All things being equal, large, long-lived animals should have the highest risk of cancer. The calculation is simple: Tumors grow when genetic mutations cause individual cells to reproduce too quickly. A long life creates more opportunities for those cancerous mutations to arise. So, too, does a massive body: Big creatures […]

For the millions of Americans living with Alzheimer's disease and related dementias (ADRD), access to specialized geriatric providers — such as geriatricians — could improve the quality of their care. However, these providers are often in short supply, raising questions about access to the unique care that dementia patients need. […]

Researchers can now determine the age and sex of living beluga whales in Alaska’s Cook Inlet thanks to a new DNA-based technique that uses information from small samples of skin tissue. Accurate age estimates are vital to conservation efforts for Cook Inlet belugas, which were listed as endangered following a significant population […]

In biological cells, proteins are everywhere: these building blocks of life perform countless important functions. A human cell contains thousands of different proteins at any given time, often with copies of each protein type present in their hundreds or even thousands simultaneously. In recent years, researchers have succeeded in using […]

We are gradually learning more about the cells of the human body than any researcher has ever dared to dream of. But what’s the purpose? The mere thought of what one plunges into when deciding to research cells is mind-blowing: The human body contains 37 trillion cells, plus/minus a few […]

A team of scientists from Japan have found success in growing small intestinal cells, akin to those found in the human body, from human-induced pluripotent stem cells. The scientists used a procedure they previously developed on embryonic stem cells for this discovery. They claim that the grown cells can be […]

Eating too much fat and sugar as a child can alter your microbiome for life, even if you later learn to eat healthier, a new study in mice suggests. The study by UC Riverside researchers is one of the first to show a significant decrease in the total number and […]

It took the University of Nebraska–Lincoln’s Ruiguo Yang far longer to devise a way to put that connection to the test, to ratchet up the stress with unprecedented precision, all while measuring the strain it could endure before reaching a breaking point. The pair in question? Human cells. Their connection? A […]

Lawrence Livermore National Laboratory (LLNL) scientists have developed a new method for 3D printing living microbes in controlled patterns, expanding the potential for using engineered bacteria to recover rare-earth metals, clean wastewater, detect uranium and more. Through a novel technique that uses light and bacteria-infused resin to produce 3D-patterned microbes, the […]

New research has found that men who have the Western world’s most common genetic disorder are more likely to develop dementia, compared to those without the faulty genes. Researchers at the University of Exeter and the University of Connecticut have previously found that men with two faulty genes that cause […]

Hormone therapy commonly is given as a targeted treatment for women whose cancer cells carry receptors for estrogen. But the therapy only works for about half of all patients. Until now, there hasn’t been a good way to reliably predict who will benefit and who will not. Researchers at Washington […]

If there was a superhero who relieved pain, millions would be overjoyed. More than 100 million Americans suffer from chronic pain, costing in excess of $650 billion a year in medical treatments and lost productivity, according to a report from the Institute of Medicine. Vulnerable populations are far more likely to develop chronic pain […]
