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.

That is just ridiculously cool, but is there a purpose/benefit to doing so?

Never mind - I should have read the abstract first. Thank you for sharing it.

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.

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
Zdenek Zacek

TWIS is still live if you really have that urge to listen to some live science discussions right, spanking now.
 
TWIS is on! Robot time!!! Are you with us? http://twis.org/live

Dear Cloud Monsters,

Please clear out of my view for just a few hours later tonight, so I can watch this with my wife, cats and dog.

Thank you in advance. - Earth Monster
 
The Perseid meteor shower that streaks across skies every August will peak tonight, around 3-4am (across all time zones). Don’t forget to look up!

+Ken MacMillan The clouds parted long enough for me to see 5 pretty good ones. I'll try again tonight. May the weather cooperate with you tonight.

For fellow bubble popping enthusiasts, here is another reason to love bubble wrap: 

Bubble wrap serves as sheet of tiny test tubes in resource-limited regions

From the release: Popping the blisters on the bubble wrap might be the most enjoyable thing about moving. But now, scientists propose a more productive way to reuse the popular packing material — as a sheet of small, test tube-like containers for medical and environmental samples. Their report, which shows that analyses can take place right in the bubbles, appears in the ACS journal Analytical Chemistry.

Here is a link to the research abstract: http://pubs.acs.org/doi/abs/10.1021/ac501206m

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

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?

Join us for a +Science on Google+  Hangout on Air as we speak to Professor +Vincent Racaniello and Dr +Tara C. Smith about the recent Ebola outbreak. We will discuss the basics of Ebola, why the epidemic has spread, how it might be curtailed, and debunk some of the myths surrounding this outbreak. Please leave your questions on the Event page.

Vincent is a professor of virology at the University of Columbia and is a fantastic science communicator. Tara is an epidemiologist at Kent State University who has written numerous articles debunking some of the myths surrounding Ebola. This HOA will be hosted by Dr +Buddhini Samarasinghe  and Dr +Zuleyka Zevallos. You can tune in on Sunday August 10th at 2.30 PM Pacific, 5.30 PM Eastern. The hangout will be available for viewing on our YouTube channel (https://www.youtube.com/ScienceHangouts) after the event.
This Hangout On Air is hosted by Science on Google+. The live video broadcast will begin soon.
