New Step In Genetic Modification Of Plants

by Geetanjali Yadav in United Academics

Plant transformation is insertion of new genetic material to the plant’s body. This used to be difficult because many economically important plants are recalcitrant to it as they lack certain gene elements. But according to a recent report published in Science, researchers now have successfully transformed a model plant, Arabidopsis, through agrobacterium-mediated transformation process.... Read more »

Collective Memory: Scientific Aproach To Telepathy

by Katja Keuchenius in United Academics

Why do humans often make independent but similar discoveries at about the same time? What makes us repetitively stumble upon that new word or phenomenon that we just learned about the other day? And how do mice know all about our poison and traps? Is it because all members of a species share a thelapethic-like collective memory?... Read more »

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 »

Slacktivism | Procrastination or Giving up?

by Patrícia Fonseca Pedro in United Academics

PhD student Kirk Kristofferson acknowledged that each “Like” or “Share” push us further away from meaningful support. For each of these actions, most people feel that their mission is “accomplished”. “Our research shows that if people are able to declare support for a charity publicly in social media it can actually make them less likely to donate to the cause later on.” Kristofferson reinforces....

5 Health Claims About Hot Yoga: True Or False

by Elisabeth Buhl Thubron in United Academics

The instructors themselves often refer to science to explain miracle cures and healing effects of hot yoga. As a scientist, I am reluctant to believe much of what is said. Is there really any truth in the 5 health claims or is it just all a marketing tool?... Read more »

You Use Nanoparticles Everyday: 4 Examples

by Chiara Civardi in United Academics

Whatever our opinion on nanotechnology may be, what we don’t realise is that we are exposed to nanoparticles in our everyday life, not only through pollution, but by means of the products we use daily. So, here’s a short list of some of these hidden engineered nanoparticles.... Read more »

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 relationships tell us about human relationships. Is romance and monogamy nothing but a myth?... Read more »

Does Modern Life Make Us Less Rational?

by Flora Brils in United Academics

If you give a Westerner one of two items randomly and then ask the person whether he or she would like to trade one for the other, there is only 10 percent chance the Westerner trades. This doesn't make sense, or at least it's not rational. There should be a 50 percent chance that participants initially receive the item they like best and thus a 50 percent chance that they will trade. This behavioral bias is called the “endowment effect”. A new interdisciplinary study from the University of Pennsylvania has delved into whether this bias is truly universal... Read more »

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 »

Masculine Men Experience Greater Sexual Satisfaction

by Eva de Lozanne in United Academics

Initially, researchers S. Daniels and S.K. Bridges hypothesized that masculinity would relate negatively to sexual satisfaction. The ideal of masculinity, the researchers explain, teaches men that they should be directive, dominant, assertive and independent. They assumed that higher levels of these “masculine traits” would get in the way of men’s subjective and emotional satisfaction during sex.... Read more »

Serious Gaming, Serious Fun?

by Nura Rutten in United Academics

Serious gaming is big business. Many organizations – companies, schools, NGO’s – use games for training purposes, to engage customers, to advertise and to simulate important and critical situations. It is likely that you have been playing a game that was designed with the purpose of teaching you something, getting you to drink more milk or training your cooperative skills.

Researchers Liu, Li, and Santhanam have studied the way in which different digital games impact the behavior and emotion responses of the players. Their study addresses one key element of gaming: competition. Players seem to favor opportunities to compete with each other and games where there is a challenge. Therefore, their research attempts to analyze the influence of competition on the effort that participants put into their play and their enjoyment.... Read more »
