Published GPCR structure: Research reveals molecular origins of function for a key drug target



Scientists reveal how G protein-coupled receptors, major therapeutic drug targets, decode critical properties of their ligands.
Published New tool unifies single-cell data



A new methodology that allows for the categorization and organization of single-cell data has been launched. It can be used to create a harmonized dataset for the study of human health and disease.
Published Location, location, location: The hidden power of intracellular neighborhoods



New findings provide details about the hidden organization of the cytoplasm, showing it makes a big difference where in that cellular broth that messenger RNA (mRNA) get translated into proteins. The findings hold promise for increasing or altering the production of proteins in mRNA vaccines and therapies.
Published The future of canine stem cell therapy: unprecedented, painless, and feeder-free



Scientists have developed an efficient, non-invasive, and pain-free method to generate canine-induced pluripotent stem cells (iPSCs). They identified six reprogramming genes that can boost canine iPSC generation by 120 times compared to conventional methods using fibroblasts. The iPSCs were created from urine-derived cells without the need for feeder cells, an impossible feat until now. Their findings are expected to advance regenerative medicine and genetic disease research in veterinary medicine.
Published The key mechanism to cell growth has been elucidated



Researchers have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.
Published How national policies affect forests in border regions



How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Bugs that help bugs: How environmental microbes boost fruit fly reproduction



A research group found that in female fruit flies, microorganisms enhance reproductive function, boosting the number of cells that form eggs and the number of mature eggs. This is done by controlling the release of hormones to speed up cell division in the ovaries, and limiting programmed cell death. These findings could improve reproductive medicine and could aid the development of new methods to enhance fertility.
Published Researchers solve mystery behind DnaA protein's role in DNA replication initiation



Scientists have uncovered how DnaA, the master key to DNA replication, opens the door to bacterial growth. This breakthroughpaves the way for new antibiotics to combat the rising tide of antibiotic resistance.
Published New insights revealed on tissue-dependent roles of JAK signaling in inflammation



Researchers have gained a deeper understanding of the nuanced roles of JAK inhibitors, or modulators, in inflammation across various cell types and tissues.
Published How researchers are 'CReATiNG' synthetic chromosomes faster and cheaper



A new technique to clone and reassemble DNA, dubbed CReATiNG, could simplify and lower the cost to make synthetic chromosomes. Potential applications are numerous, including pharmaceutical production, biofuel generation, cancer therapies, and environmental cleanup using modified organisms. The method adds a powerful, versatile tool to the burgeoning field of synthetic biology.
Published Discovery: Plants use 'Trojan horse' to fight mold invasions



Scientists have discovered that plants send tiny, innocuous-seeming lipid 'bubbles' filled with RNA across enemy lines, into the cells of the aggressive mold. Once inside, different types of RNA come out to suppress the infectious cells that sucked them in.
Published Tree plantations can get better with age -- but original habitats are best



Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.
Published New larks revealed in Africa



Researchers have studied the relationships between five closely related species of larks that occur in Africa south of the Sahara. Two of these have not been observed for decades, so the researchers analyzed DNA from museum specimens, some of which were over 100 years old.
Published A trillion scents, one nose



A research team has uncovered a previously undetected mechanism in mice -- starring the genetic molecule RNA -- that could explain how each sensory cell, or neuron, in mammalian noses becomes tailored to detect a specific odor chemical.
Published Cells of the future: A key to reprogramming cell identities



The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.
Published Multitasking microbes: Scientists engineer bacteria to make two valuable products from plant fiber



Researchers have engineered bacteria that can produce two chemical products at the same time from underutilized plant fiber. And unlike humans, these multitasking microbes can do both things equally well. The discovery could help make biofuels more sustainable and commercially viable.
Published New study examines the relationship between the rate of wound healing, the circadian rhythm, and 'hair' on cells



Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis. Most cells in mammalian bodies have cilia of some sort, which are hair-like structures that perform a variety of functions such as movement for motile cilia and aiding in structure in function for non-motile, or primary, cilia. The primary cilia also act as a sensory organ for the cell, a function which has illuminated the primary cilia's potential role in the healing process and how bodies heal at a different rate according to our circadian rhythm. In this research, the role of the primary cilia, biological clock and wound healing is explored.
Published Protein allows poison dart frogs to accumulate toxins safely



A newly identified protein helps poison dart frogs accumulate and store a potent toxin in their skin which they use for self-defence against predators.
Published Genetics of host plants determine what microorganisms they attract



Plants often develop communities with microorganisms in their roots, which influences plant health and development. Although the recruitment of these microbes is dictated by several factors, it is unclear whether the genetic variation in the host plants plays a role.
Published Scientists collect aardvark poop to understand how the species is impacted by climate in Africa



In a new study of aardvarks, researchers spent months in sub-Saharan Africa collecting poop from the animal and concluded that aridification of the landscape is isolating them, which they say could have implications for their long-term survival.
