Repeated eye injections for age-related macular degeneration associated with increased risk for glaucoma

A study published in JAMA Ophthalmology found that patients with age-related macular degeneration who received seven or more eye injections of bevacizumab annually had a higher risk of developing moderate to advanced glaucoma. This increased risk was associated with the potential for elevated intraocular pressure, highlighting the need...

New anti-Wolbachia drug regimen could reduce treatment times of LF and Oncho to 1-2 weeks

Scientists have developed a shorter treatment regimen using rifampicin to target Wolbachia, reducing treatment times for lymphatic filariasis (LF) and onchocerciasis (Oncho) to just 1-2 weeks. This regimen is safe for pregnant women and children, offering a more effective and accessible solution to these debilitating diseases.

58 million Americans are exposed to loud, frequent noises, including firearms, at work and home

A recent study published in The Laryngoscope found that substantial noise exposures occur in occupational and recreational settings, with only a small percentage of those exposed wearing recommended hearing protection. Firearms use is a significant contributor to noise exposure, with only 58% of gun owners using hearing protection.

Immune cell drives heart failure in mice

Researchers found that eosinophils play a key role in the progression of heart muscle inflammation to heart failure in mice. The study suggests that eosinophils may be responsible for the deterioration of heart muscle function, even in the absence of severe inflammation.

Agriculture, dietary changes, and adaptations in fat metabolism from ancient to modern Europeans

A study on European populations reveals genetic adaptations to dietary changes, influencing the production of vital fatty acids. The findings suggest that Europeans are adapting to a diet rich in plant-derived fats, while those with high animal fat intake produce more long-chain PUFAs.

Novel nozzle saves crystals

Scientists developed a novel double flow-focusing nozzle to reduce protein crystal consumption in X-ray crystallography. The new device enables stable experimental conditions, increases the rate of high-quality diffraction patterns, and widens the spectrum of biomolecules that can be analysed.

Climate had a hand in shaping the human nose

A study published in PLOS Genetics found that nose size and shape are linked to differences in ancestral temperature and humidity levels. Wider nostrils were correlated with ancestors who lived in warmer climates, suggesting a role for climate in shaping human nasal evolution.

Not like the other black girls

A study by Colleen Butler-Sweet found that young middle-class black women experience tension with poorer black women, feeling like 'stepsisters' due to social class differences. These women often face criticism and pressure to conform to white beauty standards, exacerbating feelings of alienation and competition.

The fed's bank bailout

New research from Washington University in St. Louis shows that the Fed's actions were effective in encouraging banks to lend, benefiting the economy. The study found that a total of 62% of bigger US banks used the Discount Window or Term Auction Facility during the crisis, leading to increased lending of almost all types.

Nose form was shaped by climate

The study found that nose width is strongly correlated with temperature and humidity levels in different climates, suggesting a role for natural selection in shaping nose shape. The researchers also identified differences between men and women in nose features across populations.
