Visual imagery technique boosts voting, study finds

A new study found that using a visual imagery technique, specifically picturing oneself as an outsider, can significantly boost voter turnout. The technique, which involves viewing oneself from a third-person perspective, increased voter participation rates by up to 90%, compared to those who took a first-person viewpoint.

How Rett Syndrome mutation targets the brain

Researchers identified a key mechanism behind Rett Syndrome by pinpointing the S421 site on the MeCP2 protein responsible for its normal function. This specificity explains why mutations affecting that site target brain development, leading to delays in motor skills and speech loss.

The smell of iron

Researchers discover that iron exposure causes a distinct metallic smell in humans, linked to skin oil and blood decomposition. The key compound responsible for this 'metallic' odor is identified as 1-octen-2-one, produced when oils on skin are oxidized by certain enzymes.

Color names: More universal than you might think

Researchers found that people from preindustrial societies consistently classify colors into eight categories: red, green, yellow-or-orange, blue, purple, brown, pink, and grue. The study used data from the World Color Survey to analyze color names across 110 languages, revealing a universal framework for color perception.

Intrinsic eye protein halts angiogenesis

Scientists identified SFLT-1 as the protein responsible for preventing blood vessel growth in corneas. Deactivating this protein allows angiogenesis to occur, leading to conditions such as macular degeneration and cancer. The discovery opens doors to new treatments by harnessing the natural anti-angiogenic properties of the eye.

Liverpool to be global cancer research hub

The University of Liverpool, Royal Liverpool University Hospital and Clatterbridge Centre for Oncology are merging to create a cancer research centre, enabling global clinical trials of new therapies. The centre will be funded by Cancer Research UK and will double the number of patients in early phase clinical trials.

Cigarette smoking impedes tendon-to-bone healing

Researchers found that nicotine delays tendon-to-bone healing, reducing cellular proliferation and collagen production. This can lead to weaker tissue and increased vulnerability to re-injury after surgery. The study used a rat shoulder model to investigate the effects of cigarette smoking on rotator cuff repair.
