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 […]

Scientists have identified a group of drugs that may help stop a leading cause of vision loss after making an unexpected discovery that overturns a fundamental belief about DNA. The drugs, known as nucleoside reverse transcriptase inhibitors, or NRTIs, are commonly used to treat HIV. The new discovery suggests that […]

The immune system is an extremely complex organ system capable of fighting disease. However, it can also create disease because immune cells may—so to speak—run riot and start attacking the healthy cells of the body. This very delicate balance has always fascinated Professor Sine Reker Hadrup, and she has embarked […]

A Canadian-led research project has confirmed that it is safe to procure organs for transplant from dying patients once the heart has stopped for a full five minutes, in newly published findings in the New England Journal of Medicine. The researchers monitored blood pressure and electrocardiographic (ECG) waveforms in 631 dying patients following […]

Blocking seizures after a head injury could slow or prevent the onset of dementia, according to new research by University of Alberta biologists. “Traumatic brain injury is a major risk factor for dementia, but the reason this is the case has remained mysterious,” said Ted Allison, co-author and professor in the Department […]

Both inactivated and live-attenuated vaccines generally produce an adequate immune response and are safe to use in children suffering from autoimmune diseases treated with all but the most potent immunosuppressants, according to a research review. The team examined 37 original articles: 25 studied the inactivated vaccines influenza; hepatitis A virus; […]
