When people offer the colloquialism “It will make you feel young again,” they are often describing the short-term spike in energy following a particular activity. Whether it’s the euphoria of riding a rollercoaster or the caffeine boost from a double-shot of espresso, the feeling usually dissipates, making the saying somewhat ironic. One of the distinct marks of youth is constant energy that returns not long after it fades.

Although Father Time remains undefeated, there is more good news for current members of Generation Active. The lifestyle trends of consistent exercise bode well for heart health and the sustained bouts of energy that diminish in old age, according to a recent study published in the Journal of Applied Physiology.

The researchers at Ball State University who conducted the study analyzed the health of the heart, lungs, and muscles among a group of individuals in their 70’s and found that their state was comparable to those of people in their 40’s.

To add, exercise also has potential to stave off dementia and age- related cognitive decline— Aka keeps your nervous systems “young” as well

Simple resistance exercises have enormous benefits, especially for seniors. A substantial portion of admissions (1/3 I think) to nursing homes is due to frailty, as opposed to actual disease, that can be avoided through modest weight lifting.

​

And then the benefits of aerobic exercise are huge for not just cardiovascular health, but for mental health too.

weight lifting is so underrated even in most commercial gyms and its benefits can not be repeated enough times

Researchers in Finland have made the first-ever vaccine for insects, aimed at helping struggling honeybee populations against American Foulbrood, a bacterial infectious disease. The Finnish team calls their vaccine PrimeBEE, and they say it can be delivered to the queen via a sugar patty.

Check out Paul Stamets on YouTube. He’s a mycologist that found certain mushrooms are sought out by bees as an antibiotic source.

If this breaks through its safety tests, this will be incredible! I wonder about its long term effects though, since the protein they are targeting to immunize the bees also appear to regulate behaviors from nursing to foraging, and other social processes within the hive. Not to mention, how long does the vaccine last in the queen bee? Does each new queen need to be revaccinated?

This is the first time researchers have successfully attempted to vaccinate a honeybee, but with their dwindling population, it’s extremely dangerous to mess up here on unexpected long term problems. I genuinely hope these vaccines work as intended and continue to do so generations of honeybees later.

Something most people don't realise, the American honey bee is an invasive species brought over during exploration and expanding periods of Europe. Their being here actually destroys hundreds of other bee species that are better for the earth. And almost all of them are harmless to humans as well. Some can't even fly.

Researchers tested more than 500,000 chemical compounds for their ability to inhibit the malaria parasite at an earlier lifecycle stage than most current drugs, finding 631 promising ones that could form the basis for new malaria prevention drugs, which they are making open source and not patented.

I have a lot of respect for researchers who make their work open source and don't patent it. Especially if it will help to lessen human suffering.

The nobility of the gesture is honestly the closest thing to superhero there is

This is a normal part of drug development. The only difference is that they did it in a really expensive way so as to identify drugs specifically active on a particular part of the malarial life cycle. There are three more parts to drug development after this, and the vast majority (read: almost all) of these compounds will fail, leaving (if you're lucky) 1 compound that actually works. Then you've got to show it works in four stages in humans.

There's still over 600 compounds to study further. They made very early research results public, not a working drug. Going from 600+ unpatented candidates to an FDA approved treatment will require many years and likely hundreds of millions if not billions of dollars. The likelyhood this will result in a final "open source" compound seems extremely unlikely, unless I'm missing a big piece of this story.

Introverts can feel out of place within our Western culture that values extraversion. A new study found that introverts become unhappy with themselves if they compare themselves to an extraverted cultural ideal, but if they accept their authentic, quiet selves, they can flourish and be fulfilled.

Introverts can feel out of place within our Western culture that values extraversion. A new study...

Anyone interested in the subject of introversion should read Quiet: The Power of Introverts by Susan Cain. It's a great book and can explain a lot for both an extrovert or an introvert who feels unhappy about the extrovert status quo.

Anyway, big thing to take away is that extro-introversion happens on a spectrum, not every introvert is 100% on the introvert scale, likewise for extroverts. People don't seem to understand that introverts can be party animals or gregarious like any extrovert. What happens often is that people assume a lot about introverts, when they really have no idea.

To be fair, some people are more socially awkward than introverted, and even if they happen to also be introverts (extroverted socially awkward exist too but are less common IMO) their lack of social skills isolates them too much even with a lowered need for social contact.

Being isolated on a desert island for years will make you unwell, even if you are introverted.

Pardon me if I'm having a knee-jerk reaction here but the article doesn't seem to adequately explain what they consider as 'Eastern culture' that presumably values introversion.

Eastern culture as I've grown up with is all about social activities. You do everything together or else you're an antisocial weirdo. You stay back after work 'voluntarily' because your boss hasn't left yet. You go to drink with your boss and your colleagues until your face falls off, attending to their every whim and gesture.

This is not a kind society to introverts or people who find solitude to be a welcome company.

extroverted socially awkward exist too

These are the people who strike up random conversations with strangers and immediately start talking about personal or socially inappropriate things.

Narcissists are less likely to support democracy, finds a new study, which suggests this is probably because narcissists tend to feel entitled and superior to others, which results in lower tolerance of diverse political opinions.

