Gold Nanotubes To Cure Cancer

Scientists has found out that Gold nanotubes can be used in fighting Cancer; internal nanoprobes for high-resolution imaging; drug delivery vehicles; and agents for destroying cancer cells.
The article published in the journal, Advanced Functional Materials, details the first successful demonstration of the biomedical use of gold nanotubes in a mouse model of human cancer.
 Dr Sunjie Ye, who is based in both the School of Physics and Astronomy and the Leeds Institute for Biomedical and Clinical Sciences at the University of Leeds, said:  “High recurrence rates of tumours after surgical removal remain a formidable challenge in cancer therapy. Chemo- or radiotherapy is often given following surgery to prevent this, but these treatments cause serious side effects.
Gold nanotubes – that is, gold nanoparticles with tubular structures that resemble tiny drinking straws – have the potential to enhance the efficacy of these conventional treatments by integrating diagnosis and therapy in one single system.”
The study’s corresponding author Professor Steve Evans, from the School of Physics and Astronomy at the University of Leeds, said: “Human tissue is transparent for certain frequencies of light – in the red/infrared region. This is why parts of your hand appear red when a torch is shone through it.
“When the gold nanotubes travel through the body, if light of the right frequency is shone on them they absorb the light. This light energy is converted to heat, rather like the warmth generated by the Sun on skin. Using a pulsed laser beam, we were able to rapidly raise the temperature in the vicinity of the nanotubes so that it was high enough to destroy cancer cells.”
In order to see the gold nanotubes in the body, the researchers used a new type of  imaging technique called ‘multispectral optoacoustic tomography’ (MSOT) to detect the gold nanotubes in mice, in which gold nanotubes had been injected intravenously. It is the first biomedical application of gold nanotubes within a living organism. It was also shown that gold nanotubes were excreted from the body and therefore are unlikely to cause problems in terms of toxicity, an important consideration when developing nanoparticles for clinical use. 
“The nanotubes can be tumour-targeted and have a central ‘hollow’ core that can be loaded with a therapeutic payload. This combination of targeting and localised release of a therapeutic agent could, in this age of personalised medicine, be used to identify and treat cancer with minimal toxicity to patients.”

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...

Telescopic Contact Lens For Visually Impaired People

See far distance just by winking your eyes. A team of engineers have designed a telescopic contact lens that can switch between normal and magnefied vision.  The Researchers at  San Jose, California has built a prototype pf lens that could one day help people with visual impairment  to see. The lenses might be particularly useful with age-related macular degeneration, a debilitating condition in which people gradually lose their central vision. It is the leading cause of visual impairment and affect millions worldwide. The contact lens developed by Ford’s team is one millimeter thick. Researchers used aluminum mirrors, fit tightly together, to create a ring-shaped telescope embedded in the contact lens. The center of the lens allows for normal, non-magnified vision.  Its periphery, where the telescope is located, magnifies images 2.8 times. Switching between normal and magnefied vision Without the glasses, the contact lenses superimpose both normal and magn...

Top 3 Fastest Hydrogen Powered Car

When it comes to racing using hydrogen powered car, this top three car will win the show. Hydrogen powered car uses hydrogen gas as a fuel which combust with oxygen to form water. #3. Aston Martin Rapide :  British luxury marque ASTON MARTIN  introduced AM Rapide S in early 2010.  The Rapide is powered by a 5,935 cc V12 engine , producing 470 bhp and torque of 443 lbf·ft (601 N·m). It is Rear-wheel drive  and has a six- speed Touchtronic automatic. The Rapide can reach a top speed of 188.5 mph (303 km/h),  and accelerate 0-100 km/h (62 mph) in 5.3 seconds, or 0-60 mph (97 km/h) in 5.0 seconds. #2. BMW H2R : This car built by BMW uses liquid hydrogen as a fuel. The H2R’s 6.0-liter V-12 engine, which draws on BMW 's Valvetronic  and Double-Vanos  technology, is based on the 760i’s gasoline-fueled powerplant. This H2-powered high performer generates 232 horsepower (173 kW), helping it t...
