MRI technique induces strong, enduring visual association

MRI technique induces strong, enduring visual association

PROVIDENCE, R.I. [Brown University] -- Researchers have made two new scientific points with a set of experiments in which they induced people to perceive colors that weren't really there -- one concerning how the brain works and the other concerning how to work the brain.

Working with colleagues in Japan, the scientists at Brown University used a novel technique to surreptitiously train a small group of volunteers to associate vertical stripes with the color red and -- to a lesser extent as a consequence -- horizontal stripes with the color green.

In making tough decisions, plants weigh the risks

In making tough decisions, plants weigh the risks

In making tough, life-changing decisions, people often weigh the risks associated with the options before them and choose accordingly. Now researchers reporting in the Cell Press journal Current Biology on June 30 have found that pea plants also make choices about how to grow based on an assessment of risk.

Towards a cure for herpesviruses: Targeting infection with CRISPR/Cas9

Towards a cure for herpesviruses: Targeting infection with CRISPR/Cas9

Most adults carry multiple herpesviruses. Following the initial acute infection, these viruses establish life-long infections in their hosts and cause cold sores, keratitis, genital herpes, shingles, infectious mononucleosis, and other diseases. Some herpesviruses can cause cancer in man. During the latent phase of infection, the viruses remain dormant for long periods of time, but retain the capacity to cause occasional reactivations, that may lead to disease.

A quick and easy new method to detect Wolbachia bacteria in intact Aedes mosquitoes

A quick and easy new method to detect Wolbachia bacteria in intact Aedes mosquitoes

Aedes aegypti mosquitoes transmit dengue, chikungunya, and zika viruses. A study published in PLOS NTDs reports a new technique that could make one approach to mosquito control--using Wolbachia bacteria that reduce the mosquitos' ability to transmit viral pathogens--a whole lot easier and cheaper to implement and evaluate.

Surprising number of businesses selling unapproved stem cell 'treatments' in the US

Surprising number of businesses selling unapproved stem cell 'treatments' in the US

At least 351 companies across the United States are marketing unapproved stem cell procedures at 570 individual clinics. Such businesses advertise "stem cell" interventions for orthopedic injuries, neurological disorders, cardiac diseases, immunological conditions, pulmonary disorders, injured spinal cords, and cosmetic indications.

Harnessing an innate repair mechanism enhances the success of retinal transplantation

Harnessing an innate repair mechanism enhances the success of retinal transplantation

Regenerative therapies, based on cell replacement, hold promise for a wide range of age-related diseases, but efforts to bring the therapies to patients have not been very successful - in large part because the newly-derived replacement cells can't integrate efficiently into tissues affected by the ravages of aging. Publishing in Science, researchers at the Buck Institute harnessed a naturally-occurring and evolutionarily ancient anti-inflammatory mechanism that repaired the eye and significantly enhanced the success of retinal regenerative therapies in mice.

New therapy treats autoimmune disease without harming normal immunity

New therapy treats autoimmune disease without harming normal immunity

PHILADELPHIA--In a study with potentially major implications for the future treatment of autoimmunity and related conditions, scientists from the Perelman School of Medicine at the University of Pennsylvania have found a way to remove the subset of antibody-making cells that cause an autoimmune disease, without harming the rest of the immune system. The autoimmune disease the team studied is called pemphigus vulgaris (PV), a condition in which a patient's own immune cells attack a protein called desmoglein-3 (Dsg3) that normally adheres skin cells.

Air pollution linked to increased rates of kidney disease

Highlights

  • The likelihood of developing membranous nephropathy, an immune disorder of the kidneys that can lead to kidney failure, increased 13% annually over 11 years in China.

  • Regions with high levels of fine particulate air pollution had the highest rates of membranous nephropathy.

Fukushima and the oceans: What do we know, 5 years on?

A major international review of the state of the oceans 5 years after the Fukushima disaster shows that radiation levels are decreasing rapidly except in the harbour area close to the nuclear plant itself where ongoing releases remain a concern. At the same time, the review's lead author expresses concern at the lack of ongoing support to continue the radiation assessment, which he says is vital to understand how the risks are changing.

Study finds potential treatment for non-alcoholic fatty liver disease

CINCINNATI - Researchers report in the journal Cell Reports a targeted molecular therapy that dramatically reduces the initial development of Non Alcoholic Fatty Liver Disease (NAFLD) in laboratory mouse models of the disease.
