Scientists discover that people prefer certain smells when sniffed through one nostril over the other. The left nostril is more accurate for identifying odours, while the right nostril enhances pleasantness perception. This finding fits with brain processing theories and may lead to further research on smell perception.
Researchers at Case Western Reserve University will use the grant to identify a genetic link in colon cancer development and screen more families with high risk. The study aims to uncover common genetic mutations that make individuals vulnerable to adenomatous polyps.
Researchers found that 10% of HIV-infected individuals experience severe liver toxicity while taking antiretroviral drugs, with ritonavir being the worst offender. Doctors should monitor liver enzyme levels to ensure safe treatment.
Researchers used molecular probes to identify a toxic diatom linked to the deaths of over 400 California sea lions. The DNA probe tests detected a short but significant bloom in Pseudo-nitzschia australis, allowing researchers to connect the sea lion deaths to the bloom.
Researchers found that expectant fathers' hormones fluctuate during pregnancy, mimicking their partners' changes. Testosterone levels dropped significantly after birth, and lower levels were associated with increased paternal behavior.
The NIH conference aims to develop a framework for independent research on medical implants retrieved after surgery or at autopsy. The conference seeks to address the challenges and opportunities in collecting and analyzing data on implant performance, with a focus on improving public understanding and policy-making.
A study published in Urology found that men with prostate cancer are more likely to remain continent and potent after surgery performed by highly experienced surgeons. The study's potency and continency rates were the highest ever reported, with up to 93% of patients reporting continency and 65% reporting potency.
A study by Johns Hopkins researchers found that videotaping surgeries can improve outcomes in radical prostatectomy. The study, which involved 62 patients, showed that minor differences in surgical techniques can have a major impact on results. Surgeons who perform successful procedures should review the footage to identify key factors.
A skills-based program can significantly increase a student's confidence in refusing an offer to smoke and their expectation that peers will accept the decision. However, it had little effect on objectively evaluating favorable images of smoking.
A new study at Oregon State University found that low levels of nitrate and nitrite in water can kill some species of amphibians, especially during their larval stages. The study suggests that water quality criteria set by the EPA may not guarantee the survival of all protected and endangered amphibian species.
A new study reveals that phytoplankton quality, rather than quantity, is a critical factor in supporting thriving fish populations and clear water in lake ecosystems. Phytoplankton with high concentrations of omega-3 fatty acids support higher zooplankton growth rates, leading to positive effects on both ends of the food chain.
Researchers found that calculations taking longer than 26 months on current hardware are not worth starting. Instead, delaying until a more powerful computer is available can save time and resources. This strategy allows for optimal use of limited budgets for computers.
Researchers have found that PR39 promotes angiogenesis by blocking the degradation of a key transcription factor, HIF-1alpha. The newly formed vessels were fully functional in mice studies, offering a promising tool for treating coronary artery disease and peripheral vascular disease.
Researchers at the University of Washington discovered that HIV alters gene function in cells within three days of infection, affecting T-cell signaling and immune system functions. The study used cDNA microarray technology to examine gene expression levels and may lead to new treatments for the disease.
