RNA interference: the molecules that govern genetic control

Posted on

Introduction Humans are highly complex, multicellular organisms with millions of cells specialised for particular functions via distinct morphologies and chemistry. The process by which various cell types are generated from one universal type during development is known as cellular differentiation, and is driven by changes in gene expression in response to environmental changes. Different patterns […]

Martha Chase: The Underappreciated Geneticist

Posted on

Martha Chase was an American geneticist. In 1952, during the “Hershey-Chase Experiments,” she accompanied Alfred Hershey, helping to experimentally confirm that DNA, not protein, is the genetic material of life [1]. This discovery was awarded the Nobel Prize in Physiology or Medicine in 1969, yet excluded Chase [2]. There is not much information about the […]

The Genetics of Bird Migration

Posted on

  Introduction People have always noticed the effects of migration even if they were unaware of the cause. Rock art with drawings of the birds have survived and there are paintings in Egyptian tombs depicting birds such as cranes (from the north) and white-breasted geese which nest in the Arctic. These species could only have […]

by Alyssa Khoo Abstract Emotions play one of the most integral roles in human experience and yet are often considered one of the most enigmatic to explain scientifically.[1] Evolutionarily speaking, emotions contribute greatly to the ability to survive. For instance, fear would trigger an almost instantaneous ‘fight or flight’ response to allow an individual to […]

To Sleep or Not To Sleep?

Posted on

Hiu Yu Wong Try explaining the state of sleeping to an alien. “We spend a third of our lives lying down without perceiving the environment around us, and sometimes there’ll be imaginary stories happening in our head…” Indeed, the act of sleeping sounds absurd and impractical. Why do we waste our time on our bed […]

AI and biological consciousness – is there a connection?

Posted on

Lucy Chen Artificial intelligence has existed since the 1950s, and underpins all technology in modern society. From monitoring Amazon transactions to self-driving cars, almost every product used today runs on intelligent machines. One of the most recognisable systems of artificial intelligence is the artificial neural network (ANN), which is loosely modelled after the animal neocortex- […]

CAN THE DE BROGLIE RELATION BE MODIFIED FOR ACCOMMODATING RELATIVISTIC MODIFICATIONS IN THE SCHRÖDINGER EQUATION?

Posted on

  by Arpan Dey Abstract The main objective of the present paper is to investigate the de Broglie relation [1] and determine its consequences on the time-independent Schrödinger equation [2], and whether the results are valid in terms of accommodating relativistic corrections in the Schrödinger equation. The de Broglie relation has been modified by considering […]

Oumuamua : A Cigar Shaped Puzzle

Posted on

Asteroids are essentially rocks in space that form the protoplanetary disk of dust and gas forming a ring about the sun. Their sizes can range from those as small as boulders and those which are as large as planets. During the early days of our solar system, debris was unstable, crashing and colliding with one […]

World Asteroid Day: What, when and why

Posted on

On an early morning more than a century ago, a ‘fireball bright as the Sun’ exploded midair, flattening about 2150 sq. kilometers of land near the Podkamennaya Tunguska River in Russia. 80 million trees were demolished. Seismic and pressure waves were felt around the world, and people reported having bright nights, being able to read […]

New Technological Solutions to the Staging of cancer 1.1 Cancer Types What is Cancer: Cancer is a terminal disease caused by the uncontrolled growth of cells. While regular cells proliferate in a controlled manner, cancer cells proliferate uncontrollably due to a loss of cell cycle control systems. Cancers are not well understood, because there are […]
