Physicists have discovered the technology that allows them to produce the perfect coffee with up to 10% less beans.

Climate change is making coffee production more difficult, and it is becoming more important to brew it in the most efficient way possible. Arnold Mattissen At the University of Pennsylvania.

“Coffee is becoming more difficult to grow, so that’s why coffee prices could increase over the next few years,” he says. “The idea for this study was to actually see if we could do anything by reducing the amount of coffee beans needed while maintaining the same amount of brewing.

Mathijssen and his colleagues focused on pouring coffee, slowly adding hot water to the corn-shaped paper filter site. Their advice can be summarized into some very simple tips. First, pour slowly. The longer the beans are soaked in the water inside the corn, the more extraction will occur.

But this works to some extent. If poured slowly, the lot is not fully confused. They settle at the bottom and start to actually reduce the amount of extraction. To combat this, the second hint is to pour from the height.

“Living up the kettle height gives you more energy essentially from gravity,” says Matigen. “Afterwards, all particles enter this kind of global circulation that is not normally obtained when poured from a lower height.”

Team experiments showed that raising the kettle to 50 centimeters of cone increased the strength of the coffee. However, Mathijssen warns that if poured too high, the water flow will begin to collapse, forming unconnected Glugs, causing the coffee corn circulation to be confused again. Needless to say, boiling water from too high can pose a risk of burns.

“Be rational,” says Mattigen. “First, try slowly. Then lift it up. [the kettle] Go as slowly as possible, but please don’t let it [the flow of water] “We’re goodbye,” he says. “That’s the strategy I follow.”

While this process is highly dependent on the type of coffee, the size of the site, the type of kettle used, and many other factors, researchers have found that the technique can lead to a 5% to 10% savings in the amount of coffee needed. Their experiments showed that the resulting brew had the same amount of dissolved solids, so it should be just as strong and flavorful.

Kennedy commends the school ban on mobile phones for scientifically supported reasons

Health and Human Services Secretary Robert F. Kennedy Jr. focused on school mobile phones as part of his “American Health Again Again” agenda this week.

In an interview with “Fox & Friends” on Thursday, Kennedy praised the restrictions on mobile phones in schools, citing health risks associated with phone use among children and teenagers supported by scientific research.

Kennedy pointed out the link between social media use and depression and poor school performance, as well as the potential neurological damage caused by electromagnetic radiation emitted by cell phones that could lead to cancer.

Studies have shown that excessive social media use on smartphones negatively impacts teens’ mental health, increasing the risk of depression and anxiety while the use of cell phones in schools can lead to poor academic performance, including lower grades.

Despite most studies finding no direct link between cell phone use and cancer or DNA damage, Kennedy’s statements have mixed misinformation with scientific facts. The issue of limiting school cell phone use has bipartisan support, with nine states already implementing restrictions and 15 states and Washington, DC considering legislation to do the same.

While concerns about the health effects of cell phone radiation exist, there is currently insufficient scientific evidence to definitively link cell phone use to cancer. Kennedy’s claims about the physical harms of cell phones have been met with skepticism from many experts.

Despite the pros of mobile phones, such as being able to call 911 in emergencies, concerns about mental health risks and distractions in classrooms have led to debates over appropriate school policies regarding cell phone use.

Kennedy’s support for limiting school cell phone use aligns with efforts in some states to create a healthier learning environment by reducing phone distractions among students.

Before his role as HHS secretary, Kennedy emphasized the importance of parents and teachers making their own decisions regarding communication strategies without government interference.

Scientifically Determining Which Child Is Most Likely to Be the Favorite of Their Parents

Have you ever glanced around the dinner table and pondered about your parents’ favorite among your siblings? If you’re the youngest, you might want to look away.

A recent meta-analysis published in the Psychology Bulletin reveals that eldest daughters tend to receive preferential treatment from their parents.

Researchers examined 30 peer-reviewed journal articles and 14 databases, involving 19,469 participants, to explore how birth order, gender, temperament, and personality traits impact parental favoritism. The study showed that both mothers and fathers more often favored their daughters as compared to sons.

In terms of birth order, older siblings tended to receive more autonomy, which was viewed as preferential treatment. This favoritism was also evident in the amount of money spent on children and the level of control exerted by parents.

Children who exhibited responsible and organized traits were also more likely to be favored by their parents, indicating that parents may find them easier to manage and respond positively to.

“Parental differential treatment can have long-lasting effects on children,” stated lead author Dr. Alexander Jensen, an Associate Professor at Brigham Young University, USA.

