And Then There Were Three: NASA Shuts Down More Voyager 2 Science Instruments

Universe Today Feed - Wed, 03/05/2025 - 2:37am

In an effort to conserve Voyager 2's dwindling energy and extend the spacecraft's mission, NASA has shut down another of its instruments. They did it with the Plasma Spectrometer in October 2024, and it won't be the last. In March, Voyager 2's Low-Energy Charged Particle instrument will be powered down.

New computer vision system can guide specialty crops monitoring

Computers and Math from Science Daily Feed - Tue, 03/04/2025 - 1:44pm
Soilless growing systems inside greenhouses, known as controlled environment agriculture, promise to advance the year-round production of high-quality specialty crops, according to an interdisciplinary research team. But to be competitive and sustainable, this advanced farming method will require the development and implementation of precision agriculture techniques. To meet that demand, the team developed an automated crop-monitoring system capable of providing continuous and frequent data about plant growth and needs, allowing for informed crop management.

NASA's Hubble finds Kuiper Belt duo may be trio

Space and time from Science Daily Feed - Tue, 03/04/2025 - 11:35am
The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, and has most recently been popularized in the novel and television show '3 Body Problem.' There's no problem, however, with what a team of researchers say is likely a stable trio of icy space rocks in the solar system's Kuiper Belt.

Consumer devices can be used to assess brain health

Computers and Math from Science Daily Feed - Tue, 03/04/2025 - 11:34am
Technology is changing how physicians think about assessing patients and, in turn, how patients expect to be able to measure their own health. Apps designed for smartphones and wearable devices can provide unique insights into users' brain health. It is estimated that 55 million individuals worldwide suffer from some form of dementia. Alzheimer's disease and related dementias being the leading causes, with numbers expected to triple by 2050.

Using computer science to save the bees

Matter and energy from Science Daily Feed - Tue, 03/04/2025 - 11:34am
Researchers have created a system to help beekeepers monitor and analyze the health of their beehives and take corrective actions to prevent colony collapse -- when a majority of the worker bees abandon the colony and its queen. Beehives use thermoregulation to ensure the hive temperature stays between 33 and 36 degrees Celsius, about 91 to 97 degrees Fahrenheit. For example, bees might cluster to create insulation when it's cold or fan their wings when it's hot. But when beehives experience external stressors, such as pesticides or unexpected weather events, they lose the ability to regulate the hive temperature.

This week’s Bill Maher clip

Why Evolution is True Feed - Tue, 03/04/2025 - 8:45am

In this latest nine-minute comedy/news bit from Bill Maher’s “Real Time,” a show that included Rahm Emanuel and Fareed Zakaria, Maher suggests who the Dems should run for President and Vice-President in 2028.

Ths clip, called “New Rule: The next Democratic Star” proffers a solution to the waning popularity of the Democratic Party and the increasing desire of its members to move to the center. Maher suggests John Fetterman as a potential Prez, because he comes off as someone who understands the average American.  He also notes that Fetterman shares some of the features that helped Trump win, the most important being “authenticity, balls, and charisma.”

Yes, Fetterman had a stroke and suffers from depression, but Trump is unhealthy and suffers from narcissism. Fetterman, however, has sensible and potentially winnable political views; as Maher says, “Fetterman says the four words that strike fear into the heart of every Republican who wants to hang onto power: ‘I am not woke’.”

Maher also suggests Mayor Pete as a possible VP candidate, and I’m for that, too. (He notes that a disabled President combined with a gay VP surely checks as many intersectionality boxes as one person of color.) If not Mayor Pete, than Gretchen Whitmer.

This is a very good one; watch it!
