· A skyscraper being constructed in Shenzhen, China will be able to produce 270 tons of food through hydroponics. In the 650-foot tower, 100,000 square feet (10,000 sq. meter) of the glass exterior is dedicated to producing food—590,000 pounds of it per year. The windows of the building curve outward and can capture sunlight for the plants of the building and help maintain a comfortable temperature inside. To grow the food an AI will facilitate hydroponic farming which feeds the plants through nutrient-rich water vapors instead of soil. The massive tower will also in including around a million square feet of office space, a supermarket, gardens, and a food court. The building concept was created to be the headquarters of Wumart, a new supermarket chain in the region, to provide an example for sustainable farming in urban areas and a comfortable place for leisure.
A capsule containing moon rocks (shown) collected by China’s Chang’e-5 mission landed back on Earth in December 2020.
· China’s lunar rock samples show lava flowed on the moon 2 billion years ago. Lava oozed across the moon’s surface just 2 billion years ago, bits of lunar rocks retrieved by China’s Chang’e-5 mission reveal. A chemical analysis of the volcanic rocks confirms that the moon remained volcanically active far longer than its size would suggest possible, researchers report online October 7 in Science. This was considered an anomaly since scientists thought that the moon started cooling off around 3 billion years ago, eventually becoming the quiet, inactive neighbor it is today. Tests were done to determine if the cause could have been radioactive elements, but the samples did not indicate that this was the case. Some theories suggest that an asteroid may have hit the moon or that Earth’s gravitational force could have liquified the interior of the planetary body.
Image of neural MRI fingerprint
· Recently, Yale neuroscientists found that our brains have a “fingerprint”. Through MRI imaging of neural connections, they were able to find 95% matching neural patterns through two tests, essentially identifying a person by their brain waves. Other tests were done to see how long these patterns last and the brain fingerprints were found to last about 1 minute and 40 seconds. The neuroscientists also found that the sensory parts of the brain are more likely to show the brain fingerprints of people. This new information will also potentially be able to help doctors identify Alzheimer’s disease in patients since it seems to erode the neural fingerprint over time.
