Researchers observed that giant unicellular slime molds change tube diameters in response to nutrient sources, imprinted in the hierarchy of thinner and thicker tubes. This reorganization persists for up to 30 minutes before the organism migrates toward the nutrient source, suggesting a mechanism for memory formation.
A recent study confirmed that a genetic modeling technique accurately predicts the extinction of an isolated bobcat population. The research found that the Cumberland Island bobcats have lost about 15% of their genetic diversity over the past 30 years, with low levels of inbreeding.
Researchers have developed improved gene vectors for ocular gene therapy, allowing for widespread delivery and reducing risks associated with traditional approaches. These vectors are being tested in clinical trials and have shown promise in restoring daylight vision in animal models of achromatopsia.
Researchers have isolated monoclonal antibodies that effectively target and inhibit the growth of tuberculosis germs in laboratory mice. These biological antibiotics show promise as an alternative to traditional chemical antibiotics, offering a safer and more stable treatment option.
Researchers developed a fusion protein that selectively targets tumor neovasculature, inhibiting tumor growth in immunocompetent mice. The antibody-based delivery of engineered cytokines shows potential for improved therapeutic effects.
New research published in JNeurosci found that recalling similar memories triggers divergent brain activity patterns, resulting in better memory performance. This study suggests that the brain exaggerates differences between similar events, which can be advantageous in distinguishing between similar things and preventing confusion.
The study reveals chemical traces of grapes in medieval amphorae, suggesting a prosperous wine trade across the Mediterranean. The discovery implies that the Islamic community in Sicily produced and exported wine, contradicting previous assumptions about their consumption habits.
