CRISPR treats genetic disorder in adult mammal

Duke University researchers successfully treated an adult mouse model of Duchenne muscular dystrophy using CRISPR gene editing. The treatment involved delivering the gene-editing system directly to the affected tissues through a non-pathogenic carrier called adeno-associated virus, overcoming several delivery challenges.

Penn-led team reprograms social behavior in carpenter ants using epigenetic drugs

A Penn-led team has discovered that caste-specific behaviors in ant colonies can be directly altered by changing the balance of epigenetic chemicals. The study found that compounds inhibiting histone acetylation increased foraging behavior in minors, while injecting these inhibitors into young major ants also boosted foraging activity.

Seeing DROSHA for the first time

Scientists at IBS Center for RNA Research have elucidated the three-dimensional image of DROSHA, one part of the Microprocessor complex. This discovery confirms previous findings and reveals unique physical characteristics of DROSHA, including a 'bump' that may act as a measuring guide for cleaving pri-miRNA.

Virtual colonoscopy an alternative to FOB test & colonoscopy for colorectal cancer?

A study published in JNCI Journal of the National Cancer Institute found that virtual colonoscopy had higher detection rates than traditional methods like FIT and OC. The researchers concluded that combination of lower attendance and higher detection rate makes CTC a key factor for optimization of its role in population screening.

Research finds parents can play a role in preventing teen fighting

A study by LA BioMed suggests that involving parents in violence prevention programs and tailoring them to specific racial/ethnic groups can improve their effectiveness. The research found that Latino parents condoned fighting only as a last resort, while African American parents sometimes saw it as necessary.

Let hunger be your guide

Research found that eating moderately hungry reduces blood glucose levels after meals, whereas eating when not hungry may be detrimental to health. This study suggests that individuals should listen to their hunger cues and eat when they're truly hungry rather than relying on convenience foods.

Extinguishing thirdhand smoke

Thirdhand smoke is a persistent and hazardous environmental contaminant left behind by smoking. Researchers at San Diego State University are studying its spread and effects on human health, with a focus on vulnerable populations like young children and those with compromised immune systems. The team has found links between thirdhand s...

Factors predicting low patient accrual in cancer clinical trials

A study analyzed 787 phase II/III clinical trials sponsored by the National Clinical Trials Network, finding that increased competition, planning to enroll a larger proportion of the available population, and lack of new agents were associated with poor accrual. The researchers developed a multivariable prediction model to identify tri...

Temple study finds opioid prescribing guideline significantly decreases prescription rates

A Temple University study found that an opioid prescribing guideline significantly decreased prescription rates for minor conditions and chronic noncancer pain in acute care settings. The guideline was implemented in January 2013 and resulted in a high degree of statistical significance across all age groups and complaint categories.

Plain packaging effective in reducing misperceptions of tobacco products among Australian Indigenous

A study found that plain packaging decreased overall perceptions of healthier tobacco brands by 12%, as well as reduced prestige perceptions among young Indigenous smokers. The findings support the effectiveness of health warnings in reducing global tobacco use, particularly among vulnerable populations.

Thermal microscopy of single cells

A team of researchers developed a new imaging approach that provides images of a single cell with micrometer resolution using a contrast based on the cell's thermal properties. This technique allows for unprecedented sensitivity in detecting diseased conditions at the sub-cell scale and may aid in optimizing cryopreservation processes.
