Haupt, who works as an astronomy instrumentation engineer at Brookhaven National Laboratory in New York, detailed how she took the rotary mechanism from an old Trimline telephone, paired it with a microcontroller and an Adafruit Fona 3G cell transceiver, put it all into a 3D-printed casing, and built something that could replace her daily flip phone.
Stingrays derive their power by pretending to be cell towers, tricking nearby devices into connecting to them instead of the real thing.Without confirming that a cell tower is genuine, devices could wind up connecting to any rogue base station that's set up to broadcast system information messages.
Soon after the procedure, she came to a local hospital with low blood pressure and what turned out to be a dangerous antibiotic-resistant infection from a bacteria called Enterococcus faecalis.
De’Broski Herbert, an immunology researcher at the University of Pennsylvania, was the first to notice the emergence of tuft cells, which are rich in “taste” receptors, developing in the infected lungs of sick mice.
But if you want to replace a faulty gene with a healthy one, things get more complicated .In addition to programming a piece of guide RNA to tell Crispr where to cut, you have to provide a copy of the new DNA and then hope the cell’s repair machinery installs it correctly.
It’s unfair,” says Ian Philabaum, a program director at Immigration Law Lab. Of the nearly 1 million asylum cases waiting to be heard, about 74 percent are for people coming from El Salvador, Guatemala, Honduras, and Mexico.
The researchers found that they could use their first stingray attack to modify a device's stated category number during the connection process, downgrading it to an older network.
This process is known as exciton fission and means that the solar cell is able to use high energy photons from the blue-green part of the visible spectrum. Baldo says that using tetracene could bump the theoretical energy efficiency limit up to 35 percent—higher than was ever thought possible for single-junction cells.
Cellebrite, too, has likely possessed the ability to unlock iOS 12.3 devices prior to this announcement, says Dan Guido, the founder of the New York-based security firm Trail of Bits and a longtime iOS-focused security researcher.
Depth of Field: The Power of Sandra Bland's Cell Phone Video. An image from the 39-second video Sandra Bland recorded with her cell phone in 2015.
The CIA Has Some of Its Own. From the agents of the Mission: Impossible franchise to Arya Stark on Game of Thrones , characters in movies and TV shows have been able to pull off some serious stunts while wearing the faces of others.
On Monday, US secretary of state Mike Pompeo scolded China for using civilian polar research to further its military and commercial goals, including opening up a new “Polar Silk Road” for trade and shipping. Yun says Chinese scientists don’t see the conflict between scientific research and national goals of resource development.
Last week, I went to the cell phone store across the street from my apartment in Brooklyn to purchase a SIM card for Baby, after one from AT&T failed to work with the device.
Lucas Pope's Return of the Obra Dinn won big at this week's Independent Games Festival. Since nearly everyone involved in the videogame industry spent the week at the Game Developers Conference discussing the future and reflecting on the past, a lot of news came out of that annual gathering.
In his book Life at the Speed of Light , Craig Venter himself—the brash, iconoclastic scientist and entrepreneur, and the institute’s founder—described his project as the first “synthetic cell”; it was named Mycoplasma mycoides JCVI-syn1.0, but it acquired the nickname “Synthia.” You can tell a lot about a biotech application about the way it’s named (“noninvasive,” “de-extinction”), and Venter’s new cell is no different: its formal name highlights the merging of the biological and digital.
Seven years ago, the bug that causes strep throat, toxic shock syndrome, and flesh-eating disease supplied researchers with their first gene-snipping nuclease, Cas9.
Odnoviun documented the spy holes in those doors at eight former prisons in Lithuania, Estonia, Latvia, Poland, Ukraine, and Germany for his series Surveillance . "I considered people on both sides of the spy hole to be prisoners of the system in their own ways," Odnoviun says.
Using a new method for measuring unplanned edits, a team of American, Chinese, and European scientists has found that the same base editor, widely in use by researchers today, actually messes up the genome at an eyebrow-raising rate. Besides the base editors, Steinmetz’s group also tested good ‘ol Crispr 1.0, the gene-editing workhorse of the biological research world.
Common Networks revealed Monday that its millimeter wave service in Alameda relies on Terragraph, a hardware design Facebook open sourced as part of its Telecom Infrastructure Project.
(It affects about 1 percent of human men and a far smaller fraction of women; the more common form of red-green colorblindness, a mutation called "deuteranopia" in the cone that senses greenish, medium-wavelength light is a little more common—like 6 percent of men.) The implication of all those likewise-envisioned brothers was that Daltonism somehow ran in families—though Darwin’s Origin of Species and the concept of evolution were still six decades in the future.
The calls have not stopped since.Allison’s breakthrough was the discovery of a sort of secret handshake that cancer uses to evade the immune system, and a means to block that handshake—what the Nobel committee hailed as “a landmark in our fight against cancer,” which has “revolutionized cancer treatment, fundamentally changing the way we view how cancer can be managed.” (Allison’s co-recipient was Tasuku Honjo of Kyoto University.) Advances in cancer typically come in 50-year increments; the science that Allison and Honjo helped advance, cancer immunotherapy, has made a generational leap seemingly overnight.Adapted from The Breakthrough: Immunotherapy and the Race to Cure Cancer by Charles Graeber.
Instead, the cells of the damaged tissue turn the clock back all the way to a more fetal state, tapping into the proliferative power that once characterized development — and a program thought to have long gone silent.Atom Bombs and Self-Renewing CellsIn the early 1900s, scientists theorized that the specific blood cell types they’d learned to distinguish from one another under a microscope — red blood cells, white blood cells and platelets — came from a common, more primitive source: a stem cell.
In a previous blog, I used the metaphor of marriage to explore the dynamic of public-private partnerships (PPPs) as relationships created between two parties with often very different expectations and methods of communication.
Sequencing technologies, for one, can reveal how cells with the same exact DNA turn their genes on or off in unique ways—and these methods are beginning to reveal that the brain is a more diverse forest of bristling nodes and branching energies than even Ramón y Cajal could have imagined.On Monday, an international team of researchers introduced the world to a new kind of neuron, which, at this point, is believed to exist only in the human brain.
