small genome of the mitochondria, in the body is linked to longer lifespans and better health. Aging Journal – The mitochondrial derived peptide humanin is a regulator of lifespan and healthspan The scientists observed that species which are already predisposed to long life, including the naked …
Tesla is trading at a valuation of over $250 billion. If Tesla has no factory shutdowns they will build another 55,000 cars in future quarters and they are expanding capacity. This could be 160,000 cars in the third quarter and 200,000 cars in the fourth quarter. Tesla has auto margin of 25-30% and quarterly fixed …
Team members of the Miniature Radio Frequency (Mini-RF) instrument on NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft found new evidence that the Moon’s subsurface might be richer in metals, like iron and titanium, than researchers thought. Using Mini-RF, the researchers sought to measure an electrical property within lunar soil piled on crater floors in the Moon’s …
NASA’s Space Launch System (SLS) Program is concluding its structural qualification test series with one upcoming final test that will push it to failure. Late in 2019, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama tested NASA’s Space Launch System liquid hydrogen test article tank to failure. The tank withstood more than 260% …
Extreme metamaterial ceramic solar sails survive a close pass of our sun to reach speeds of 60-70AU per year which is over 0.1% of light speed. Theis propel low mass spacecraft using a dive to extreme proximity to the sun (just 2-5 solar radii). This velocity is 20 times more than Voyager 1. The technology …
Worldometers estimates the world population is 7.796 billion. This is increasing by 224,400 people every day. This means we are about 900 days from 8 billion people. Worldometers is leveraging UN population estimates. The UN leverages the population counts of countries. In Nigeria, censuses are controversial: The country has even gone as far as annulling …
A meter-class telescope with a coronagraph to block solar light, placed in the strong interference region of the solar gravitational lens (SGL), is capable of imaging an exoplanet at a distance of up to 30 parsecs with a few 10 km-scale resolution on its surface. The picture shows results of a simulation of the effects …
