Scientists Identify Gene Required for Nerve Regeneration | Genetics A gene that is associated with regeneration of injured nerve cells has been identified by a team of researchers led by Prof Melissa Rolls of Penn State University. In fruit flies with two normal copies of the spastin gene, a team of scientists led by Prof Melissa Rolls of Penn State University found that severed axons were able to regenerate. However, in fruit flies with two or even only one abnormal spastin gene, the severed axons were not able to regenerate (Melissa Rolls / Penn State University) The team has found that a mutation in a single gene can entirely shut down the process by which axons – the parts of the nerve cell that are responsible for sending signals to other cells – regrow themselves after being cut or damaged. “We are hopeful that this discovery will open the door to new research related to spinal-cord and other neurological disorders in humans,” said Prof Rolls, who co-authored a paper published online in the journal Cell Reports.
Potential 'universal' blood test for cancer discovered | DoxCole The Lymphocyte Genome Sensitivity (LGS) test looks at white blood cells and measures the damage caused to their DNA when subjected to different intensities of ultraviolet light (UVA), which is known to damage DNA. The results of the empirical study show a clear distinction between the damage to the white blood cells from patients with cancer, with pre-cancerous conditions and from healthy patients. (Stock image). Researchers from the University of Bradford have devised a simple blood test that can be used to diagnose whether people have cancer or not. The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Early results have shown the method gives a high degree of accuracy diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer.

UCI, fellow chemists find a way to unboil eggs Irvine, Calif., Jan. 23, 2015 – UC Irvine and Australian chemists have figured out how to unboil egg whites – an innovation that could dramatically reduce costs for cancer treatments, food production and other segments of the $160 billion global biotechnology industry, according to findings published today in the journal ChemBioChem. “Yes, we have invented a way to unboil a hen egg,” said Gregory Weiss, UCI professor of chemistry and molecular biology & biochemistry. “In our paper, we describe a device for pulling apart tangled proteins and allowing them to refold. We start with egg whites boiled for 20 minutes at 90 degrees Celsius and return a key protein in the egg to working order.” Like many researchers, he has struggled to efficiently produce or recycle valuable molecular proteins that have a wide range of applications but which frequently “misfold” into structurally incorrect shapes when they are formed, rendering them useless.
How to Make The Giant Cancer-Fighting Salad: Chris Wark - The Truth About Cancer Ty Bollinger is a happily married husband, the father of four wonderful children, devoted Christian, best-selling author, medical researcher, talk radio host, health freedom advocate, former competitive bodybuilder and also a certified public accountant. After losing several family members to cancer (including his mother and father), Ty refused to accept the notion that chemotherapy, radiation, and surgery were the most effective treatments available for cancer patients. He began a quest to learn all he possibly could about alternative cancer treatments and the medical industry. Ty has now made it his life mission to share the most remarkable discovery he made on his quest: the vast majority of all diseases (including cancer) can be easily prevented and even cured without drugs or surgery. Ty speaks frequently to health groups, at seminars, expos, conferences, churches, and is a regular guest on multiple radio shows and writes for numerous magazines and websites.
7 Incredible Inventions by Teenage Wunderkinds When many of us were in our teens, work for science fairs comprised cut and paste displays on colorful presentation boards, and our hobbies weren't exactly about to change the world. But across the globe, teenagers with creative, scientific minds are already devising extraordinary devices, revolutionary materials and renewable technologies that might just change our planet for the greener. Click through to see some of their most incredible inventions - from bioplastics made from bananas to pee-powered energy generators and an ocean cleanup array to rid the world's oceans of waste. An Ocean Clean Up Array to Remove 7,250,000 Tons of Plastic From the World’s Oceans When we first covered Boyan Slat’s Ocean Cleanup Array it generated a phenomenal amount of excitement, as well as debate. The 19-year-old Dutch aerospace engineering student devised the array to be dispatched to the world’s garbage patches, with an initial estimate the the oceans could be cleaned up in around 5 years.
Dandelion Weed Can Boost Your Immune System And Cure Cancer Dandelion has been used medicinally since ancient times for its various health benefits. However, the most powerful benefit to come out of this common weed is something that medical researchers are super excited to have "discovered" - which is its potential to cure cancer! proverbsthirtyonewoman.blogspot.com This potent root builds up blood and immune system- cures prostate, lung, and other cancers better than chemotherapy. According to Dr. Carolyn Hamm from the Windsor Regional Cancer Centre in Ontario, Canada, dandelion root extract was the only thing that helped with chronic myelomonocytic leukemia. John Di Carlo, who at the time was a 72-year old cancer patient at the hospital, was sent home to live out his final days after all efforts failed to treat his leukemia. Screenshot via YouTube Recent studies have shown that dandelion root extract can work very quickly on cancer cells, as was evidenced in Di Carlo's case. Dr. Sponsored Sources: Dr.
Does DNA Emit Light? Dan Eden for viewzone.com An incredible story! I get lots of suggestions for stories, and I really appreciate them. I had this same experience this week when I was sent an article where a Russian (again) scientist, Pjotr Garjajev, had managed to intercept communication from a DNA molecule in the form of ultraviolet photons -- light! But this was just the beginning. Dr. I tried to find a scientific journal that had this experiment. Fritz-Albert Popp thought he had discovered a cure for cancer. It was 1970, and Popp, a theoretical biophysicist at the University of Marburg in Germany, had been teaching radiology -- the interaction of electromagnetic (EM) radiation on biological systems. He'd been examining two almost identical molecules: benzo[a]pyrene, a polycyclic hydrocarbon known to be one of the most lethal carcinogens to humans, and its twin (save for a tiny alteration in its molecular makeup), benzo[e]pyrene. Why Ultra-violet light? Photorepair Light inside the body Comments: John B. Dr.
Scientists in Amsterdam Just Destroyed Breast Cancer Tumors in 11 Days Without Chemo - ORGANIC AND HEALTHY Scientists in Europe may have found a breakthrough for the most common cancer in women. Around 1 in 8 American women will develop breast cancer in their lifetime; the clinical trial may have found a way to rid us of it once and for all in the future. Breast Cancer Breakthrough Research presented by Professor Nigel Bundred at the European Breast Cancer Conference in Amsterdam revealed that they had tested the effectiveness of a pair of drugs known as Herceptin (a.k.a trastuzumab) and Lapatinib. The two drugs are commonly used in breast cancer treatment already, but this is the first time they had been combined together and used before surgery and chemotherapy. Funded by Cancer Research UK, they aimed to use these drugs to combat a protein called HER2 (human epidermal growth factor receptor 2) which affects the growth and division of cancer cells. What also makes this treatment so appealing is the fact that it eliminates the need for chemotherapy and surgery. Study Results
Flowers get an electrifying buzz out of visiting bees - life - 21 February 2013 Plants could turn out to be one of the more chatty organisms. Recent studies have shown they can communicate with a surprising range of cues. Now it turns out they could be sending out electrical signals, too. As they fly through the air, bees – like all insects – acquire a positive electric charge. Flowers, on the other hand, are grounded and so have a negative charge. To test the idea, the team created artificial flowers, filling some with sucrose and others with quinine, a substance bees don't feed on. "That was the first hint that had us jumping up and down in the lab," says Robert. Next, his team looked at whether the bees were influenced by the shape of a flower's electric field, which is determined by the flower's shape. Ruthless evolution The researchers don't know exactly what information is contained in the flowers' electrical signals, but they speculate that flowers could evolve different shaped fields in their competition to attract pollinators.

