Genomic signature could lead to new early-detection cancer test

Detecting cancer when it's still in the early stages of development is a difficult task, but an extremely important one, with the chances of effective treatment being much higher the quicker it's caught. Now, a team of researchers from the National Institute of Health (NIH) has identified a signature of tumor DNA that occurs, and is detectable, in five different cancers – a discovery that could lead to a simple early detection blood test.Read More

Electrical contact lens eyes glucose monitoring and augmented reality

Smart glasses haven't quite taken off as some might have hoped, but that doesn't mean another form of eyewear can't offer users a worthy augmented reality experience. Australian scientists have developed an electrically conductive contact lens with the potential to host miniature computer displays and sensors to help monitor health.Read More

Clearing out damaged cells in mice extends lifespan by up to 35 percent

As we age, cells within our bodies can become damaged. As a way of helping prevent cancers developing, a biological mechanism called cellular senescence stops these damaged cells from dividing. Researchers at Mayo Clinic have now shown that clearing these senescent cells from the body of mice can improve health and extend their lifespan by up to 35 percent without any apparent adverse side effects.Read More

Cultured liver cell microreactor might replace animal testing

Finding alternatives to animal testing is an important endeavor. While the practice has been banned in the cosmetic products industry since 2013, it's still a central part of evaluating the effectiveness and dangers of new medication, with researchers usually using laboratory rodents to test out their latest drugs. Now, a team lead by scientists at Germany's Fraunhofer Institute for Cell Therapy and Immunology has created a microbioreactor that has the potential to provide medication testing using cultured liver cells rather than animals.Read More

Improved DNA tech could replace antibodies in detecting and treating diseases

A team of researchers from the Institute of Bioengineering and Nanotechnology at the Agency for Science, Technology and Research (A*STAR) has worked to develop an efficient technology that uses DNA to detect and treat infectious diseases. Improving upon an existing method, the research makes use of single-stranded DNA molecules called aptamers, and it could be used to treat cancer.Read More

New pain-relief drug shapes as less addictive alternative to morphine

Opiates have brought pain relief to humankind for hundreds of years, but they don't come without consequences. Motor impairment and respiratory depression are a couple of potential side effects, but from opium-dependent Chinese of the mid-19th century to the morphine-riddled soldiers of the Vietnam War, the risk of addiction remains the biggest problem. Researchers have now developed a new painkiller they claim to be as strong as morphine, but without much of this unwanted baggage.Read More

Natural food additive found to block skin cancer cells in mice

A latin American seed once used by Mayans as body paint and today as an orange food coloring in your cheddar cheese may prove useful in the fight against skin cancer. Scientists have found that a compound found in natural food additive annatto prevents the formation of cancer cells resulting from UV radiation in mice, and are now exploring whether annatto-rich diets can prevent similar sun damage in humans.

Gene-editing tool may prevent blindness

A team of researchers is working to turn the powerful CRISPR gene-editing tool towards treating a serious eye disease. Early results are promising, with the team successfully correcting the mutation that causes the condition in cells outside the body.Read More

Lab-made liver tissue may be used for drug screening

Laboratory-engineered liver tissue could be extremely useful, helping doctors to screen new drugs, and it could even one day be used for transplants. Unfortunately, it's also very difficult to replicate the organ's complex structure and functions outside of the human body. Now, researchers from China's Northwest A&F University have managed to construct artificial tissue that's proving effective at mimicking the real thing.Read More