“This study sheds light on which children are more susceptible to the impacts of favoritism, whether positive or negative.”

Jensen and his team also discovered that siblings receiving less favorable treatment often had poorer mental health and strained family relationships.

“It’s worth noting that this study is correlational and doesn’t explain why parents favor certain children,” Jensen added. “However, it does highlight areas where parents may need to be more mindful of their interactions with their children.”

Throughout human history, stories about fantastical beasts and supernatural beings have captivated our imagination. From werewolves and vampires to yetis and deep-sea monsters, mythical creatures have inspired countless folk tales and cultural works, as well as elaborate hoaxes.

Many intrepid explorers ventured into the wilderness in search of conclusive evidence of these beings’ existence. While some mythical creatures turned out to be real species, others remain purely fictional, and some are still the subject of intense debate.

Cryptids, creatures that have not yet been scientifically described, are the focus of cryptozoology, the study of these mysterious animals. But what is the real science behind these mythical creatures?

Legends of vampires have been portrayed in various forms of media, but scientists suggest that this myth may have originated from real medical conditions such as porphyria or tuberculosis.

Some believe that vampire legends arose from societal fears of death and decay, rather than actual creatures that feed on blood like vampire bats or leeches.

yeti

Centuries-old tales of the yeti, a giant two-legged hairy creature in the Himalayas, have fascinated explorers and cryptozoologists worldwide. However, modern DNA analysis has debunked the existence of the yeti, attributing sightings to bears.

Legends of giant sea snakes have historical roots, possibly inspired by sightings of the oarfish. Reports of oarfish rising to the surface in response to seismic activity could explain the myth of sea serpents as harbingers of doom.

griffin

Legends of the griffin, a winged creature with the body of a lion and the head of an eagle, may have originated from the discovery of early dinosaur fossils like the protoceratops. The griffin myth could have arisen from misinterpreted remains found in the Gobi Desert.

Scandinavian folklore of the Kraken, a giant octopus-like sea creature, has been linked to sightings of giant squids. While these deep-sea creatures are formidable, they are unlikely to attack large ships as depicted in the myths.

mermaid

Stories of mermaids, aquatic creatures with human bodies and fish-like tails, have ancient origins. These myths may have been inspired by sightings of manatees or dugongs by European sailors, combined with hallucinations from scurvy.

minotaur

The Greek myth of the Minotaur, a creature with the head of a bull and the body of a human, may have been influenced by seismic activity on the island of Crete, where earthquakes were common due to tectonic plate movements.

unicorn

The unicorn, a famous mythical creature depicted as a white horse with a horn, may have originated from mistranslated ancient texts referring to the aurochs. The legend of the unicorn persisted through the Middle Ages, fueled by the sale of narwhal tusks as unicorn horns.

5 Famous Monster Hoaxes

1. In 1958, giant footprints believed to be from Bigfoot were revealed to be a prank by Ray Wallace.

2. The “mermaids of Fiji” mummy was discovered to be a fake created by Japanese fishermen.

3. The Loch Ness Monster photo from 1934 was exposed as a hoax using a plastic head fixed to a toy submarine.

4. The “Cardiff Giant” petrified man was a sculpture created by George Hull.

5. The Cottingley Fairies photos were revealed to be cutouts from children’s books.

The simplest, scientifically supported method to determine if you are drinking adequate water

In the UK, the NHS recommends 6 to 8 cupsThe Harvard Medical School recommends drinking 1.2 liters of fluid per day, and points out that you should also get some fluid from the food you eat. 4-6 cups per dayBut it's the more extreme advice – drinking two litres of water a day – that has taken off online.

In 2016, the idea that getting most of your hydration from water is beneficial was debunked by Dr Stuart Galloway, an associate professor of physiology, kinesiology, and nutrition at the University of Stirling. His research showed that a range of drinks, including diuretic drinks such as lager and instant coffee, It did not promote additional fluid loss compared to drinking normal amounts of water..

But because everyone has a different body type, diet, and activity level, and different environments (hot, dry, humid, etc.), it's impossible to really say how much everyone needs to drink. Most people can tell if they need more water by feeling thirsty, but this desire weakens as we age. If in doubt, for the majority of adults, the number of times you go to the bathroom can be a useful indicator of adequate hydration, says Galloway.

“It takes into account differences in fluid loss due to environment and activity level, as well as changes in fluid intake. A good rule of thumb is that if your fluid intake is adequate, you'll be going to the bathroom four to six times in a typical day.”

If you're peeing more than six times, you're overdoing it, if you're peeing less than four times, you probably need to drink more water.

