Percolating a solution to hexavalent chromium

Researchers found that coffee husks can adsorb almost 50 milligrams of hexavalent chromium per gram, with two-thirds of the absorbed chromium recoverable. The use of coffee husks presents a viable and cost-effective part of a waste-management strategy due to their availability, safety in storage, and lack of protein.

Medical researchers break down costs to care for heart failure patients at the end of life

Researchers found that majority of heart failure patients pass away in acute care hospital, resulting in significantly higher costs. The study examined data from over 30,000 elderly patients with heart failure who died between 2000 and 2006 in Alberta, highlighting the need for discussions about end-of-life care options.

Brain imaging identifies differences in childhood bipolar disorder, ADHD

Researchers identified distinct brain network abnormalities in children with pediatric bipolar disorder (PBD) and attention deficit hyperactivity disorder (ADHD), with the ADHD group showing more severe dysfunction in working memory circuits. The study suggests that better differentiation between the two disorders could lead to more ac...

Lose the weight, not the potatoes

A 12-week study of 86 overweight participants found that all three groups lost weight when consuming five to seven servings of potatoes per week. The results suggest that potatoes, when prepared in a healthy manner, do not contribute to weight gain and can be part of a weight loss program.

Getting out of the house after stroke

Researchers are conducting a national study to assess whether a targeted rehabilitation approach can aid stroke patients in leaving their homes more confidently. The study will compare outcomes of volunteer patients receiving the intervention with those not receiving it, aiming to improve physical capabilities and boost confidence.

Diagnosing autism with MRI is 1 step closer

Researchers at the University of Utah Health used MRI to identify areas where the left and right hemispheres of the brains of people with autism do not properly communicate. The study found functional connectivity abnormalities in the entire brain, adding to the understanding of this disorder.

Gambling on bacteria

Research by Prof. Eshel Ben-Jacob suggests that bacteria can effectively control 'noise' in their environment and make decisions that benefit the entire colony. Bacteria's group decision-making processes can inform human decision-making, particularly in situations with multiple stakeholders.

Being more realistic about the public health impact of genomic medicine

Researchers argue that genomic risk prediction for population-level preventive healthcare is not yet supported by evidence. A cost-effective approach would require interventions for those at risk, but such an approach has yet to be demonstrated. The authors caution against widescale implementation of genetic screening for disease risk.

Landing lights for bumblebees

Growing plants with red flowers or striped blooms can significantly increase the number of visits from bumblebees, according to a study by Norwich BioScience Institutes. The research found that stripes following the veins of flowers provide a visual guide for pollinators, directing them to nectar and pollen.
