We sleep to forget things, new study finds

Sleep is as mysterious as it is vital for our wellbeing.

During REM sleep, memory is consolidated by weeding out unwanted neural connections

Sleep is very important for the brain. Here’s what happens during the most active phase of sleep.

How to make money in your sleep — just do it.

Is napping good or bad? Here’s what the science says so far

The benefits and downside of napping explained.

Brain circuit links sleep-wake cycle with reward system — a new potential target for insomnia drugs

A connection between reward and sleep has been found by neuroscientists. New drugs that target this circuit could help insomniacs ease into sleep.

We’ve finally discovered how birds can sleep and fly at the same time without crashing

Frigatebirds spend weeks at a time flying over oceans in search for food — here’s how they sleep during this time.

Caffeine is essentially useless after three sleep-deprived nights

After only three nights of sleeping five hours or less, caffeine stops working.

Working graveyard shifts puts your heart at risk

Those who work odd hours in shifts risk heart complications.

Can’t get any rest when sleeping in a new place? It’s just your brain keeping you safe

A new study offers insight into why you might have a hard time sleeping on the first night in a new place: half of your brain stays awake to watch out for potential dangers.

Being a morning person might be coded in your genes

Some people have no trouble rising early and being productive, while others are most active during the evenings. This begs the question: are morning persons and night owls set apart by habit or biology? Habits certainly play a leading role, but all things being equal your genes might have a strong word to say in the matter.

Our ancestors probably didn’t get more sleep than the average American

Researchers at University of California, Los Angeles (UCLA) surveyed hunter-gather communities in Africa and South America which practice a traditional lifestyle thousands of years old and found they slept an average of six hours and 25 minutes per night.

Kids everywhere, rejoyce – science says you should get those “5 more minutes, mom!”

A recent study performed by researchers working at the University of Oxford, Harvard Medical School and the University of Nevada suggests that the current school and university start times have a damaging effect on the learning and health of students.

No laughing matter: scientists study the effects of laughing gas

Nitrous oxide, commonly known as laughing gas, is a simple chemical composed of two nitrogen atoms and one oxygen atom (N2O). Despite being used as an anesthetic since the 1800s, the effects it has on the brain are not well understood. In a new study published in this week in Clinical Neurophysiology, MIT researchers reveal some key brainwave changes caused by the gas.

Is sleepwalking genetic? Study suggests it runs in the family

Canadian researchers found that kids born out of parents with a history of sleepwalking are more likely to experience somnambulism. They found 60% of kids whose both parents reported sleepwalking also took slumbering walks in the middle of the night, or seven times more likely than kids whose parents had no history of sleepwalking. Children with only one sleepwalking parent were three time more likely to sleep walk.

Study Confirms What Everyone Suspected: Teens Get Less and Less Sleep

US researchers have conducted a national survey and found that the percentage of U.S. teens who get seven or more hours of sleep is steadily decreasing. The number of teens suffering from sleep deprivation has continuously decreased, up to the point where less than half of all teens sleep adequately.

Sleep Scientists Suggest Starting Your Work Day a Bit Later

We’ve all experienced it – waking up early in the morning can be really hard, and even if you do wake up, you’re just not productive; and then, in the night, you just can’t go to sleep – you stay up too late, it gets even harder to wake up the next day and the cycle continues. Now, a group

What the World looks like when the Internet is asleep

There are over 4 billion IP addresses registered all over the globe and this number is constantly growing as developing countries get wired and more people use smartphones and tablets. The internet isn’t the same all over the world (yet) and activity heavily fluctuates from day to night. A new study mapped the world’s internet activity using an extremely simple

Automated tasks are still processed while you sleep

Despite an incredible body of work dedicated to researching what goes inside the brain while we sleep, consensus among neuroscientists suggests we’re just beginning to scratch the surface. For instance, we’ve yet to answer a fundamental question: why do we need sleep? We all agree that we needed it  – going without sleep for long periods of time can bring

Newly discovered ‘sleep node’ in the brain puts you to sleep without sedatives

Neuroscientists at University of Buffalo have identified a sleep-promoting circuit inside the brainstem or the primitive part of the brain, whose activity appears to be both necessary and sufficient to produce deep sleep. This is only the second ‘sleep node’ in the mammalian brain that was identified to serve this function. To demonstrate the sleep node’s function, the researchers used
