A Non-Destructive Method of Analysing Molecules in Cells

Fibre laser microscopy to be used in clinical applications. When investigating how tumors grow, or how pharmaceuticals affect different types of cells, researchers have to understand how molecules within a cell react – and interact. This is possible with modern laser microscopy. Until now, however, molecules in cell specimens had […]

Researchers use brain imaging to demonstrate weaker neural suppression in individuals with autism

People with an autism spectrum disorder, or ASD, may experience sensory hypersensitivity more often than people without ASD, according to the National Autism Association. Among other responses, this hypersensitivity can lead to “sensory overload,” when sensory systems like vision or hearing are “overwhelmed” by stimuli. Scientists do not fully understand […]

Antibody designed to recognise pathogens of Alzheimer’s disease

Researchers have found a way to design an antibody that can identify the toxic particles that destroy healthy brain cells – a potential advance in the fight against Alzheimer’s disease. Their method is able to recognise these toxic particles, known as amyloid-beta oligomers, which are the hallmark of the disease, […]

Clog Loss: Advance Alzheimer’s Research with Stall Catchers

5.8 million Americans live with Alzheimer’s dementia, including 10% of all seniors 65 and older. Scientists at Cornell have discovered links between “stalls,” or clogged blood vessels in the brain, and Alzheimer’s. Stalls can reduce overall blood flow in the brain by 30%. The ability to prevent or remove stalls may […]

New technology enables fast protein synthesis

Many proteins are useful as drugs for disorders such as diabetes, cancer, and arthritis. Synthesizing artificial versions of these proteins is a time-consuming process that requires genetically engineering microbes or other cells to produce the desired protein.

Two paths better than one for treating patients with heart stents, study shows

Pairing a blood-thinning drug with aspirin daily for patients who have an angioplasty with a stent can contribute to better health outcomes, including lower risk of death, than aspirin alone, according to a recent study by cardiologists at the University of Alberta and Mazankowski Alberta Heart Institute. Led by Kevin […]

Blocking tumor signals can hinder cancer’s spread

For most people who die of cancer, the spread of the initial tumor is to blame. “Metastasis is what kills most cancer patients,” says Serge Fuchs, a professor in Penn’s School of Veterinary Medicine. “Yet there are not many, if any, drugs that specifically target metastatic processes.” In a paper in […]

Engineers develop device to automate tissue manufacturing for muscle repair

In recent wars, about 53,000 U.S. military veterans have suffered serious injuries, often involving large amounts of tissue loss. Many more Americans also suffer from long-term injuries resulting from car crashes, accidents, and surgeries. Many of these injuries are disfiguring and debilitating. Now, imagine if lost skeletal muscle could be […]

Coveting yeast? It's much more than a loaf of bread

UC Riverside engineers are transforming yeast, both the domesticated kind used to make bread and beer and lesser-known wild species, so it can be used in a variety of new ways — including fighting cancer. Yanran Li, a UC Riverside assistant professor of chemical and environmental engineering, is working with […]

Exploiting viruses to attack cancer cells

An adenovirus is now better able to target and kill cancer cells due to the addition of an RNA stabilizing element. Hokkaido University scientists have made an adenovirus that specifically replicates inside and kills cancer cells by employing special RNA-stabilizing elements. The details of the research were published in the […]

Turning on the ‘off switch’ in cancer cells

A team of scientists led by the Case Comprehensive Cancer Center and the University of Michigan Rogel Cancer Center has identified the binding site where drug compounds could activate a key braking mechanism against the runaway growth of many types of cancer. The discovery marks a critical step toward developing a potential new class […]

New Liver Cancer Research Targets Non-Cancer Cells to Blunt Tumor Growth

By targeting senescent cells using “senotherapy” researchers can greatly reduce tumors in models. “Senotherapy,” a treatment that uses small molecule drugs to target “senescent” cells, or those cells that no longer undergo cell division, blunts liver tumor progression in animal models according to new research from a team led by Celeste […]

At-home screening for ovarian, breast cancers is effective

At-home genetic-testing kits for breast and ovarian cancer risk are just as effective, and in some cases even more so, than the typical protocol for genetic testing, which requires repeated office visits and counseling, according to a study led by UW Medicine researchers. The results, published by the American Society of Clinical […]

Study reveals first evidence inherited genetics can drive cancer’s spread

Sometimes cancer stays put, but often it metastasizes, spreading to new locations in the body. It has long been suspected that genetic mutations arising inside tumor cells drive this potentially devastating turn of events. Now researchers have shown for the first time that our own pre-existing genetics can promote metastasis. […]
