Stone tools and mastodon bones occur in an undisturbed geological context at the Page-Ladson site, Florida. Seventy-one radiocarbon ages show that ~14,550 calendar years ago (cal yr B.P.), people butchered or scavenged a mastodon next to a pond in a bedrock sinkhole within the Aucilla River. This occupation surface was buried by ~4 m of sediment during the late Pleistocene marine transgression, which also left the site submerged. Sporormiella and other proxy evidence from the sediments indicate that hunter-gatherers along the Gulf Coastal Plain coexisted with and utilized megafauna for ~2000 years before these animals became extinct at ~12,600 cal yr B.P. Page-Ladson expands our understanding of the earliest colonizers of the Americas and human-megafauna interaction before extinction.

I am not a paleontologist, and am not educated in the timeline indicated in this paper. Is this the first time such evidence has been found?

“It’s a very solid paper experimentally,” says evolutionary genomicist B. Franz Lang of the University of Montreal in Canada. “If you’d like me to bet, I’d give them 90% probability that they are correct.” To strengthen the case, he says, researchers need to perform a detailed microscopic analysis to confirm the absence of the organelles. Evolutionary biochemist Mark van der Giezen of the University of Exeter in the United Kingdom also wants to see further evidence that Monocercomonoides doesn’t harbor rudimentary mitochondria. Nonetheless, he says, the study expands our view of eukaryotes’ capabilities. “It shows that eukaryotic life is more flexible than what the textbooks say.”

New tabletop detector “sees” single electrons

MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.

As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the electrons, which can be used to map the electrons’ precise activity over several milliseconds.

Smartphone, Finger Prick, 15 Minutes, Diagnosis—Done!

We need more of this.

 "A team of researchers, led by Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has developed a low-cost smartphone accessory that can perform a point-of-care test that simultaneously detects three infectious disease markers from a finger prick of blood in just 15 minutes. The device replicates, for the first time, all mechanical, optical, and electronic functions of a lab-based blood test. Specifically, it performs an enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy: all necessary power is drawn from the smartphone. It performs a triplexed immunoassay not currently available in a single test format: HIV antibody, treponemal-specific antibody for syphilis, and non-treponemal antibody for active syphilis infection."

....

 Sia estimates the dongle will have a manufacturing cost of $34, much lower than the $18,450 that typical ELISA equipment runs.

There's my Chippy

A set of three observations with the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. They show that the lander survived its Dec. 25, 2003, touchdown enough to at least partially deploy its solar arrays.
The Beagle 2 Mars Lander, built by the United Kingdom, has been thought lost on Mars since 2003, but has now been found in images from NASA's Mars Reconnaissance Orbiter.

One of our greatest neuroscientists died on January 11.
Dr. Mountcastle was first person to describe how the cells in the higher regions of the brain are organized.

+Angelina Lenahan I imagine I would have been speechless as well. A few of my favorite childhood memories involve my family being glued to the TV set watching his underwater world unveiled. He was one of the most influential scientists of my youth.

I hope you didn't serve seafood.

What was your impression of him after dinner?

Until Google's business model shifts from predicting human love for pizza and porn (something a five neuron network can distinguish), there is zero incentive to predict anything that requires any actual real time computation. The "genius" of Google's original solution was that some fairly complex looking language and behavior parsing could be reduced to an index without a whole lot of computation, and requiring almost no computing with each subsequent search request. All this much-hyped deep learning requires some serious computation and is therefore not in anyway applicable within a model that skims nano fractions of pennies off each consumer transaction (google's revenue model). Google is in the "survey says" business. It's public relations challenge is to make a bottom feeder business seem complex and inspired. All this talk of AI and deep learning and quantum computing and singularity tech rapture is exactly like a garbage pickup empire talking about building trash powered galactic space ships (oops, my facetious example is exactly what Google disciples actually believe).

What spider is this?

It was caught indoors near Houston, Texas, USA.

NASA launch of the Magnetospheric Multiscale (MMS) mission is only a few minutes away. Catch it live, or not.

Oh wow! .. As if you could reach out and touch it! Comet 67P from just 8 km from the surface.

Supreme Court Blocks Texas’ Harsh Abortion Restrictions, Keeping Clinics Open

On Tuesday evening, the Supreme Court issued an injunction that will allow abortion clinics in Texas to remain open, temporarily blocking a package of harsh abortion restrictions that Texas lawmakers approved last summer. That measure, which was unsuccessfully filibustered by gubernatorial candidate Wendy Davis, requires that abortion clinics make costly renovations to bring their building codes in line with ambulatory surgical centers and stipulates that abortion doctors must secure admitting privileges from local hospitals. More via the link.

Dear Dr. Driscoll,
I thank you for your good message to me. I´ve been very much pleased with your acceptance of me. I hope that our interest in blogging activities will be reciprocal. Well, let me know if you visit to my blog someday. I think some of your tinkering has been close to me too.
I´ve been very interested in biology including the best of all the mysteries The Mother of The Nature has ever created, i.e. the human brain.
With best wishes
