A novel concept for a biosensor of the metabolite known as lactate, combines an electron transporting polymer with lactate oxidase, which is the enzyme that specifically catalyzes the oxidation of lactate. Lactate is associated with critical medical conditions so its detection is important for healthcare.

An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases.

Scientists have solved the riddle behind one of the most recognisable, and annoying, household sounds: the dripping tap. And crucially, they have also identified a simple solution to stop it, which most of us already have in our kitchens.

Princeton chemists have found a way to make a naturally occurring enzyme take on a new, artificial role, which has significant implications for modern chemistry, including pharmaceutical production. Their work appears in the journal Nature Chemistry.

A new web-based "feedback" technology which allows therapists to accurately monitor how patients with depression are coping has been found to reduce the probability of deterioration during psychological treatment by 74%, a new study has found.

The study, which is the largest controlled trial of its kind, involved data from more than 2,000 mental health patients treated across multiple NHS Trusts in England.

PHILADELPHIA -- Black Americans are nearly three times more likely to be killed by police than their white counterparts, with even larger disparities among those who are unarmed. The trend is also harming the mental health of the black community, according to new research published in The Lancet from the Perelman School of Medicine at the University of Pennsylvania and the Boston University School of Public Health.

TORONTO, June 21, 2018--A preference for male children persists among second-generation mothers of South Asian descent, according to new study that found a skewed ratio of male-to-female babies born to these women in Ontario.

The findings, published today in the Journal of Epidemiology and Community Health, came from the same group of researchers who reported in 2016 that more male babies than expected were being born to Indian-born women living in Canada.

BIRMINGHAM, Ala. - A surprising form of cell-to-cell communication in glioblastoma promotes global changes in recipient cells, including aggressiveness, motility, and resistance to radiation or chemotherapy.

Paradoxically, the sending cells in this signaling are glioblastoma cells that are undergoing programmed cell death, or apoptosis, according to research by a team at institutes in the United States, Russia and South Korea.

New Rochelle, NY, June 20, 2018--Tissue-engineered articular cartilage (AC) for repairing cartilage damaged by trauma or disease can be made to more closely mimic natural AC if mechanical stimulation of particular magnitude and duration is applied during the development process.

The UK's first energy-positive classroom, designed with research expertise from Swansea University, generated more than one and a half times the energy it consumed, according to data from its first year of operation, the team has revealed.

The findings were announced as the researchers launched the next phase of their research, gathering data and evidence on an office building, constructed using similar methods.
