On Facebook ads, users may dislike ‘likes’

A new study from Texas McCombs finds that accumulating 'likes' can lead to fewer clicks for assertive CTA ads, but more clicks for informational ads. The researchers discovered that users respond positively to 'likes' from friends with similar interests, while those with dissimilar interests have a negative effect.

Scientists discover how the body's killer cells attack cancer

Researchers have found that natural killer cells instinctively recognize and attack the XPO1 protein, which drives cancer growth. By targeting this protein, scientists may be able to activate more killer cells to destroy cancer cells. The study suggests that this approach could lead to personalized cancer treatment with less side effects.

How breast cancer goes hungry

Researchers at Cold Spring Harbor Laboratory have discovered a strategy to kill breast cancer cells and shrink tumors by depriving them of two vital nutrients: glutamine and its backup supply, alpha-ketoglutarate. This approach was successful in lab experiments and effective in treating tumors in mice.

‘Silent’ mutations found to have repercussions beyond their own gene

Silent gene mutations may have significant consequences beyond their own gene, according to a study published in the Proceedings of the National Academy of Sciences. Researchers found that synonymous mutations in one gene can increase the production of a neighboring gene by recruiting RNA polymerase to cryptic transcription sites.

People experiencing relatively mild cases of mental ill-health may be perceived differently by others depending on whether or not diagnostic labels are provided

Research suggests that diagnostic labels for people experiencing mild mental health issues can increase empathy and support, but also undermine perceived agency and expectations of overcoming problems. This study found varying responses depending on the disorder, with some conditions eliciting high empathy and accommodation support.

TILDA reveals crucial insights on loneliness and death ideation among older adults

A study of 8,000 community-dwelling adults reveals that loneliness in later life is strongly associated with death ideation, but engaging in social activities, particularly religious services, can protect against this. The research highlights the critical issue of social disconnection and its link to a 'wish to die' among older adults.
