Researchers at Boyce Thompson Institute have found a new explanation for how aspirin works in the body to reduce the risk of heart disease and certain cancers. Aspirin's active form, salicylic acid, blocks a protein called HMGB1, which triggers inflammation in damaged tissues. The new findings may explain the disease-preventing effects of a low-dose aspirin regimen and offer hope that more effective aspirin-like drugs may be developed for a wide variety of diseases.
A new University of Stirling study has uncovered the secrets of 'pollen thief' bees -- which take pollen from flowers but fail to act as effective pollinators -- and the threat they pose to certain plant species.
A new global review led by the University of Exeter that set out to investigate the hazards of marine plastic pollution has warned that all seven species of marine turtles can ingest or become entangled in the discarded debris that currently litters the oceans.
Striga, also known as witchweed, is a parasitic plant that affects 100 million people in sub-Saharan Africa. Researchers from the University of Toronto have made a discovery that could lead to more effective ways to protect farmers' crops.
Record-breaking temperatures and droughts are directly affecting ecosystems worldwide, an international research team led by UCLA life scientists reports in the journal Global Change Biology.
The study, published online in the Water, Air & Soil Pollution journal (Springer) defines an accurate, inexpensive, high-throughput, and rapid alternative for screening of pathogens from various environmental samples. 'This is the first study to comprehensively assess pathogen concentrations in such a broad variety of environmental sample types while achieving multiple pathogen detection with complete parallel testing by standard (or traditional) methods,' Orlofsky explains.
A report analysing the use of energy in the EU food industry finds that the share of renewable remains relatively small (7 percent) when compared to its part in the overall energy mix (15 percent). Progress in the decarbonization of the food sector is challenging: while farmers and industry have made relevant efforts to improve their energy profile, consumers can also play their part by reducing meat consumption, buying locally and seasonally, and reducing food waste.
Researchers have been able to watch the interior cells of a plant synthesize cellulose for the first time by tricking the cells into growing on the plant's surface, according to a new paper published in Science. Cellulose, the structural component of cell walls that enables plants to stay upright, is the most abundant biopolymer on earth. It's a critical resource for pulp and paper, textiles, building materials, and renewable biofuels.
A study conducted on the Basque coast by a research group indicates that the most polluted waters, the ones with the highest levels of bioconcentration, the highest percentage of intersex fish, etc. exist around waste water treatment plants. Most of these plants are not equipped to eliminate the new compounds, because legislation in this matter has yet to catch up with the development of the chemical industry. The journal Science of The Total Environment has recently published a paper on the subject.
As record ocean temperatures cause widespread coral bleaching across Hawaii, NOAA scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.
