Caffeine increases problem solving abilities, but not creativity

A new study confirms that caffeine can improve the level of concentration and therefore also the level of problem solving, but it cannot stimulate creativity, a stereotype that has always been widespread but that no study has ever really eradicated.
Darya Zabelina, professor of psychology at the University of Arkansas and author of a new study that appeared in Consciousness and Cognition, tried it.

In fact, the stimulating effect of caffeine on creativity is a much lesser known characteristic of the main benefits that this substance, usually taken through coffee, can provide, such as greater vigilance, more attention or even greater physical performance.
The researcher carried out a study on 80 volunteers divided into two groups: those in the first group took a 200 mg caffeine pill (equivalent to a cup of coffee), those in the second group a placebo pill.

The participants and then performed standard tests on convergent or divergent thinking, working memory and mood.
The researcher realized that those who received the caffeine saw a significant improvement in the possibility of solving problems, thanks to the higher level of concentration and attention, but had no effect on creative thinking.

This means not only no positive effect but also no negative effect: this means that all those who need creativity, such as artists or writers, can still continue to drink coffee as it will certainly not make things worse.

Squatting improves health unlike sitting down

A team of researchers from the University of Southern California made an interesting discovery about the Hadza ethnicity of Tanzania, a population of a few hundred people who live hunting and gathering food near Lake Eyasi.
They found that members of this ethnic group seem not to present the main markers for heart and metabolic diseases, markers that are common in people of industrialized nations. The researchers soon came to a conclusion: members of this ethnic group used to squat or kneel very often, more often than they could sit.

The researchers carried out a study on some members of this population by making them wear devices to measure physical activity and rest periods. In addition to having good levels of physical activity, members of this ethnic group also show high levels of inactivity.
Members In fact, for 9-10 hours a day, children of this ethnic group are used to kneel or crouch, for example, around a fire. These are resting postures that still involve a minimum of muscular activity compared to sitting, which practically does not involve any.

And this conclusion leads to another one: squatting and kneeling can be considered as resting positions for human evolution and even favourable for health compared to sitting.
Indeed, various studies have highlighted the negative aspect of sitting for many hours a day, a position which has repeatedly shown that it can increase the risks of various diseases, including cardiovascular diseases. This is because the sitting position involves a very low if not no muscle activity and consequently a low level of metabolism continued for hours hours.

According to researchers at the American University, the rest positions used before the invention of the chairs were basically squatting and kneeling, two positions that involve higher levels of muscle activity than sitting.
Precisely because of this, these positions can help people protect themselves from the harmful effects of inactivity while not doing any exercise per se.

David Raichlen, professor of biological sciences and one of the authors of the study, thinks that human physiology itself has adapted to the conditions we wanted it to. This means that if inactivity and sitting down are harmful things, the evolutionary history of human beings has evidently not given much space to this type of inactivity, unlike what we do today, a time when sitting down has become the primary activity of the day for many people.

An Energy Efficient Home

In today’s world, saving energy–while increasing comfort–is driving innovation in the home industry market. The weather around the globe shows winters reaching dramatic lows, and summers seeing record highs. This is leading consumers to search more and more for the best ways to create an energy efficient home.

Do You Have an Energy Efficient Home?

Chances are, if you have to wonder, the answer is probably, “No.” Real estate experts understand that investing in your home’s energy-efficient, you gain value over the long term. By paying attention to whether or not you have purchased Energy Star products, you can really affect the performance of appliances, windows, lighting & more–finally creating an energy-efficient home.

What Causes Energy Loss?

The type of products you have in your home make quite a difference, based on quality and age of those choices. Some statistics show energy loss at the window to be up to 50%, depending on where you live. By replacing older non-efficient products when they need to be replaced, you can save quite a lot, even within the first year or two. This is especially true if the products in your home are older than ten years old. This is when you have to start deciding if the cost savings outweighs the cost of replacement.

How to Determine Quality

When replacing the products in your home, we’ve mentioned looking to Energy Star rated products. Another great way to determine high-quality products for an energy efficient home is to visit for awards and accolades given to brands that are going above and beyond for energy savings. A good example is the Hunter Douglas brand of window coverings, which received the first ever energy performance rating for window attachments. Furthermore, when looking at small businesses to work with when improving your home, looking for them to have specific expertise in the area of home improvement you’d like to see, like Skyline Window Coverings, based in Chicago, IL.
We are living in a time when saving energy is extremely important for reducing the carbon footprint, saving money and increasing comfort. Creating an energy-efficient home is one of the ways to achieve all three!

Mangroves are essential to protect coastlines from flooding and should be protected

The mangroves, with their intricate development, act as barriers and reduce annual flooding at the most critical points around the globe. Another new study underlines the positive aspects of this plant and its intrinsic and particular growth capacity in relation to savings, in terms of billions of dollars per year, which allow the reduction of flood risks.

The study, published in Scientific Reports, highlights how these plants are even more important today, and in the near future, due to the ongoing climate change that is actually increasing the risks of coastal flooding caused by rising sea levels and the increasing intensity of hurricanes.

Researchers have considered more than 700,000 km of coastline around the world by creating models and analysing flood risk and the benefits of this plant.
The results show that mangroves actually reduce flooding and that more economic incentives would be needed to protect these plants.

“Now that we can assess these flood protection benefits, all kinds of new opportunities are opening up to finance mangrove conservation and restoration with savings for insurance premiums, storm reconstruction, climate adaptation and community development,” says Michael Beck, professor at the Institute of Marine Sciences at the University of California at Santa Cruz, one of the authors of the study with Pelayo Menéndez, his colleague at the same institute.

The mangrove tree is a plant that is widespread basically all over the world, but many of them have been destroyed or have died for activities such as aquaculture and coastal development in general, a development that often sees the construction of infrastructures right near the areas where these plants are born and grow.

Just think of the case of Florida: since the beginning of the last century the intense development near the coasts of this American state has caused a contingent loss of real mangrove forests. This loss has resulted in more floods and floods.

The most positive characteristic of these plants is that they are resistant and can grow like weeds, even in the middle of the city, if given “half a chance”, as Beck himself explains.

New membrane produces 100 times more energy from seawater

A new membrane which, according to the press release presenting the study published in Nature Nanotechnology, “can produce one hundred times more energy from sea water”, was created by a group of chemists from the University of Leiden. The new membrane is ultra-thin and only one molecule thick.

It is a membrane that, once introduced into the water, can absorb the energy coming from the particles moving from one side to the other, which happens very easily when salt water comes into contact with fresh water because there is an exchange of salt. This is the same process that is usually used to desalinate sea water.

The new membrane developed by the chemists in Leiden, however, is much more efficient because it produces 100 times more energy than “classic” membranes.

The membrane is made of carbon and is porous and thin at the same time, unlike the more common membranes which are either porous or thin.

The membrane was created by spreading oily molecules on the surface of the water. It then formed a film which, once heated, saw the creation of a stable porous membrane.
“The membrane we created is only two nanometres thick and is permeable to potassium ions. We can modify the properties of the membrane using a different molecular block. In this way we can adapt it to meet any requirement,” says Xue Liu, one of the authors of the study and the creators of the membrane together with his colleague Grégory Schneider.

The new membrane is similar to graphene but at the same time different from this material, as Schneider himself explains: “When making a membrane, many researchers start with graphene, which is very thin but not porous. Then they try to drill holes to make it more permeable. We did the opposite by assembling small molecules and building a larger porous membrane from those molecules. Compared to graphene, it contains imperfections, but that’s what gives it its special properties.
