Of body and mind, and deep meditation

Integrative body-mind training (IBMT) alters blood flow and electrical activity in the brain, breathing quality, and even skin conductance, allowing for a state of relaxation, calmness, and reduced stress. IBMT improves connection between central nervous system structures and promotes integration of brain and body.

Caltech, UCSF scientists determine how body differentiates between a scorch and a scratch

Scientists identify distinct subsets of pain-sensing neurons responsible for detecting heat and mechanical pain, challenging conventional wisdom that the brain disentangles these sensations. The study's findings have potential implications for understanding and treating conditions like diabetic neuropathy.

Mine safety system goes global

A real-time risk management system will be available globally after a Queensland company was awarded a license to commercialise the CSIRO technology. Nexsys allows underground coal mines to interrogate vast amounts of digital information from various sensors and systems, providing real-time risk management and decision support.

Protein identified as critical to insulating the body's wiring could also become treatment target

Researchers at Medical College of Georgia have identified a critical protein called erbin that regulates insulation in the peripheral nervous system. Impaired myelin formation is linked to neurological and psychiatric diseases, while erbin's role in cancer therapy provides a potential new site for targeted treatment.

Genetic factors may predict depression in heart disease patients

A recent study found that genetic variations involving endothelial dysfunction and platelet aggregation contribute to depressive symptoms in individuals with heart disease. Researchers discovered a significant association between one marker within the vonWillebrand factor gene and depressive symptoms.

Capsules encapsulated

Scientists have created a microcontainer that can hold thousands of individual 'carrier units' - a 'capsosome'. These are polymer capsules with embedded liposomes, combining the advantages of both systems. The capsosomes were produced by several steps and demonstrated successful transport of an enzyme model cargo.

Exposure to 2 languages carries far-reaching benefits

A Northwestern University study found that bilingual participants mastered nearly twice the number of words as monolinguals when learning an invented language. The research suggests that early exposure to two languages carries far-reaching benefits, making bilingual individuals better language learners in general.

Low-income breast cancer patients skipping hormonal therapy, increasing their risks

A study by Duke University Medical Center found that only 64% of low-income women with hormone receptor-positive breast cancer filled any prescriptions for hormonal therapy within 12 months after diagnosis. The researchers also discovered that 40% of the women stopped taking their medication regularly, and 20% stopped using it altogether.

Risk of facial fractures in motor vehicle crashes decreasing

The study found a decrease in facial fracture incidence over the years, likely due to advancements in vehicle safety features. Individuals restrained with seat belts alone or with airbags were less likely to sustain facial fractures, highlighting the importance of restraint use in injury prevention.

Web-based consultations may reduce referrals to dermatologists

A web-based system allowing general practitioners to confer with specialists about skin conditions has been shown to reduce referrals to dermatologists by approximately 20%. The study found that in-person consultations were preventable for 39% of patients who received teledermatologic consultations, compared to 18.3% in the control group.

Disruption of immune-system pathway key step in cancer progression, Stanford study shows

A Stanford University study found that disrupting the interferon pathway, a critical immune signaling mechanism, can lead to cancer progression and impaired immune response. This defect was detected in patients with breast, melanoma, and gastrointestinal cancers, suggesting a possible explanation for treatment failures.

New lead on malaria treatment

Researchers at Johns Hopkins University School of Medicine have discovered a natural compound that can stop malaria parasite growth, interacting with the parasite's MetAP2 protein. The compound, fumarranol, was found to be less toxic than existing medications and showed promise in treating malaria in mice.

Quick test for prostate cancer

Researchers have developed a new 3-minute test that measures the level of citrate in fluid samples from the prostate gland to detect prostate cancer. The technique uses light energy and can provide an accurate way to screen and diagnose the disease, particularly in its early stages.

How glucocorticoid drugs protect the heart

Researchers found that glucocorticoids induce production of PGD2, which protects rodent hearts from ischemia/reperfusion injury. Synthetic glucocorticoids may be more beneficial for humans following a heart attack than traditional ones.
