- Imagining walking through a doorway triggers increased forgetting
We’ve all had that experience of going purposefully from one room to another, only to get there and forget why we made the journey. Four years ago, researcher Gabriel Radvansky and his colleagues stripped this effect down, showing that the simple act of passing through a doorway induces forgetting. Now psychologists at Knox College, USA, have taken things further, demonstrating that merely imagining walking through a doorway is enough to trigger increased forgetfulness
- Beer compound could help fend off Alzheimer’s and Parkinson’s diseases
One compound found in hops, called xanthohumol, has gotten the attention of researchers for its potential benefits, including antioxidation, cardiovascular protection and anticancer properties.
- Psychopathic violent offenders’ brains can’t understand punishment
“Psychopathic offenders are different from regular criminals in many ways. Regular criminals are hyper-responsive to threat, quick-tempered and aggressive, while psychopaths have a very low response to threats, are cold, and their aggressively is premeditated,” added Dr. Nigel Blackwood, who is affiliated with King’s College London. “Evidence is now accumulating to show that both types of offenders present abnormal, but distinctive, brain development from a young age.”

A large study links a significantly increased risk for developing dementia, including Alzheimer’s disease, to taking commonly used medications.
- Scientists discover ‘dimmer switch’ for mood disorders
Researchers at University of California, San Diego School of Medicine have identified a control mechanism for an area of the brain that processes sensory and emotive information that humans experience as “disappointment.” The discovery of what may effectively be a neurochemical antidote for feeling let-down is reported in the online edition of Science.
- How creative are you? Depends where you’re from
With the “creative class” on the rise, many businesses are trying to capitalize on imagination and innovation. But when it comes to creative juices, some societies have a faster flow than others. That’s because, as new research from Concordia University suggests, creativity is tied to culture.

In the study, the researchers show that when mice receive a supplement of ghrelin, they increase their sexual activity and their efforts to find a partner.
- Neuroscience researchers believe in quitting smoking gradually
The brain’s oxygen uptake and blood flow decreases by up to 17% immediately after people stop smoking: Regular smokers experience an almost dementia-like condition in the early hours after quitting, as suggested by brain scans.

In the US and many Western countries, people are urged to manage feelings of anger …
- Was Beethoven’s music literally heartfelt?
The striking rhythms found in some of Beethoven’s most famous works may have been inspired by his own heartbeat, says a team of researchers from the University of Michigan and University of Washington that includes a cardiologist, medical historian, and musicologist.
- Withdrawal or expecting your lover to mind-read hurts relationships, but in different ways
“Withdrawal is the most problematic for relationships,” Sanford said. “It’s a defensive tactic that people use when they feel they are being attacked, and there’s a direct association between withdrawal and lower satisfaction overall with the relationship.”
Meanwhile, “passive immobility” — expecting your partner to be a mind-reader — is a tactic people use when they feel anxious in a relationship, and it makes it especially difficult for couples to make progress toward resolving conflicts. But it may not be as harmful down the line as withdrawal, he said.
- Humans erode soil 100 times faster than nature
A new study shows that removing native forest and starting intensive agriculture can accelerate erosion so dramatically that in a few decades as much soil is lost as would naturally occur over thousands of years.
- Researchers find significant link to daily physical activity, vascular health
The researchers found that reducing daily physical activity for even a few days leads to decreases in the function of the inner lining of blood vessels in the legs of young, healthy subjects causing vascular dysfunction that can have prolonged effects.
- Finding the simple patterns in a complex world
An ANU mathematician has developed a new way to uncover simple patterns that might underlie apparently complex systems, such as clouds, cracks in materials or the movement of the stockmarket.

Adding just one gram of turmeric to breakfast could help improve the memory of people who are in the very early stages of diabetes and at risk of cognitive impairment.
- For leaders, looking intelligent is less important than looking healthy
People look for candidates with a healthy complexion when choosing a leader, but don’t favor the most intelligent-looking candidates except for positions that require negotiation between groups or exploration of new markets.
- Training can lead to synesthetic experiences, study shows
A new study has shown for the first time how people can be trained to “see” letters of the alphabet as colours in a way that simulates how those with synaesthesia experience their world.
The University of Sussex research also found that the training might potentially boost IQ.
- Why you’re particularly likely to run your first marathon when your age ends in a “9”
According to the psychologists Adam Alter andHal Hershfield, when our age ends in a “9”, such as 29, 39, 49 or 59 – we are particularly prone to reflect on the meaning of our lives. If we don’t like what we see, their new results suggest we take drastic action, either fleeing life’s emptiness, or setting ourselves new goals.
- Mindfulness techniques can help protect pregnant women against depression
Pregnant women with histories of major depression are about 40 percent less likely to relapse into depression if they practice mindfulness techniques–such as meditation, breathing exercises and yoga–along with cognitive therapy, according to a new study.

- Only half of patients take their medications as prescribed: are there interventions that will help them?
Only about half of all patients who are prescribed medication that they must administer themselves actually take their medication as prescribed. Many stop taking medication all together and others do not follow the instructions for taking it properly. This has been the case in many different diseases for at least the last half a century
- Many older brains have plasticity, but in a different place
A new study led by Brown University researchers contradicts that notion with a finding that plasticity did occur in seniors who learned a task well, but it occurred in a different part of the brain than in younger people.
- New solar power material converts 90 percent of captured light into heat
The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity.
- Australian scientists propose existence and interaction of parallel worlds
The team says that parallel universes really exist, and that they interact. And rather than evolving independently, nearby worlds influence one another by a subtle force of repulsion. They show that such an interaction could explain everything that is bizarre about quantum mechanics
- Can love make us mean?
Empathy is among humanity’s defining characteristics. Understanding another person’s plight can inspire gentle emotions and encourage nurturing behaviors. Yet under certain circumstances, feelings of warmth, tenderness and sympathy can in fact predict aggressive behaviors, according to a recent study.
- High-fat diet postponing brain aging
New Danish-led research suggests that signs of brain aging can be postponed in mice if placed on a high-fat diet. In the long term, this opens the possibility of treatment of children suffering from premature aging and patients with Alzheimer’s and Parkinson’s disease
- Why women buy magazines that promote impossible body images
Some readers, rather than comparing themselves unhappily with the thin models, may derive “thinspiration”: the belief that they can make themselves look just as attractive as the models they see in these magazines.
