Dietary Adherence and the Fight Against Obesity

While eating less and moving more are the basics of weight control and obesity treatment, finding ways to help people adhere to a weight-loss regimen is more complicated. Understanding what features make a diet easier or more challenging to follow can help optimize and tailor dietary approaches for obesity treatment. […]

Study finds high potential for developing dementia for agricultural workers

A University of Iowa study finds people who work long-term in the agricultural industry have 46% greater odds of developing dementia than those in other fields. Professor Kanika Arora in the U-I College of Public Health, says hearing impairment, depression and isolation can all be linked to dementia and to […]

Researchers find link between children’s time perception and risk for developmental coordination disorder

Neuroscientists at McMaster University have found a link between children who are at risk for developmental coordination disorder (DCD), a common condition that can cause clumsiness, and difficulties with time perception such as interpreting changes in rhythmic beats. Accurate time perception is crucial for basic skills such as walking and […]

Artificial Intelligence can help diagnosing depression and psychosis

Artificial intelligence is going to become a great diagnostics tool in medicine. It can notice details in images that go unnoticed for a human eye. However, up until now it was almost impossible to imagine AI being used to diagnose mental conditions. Now scientists at the University of Birmingham have […]

Air pollution linked to poor thinking skills later in life

One of the worst problems of our times is air pollution. Our transport and industries produce poisonous gases that all people, especially the ones in the city, have to breathe. Of course it is not healthy – scientists have found associations between air pollution and all kinds of diseases, including […]

Probiotics or prebiotics? Exploring the complex world of ‘gut’ health

University of Missouri researchers develop a noninvasive way for identifying the major functions of the gastrointestinal tract. A healthy person has a general balance of good and bad bacteria. But that balance is thrown off when someone gets sick. So, to help boost their levels of good bacteria, many people […]

‘Hidden Biological Link’ Among Autism Genes Revealed in Study

Powerful Frog-Embryo Model Unveils New Role for Risk Genes, Protective Effect of Estrogen. A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis – a process in which specialized “progenitor” cells give rise to new brain cells – in the […]

Compound isolated from human sperm could treat genetic disorder

A newly discovered genetic condition caused by faulty protein synthesis which causes delayed development and learning difficulties could be treated by a compound originally isolated from human sperm, say, scientists. The University of Manchester researchers, with collaborators from the UK, France and US, identified rare changes in a gene called […]

Cell Bones Mystery Solved with Supercomputers

Our cells are filled with ‘bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, actin filaments constantly grow, shrink, bind with other things, and branch off […]

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 […]

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 […]

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 […]

Today's Stem Cell Special: Small Intestine on a Plate!

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 […]

Study finds childhood diet has lifelong impact

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 […]

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 […]

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 […]
