Electron cryo-microscopy: Using inexpensive technology to produce high-resolution images

Researchers at Martin-Luther-University Halle-Wittenberg have successfully determined the structure of ferritin using an affordable electron cryo-microscope, achieving resolutions comparable to expensive equipment. This method enables collaboration on structural analysis of samples with medical and biotechnological potential.

Jumping course

Scientists have discovered three ways that deltas can respond to sea level rise, depending on the balance between sediment supply and rate of sea-level change. This understanding has significant implications for climate change and human interference, with potential impacts on river ecosystems and societal stability.

University research and the private sector

A University of Illinois study using neonatal pigs found that pectin at 0.2% in milk replacer was safe for infants, a breakthrough made possible by public-private partnerships. The research highlights the benefits of collaborations between universities and industry, enabling faster innovation and high-quality science.

Childhood maltreatment may be linked to heart disease in adulthood

Research published in the journal Heart found that adults who experienced childhood maltreatment are at a higher risk of cardiovascular disease, with women being particularly vulnerable. The study analyzed data from 157,311 participants and found associations between all types of maltreatment and increased risk of CVD in both sexes.

Examine narratives to end policy deadlock, boost agricultural development in Africa, economists say

Researchers argue that one-sided narratives shape the dichotomy between state-led and market-led approaches to promote agricultural development. A combination of state-led initiatives, donor-funded or market-led approaches, and input subsidy programs can work if there is evidence-based policy learning between both camps.

Green is more than skin-deep for hundreds of frog species

Hundreds of frog species have a green coloration due to a biochemical workaround that combines a virus-fighting protein with a toxic bile pigment, not relying on traditional skin chromatophores. This adaptation ensures good camouflage in leafy environments and has evolved over 40 times across different families of treefrogs.

More lonely deaths in hospitals and nursing homes from COVID

A Northwestern University study found that COVID-19 patients are 12 times more likely to die in a medical facility than patients who died from any cause in 2018. The high rate of deaths in hospitals and nursing homes highlights the need for improved end-of-life care, including access to virtual communication with families.

Severely damaged human lungs can now be successfully recovered

A multidisciplinary team from Columbia Engineering and Vanderbilt University has successfully recovered severely injured donor lungs using a cross-circulation platform. This method provides intrinsic biological repair mechanisms over long periods, enabling the recovery of lungs that cannot be saved by standard clinical EVLP.

Consumer-created social media visuals capture consumer brand perceptions

Consumer-created social media visuals are reflective of consumer brand perceptions, according to researchers who developed a new model called BrandImageNet. This model maps images to perceptual attributes of a brand, allowing firms to automatically monitor consumers' brand perceptions and evaluate their positioning strategies.

Study shows humans are optimists for most of life

Researchers found that people tend to become more optimistic as they age, with a significant increase during young adulthood. Despite major life events, such as divorce or illness, people generally remain positive about their future, finding ways to maintain emotional balance and focus on happiness.
