NASA Unveils the 'Global Selfie' We Made on Earth Day

Posted on by

By Alan Boyle

NASA has taken the wraps off a 3.2-gigapixel "Global Selfie" that was built from 36,422 images shared on social media one month ago, for Earth Day.

The space agency says more than 50,000 pictures from 113 countries and regions around the world were posted on or around April 22, using the #globalselfie hashtag on Twitter, Instagram, Facebook, Google+ and Flickr. Those pictures were curated and processed to blend into two hemispheres' worth of Earth Day imagery from the Visible Infrared Imaging Radiometer Suite on the Suomi NPP satellite.

A full-resolution version of the Global Selfie is hosted on the Web by GigaPan, and if you zoom in far enough, you can look into the smiling faces of all the folks who contributed to the planetary picture. Want to see another world-spanning selfie? Check out last year's "Wave at Saturn" mosaic.

Zoom in far enough and you can see the individual Earth Day selfies that were combined to produce NASA's monster "Global Selfie."

Engineers look to scale up nanomanufacturing

Posted on by

Engineers have been developing nanotechnology that could put tiny sensors in just about any material imaginable. Some of these sensors could be woven into clothing to save soldiers from chemical weapons, monitor vital signs from a Band-Aid, or make solar panels more efficient.

Making such small devices is labor intensive, so they are expensive to produce. Mass manufacturing flat, flexible sensors would reduce the cost, says University of Massachusetts Amherst chemical engineer Jim Watkins. He and his team at the NSF Center for Hierarchical Manufacturing are working on a roll-to-roll process to manufacture printable coatings.

You can have something that both performs better and is less expensive. Thats really the heart of nanomanufacturing, Watkins said.

Science correspondent Miles OBrien explains how these future assembly lines work in the National Science Foundations series Science Nation.*

Drexel University College of Medicine Study Finds Novel Molecular Mechanism for Breast Cancer Cell Metabolism and …

Posted on by

Philadelphia, PA (PRWEB) May 22, 2014

A study from the Department of Biochemistry and Molecular Biology at Drexel University College of Medicine offers a potential new therapy for difficult-to-treat breast cancers. A team of investigators discovered that targeting a specific enzyme can kill triple-negative breast cancer cells, but spare non-tumor cells as well. The study is currently available in the online edition of Molecular Cell.

Breast cancer is the worlds leading cancer in women, and the triple-negative breast cancer subtype is the deadliest and most difficult to treat since there is no targeted therapy currently available, said the studys lead investigator Mauricio J. Reginato, PhD, associate professor in the Department of Biochemistry and Molecular Biology. We hope this novel discovery may aid in developing new treatment protocols.

The team discovered that O-GlcNAc transferase (OGT), an enzyme that adds sugars to a number of nuclear and cytosolic proteins, is essential for allowing cancer cells to switch to glycolysis for energy demands. OGT regulates degradation of the hypoxia-inducible factor 1 (HIF-1a), a critical driver of cancer cell metabolism. Importantly, the study shows that reducing levels of OGT or blocking OGT activity with a small molecule selectively induced metabolic stress and cell killing in cancer cells but not in non-cancer breast cells. By profiling hundreds of metabolites, the team discovered that blocking OGT in tumor cells reduces critical metabolites involved in energy production that feeds cancer growth and survival. The authors also discovered that one metabolite elevated under these conditions alpha-ketoglutarate, a critical cofactor for HIF-1a regulation and degradation, is one mechanism by which OGT regulates HIF-1a.

The team showed that this tumor subtype contains higher expression of OGT and HIF-1a compared to other breast cancer subtypes. These results provide evidence that targeting OGT in difficult-to-treat triple-negative breast cancer may provide a future therapeutic option.

The members of the research team included: lead author Christina Ferrer and Valeria Sodi, both PhD candidates in the Molecular and Cell Biology and Genetics program; medical student John Falcone; and former student Thomas Lynch, PhD. This research is supported by National Cancer Institute R01 and F31 grants, and past CURE grants. This work also included collaborators from the University of Tennessee and Simon Fraser University in Canada.

Memphis Zoo visitors can park on grass over holiday weekend

Posted on by

MEMPHIS, TN -

(WMC) - Memphis Zoo visitors will be allowed to park on the grass over one of its busiest weekends of the year.

Representatives from the zoo, Overton Park Conservancy, and City of Memphis met at city hall to discuss the situation Friday morning.

After 23 years, the city has decided to end an unwritten agreement with the zoo that allowed it to park overflow cars on the 16-acre Overton park greensward when its 960 surface spots filled up.

Starting this weekend, Overton Park is starting shuttles that will run the crowd from the Overton Square parking garage to the zoo.

However, all parties agreed to allow parking on the greensward over Memorial Day weekend and then meet again next week to discuss more permanent solutions.

"We're pleased that we've had some movement toward a solution," Memphis Zoo President Chuck Brady said. "We're very concerned that our guests get to and from the zoo in a safe and pleasant environment."

"It [Friday morning's meeting] was productive," said Memphis Chief Administrative Officer George Little. "It was productive. It was helpful. Certainly, we've got a number of passionate stakeholders, but that's part of what makes Memphis great."

Little says the city is promoting the free shuttle service from the Overton Square garage into the park, but with it being the biggest weekend of the year, it was not the right time to close the greensward to cars.

"We felt there was too much risk for our guests of having a bad experience coming to our city," said Little. "We're very definitely open for business at the zoo. We want our guests to come. Hopefully there won't be any extra excitement that we have to charge them for."

App helps you find lookalike for Fido

Posted on by

By Doug Gross, CNN

The PetMatch app uses patented image-recognition technology to find you a pet that looks like one in a photo you share.

STORY HIGHLIGHTS

(CNN) -- Are you missing a beloved four-legged friend from the past? Or, on a far sillier note, would you like your very own Grumpy Cat or Doge?

A new app aims to help you find a lookalike for your departed or dream pet by using photo-matching software to find the closest match in your area.

PetMatch lets you upload a picture of a dog or cat, or use one from its gallery. It then tries to find you a pet available for adoption that is the closest possible match to the one you posted.

The app is from startup Superfish and uses its patented image-recognition technology. It scans your photo, registering details like the shape of an animal's mouth, the distance between its eyes, its coloring and its general size and shape.

This PetMatch search produced similar-looking cats to the one in the upper left.

Users can share their own photos or ones from the Web, like this shot of Grumpy Cat.

It then performs a similar search on PetFinder, a database with photos of hundreds of thousands of animals up for adoption throughout the United States, and gives you the closest overall matches, as well as the closest ones in your area.
