We're living longer than ever, but that means we now have to think about new issues that were uncommon when life expectancy was low.
Muscles shrink and their strength dwindles as we age. When that is excessive, the condition is called sarcopenia, and it affects every third person over the age of 80, reducing mobility, autonomy and quality of life.
There may be hope in the form of a well-known drug, Rapamycin, that can delay the progression of age-related muscle weakness.
Are Proud Boys and Antifa fighting each other 'to oppose fascism' a product of the COVID-19 pandemic? No, militant groups have always attracted people with pathologies who just need a reason to be violent, but pandemics do cause social unrest, at least historically.
There is a lot more isolation than in past pandemics but also a lot more community around SARS-CoV-2, the 2019 form of the coronavirus that has locked up most developed countries. Unlike the past, where nature was just trying to kill us, and the randomness of it all caused panic, people know where it originated and how. We know how to mitigate it. We are equipped to try and help those with co-morbidities. A lot of people have died, no one downplays that, but a lot fewer than in any pandemic ever.
There’s a thin line between working hard enough and working too hard. Pushing your body to reach new levels of fitness requires commitment, effort and a willingness to put yourself through intense, challenging workouts on a regular basis.
But more isn’t always better. Without the right balance of rest and recovery you could end up spiralling into a long-term fatigue condition called overtraining syndrome. The condition results in long-term reduced physical performance, and may be accompanied by other physiological and psychological symptoms (such as low mood or poor sleep) – though this isn’t always the case. It can take weeks, months and even years to recover from this condition.
Did you read a paper saying we can prevent ocean damage under climate change scenarios by dumping iron into water to spur phytoplankton growth? Germans did, and were so convinced they began doing illegal live experiments
The model used a best-case scenario, which any entry-level chess player knows is a bad idea - they forgot to falsify their own hypothesis in their zeal to do something

notes that many ambitious climate action plans rely on climate engineering technologies where the risks are unknown. They are more like TED talks than real plans.
A brain-controlled prosthetic limb have shown that machine learning techniques helped an individual with paralysis learn to control motion using their brain activity without requiring extensive daily retraining.
It is proof-of-concept for how future models can overcome limitations of prior brain-computer interface efforts, which existing had to be reset and recalibrated each day, almost like asking someone to learn to ride a bike over and over again each day.
Children learn languages much easier than adults, and also seem to recover from neural injuries better. The reason may be that adults process most discrete neural tasks in specific areas in one or the other of their brain's two hemispheres, while kids use both the right and left hemispheres to do the same task.
If you are a tourist and visit California in the United States or Bavaria in Germany, you will quickly notice it is not like a lot of other places in those countries. A cultural mentality exists and people who identify with the stereotype are more likely to stay or even move there.A new paper
finds that people who live in mountain regions of the U.S. maintain more of that sensibility even in the modern era. Historian Frederick Jackson Turner, a Harvard academic, presented his thesis on the US frontier in 1893, describing the "coarseness and strength combined with acuteness and acquisitiveness" it had forged in the American character.
You can't market a "Tennessee whiskey" unless it goes through charcoal filtration called the Lincoln County Process, named such after the locale of the original Jack Daniel's distillery.
Charcoal is not exclusive to American blended whiskey, this type of filtration is a common step in the production of distilled beverages, including vodka and rum, but while "charcoal mellowing" in Tennesse Whiskey varies from manufacturer to manufacturer, they all involve passing the fresh whiskey distillate through a bed of charcoal, usually derived from burnt sugar maple, prior to barrel-aging the product.
The reopening of cafes has been one of the highlights of relaxed COVID-19 restrictions for many Australians. During lockdowns, long queues for takeaway coffee were testimony to caffeine’s relevance to our lives.
As every other aspect of human life, science communication has suffered a significant setback due to the ongoing Covid-19-induced pandemic. While regular meetings of scientific teams can be effectively held online, through zoom or skype, it is the big conferences that are suffering the biggest blow. And this is not good, for several reasons.
