'Democratic peace' may not prevent international conflict

Researchers at Ohio State University challenge the widely-held theory that democracies are less likely to go to war with each other. Their new technique and model accurately predicted international conflict five and ten years in advance, outperforming existing models. The study highlights the importance of economic trade relationships ...

Could more intensive farming practices benefit tropical birds?

A study in the Chocó-Andes of Colombia found that intensive farming practices lead to a loss of more than 650 million years of evolutionary history in bird species. Land-sparing approaches, which protect larger blocks of natural habitat, are recommended as a more effective way to preserve biodiversity.

Babies benefit from parenting classes even before birth

A series of parenting classes, Family Foundations, has been shown to reduce parental stress, depression, and anxiety, while improving parenting quality and long-term child outcomes. Participation in the program was linked to more optimal birth weight and shorter hospital stays for mothers at risk.

Increased odds for type 2 diabetes after prenatal exposure to Ukraine famine of 1932-33

Researchers found a strong link between prenatal exposure to the Ukrainian Famine of 1932-33 and an increased risk of type 2 diabetes in adulthood. The study, which included over 43,000 cases of type 2 diabetes, suggests that early gestation is a critical period for the development of long-term health outcomes.

Marine species on the move

A new study by UC Santa Barbara researchers predicts that climate change will cause significant reshuffling of marine biodiversity, with warming oceans leading to the relocation of nearly 13,000 species. This redistribution is expected to increase biodiversity in many areas but also lead to extinctions and homogenization of communities.

Arabs or Jews, children who need pain relief in the ER get it

A study published in Annals of Emergency Medicine found that children with broken bones or joint dislocations in northern Israel received equal pain relief, regardless of their ethnicity. The study, which lasted four years, including an 11-week period of armed conflict, showed that opioid therapy was administered to nearly all children...

Making the easiest judgments first

A new study published in PLOS Computational Biology suggests that our brains don't follow a predetermined priority order when categorizing scenery. Instead, they make the easiest judgments first, which can be overridden by manipulating the difficulty level of the task.

Four fairies watch over Sleeping Beauty

Researchers discovered a network of transporters involved in controlling hormone ABA transport to seed embryos, ensuring optimal germination timing. This knowledge can be integrated into breeding programs to prevent premature germination and reduce economic losses.

A marine creature's magic trick explained

A team of scientists at the Weizmann Institute discovered that sea sapphires' colorful appearance is caused by photonic crystals, which enable them to control their visibility. The researchers found that the spacing between the crystal plates determines the color and can be adjusted to make the creature appear invisible or visible

Waste coffee used as fuel storage

Researchers at UNIST developed a simple process to treat waste coffee grounds for methane storage using sodium hydroxide and heating. The process produces a stable carbon capture material with environmental benefits of recycling a waste product.

Who gets a transplant organ

A Rutgers study found that people tend to allocate scarce transplant organs across groups instead of prioritizing individuals with the best chance of a successful transplant. When presented with individual-level information, participants were more likely to make efficient decisions, but when grouped, they allocated resources based on p...

Fingerprinting erosion

A recent study uses color fingerprinting to identify the origin of sediments in the South Tobacco Creek watershed. The technique reveals that nature is more often responsible for sedimentation than previously thought, while human activities have a significant impact on hydrology and erosion.

Queen's University developing new drug against leading causes of death -- sepsis and ARDS

Scientists at Queen's University Belfast have developed a novel anti-inflammatory nanoparticle that shows promise in treating sepsis and Acute Respiratory Distress Syndrome (ARDS), two leading causes of death in hospitalised patients. The treatment, known as SAN101, has the potential to reduce inflammation and prevent organ failure.

Seal pups listen for long distance calls to locate their mothers

Antarctic fur seal pups identify their mothers by detecting the mother's vocal pitch at longer distances and using other components of the vocal signature at closer range. The study found that frequency modulations propagate reliably up to 64 meters, while amplitude modulations are degraded for distances over 8 meters.

For 2-D boron, it's all about that base

Researchers found that 2D boron properties vary based on interactions with metal substrates. Copper is identified as a suitable substrate to guide the formation of flat boron sheets. The discovery opens up new avenues for creating highly conductive 2D boron and exploring its potential applications in fuel cells and other fields.

Neighbors, but not classmates

A Johns Hopkins University sociologist has found that disadvantaged neighborhoods actually expand children's range of educational experiences as they disperse to multiple schools. Affluent neighborhoods, on the other hand, limit options by keeping students close to home.

Penn researchers report long-term remissions in first personalized cell therapy trial

A clinical trial of a personalized cell therapy, CTL019, achieved an overall response rate of 57% and complete remissions in eight out of 14 patients with chronic lymphocytic leukemia (CLL). The therapy, developed by Penn researchers, involves reprogramming patients' own T cells to hunt and kill cancer cells.
