It’s called the C/2022 E3 (ZTF) comet.

A comet that last appeared in the night sky during the Ice Age will soon make a reappearance in February 2023, according to a NASA statement published last week. Called the C/2022 E3 (ZTF) comet, it orbits the sun every 50,000 years. It will now pass within 26 million miles of Earth on February 1st, 2023.

It could also be visible to the naked eye in mid-to-late January. The comet can be seen using binoculars and low-level telescopes when the skies are clear.

Senior corporate officers across the nation are wringing their hands. The 2023 economic climate is uncertain, but one thing is for sure—more layoffs are coming. In November 2022 alone, more than 80,000 layoffs were announced from tech giants like Meta, Amazon, and Twitter, as well as conventional companies like PepsiCo, Goldman Sachs, and Ford.

Downsizing is one of the most difficult things that leaders ever have to accomplish.


AI can offer objective performance evaluation to help managers decide who stays and who goes. AI software startups like GoFusion Perfacto and Entomo use data from employee productivity, attendance record, and other KPIs to help separate the star players from the rest on the basis of objective performance metrics.

This approach provides department heads a justification for their downsizing decisions, freeing both leaders and teams of the worst ills of purely subjective decision-making.

A widely believed theory about the origins of Native Americans has been dealt a huge blow by a new genetic analysis of ancient teeth, implying the ancient inhabitants of what is now America were not who we thought they were.

The theory, largely based on archaeological evidence found at Native American sites, claims that the First Peoples came to the continent from Japan around 15,000 years ago. Stone tools and other stone artifacts used by Native Americans show similarities to those of the Jōmon people, a diverse hunter-gatherer people who lived in ancient Japan from around 14,000–300 BCE.

Based on this and analysis of their migration across the continent, it’s been suggested that Native Americans made their way across the northern rim of the Pacific Ocean, across the Bering Land Bridge – dry land that connected Siberia and Alaska during the last ice age – until they reached the northwest coast of North America.

Claiming 3rd place, we look at how a zero-electricity cooling system could meet the world’s growing AC needs.

The fact that as the Earth warms, the technology needed by humans to stay cool will only make the environment hotter is one of the great ironies of climate change.

Here’s where a novel device unveiled by MIT researchers in October comes in.

In theory, it could mitigate the effects of global warming; but experts are wary.

Make Sunsets, a California-based startup, released weather balloons that carried sulfur particles into the stratosphere which possibly burst there, releasing the chemical, MIT Technology Review.

Recently, a start-up company called Make Sunsets has begun releasing chemicals into the stratosphere as a form of geoengineering that is intended to help climate change. However, many are very hesitant about the startup and the result of what they are doing.

For perspective, geoengineering is when chemical particles are released into the stratosphere to manipulate the weather or climate. The theory is that when sulfur is released into the atmosphere that it mimics a natural process that occurs after volcanoes and that by doing this intentionally, we could ease global warming.

While it isn’t difficult to do this, it is very controversial. The reason for this is that it could potentially have dangerous side effects. Additionally, because some regions could endure worse side effects, it could cause issues across international lines.

The Royal Meteorological Society, which runs the Weather Photographer of the Year competition, has posed an intriguing question: Can artificial intelligence (AI) win a photography competition?

To answer this, the Society drew up a Turing test in which the viewer is invited to guess which is an AI image and which is an actual award-winning photo.

The Turing test, created by Alan Turing in 1950, is a test of a machine’s ability to exhibit intelligent behavior indistinguishable from a human.

While significant parts of the globe are already facing significant freshwater scarcity, the need for more freshwater is projected to increase in order to sustain the increasing global population and economic growth and adapt to climate change.

An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped. Now, researchers at the University of Illinois Urbana-Champaign (UIUC) have proposed a new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.

The study evaluated 14 water-stressed locations across the globe for the feasibility of a hypothetical structure capable of capturing water vapor from above the ocean and condensing it into fresh water – and doing so in a manner that will remain feasible in the face of continued climate change.
