Supermassive black hole appears to grow like a baby star      (via sciencedaily.com)     Original source 

Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating, magnetic wind that they believe is helping a galaxy's central supermassive black hole to grow. The swirling wind, revealed with the help of the ALMA telescope in nearby galaxy ESO320-G030, suggests that similar processes are involved both in black hole growth and the birth of stars.

Changing climate will make home feel like somewhere else      (via sciencedaily.com)     Original source 

The impacts of climate change are being felt all over the world, but how will it impact how your hometown feels? An interactive web application allows users to search 40,581 places and 5,323 metro areas around the globe to match the expected future climate in each city with the current climate of another location, providing a relatable picture of what is likely in store.

Scientists devise algorithm to engineer improved enzymes      (via sciencedaily.com)     Original source 

Scientists have prototyped a new method for 'rationally engineering' enzymes to deliver improved performance. They have devised an algorithm, which takes into account an enzyme's evolutionary history, to flag where mutations could be introduced with a high likelihood of delivering functional improvements. Their work could have significant, wide-ranging impacts across a suite of industries, from food production to human health.

Creation of a power-generating, gel electret-based device      (via sciencedaily.com)     Original source 

A team of researchers has developed a gel electret capable of stably retaining a large electrostatic charge. The team then combined this gel with highly flexible electrodes to create a sensor capable of perceiving low-frequency vibrations (e.g., vibrations generated by human motion) and converting them into output voltage signals. This device may potentially be used as a wearable healthcare sensor.

Titan's lakes may be shaped by waves      (via sciencedaily.com)     Original source 

Geologists studied Titan's shorelines and showed through simulations that coastlines of the moon's methane- and ethane-filled seas have likely been shaped by waves. Until now, scientists have found indirect and conflicting signs of wave activity, based on Cassini images of Titan's surface.

At least one in four US residential yards exceed new EPA lead soil level guideline      (via sciencedaily.com)     Original source 

Roughly one in four U.S. households have soil exceeding the new U.S. Environmental Protection Agency's lead screening levels of 200 parts per million (ppm), halved from the previous level of 400 ppm, a new study found. For households with exposure from multiple sources, the EPA lowered the guidance to 100 ppm; nearly 40% of households exceed that level, the study also found.

Jupiter's great red spot is not the same one Cassini observed in 1600s      (via sciencedaily.com)     Original source 

Jupiter's iconic Great Red Spot has persisted for at least 190 years and is likely a different spot from the one observed by the astronomer Giovanni Domenico Cassini in 1665, a new study reports. The Great Red Spot we see today likely formed because of an instability in the planet's intense atmospheric winds, producing a long, persistent atmospheric cell, the study also finds.

Wooden surfaces may have natural antiviral properties      (via sciencedaily.com)     Original source 

Viruses, including the coronavirus that causes COVID-19, can get passed from person to person via contaminated surfaces. But can some surfaces reduce the risk of this type of transmission without the help of household disinfectants? Wood has natural antiviral properties that can reduce the time viruses persist on its surface -- and some species of wood are more effective than others at reducing infectivity.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
