Published Habitat will dictate whether ground beetles win or lose against climate change
(via sciencedaily.com) The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.
Published Deceptive daisy's ability to create fake flies explained
(via sciencedaily.com) Researchers have discovered how a South African daisy makes fake lady flies on its petals to trick male flies into pollinating it.
Published As the worm turns: New twists in behavioral association theories
(via sciencedaily.com) Physicists have developed a dynamical model of animal behavior that may explain some mysteries surrounding associative learning going back to Pavlov's dogs.
Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB
(via sciencedaily.com) Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Researchers discover a way to fight the aging process and cancer development
(via sciencedaily.com) Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Scientists warn of rise in potentially fatal bacterial infection due to global warming
(via sciencedaily.com) Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite during contact with seawater. The researchers predict that by 2041--2060 infections may spread to encompass major population centers around New York. Combined with a growing and increasingly elderly population, who are more susceptible to infection, annual case numbers could double.
Published Known active ingredient as new drug candidate against mpox
(via sciencedaily.com) Mpox -- previously known as 'monkeypox' -- is currently spreading worldwide. Researchers have now identified a compound that could help fight the disease.
Published Memory B cell marker predicts long-lived antibody response to flu vaccine
(via sciencedaily.com) Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
Published Towards reducing biodiversity loss in fragmented habitats
(via sciencedaily.com) By combining lab experiments and mathematical modelling, researchers have found a way to predict the movement of species that could guide conservation efforts to reconnect fragmented habitats.
Published Hidden 'super spreaders' spur dengue fever transmission
(via sciencedaily.com) For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of 'hidden' infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Next epidemic could be spotted early in wastewater
(via sciencedaily.com) Original source Researchers behind the UK's first pilot public health surveillance system based on analysis of wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.
Published New mosquito species reported in Florida
(via sciencedaily.com) A mosquito known only by its scientific name, Culex lactator, is the latest to establish in the Sunshine State, according to a new study.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published Emergence of extensively drug-resistant Shigella sonnei strain in France
(via sciencedaily.com) Shigellosis, a highly contagious diarrheal disease, is caused by Shigella bacteria circulating in industrializing countries but also in industrialized countries. Scientists who have been monitoring Shigella in France for several years have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei.
Published Coffee plantations limit birds' diets
(via sciencedaily.com) A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
Published Parasites alter likelihood of fish being caught by anglers
(via sciencedaily.com) Parasitic infections in salmonid fish can increase or decrease their vulnerability to angling, depending on their body condition.
