Sainsbury's is trialling new food-cooling technologies that promise to be more eco-friendly than current alternatives.

Exercise that puts greater strain on bones, like running, may improve long-term bone health more effectively than non weight-bearing activities like cycling, conclude the authors of a new study measuring the hormones of mountain ultra-marathon runners.
Chemicals commonly found in plastics and fungicides may be weakening children’s teeth by disrupting hormones that stimulate the growth of dental enamel, according to a new study.
Male-to-female (MtF) transgender persons have a greater increase in bone mineral density than female-to-male (FtM) persons in their first year of hormone treatment. The research helps scientists further understand the roles sex hormones play on bone development and maintenance in both sexes.
Children with a strong family history of cardiovascular disease and/or type 2 diabetes were found to have cholesterol levels significantly higher than children with no family history of those conditions, new research shows.
New research uncovers the action mechanism of an enzyme called DHHC9 in normal development and function of neural networks in the brain. Mutations in DHHC9 have been identified in patients suffering from X-linked Intellectual Disability. The work shows DHHC9 plays a vital role in promoting the growth and branching of neurons and in maintaining the balance between excitatory and inhibitory signals being formed onto neurons.

The use of next-generation gene sequencing in newborns in neonatal intensive care units (NICUs) may improve the diagnosis of rare diseases and deliver results more quickly to anxious families, according to new research in CMAJ (Canadian Medical Association Journal).

Early exposure to nicotine can trigger widespread genetic changes that affect formation of connections between brain cells long after birth, a new Yale-led study has found. The finding helps explains why maternal smoking has been linked to behavioral changes such as attention deficit and hyperactivity disorder, addiction and conduct disorder.

Scientists at the University of Birmingham are a step closer to understanding the role of the gene BRCA1. Changes in this gene are associated with a high risk of developing breast and ovarian cancer.

Just as members of an orchestra need a conductor to stay on tempo, neurons in the brain need well-timed waves of activity to organize memories across time. In the hippocampus--the brain's memory center--temporal ordering of the neural code is important for building a mental map of where you've been, where you are, and where you are going. Published on May 30 in Nature Neuroscience, research from the RIKEN Brain Science Institute in Japan has pinpointed how the neurons that represent space in mice stay in time.


Tailor-made ratiometric sensors make baker's yeast cells light up green, as Georgia Tech scientists use it to track the movements of the essential toxin heme.
A pinch of poison is good for a body, at least if it's heme.
