Scientists uncover the distribution and physiological role of planteose Posted: 07 Jan 2022 05:44 AM PST The findings of this study are intended to aid botanists who specialize in crop protection in better understanding the distribution of planteose throughout the endosperm, perisperm, and seed coat of Orobanche minor -- a root parasitic weed, which is consistent with planteose's role as a storage carbohydrate. The findings of this work demonstrate unequivocally that the enzyme OmAGAL2, which is involved in the hydrolysis of planteose, is a promising molecular target for root parasitic weed control. |
Posted: 07 Jan 2022 05:44 AM PST Egg white is one of the most important protein ingredients for the food industry. The first assessment of the environmental impact of egg white protein -- ovalbumin -- production by fungus Trichoderma reesei shows that the ovalbumin produced by precision fermentation reduced land use requirements by almost 90 per cent and greenhouse gases by 31--55 per cent compared to the production of its chicken-based counterpart. |
Mechanism that helps immune cells to invade tissues Posted: 06 Jan 2022 11:37 AM PST To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within. Scientists have now discovered how immune cells protect their sensitive insides as they squeeze between tissue cells. The team lays the foundation for identifying new targets in cancer treatment. |
California mice eat monarch butterflies Posted: 06 Jan 2022 11:37 AM PST At the largest winter monarch aggregation in central Mexico, scientists have observed that rodents attack monarchs that fall to the ground. Biologists have now discovered that the western harvest mouse also eats grounded monarchs. Documenting this new feeding behavior is a reminder of little we know about the interactions that may be lost as insect populations decline. |
Archaeological dig reveals participants in California’s Gold Rush dined on salted Atlantic cod Posted: 06 Jan 2022 11:36 AM PST An excavation at Thompson's Cove in San Francisco shows 'Atlantic cod were imported during the 1850s, likely as a (largely) deboned, dried and salted product from the East Coast of the United States.' The analysis underscores the importance of global maritime trade in northern California during the Gold Rush. |
Microbes produce oxygen in the dark Posted: 06 Jan 2022 11:36 AM PST It is common knowledge that there would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also produced without sunlight, possibly deep below the ocean surface. |
Researchers develop automated method to identify fish calls underwater Posted: 06 Jan 2022 09:23 AM PST Researchers have developed an automated method that can accurately identify calls from a family of fishes. |
Unexpected hope for millions as bleached coral reefs continue to supply nutritious seafood Posted: 06 Jan 2022 08:15 AM PST Coral reef ecosystems support diverse small-scale fisheries -- and the fish they catch are rich in micronutrients vital to the health of millions of people in the tropics, a new study reveals. And, counter-intuitively, following bleaching events that kill off coral and can transform the composition of reef ecosystems, reef fisheries can remain rich sources of micronutrients, even increasing in nutritional value for some minerals. The findings show that the availability of micronutrients from coral reef small-scale fisheries may be more resilient to climate change than previously thought. |
Preserving the goods: A new technique for isolating intact lysosomes from cell cultures Posted: 06 Jan 2022 08:00 AM PST Lysosomes are organelles that play essential roles in cellular digestion and waste management, and lysosomal dysfunction typically leads to serious diseases. In a recent study, scientists developed a novel technique to extract intact lysosomes from cells using magnetic nanoparticles. Their approach is much faster than previous methods and yields samples with high purity, allowing for a better understanding of lysosomes and their metabolites and, hopefully, paving the way to treatments for lysosomal disorders. |
Healthful food for children is the same as for adults Posted: 06 Jan 2022 07:03 AM PST There is no difference between healthful foods for adults and for children aged 2 and older, except for age-appropriate adjustments in texture and portion size, according to experts in nutrition. |
Marijuana users’ risk of deadly complication doubles after rare type of bleeding stroke Posted: 06 Jan 2022 07:03 AM PST Among adults with a certain type of bleeding stroke, those who used marijuana within the last 3-30 days were more than twice as likely to develop a serious stroke complication that increases the risk of death and disability. The study is the largest to examine the impact of THC, the mood-changing ingredient in marijuana, on complications after a bleeding stroke. |
