Researchers found that bees can deliver a biological fungicide to strawberry blooms more effectively than mechanical sprayers, reducing infected strawberries by 72 percent. The bee-delivered natural fungicide was as effective as chemical sprays at preventing gray mold, a common disease in strawberries.
The analysis of three Himalayan ice cores reveals a highly detailed record of the last 1,000 years of earth's climate in the high Tibetan Plateau. The data shows that both the last decade and the last 50 years were the warmest in 1,000 years, with at least eight major droughts caused by a failure of the South Asian Monsoon.

A recent study by Ohio State University researchers found that a chemical called tumor necrosis factor (TNF) directly stimulates the brain's digestive control center, causing nausea and vomiting. Elevated TNF levels can lead to long-term changes in digestion function, resulting in persistent symptoms.
A study suggests that people are more likely to vote if they actively dislike a presidential candidate, but only if there is a preferred candidate to support. The research, based on nationwide survey data from 1972 to 1988, found that voters form impressions about candidates similarly to those in other areas of life.

Highlights include new techniques for building tiny blood vessels in the heart and a skin patch containing microscopic needles that inject medication painlessly.
A report by economists suggests that the Federal Reserve should raise interest rates when asset prices rise above fundamentals, to stabilize inflation and prevent economic instability. The strategy aims to keep bubbles from developing in the first place, rather than bursting them once they form.
Young children view violent events in emotional and dramatic terms, while older children see violence in a more intellectual and detached way. The study found that younger children focus on human emotions, such as hate and fear, whereas older children analyze the events using abstract concepts like just war principles.
Researchers found that individuals with autism spectrum disorder (ASD) performed better on a 'false-memory' test due to their impaired ability to use context. This improvement enabled them to recognize words that had been on a word list, while non-autistic subjects struggled with false memories. The study suggests that high-functioning...
Researchers found that celecoxib reduced breast tumor incidence by 68% and average tumor size by 81% in rats. The anti-tumor effects of celecoxib are attributed to its ability to inhibit an enzyme that promotes cancer growth.

The study suggests that tactile feedback could be a powerful tool for human-machine communication in various domains, including aviation, healthcare, and space exploration.
A new study by Ohio State University researchers found that students who read essays on a computer screen struggled to comprehend the text and rated it as less interesting and less persuasive. Despite the same content, computerized texts were harder for students to understand, which may be due to different processing abilities.
Researchers found that cortisol levels remained steady or rose in some people after discussing positive relationship history, despite expecting a decrease. Women who experienced this were more likely to be divorced from their husbands.

Countries belonging to the same preferential trade arrangements (PTAs) were 30-45% less likely to become involved in military disputes, compared to those without such agreements.
A study found that people with a particular variation in the serotonin transporter gene (5-HTT) showed a greater fear response during a laboratory experiment. This variation is linked to increasing regulation of serotonin levels in the brain, which may play a role in anxiety disorders.
Researchers suggest using ultrasound and audible sound waves to measure eye fluid pressure. This could enable glaucoma patients to monitor changes in pressure, taking medication accordingly.
A study found that nearly half of e-mail users make fewer long-distance calls due to the convenience of online communication. E-mail excels in scheduling conflicts, while telephone is preferred for emotional expression and companionship.
Researchers have discovered a metal wire with 'memory' that can help compress broken bones, leading to quicker healing times and better fusion of the bone. The alloy, Nitinol, resists loosening even after being absorbed by the bone, applying consistent pressure to promote proper healing.
A recent study found that a half-day safety program for kindergarten students showed minimal improvement in basic safety skills. The research compared two groups of children, one that participated in the program and another that did not, but found no significant difference in their scores. This suggests that many safety programs, like ...
Researchers found that a 200 milligram-per-day dose of the narcolepsy drug modafinil successfully controlled fatigue in patients with MS, a disease that attacks the nervous system. The study involved 72 patients with severe fatigue and MS, who reported significantly less fatigue when taking the 200 mg dose compared to the placebo.
Researchers at Ohio State University found that people with high hostility and anger levels showed higher homocysteine concentrations, associated with coronary heart disease. The study also revealed that men are more likely to have higher homocysteine levels due to increased hostility and inhibition of anger.

The study found that those who reported frequent thoughts of their biological father experienced higher levels of psychologica...
Researchers found that older adults' inability to suppress unwanted information leads to increased prejudicial thoughts. Despite efforts to overcome biases, older adults tend to hold stereotypical views on intelligence and race.
Researchers found that oxidants are necessary for endothelial cell migration and wound healing after vascular injury. Oxidants stimulate the production of actin fibers, allowing cells to move towards injured sites.
A study of 558 students and professionals found that religious individuals value interdependence with others, whereas non-religious people prioritize self-reliance. This contradicts common criticisms that religious dependence is a sign of weakness.
Researchers found that using handrails on a stepping machine reduces maximum heart rates by up to 5% and oxygen uptake by up to 8%. Women are advised to keep their hands off the rails for optimal results. The study, published in Research in Nursing & Health, suggests women should use a light touch or avoid using handrails altogether.

A study by Ohio State University found that some energy bars give a sudden spike in blood sugar levels, unlike the moderate increase claimed for endurance athletes. The Ironman PR Bar had a steady effect due to its balanced carbohydrate and protein content.
New research suggests that non-mutational gene defects, involving DNA methylation, contribute significantly to the development of cancer. Up to 10% of genes in some tumor types are found to be inactivated by aberrant DNA methylation, suggesting a much larger role for this process than previously thought.
Researchers found a correlation between unexplained foot fractures and low bone density, a primary symptom of osteoporosis. The study suggests that podiatrists should inspect patients with at-risk conditions for early signs of osteoporosis.

Researchers found that using methane with a palladium-based catalyst can remove nearly 100% of nitric oxide from stack gases, a process considered more environmentally friendly and cost-effective than current methods. However, the sulfur dioxide present in some emissions interferes with the reaction.
Researchers found that short periods of stress can enhance the immune system's response to foreign invaders, such as bacteria and viruses. The study showed that mice with normal gamma interferon function had a more robust immune response after being stressed.
Researchers at Ohio State University found a strong correlation between high credit card debt and physical impairment. People experiencing stress over debt reported worse health outcomes than those with lower debt levels. The study suggests that high credit card debt can have a detrimental impact on overall well-being.
