Biotech company Moderna has been making some pretty promising strides in developing and testing its covid-19 vaccine. The company just announced it was working with the US National Institutes of Health to launch what will be one of the largest covid-19 vaccine trials, a phase 3 study enrolling tens of thousands of American volunteers to assess whether the vaccine could truly protect people from...
A pet cat has tested positive in England for the new coronavirus that causes COVID-19, the government said on Monday in the first confirmed case of an animal being infected with the virus in...
International scientific institutions are teaming up to save the world's largest aquatic amphibian.
The answers to today’s geometrical riddlesEarlier today I set you the following two puzzles. Here they are again, together with solutions.1. A 12cm x 12cm square piece of paper is marked as below. Continue...
The silence is unprecedented. Scientists are...
By tuning into a subset of brain waves, researchers have dramatically reduced the power requirements of neural interfaces while improving their accuracy -- a discovery that could lead to long-lasting brain implants that can both treat neurological diseases and enable mind-controlled prosthetics and machines.
Humans have a hard time identifying individual birds just by looking at the patterns on their plumage. An international study has now shown how computers can learn to differentiate individual birds of a same species.
Scientists gathered and published over 200,000 genomes from the human gut microbiome. The catalogue reveals that more than 70% of bacterial species in the human gut have never been grown in the lab. This new data resource could be extremely useful to investigate how the bacterial community in the human gut influences human health and disease.
Relaxing on the sofa or savoring a delicious meal: Enjoying short-term pleasurable activities that don't lead to long-term goals contributes at least as much to a happy life as self-control, according to new research. The researchers therefore argue for a greater appreciation of hedonism in psychology.
Researchers suggest that community-based genetic screening has the potential to efficiently identify individuals who may be at increased risk for three common inherited (CDC Tier 1) genetic conditions known to cause several forms of cancer and increased risk for heart disease or stroke.
Of 1,068 patients from 10 health centers enrolled in the study, 67.1% of those who elected to initially manage their care through antibiotics alone experienced no harmful side effects and did not later require an appendectomy by their one-year follow-up appointment. Patients in the non-operative group experienced an average of 6.6 disability days, compared to the 10.9 days in the surgery group.
A new imaging method uses the natural autofluorescence within cells to assess T cell activity. The technique could help assess T cell involvement in immunotherapies.
Flu (influenza) and pneumonia vaccinations are associated with reduced risk of Alzheimer's disease, according to new research.
Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years.
An endangered aquatic insect that lives in icy streams fed by glaciers might not mind if the water grows warmer due to climate. A new study found that mountain stoneflies can tolerate warmer water temperatures at least temporarily. In fact, they might even be stressed in their current extremely cold environments.
A sonic boom-like seismic phenomenon of supershear rupture occurred during the 2018 Palu earthquake in Indonesia. Researchers investigated the relationship between this phenomenon and the complex geometry of the Palu-Koro fault. An 'inchworm-like' pattern of repeated rupture deceleration and acceleration along the fault was detected, associated with bends in the fault trace. This slip evolution...
Scientists demonstrate a synchrotron X-ray spectroscopy-based method by which the local temperatures of metal nanoparticles can be measured under microwaves. This approach provides insight into the role that their temperature has on their catalytic performance and sheds light on how local particle heating using microwaves could become a critical strategy for improving the energy efficiency of...
A new study finds that youth docents have an overall positive effect on visitors' experiences, learning and information retention at informal learning sites -- like museums. The positive effects accrued across age groups regardless of museum type, but were most apparent in children ages 9 to 11.
Researchers have developed a novel device for single nanoparticle trapping, which has potential applications for drug discovery, disease monitoring, biomedical imaging, and more.
The oldest trees on Earth have stood for nearly five millennia, and researchers have long wondered to what extent these ancient organisms undergo senescence, physically deteriorating as they age. Plant biologist now argue that although signs of senescence in long-lived trees may be almost imperceptible to people, this does not mean that they're immortal.
Repeated activity wears on soft robotic actuators, but these machine's moving parts need to be reliable and easily fixed. Now a team of researchers has a biosynthetic polymer, patterned after squid ring teeth, that is self-healing and biodegradable, creating a material not only good for actuators, but also for hazmat suits and other applications where tiny holes could cause a danger.
The latest round of offshore wind farms to be built in the UK could reduce household energy bills by producing electricity very cheaply.
Two groups of nerve cells may serve as ''on-off switches'' for male mating and aggression, suggests a new study in rodents. These neurons appear to send signals between two parts of the brain - the back tip, or posterior, of the amygdala and the hypothalamus - that together regulate emotions including fear, anxiety, and aggression.
Animal patterns are a source of endless fascination, and now researchers have worked out how zebrafish develop their stripes.
