Published Distributed workload in the fly brain
(via sciencedaily.com) Original source To distinguish motion patterns, a neuronal computation is performed three times in a row.
Published Climate and human land use both play roles in Pacific island wildfires past and present
(via sciencedaily.com) Original source It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.
Published A more effective experimental design for engineering a cell into a new state
(via sciencedaily.com) Original source A new machine-learning approach helps scientists more efficiently identify the optimal intervention to achieve a certain outcome in a complex system, such as genome regulation, requiring far fewer experimental trials than other methods.
Published Researchers studied thousands of fertility attempts hoping to improve IVF
(via sciencedaily.com) Original source By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization.
Published Researchers propose a unified, scalable framework to measure agricultural greenhouse gas emissions
(via sciencedaily.com) Original source Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, scientists have proposed a supercomputing solution to help measure individual farm field-level greenhouse gas emissions.
Published Dense measurement network links air pollution and common agricultural practice
(via sciencedaily.com) Original source The annual burning of crop residue in India causes widespread air pollution, particularly in the northwestern regions. A group of international researchers has used low-cost yet reliable instruments to gauge the effects of air pollution in these areas.
Published Edges cause cilia to quickly synchronize their beating pattern
(via sciencedaily.com) Original source Border regions can cause cilia to coordinate their motion creating a unidirectional wave that is essential for biological functions. Scientists proposed a new model describing this synchronized pattern driven by the border region.
Published Groundbreaking mathematical proof: New insights into typhoon dynamics unveiled
(via sciencedaily.com) Original source A research team has provided irrefutable proof that certain spherical vortices exist in a stable state.
Published Small but mighty new gene editor
(via sciencedaily.com) Original source A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Genome study reveals 30 years of Darwin's finch evolution
(via sciencedaily.com) Original source An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin's finches. The study has revealed the genetic basis of adaptation in this iconic group.
Published Allergy study on 'wild' mice challenges the hygiene hypothesis
(via sciencedaily.com) Original source The notion that some level of microbial exposure might reduce our risk of developing allergies has arisen over the last few decades and has been termed the hygiene hypothesis. Now, an article challenges this hypothesis by showing that mice with high infectious exposures from birth have the same, if not an even greater ability to develop allergic immune responses than 'clean' laboratory mice.
Published Ancient plant wax reveals how global warming affects methane in Arctic lakes
(via sciencedaily.com) Original source In a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to slow changes in Earth's orbit 11,700 to 4,200 years ago. They found that warming potentially could lead to a previously under-appreciated flux in methane emissions from lakes.
Published Gut inflammation caused by substance secreted by microbe
(via sciencedaily.com) Original source A rare subtype of the world's most common parasite, Blastocystis, has been found to produce a unique by-product of its metabolism, which can cause gut inflammation under normal gut conditions.
Published Insights into early snake evolution through brain analysis
(via sciencedaily.com) Original source Recent study sheds new light on the enigmatic early evolution of snakes by examining an unexpected source: their brains. The results emphasize the significance of studying both the soft parts of animals’ bodies and their bones for understanding how animals evolved.
Published Explosion in fish biodiversity due to genetic recycling
(via sciencedaily.com) Original source The rapid formation of 500 different species of fish in a single lake, each with specialized ecological roles, resulted from a small but genetically diverse hybrid population.
Published Timing plant evolution with a fast-ticking epigenetic clock
(via sciencedaily.com) Original source Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes
(via sciencedaily.com) Original source Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published Ultrasound may rid groundwater of toxic 'forever chemicals'
(via sciencedaily.com) Original source New research suggests that ultrasound may have potential in treating a group of harmful chemicals known as PFAS to eliminate them from contaminated groundwater.
Published Solving a sticky, life-threatening problem
(via sciencedaily.com) Original source Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published Genes fuelling antibiotic resistance in Yemen cholera outbreak uncovered
(via sciencedaily.com) Original source Scientists have identified the source of antibiotic resistance that emerged within bacteria driving the ongoing Yemen cholera epidemic.
