Technology allowing different concentrations of drugs and chemicals on various parts of same tissue shows promise

A new technology developed by Purdue University researchers allows different concentrations of a drug or a chemical to be targeted at different areas of the same cancerous tissue in the laboratory. The discovery may help the more than 1.7 million people the National Cancer Institute predicts will be diagnosed with […]

Potent bacteria

A special strain of soil bacteria has the paradoxical ability to produce highly toxic compounds to protect itself from other organisms without harming itself. A collaboration that includes scientists from the Department of Energy’s (DOE) Argonne National Laboratory has discovered that the bacteria performs this feat by confining the toxic […]

Epigenetic patterns determine if honeybee larvae become queens or workers

Queen and worker honeybees are almost genetically identical but are fed a different diet as larvae. The researchers have found that specific protein patterns on their genome play an important role in determining which one they develop into. These proteins, known as histones, act as switches that control how the […]

Female Mice are Immune to Cognitive Damage from Space Radiation

Humankind still dreams of breaking from the bounds of Earth’s atmosphere and venturing to the moon, Mars and beyond. But once astronauts blast past the International Space Station, they become exposed to one of the many dangers of deep space: galactic cosmic radiation. The effects of deep space radiation are […]

Twin study highlights importance of both genetics and environment on gene activity

New research highlights the extent to which epigenetic variation is influenced by both inherited and environmental factors. Epigenetic processes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome. Now, an […]

Researchers propose new theory of aging

A high-energy molecule present in every cell, adenosine triphosphate (ATP), is the form of stored energy used to accomplish much of a cell’s activities. A new theory of aging published in the journal BioEssays addresses the link between ATP levels and aging, based on broad research showing that stored energy levels decrease […]

A depressed spouse may increase one’s own cognitive decline, study finds

Researchers at Yale School of Public Health and their scientific partners have found that having a depressed spouse can increase one’s own depressive symptoms as well as cognitive decline over time in late life. The findings are published in the American Journal of Geriatric Psychiatry. “Because spouses’ emotions and intellectual activities […]

Both High and Low Carbohydrate Diets Reduce Lifespan in Humans

According to a new prospective cohort study and meta-analysis, published 16 August 2018 in the journal The Lancet Public Health, advocates of both very high and very low carbohydrate diets are wrong about which approach is best for health. The aim of the paper was to assess “whether the substitution […]

First study on physical properties of giant cancer cells may inform new treatments

Polyploidal cancer cells—cells that have more than two copies of each chromosome—are much larger than most other cancer cells, are resistant to chemotherapy and radiation treatments and are associated with disease relapse. A new study by Brown University researchers is the first to reveal key physical properties of these “giant” cancer cells. […]

Byproducts of ‘Junk DNA’ Implicated in Cancer Spread

The more scientists explore so-called “junk” DNA, the less the label seems to fit. Only an estimated two percent of the human genome encodes for functional proteins that carry out normal biological processes. The remaining approximately 98 percent—the “junk DNA”—has for many years been considered a useless artifact. Some junk […]

Parental Life Span Predicts Daughters Living to 90 without Chronic Disease or Disability

Researchers at the University of California San Diego School of Medicine report that women whose mothers lived to at least age 90 were more likely to also live to 90, free of serious diseases and disabilities. The study, published in Age and Ageing, found women whose mothers lived into their ninth […]

Tasmanian devils under new threat from cancer, Southampton research finds

A new study has shown that the Tasmanian devil is under severe threat from a newly emerged contagious cancer, Devil Facial Tumour 2 (DFT2), which could jeopardise its future in the wild. For more than two decades the Tasmanian devil population has been suffering from Devil Facial Tumour Disease (DFTD), […]

Older adults who get physical can lower their heart disease risk

The results from increased physical activity were found to be particularly good among women. Physical inactivity is a well-known risk factor for cardiovascular disease and premature death from cardiovascular disease. Physical activity’s protective effect is likely due in part to its impact on biomarkers in the blood that help predict atherosclerosis risk. “The 60 […]

This Matrix Delivers Healing Stem Cells to Injured Elderly Muscles

A car accident leaves an aging patient with severe muscle injuries that won’t heal. Treatment with muscle stem cells from a donor might restore damaged tissue, but doctors are unable to deliver them effectively. A new method may help change this. Researchers at the Georgia Institute of Technology engineered a molecular matrix, […]

Common skin cancer can signal increased risk of other cancers

People who develop abnormally frequent cases of a skin cancer known as basal cell carcinoma appear to be at significantly increased risk for the development of other cancers, including blood, breast, colon and prostate cancers, according to a preliminary study by researchers at the Stanford University School of Medicine. The increased […]

Father’s genes can impact motherly love

The team of researchers from Cardiff University’s School of Biosciences investigated the hormonal signals given off from the placenta during pregnancy. The placenta transports nutrients to the growing foetus during pregnancy and gives off hormonal signals in the mother’s bloodstream to establish and maintain a successful pregnancy. As well as […]

Lessons from flies: genetic diversity impacts disease severity

New research offers clues as to why some diseases are highly variable between individuals. The phenomenon is apparent in people with retinitis pigmentosa, a condition that causes the light-sensing cells in the eye to degenerate. While some only develop night blindness, others completely lose their sight, even when their condition […]

From ‘sea of mutations,’ two possible cancer links rise to the surface

Many genetic malfunctions are commonly found in cancers, and scientists are working to distinguish those directly involved in both the initial growth of cancer and its spread throughout the body. The complexity of both the disease and the ordinary functions of the genome have made this a difficult problem. However, […]

Eye conditions provide new lens for screening for Alzheimer’s

Alzheimer’s disease is difficult to diagnose as well as treat,  but researchers now have a promising new screening tool using the window to the brain:  the eye. A study of 3,877 randomly selected patients found a significant link between three degenerative eye diseases – age-related macular degeneration, diabetic retinopathy and glaucoma – […]

Double time limit for embryo research to further research into IVF, synthetic embryos and gene editing

In countries which already permit embryo research, there are no “compelling moral arguments” why the time limit for experimentation should not be doubled say ethics experts. Currently, research on embryos is limited in many countries to a maximum period of 14 days after their fertilisation in the lab. But ethicists […]

Soy diets might increase women’s bone strength

Osteoporosis, decreased physical activity and weight gain are serious health concerns for postmenopausal women. Researchers from the University of Missouri now have discovered through a new animal study that soy protein found in food might counter the negative effects of menopause on bone and metabolic health. Moreover, the researchers believe that soy […]
