Losing, not violent content, triggers video game rage

Hostile behavior on the part of video gamers may be due to feelings of failure and frustration during play, rather than a game’s violent content. A new study is the first to look at the player’s psychological experience with video games instead of focusing solely on the game’s content. Failure to master a game and its controls can lead to frustration and aggression, regardless of whether the game is violent or not, researchers say. “Any player who has thrown down a remote control after losing an electronic game can relate to the intense feelings or anger failure can cause,” says lead author Andrew Przybylski, a researcher at the Oxford Internet Institute at Oxford University. That frustration is commonly known among gamers as “rage-quitting.” The experience is not unique to gaming, says coauthor Richard Ryan, a motivational psychologist at the University of Rochester. For example, in sports, players may lose a game as a result of a bad call. “When people feel they have no control over the outcome of a game, that leads to aggression,” he says. “We saw that in our experiments. If you press someone’s competencies, they’ll become more aggressive, and our effects held up whether the games were violent or not.” To tease out which aspects of the gaming experience lead to aggressive feelings, the researchers manipulated the interface, controls, and degree of difficulty in custom-designed video games across six lab experiments. Nearly 600 college-aged participants were tasked with playing the games—many of which included violent and nonviolent variations—and then were tested for aggressive thoughts, feelings, or behaviors.

Researchers at Lancaster University, UK have taken a hint from the way the human lungs and heart constantly communicate with each other, to devise an innovative, highly flexible encryption algorithm that they claim can’t be broken using the traditional methods of cyberattack.
Information can be encrypted with an array of different algorithms, but the question of which method is the most secure is far from trivial. Such algorithms need a “key” to encrypt and decrypt information; the algorithms typically generate their keys using a well-known set of rules that can only admit a very large, but nonetheless finite number of possible keys. This means that in principle, given enough time and computing power, prying eyes can always break the code eventually.
The researchers, led by Dr. Tomislav Stankovski, created an encryption mechanism that can generate a truly unlimited number of keys, which they say vastly increases the security of the communication. To do so, they took inspiration from the anatomy of the human body.

Four women have had new vaginas grown in the laboratory and implanted by doctors in the US.
A tissue sample and a biodegradable scaffold were used to grow vaginas in the right size and shape for each woman as well as being a tissue match.
They all reported normal levels of “desire, arousal, lubrication, orgasm, satisfaction” and painless intercourse.
Experts said the study, published in the Lancet, was the latest example of the power of regenerative medicine.
'I feel fortunate'
In each woman the vagina did not form properly while they were still inside their mother’s womb, a condition known as vaginal aplasia.
Current treatments can involve surgically creating a cavity, which is then lined with skin grafts or parts of the intestine.

What is consciousness? A neuroscientist’s new book argues that it arises when information is broadcast throughout the brain
Quantum physicist Wolfgang Pauli expressed disdain for sloppy, nonsensical theories by denigrating them as “not even wrong,” meaning they were just empty conjectures that could be quickly dismissed. Unfortunately, many remarkably popular theories of consciousness are of this ilk—the idea, for instance, that our experiences can somehow be explained by the quantum theory that Pauli himself helped to formulate in the early 20th century. An even more far-fetched idea holds that consciousness emerged only a few thousand years ago, when humans realized that the voices in their head came not from the gods but from their own internal spoken narratives.
Not every theory of consciousness, however, can be dismissed as just so much intellectual flapdoodle. During the past several decades, two distinct frameworks for explaining what consciousness is and how the brain produces it have emerged, each compelling in its own way. Each framework seeks to explain a vast storehouse of observations from both neurological patients and sophisticated laboratory experiments.

Results on regenerated thymus in very old mice potentially open way for helping humans live longer
Scientists have regenerated a living organ for the first time, potentially opening the way for life-lengthening human therapies.
A team at Edinburgh University’s medical research centre for regenerative medicine managed to rebuild the thymus of very old mice, re-establishing the health of the organ seen in younger creatures.
Scientists reactivated a natural mechanism that shuts down with age to rejuvenate the thymus, an organ near the heart that produces important infection-fighting white blood cells, called T cells.
By targeting a protein called FOXN1, which helps control how genes are switched on, the function of the thymus was restored. Treated mice began to make more T cells.
The research, published in the journal Development, found the thymus grew to twice its previous size, and the recovery appeared sustainable. Scientists now will look into any unintended consequences of increasing FOXN1.
The thymus is the first organ in the human body to deteriorate as we age, contributing to the declining capacity of older people to fight off new infections, such as flu.
The breakthrough may lead to treatments that could significantly elongate human life. But this would be many years away, given that the process has been tested only on mice.
