A review article authored by Brazilian researchers evaluated several compounds with therapeutic potential against gastric tumors.
A simple change in the choice of grass varieties for lawns of St. Augustinegrass could be a key tool for fending off fall armyworm infestations, according to new research. While no single St. Augustinegrass cultivar rises above the rest in resisting infestation, mixing varieties may confer some benefits, as fall armyworms clearly preferred single-cultivar plantings in a series of lab tests.
NTU Singapore scientists have developed a sustainable way to demonstrate a new genetic modification that can increase the yield of natural oil in seeds by up to 15% in laboratory conditions.
New evidence from Michigan State University suggests that those who smoke cannabis, or marijuana, weigh less compared to adults who don't. The findings, published in the International Journal of Epidemiology, are contrary to the belief that marijuana users who have a serious case of the munchies will ultimately gain more weight.
What will a three-degree-warmer world look like? When experiencing stress or damage from various sources, plants use chloroplast-to-nucleus communication to regulate gene expression and help them cope. Now, Salk Institute researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus retrograde signaling pathways -- also plays an important role in how proteins are made in damaged chloroplasts, which provides a new insight into how plants respond to stress.
Named after the dark stripes that form inside potatoes after they are cut and fried, zebra chip disease is a potentially devastating affliction that can result in yield losses up to 100% for farmers. Swisher et al. identified a new haplotype, designated haplotype F, that causes zebra chip symptoms in potato. Prior to this discovery, 'only haplotypes A and B were known to cause zebra chip symptoms in potato,' explains Swisher.
The American Bumblebee - a species once more commonly seen buzzing around Southern Ontario - is critically endangered, according to a new study led by York University. The finding, published in Journal of Insect Conservation, found the native North American species, Bombus pensylvanicus, is facing imminent extinction from Canada, considered the highest and most at-risk classification before extinction.
Extracts from the seeds of the Ginkgo biloba tree show antibacterial activity on pathogens that can cause skin infections such as acne, psoriasis, dermatitis and eczema.
Princeton University researchers report that the distribution of forest types worldwide is based on the relationships plant species forged with soil microbes to enhance their uptake of nutrients. These symbioses could help scientists understand how ecosystems may shift as climate change alters the interplay between plants, microbes and soil.
Understanding the ecology and distributions of species in Amazonia is hampered by lack of information about environmental conditions, such as soils. Plant occurrence data are typically more abundant than soil samples in poorly known areas, and researchers from Finland and Brazil have now developed a method that uses both plant and soil data to produce a map of soil properties.
