In Colombia, the hippos originally imported by Pablo Escobar have become an ecological menace. Initially introduced for his private zoo, their population has surged to over eighty, wreaking havoc on local waterways. Their excrement disrupts the delicate balance of river ecology, depleting oxygen levels and triggering harmful algal blooms. Addressing this invasive species poses significant environmental hurdles that require urgent attention.

Green roofs offer a solution to urban heat by absorbing sunlight and releasing water. Vegetation shades surfaces and evapotranspiration naturally cools surrounding areas. These living roofs also manage rainwater and provide habitats for urban wildlife. Extensive and intensive systems cater to different building needs and budgets. Cities worldwide are adopting green roofs to combat rising temperatures and improve environments.

A team of scientists has pioneered an advanced system that converts carbon dioxide directly from factory emissions. This groundbreaking process sidesteps expensive gas separation and purification techniques. By utilizing specially formulated organic electrolytes, the system successfully facilitates the conversion of CO2 into carbon monoxide while minimizing unwanted reactions. This innovation presents a cost-effective solution for curbing carbon emissions from industries.

Unexpectedly, a four-ton SpaceX Falcon 9 rocket stage has collided with the Moon, exhibiting the increasing issue of space debris. After spending over a year in orbit, the remnants triggered observable spectral lines indicative of sodium and lithium gases upon impact. NASA, alongside South Korea, intends to photograph the resulting crater to understand the event better. This incident underscores the urgency of addressing space junk management and its proper disposal.

Aakash Manaswi has pioneered a groundbreaking technique to tackle the Varroa mite crisis threatening honey bee populations. His research indicates that carbon dioxide treatment rivals traditional pesticides in efficacy. This method stands out due to its cost-effectiveness and safety for both bees and consumers, providing beekeepers with a scalable, residue-free solution that supports honey bee conservation and enhances global food security.
