New research shows that the drug makes cells in the retina more sensitive to light

25 years ago, pharmacologist M. E. West of the University of the West Indies in Kingston, Jamaica, noted that local fisherman who smoke cannabis or drink rum made with the leaves and stems of the plant had “an uncanny ability to see in the dark,” which enabled them to navigate their boats through coral reefs. “It was impossible to believe that anyone could navigate a boat without compass and without light in such treacherous surroundings,” he wrote after accompanying the crew of a fishing boat one dark night, “[but] I was then convinced that the man who had taken the rum extract of cannabis had far better night vision than I had, and that a subjective effect was not responsible.”

Some of these crew members told West that Moroccan fishermen and mountain dwellers experience a similar improvement after smoking hashish, and in 2002, another research team travelled to the Rif mountains in Morocco to investigate further. They gave a synthetic cannabinoid to one volunteer, and hashish to three more, then used a newly developed piece of kit to measure the sensitivity of their night vision before and after. Confirming West’s earlier report, they found that cannabis improved night vision in all three of their test subjects.

It’s not just your waistline that suffers as you put on weight. Researchers are beginning to find puzzling new links between obesity, memory loss and dementia

Lucy Cheke and her colleagues at the University of Cambridge recently invited a few participants into her lab for a kind of ‘treasure hunt’.

The participants navigated a virtual environment on a computer screen, dropping off various objects along their way. They then answered a series of questions to test their memory of the task, such as where they had hidden a particular object.

New research shows that the rhythm of breathing directly impacts neural activity in a network of brain areas involved in smell, memory and emotions

The rhythm of breathing co-ordinates electrical activity across a network of brain regions associated with smell, memory, and emotions, and can enhance their functioning, according to a new study by researchers at Northwestern University. The findings, published in the Journal of Neuroscience, suggest that breathing does not merely supply oxygen to the brain and body, but may also organise the activity of populations of cells within multiple brain regions to help orchestrate complex behaviours.

New research provides evidence for the idea that sleep restores cellular homeostasis in the brain and helps us to forget irrelevant information

We spend one third of our lives sleeping, but we still do not know exactly why we sleep. Recent research shows that that the brain does its housekeeping while we sleep, and clears away its waste. According to another hypothesis, sleep plays the vital role of restoring the right balance of brain synapses to enhance learning, and two studies published in today’s issue of Science now provide the most direct evidence yet for this idea.

We do know that sleep is important for consolidating newly formed memories. During waking hours, we learn all kinds of new information, both consciously and unconsciously. To store it, the brain modifies large numbers of synaptic connections, making some of them stronger and larger, and it’s now thought that as we sleep other synapses are weakened or destroyed, so that the important new information is stored for later use, while irrelevant material, which could interfere with learning, is not.

New research shows that we can train our brains to become memory champions

To many of us, having to memorize a long list of items feels like a chore. But for others, it is more like a sport. Every year, hundreds of these ‘memory athletes’ compete with one another in the World Memory Championships, memorising hundreds of words, numbers, or other pieces of information within minutes. The current world champion is Alex Mullen, who beat his competitors by memorizing a string of more than 550 digits in under 5 minutes.

You may think that such prodigious mental feats are linked to having an unusual brain, or to being extraordinarily clever. But they are not. New research published in the journal Neuron shows that you, too, can be a super memorizer with just six weeks of intensive mnemonic training, and also reveals the long-lasting changes to brain structure and function that occur as a result of such training.

My friend the dumb joe will ask me for money and try and sell me his garbage because he needs money for a bus fare. He will talk to Asian girls because I think he is not good enough for white girls. He try's to many things. Let's go over some of them. The army the police an astronaut he worked at 5 different supermarkets he got a night job for about 3 weeks and never sleeper at all. He wanted to go to China but cancelled he wanted to go to Auckland but cancelled he wanted to go to Singapore but cancelled. He brought a moped and sold it a week later. He wanted a BMW but didn't get one after he told me he was getting it. He sold me a speaker for $20 and a month later he asked for it back for free and he did not get it. He was on his way to buy a computer and he runs in to a friend and asked him can I have your computer for $200 when the one he was going to buy was $180. He will never learn to drive when he drove into a lamppost. And meny more weird things as well. What is wrong with him?

