Predator interactions chiefly determine where Prochlorococcus microbes thrive
Prochlorococcus are the smallest and most abundant photosynthesizing organisms on the planet. A single Prochlorococcus cell is dwarfed by a human red blood cell, yet globally the microbes number in the octillions and are responsible for a large fract.....»»
Identifying the fish species present in a river based on traces of their DNA
As they swim around, fish leave DNA fragments behind them, for example via their skin or their excrements. Once collected and analyzed, these indicators allow scientists to determine all the species present in the environment. What's more, the method.....»»
A deep-learning framework for drug–drug interactions and drug–target interactions prediction
Exploring the biomedical interactions for chemical compounds and protein targets is crucial for drug discovery. Determining these drug–drug interactions (DDI) and drug–target interactions (DTI) not only reveals the potential synergistic effects o.....»»
Much effort, little prey: Poor foraging success drives bats away from cities
While some wildlife species thrive well in cities, it's harder for large, insectivorous bat species to find enough food. To get their fill, city-dwelling common noctules (Nyctalus noctula) have to hunt longer than their rural counterparts and yet the.....»»
Sulfur-cycling microbes could lead to new possibilities in river-wetland-ocean remediation
Nutrient cycles such as the carbon, nitrogen, phosphorous and sulfur cycles are critical processes that free up elements essential to life by recycling them through our water, air, and soil. Sulfur, specifically, is an integral element in producing a.....»»
Astronomers determine the age of three mysterious baby stars at the heart of the Milky Way
Through analysis of high-resolution data from a 10-meter telescope in Hawaii, researchers at Lund University in Sweden have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars proved to be unusually y.....»»
A method to resolve quantum interference between photoionization pathways with attosecond resolution
The field of attosecond physics was established with the mission of exploring light–matter interactions at unprecedented time resolutions. Recent advancements in this field have allowed physicists to shed new light on the quantum dynamics of charge.....»»
HP Smart Tank 5101 review: when paper jams hurt
We tested HP's Smart Tank 5101, an affordable all-in-one inkjet tank printer, to determine its long-term value and ease of use......»»
An anomalous relativistic emission arising from the intense interaction of lasers with plasma mirrors
Interactions between intense laser pulses and plasma mirrors have been the focus of several recent physics studies due to the interesting effects they produce. Experiments have revealed that these interactions can generate a non-linear physical proce.....»»
New model allows for learning and prediction of microbial interactions
A tiny but prolific world of microbes encompasses everything around us, both inside and out. Microbiomes, which are comprised of diverse communities of microbes, play a pivotal role in shaping human health, yet the intricacies of how different microb.....»»
BBC BASIC remains a remarkable learning tool, and now it’s available everywhere
42 years later, there's still work to be done in spreading the BBC Micro gospel. Enlarge / A vintage 1981 BBC Micro computer. Fun fact: it was rather tricky to determine which version of BBC Basic a Micro was actually running. (c.....»»
Scientists determine how to properly feed rainbow trout
Scientists from the RUDN University and colleagues from Iran have determined the optimal dosage of a popular dietary supplement for rainbow trout. Exceeding it not only negates a positive effect, but can cause harm to the health of the fish. Results.....»»
Researchers design smaller, more cost-efficient electron cryo-microscope
Researchers have designed a new electron cryo-microscope that is a fraction of the size and cost of current alternatives and used it to determine 11 atomic structures. The breakthrough aims to slash the cost of running electron cryo-microscopy (cryoE.....»»
Landscape dynamics determine the evolution of biodiversity on Earth, research reveals
Movement of rivers, mountains, oceans and sediment nutrients at the geological timescale are the central drivers of Earth's biodiversity, research published in Nature has revealed......»»
Minimalist or maximalist? The life of a microbe a mile underground
If you added up all the microbes living deep below Earth's surface, the amount of biomass would outweigh all life within our oceans......»»
Having a single parent doesn"t determine your life chances. Data shows poverty is far more important
Numerous research studies have suggested that children from a single-parent family are worse off than those who have two parents at home. These findings chime with decades of stigma that have painted coming from a single-parent home as undesirable......»»
From underground detectors to cosmic secrets: Exploring dark matter-nucleon interactions
In a new study, scientists report results from the PandaX-4T experiment, setting stringent limits on dark matter–nucleon interactions using low-energy data and the Migdal effect, ruling out significant parameter space for a thermal relic dark-matte.....»»
New constraints on the presence of ultralight dark matter in the Milky Way
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental meth.....»»
The "dahliagram": An interdisciplinary tool to enable exploration of human-environment interactions
Spurred by the current climate crisis, there has been heightened attention within the scientific community in recent years to how past climate variation contributed to historic human migration and other behaviors......»»
Researchers predict climate change-driven reduction in beneficial plant microbes
Bacteria that benefit plants are thought to be a critical contributor to crops and other ecosystems, but climate change may reduce their numbers, according to a new study by an international team of researchers. They have published their findings in.....»»
Using tiny traps to study protein interactions can provide new knowledge about difficult-to-treat diseases
Proteins that form clumps occur in many difficult-to-treat diseases, such as ALS, Alzheimer's, and Parkinson's. The mechanisms behind how the proteins interact with each other are difficult to study, but now researchers at Chalmers University of Tech.....»»
