WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING
THIS IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS
“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”
"Being a scientist is a state of mind, not a profession!"
"Science, when it's done right, can yield amazing things".
The Reach of Scientific Research From Labs to Laymen
The aim of science is not only to open a door to infinite knowledge and wisdom but to set a limit to infinite error.
"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.
Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.
If you are scientifically literate the world looks very different to you.
We do science and science communication not because they are easy but because they are difficult!
“Science is not a subject you studied in school. It’s life. We 're brought into existence by it!"

While some factors that favor scratching—such as the cat's personality or the presence of children—cannot be changed, others can, the researchers said. Placing scratch posts in areas the cat frequently passes or near to their preferred resting spot, or the use of pheromones, for example, can lessen cats' scratching on furniture.
Providing safe hiding places, elevated observation spots, and ample play opportunities can also help alleviate stress and engage the cat in more constructive activities.
The key is to establish multiple short play sessions that mimic successful hunting scenarios. These play sessions are more likely to sustain cats' interest and reduce stress, which ultimately can reduce excessive scratching on furniture. They can also foster the bond between cats and their caretakers, the researchers say.
Understanding the underlying emotional motivations of scratching behavior, such as frustration, which seem to be linked to personality traits and environmental factors, allows caregivers to address these issues directly.
Evaluating Undesired Scratching in Domestic Cats: A Multifactorial Approach to Understand Risk Factors, Frontiers in Veterinary Science (2024). DOI: 10.3389/fvets.2024.1403068

Many cat owners are familiar with torn cushions, carpets, and couches. The feline instinct to scratch is innate, but is often perceived as a behavioral problem by cat owners, and sometimes leads to interventions that are not cat-friendly.
Now, an international team of researchers has investigated which factors influence undesired scratching behavior in domestic cats. The team has published its findings in Frontiers in Veterinary Science.
Scientists found that certain factors—such as the presence of children at home, personality traits of cats, and their activity levels—significantly impact the extent of scratching behaviour.
The researchers' results showed that there are several factors that influence cats' scratching behaviour. They saw a clear link between certain environmental and behavioural factors and increased scratching behaviour in cats.
Specifically, the presence of children in the home as well as high levels of play and nocturnal activity significantly contribute to increased scratching. Cats described as aggressive or disruptive also exhibited higher levels of scratching.
Stress, the researchers said, was found to be a leading reason for unwanted scratching. For example, the presence of children, particularly while they are small, might amplify stress and be one of several causes that can make felines stress-scratch. The link between increased scratching and children in the home, however, is not fully understood and further study is needed. Another factor that could also be connected to stress is playfulness. When cats play for a long time, their stress levels can rise because of the uninterrupted stimulation.

In the past, some other observational studies have also linked artificial light at night to insulin resistance, but these experiments did not measure indoor, artificial light sources nearly as closely or for as long.
Emerging evidence in animals and humans suggests exposure to artificial light can disrupt circadian rhythms, leading to reduced glucose tolerance, altered insulin secretion, and weight gain – all of which are tied to an increased risk of metabolic disorders like type 2 diabetes.
One major limitation of the study is that researchers were not able to take into account meal times, which can have an impact on both circadian rhythms and glucose tolerance. Furthermore, some socioeconomic factors, like a person's housing situation, were accounted for at a regional, not an individual level, and only older adults were considered.
There's also the fact that individual bodies respond very differently to light, with some studies suggesting the intensity of light needed to suppress the production of melatonin, which helps regulate our circadian rhythm, can range from 6 to 350 lux.
Nevertheless, previous experiments suggest that when melatonin is disrupted and the circadian rhythm is thrown out of whack, it can lead to the pancreas secreting less insulin. This could be a contributing factor to the development of diabetes.
Far more rigorous studies are needed before scientists can truly understand how light at night impacts the circadian rhythm and what that may do, in turn, to the health of the body's metabolism.
Some studies suggest that even a weekend of camping without artificial light can help reset a person's circadian rhythm. Perhaps that's just what the doctor should order.

Cyclone Freddy, which crossed the entire southern Indian Ocean before wreaking devastation on southeastern Africa last year, was the longest-lasting tropical cyclone ever recorded at 36 days, the UN confirmed Tuesday.
A panel of experts has been poring over the data surrounding the storm since its remarkable journey in February and March last year.
The United Nations' weather and climate agency concluded it had indeed broken the previous record.
The extreme weather evaluation committee "recognised Tropical Cyclone Freddy's duration of 36.0 days at tropical storm status or higher as the new world record for the longest tropical cyclone duration", the World Meteorological Organization (WMO) said in a statement.

In tibia injuries, the flow of the hemolymph was less impeded, meaning bacteria could enter the body faster. While in femur injuries the speed of the blood circulation in the leg was slowed down.
You may expect, then, if tibia damage results in faster infections, amputating the full leg would be most appropriate, but the opposite is observed. It turns out the speed at which the ants can amputate a leg makes a difference.
An ant-assisted amputation takes at least 40 minutes to complete. Experimental testing demonstrated that with tibia injuries, if the leg was not immediately removed post-infection, the ant would not survive.
"Thus, because they are unable to cut the leg sufficiently quickly to prevent the spread of harmful bacteria, ants try to limit the probability of lethal infection by spending more time cleaning the tibia wound.
The fact that the ants are able to diagnose a wound, see if it's infected or sterile, and treat it accordingly over long periods of time by other individuals—the only medical system that can rival that would be the human one.
And they can do it without studying medicine and learning surgery! It's really all innate behaviour!
Ant behaviors change based on the age of an individual, but there is very little evidence of any learning.
"When you look at the videos where you have the ant presenting the injured leg and letting the other one bite off completely voluntarily, and then present the newly made wound so another one can finish cleaning process—this level of innate cooperation is quite striking", say the researchers.
Erik Frank et al, Wound-dependent leg amputations to combat infections in an ant society, Current Biology (2024). DOI: 10.1016/j.cub.2024.06.021. www.cell.com/current-biology/f … 0960-9822(24)00805-4

