Imaging Alzheimer’s

Amyloid-beta and tau are the two key abnormal protein deposits that accumulate in the brain during the development of Alzheimer’s disease. Detecting the buildup of these proteins at an early stage may allow clinicians to intervene before the condition has a chance to take hold. A team led by Harvard […]

Fecal microbiota transplants help patients with advanced melanoma respond to immunotherapy

For patients with cancers that do not respond to immunotherapy drugs, adjusting the composition of microorganisms in the intestines — known as the gut microbiome — through the use of stool, or fecal, transplants may help some of these individuals respond to the immunotherapy drugs, a new study suggests. Researchers […]

How elephants evolved to become big and cancer-resistant

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 […]

Obtaining specialist care may be harder for rural and lower-income Alzheimer’s patients

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. […]

New DNA-based technique allows researchers to determine age of living beluga whales in Alaska

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 […]

Detecting functional changes at the proteome level

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 […]

Researchers want to map your cells. All 37 trillion of them!

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 […]

First-of-its-kind system measures resilience, breakage of cellular bridge

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 […]

Lab 3D-prints microbes to enhance biomaterials

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 […]

Dementia rates higher in men with common genetic disorder haemochromatosis

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 […]

Imaging identifies breast cancer patients unlikely to benefit from hormone therapy

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 […]

Vulnerable populations more likely to develop chronic pain

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 […]

Common HIV Drugs May Help Prevent Leading Cause of Vision Loss

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 […]

Immune system T cells to be trained to remove cancer

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 […]

‘Five-minute rule’ holds true for cardiac death of organ donors: study

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 […]

Preventing seizures after brain injury could stave off dementia

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 […]

Vaccines safe for majority of immunosuppressed children, find scientists

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; […]

The underestimated mutation potential of retrogenes

A new study from scientists of the Max Planck Institute for Evolutionary Biology in Plön, Germany, and the Chinese Academy of Sciences in Beijing shows that the potential genetic burden of mutations arising from retrogenes is significantly greater than originally thought. Genetic information is stored in DNA and transcribed as […]

Childhood trauma could affect development, treatment of multiple sclerosis, mouse study finds

Childhood trauma could affect the trajectory of multiple sclerosis development and response to treatment in adulthood, a new study in mice found. Mice that had experienced stress when young were more likely to develop the autoimmune disorder and less likely to respond to a common treatment, researchers at the University […]

Suppression of Tyrosine Degradation Modestly Extends Life Span in Flies

There are a great many ways to influence cellular metabolism to modestly slow the pace of aging, but few of them are of lll that much interest from a practical point of view, as a basis for therapies that might meaningfully extend human life spans. If an approach involves improvements […]

Faster tracking of treatment responses

Biological sensors developed by MIT spinout Glympse Bio could help clinicians make decisions for individual patients. In the fight against severe diseases like cancer, patients often endure a discomforting, weekslong gap between when treatment begins and when doctors can tell if it’s working. The problem often stems from an inability […]

Deep Vision: Near-Infrared Imaging and Machine Learning Can Identify Hidden Tumors

Near-infrared hyperspectral imaging combined with machine learning can visualize tumors in deep tissue and covered by a mucosal layer, scientists show Gastrointestinal stromal tumors are tumors of the digestive tract that grow underneath the mucus layer covering our organs. Because they are deep inside the tissue, these “submucosal tumors” are […]
