Benchmark US crude oil prices traded with negative prices for the first time in history on Monday, sending shockwaves through the global energy sector.

But what are negative prices and what do they mean for the wider industry?

US oil prices traded below zero for the first time ever, meaning producers or traders were essentially paying other market participants to take the oil off their hands.

👽 A slap to health workers.

Opening America. The President keeps teasing it in his daily propaganda, ego-stroke photo op. His sycophantic surrogates repeat the refrain on social media and in press releases. Soulless partisan television hosts pound us relentlessly with it. MAGA cult members protest mask-less and in close quarters for it.

Last March, Chinese researchers announced an ingenious and potentially devastating attack against one of America’s most prized technological assets—a Tesla electric car.

The team, from the security lab of the Chinese tech giant Tencent, demonstrated several ways to fool the AI algorithms on Tesla’s car. By subtly altering the data fed to the car’s sensors, the researchers were able to bamboozle and bewilder the artificial intelligence that runs the vehicle.

National Eye Institute (NEI) researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression. The findings, published online April 21 in Cell Reports, suggest that the epigenome could be targeted as a therapeutic strategy to prevent leading causes of vision loss, such as age-related macular degeneration (AMD). NEI is part of the National Institutes of Health.

“Our study elucidates the molecular changes and biological pathways linked with aging of rod photoreceptors, light-sensing cells of the retina. Future investigations can now move forward to study how we can prevent or delay vision loss in aging and hopefully reduce the risk of associated neurodegeneration” said the study’s lead investigator, Anand Swaroop, Ph.D., senior investigator and chief of the NEI Neurobiology, Neurodegeneration, and Repair Laboratory.

Each organism is born with a genome, a library of genes that control all the body’s cellular and tissue functions. Expression of those genes—when information stored in DNA is converted into instructions for making proteins or other molecules—is modulated and maintained by the organism’s epigenome. The epigenome tags the DNA code to modify gene expression in ways that can be favorable and unfavorable for survival.

The U.S. Air Force is working to produce its next-generation fighter jet, and word has it that the energy around the project is going to be electric. Literally.

It’s called the “F-X” concept (not to be confused with the VFAX/VFX/FX concepts of the 1960s and ’70s) and it’s intended to enter service in 2030.

The ubiquitous particles are helping to map the innards of pyramids and volcanoes, and spot missing nuclear waste.

After ‘reanalyzing’ data from NASA’s Kepler Space Telescope, scientists have discovered an Earth-size planet, named Kepler-1649c, residing in its star system’s habitable zone. Full Story: https://www.space.com/earth-size-exoplanet-habitable-zone-kepler.html

When people say quantum computing is “hot” right now they are most definitely talking metaphorically; today’s leading devices have to operate at close to absolute zero. Now two research groups have demonstrated technology that run s 15 times hotter, which could be a big step towards making the devices affordable and practical.

The reason quantum computers have to be run at such low temperatures is that the quantum states they rely on are incredibly fragile, and the slightest disturbance can cause the information encoded in them to be lost. To prevent this these devices are chilled to near absolute zero, where vibrations and thermal fluctuation are almost non existent.
