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!"

Ways you can help limit your pain during the insertion:
Time your IUD insertion procedure to around your period. The cervix is more open when you're on your period, so there's less sensitivity to pain. If the timing does not work out, it is still possible to have an IUD placed at any time in the cycle.
Medications. Take 600–800 mg of ibuprofen before your appointment. Ibuprofen is often recommended because it's a non-steroidal, anti-inflammatory drug that works specifically well on uterine tissue. Other options to ask your doctor about include a lidocaine numbing ointment or a lidocaine injection for the cervix, which can also decrease some of the pain. There are several networks of nerves supplying the uterus and cervix, which makes it difficult to completely numb the entire area with local anesthetics and eliminate all pain during an IUD insertion. But studies have shown that it may help with some of the pain during insertion. And depending on your situation, your doctor might also suggest an anti-anxiety medication before your insertion appointment.
Heat packs. Ask your doctor if a heat pack is available. Place this over your pelvis during the procedure to help ease the pain.
Other tips to prepare for the insertion procedure include:
Eating a meal before you come in.
Making sure you are hydrated.
Wearing comfy clothes.
Bringing a light snack for after the procedure.
Bringing a book or your phone to watch videos or listen to music. "This can take your mind off the process," Kuhn says.
Bringing or ask your doctor for pads for potential spotting afterwards.
Clearing your schedule for the day. The most painful part is during the 30 seconds when the IUD is being placed. But you may have some mild period-like cramping afterward and want to just be on the couch with a heating pack.

Bleeding, intense cramping, even fainting: These are some of the experiences women are sharing across social media about IUDs—especially with the pain they feel during an insertion.
IUDs—short for intrauterine devices—have become an increasingly popular birth control option. But along with the growing use of the small T-shaped devices, there are increasing concerns from women about whether health care professionals are fully addressing patients'pain.
This prompted the Centers for Disease Control and Prevention to update its guidelines regarding IUDs, advising doctors to tell patients about the possible pain and discuss pain relief options before putting in an IUD.
It depends, because everyone's pain tolerance is a bit different.
It's hard to know who's going to have more or less pain when having an IUD inserted.
There are three parts to the procedure that can typically cause pain. They include:
But experts say the pain shouldn't stop you from considering an IUD.
Hormonal IUDs have a variety of benefits such as shorter menstrual periods, lighter cramping, and not having to worry about an unintended pregnancy. They can also be used to treat endometriosis, anemia, and even prevent endometrial pre-cancer and cancer.
IUDs are as effective as getting your tubes tied in terms of prevention of pregnancy. They're really an investment that can last for up to eight to 10 years. And working with your doctor ahead of time can help make the experience more comfortable for you.

Researchers have demonstrated that emotion enhances memory for contextual details, challenging the view that emotion impairs the ability to remember such information.
Researchers demonstrated that the circumstances where you can prevent forgetting contextual details, which not only disrupts the status quo at the theoretical level, but also has practical implications about what you can do to control, channel and capitalize on the emotions' energy to remember better.
In emotional situations, people often focus more on the main subject—the crashed car, the yelling stranger, the crying child—and less on peripheral information. In three interconnected studies, the researchers linked behavioural, attentional and brain imaging data to build a complete image of emotion's impact and account for this involuntary attention shift.
They found that emotion enhances the ability to retrieve contextual details.
In emotional situations that participants in the experiments accurately recalled, functional magnetic resonance imaging data showed evidence of crosstalk between emotion-processing and recollection-processing brain regions, boosting recollection of contextual details. This is contrary to the prevalent view that emotion impairs memory for these details by inhibiting recollection-processing brain regions.
Knowing how emotion impacts memories and how to manage them is a major step toward contextualizing memories, increasing well-being and alleviating clinical conditions like depression, anxiety and post-traumatic stress disorder.

A research team has shown how human and non-human primate hearts differ genetically. The study, published in Nature Cardiovascular Research, reveals evolutionary adaptations in human hearts and provides new insights into cardiac disease.
Humans are 98–99% genetically similar to chimpanzees. What then accounts for our differences? Over the years, researchers have shown that the regulation of gene expression—when, where, and by how many genes are switched on—is in large part responsible for our divergent evolutionary trajectories.
Now, researchers in the Cardiovascular and Metabolic Sciences Lab have unveiled surprising differences in gene expression in the hearts of humans and non-human primates. The research points to adaptations in the way genes are regulated that distinguish our hearts from those of our closest evolutionary relatives. It also serves as a warning against extrapolating research from animal hearts to human hearts.
One of the most surprising findings was how gene regulation in the human heart differs so much from other primates. In terms of anatomy, most mammalian hearts are similar. But we have many unique evolutionary innovations in terms of gene regulation or translation of proteins.
The researchers found hundreds of genes and microproteins—tiny proteins that have been previously identified in human organs but whose function has mostly been a mystery—present in human hearts but not in the hearts of other primates, rats or mice. Many of these human genes and microproteins are also abnormally expressed in heart failure, which suggests they could play important roles in cardiac function and disease and may present new targets for therapy.

How do people navigate social networks to understand and appreciate who knows what and who is connected to whom? With mental maps, according to a new study by researchers.
According to the researchers, the study showed for the first time that people create mental maps of the connections between acquaintances, friends, and friends of friends to navigate their social worlds. Social navigation, the team found, is similar to spatial navigation.
The cognitive process people use to navigate social networks appears to be similar to the cognitive process used by mice navigating a maze.
We know from decades of research that mice, and humans, build mental maps to understand their physical worlds. People seem to use maps to make sense of social environments as well.

