(Phys.org) —Radar systems today depend increasingly on phased-array antennas, an advanced design in which extensive grids of solid state components direct signal beams electronically. Phased array technology is replacing traditional electro-mechanical radar antennas – the familiar rotating dish that goes back many decades – because stationary solid state electronics are faster, more precise and more reliable than moving mechanical parts. http://phys.org/news283941719.html Technology Sun, 31 Mar 2013 09:42:35 EST news283941719 (AP)—The federal judge presiding over challenges to Google Inc.'s plans to create the world's largest digital library has refused to delay the 7-year-old case while Google appeals his decision to grant authors class certification. http://phys.org/news265484124.html Technology Wed, 29 Aug 2012 18:50:03 EST news265484124 (AP) -- There's another delay in efforts to create hundreds of Internet address suffixes to join ".com" and others in use. http://phys.org/news253888234.html Technology Tue, 17 Apr 2012 13:30:40 EST news253888234 In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do. http://phys.org/news232284828.html Biology Thu, 11 Aug 2011 12:35:09 EST news232284828 In his classes, Rifat Sipahi often challenges his engineering students to explore a problem that is literally out of this world. For example, he notes that operators in Houston control NASA’s Mars Exploration Rover, but it takes several minutes to transmit steering instructions from Earth to the vehicle — which presents challenges for scientists, who must wait to see the rover actually move before sending its next command. http://phys.org/news216499488.html Technology Wed, 09 Feb 2011 18:45:15 EST news216499488 A new automated vocal analysis technology could fundamentally change the study of language development as well as the screening for autism spectrum disorders and language delay, reports a study in the July 19 online Proceedings of the National Academy of Sciences. http://phys.org/news198764780.html Medicine & Health Mon, 19 Jul 2010 15:00:13 EST news198764780 Children born to mothers prescribed the heroin substitute methadone during pregnancy may be at risk of wide-ranging sight problems, indicates a small study published ahead of print in the British Journal of Ophthalmology. http://phys.org/news191098477.html Medicine & Health Wed, 21 Apr 2010 19:54:54 EST news191098477 About 1 in 4,000 infants has a brain injury known as pre- or perinatal brain lesions, mainly as a result of stroke, with risk factors involving both mothers and babies. Children with early brain lesions that affect one side of the brain often take longer to reach early language milestones; these delays normalize for many but persist for some. New research has found that children's gesturing at 18 months can identify those children who will have these later language delays. http://phys.org/news188716224.html Medicine & Health Thu, 25 Mar 2010 08:10:01 EST news188716224 In a new study, infants averaging six months of age who exhibited positional plagiocephaly (flat head syndrome) had lower scores than typical infants in observational tests used to evaluate cognitive and motor development. Positional or deformational plagiocephaly may occur when external forces shape an infant's skull while it is still soft and malleable, such as extended time spent lying on a hard surface or in one position. http://phys.org/news185435471.html Medicine & Health Mon, 15 Feb 2010 06:10:02 EST news185435471 Many pediatricians score high on screening their patients for developmental delays, but barely make a passing grade in referring children with suspected delays for further testing or treatment, according to a study from Johns Hopkins Children's Center and other institutions to appear in the February issue of Pediatrics. http://phys.org/news183753239.html Medicine & Health Tue, 26 Jan 2010 18:34:33 EST news183753239 (PhysOrg.com) -- UQ researcher Dr Lane Strathearn sees strengthening the bond between mother and baby as a possible way of reducing childhood neglect. http://phys.org/news179595391.html Medicine & Health Wed, 09 Dec 2009 16:30:03 EST news179595391 The loss of a gene through deletion of genetic material on chromosome 15 is associated with significant abnormalities in learning and behavior, said a consortium of researchers led by Baylor College of Medicine in a report that appears online today in the journal Nature Genetics. http://phys.org/news176908780.html Medicine & Health Sun, 08 Nov 2009 13:21:46 EST news176908780 A phase I clinical trial enrolled its first patient only two days after U.S. Food and Drug Administration clearance of the experimental drug for a first-in-human cancer trial, a milestone that normally takes three to six months. Investigators from The University of Texas M. D. Anderson Cancer Center and pharmaceutical company AstraZeneca have reported their work in the Journal of Clinical Oncology published online on August 3rd. http://phys.org/news168538136.html Medicine & Health Mon, 03 Aug 2009 17:09:18 EST news168538136 Yale School of Medicine researchers have identified proteins associated with early onset neonatal sepsis (EONS), a stealthy bacterial infection linked to premature birth, illness and death. Using protein analysis, the researchers have found the biomarkers that can provide key information on how EONS develops. http://phys.org/news152470600.html Medicine & Health Thu, 29 Jan 2009 16:57:12 EST news152470600 Individuals with Medicaid insurance and those who live in neighborhoods with lower household incomes appear less likely than others to reach the hospital within two hours of having a heart attack, according to a report in the September 22 issue of Archives of Internal Medicine. http://phys.org/news141322932.html Medicine & Health Mon, 22 Sep 2008 17:22:12 EST news141322932 If you had a choice between receiving $1,000 right now or $4,000 ten years from now, which would you pick? Psychologists use the term "delay discounting" to describe our inability to resist the temptation of a smaller immediate reward in lieu of receiving a larger reward at a later date. Discounting future rewards too much is a form of impulsivity, and an important way in which we can neglect to exert self-control. http://phys.org/news140173735.html Medicine & Health Tue, 09 Sep 2008 10:08:55 EST news140173735 A new study from researchers at the University of Pittsburgh and Carnegie Mellon University sheds light on why smokers' intentions to quit "cold turkey" often fizzle out within days or even hours. http://phys.org/news138979386.html Medicine & Health Tue, 26 Aug 2008 14:23:06 EST news138979386 Good things may come to those who wait, but research has proven that humans and animals actually prefer an immediate rather than a delayed reward. Now, a study published by Cell Press in the July 10 issue of the journal Neuron reveals how a decision-making region of the brain encodes information associated with the magnitude and delay of rewards. http://phys.org/news134829035.html Medicine & Health Wed, 09 Jul 2008 13:30:35 EST news134829035