Saving lives through surgery is no longer exclusive to humans. In a study published July 2 in the journal Current Biology, scientists detail how Florida carpenter ants, a common, brown species native to its namesake, selectively treat the wounded limbs of fellow nestmates—either by wound cleaning or amputation.
When experimentally testing the effectiveness of these "treatments," not only did they aid in recovery, but the research team found the ants' choice of care catered to the type of injury presented to them.
The researchers found that this mechanical care involves one of two routes. The ants would either perform wound cleaning with just their mouthparts or perform a cleaning followed by the full amputation of the leg. To select which route they take, the ants appear to assess the type of injury to make informed adjustments on how best to treat.
In this study, two types of leg injuries were analyzed, lacerations on the femur and those on the ankle-like tibia. All femur injuries were accompanied by initial cleaning of the cut by a nestmate, followed by a nestmate chewing off the leg entirely. In contrast, tibia injuries only received the mouth cleaning. In both cases, intervention resulted in ants with experimentally infected wounds having a much greater survival rate.
Femur injuries, where they always amputated the leg, had a success rate around 90% or 95%. And for the tibia, where they did not amputate, it still achieved about the survival rate of 75%.

A common infection-causing bacteria was much less likely to evolve antibiotic resistance when treated with a mixture of antimicrobial peptides rather than a single peptide, making these mixtures a viable strategy for developing new antibiotic treatments. Researchers report these findings in a study published July 2 in PLOS Biology.
Antibiotic-resistant bacteria have become a major threat to public health. The World Health Organization estimates that 1.27 million people died directly from drug-resistant strains in 2019 and these strains contributed to 4.95 million deaths.
While bacteria naturally evolve resistance to antibiotics, misuse and overuse of these drugs has accelerated the problem, rendering many antibiotics ineffective. One emerging strategy to combat antibiotic resistance is the use of antimicrobial peptides, which are chains of amino acids that function as broad-spectrum antimicrobial compounds and are key components of the innate immune system in animals, fungi and plants.
In the new study, researchers investigated whether antimicrobial peptide mixtures synthesized in the lab could reduce the risk of the pathogen Pseudomonas aeruginosa from evolving antimicrobial resistance, compared to exposure to a single antimicrobial peptide.
They found that using antimicrobial peptide mixtures carried a much lower risk of the bacteria developing resistance. The mixtures also helped prevent the bacteria from developing cross-resistance to other antimicrobial drugs, while maintaining—or even improving—drug sensitivity.
Overall, the findings suggest that the use of antimicrobial peptide mixtures is a strategy worth pursuing in the search for new, longer-lasting treatments for bacteria.
The researchers suspect that using a cocktail of multiple antimicrobial peptides creates a larger set of challenges for bacteria to overcome, which can potentially delay the evolution of resistance, compared to traditional antibiotics. Furthermore, these cocktails can be synthesized affordably, and previous studies have shown them to be non-toxic in mice.

Due to this connection, the team set out to test if exercise could influence thermal age. They asked 23 participants to jump rope for at least 800 times daily for two weeks. To the team's surprise, these participants reduced their thermal age by five years after just two weeks of exercise.
Next, the team wants to explore if they can use thermal facial imaging to predict other diseases, such as sleeping disorders or cardiovascular problems.
Applying thermal facial imaging in clinical settings holds significant potential for early disease diagnosis and intervention.
Yu et al. Thermal Face Image Analyses Reveal Quantitative Hallmarks of Aging and Metabolic Diseases, Cell Metabolism (2024). DOI: 10.1016/j.cmet.2024.05.012. www.cell.com/cell-metabolism/f … 1550-4131(24)00188-8
A colder nose and warmer cheeks may be a telltale sign of rising blood pressure. Researchers discovered that temperatures in different face regions are associated with various chronic illnesses, such as diabetes and high blood pressure. These temperature differences are not easily perceptible by one's own touch but can instead be identified using specific AI-derived spatial temperature patterns that require a thermal camera and a data-trained model.
The results appeared July 2 in the journal Cell Metabolism. With further research, doctors could one day use this simple and non-invasive approach for early detection of diseases.
The researchers had previously used 3Dfacial structure to predict people's biological age, which indicates how well the body is aging. Biological age is closely related to the risk of diseases, including cancer and diabetes. They were curious if other features of the face, such as temperature, could also predict aging rate and health status.
They
analyzed facial temperatures of more than 2,800 Chinese participants between the ages of 21 and 88. Then, the researchers used the information to train AI models that could predict a person's thermal age. They identified several key facial regions where the temperatures were significantly related to age and health, including the nose, eyes and cheeks.
The research team found the temperature of the nose decreases with age at a rate faster than other parts of the face, meaning people with warmer noses have a younger thermal age. At the same time, temperatures around the eyes tend to increase with age.
The team also found that people with metabolic disorders such as diabetes and fatty liver disease had faster thermal aging. They tended to have higher eye area temperatures than their healthy counterparts of the same age. People with elevated blood pressure also had higher cheek temperatures.
