A sperm’s task may appear straightforward; after all, all it needs to do is swim to an egg and insert genetic material. However, in some cases, a healthy sperm’s inability to swim may result in infertility, which affects around 7 percent of all males.
This condition is called asthenozoospermia, and there is currently no cure. However, one study conducted in 2016 and published in the journal Nano Letters has set the example for what could be possible in the future: A team of researchers from the Institute for Integrative Nanosciences at IFW Dresden in Germany developed tiny motors that can make sperm swim better as they make their way to an egg, essentially acting as a taxi.
These so-called “spermbots” basically consist of a tiny micromotor, which is basically a spiraling piece of metal that wraps around the sperm’s tail. Serving as an “on-board power supply”, the motor navigates the sperm via a magnetic field, helping the sperm swim to the egg with ease. When the sperm makes contact with the egg for fertilization, the motor slips right off, and the magnetic field doesn’t harm any of the cells involved, making it ideal for usage on living tissue, according to the researchers.
A ship in the Pacific Ocean carrying a high-power laser takes aim at a U.S. spy satellite, blinding its sensors and denying the United States critical eyes in the sky.
This is one scenario that military officials and civilian leaders fear could lead to escalation and wider conflict as rival nations like China and Russia step up development and deployments of anti-satellite weapons.
If a satellite came under attack, depending on the circumstances, “the appropriate measures can be taken,” said Lt. Gen. John Shaw, deputy commander of U.S. Space Command.
The space battlefield is not science fiction and anti-satellite weapons are going to be a reality in future armed conflicts, Shaw said at the recent 36th Space Symposium in Colorado Springs.
U.S. Space Command is responsible for military operations in the space domain, which starts at the Kármán line, some 100 kilometers (62 miles) above the Earth’s surface. This puts Space Command in charge of protecting U.S. satellites from attacks and figuring out how to respond if hostile acts do occur.
Military space assets like satellites and ground systems typically have been considered “support” equipment that provide valuable services such as communications, navigation data and early warning of missile launches. But as the Pentagon has grown increasingly dependent on space, satellites are becoming strategic assets and coveted targets for adversaries.
“It is impossible to overstate the importance of space-based systems to national security,” Air Force Secretary Frank Kendall said in a keynote speech at the symposium.
HR 4225 was introduced to the House Committee on the Judiciary on June 29 of this year by Representative Ted Deutsch (D-FL). A few short days later, an identical bill, S.2319, was introduced by Senator Ed Markey (D-MA) in the Senate.
Officially, S.2319 is referred to as the 3D Printed Gun Safety Act of 2021.
They’re ready to take gun control to a whole new level with this.
But you may know it as its mainstream media coined term: The Ghost Gun Ban
According to the US government, the stated intention of S.2319 is “to amend chapter 44 of title 18, United States Code, to prohibit the distribution of 3D printer plans for the printing of firearms, and for other purposes.” After the bill was introduced, 27 Senators throughout the US – all Democrat (with the exception of stated Independent, Bernie Sanders) – jumped on board to sign it.
When Joseph Sobolewski got thirsty last month, he saw a sign in a nearby convenience store that was advertising two 20-ounce Mountain Dew bottles for $3. Sobolewksi only wanted one bottle, so he grabbed it, threw down two $1 bills — thinking he’d left a tip — and walked out of the store. Now he’s facing 7 years in prison over it.
Because Sobolewski didn’t realize that the sale price only applied to the two-bottle deal, instead of leaving a tip like he thought, he was actually short. A single bottle costs $2.29 and with tax applied, he was actually $0.43 short.
Instead of simply realizing the error and chalking it up to a harmless mistake, the store called the police — over 43 cents. According to police, the store clerk followed Sobolewski out of the store and told him that $2.00 was not enough, but when he did the math for a $1.50 soda, it was more than enough, so he drove off.
How it escalated to the next level of police involvement is unclear as the clerk told police that Sobelewski “threw $2 onto the checkout counter.” And, by his math, he actually tipped the clerk.
When police caught up to Sobolewski, instead of simply asking him for two quarters to pay his tab, they arrested him on felony theft charges and locked him in a cage because the store clerk wanted him to be punished. According to Pennsylvania State police spokeswoman Megan Ammerman, troopers “cannot decide to not charge someone for a criminal case, only victims of certain crimes can decline charges. If we are called to an incident involving a crime we follow and enforce the PA Crimes Code.”
After he was arrested and thrown in a cage, to top it off, they set his bail at a $50,000 cash-only bond, meaning he will sit in that cage until his trial in November as he is unable to pay for it.
An apparent training exercise at Fort Meade in Maryland prompted a number of national outlets to report that multiple people had been shot at the facility Thursday morning.
CNN, along with at least one AFP reporter and The Sun, reported on the incident.
The AFP and The Sun have since updated that the incident was an exercise.
The size of a grain of sand, dispersed microfliers could monitor air pollution, airborne disease, and environmental contamination.
Northwestern University engineers have added a new capability to electronic microchips: flight.
About the size of a grain of sand, the new flying microchip (or “microflier”) does not have a motor or engine. Instead, it catches flight on the wind — much like a maple tree’s propeller seed — and spins like a helicopter through the air toward the ground.
By studying maple trees and other types of wind-dispersed seeds, the engineers optimized the microflier’s aerodynamics to ensure that it — when dropped at a high elevation — falls at a slow velocity in a controlled manner. This behavior stabilizes its flight, ensures dispersal over a broad area and increases the amount of time it interacts with the air, making it ideal for monitoring air pollution and airborne disease.
As the smallest-ever human-made flying structures, these microfliers also can be packed with ultra-miniaturized technology, including sensors, power sources, antennas for wireless communication and embedded memory to store data.
Project Veritas released a shocking video of a Food and Drug Administration (FDA) official advocating for the government use of drones to “blow dart” COVID-19 vaccines into black people and vaccine resisters.
In a disturbing video by Project Veritas, an effeminate FDA official told an undercover journalist that the government should use drones to “blow darts” of the COVID-19 vaccine into black people and vaccine resisters, signaling his support for a Nazi-style registry for the unvaccinated. “That’s where we’re going,” said the FDA’s Taylor Lee.“Census goes door-to-door if you don’t respond. So, we have the infrastructure to do it [forced COVID vaccinations]. I mean, it’ll cost a ton of money,” Taylor said. “But I think, at that point, I think there needs to be a registry of people who aren’t vaccinated. Although that’s sounding very [much like Nazi] Germany.”
“Nazi Germany…I mean, think about it like the Jewish Star [for unvaccinated Americans],” he said. “So, if you put every anti-vaxxer, like sheep, into like Texas and you closed off Texas from the rest of the world, and you go, ‘Okay, you be you in Texas until we deal with this [pandemic].’”
