Current climate model simulations are overestimating future sea-level rise

The melting rate of the Antarctic ice sheet is mainly controlled by the increase of ocean temperatures surrounding Antarctica. Using a new, higher-resolution climate model simulation, scientists from Utrecht University found a much slower ocean temperature increase compared to current simulations with a coarser resolution. Consequently, the projected sea-level rise in 100 years is about 25% lower than expected from the current simulations. These results are published today in the journal Science Advances.

Estimates for future sea-level rise are based on a large ensemble of climate model simulations. The output from these simulations helps to understand future climate change and its effects on the sea level. Climate researchers continually aim to improve these models, for example by using a much higher spatial resolution that takes more details into account. "High-resolution simulations can determine the ocean circulation much more accurately," says Prof. Henk Dijkstra. Together with his Ph.D. candidate René van Westen, he has been studying ocean currents in high-resolution climate model simulations over the past few years.

The chances of powerful geomagnetic storms may have just doubled

If you think you are safe from geomagnetic storms, think again. A new study just published in the journal Space Weather finds that powerful storms may be twice as likely as previously thought.

Jeffrey Love of the US Geological Survey, who authored the study, analyzed Earth's strongest geomagnetic storms since the early 1900s. Previous studies looked back only to the 1950s. The extra data led to a surprise:

"A storm as intense as, say, the Québec Blackout of 1989 is predicted to occur, on average, about every four solar cycles. This is twice as often as estimated using only the traditional shorter dataset," says Love.

Comment: The Great Québec Blackout was caused by double tap CMEs

The Cambrian Explosion has just gone nuclear

Here are two very interesting updates to my recent articles at Evolution News on alleged Ediacaran animals and the Cambrian Explosion.

Dickinsonia Could Still Be a Fungus

In my article (Bechly 2018b) about the iconic and enigmatic Ediacaran organism Dickinsonia, I showed why in spite of new biomarker evidence presented by Bobrovskiy et al. (2018), Dickinsonia is unlikely to be an animal. Such evidence-based skepticism is of course not greatly appreciated in Darwinist circles and provoked a response.

At the Peaceful Science forum, an anonymous atheist and self-professed blogging graduate student (evograd 2018), who obviously lacks sufficient expertise as well as some reading comprehension, criticized my article with a red herring quibble about two of six references that Bobrovskiy et al. quoted (which I actually never disputed), while ignoring all real arguments. Just read my article and compare it with his criticism to decide for yourself if it has any merit. Anyway, this young know-it-all then triumphantly proclaimed:

Watch a monkey equipped with Elon Musk's Neuralink device play Pong with its brain

Elon Musk's Neuralink, one of his many companies and the only one currently focused on mind control (that we're aware of), has released a new blog post and video detailing some of its recent updates — including using its hardware to make it possible for a monkey to play Pong with only its brain.

In the video above, Neuralink demonstrates how it used its sensor hardware and brain implant to record a baseline of activity from this macaque (named "Pager") as it played a game on-screen where it had to move a token to different squares using a joystick with its hand. Using that baseline data, Neuralink was able to use machine learning to anticipate where Pager was going to be moving the physical controller, and was eventually able to predict it accurately before the move was actually made. Researchers then removed the paddle entirely, and eventually did the same thing with Pong, ultimately ending up at a place where Pager no longer was even moving its hand on the air on the nonexistent paddle, and was instead controlling the in-game action entirely with its mind via the Link hardware and embedded neural threads.

Powerful algorithms used by Netflix, Amazon and Facebook can 'predict' the biological language of cancer and neurodegenerative diseases like Alzheimer's, scientists have found.

Big data produced during decades of research was fed into a computer language model to see if artificial intelligence can make more advanced discoveries than humans.

Academics based at St John's College, University of Cambridge, found the machine-learning technology could decipher the 'biological language' of cancer, Alzheimer's, and other neurodegenerative diseases.

Study finds over 5,000 tons of extraterrestrial dust fall to Earth each year

Electron micrograph Concordia micrometeorite

Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites.

An international program conducted for nearly 20 years by scientists from the CNRS, the Université Paris-Saclay and the National museum of natural history with the support of the French polar institute, has determined that 5,200 tons per year of these micrometeorites reach the ground. The study will be available in the journal Earth & Planetary Science Letters from April 15.

Micrometeorites have always fallen on our planet. These interplanetary dust particles from comets or asteroids are particles of a few tenths to hundredths of a millimeter that have passed through the atmosphere and reached the Earth's surface.

First results from Fermilab's Muon g-2 experiment strengthen evidence of new physics

The Muon g-2 ring sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the precession (or wobble) of muons as they travel through the magnetic field.

Combined results from Fermilab and Brookhaven show strong evidence that our best theoretical model of the subatomic world is incomplete.

The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists' best theory, the Standard Model of particle physics. This landmark result, made with unprecedented precision, confirms a discrepancy that has been gnawing at researchers for decades.

The strong evidence that muons deviate from the Standard Model calculation might hint at exciting new physics. Muons act as a window into the subatomic world and could be interacting with yet undiscovered particles or forces.

CBET 4953 & MPEC 2021-G80, issued on 2021, April 07, announce that an apparently asteroidal object (magnitude ~21.0) discovered on CCD images obtained with the F51 Pan-STARRS 1 survey's 1.8m Ritchey-Chretien on 2019, October 22.22 and designated A/2019 U5 (cf. MPEC 2019-V10) has been found to show cometary appearance by other CCD observers over the past half year. The new comet has been designated C/2019 U5 (PANSTARRS).

Stacking of 20 unfiltered exposures, 120 seconds each, obtained remotely on 2021, April 02.1 from Z08 (Telescope Live, Oria) through a 0.7 m f/8 Ritchey Chretien + CCD, shows that this object is a comet with a compact coma about 15" arcsec in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible Nova in Sgr (TOCP Designation: PNV J17581670-2914490) we performed some follow-up of this object through a TEL 0.6-m f/6.5 astrograph + CCD located in the El Sauce Observatory in Chile and operated by Telescope Live network (MPC Code X02).

This transient has been discovered by Andrew Pearce at 8.4 mag (unfiltered) on 2021-04-04.825 UT using a Canon 1100D DSLR camera with a 100mm f/2.8 lens. Total exposure time was 20 seconds (2 x 10s images stacked). Rob McNaught reported non-detection on 2021-04-02.776 UT (unfiltered limiting mag 11.0).

On images taken on April 06.40, 2021 we can confirm the presence of an optical counterpart with B-filtered CCD magnitude +8.955 (R-filtered & V-filtered images were saturated in 5-second exposures) at coordinates:

R.A. = 17 58 16.08, Decl.= -29 14 56.4

(equinox 2000.0; Gaia DR2 catalogue reference stars for the astrometry).

The Bacho Kiro cave in Bulgaria. The research is based on analysis of several ancient human remains – including a whole tooth and bone fragments – found in a cave in Bulgaria last year.

Genetic sequencing of human remains dating back 45,000 years has revealed a previously unknown migration into Europe and showed intermixing with Neanderthals in that period was more common than previously thought.

The research is based on analysis of several ancient human remains - including a whole tooth and bone fragments - found in a cave in Bulgaria last year.

Genetic sequencing found the remains came from individuals who were more closely linked to present-day populations in east Asia and the Americas than populations in Europe.

Comment: Bacho Kiro has proved to be a treasure chest of prehistoric information:
