Imagine you had a robotic dog, and you wanted to try to program it to just do something basic, like walking.

Here, in this article, I will try to give you an idea of how a genetic algorithm works and we will implement the genetic algorithm for function optimization. So, let’s start.

The study was carried out by Professor Li Lanjuan and colleagues from Zhejiang University in Hangzhou, China and published in a non-peer reviewed paper released on website medRxiv.org on Sunday.

Li’s team analyzed the strains from 11 randomly chosen coronavirus patients from Hangzhou, where there have been 1,264 reported cases, and then tested how efficiently they could infect and kill cells.

More than 30 different mutations were detected, of which 19 were previously undiscovered.

Wingcopter and UPS Flight Forward (UPSFF) are collaborating to develop package delivery drones.

The companies will work toward earning regulatory certification for a Wingcopter unmanned aircraft to make commercial delivery flights in the United States, according to a news release. This partnership represents “a critical step toward building a diverse fleet of drones with varying capabilities to meet even more potential customer needs.”

The Wingcopter drone is capable of vertical takeoff and landing in tight spaces and transitioning to high-speed horizontal flight. Its patented tilt-rotor mechanism enables a seamless transition between the two drone modes—multicopter for hovering and fixed-wing for low-noise forward flight. The aerodynamic drone provides stability even in harsh weather conditions.

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.

Circa 2011

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.
