Researchers have shown that non-invasive magnetic pulses can reset unhealthy activity in a region of the brain known to be overactive in patients with depression.
The technique is known as transcranial magnetic stimulation (TMS), and has been shown to treat persistent depression, as well as boost people’s memories, aid Parkinson’s sufferers, and help stroke patients to speak again.
Experiencing “senior moments” may be a good sign rather than a cause for concern, research suggests. The time to worry is when you begin to stop noticing memory lapses, scientists have shown.
A study, published in the journal Neurology, found that people with dementia tended to lose awareness of memory problems two to three years before the condition developed.
You’re about to switch lanes on a busy road when you realize there’s a car in your blind spot. You have to put a stop to your lane change — and quickly. A new study suggests that this type of scenario makes a person less likely to remember what halted the action — for example, the make and model of the car in the blind spot.
Consider, if you will, your favorite neurotic. You may need to look no further than across your breakfast table, or conjure a picture of the nation’s neurotic laureate — Woody Allen. Or perhaps you’d reach back in history, say, to Isaac Newton — father of calculus, discoverer of the universal laws of motion, and a world-class neurotic. Throughout his long life, Newton was angry, secretive, thin-skinned, guilt-ridden and prone to fits of melancholy.
An Opinion piece published Thursday invites you to consider why your favorite neurotic is more likely than his or her sunny opposite to be creative.
An experiment heading up next week to the space station could help landlubbers down here on Earth conserve water by doing a better job of filtering out chemicals, salts or other contaminants. It could even be a lifesaver for drought-stricken Californians who are desperate for new sources of water.
With the speculative possibility of a sentient machine, can we assume that Artificial Superintelligence would “take drugs” or “get high”? Hopes&Fears looked toward researchers at Rensselaer AI & Reasoning Laboratory, as well as Dr. David Brin, a fellow at Institute for Ethics and Emerging Technologies, for the answer.
A single dose of cocaine can interfere with your ability to recognise other people’s emotions.
According to new research, the drug can damage social awareness, and can stop users from being able to process negative feelings such as anger, irritation or sadness. So, in other words, the reason you think you’re so confident and social when you’re high is because you just aren’t able to process how annoyed everyone is with you.
As astronomical techniques become more advanced, a team of astrophysicists think they will be able to not only detect the signatures of alien life in exoplanetary atmospheres, but also track its relentless spread throughout the galaxy.
The research, headed by Henry Lin of the Harvard-Smithsonian Center for Astrophysics (CfA), assumes that this feat may be possible in a generation or so and that the hypothesis of panspermia may act as the delivery system for alien biology to hop from one star system to another.
According to our current model of the universe, we’re all trapped inside a prison we can never escape. We just haven’t noticed yet—because the prison is about 91 billion light-years in diameter. We haven’t developed the technology to even get a good look at it, much less travel within it, much less reach the edge. But one day in the far-flung future, it will be very, very important that we escape it. Because this universe, most physicists predict, will one day become uninhabitable.
Dark matter—the unseen 80 percent of the universe’s mass—doesn’t emit, absorb or reflect light. Astronomers know it exists only because it interacts with our slice of the ordinary universe through gravity. Hence the hunt for this missing mass has focused on so-called WIMPs—Weakly Interacting Massive Particles—which interact with each other as infrequently as they interact with normal matter.
Subatomic particles have been found that appear to defy the Standard Model of particle physics. The team working at Cern’s Large Hadron Collider have found evidence of leptons decaying at different rates, which could possibly point to some undiscovered forces.
Publishing their findings in the journal Physical Review Letters, the team from the University of Maryland had been searching for conditions and behaviours that do not fit with the Standard Model.
Scientists think they have a pretty good idea of how old the Universe is, but its age can depend on exactly where you are in it. Because of the time it takes for light to travel, observers on a planet other than Earth could well come up with a different calculation.
Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classical physics–the laws and principles that appear to explain the physics of relatively large objects at human scale. However, quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale, state that nothing can quite be completely at rest.
Shortening the school week to four days has a positive impact on elementary school students’ academic performance in mathematics, according to researchers at Georgia State University and Montana State University.
The researchers found a four-day school week had a statistically significant impact on math scores for fifth-grade students, while reading scores were not affected.
The past several years have been bruising ones for the credibility of the social sciences. A star social psychologist was caught fabricating data, leading to more than 50 retracted papers. A top journal published a study supporting the existence of ESP that was widely criticized. The journal Science pulled a political science paper on the effect of gay canvassers on voters’ behavior because of concerns about faked data.
If you stuck to Aesop’s fables, you might think of all ants as the ancient storyteller described them—industrious, hard-working, and always preparing for a rainy day. But not every ant has the same personality, according to a new study. Some colonies are full of adventurous risk-takers, whereas others are less aggressive about foraging for food and exploring the great outdoors.
A closer look at how honey bee colonies determine which larvae will serve as workers and which will become queens reveals that a plant chemical, p-coumaric acid, plays a key role in the bees’ developmental fate.
The study, reported in the journal Science Advances, shows that broad developmental changes occur when honey bee larvae – those destined to be workers – are switched from eating royal jelly (a glandular secretion) to a diet of jelly that includes honey and beebread (a type of processed pollen).
