| Posted: 31 Jan 2022 08:05 AM PST Our sensory systems provide us with immediate information about the world around us. Researchers have created the first sensory map for smell. The map details how the fruit fly's olfactory receptor neurons, the components that sense smell, are organized within the insect's sensory hairs. |
| Simplified antibiotic may set the stage for antitumor treatments Posted: 31 Jan 2022 08:05 AM PST Garden soil houses a variety of bacteria and their natural byproducts -- including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments. |
| Low volcanic temperature ushered in global cooling and the thriving of dinosaurs Posted: 31 Jan 2022 08:05 AM PST Dinosaurs came to flourish during the Jurassic period after a volcanic eruption roughly 201 millions years ago wiped out many marine and land animals, leaving them able to evolve and grow. Now, further details about this eruption and the mass extinction have been revealed. A group of researchers demonstrated how low temperature magma slowly heated sedimentary rocks, causing high sulfur dioxide and low carbon dioxide emissions, a process which cooled the earth. |
| Some Finnish forest owners do not believe in biodiversity loss – for others it is a crisis Posted: 31 Jan 2022 06:50 AM PST We should start talking about biodiversity loss denial, just like we discussed climate change denial in the recent past, researchers say. |
| Locations of ancient Maya sacred groves of cacao trees discovered Posted: 31 Jan 2022 06:50 AM PST A team has identified nine sinkholes in the Yucatan peninsula that contain evidence of both cacao trees and ancient ceremonial rituals. |
| Researchers discover how lactic acid weakens anti-tumor defenses Posted: 28 Jan 2022 11:13 AM PST It has long been known that lactic acid is produced in large quantities by cancer cells and that this lactic acid disrupts our defense against tumors. However, scientists did not know exactly how this happens. Now researchers report they have found the answer. |
| The secrets of fish survival in the desert Posted: 26 Jan 2022 11:42 AM PST How life manages to persist in unpredictable and extreme environments is a major question in evolution. For aquatic animals, extreme environments include those with little water such as the deserts of central Australia. Adaptations in the genome linked to the very dry conditions of the Australian outback ensure populations of desert fish survive in harsh conditions, according to scientists. |
| Genomic structure of microbial communities can predict metabolic activity Posted: 26 Jan 2022 09:24 AM PST A new study by ecologists shows that the genes present in a microbial community can predict the community's dynamic metabolic activity, with implications for the nitrogen cycle and other important biogeochemical processes. |
