Cataract culprits

University of Delaware researchers have identified two genes linked to cataract formation. Deficiency in these genes leads to lens clouding and cataract development without aging or radiation exposure required. The study could contribute to interventions that delay or prevent cataract formation.

UPitt researchers find link between neighborhood quality and cellular aging

A study by University of Pittsburgh researchers found a significant link between living in neighborhoods with high crime and vandalism and biological aging processes. Telomere length, a key indicator of cellular health, was found to be shorter in individuals from disadvantaged areas, similar to a 12-year chronological age difference.

What can 3-year-olds teach us about justice? Plenty

Researchers found that young children prefer to return lost items to their rightful owners and prevent a third party from taking what doesn't belong to them. This suggests that a concern for others is a core component of a sense of justice, likely central to human cooperation.

Lefties are all right with kangaroos

Wild kangaroos show a consistent preference for using their left hands for actions like grooming and picking leaves. The finding expands our understanding of handedness in animals and may offer insights into neuropsychiatric conditions such as schizophrenia and autism.

A better way to build bones

Researchers at NYU Polytechnic School of Engineering and NYU School of Medicine are exploring a new method to amplify the body's signaling system for recruiting bone-forming stem cells to injured areas. They plan to focus on a single recruitment factor, CXCL12, which they hypothesize plays key roles in promoting osteogenesis.

Sequencing Ebola's secrets

A global team has sequenced over 200 Ebola virus genomes to capture the fullest picture yet of how the virus is transmitted and changes over time. The study reveals that cross-border transmission played a smaller role in the outbreak than previously thought, and that the virus has begun to weed out mutations that do not benefit it.

Safeguarding against chlamydia

A new vaccine has been developed that generates double protection against chlamydia by teaching the immune system to recognize and remember the bacteria as a threat. The vaccine uses charge-switching synthetic adjuvant nanoparticles to bind to the bacteria, targeting mucosal surfaces and inducing an immune response.

Jet contrails affect surface temperatures

Researchers found that jet contrails depress daytime-highs and nighttime-lows, mimicking the effect of ordinary clouds, with a 5-6 degree Fahrenheit reduction in daily temperature range in regions like the South and Midwest.

On the road to needle-free medicine

Alternative drug-delivery systems are being explored to overcome syringe injection drawbacks, including ointments, dissolvable tablets and micro-needle skin patches. Several promising results have been shown in animal testing, but widespread adoption will require changing the mindset of pharmaceutical companies and regulators.
