A New Vaccine That Can Block HIV

Researchers at various reserach institutes has been working and successful in finding out a dru that can work against HIV virus and immune against it. The drug has worked against doses of HIV that were higher than  transmitted between humans, and works for at least eight months after injection.
A new drug led by the team of researchers at  Scripps Research Institute in the US, is found to be effective against doses of HIV-1, HIV-2 and SIV (simian immunodeficiency virus) that have been extracted from humans - including what researchers consider to be the ‘hardest-to-stop’ variants.
"Our compound is the broadest and most potent entry inhibitor described so far,” lead researcher Michael Farzan from the Scripps Institute said in a press release. "Unlike antibodies, which fail to neutralise a large fraction of HIV-1 strains, our protein has been effective against all strains tested, raising the possibility it could offer an effective HIV vaccine alternative.”
HIV infects a person by infecting his T lymphocyte, a type of white blood cells and injecting his own genetic material into to tranform it to HIV producing machine, thus making our immune acts against us.
The team has discovered  that a particular type of protein found on the surface of white blood cells can actually bind to the surface of the HIV virus in two different places simultaneously, which means that not only does the virus no longer have a chance to change the position of its receptors to escape, it’s also being blocked from entering the T lymphocyte cells.
"When antibodies try to mimic the receptor, they touch a lot of other parts of the viral envelope that HIV can change with ease," said one of the team, Matthew Gardner, from the Scripps Institute. "We've developed a direct mimic of the receptors without providing many avenues that the virus can use to escape, so we catch every virus thus far.”

"We are closer than any other approach to universal protection, but we still have hurdles, primarily with safety for giving it to many, many people,” Franzen told the BBC. One such concern is that no one really knows what the long-term implications would be for a person who is having an anti-HIV response being pumped around their body non-stop. The team will be looking into this when they get their human trials underway.

AI in Soap Manufacturing Industry

Machine learning (ML) has numerous potential applications in the soap manufacturing industry, contributing to process optimization, quality control, resource management, and more. Here are some examples: 1. Quality Control : ML algorithms can be trained to analyze images of soap bars to detect defects such as cracks, air bubbles, or inconsistent coloring. By automating the inspection process, manufacturers can ensure that only high-quality products reach the market, reducing waste and enhancing customer satisfaction. 2. Predictive Maintenance : ML models can analyze sensor data from manufacturing equipment to predict when maintenance is needed. By detecting potential issues before they cause equipment failure, manufacturers can minimize downtime and reduce repair costs. 3. Supply Chain Optimization : ML algorithms can analyze historical data on raw material prices, demand forecasts, and production schedules to optimize inventory management and procurement decisions. This helps minimize...

Goodbye, Oppurtunity. Nasa mars rover 'Opportunity' no longer resposding.

Opportunity, the intrepid NASA rover that spent 15 years on Mars climbing in and out of craters to gather evidence of the planet's watery past, has been brought down by tiny particles of dust. After weeks of trying to revive the veteran Mars rover in the wake of a blinding dust storm, NASA has given up on ever hearing from it again. It's a humble ending for a machine that survived a 300-million-mile journey through space, executed a hole-in-one landing, and set a record by driving more than 28 extraterrestrial miles. Opportunity's last transmission to Earth occurred on June 10 amid an epic Martian dust storm. Still, NASA engineers remained hopeful that when the dust settled, the rover would recharge its solar-powered batteries and resume its superlative mission. Opportunity landed on Mars in January 2004 for a mission that was supposed to last 90 Martian days. Its twin rover, Spirit, had landed three weeks earlier on the other side of the planet. "Wit...

Way better than X ray..

Medical techniques for looking inside our bodies have come a long way, but in the future it looks like doctors may be able to see absolutely everything going on under our skin. Researchers have invented a new kind of camera that can actually see through structures inside the human body, detecting light sources behind as much as 20 centimetres (7.9 inches) of bodily tissue. The current prototype, developed by researchers from the University of Edinburgh in the UK, is designed to work in conjunction with endoscopes – long, slender instruments that are often equipped with cameras, sensors and lights to peer inside hollow cavities inside the human body. Endoscopes are valuable tools for all sorts of medical procedures, but up until now it's been difficult to externally confirm exactly where in the body the instrument is looking, without resorting to things like X-ray scans. Now that's no longer a problem, due to the new camera's capability to detect sources of light inside ...
