Epigenetic changes help cells adapt to low oxygen levels, study reveals
Researchers at Karolinska Institutet have discovered how cells can adjust their gene activity to survive when oxygen runs low. The study, published in Nature Cell Biology, reveals that cells use a previously unknown mechanism to control which proteins are produced—and how quickly. ⌘ Read more

Southern Ocean’s low-salinity Antarctic waters continue absorbing CO₂ despite climate model predictions
Climate models suggest that climate change could reduce the Southern Ocean’s ability to absorb carbon dioxide (CO2). However, observational data actually shows that this ability has seen no significant decline in recent decades. ⌘ Read more

Follow-up observations by Webb confirm GRB 250702B is most energetic cosmic explosion ever recorded
Considering the immense size of the universe, it’s no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it’s challenging what we thought we knew about how stars die. ⌘ Read more

‘Less and less sea ice’: Brazil woman sails solo through Arctic
Brazilian navigator Tamara Klink told AFP she encountered “very little” sea ice on her solo sail through the Northwest Passage—a rare feat that would have been impossible without an icebreaker ship three decades ago. ⌘ Read more

Time crystals could power future quantum computers
A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel Laureate in Physics, proposed quantum systems––like groups of particles––could construct themselves in the same way, but in time instead of space. He dubbed such systems time crystals, defining them by their lowest possible energy state, which perpetually repeats movements without external energy input. Time crystals were experimentall … ⌘ Read more

Engineers solve the sticky-cell problem in bioreactors and other industries
To help mitigate climate change, companies are using bioreactors to grow algae and other microorganisms that are hundreds of times more efficient at absorbing CO2 than trees. Meanwhile, in the pharmaceutical industry, cell culture is used to manufacture biologic drugs and other advanced treatments, including lifesaving gene and cell therapies. ⌘ Read more