I think The Rock is a combination of both but barely because when he made his debut in the WWF in late 1996, he wasn't even called The Rock yet he was Rocky Maivia at that time. By the time he started getting over with the fans as The Rock, the 90s were almost over because it was 1998 - 99 by then. He spent more time as The Rock in the 2000s but even though he was still in the WWF/E when the decade started, he was gone by 2004 (by then he was already doing movies and wrestling at the same time). Then The Rock stopped wrestling completely and spent the rest of the 00s decade making movies, he spent even less time wrestling in the 2010s which is his most recent run in the WWE he missed 2010, came back in 2011 and was gone by 2013 aside from one match in 2016. What do you guys think ?

I am a dog sitter for my sister, she pays me around $100 a week. I also do extra chores around the house such as cleaning as an exchange for not paying rent. The money she pays me is usually transferred through zelle or paid cash. Im not sure if I would be considered an independent contractor or an employee. Also does she have to report to the irs my income and what forms would she have to use? Ive always received w2s from employers, so I’m Clueless to what I should do this tax season.  Thank you in advance!  Sorry I forgot to mention that my income for this last year was approximately $5000

Examples being: XTro (UK), Oldboy (S.Korea), Girl With a Dragon Tattoo (Sweden), Predestination (Australia) ... something like these

I’ve liked him for a year and I told him, but he told me to date someone else. I started to forget about him, but then he told me that he liked me too. We’re dating now but I don’t think that I feel the same was as when I first started liking him. What should I do?

I just got sent an electronic message from one of the employers stating that I am unsuitable for the role based on my police record. I'm under the impression some people are still choosing to impersonate me on several job search engines by giving each employer the idea I'm an ex-con with work skills that came out of prison. Is there a chance they can see my old name?

is she thicc af? I made this in the Sims 4 lol 

Feminism is a lie and useless in modern America, patriarchy is a good thing and natural order of society. Women be like I'm oppressed cause I don't always get my way and choose careers that pay less

....GOING TO DO WHEN THEY BELIEVE THEY APPLY TO THEM BUT THEY HAVEN'T BEEN HOLY SPIRIT BAPTIZED? TODAY'S CHRISTIANS HAVEN'T BEEN "QUICKENED BACK TO LIFE" (EPHESIANS 2:1)  BY HIS "POWER THAT CAME UPON THEM" (ACTS 1:8) WITH HOLY SPIRIT BAPTISM (ACTS 1:5) AS THEY WERE "BORN AGAIN OF THE SPIRIT" (JOHN 3:5-7) FROM THEIR "DEAD SPIRITS" (ROMANS 5:12-14) AND WERE "RESURRECTED" (I COR 15) FROM THEIR GRAVES" (EZEKIEL 37:12-14). WHAT ARE THESE "DEAD SPIRITS" GOING TO DO? 

I have a fwb trade with this guy who doesnt respect me at all and hurts my feelings because I'm not as attractive as he is and gets annoyed if I dont meet his demands,how do I stop this fwb? I'm scared if he does he'll tell people or get mad at me.

I'll try to keep this short: So I have always dated guys. Yet when I am not dating guys, my best friend and I; who's a girl, hook up. We've been doing this for about 5 years, we met at the age of 15, and 5 yrs later I had my first lesbian experience with her, and then 5 years it became a fairly regular thing. 5 years is obviously a long time. But when I'm not dating a guy, I always go back to her. And she's the only woman I have ever been with. That's why I am confused about this. I do not know if I'm straight or a lesbian?

So I was talking to this cute Christian girl and she was apparently interested in me. We even set up a date and aal that. Then she found out I'm an atheist, and she said that "She's looking for someone to share her faith" and bailed out on me. Why does God want me to kiss his a ss so badly, for me to simply date a girl? Does he have a perverted crush on me?

yesterday night i had come from the cold and i was freezing!. i immediately got into a hot shower - i don't know why but i started feeling dizzy: my vision started going and i was confused then my ears started ringing and i was scared. i shouted for someone and my brother came: he asked if i was ok but i said i felt dizzy and i couldn't really see him at all. i said i felt faint and he said sit down slowly - so i did. eventually i closed my eyes and it helped; i feel better now but why did it happen?!.
