Firefighters are being extra cautious when they work to cut people free from wrecked vehicles these days because of the dangers found in electric...
Documents obtained by CBC News show the curiosity and confusion shared by Canadian military officials after the 2016 launch of Pokemon Go, which was sending civilians onto Department of Defence property searching for "mythical digital...
Scare stories abound but the evidence remains consistentThe past decade in British healthcare has been disappointing: improvements in life expectancy and neonatal mortality have stalled and public satisfaction with the NHS has fallen sharply.But one positive singled out in a recent review of healthcare developments was the rise of e-cigarettes use, which the article noted had given “tobacco...
Thousands of holidaymakers and locals were forced to flee to beaches in fire-ravaged southeast Australia Tuesday, as blazes ripped through popular tourist areas leaving no escape by land.
In a humming factory in Kenya's highlands, tea is hand-plucked from the fields, cured and shredded into the fine leaves that have sated drinkers from London to Lahore for generations.
The nondescript building on an industrial site near Kyoto gives little hint to the productivity inside: 30,000 heads of lettuce grow here daily, under artificial light and with barely any human intervention.
The number of people killed by a powerful storm that pummeled the central Philippines over Christmas has risen to 50, authorities said Tuesday, making it the nation's deadliest storm of 2019.
Smoke-choked Sydney was gearing up Tuesday for a huge fireworks display, kicking off a wave of New Year celebrations for billions around the world and ringing in the new decade.
Panama on Tuesday marks two decades of control over the vital interoceanic Canal following its return by the United States, but worries over weak traffic and climate change loom.
There has been no shortage of big news over the last decade. Spanning the globe, some stories were expected while others caught the world off guard. Some were so massive they were visible from space, captured through state-of-the-art imaging satellites belonging to technology company and imagery provider Maxar Technologies. Together, The Associated Press and Maxar assembled a selection of the most...
Parasites in the genus Plasmodium, which cause malaria, are transmitted to humans through bites from infected mosquitoes. The parasites manage to acclimatize to these two completely different hosts because the plasticity of their genome enables them to adapt as necessary. Scientists decided to investigate the epigenetic mechanisms behind this plasticity, in particular DNA methylation. They...
Human noroviruses, the leading viral cause of foodborne illness and acute diarrhea around the world, infect cells of the small intestine by piggybacking on a normal cellular process called endocytosis that cells use to acquire materials from their environment.
Tiny bits of DNA collected from waters off the West Coast allowed scientists to identify more species of marine vertebrates than traditional surveys with trawl nets. They also reflect environmental shifts such as unusual ocean temperatures that affect the organisms present, new research shows.
In a new study, a team born in part at the Neural Systems & Behavior course in Woods Hole tests the notion that a cell's identity can be described solely by the genes it expresses. The study, published in Proceedings of the National Academy of Sciences, advocates a more 'multimodal' approach to defining cell identity.
The region of the brain called the ventral pallidum balances signals that either excite or inhibit neurons to influence the motivation of an animal to seek pleasure or avoid pain. An imbalance skews positive vs. negative motivation and may explain behaviors associated with psychiatric disorders like depression or anxiety.
The authors conclude the review with a summary of future perspectives, in which they discuss how newly developed techniques, like the deactivated-Cas9 (dCas9) gene-expression control system, can be utilized during the course of hematopoietic differentiation of pluripotent stem cells for precise temporal control of the aforementioned master regulators to achieve functional HSCs.
Before gene therapy can be used to treat renal diseases, delivery of therapeutic genes to the kidney must become much more efficient.
NASA-NOAA's Suomi NPP satellite provided forecasters with an image of Tropical Cyclone Sarai and it showed a much weaker storm near Tonga in the South Pacific Ocean.
Visible imagery from NASA's Aqua satellite on Dec. 31, 2019 revealed that Tropical Cyclone Calvinia had moved south of the island of Mauritius in the Southern Indian Ocean.
Researchers report that accumulating amyloid protein occurred faster among persons deemed to have 'objectively-defined subtle cognitive difficulties' (Obj-SCD) than among persons considered to be 'cognitively normal,' offering a potential new early biomarker for Alzheimer's disease.
A vaccine to ward off dementia may proceed to clinical trials after successful animal testing. The US-led research is looking to develop effective immunotherapy via a dual vaccine to remove 'brain plaque' and tau protein aggregates linked to Alzheimer's disease. It is showing success in begenic mice models, supports progression to human trials in years to come.
Thermoelectric materials can convert temperature difference in a conducting solid into electrical energy, or vice versa. However, the conventional thermoelectric effect, i.e., the longitudinal Seebeck effect, meets some severe limitations in promoting its conversion efficiency. Now, scientists in Chinese Academy of Sciences have found large transverse thermoelectric effect in a topological...
Now, a Johns Hopkins Medicine research team reports it has developed and tested a relatively simple strategy for reducing the chance of parents exposing their babies in the NICU to one of the most commonly diagnosed and potentially deadly microbial scourges in a hospital: Staphylococcus aureus. The researchers detailed the positive findings from their preliminary clinical trial in the Dec. 30,...
Chinese researcher He Jiankui, who stirred up a global controversy last year when he said his experiment produced twin baby girls with gene-edited traits, has been sentenced to three years in prison and ordered to pay a $430,000 fine, the state-run Xinhua news agency reported today. He tried to show that genes could be edited to reduce vulnerability to the HIV virus, but outside experts voiced...