An important note, the article says, "high narcissism coupled with low self-esteem" . Sounds like a dangerous combo

You hate yourself and think other people are even worse. You know how shit you are and yet you still manage to tower above the scum around you.

high narcissism and low self-esteem predict decreased support for democracy

​

I'm confused. I know that narcissism and low self-esteem are related, but I don't see how low self-esteem and feeling entitled and superior to others are related? I used to suffer from low self esteem for a decade, and I certainly did not feel superior to others. In fact, I felt vastly inferior.

Can anyone explain this?

​

The narcissist constructs a fake self that he presents to people and himself. That's why Narcissus is in love with his reflection, not with himself.

That constructed image is superior to everyone and deserving of admiration from everyone, hence the superiority feeling. But he is deeply aware that the image he is projecting is fake, even though he looses himself in it. That awareness is tied to his low self esteem.

Long story short : if the narcissist had any self esteem, he would not construct a fake image to show to the world.

"Children from high-income (top 1%) families are ten times as likely to become inventors as those from below-median income families. These gaps persist even among children with similar math test scores in early childhood."

"Children from high-income (top 1%) families are ten times as likely to become inventors as those...

Well, this just seems like a given. Living in a higher-income family usually means a better home life/less stress, more freedom to pursue your own interests, etc. It also means that you can afford materials, patent fees, screw ups, etc. that those from lower-income families can't.

Risk tolerance is much easier to maintain at a higher level when the risks you run don't actually include starvation and homelessness.

Or as the old adage goes, "it takes money to make money."

You also have access to the most valuable thing you can have- free advice from successful people. Lots of it. Tons of it, both as formal advice and informal learning. You can just absorb the attitudes and outlooks that make for a successful inventor instead of having to figure them out on your own.

No matter how many resources you hand to a kid during school hours, nothing can replace the ability to say "Hey, what about..." during dinner and get a quality answer.

Older people can come to believe their own lies

New research shows that within an hour of telling a falsehood, seniors may think it's the truth.

Paige said her findings suggest that telling a falsehood scrambles older people’s memory so they have a harder time recalling what really happened, in effect giving greater credence to the lie.

Highlights

• Lying requires cognitive control, which may impair memory at later test.

• Participants lied about completing actions while EEG data were collected.

• Older adults had reduced correct memory for items to which they lied.

• Frontal negativity emerged prior to response, greater for lie than truth responses.

• Results suggest neural activation is associated with working memory.

Abstract:

False memories are elicited from exposure to misleading information. It is possible that self-provided misinformation, or lying, has similar effects. We hypothesized that lying impairs memory for younger adults, as increased cognitive control, necessary to inhibit a truthful response, comes at the expense of retaining veridical information in memory. Because older adults show deficits in cognitive control, we hypothesized their memory is unaffected by lying. In the present study, participants made truthful and deceptive responses on a computer while EEG data were recorded. We investigated medial frontal negativity (MFN), an ERP component associated with deception and cognitive control, which may be differentially generated across age groups due to differences in cognitive control. Unexpectedly, results revealed that older adults showed reduced accurate memory for items to which they previously lied compared to younger adults. There were no age differences in correct memory for truth items. We did not find the expected MFN effect, however results revealed long-lasting negative slow waves (NSW) to lie items across age in the pre-response period and following the response cue, suggesting the role of working memory processes in deception. These findings demonstrate that lying is another source of misinformation and influences memory differently across the lifespan.

Because older adults show deficits in cognitive control...

On average.

This will be interpreted as proof that everyone over [speaker's age + 20] lies constantly and believes all their own lies.

Currently wondering if younger people showing symptoms of declining cognitive control could show similar results. Testing for cognitive control and determining a spectrum that may correlate to subjects abilities might be worth looking into for all ages.

Yes. This really should not become a stick against old people, but could provide explanation for why certain seniors with an established pattern of believing in BS do what they do.

The Amazon is worth $8.2 billion a year if it’s left standing, finds a new study in Nature. In many parts of the rainforest, that economic benefit far outweighs the short-term gain of tearing it down. “The forest should unambiguously be saved when measured in a purely economic sense”.

The cattle ranchers and soybeans farmers don't care, they want that short-term money in the now. And the new President-elect of Brazil doesn't give a hootin hollar either.

Yes, this is the problem. The value of the rainforest does not accrue to the bank accounts of the people who want to cut it down unless it's cut down.

Easy for us to say from here. These comments really show how disconnected people here are from the real world.

Ideally, nobody should be cutting amazon down because it is important to the world’s weather system.

But tell that to a starving farmer living near its edge making $2 a day. Tell him he cannot cut trees and sell timber because world’s temperature will rise by 2C in next 30 years. He is more worried about his next meal.

California cut 98% of it’s redwoods and made that sweet $$$, economic progress and railways. Why can’t people in Brazil do that? It hurts the world? Then pay up. Pay them for not using their resources. Make sure those farmers aren’t living in near starvation and need not cut down trees for their next meal

If correct, that’s not that much money. My employer’s annual budget is $2.5B.

A ton of people are taking notice, really

The title is incredibly misleading. There are tons of grassroots type attempts to do something about it. My next door neighbor has even started a hive in an attempt to help. A lot of people know the score it's just the corporate world only gives a shit about money and fuck everything else so it's incredibly difficult to reverse the damage.

Tons of people know, the corporations with enough power to do something about it simply don't care.

What is causing the insect collapse? I read an article yesterday suggesting a decline over the past few decades of 60% to 99.6% depending on species. This is happening all over the world.
