         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!"

Pathogens are thriving in the plastisphere

Plastic pollution is creating a ‘plastisphere’: a widespread habitat that includes pathogenic viruses and antimicrobial-resistant bacteria, a group of environmental researchers highlights. The problem has no easy fix, but the ecosystems of the plastisphere must be thoroughly studied, with..., if we’re to mitigate the risks posed by the pathogens lurking within.

Comment by Dr. Krishna Kumari Challa yesterday

Taking cues from another successful Pitt project that used electrical stimulation of the spinal cord to restore arm function in individuals affected by stroke, scientists hypothesized that stimulating the motor thalamus—a structure nested deep in the brain that acts as a key relay hub of movement control—using DBS could help restore movements that are essential for tasks of daily living, such as object grasping.

However, because the theory has not been tested before, they first had to test it in monkeys, which are the only animals that have the same organization of the connections between the motor cortex and the muscles as humans.
To understand the mechanism of how DBS of the motor thalamus helps improve voluntary arm movement and to finesse the specific location of the implant and the optimal stimulation frequency, researchers implanted the FDA-approved stimulation device into monkeys that had brain lesions affecting how effectively they could use their hands.

As soon as the stimulation was turned on, it significantly improved activation of muscles and grip force. Importantly, no involuntary movement was observed.

To verify that the procedure could benefit humans, the same stimulation parameters were used in a patient who was set to undergo DBS implantation into the motor thalamus to help with arm tremors caused by brain injury from a serious motor vehicle accident that resulted in severe paralysis in both arms.

As soon as the stimulation was turned on again, the range and strength of arm motion was immediately improved. The participant was able to lift a moderately heavy weight and reach, grasp and lift a drinking cup more efficiently and smoothly than without the stimulation.

To help bring this technology to more patients in the clinic, researchers are now working to test the long-term effects of DBS and determine whether chronic stimulation could further improve arm and hand function in individuals affected by traumatic brain injury or stroke.

Deep brain stimulation shows immediate improvement in arm and hand function post-brain injury

Deep brain stimulation may provide immediate improvement in arm and hand strength and function weakened by traumatic brain injury or stroke, researchers reported recently in Nature Communications.

Encouraging results from extensive tests in monkeys and humans open a path for a new clinical application of an already widely used brain stimulation technology and offer insights into neural mechanisms underlying movement deficits caused by brain injury.

Brain lesions caused by serious brain trauma or stroke can disrupt neural connections between the motor cortex, a key brain region essential for controlling voluntary movement, and the muscles. Weakening of these connections prevents effective activation of muscles and results in movement deficits, including partial or complete arm and hand paralysis.

To boost the activation of existing but weakened connections, researchers proposed using deep brain stimulation (DBS), a surgical procedure that involves placing tiny electrodes in specific areas of the brain to deliver electrical impulses that regulate abnormal brain activity. Over the past several decades, DBS has revolutionized the treatment of neurological conditions such as Parkinson's disease by providing a way to control symptoms that were once difficult to manage with medication alone.

DBS has been life-changing for many patients. Now, thanks to ongoing advancements in the safety and precision of these devices, DBS is being explored as a promising option for helping stroke survivors recover their motor functions.

There arethree main types of blood cancers:

  • Leukemias are cancers of the white blood cells in the bone marrow and blood and, rarely, the lymphatic system. The abnormal production of white blood cells can interfere with the body's ability to fight infections. There are several types of leukemia, including  (ALL),  (AML),  (CLL) and  (CML).
  • Lymphomas are cancers of immune cells called lymphocytes. The two main types of lymphoma are Hodgkin lymphoma and non-Hodgkin lymphoma. These cancers can be slow-growing or fast-growing, and can be found in various parts of the body, including the lymph nodes, spleen and bone marrow.
  • Myeloma, also known as multiple myeloma, is a cancer of the plasma cells, immune cells that are found in the . When myeloma cells multiply, this can lead to bone damage, anemia, kidney problems, high blood calcium levels and a weakened immune system.

Common symptoms include: Fever, Drenching night sweats, Persistent fatigue, Weakness Bone/joint pain, Unexplained weight loss, Swollen lymph nodes, liver or spleen ,Anemia.

The fungal infection valley fever

Some areas of the U.S. are experiencing a recent uptick in cases of a fungal lung infection called valley fever. 

Valley fever is a fungus. It lives in the soil, and it's endemic, or known to be in regions in the Southwest, such as Arizona, lower California, New Mexico and parts of Mexico.

Valley fever is transmitted via inhalation of spores from the soil, especially during dusty months or high-dust exposure, such as in construction zones.

"Initial symptoms of valley fever can be cough, difficulty breathing, shortness of breath, sometimes a rash and joint aches, and also associated fatigue.

Most people with a healthy immune system can fight off valley fever naturally, but those with immune problems or on certain medications may be at higher risk.

The people getting really significant illness are those that have immune problems, or if you have diabetes or if you're on immune-suppressing medications can really put you at risk.

The best way to prevent valley fever is to avoid high-dust exposure.

If at all possible, if it's really dusty outside and you can really see the dust in the air, try to stay indoors and try to avoid that inhalation of that high-dust exposure.

Six dead from Marburg viral disease in Rwanda

Six people have been killed in Rwanda in an outbreak of Marburg virus, a highly infectious hemorrhagic fever similar to Ebola, the country's health ministry said recently.

The highly virulent microbe causes severe fever, often accompanied by bleeding and organ failure.

