Studies show that when faced with a threat, our bodies respond with fight-or-flight responses and engage perceptual biases to misperceive objects as being closer. However, this effect is absent in cases of disgust. These findings support the threat-signal hypothesis, suggesting that perception can be biased to promote functional action.
A new coronavirus, hCoV-EMC, has been linked to severe disease in humans and can infect cells from various bat species and pigs. The virus uses a different receptor than SARS, but its ability to transmit between animals and humans repeatedly remains uncertain.
A study found that consumers are more likely to buy a product they previously focused on, while ignoring a product decreases its purchasing chances. Companies can exploit this by drawing attention through advertising or packaging to gain long-term advantages.
Women who smoke even light-to-moderate cigarettes are at higher risk of sudden cardiac death, with the risk climbing by 8% for every five years of continued smoking. Quitting can significantly reduce and eliminate this risk over time.
Researchers suggest that the large size of sauropod dinosaurs may be attributed to a high C/N ratio in their plant-based diet. This theory proposes that young sauropods had a metabolism similar to modern mammals, while adults might have relied on humps of fat reserves instead of heat dissipation due to overheating.
A combination of diagnostic tests, including MRI, PET and cerebrospinal fluid biomarkers, can improve the prediction of conversion from mild cognitive impairment to Alzheimer's disease. The study found that combining these tests reduced false classifications and increased accuracy compared to clinical testing alone.
