The very small is very weird; I explained that the last time in Small Is Ugly 1 already with help of the example of water being in the driest of places (Vastness and Fastness of the Small helps Evolution is of course somewhat related). And today, I still do not mean supposed "quantum weirdness", which is not about small stuff.-->
There's a common trope in Hollywood celebrities who gain weight and receive attention for it. They talk about how much healthier and better they feel about themselves at higher weight - and then they immediately lose weight and talk about how much healthier and better they feel about themselves.
Severely obese people who aren't famous also experience much better spirits once they shed weight through diet, lifestyle changes or medical intervention but Valentina Ivezaj and Carlos Grilo of the Yale University School of Medicine write in Obesity Surgery that it is not a psychological magic bullet.
Antidepressants are the most commonly used treatment for social anxiety disorder but we know they don't work for many people and their efficacy goes down over time.
New research finds they are not even needed in many instances.
Social anxiety disorder is a condition characterized by fear and avoidance of social situations. It affects as many as 13 percent of the Western world. For most people, it is not severe, and they never receive treatment for the disorder but those who do get treatment are usually assigned medication.
The appeal of artificial photosynthesis, in which the electrochemical reduction of carbon dioxide is used to produce clean, green and sustainable fuels, is that we can turn an atmospheric byproduct into a renewable energy technology.
However, finding a catalyst for reducing carbon dioxide that is highly selective and efficient has proven to be a huge scientific challenge.
Peidong Yang, a chemist with Berkeley Lab's Materials Sciences Division, led a study in which bimetallic nanoparticles of gold and copper were used as the catalyst for the carbon dioxide reduction. The results experimentally revealed for the first time the critical influence of the electronic and geometric effects in the reduction reaction.

A new discovery of thousands of Stone Age tools has provided a major rethink about human innovation 325,000 years ago - and how early technological developments spread across the world.
The researchers found evidence which challenges the belief that a type of technology known as Levallois – where the flakes and blades of stones were used to make useful products such as hunting weapons – was invented in Africa and then spread to other continents as the human population expanded.
They discovered at an archaeological site in Armenia that these types of tools already existed there between 325,000 and 335,000 years ago, suggesting that local populations developed them out of a more basic type of technology, known as biface, which was also found at the site.
Many of the choices we make are informed by experiences we've had in the past but we know that sometimes it is better to throw all that out and take a risk on something new.
Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have shown that the brain can temporarily disconnect information about past experience from decision-making circuits, thereby triggering random behavior.
The diagram of the circuit resembles the letter “H” where the motor is the cross-bar and four switches form the legs.
Mother Nature may be out to kill us but we shouldn't take it personally. She is out to kill everything. We just never noticed in the past.
Today, thanks to long-term science projects, we can see how nature pits species off against each other. And biologists are studying streams to optimize how to prevent tallgrass prairies from turning into shrublands and forests.
People who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience, find biomedical engineers at the University of Minnesota writing in TECHNOLOGY.
The nice thing about telescopes is that we can look back in time - light that is reaching us now may have originated a few hundred million years after the Big Bang, which means astronomers can view the universe as it was when it was much younger.
But sometimes we can be fooled by entire galaxies. DDO 68, otherwise known as UGC 5340, a ragged collection of stars and gas clouds, at first was thought to be a recently-formed galaxy in our own cosmic neighborhood.

For some people, their own standard is much more demanding that anything the outside world could expect. Perfectionism is a bigger risk factor in suicide than it is credited for, says York University Psychology Professor Gordon Flett, who is calling for closer attention to its potential destructiveness, adding that clinical guidelines should include perfectionism as a separate factor for suicide risk assessment and intervention.
A new evolutionary psychology paper says that men and women have different age preferences regarding sexual partners - but it's primarily women realize their preferences.
The human papillomavirus (HPV) vaccine has been controversial in both the United States and European countries like Germany. It prevents about 70% of cervical cancers, cervical cancer is uncommon and highly treatable, and it will need another vaccine before girls who are given it even become adults. Along with those data issues, academic scientists and the public have been engaged in a culture war against pharmaceutical companies - that vaccines are exempt from ordinary lawsuits and that the vaccine was marketed heavily just after an expensive settlement by manufacturer Merck was not lost on the public.
