What factors predict success?

A large-scale study of over 11,000 West Point cadets reveals that both cognitive and non-cognitive factors predict success outcomes. Grit is crucial during Beast Barracks, while cognitive ability is the strongest predictor of academic grades in the classroom. Physical ability also plays a key role in determining graduation rates.

Study of African animals illuminates links between environment, diet and gut microbiome

Researchers analyzed DNA samples from over 1,000 African herbivores to understand the relationship between diet, environment, and gut microbiome. They found that closely related species had similar microbiomes and diets, while domesticated animals like cattle had more sensitive seasonal changes in their microbiomes.

Scientists probe the limits of ice

Researchers found that the transition between ice and water breaks down at the nanoscale, with clusters oscillating between solid and liquid states. The study provides new insights into the conditions necessary for ice formation and has implications for understanding climate regulation and life viability.

Researchers lift the curtain behind the 'black box' of data broker records

A study by INFORMS journal Marketing Science found that data records used in targeted advertising are not as reliable as assumed, with accuracy rates varying between demographics and interests. The researchers conducted field tests to assess the effectiveness of third-party consumer profiling and found mixed results.

Protein Data Bank at Rutgers Awarded $34.5 million grant

The Protein Data Bank at Rutgers has received a $34.5 million grant over five years to enhance services and improve the quality of its vast repository of 3D biomolecular structures. With more than 150,000 structures available, the data bank plays a crucial role in discovering lifesaving drugs and supporting various fields of research.

Tethered chem combos could revolutionize artificial photosynthesis

Scientists at Brookhaven National Laboratory have developed a new approach to artificial photosynthesis that improves the efficiency of capturing light and splitting water molecules to produce hydrogen fuel. The system uses molecular tethers to attach chromophores to catalysts, allowing for stable and efficient electron transfer and ge...

Peering into a more 'human' petri dish

Cell culture media has remained relatively unchanged for over 70 years, but Jason Cantor is developing 'physiologic media' that closely mimics real biological conditions. This allows researchers to study cell behavior in a more accurate and relevant way, potentially revealing fundamental insights into human diseases such as blood cancer.

Health care provider deserts may leave patients in the cold

Researchers found that people with ACA health insurance are more likely to find themselves in 'artificial provider deserts,' areas with limited coverage, and must travel further to access care. The study highlights the need for consumers to carefully consider their insurance options to make informed decisions about their healthcare.
