Shark Week is many things. First and foremost, it's a week of shark-themed documentary programming on the Discovery Channel. Now in its 33rd year, it's the longest-running cable event in history. It's the biggest audience that marine biologists and ocean conservationists get, attracting millions of viewers who might otherwise not ever think about sharks at all. It's a stage that has launched...

NASA’s InSight robotic lander has just given us our first look deep inside a planet other than Earth. More than two years after its launch, seismic data that InSight collected has given researchers hints into how Mars was formed, how it has evolved over 4.6 billion years, and how it differs from Earth. A set of three new...
Researchers are pushing organ-on-a-chip devices to new levels that could change the way clinicians approach cancer treatment, particularly ovarian cancer.
Inexpensive and convenient devices such as silicone wristbands can be used to yield quantitative air quality data, which is particularly appealing for periods of susceptibility such as pregnancy.
Risk of reinfection with Delta may be 46% greater than with the Alpha variant, national testing data findsCoronavirus – latest updatesSee all our coronavirus coveragePublic Health England has upgraded its risk assessment of the Delta variant after national testing data revealed it is more likely to cause reinfections than the Alpha variant, which was first identified in Kent.The health...
Researchers have developed two solutions with potential to overcome a key clinical limitation of immune cell therapies.
The late Alex Trebek, who began his career at the CBC and went on to host the iconic game show Jeopardy for 37, is being honoured with a grant program for emerging Canadian explorers, scientists, educators and...
Recently, a research group led by Prof. Yuan Kaijun and Prof. Yang Xueming from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences revealed strong isotope effects in photodissociation of the water isotopologue (HOD) using the Dalian Coherent Light Source.
When experiencing the ups and downs of a virtual roller coaster ride, people who get migraine headaches reported more dizziness and motion sickness than people who do not get migraines, according to a new study.
There are many reasons that an intranasal vaccine against the SARS-CoV-2 virus would be helpful in the fight against COVID-19 infections, immunologists write in a new article.
Long thought of as a generic alarm system, the locus coeruleus may actually be a sophisticated regulator of learning and behavior, according to a new review.
Coffee shops and casual restaurants are an important part of American life. Even beyond the food and drinks they sell, they offer us a place to use the restroom or rest our feet while we're out and about, and they provide internet access to those on the go, those in need of a temporary office, or those who don't have an internet connection at home. Many of us take for granted that a nearby...
The costs of dealing with the coronavirus pandemic have forced Mexican archaeologists to re-bury a unusual find that combined colonial and pre-Hispanic features.

As the SARS-CoV-2 virus that causes COVID-19 continues to evolve, immunologists and infectious diseases experts are eager to know whether new variants are resistant to the human antibodies that recognized initial versions of the virus. Vaccines against COVID-19, which were developed based on the chemistry and genetic code of this initial virus, may confer less protection if the antibodies they...
Electromagnetic (EM) waves in the terahertz (THz) regime contribute to important applications in communications, security imaging, and bio- and chemical sensing. Such wide applicability has resulted in significant technological progress. However, due to weak interactions between natural materials and THz waves, conventional THz devices are typically bulky and inefficient. Although ultracompact...
In a wealth and longevity study to incorporate siblings and twin pair data, researchers analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.
New research by an Executive PhD Research student at the Business School (formerly Cass) outlines how elderly patients with neurological conditions are significantly more likely to develop delirium shortly after they are hospitalised, and those admitted on Sunday and Tuesday are more likely to develop the disorder.
Researchers have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain's 'feel good' chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for reward.
Humid tropical forests, vital in global efforts to limit rising temperatures, are under threat as a result of changes in land use and climate. Now, researchers have developed a new way to keep tabs on the vulnerability of these forests on a global scale using satellite data called the tropical forest vulnerability index (TFVI).
