Published A taste for carbon dioxide
(via sciencedaily.com) Original source The remarkable affinity of the microbial enzyme iron nitrogenase for the greenhouse gas CO2 makes it promising for future biotechnologies.
Published New way inflammation impacts cell communication
(via sciencedaily.com) Original source Researchers have made significant progress in understanding how cells communicate during inflammation.
Published Revealing the mysteries within microbial genomes
(via sciencedaily.com) Original source A new technique will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the roles and impact of individual species within the planet's diverse microbiomes.
Published Beige fat cells with a 'Sisyphus mechanism'
(via sciencedaily.com) Original source A new class of fat cells makes people healthier. The cells consume energy and produce heat through seemingly pointless biochemical reactions.
Published New mechanism of action kills cancer cells
(via sciencedaily.com) Original source Conventional cancer drugs work by triggering apoptosis, that is programmed cell death, in tumor cells. However, tumor cells have the ability to develop strategies to escape apoptosis, rendering the drugs ineffective. A research team now describes a new mechanism of action that kills cancer cells through ferroptosis.
Published C-section antibiotics impact the infant microbiome far less than infant diet
(via sciencedaily.com) Original source Caesarean section recipients are usually given prophylactic antibiotics just before the procedure to prevent later infections at the surgical site. But there have been concerns about whether these antibiotics may have a negative impact on newborns and their microbiomes if the drugs travel through the umbilical cord and reach the baby before the cord is cut. Now, a study has confirmed that although these antibiotics can cause subtle changes to the infant microbiome, they are much less significant than the impact of how the babies are fed.
Published A ketogenic diet could improve the response to pancreatic cancer therapy
(via sciencedaily.com) Original source Scientists have discovered a way to get rid of pancreatic cancer in mice by putting them on a high fat, or ketogenic, diet and giving them cancer therapy.
Published Decoding the world's largest animal genome
(via sciencedaily.com) Original source Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Researchers call for genetically diverse models to drive innovation in drug discovery
(via sciencedaily.com) Original source Researchers unveiled an approach to drug discovery that could revolutionize how we understand and treat diseases. Their commentary explains the limitations of studies using traditional mouse models and proposes using genetically diverse mice and mouse and human cells to better predict human responses to drugs and diseases.
Published Giant fossil seeds from Borneo record ancient plant migration
(via sciencedaily.com) Original source Ancient fossil beans about the size of modern limes, and among the largest seeds in the fossil record, may provide new insight into the evolution of today's diverse Southeast Asian and Australian rainforests, according to researchers who identified the plants.
Published Scientists condition crocodiles to avoid killer cane toads
(via sciencedaily.com) Original source Scientists have trialled a new way to protect freshwater crocodiles from deadly invasive cane toads spreading across northern Australia.
Published Common equine painkiller disrupts assisted reproduction technique efficiency in mares
(via sciencedaily.com) Original source Researchers have discovered that phenylbutazone, a non-steroidal anti-inflammatory drug (NSAID) commonly prescribed in horses, can affect the ability of a mare's egg cells -- called 'oocytes' -- to become viable embryos, which is a crucial step in assisted reproduction in horses.
Published Exciting advance in stem cell therapy
(via sciencedaily.com) Original source A new technique for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential.
Published Significant link found between heme iron, found in red meat and other animal products, and type 2 diabetes risk
(via sciencedaily.com) Original source Higher intake of heme iron, the type found in red meat and other animal products -- as opposed to non-heme iron, found mostly in plant-based foods -- was associated with a higher risk of developing type 2 diabetes (T2D) in a new study. While the link between heme iron and T2D has been reported previously, the study's findings more clearly establish and explain the link.
Published Pit-building venom mixers
(via sciencedaily.com) Original source Researchers show that the adaptation of antlions to their ecological niche has also changed their venom. They compared the venom system of antlion and closely related green lacewing larvae. Antlions produce a much more complex venom from three different venom glands than lacewing larvae do. All the venom proteins identified come from the insects themselves, not from symbiotic bacteria. Some of the toxins are new and appear to be unique to antlions. Waiting for their victims in pitfall traps in the sand, antlions can use their venom to immobilize larger prey. The venom therefore plays an important ecological role in adapting to their barren habitat.
Published Surprising insight into cancer comes from unique plant species that find different solutions to evolutionary challenges
(via sciencedaily.com) Original source A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer.
Published Rewriting the evolutionary history of critical components of the nervous system
(via sciencedaily.com) Original source A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published Reduce, reuse, 're-fly-cle'
(via sciencedaily.com) Original source Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.
Published Starvation and adhesion drive formation of keratinocyte patterns in skin
(via sciencedaily.com) Original source Cell-cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion researchers find.
Published Study reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease
(via sciencedaily.com) Original source Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease. Oleoyl-ACP-hydrolase (OLAH) is an enzyme involved in fatty acid metabolism. A study shows that OLAH drives severe disease outcomes.