Could turmeric really boost your health? Image copyright iStock Bold health claims have been made for the power of turmeric. Is there anything in them, asks Michael Mosley. Turmeric is a spice which in its raw form looks a bit like ginger root, but when it's ground down you get a distinctive yellowy orange powder that's very popular in South Asian cuisine. These days, thanks to claims that it can improve everything from allergies to depression, it's become incredibly trendy, not just cooked and sprinkled on food but added to drinks like tea. Now I'm usually very cynical about such claims, but in the case of turmeric I thought there could be something to it. Thousands of scientific papers have been published looking at turmeric and curcumin in the laboratory - some with promising results. Find out more Michael Mosley is one of the presenters of Trust Me, I'm A Doctor, broadcast on Thursdays at 20:00 BST on BBC Two - catch up on BBC iPlayer This is exactly the sort of situation where we on Trust Me like to make a difference.
Human Cells have Electric Fields as Powerful as Lighting Bolts -A Galaxy Insight Using newly developed voltage-sensitive nanoparticles, researchers have found that the previously unknown electric fields inside of cells are as strong, or stronger, as those produced in lightning bolts. Previously, it has only been possible to measure electric fields across cell membranes, not within the main bulk of cells, so scientists didn't even know cells had an internal electric field. This discovery is a surprising twist for cell researchers. University of Michigan researchers led by chemistry professor Raoul Kopelman encapsulated voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter. "They have developed a tool that allows you to look at cellular changes on a very local level," said Piotr Grodzinski, director of the National Cancer Institute Alliance for Nanotechnology in Cancer in Technology Review. Kopelman has developed encapsulated voltage-sensitive dyes that aren't hydrophobic and can operate anywhere in the cell, rather than just in membranes.

Male and female brains wired differently, scans reveal | Science Scientists have drawn on nearly 1,000 brain scans to confirm what many had surely concluded long ago: that stark differences exist in the wiring of male and female brains. Maps of neural circuitry showed that on average women's brains were highly connected across the left and right hemispheres, in contrast to men's brains, where the connections were typically stronger between the front and back regions. Ragini Verma, a researcher at the University of Pennsylvania, said the greatest surprise was how much the findings supported old stereotypes, with men's brains apparently wired more for perception and co-ordinated actions, and women's for social skills and memory, making them better equipped for multitasking. "If you look at functional studies, the left of the brain is more for logical thinking, the right of the brain is for more intuitive thinking. So if there's a task that involves doing both of those things, it would seem that women are hardwired to do those better," Verma said.
