Remove hidden cancer messengers: How extracellular vesicles help spread tumors
This graphic shows paracrine adhesion signaling in small extracellular vesicles. It secretes a protein called galectin-3. This promotes endocytosis so that the vesicles can be absorbed into recipient cells. Credit: Suzuki Kenichi et al. , Gifu University Most cells in the body send out small messengers called extracellular vesicles that carry proteins, lipids, and other biologically active molecules to other…

Nanoparticle immunotherapy shows the possibility of stopping the spread of pancreatic cancer
The nanoparticles developed by UCLA aim to reprogram the human liver to attack pancreatic cancer with mRNA vaccines (curved hatched red lines) and immune-activating fragments of genetic material (red dots). Credits: University of California, Los Angeles Pancreatic cancer remains one of the most difficult tumors to treat. This is because it is often discovered in progressive stages when the disease…

Research uses the sweet secrets of plant nectar to bite mosquito spread disease
In a new study, scientists analyzed the chemistry of nectar in several plants known to be used by mosquitoes for foods in malaria-prone regions. They suggest identifying and removing these plants from the landscape from nearby people’s homes, suggesting that they could tackle malaria infections and other tropical diseases such as Zika, West Nile and dengue fever.

Where do invasive species spread and why? Researchers take a new approach to finding the answer
Credit: Pixabay/CC0 Public Domain Science makes it difficult for scientists to simulate spreads and predict where they will go next, as invasive species (such as spotted tilapia) are constantly moving. Researchers at the University of Florida Institute of Food and Agricultural Sciences will dig deeper to understand why certain locations are susceptible to invasions by non-native plants and animals, and…
