The studies also explored the emergence of new towns as instruments for politics, economics, and culture in late Middle Ages.
Researchers found that BRCA1 and BRCA2 mutation carriers experience a similar reduction in breast cancer risk with increasing number of pregnancies carried to full-term, parallel to that in the general population. Additionally, they discovered that first childbirth at age 20 years or older is associated with increased risk of breast ca...
A national study reveals that nearly 60% of older diabetics are not taking ACE inhibitors or ARBs, despite clear signs of problems. The study's findings highlight the need for improved awareness and incentives to encourage responsible prescribing and increased use of these life-saving medications.
Researchers explore risk factors for dementia, including the Mediterranean diet and obesity, as well as novel treatments for Alzheimer's and multiple sclerosis. Experimental therapies also show promise in treating ALS and stroke, with potential applications in other neurodegenerative diseases.
Researchers found that animals can detect movement direction from foot cues, which may help avoid predators. This low-level locomotion detector is part of an evolutionary old system, suggesting animal brains are 'hard-wired' for this type of recognition.
MoodViews uses language technology to predict global mood, analyzing millions of blogger messages daily, with potential applications in marketing, psychology, and journalism.
A study found that higher levels of education are associated with lower prevalence of coronary artery calcium, a marker of subclinical cardiovascular disease. Individuals with less than a high school degree had four times higher CAC prevalence compared to those with more than a college education.
The NIST quantum key distribution system has achieved a record speed of 4 million bits per second (bps) over 1 kilometer of optical fiber, twice the previous record. The system uses single photons and operates at an error rate of only 3.6 percent, enabling highly secure key exchange.
Researchers at Rice University have created nanoparticles called nanostars, which exhibit strong spectral signals and can be used to discern the three-dimensional orientation of molecules. This discovery has significant potential for 3D molecular sensing applications.
Researchers found sex differences in brain regions responsible for pain transmission, with males and females responding differently to pain stimuli. Persistent pain activates this pathway more strongly in males than females, highlighting the need for tailored pain treatments.
Researchers identify a single mechanism linking ciliary, serotonergic and ion flow mechanisms to control embryonic laterality. The study challenges previous hypotheses on the role of cilia in left/right asymmetry, providing insight into human development and birth defects related to left/right asymmetry.
UB researchers have discovered an agent, L-AP4, that activates group III metabotropic glutamate receptors and reverses damage caused by rotenone. The findings could lead to a new treatment for Parkinson's disease.
The lung has a unique innate immune system, protected by alveolar macrophages that are repressed in steady state, activated when needed, and then re-repressed. This complex circuit allows for brief activation periods to fight invading microorganisms.
Researchers found cuttlefish can detect contrast differences of at least 15%, suggesting they use intensity matching for camouflage. The study's findings shed light on the complex visual processing of these cephalopods, an ideal model for studying camouflage.
A new study finds that health care spending generates significant health benefits, with a return on investment of $1.55 to $1.94 for every dollar spent. The research demonstrates the value of estimating the impact of health care investments and challenges policymakers to consider cost-effectiveness in their decision-making.
Infants born to mothers with extremely short or long intervals between pregnancies face increased risks of preterm birth, low birth weight, and small for gestational age. Short intervals (less than 6 months) result in a 40% increase in preterm birth risk, while long intervals (more than 59 months) lead to a 20-43% higher risk.