“This method has some drawbacks, including influences such as changes in kidney function with age, certain medications, or ingredients in different drinks that can affect urine concentration and volume,” he warns. “So this is a rough rule of thumb rather than a precise guide.”

Urine color can also be helpful, he says, with a similar caveat: “For best results, don't rely on a single marker, but evaluate them in combination.”

Scientifically Proven: The Best Method for Cutting a Sandwich

Posted on by
Reply

Many people believe that cutting a sandwich diagonally to create two triangles is the best way, but there isn’t solid scientific evidence to support this theory.

One explanation is that the triangular shape allows for the first two bites to be taken from a 45-degree corner, which has crust on only one side, giving quicker access to the center of the sandwich where the filling is most concentrated.

After biting into the corner, it’s recommended to eat 1-3 bites diagonally. This part will have no crust, and depending on the sandwich size, you may end up with an additional small triangle.

While each triangle eventually becomes a single 90-degree crust piece, cutting a sandwich into rectangles would result in two crust corners on each half instead of one.

Another reason for cutting sandwiches into triangles is that they are easier to eat: only kids and cartoon characters tend to take their first bite from the middle, resulting in a messy eating experience.

Beginning at one of the corners allows for a cleaner eating experience, and the 45-degree angle of the triangle maximizes the depth of each bite.

For those who want to extend this concept further, the sandwich can be cut into four triangles and eaten in three separate sessions.

This strategy is commonly used at children’s parties, although children often do not eat the 45-degree corner first. In such cases, cutting off the crust altogether may be a better option.

This article is a response to the question “What is the best way to cut a sandwich, scientifically speaking?” (asked by Jeremy Fry of Felixstowe).

8 Scientifically Proven Reasons Why Cats Are So Adorable

Posted on by
Reply

The study of cats is our favorite field of study (second only to information about dogs). We have compiled our favorite cat facts, from whether your cat truly loves you to how they use their whiskers. Enjoy these 8 fascinating cat facts confirmed by science.

1. Blinking slowly can help you befriend cats

Research has shown that squinting is the most effective way to build trust with a cat.

A study conducted by the Universities of Portsmouth and Sussex revealed that this technique mimics the “slow blink,” also known as a cat smile, and helps establish a bond between humans and cats.

According to Professor Karen McComb from the Department of Psychology at the University of Sussex, who oversaw the study, “As someone who studies animal behavior and has a cat, I’m pleased to be able to show that cats and humans can communicate in this way.”

After a cat has blinked slowly at its owner, the cat is more likely to reciprocate the slow blink than if there is no contact at all.

2. One in 10 pet cats suffers from separation anxiety

More than 1 in 10 pet cats surveyed in a study exhibited behavioral issues when temporarily separated from their owners.

Scientists observed that cats with separation-related problems tended to be from households without females or where multiple females lived. Lack of access to toys and absence of other pets in the home were also associated with similar behavioral issues in cats.

The analysis found that a significant percentage of sampled cats displayed behaviors associated with separation-related issues, including destructive behavior, excessive vocalization, and aggression.

3. Your cat really loves you

While food may have initially brought humans and cats together, cats have shown deep affection towards their human companions over time.

Recent studies indicate that cats exhibit behaviors similar to “secure attachment” seen in dogs, suggesting a strong bond between cats and their owners.

Cats exhibit behaviors beyond seeking food, indicating a deeper bond with their owners.

4. Cats can tell when a thunderstorm is approaching

Cats, along with other animals, have heightened senses that allow them to detect impending storms before their owners.

Your cat may sense changes in air pressure, smell rain, or hear distant thunder, alerting them to an oncoming storm.

5. Cats love boxes for their comfort

Cats seek out cozy hiding spots, such as boxes, for security and comfort, especially when sleeping.

Cats prefer warm environments and will utilize boxes for warmth and a sense of security.

6. Domestic cats impact local wildlife

Studies have shown that domestic cats contribute significantly to the decline of local wildlife populations.

Domestic cats have a concentrated impact on local prey due to their small home ranges, causing significant harm to bird and small mammal populations.

7. Cats cannot thrive on a vegan diet

Cats are obligate carnivores and require specific nutrients found only in meat sources, making a vegan diet unsuitable for cats.

Feeding cats a vegan diet can lead to severe health issues, such as blindness and heart failure, due to the lack of essential amino acids like taurine.

8. Cat whiskers are essential for hunting

Cat whiskers play a crucial role in hunting, providing sensory information to help cats navigate and hunt effectively.
