In recent years, engineers in Australia have made remarkable progress in developing a small ammonia gas sensor. This sensor, a simple but highly effective proof-of-concept, has the potential to revolutionize various industries. Collaboratively built by researchers at RMIT University, the University of Melbourne, and the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS), this
Spiral galaxies have an enchanting quality that captures the imagination of anyone fascinated by the wonders of Nature. Recently, the James Webb Space Telescope (JWST) captured incredible images of 19 spiral galaxies, providing a mesmerizing display of their intricate details. These images were obtained as part of the Physics at High Angular resolution in Nearby
Simulating miniaturized versions of human organs in the lab has emerged as a pivotal tool in medical research. Recently, a team of researchers from Cedars-Sinai Medical Center in Los Angeles unveiled their groundbreaking “heart-on-a-chip” model. This model is poised to revolutionize the testing of cancer treatments, particularly those that pose a risk of heart damage.
Researchers at Tata Institute of Fundamental Research (TIFR) in Mumbai have made a groundbreaking discovery in the field of catalyst development. Led by Prof. Polshettiwar, the team has successfully created a “plasmonic reduction catalyst stable in air” that surpasses the limitations of traditional reduction catalysts. This innovative catalyst combines platinum-doped ruthenium clusters and “plasmonic black
The Food and Drug Administration (FDA) is sounding the alarm on tianeptine, a synthetic drug commonly known as “gas station heroin.” While some countries approve tianeptine as a prescription drug for depression, it poses serious health risks resembling those of opioids like fentanyl. Despite FDA warnings, this drug continues to be promoted and sold as
Cosmic rays, high-energy particles that reach Earth from outer space, have long remained a scientific enigma. However, recent findings suggest that a small black hole known as SS 433 may hold the key to understanding the origin and acceleration of these mysterious cosmic rays. In this article, we will delve into the details of this
Exercise plays a crucial role in maintaining a healthy lifestyle, especially as we age. Older adults are often encouraged to find a fitness routine that suits their needs and preferences. However, a recent study conducted by researchers from Nanyang Technological University (NTU) in Singapore suggests that exercising as a couple may have a negative impact
The administration of growth hormone extracted from deceased individuals to treat short stature in children was discontinued due to the emergence of Creutzfeldt-Jakob disease. However, recent research suggests that these injections may have also contributed to the development of Alzheimer’s disease. This article examines the implications of person-to-person transmission of Alzheimer’s and the potential risks
The human brain is a complex organ that plays a vital role in our daily lives. It is the body’s control center and is responsible for our thoughts, emotions, and actions. To protect this precious organ from pathogens and toxins, the brain and spinal cord are shielded by a barrier known as the blood-brain barrier.
Japan’s Moon lander, the Smart Lander for Investigating Moon (SLIM), has recently sent back its first images of the lunar surface, providing a detailed view of the gray, rubble-covered world. However, this beautiful and lonely view is also a poignant reminder of the unfortunate situation that the lander finds itself in. Just moments after capturing
Cancer, a deadly disease that affects millions of people worldwide, is characterized by the uncontrolled growth and spread of abnormal cells. Researchers have long been studying the protein MYC, which plays a crucial role in both healthy cell activity and cancer development. MYC, when functioning normally, helps regulate cell growth and division. However, in cancer
In a remarkable medical breakthrough, history was made in 2022 when surgeons performed the world’s first partial heart transplant in a baby. The recipient, Owen Monroe, who was just 18 days old at the time, underwent a groundbreaking procedure where heart valves and vessels taken from a donor infant were stitched into his heart. This
Ageing is an inevitable part of life, and humans have always been fascinated with the quest for longevity.
