this week’s science news was filled with groundbreaking discoveries in the field of astronomy, notably regarding the comet 3I/ATLAS. This interstellar visitor from beyond our solar system has captured the attention of scientists since its initial sighting in late June. Now, after months of research and observation, we are finally gaining a better understanding of its origins and properties.
According too recent findings, it is believed that the comet originated in the far reaches of our galaxy and could perhaps be billions of years older than our own sun. This makes it a valuable relic from the early beginnings of our universe.
In addition to this revelation, astronomers have also observed some unusual characteristics about 3I/ATLAS. one notable observation is that it appears to be spewing water “like a fire hose” before even reaching close proximity to the sun. To further study this phenomenon, researchers have deployed the European Space Agency’s Mars spacecraft for a closer look at its bright coma.
The Latest astronomical Discoveries
Aside from these exciting developments surrounding 3I/ATLAS,there were also othre noteworthy astronomical discoveries made this week:
- The first ever radio telescope imaging of two black holes orbiting each other
- Tentative evidence for controversial dark matter stars
- The James Webb Space Telescope proving Einstein right eight times over with its detection of an octet of stunning gravitational lenses
A Strange Gravity Signal Inside Earth
Along with these discoveries,scientists have also made an intriguing observation about Earth’s own gravitational field. In 2007, a gravity anomaly appeared that was provided that the entire continent of Africa. This anomaly coincided with a geomagnetic jerk, but it wasn’t until recently that researchers discovered this signal hidden within data collected by satellites.
Further research is needed to fully understand this phenomenon, but it is believed to be caused by a previously unknown geological process near Earth’s core. This highlights the importance of continued exploration and study of our planet and its surroundings.
Uncovering the True Discoverers of America
The discovery of America is often attributed to Christopher Columbus, but the truth is much more complex and spans thousands of years. From Native Americans to Vikings and Polynesian seafarers, there were many who discovered and inhabited the Western Hemisphere long before Europeans arrived.
Prehistoric Discoveries
The first humans to discover America were likely prehistoric nomadic groups who crossed over from Asia via a land bridge that connected Siberia to Alaska during the last Ice Age. These early inhabitants spread throughout North and South America, developing unique cultures and civilizations.
Vikings in Newfoundland
In 1000 AD, Viking explorer Leif Erikson landed on the coast of Newfoundland in present-day Canada. This was the first recorded European contact with North America, although it did not lead to permanent settlement or widespread knowledge among Europeans.
Polynesian Seafarers
Evidence suggests that Polynesian seafarers may have also discovered parts of south America around 1200 AD. Oral histories from indigenous peoples in Ecuador tell of a group called “the white men” who arrived by boat from across the sea.
AI Designs New Viruses
In recent years, artificial intelligence (AI) has been used for various tasks such as image recognition and language translation. But now, scientists are using AI for a new purpose: designing new viruses.

researchers at the University of Cambridge have developed a machine learning algorithm that can generate new viruses by analyzing existing ones. This could potentially help scientists better understand how viruses evolve and spread, and aid in the development of new treatments and vaccines.
The algorithm works by analyzing the genetic sequences of viruses and identifying patterns that are associated with certain traits, such as how easily a virus can spread or how deadly it is. It then uses this information to generate new viruses with similar characteristics.
While this technology has potential benefits, there are also concerns about its potential misuse. Some worry that it could be used to create risky viruses for bioterrorism or accidental release.

As scientists continue to make advancements in artificial intelligence (AI), there is growing concern about the potential for AI to be used for malicious purposes, such as creating new viruses. While current biosecurity measures may not be equipped to handle this threat, researchers are working on solutions and regulations to prevent it from becoming a reality.
One recent development in AI is the ability to design wholly new viruses. These viruses, known as bacteriophages, are designed by algorithms that use genetic information from existing viruses. The goal of this research is to create phages that can target and destroy antibiotic-resistant bacteria.
Though, there are concerns about the potential for these AI-designed viruses to be used as bioweapons. While the researchers have taken precautions to ensure their models cannot create pathogens that can infect humans or animals, there are still risks and loopholes that could potentially lead to catastrophic consequences.
This highlights the need for stricter regulations and oversight when it comes to AI research and development. As technology continues to advance at a rapid pace, it is crucial that we consider the potential consequences of our actions and take steps towards responsible innovation.
In addition, current limitations mean that this threat is not immediate. Though, with our adhoc approach towards regulating AI, it could become a reality sooner than we think.

As technology continues to advance,it is indeed crucial that we consider the ethical implications and take steps towards responsible innovation.The first half of 2025 saw a record-breaking number of extreme weather events in the United States, causing widespread damage and destruction. From wildfires to tornadoes, heatwaves to floods, the effects of climate change are becoming increasingly evident.
In this in-depth analysis, we delve into the economic costs of these extreme weather events. By June 2025 alone,they had already caused over $100 billion in damages. And unfortunately, scientists predict that this trend will onyl continue to worsen.
But it’s not just about the financial impact. The toll on human lives and communities is immeasurable. As we face more frequent and severe natural disasters due to climate change, it’s important for us to understand the true cost and take action towards mitigating its effects.
So what can we do? Let’s take a look at some potential solutions:
- Investing in renewable energy sources: By transitioning away from fossil fuels and towards clean energy sources like solar and wind power, we can reduce our carbon footprint and slow down the rate of climate change.
- Implementing enduring practices: From reducing waste to conserving water, small changes in our daily habits can have a big impact on reducing greenhouse gas emissions.
- Supporting policies that address climate change: It’s critically important for governments around the world to prioritize addressing climate change through legislation and regulations.
- Educating ourselves about climate change: The more informed we are about the issue at hand, the better equipped we will be to make positive changes in our own lives as well as advocate for larger-scale action.
As individuals living on this planet together, it is our responsibility to take care of it for future generations. Let’s work towards creating a more sustainable future by taking action against climate change now.
