Study Shows Glucose Consumption Increases Production of Destructive Free Radicals, Lowers Level of Key Antioxidant

A study published in The Journal of Clinical Endocrinology and Metabolism found that excess glucose consumption stimulates the generation of free radicals, which can damage cells lining blood vessels. The researchers also observed a decrease in levels of a-tocopherol, a powerful antioxidant.

Some autistic people have memory advantage for certain tasks

Researchers found that individuals with autism spectrum disorder (ASD) performed better on a 'false-memory' test due to their impaired ability to use context. This improvement enabled them to recognize words that had been on a word list, while non-autistic subjects struggled with false memories. The study suggests that high-functioning...

Aging alters sleep and hormone levels sooner than expected

Researchers found two stages of age-related deterioration of sleep quality: the first between young adulthood (16-25) and mid-life (35-50), and the second after age 50. Changes in sleep quality were mirrored by changes in hormone secretion, particularly growth hormone, which declined significantly with age.

Rice research another step forward for green revolution

A new system of planting different varieties of rice plants can significantly reduce problems with the fungal disease 'blast', which causes lesions on rice plants, reduces yields and in severe cases can kill entire crops. This approach has been shown to eliminate losses to blast in some types of glutinous rice.

Man longs for purity

A study by Prof. Arnold Labrie explores how desire for purity emerged as a response to societal changes, masking a preoccupation with the impure. The concept of purity is closely tied to order and excludes those deemed 'impure', reflecting underlying tensions between traditional values and emerging modernities.

Brown physicist proposes that electron may be split

Electrons may undergo fission in liquid helium at temperatures near absolute zero, violating the long-held notion that elementary particles cannot be broken into two pieces. Experimental evidence supports this theory, which suggests that light can cause an electron's bubble to divide into smaller bubbles.

Scarce evidence that chronic pain treatments work

A recent survey in the Netherlands reveals that chronic pain affects approximately 18% of the population, with frequent problems including lower back pain and abdominal pain. The study highlights the need for more research into the effects of treatment methods, as current evidence is often inadequate or contradictory.

Insult laws threaten press freedom, new UNC-CH global research shows

A new study reveals that over 100 countries have laws that can imprison journalists for 'insulting' government officials and institutions. The World Press Freedom Committee sponsored the research, led by Dr. Ruth Walden, which found that such laws undermine democracies and stifle free speech.
