Instead, Cooper argued that mobile networks should be using access point base stations, or femtocells: broadband-connected local cell stations that beam cell signals over focused areas inside of buildings.
It's no coincidence that Cooper sees smart antennas as the savior of the wireless industry: He serves as chairman of ArrayComm, a company that develops software for using antenna arrays to calculate the origin of cell signals.
One phone-sized device can block cell phone signals in a 20 foot radius.
Searchers used the trajectory of the helicopter and cell phone signals from Ruppert's phone to narrow down the rescue area.
Authorities and rescuers used the trajectory of the helicopter and cell phone signals from Ruppert's phone to narrow down the search area.
These drugs--such as Herceptin for breast cancer (Genentech) and Erbitux for colon cancer (Eli Lilly)--were designed to bind to signaling molecules on tumors and disrupt cell growth signals.
Novartis is in final trials of a drug that may help the one-third of acute myeloid leukemia cases with a gene mutation that turns on cell-growth signals.
This data springs from such diverse sources as weather, social media posts, digital pictures and videos, purchase transaction records and cell phone GPS signals, to name a few.
Certainly, something unusual is happening in the process by which the egg cell sends out signals to reprogram its new nucleus and put the developmental genes back into action.
As for revving up revenue, the company planned to wire its fleet with technology that would allow passengers to receive cell-phone signals and connect wirelessly to the Internet--without interfering with electronic transmissions to and from the cockpit.
The fact that a dying cancer cell sends out suicide signals to other cells has been dubbed the bystander effect.
Dr Lefkowitz started investigating the receptors by following the movement of radioactive isotopes attached to hormones within cells in the laboratory, trying to track down how signals get through cell membranes.

Once you house an antenna structure inside of an aluminum body, you also have shadowing effects to overcome, this is caused by the metal body affecting the radiated signal, as well as the inbound signals from the cell sites.
The fix, he argued, is to better understand the location of a cellphone user--a solution that will also reduce inefficiency of cell towers that broadcast radio signals and "listen" to cellphone radios in all directions rather than dialing in their "attention" on the user.
For a T cell to become active, it must receive signals from another part of the immune system called an antigen-presenting cell.
That serves to amplify the transmission of signals from one nerve cell to another.
Erbitux and Vectibix are antibodies that bind to receptors on the cell surface called EGF and blocks signals that turn kras on.
It is also backed up by work done on both people and laboratory animals, which shows that stress changes the activity of neurotransmitters, the chemicals that carry signals from one nerve cell to another in the brain.
Paul Krzyzanowski of the Canadian Stem Cell Network covered that meeting for the Signals blog.
These changes alter a cell's ability to conduct electrical signals, and thus to transmit messages along their lengths.
Scientists were able to detect signals from heart and nerve cell electro-flesh made this way, allowing them to measure changes in response to certain drugs.

These proteins transmit chemical signals into a wide variety of cell types.
At the time, the hot research area was in testing G-protein-coupled receptors, or GPCRS. These proteins transmit chemical signals into a wide variety of cell types.
The Novartis drug suppresses a protein called MTOR (mammalian target of rapamycin), which receives incoming growth signals from the surface of the cell and directs them to grow fatter, a necessary step before cell division.
The reason the Swiss Army knife approach could prove more effective is that many of the growth-promoting proteins involved in cancer are kinases, proteins that relay signals from one part of the cell to another.
Fibrogen's other approach, a joint effort with Japan's Sankyo , is to screen thousands of small-moleculeproteins on their shelves and those of other firms to see whether one or two will block CTGF from binding with receptors or knock out one of the collagen-producing signals that CTGF sends into a cell nucleus.
For many years, passengers have been told that some electronic devices, including cell phones, can interfere with aircraft navigation and communication signals.
When EGF docks on a receptor, it signals to an enzyme called tyrosine kinase to regulate cell growth.
At higher frequencies, the signals are best used when combined with closely spaced cell sites that can serve streaming video and data very efficiently.
Cell phones, for instance, the major target of wiretapping, have their wireless signals encrypted by default.