Despite its importance for mathematics, the neuronal basis of the number zero in the human brain was previously unknown. Researchers have now discovered that individual nerve cells in the medial temporal lobe recognize zero as a numerical value and not as a separate category "nothing."
The results have now been published in the journal Current Biology.
The concept of the number zero has been central to the development of number systems and mathematics and is widely regarded as one of humanity's most important cultural achievements.
Unlike other numbers such as one, two or three, which represent countable quantities, zero means the absence of something countable and at the same time still has a numerical value.
In contrast to positive natural numbers, the concept of the number zero only emerged late in human history over the last two millennia. This is also reflected in childhood development, as children are typically only able to understand the concept of zero and associated arithmetic rules at around the age of six.
In the experiments conducted , there was a numerical distance effect in which neurons reacted weaker, but measurably, also to the neighboring number one.
So at the neuronal level, the concept of zero is not encoded as a separate category 'nothing,' but as a numerical value integrated with other, countable numerical values at the lower end of the number line.
For Arabic numerals, however, this effect was not found at either the neural or behavioral level. From this, the researchers recognize the importance of symbolic representations, for example through Arabic numerals, for the integration of the number zero on the number line in the human brain.

Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. Researchers have now discovered that this effect is reduced when bacteria form communities.
In a first-of-its-kind study, researchers compared a large number of drug-microbiome interactions between bacteria grown in isolation and those part of a complex microbial community. Their findings were recently published in the journal Cell.
For their study, the team investigated how 30 different drugs (including those targeting infectious or noninfectious diseases) affect 32 different bacterial species. These 32 species were chosen as representative of the human gut microbiome based on data available across five continents.
They found that when together, certain drug-resistant bacteria display communal behaviors that protect other bacteria that are sensitive to drugs. This "cross-protection" behavior allows such sensitive bacteria to grow normally when in a community in the presence of drugs that would have killed them if they were isolated.
Up to half of the cases where a bacterial species was affected by the drug when grown alone, it remained unaffected in the community.
The researchers then dug deeper into the molecular mechanisms that underlie this cross-protection. The bacteria help each other by taking up or breaking down the drugs. These strategies are called bioaccumulation and biotransformation respectively.
However, there is also a limit to this community strength. The researchers saw that high drug concentrations cause microbiome communities to collapse and the cross-protection strategies to be replaced by "cross-sensitization." In cross-sensitization, bacteria which would normally be resistant to certain drugs become sensitive to them when in a community—the opposite of what the authors saw happening at lower drug concentrations.
Just like the bacteria they studied, the researchers also took a community strategy for this study, combining their scientific strengths.

To grow and survive, tiny organisms such as yeast must sometimes adapt their nutrient sources in response to changes in the environment. FMI researchers have now found that yeast cells communicate with each other to use less favorable nutrients if they foresee a shortage of their favorite food. This communication is facilitated by secreted molecules that interact with a protein in mitochondria, the cells' energy factories.
The findings reveal a crucial mechanism that allows microorganisms to choose the right menu. The research is published in The EMBO Journal.
Previous research had identified specific molecules called Nitrogen Signaling Factors (NSFs) as essential components of the mechanism that yeast cells use to communicate.
The researchers now found that NSFs interact directly with a mitochondrial protein involved in metabolism, maximizing growth in response to an imminent change in nutrient availability. The findings unveil a key communication mechanism that allows yeast cells to be frugal with food. Strategies for growth and survival are conserved across species, and yeast has served as a tremendous model organism.
The researchers discovered that increasing NSFs levels lead to changes in the gene expression program of yeast cells, prompting them to switch to alternative nutrient sources.

Instead of nurturing their sick young, ant queens eat their infected offspring at the first sign of illness then "recycle" them into energy to produce new eggs, a new study led by the University of Oxford has shown. The findings have been published in Current Biology.
Eek! Nature and Universe don’t care what happens to which mass of atoms!
Ant queens typically found new colonies on their own, and at the early stages are highly vulnerable to their brood being wiped out by disease. Researchers at Oxford's Department of Biology theorized that killing off sick larvae before they become infectious could be a strategy used by queens to combat this threat.
To test this, the researchers presented founding queens of the black garden ant (Lasius niger) with larvae that had been infected with a fungal pathogen Metarhizium for 24 hours. At this point, the infection was lethal, but not yet transmissible. The queens cannibalized 92% of the infected larvae—leaving no remains—but only 6% of control larvae which had not been infected.
Once the queens find a sick larva in the brood pile they get to work immediately and spend several hours chewing them up until they're all consumed.
Despite the potential risk of infection, all queens survived after eating the infected larvae. The researchers suggest the queens may protect themselves by swallowing an acidic, antimicrobial venom which they produce from a special gland at the end of their abdomen. Indeed, some of the queens were seen massaging the opening of this gland during and after cannibalism.
The queens who cannibalized their infected larvae went on to lay 55% more eggs than non-cannibalizing control queens, indicating that the nutrients from the ingested offspring were recycled for reproduction.
Flynn Bizzell et al, Ant queens cannibalise infected brood to contain disease spread and recycle nutrients, Current Biology (2024). DOI: 10.1016/j.cub.2024.07.062
Deadly Storms have flooded recently large areas of central Europe and the UK, destroying homes and displacing thousands of people.
With the flooding of sub-stations, the scouring of the foundations of pylons and river embankment failures, the rainstorm has also caused power outages many miles away. This will create yet more disruption as sewage pumping stations stall, train and tram services halt and vehicle charging points fail.
The UK saw this ripple of infrastructure failure in the 2007 summer floods.
India too saw this ripple effect in this monsoon season.
All systems fail occasionally. But infrastructure is increasingly vulnerable to disruptions caused by extreme weather, which is being made more severe and frequent as a result of climate change.
Your home may not be in the path of the next storm but the infrastructure it relies on might be.
