What are the significant scientific developments that took place in January?

From the discovery that water in plastic bottles contains thousands of nanoplastics that pose a threat to human health, to the discovery of a massive ring-shaped structure in space that "defies theories," and the finding of a new type of antibiotic capable of fighting drug-resistant bacteria, to battery-free sensors that can generate their own energy from magnetic fields, many discoveries and developments made headlines in January.

Every discovery, innovation, and breakthrough in the world of science and technology continues to shape our understanding of the universe and broaden our horizons by revealing the unknown aspects of the cosmos.

The world's oldest fossilized amniote skin, dating back approximately 289 million years, was found in a cave in the US state of Oklahoma.

It was stated that the fossil belongs to a small, lizard-like animal, likely known as "Captorhinus aguti," which predates dinosaurs by millions of years.

Water in plastic bottles contains thousands of nanoplastics dangerous to human health

Researchers from Columbia University in the US have succeeded in identifying particles that can be measured at the scale of one billionth of a meter using a new method, determining that there are approximately 240 thousand nanoplastics in a one-liter plastic bottle of water.

The researchers, who believe that these plastics show rapid effects because they enter the body through drinking water, stated that small plastics could lead to the impairment of microbes in the gut that help digest food.

Furthermore, it is assessed that these plastics could cause health risks such as increased mortality rates and birth defects.

"Theory-defying" massive space discovery

Scientists from the University of Central Lancashire (UCLan) in the UK have discovered a massive ring-shaped structure in space that "challenges" some fundamental assumptions about cosmology.

While cosmologists theoretically calculate the limit of the current size of structures at 1.2 billion light-years, it was determined that this structure, which scientists have named the "Big Ring," has a diameter of 1.3 billion light-years and a circumference of approximately 4 billion light-years.

The researchers are of the opinion that the newly discovered structure contradicts the 1.2 billion light-year theory.

Chatbots responded to "malicious" commands via "reverse engineering"

Researchers at Nanyang Technological University (NTU) in Singapore enabled artificial intelligence chatbots to respond to commands they would normally be unable to answer using a "reverse engineering" method.

The researchers conducted a study on chatbots such as ChatGPT, Google Bard, and Microsoft Bing Chat.

With this method, it was first determined how chatbots detect malicious queries and defend themselves. Then, using this information, chatbots were taught to automatically generate commands that could bypass the defenses of other models.

Antibiotic found that can fight drug-resistant bacteria

Researchers from Harvard University and the Swiss pharmaceutical company Hoffmann-La Roche examined approximately 45 thousand antibiotic molecules to find clinical treatment paths against drug-resistant bacteria that cause fatal infections in the human body.

In the examination, it was observed that an antibiotic type named "Zosurabalpin" largely neutralized the drug-resistant "Acinetobacter baumannii" bacterium in a laboratory environment.

According to the US Centers for Disease Control and Prevention (CDC), the "Acinetobacter baumannii" bacterium, which has high resistance to currently used antibiotic types, causes serious and high-mortality infections in the lungs, urinary tract, and blood.

Battery-free sensor developed

Engineers at the Massachusetts Institute of Technology (MIT) in the US have developed a battery-free sensor that can generate its own energy for use in hard-to-reach areas.

When attached to an electric cable through which current flows, the battery-free sensor can generate its own energy by harvesting energy from the magnetic field created around the cable, providing information about power consumption in hard-to-reach parts of machines, such as a motor's power cable.

The heat sensor developed within the university does not require special installation or maintenance.

It is thought that this design could also be adapted to other power sources such as vibration and daylight, in addition to magnetic fields.

The Moon had more water in its crust when it first formed than previously thought

Scientists in the US, UK, Canada, and Sweden discovered that there was more water in the Moon's crust 4 billion years ago, as a result of research that changes general assumptions about the presence of water in the lunar crust.

In the study, the presence of apatite, known as the most common phosphate mineral, was detected in the Moon's primordial crust for the first time.

The finding obtained from apatite shows that there was much more water in the Moon's crust when it first formed than scientists had assumed, and it also sheds new light on its formative years.
