To make organoids grow faster, give them a squeeze, suggests a new study, which finds compressing cells, and crowding their contents, can coax them to grow and divide. The results may lead to faster way to grow artificial organs.
Trees and lawns beat the heat
- ScienceDaily
- 20/10/13 23:50
As climate change pushes many cities towards dangerous temperatures, planners are scrambling to mitigate excessive heat. One strategy is to replace artificial surfaces with vegetation cover. In water-limited regions, municipalities have to balance the benefit of cooler temperatures with using precious water for irrigation. A new study will make those decisions easier for the semi-arid Salt Lake...

Seaweed may be the solution to our plastic crisis. A London startup is making edible packaging out of it.
The plastic-like seaweed packaging made by Notpla is biodegradable within six weeks, compared to hundreds of years for synthetic...
Facebook greatest source of Covid-19 disinformation, journalists say
International survey nominates social media giant as worst offender, ahead of elected officialsThe majority of journalists covering the pandemic say Facebook is the biggest spreader of disinformation, outstripping elected officials who are also a top source, according to an international survey of journalism and Covid-19.The social media platform, which announced this week it was updating its hate...

- 20/10/13 22:44
The American pika is a charismatic, diminutive relative of rabbits that some researchers say is at high risk of extinction due to climate change. A new review finds that the American pika is far more resilient in the face of warm temperatures than previously believed.
Possible safety issue spurs pause of COVID-19 antibody study
Independent monitors have paused enrollment in a study testing the COVID-19 antiviral drug remdesivir plus an experimental antibody therapy being developed by Eli Lilly that’s similar to a treatment President Donald Trump recently received. Lilly confirmed Tuesday that the study had been paused “out of an abundance of caution” and said safety is its top concern. The experimental drugs are...
NASA announces eight-nation space coalition under 'Artemis Accords'
NASA announced on Tuesday that eight countries have signed an international agreement called the Artemis Accords that outlines the principles of future exploration of the Moon and beyond.
Foreign election interference: A global response
The increasing threat of foreign interference in elections has driven six nations to take similar approaches to combat this pervasive threat. A review of the details to their responses brings out valuable differences and insights. These are presented in a forthcoming special issue of the peer-reviewed Election Law Journal.
American Pikas show resiliency in the face of global warming
The American pika is a charismatic, diminutive relative of rabbits that some researchers say is at high risk of extinction due to climate change. Pikas typically live in cool habitats, often in mountains, under rocks and boulders. Because pikas are sensitive to high temperatures, some researchers predict that, as the Earth's temperature rises, pikas will have to move ever higher elevations until...
Cover crop could solve weed problems for edamame growers
For vegetable growers, weeds can mean lost income from reduced yield and foreign plant matter contaminating the harvest. But for many crops, particularly vegetable legumes, weed management options are very limited.
NASA sees Tropical Storm Nangka soaking Hainan Island
Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Nangka's rainfall rates as the storm soaked Hainan Island, China early on Oct. 13 (EDT).
NASA animation tracks the end of Tropical Storm Delta
NASA's Terra satellite obtained visible imagery as Tropical Storm Delta made landfall in Louisiana and moved northeastward soaking the U.S. southeast and Mid-Atlantic states.
Zoo scientists revive cells from 40-year deep freeze to clone endangered horse
Kurt looks and acts like any other young horse. He scampers and strides on springy legs, testing their strength. When it's time to recharge, he nuzzles up to his mother for some nourishing milk.
Mathematical tools predict if wave-energy devices stay afloat in the ocean
Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
Enzyme conformation influences the performance of lipase‐powered nanomotors
A study by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), the Universidad Complutense (UCM), Universidad de Girona (UdG), and the Institute for Bioengineering of Catalonia (IBEC), working together with other international centers, has overcome one of the key hurdles to the use of nanorobots powered by lipases, enzymes that play essential roles in digestion by...
New global temperature data will inform study of climate impacts on health, agriculture
A seemingly small one-to-two degree change in the global climate can dramatically alter weather-related hazards. Given that such a small change can result in such big impacts, it is important to have the most accurate information possible when studying the impact of climate change. This can be especially challenging in data sparse areas like Africa, where some of the most dangerous hazards are...

Astronaut Kate Rubins is using NASA's last currently contracted Soyuz seat for a ride to the space...
How psychological ownership can enhance stewardship for public goods
How can consumers be encouraged to take better care of public goods and resources? That's the question posed in a new research paper co-authored by Collen P. Kirk, D.P.S., associate professor of marketing at New York Institute of Technology, in the Journal of Marketing.
New method uses noise to make spectrometers more accurate
Optical spectrometers are instruments with a wide variety of uses. By measuring the intensity of light across different wavelengths, they can be used to image tissues or measure the chemical composition of everything from a distant galaxy to a leaf. Now researchers at the UC Davis Department of Biomedical Engineering have come up a with a new, rapid method for characterizing and calibrating...

Technique to recover lost single-cell RNA-sequencing information helps evaluate cell health
Sequencing RNA from individual cells can reveal a great deal of information about what those cells are doing in the body. MIT researchers have now greatly boosted the amount of information gleaned from each of those cells, by modifying the commonly used Seq-Well technique.