Marburg is part of the so-called filovirus family that also includes Ebola, which has wreaked havoc in several previous outbreaks in Africa.

Neighboring Tanzania reported cases of the disease in 2023, while Uganda experienced its last outbreak in 2017. The three countries share porous borders.

The suspected natural source of the Marburg virus is the African fruit bat, which carries the pathogen but does not fall sick from it.

The animals can pass the virus to primates in close proximity, including humans, and human-to-human transmission then occurs through contact with blood or other body fluids.

Fatality rates in confirmed cases have ranged from 24 percent to 88 percent in previous outbreaks, depending on the virus strain and case management, according to the World Health Organization (WHO).

There are currently no vaccines or antiviral treatments, but potential treatments, including blood products, immune and drug therapies, as well as early candidate vaccines, are being evaluated.

 Rare human death from rabies

A Minnesota resident who came into contact with a bat in July died of rabies, the state's department of health announced Friday.

The person's death marks a rare occurrence, as fewer than 10 people in the the U.S. die from rabies each year, according to the U.S. Centers of Disease Control and Prevention. The person is over the age of 65 and was exposed to a bat in western Minnesota in July, the Minnesota Department of Health said.

CDC officials confirmed the rabies diagnosis at its lab in Atlanta on Sept. 20. In a news release, the state health department said it was working to evaluate whether more people were exposed to the disease, but said there was no ongoing risk to the public

Officials said the fatal case advised the public to avoid contact with bats, whose teeth are so tiny that a bite may not be felt or even leave a noticeable mark.

Rabies is caused by a virus that invades the central nervous system and is usually fatal in animals and humans. If left untreated, rabies is almost always fatal. But rabies treatment has proven to be nearly highly effective at preventing the disease after an exposure, state health officials said. Treatment must be started before symptoms of rabies appear, they added.

The number of rabies-related human deaths in the U.S. has declined from more than 100 annually in the early 1900s to less than five cases annually in recent years, the health department. About 70% of infections acquired in the country are attributed to bat exposures.

Patient with type 1 diabetes functionally cured using stem cell injections

A team of medical researchers affiliated with a large number of institutions in China has functionally cured a female patient with type 1 diabetes by injecting her with programmed stem cells.

For their study published in the journal Cell, the group extracted cells from the patient, reverted them to a pluripotent state, programmed them to grow into pancreatic islets, and then injected them back into her abdomen.

For unknown reasons, some people experience an immune attack that results in the destruction of islets in the pancreas that are responsible for making insulin. These incidents typically happen during the teen years, which is why the disease is also known as juvenile diabetes.

Because the islets are destroyed, any cure for the disease must involve replacing the islets somehow, either through transplantation from a donor, or in this new example, by using the person's own cells as the basis for creating pluripotent stem cells, which can be programmed to grow into replacement islets.

In this new effort, the researchers collected cells from three type 1 diabetes patients—all the cells were reverted to a pluripotent state and then programmed to grow into pancreatic islets. The researchers note that they modified the standard approach by exposing the cells to certain molecules rather than introducing proteins. The treatment process for the patients was staggered over time so that findings from the first patient could be applied to the second and then the third.

In a procedure lasting approximately 30 minutes, the researchers injected 1.5 million of the islets they had grown into the abdomen of the first patient, a 25-year-old woman. Placing them in the abdomen allowed for easy monitoring and removal if necessary. Two and a half months later, testing showed the patient was producing enough of her own insulin to stop injections.

After a year, she was still producing her own insulin. The research team notes that the patient was already receiving immunosuppressant drugs due to a prior liver transplant; thus, it is still not known if her immune system will replicate the type of attack that led her to have type 1 diabetes in the first place.

Well-designed AI tools can help clean toxic comments up

Imagine scrolling through social media  only to be interrupted by insulting and harassing comments. What if an artificial intelligence (AI) tool stepped in to remove the abuse before you even saw it?

This isn't science fiction. Commercial AI tools like ToxMod and Bodyguard.ai are already used to monitor interactions in real time across social media and gaming platforms. They can detect and respond to toxic behavior.

The idea of an all-seeing AI monitoring our every move might sound Orwellian, but these tools could be key to making the internet a safer place.

However, for AI moderation to succeed, it needs to prioritize values like privacy, transparency, explainability and fairness. So can we ensure AI can be trusted to make our online spaces better? Two recent research projects into AI-driven moderation show this can be done—with more work ahead.

A cooling system that works on gravity instead of electricity

This device needs no electricity, as it extracts water from the air using nothing more than gravity and relies on cheap, readily available materials.

Along with keeping the solar cells and other semiconductor technologies cool, the water can be repurposed for irrigation, washing, cooling buildings on which the solar cells are placed, and other applications.

Scientists estimate that the atmosphere contains six times more water than all the fresh water in the rivers combined. This water can be collected by atmospheric water harvesting technologies.

While these technologies work reasonably well, in arid environments they require electricity to harvest practical amounts of water. This demand risks deterring the adoption of solar cells in rural regions , where electricity infrastructure is costly.

One reason for the low efficiency is that the water adheres to the surface of the harvesting device.

Researchers found that by adding a lubricant coating that is a mix of a commercial polymer and silicon oil, they could collect more water by relying on only gravity.

The system doesn't consume any electricity, leading to energy savings. Moreover, it doesn't rely on any mechanical parts like compressors or fans, reducing the maintenance over traditional systems, leading to further savings.
