A new study has confirmed a long-held assumption: that orcas take just one breath between dives. The researchers used drone footage and biological data from tags suction-cupped to 11 northern and southern resident killer whales off the coast of B.C. to gather information on the animals' habits. Confirming orcas take only one breath between dives allowed the researchers to calculate how many litres of oxygen adults and juveniles consume per... Read more ›

Scientists uncover why cancer patients with ARID1A gene mutations are more likely to respond to immunotherapy, discovering ARID1A mutations invite cancer-fighting immune cells into tumors by triggering an antiviral-like response. Their findings could help improve cancer care and drug development for many cancer types, including endometrial, ovarian, colon, gastric, liver, and pancreatic cancers. Read more ›

'Dust clouds' at the bottom of the deep sea, that will be created by deep-sea mining activities, descend at a short distance for the biggest part. Yet, a small portion of the stirred-up bottom material remains visible in the water at long distances. Read more ›

John Milton's handwritten annotations have been identified in a copy of Raphael Holinshed's Chronicles (1587), a vital source of inspiration for the Paradise Lost poet. The discovery makes this one of only three known books to preserve Milton's handwritten reading notes, and one of only nine books to have survived from his library. Read more ›

At present, there is no specific active substance against hepatitis E. As the disease kills 70,000 people every year, researchers are actively searching for one. A team may have found what they're looking for. The researchers showed that the compound K11777 prevents host cells from helping the virus out of its shell by cleaving the viral capsid. This means it can no longer infect cells. Read more ›

Researchers have developed a new method that can lead to significant energy savings in buildings. The team identified 28 major heat loss regions in a multi-unit residential building with the most severe ones being at wall intersections and around windows. A potential energy savings of 25 per cent is expected if 70 per cent of the discovered regions are fixed. Read more ›

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths. Read more ›

A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America. Moose populations have been dwindling for years across the country due to many contributing factors, but new research has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.

Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star. Read more ›

Everyone experiences aging in their own way, and factors such as genetics, lifestyle and environment play a role in this process. Some individuals reach the age of 90 or even 100 in good health, without medications or brain disease. But how do these individuals maintain their health as they age? Read more ›
