Lung Conditions and Liquid Ventilation
Humans have lungs adapted to inhale air and use the oxygen in that air which have served vertebrates since around 400Ma. Using liquid for ventilation in lungs would therefore seem absurd. Indeed, in normal healthy lungs, liquid breathing as one would expect worsens gas exchange. However, in cases of
The STEM Committee Science Exhibition
The STEM Committee's science exhibition captivated the audience with a whirlwind of hands-on science and mind-bending experiments. From exploring the hidden world of pixels to dissecting a sheep’s brain and testing memory, the night was filled with “wow” moments. From an intense battle between an at
Project CETI
Project CETI (Cetacean Translation Initiative), led by biologist David Gruber, is getting ever so close to bridging the gap between sperm whale ‘clicks’ and human words. Breakthroughs in artificial intelligence, especially in the use of machine learning techniques, have allowed algorithms to identif
The Rise of Superbugs and Antibiotic Resistance
Antibiotic resistance, driven by evolution, has become a critical global threat. The misuse of antibiotics in healthcare and agriculture accelerates the rise of resistant bacteria like MRSA. These "superbugs" lead to millions of infections and thousands of deaths each year.
Problem Of the Week: 20th September 2024
A hot air balloon uses a gas flame to heat the air it contains to a temperature required to enable it to hover at a small distance above ground level. The mass of the balloon, ropes, basket, and riders is 240 kg and the volume of the balloon is 1100 m³. The temperature of the surrounding air is 15°C
The Growing Role of Nanotechnology in Neurological Medicine
Nanotechnology is revolutionizing neurological medicine by enabling precise drug delivery and treatments. Techniques like PLGA and Cadmium Selenide nanoparticles bypass the blood-brain barrier, targeting conditions such as Alzheimer’s disease. With methods like lithography and vacuum deposition, the

A drunk performs a random walk along a street. At one end of the street is a river, and at the other end is a police station. If he gets to either of these ends, he remains there. He starts n steps from the river, and there are N total steps between the river and the police station. What is the prob
The Formation and Evolution of Neutron Stars
Neutron stars are born from the explosive deaths of massive stars, known as Type II supernovae. These dense celestial objects, only about 20 kilometers in diameter, possess extreme characteristics such as rapid spin rates and intense magnetic fields. The formation process involves complex nuclear re
