God’s Existence Theorem Is Correct

by Simone Munao in United Academics

“If God is possible, then he exists necessarily. But God is possible, therefore he exists”. This is the extreme synthesis of Gödel’s most famous result. Two researchers -Christoph Benzmuller and Bruno Woltzenlogel Paleo- just confirmed the result thanks to the help of a computer-assisted proof.... Read more »

You Use Nanoparticles Everyday: 4 Examples

Biology of Love: are we made to live happily ever after?

by Koko Beers in United Academics

While we learn from songs, movies and fairy tales that life is all about finding the perfect partner, about romance, soul mates and lifelong relationships; biology tells us otherwise.

Neuroscientists and neurobiologists have looked at the neuronal correlates of love, using brain imaging techniques and animal models. Reviewing various studies, Dutch researchers explain the evolution and neurobiological factors of our romantic love. Learn what evolution, biological substances and the course of ........

How To End HIV in Africa

by Patrícia Fonseca Pedro in United Academics

South Africa is known to have a major burden of HIV infection cases. As Pieter Fourie put it in 2006: “AIDS is killing South Africans at a rate equivalent to one September 11th attack every three days”. The situation still is as serious as this: life expectancy should have reached 64 years by now, but with the HIV pandemic it has regressed to about 47 years.... Read more »

When equipment fails: paws and assess

by Cobb & Hecht in Do You Believe In Dog?

Photo: Steven PamThere is an industry in Australia that relies on an integral piece of equipment, but the system behind product development process is flawed, and lives are at stake. From farm dogs to military explosive detection dogs, guide dogs to greyhounds, Australia’s working and sporting dog industry claims a 50-70% fail rate as normal. The welfare of these dogs is intimately linked to their working performance. It can be an emotive topic, so let’s take the emotion out of it and o........ Read more »

To Call a Player’s Poker Hand, Look to the Arms

by amikulak in Daily Observations

Professional poker players rely on the ability to divorce their facial expressions from their emotional state – no matter how good, or how bad, their hand is, they have to maintain an inscrutable “poker face.” But new research suggests that they may do well to focus on another body part: The arms. The research, published in Psychological Science, suggests that homing in on only the player’s arms may be the most reliable way to call a bluff.... Read more »

The Selective Clearance of Senescent Cells – a Promising Target for Ageing

by Robert Seymour in NeuroFractal

When cells are put under stress (e.g. UV light, ionising radiation, reactive oxygen species) they undergo a process known as cellular senescence in which cell division (mitosis) is arrested. This is thought to contribute to ageing. In their 2013 paper Naylor and colleagues outline a strategy to selectively remove in vivo senescent cells expressing p16Ink4A .... Read more »

Researchers Discover Link Obesity And Liver Cancer

by Pieter Carrière in United Academics

Is life worth living? It all depends on the liver, postulated ‘Father of American psychology’ William James (1842-1910). His famous quote underlines the central role the liver plays in detoxification, digestion of lipids, storage of nutrients to maintain homeostasis and so on.

Sadly, liver cancer is one the most common cancers worldwide, with 750.000 new patients each year and presumably causing almost 700.000 deaths annually. These figures reveal that liver cancer is extremely le........ Read more »

Violence Against Women Starts With School Stereotypes

by Nancy Lombard in United Academics

Gender based violence is a deeply embedded problem in many societies and cultures. Despite this, efforts to challenge it are rarely seen at a primary school level. There is a perception that children aged 11 and 12 are too young to “know” about violence, or to offer opinions on it. But this is something that has to change if we are ever going to combat the attitudes and behaviour that can lead to this type of violence.... Read more »
