A team of medics hiked in the mountains for hours to take supplies to the small village of NakidaSee all our coronavirus coverageTo reach Nakida village in the highlands of Fiji, Dr Losalini Tabakei and her colleagues hiked for hours, up and down mountains, through forests, down muddy slopes, across rivers and along treacherous ridges with steep slopes of bamboo forest on either side.Their...
The space cemetery, named for the fictional captain in 20,000 Leagues Under the Sea, is where the International Space Station is likely to end upAt the furthest point from any landmass on earth, and 4km under the sea, lies the space cemetery.When their outer space journeys come to an end, old satellites, rocket parts and space stations are sent to this desolate spot in the Pacific Ocean to rest on...
As the remnants of Hurricane Ida passed over the northeast Wednesday night, dumping a record-shattering 3.15 inches of rain on New York City in a single hour, water began to pour into the city’s subways. The system flooded in 46 locations and the MTA cut service across all lines overnight. Rescue operations had to be carried out to reach those unlucky enough to be caught in at least 15...
Researchers have developed a new imaging technique capable of visualizing the dynamically changing structure of dendritic spines with unprecedented resolution. By combining two cutting-edge types of microscopies, scientists now have the tools necessary to unravel the ultrastructural complexities of spines during the process of synaptic plasticity.
Analysis: The JCVI would not back vaccination of all 12 to 15-year-olds, but the impact on schools will now have to be consideredCoronavirus – latest updatesSee all our coronavirus coverageIt was, the scientists said, a very finely balanced decision. On the one hand, Covid vaccines undoubtedly help to reduce infection and illness. On the other, Covid vaccines – like every other vaccine in...
Extremely premature infants are at a high risk for brain damage. Researchers have now found possible targets for the early treatment of such damage outside the brain: Bacteria in the gut of premature infants may play a key role. The research team found that the overgrowth of the gastrointestinal tract with the bacterium Klebsiella is associated with an increased presence of certain immune cells...
Individuals who are hospitalized during pregnancy due to sepsis have higher odds of complications surrounding childbirth, according to a new study. The study found that pregnancies complicated by sepsis were associated with an increased risk of cesarean delivery, postpartum hemorrhage and preterm delivery, highlighting the risk of any severe infection during pregnancy.
Social vulnerabilities of coastal communities and their reliance on blue carbon ecosystem services may be improved by addressing three major factors, according to a new study.
The most significant Arctic oasis is susceptible to climate change -- researchers say that global warming is threatening the region's ecosystem, and predict that the oasis will cease to exist.
Scientists have purified and identified an attractant for crop-infecting root-knot nematodes from flaxseeds. Their experiments revealed that rhamnogalacturonan-I (RG-I), a flaxseed cell wall component, can attract root-knot nematodes. The linkages between rhamnose and L-galactose are essential for the attraction.
Researchers have developed a deep learning-based method that can predict the possible onset of Alzheimer's disease from brain images with an accuracy of over 99 percent. The method was developed while analyzing functional MRI images obtained from 138 subjects and performed better in terms of accuracy, sensitivity and specificity than previously developed methods.
Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists solves this problem by letting quantum computers check each other's work.
Neuroscientists have developed a statistical framework that rigorously describes the brain state changes that patients experience under ketamine-induced anesthesia.
Scientists have found that tiger sharks, often considered a solitary nomadic species, are social creatures, having preferences for one another.
Subscription-based payment models (SBPM), a novel approach in which states contract exclusively with a single manufacturer to supply prescriptions at a reduced price, could increase access to these life-saving treatments, according to a new study. In a SBPM, states pay reduced per prescription prices for medications until a certain utilization threshold. After this threshold, the cost of...
How do we make decisions about a situation we have not encountered before? New work shows that we can solve abstract problems in the same way that we can find a novel route between two known locations -- by using an internal cognitive map.
Carthamin's usage as dye dates back to ancient Egypt. But scientists only discovered its chemical structure in 2019. Now, a group of researchers has identified the genes required for the biosynthesis of carthamin.
Researchers use statistical methods on video data to quantitatively determine the biomechanical techniques correlated with successful judo throws. This work may assist in developing supervised or self-guided training routines.
A simple mechanism could underlie the growth and self-replication of protocells -- putative ancestors of modern living cells -- suggests a new study. Protocells are vesicles bounded by a membrane bilayer and are potentially similar to the first unicellular common ancestor (FUCA). On the basis of relatively simple mathematical principles, the proposed model suggests that the main force driving...
Bioengineers have repurposed a 'non-working' CRISPR system to make a smaller version of the genome engineering tool. Its diminutive size should make it easier to deliver into human cells, tissues and the body for gene therapy.
On Aug. 14, 2021, a small near-Earth asteroid (NEA) designated 2021 PJ1 passed our planet at a distance of over 1 million miles (about 1.7 million kilometers). Between 65 and 100 feet (20 and 30 meters) wide, the recently discovered asteroid wasn't a threat to Earth. But this asteroid's approach was historic, marking the 1,000th NEA to be observed by planetary radar in just over 50 years.
In eastern Belgium, an abandoned highway is almost completely buried under kilometres of piled-up rubbish: crushed refrigerators, splintered furniture, torn curtains, twisted metal, stuffed toys, defunct electronics and shards of glass.
The role of climate change in New York's deadly flash floods and the city's creaking infrastructure were under the spotlight Friday after torrential rains left at least 47 people dead across the US northeast.
For the past 20 years, it's been Les Shaw's mission to unravel the mysteries of drug-resistant bacterial pathogens.
A joint project team in Japan have started field testing for Asset-Based Lending (ABL) applicability at Kuroshima Sakura Farm in Kuroshima island, Okinawa prefecture, which is known for the world-famous "Wagyu" cattle industry. The ABL approach employs cattle behavior monitoring system "PETER" developed by the project team aimed for labor-saving grazing management using edge-AI and LPWA (Low...
What started as a casual dinner conversation between two very different researchers in 2016—one a data scientist and engineer, the other an expert in economic models—has since turned into a journal article quantifying the effects of the "beauty premium," the notion that those who are more physically attractive tend to have a greater income.
Floods killed at least two dozen people as Hurricane Ida swept through New York, New Jersey, and Pennsylvania on the night of September 1. This devastation is on top of the 13 who died and the million who lost power when the storm hit Louisiana, Mississippi, and Alabama last weekend. As the storm moved up the East Coast, New York City was hit particularly hard. Over three inches of rain fell in...
House in southern France yielded find of outstanding wall paintings dating from 1st century BCOn the right bank of the Rhône in the Provençal town of Arles, the Roman-built House of the Harpist is being hailed as a remarkable record of ancient architecture and interior decoration.Now, experts have opened their workshop to reveal their painstaking attempts to piece together the vast jigsaw of...
The UN weather agency says the world — and especially urban areas — experienced a brief, sharp drop in emissions of air pollutants last year amid lockdown measures and related travel restrictions put in place over the coronavirus...
