Charles Darwin’s notebooks, worth millions, stolen from Cambridge University Library

Survival of the fittest apparently extends to notebooks.

The notebooks of Charles Darwin and were reported stolen from the Cambridge University Library, The Associated Press reported Tuesday.

Even Interpol has been notified of the alleged theft, which is being investigated by police.

Included in the pair of notebooks, which are estimated to be worth millions, is the “Tree of Life” sketch by the scientist, who died in 1882.

Though the prized possessions haven’t been seen for two decades, library staff trusted the notebooks must be lost somewhere in the archives of the repository, which boasts more than 130 miles of shelving and nearly 10 million books, manuscripts, and more. After an in-depth search through 189 boxes in the Darwin Archive proved fruitless, they concluded the manuscripts must have been nabbed.

University librarian Jessica Gardner, who also serves as director of library services, noted the theory that the notebooks had been “mis-shelved or misfiled” is now “not a sufficient position or set of actions to take.”

In 1866, fellow British naturalist Alfred Russel Wallace, suggested that Darwin replace his “natural selection” theory with that of “survival of the fittest,” a term coined by Herbert Spencer two years prior after he read Darwin’s “On the Origin of Species.”

Psyche, an asteroid believed to be worth $10,000 quadrillion, is observed through Hubble Telescope in new study

A rare metallic asteroid about three times farther away from the sun than our planet could yield secrets about Earth’s molten core, and scientists want to learn all about it.

A new study published Monday in The Planetary Science Journal takes a closer look at this mysterious asteroid, using data from the Hubble Telescope.

Located between Mars and Jupiter, Asteroid 16 Psyche is one of the most massive objects in the asteroid belt in our solar system, and with a diameter of about 140 miles, it is roughly the same length as Massachusetts (if you exclude Cape Cod).

The exact composition of Psyche is still unclear, but scientists think it’s possible the asteroid is mostly made of iron and nickel. It’s been hypothesized that a piece of iron of its size could be worth about $10,000 quadrillion, more than the entire economy on our planet.

Scientists believe that Psyche could be the metallic core of an early planet that lost its mantle and crust due to collisions that might have occurred early in the formation of the solar system.

In 2022, NASA will send an unmanned spacecraft to Psyche to study it up close and better determine its composition.

In the meantime, the new study in The Planetary Science Journal looked at Psyche through the Hubble Telescope at two specific points in its rotation, to capture both sides of the asteroid.

The study includes the first ultraviolet observations of Psyche, furthering our understanding of its surface and its possible composition.

“We looked at the way that the ultraviolet light reflected off of the asteroid surface,” Tracy Becker told CNN. She is the lead author of the study and a planetary scientist at the Southwest Research Institute.

“The way the ultraviolet light was reflected from Psyche was very, very similar to the way iron reflects sunlight,” she explained.

The importance of studying Psyche

Studying Psyche could help us better understand those early times in the history of our solar system, when objects would have had “higher inclinations and crazier eccentricities,” and would have had more opportunities to collide with each other, Becker told CNN.

If Psyche is the metal core of a planet that never was, studying it more closely could tell us a lot about the core of our planet, which we wouldn’t be able to explore, Becker said.

The study also detected two possible signals of changes to the surface of Psyche due to solar winds, according to Becker.

“The first one was that as we went deeper into the UV, we started to see the asteroid get brighter, which is pretty rare,” Becker said.

“In the past, when we’ve seen that on certain planetary bodies, including the moon, that often tells us that it’s due to the charge particles from the sun interacting with the materials on the surface, causing this brightening. We call that space weathering,” she added.

The second signal, according to Becker, was the detection of iron oxide ultraviolet absorption

The Orionid meteor is fading but still worth checking out. Here’s how

lspn-comet-halley

Halley’s Comet in 1986.


NASA

Look up skywatchers. The Orionid meteor shower officially peaked last Tuesday night and Wednesday morning, but it should still be worth getting up early for this week. The American Meteor Society forecasts that a handful of meteors or more per hour should be visible.

The Orionids are considered a major meteor shower based on the amount of visible meteors that can be seen racing toward inevitable doom during its active period, which runs roughly from the first week of October to the first week of November.  

The Orionids are really just bits of dust and debris left behind from famed Comet Halley on its previous trips through the inner solar system. As our planet drifts through the cloud of comet detritus each year around this time, all that cosmic gravel and grime slams into our upper atmosphere and burns up in a display we see on the ground as shooting stars and even the occasional fireball.

The Orionids can epitomize the old phrase “blink and you might miss it” as they enter our atmosphere at an extremely fast velocity of roughly 147,000 miles per hour (66 kilometers per second). That said, a fair amount of these meteors leave persistent trails that last for a few seconds. Some even fragment and break up in a more spectacular fashion. 

To catch the show, the advice is the same as for all celestial spectator events: Find a spot away from light pollution with a wide open view of the night sky. Bundle up if needed, lay back, relax and let your eyes adjust. You don’t need to focus on any part of the sky, but the Orionids are so named because their trails appear to originate from the same general area of the sky as the constellation Orion and the bright star Betelgeuse

The absolute best time to look for the Orionids in 2020 was probably in the early morning hours before dawn on Oct. 21, but this shower is known for an extended peak, so you should have a good chance of seeing some meteors if you get up early this week.

The moon will set before peak morning viewing hours, so that’ s another perk this year. Enjoy the show and as always, please share any great meteor shots you might capture with me on Twitter @EricCMack

The humic acid segment is projected to be the largest segment in the humic-based biostimulants market during the forecast period.

Humic acid is usually applied to make nutrients and micronutrients readily available to the plants and increase the plant’s resistance to stress. Due to its immense and cheap availability in countries like China and India, the demand for humic acids for plant growth is boosting. It can be combined with fertilizers for better results, which is practices in most countries.

The liquid segment is estimated to account for the largest market share, in terms of value, in 2020.

The liquid formulation is easy in handling and application; hence most of the farmers use liquid formulation.  The application of liquid humic-based biostimulants enhances efficiency by distributing evenly on the required area. Therefore, manufacturers are also offering most biostimulant products in the liquid formulation as per the requirement.

The seed treatment segment is projected to witness the fastest growth in the humic-based biostimulants market, 2020 to 2025.

Seed treatment is the method that is mostly used by every farmer where the seeds are applied with pesticides to develop resistance in plants. Similarly, humic-based biostimulants can also be applied to the seeds before sowing, which will improve the uptake of nutrients and water retention capacity.  It is not a very popular method presently, but in the coming years, it will gain more popularity because of the benefits associated with it.
