Best Heart Rate Monitors (2026): Polar, Coros, Garmin

Published by skeptic

FAQS We tested and recommend all of the heart rate monitors below, which do a pretty impeccable job. But what do all these terms mean? Heart rate zones: If someone tells you they’ve been doing 80/20 training, they’ve been doing heart rate zone-based workouts. Heart rate zones are an easy way to break down your range of effort during exercise. Zones go from 1 to 5, with 5 indicating working at 90 to 100 percent of your maximum heart rate. Zone 2 represents training at 60 to 70 percent of maximum heart rate and represents light training. 80/20 training is intended to build endurance and means that 80 percent of your runs should be in Zone 2. If your heart rate monitor doesn’t tell you your zone, you can calculate it using Polar’s simple tool. Maximum heart rate: Some monitors can inform you of your maximum heart rate, which is the number of beats your heart can reach during exercise. This is useful for knowing when you’re training at peak intensity and can be used …

How to convey amounts of snow to Canadians: use polar bears

How to convey amounts of snow to Canadians: use polar bears

Feedback is New Scientist’s popular sideways look at the latest science and technology news. You can submit items you believe may amuse readers to Feedback by emailing feedback@newscientist.com A shedload of bears Following the use of golden retrievers as a unit of ice mass, Feedback has found our inbox filling up with more examples of unconventional and often unintuitive units of measurement. Craig Downing, who self-identifies as “one of those readers that opens every issue from the back” and therefore gets top billing in this column, tells us of the Rideau canal running through his home city of Ottawa, Canada. The canal freezes every winter, becoming the world’s largest skating rink by area. However, the rink must be meticulously cleared of snow to ensure a smooth surface. Hence the statement by the canal’s managers, the National Capital Commission, that Craig was emailed. “For every 1 cm of snowfall, our crews move 125,000 kg of snow off the Skateway. That’s equivalent to 450 polar bears!” Craig is baffled. “I usually think of snowfall mass and volume …

Snow maps see Britain hit by 8 day Polar blitz – 25 cities affected | Weather | News

Published by Sam Flores

The UK is braced for an eight-day barrage of snowfall in the coming weeks. According to the last weather maps from WX Charts, 25 cities in Britain will be hit by snowfall between early in the morning on Tuesday, March 10 and the afternoon of Tuesday, March 17. The maps show the snow arriving at 6am on March 10, with flurries forecast in parts of North Wales, North West England, Northern Ireland and across large parts of Scotland. Up to 7cm could settle in the Lake District while central Scotland could see 11cm of snow. Meanwhile, the Met Office is expecting “unsettled conditions” across the UK at this time. On Sunday, March 15, the maps show widespread snowfall across the north of England. Cities including Newcastle and Carlisle can expect between 2cm and 4cm of the white stuff. Meanwhile, Northern Ireland can expect between 1cm and 2cm of snow to land at 6am on the same day. The snow will once again be heaviest in Scotland, with western areas forecast to see up to 26cm …

For 21 years, conservation nonprofit Polar Bears International has celebrated these vulnerable bears with a day of conservation action and learning. Right now, polar bear moms are tending to their newborn cubs across the Arctic, and preparing to emerge from their dens to begin raising their young on the ice. This first spring represents the most at-risk time of a polar bear’s life. On average, fewer than half of cubs will reach adulthood.  One person who has seen that crucial time in a young bear’s life first-hand is award-winning wildlife photographer Daniel J. Cox. He has been photographing nature in all of its glory for over 40 years and helped create the Arctic Documentary Project and collaborates with Polar Bears International.  Polar Bear mother with cubs with one climbing on to her back for an easy ride.

In Svalbard, where sea ice is vanishing faster than anywhere else, polar bears remain healthy

In Svalbard, where sea ice is vanishing faster than anywhere else, polar bears remain healthy

Published by Sam Flores

A polar bear in Svalbard, October 10, 2024. TRINE LISE SVIGGUM HELGERUD/INSTITUT POLAIRE NORVÉGIEN Footage shot in the Arctic by scientists shows a polar bear feasting on a seal atop a drifting slab of sea ice. In another video, a female bear crosses a vast, frozen expanse, trailed by her two cubs. Elsewhere, a male bear roams through the snow. These mammals appear healthy – far from the images of emaciated bears that have sparked concern in recent years. In the far north, Svalbard, the Norwegian archipelago, is a paradox. Climate change has warmed the region faster than anywhere else on Earth, and its sea ice is shrinking more rapidly than in any other ice-bound area. Yet, the physical condition of adult polar bears has not worsened over the past 25 years. In fact, it improved after 2000, according to a study published on Thursday, January 29, in Scientific Reports, based on long-term monitoring in the Barents Sea. This may be only a respite before an expected decline. Researchers analyzed the physical condition of 770 …

Svalbard polar bears are doing surprisingly well (for now)

Svalbard polar bears are doing surprisingly well (for now)

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. The Arctic’s polar bears (Ursus maritimus) are often the poster species for the perils of climate change. Threatened by rapidly dwindling sea ice and habitat loss as the world warms, over two-thirds of polar bears could go extinct by 2050. Despite the dire situation, polar bear populations on the Norwegian archipelago of Svalbard have improved. The reason could be hidden beneath their fur and in their surroundings. The findings are detailed in a study published today in the journal Scientific Reports. The Svalbard archipelago is located halfway between the northern coast of Norway and the North Pole. The remote region is home to a seed vault, about 2,100 people, and some unique wildlife—including the world’s smallest reindeer. There are also an estimated 3,000 polar bears and about 300 remain on Svalbard year-round, while others migrate. Internationally, polar bears have been protected from hunting since 1973, so their primary threats are increased temperatures due to climate change, habitat and food …

Polar bears are getting fatter in the fastest-warming place on Earth

Polar bears are getting fatter in the fastest-warming place on Earth

Published by skeptic

Researchers tracked the body condition of polar bears in Svalbard Jon Aars, Norsk Polarinstitutt Polar bears have been getting fatter even as sea ice disappears in Norway’s Svalbard archipelago, the fastest-warming place on Earth – but scientists don’t expect the good times to last. The northern Barents Sea, which stretches between Svalbard and Russia’s Novaya Zemlya in the Arctic Ocean, has been heating up seven times faster than the globe as a whole. The sea ice around Svalbard lasts two months less in winter and spring than it did two decades ago. Bears now have to swim 200 to 300 kilometres between hunting grounds on the ice and snow dens on the islands where they give birth. But the average size and weight of the Svalbard bears have increased since 2000, a finding that surprised Jon Aars at the Norwegian Polar Institute, who led the study. “We should think about this as good news for Svalbard,” he says. “But if you want bad news, you can just go and look somewhere else where you have …

EFREM LUKATSKY/AP The Russian military is taking advantage of the recent Arctic cold snap that has struck Ukraine to intensify its airstrikes’ impact on major urban centers’ power systems. About 70% of Kyiv was left without electricity on Tuesday, January 13, according to Ukrenergo, the state-owned power grid operator, after another massive Russian air attack the night before.
