Evade

The International Space Station had to cancel yet another spacewalk. This time, however, the walk was canceled due to the ISS having to evade Russian space debris for at least the second time this year. The space station, which is currently slated to be decommissioned in the 2030s, has found itself experiencing issues caused by Russian spacecraft several times in 2022. The first time that the ISS had to swerve to avoid Russian space debris this year was back in June. An anti-satellite test from 2021 caused that…

Thanks to its geothermally active location, the town of Kusatsu, Gunma Prefecture (in the background of this image), is one of Japan’s most popular onsen (hot springs) destinations.

A team at the University of Tokyo has found that the ratio of atoms…

Each colored ribbon represents a DNA barcode. As the tumor evolves, some cancer cells come to dominate the tumor, shown by the orange and red ribbons. This shows these cancer cells have a pre-existing ability to escape the immune system and can carry on growing, even after treatment.

Over the course of evolution, immense megafauna have roamed the lands or swum in the seas. The growth of these creatures early in their life is typically quite rapid. It has to be. They need to grow fast or be eaten. Extensive studies on megafauna have addressed the unique challenges of supporting and moving such massive bodies. But the greatest and largely ignored obstacle to extreme growth for both terrestrial and aquatic megafauna may involve the rapid development of their nervous system. Unlike all other cell types,…

Ether has hugely outperformed bitcoin since both cryptocurrencies formed a bottom in June 2022. Ether's superior gains have come as investors anticipate a major upgrade to the ethereum blockchain called "the merge."Yuriko Nakao | Getty ImagesRussian President Vladimir Putin could use cryptocurrencies to evade U.S. and other sanctions launched against the Kremlin for its unprovoked invasion of Ukraine, a Treasury official told lawmakers Tuesday."Yes, senator, that's possible," Elizabeth Rosenberg, Treasury's assistant…

Prescriptions for Pfizer’s blockbuster drug Paxlovid have skyrocketed in recent weeks. That’s good news for many COVID-19 patients, as the pill has been proven to reduce severe disease from SARS-CoV-2 infections. But a bevy of new lab studies shows the coronavirus can mutate in ways that make it less susceptible to the drug, by far the most widely used of the two oral antiviral drugs authorized to treat COVID-19 in the United States. Researchers have found some of those mutations…

An unexpected potential solution has now emerged in medicines that are not designed to fight cancer, but rather to target proteins that regulate a cell’s circadian rhythm.An international team…

Anna’s hummingbird (Calypte anna). New research shows that hummingbirds would struggle to cope if climate changes drives them to much higher elevations.Any animal ascending a mountain experiences a double whammy of difficulties: the air gets thinner while it also becomes colder, which is particularly problematic for creatures striving to keep warm when less oxygen is available. For tiny animals with the highest-octane lives, such as hovering hummingbirds, the challenges of migrating to higher levels to evade climate…

Citizens in authoritarian regimes worldwide are managing to evade internet controls in an attempt to get uncensored information. Russians are using virtual private networks to circumvent internet crackdowns following the invasion of Ukraine. In North Korea, some users can sidestep government restrictions on smartphones. It’s part of a growing struggle between many governments and their citizens to control information flowing through the internet. “Mobile users would have to use the same techniques as desktop users,…
