(Phys.org) —Researchers using NASA's Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice. http://phys.org/news290274650.html Space & Earth Wed, 12 Jun 2013 16:51:06 EST news290274650 An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago—a time when dinosaurs were around and may have even peeked over the rim, says a study led by the University of Colorado Boulder. http://phys.org/news273420123.html Space & Earth Thu, 29 Nov 2012 14:02:48 EST news273420123 (Phys.org)—One tropical lizard's tolerance to cold is stiffer than scientists had suspected. http://phys.org/news273166802.html Biology Mon, 26 Nov 2012 15:40:15 EST news273166802 (PhysOrg.com) -- Europe is likely to be hit by more violent winter storms in the future. Now a new study into the effects of climate change has found out why. http://phys.org/news252655769.html Space & Earth Tue, 03 Apr 2012 07:11:04 EST news252655769 On 4 March 1997 the Mars Pathfinder lander fell through the thin Martian atmosphere. During its descent, instrumentation aboard the lander recorded the changing atmospheric temperature, pressure, and density. http://phys.org/news248448038.html Space & Earth Tue, 14 Feb 2012 14:20:01 EST news248448038 (PhysOrg.com) -- In order to better understand how ceramics are able to resist heat, the National Science Foundation has awarded grants totaling half a million dollars to three research groups to look into how the ancient Greeks made their pottery, a process which allowed for as many as 100,000 vases to survive from ancient antiquity to now - a period of some twenty five hundred years. The hope is that such research will reveal more about the nature of iron-spinel chemistry, which is what gives ceramics an ability to withstand heat while remaining chemically stable. Getting a better grip on how ceramics work is critical to future space flight technological efforts, as ceramics are used to help space vehicles withstand both extreme hot and cold temperatures. http://phys.org/news244893108.html Chemistry Wed, 04 Jan 2012 10:00:02 EST news244893108 Tiny temperature changes on the Atlantic and Pacific oceans provide an excellent way to forecast wildfires in South American rainforests, according to UC Irvine and other researchers funded by NASA. http://phys.org/news240154707.html Space & Earth Thu, 10 Nov 2011 14:00:11 EST news240154707 Imec realized a fT/fMAX 245GHz/450GHz SiGe:C heterojunction bipolar transistor (HBT) device, a key enabler for future high-volume millimeter-wave low-power circuits to be used in automotive radar applications. These HBT devices also pave the way to silicon-based millimeter wave circuits penetrating the so-called THz gap, enabling enhanced imaging systems for security, medical and scientific applications http://phys.org/news237548370.html Technology Tue, 11 Oct 2011 10:39:44 EST news237548370 A five-year project led by the Georgia Institute of Technology has developed a novel approach to space electronics that could change how space vehicles and instruments are designed. The new capabilities are based on silicon-germanium (SiGe) technology, which can produce electronics that are highly resistant to both wide temperature variations and space radiation. http://phys.org/news210358590.html Technology Tue, 30 Nov 2010 16:56:47 EST news210358590 (PhysOrg.com) -- In preparation for NASA's next rover landing on the Red Planet, one Mars year away, an instrument studying the Martian atmosphere from orbit has begun a campaign. http://phys.org/news205049868.html Space & Earth Thu, 30 Sep 2010 07:18:23 EST news205049868 The red kite is now a commonly-seen bird of prey in the skies of the south-east, but a specially designed artificial blue kite promises a new way to make weather measurements. http://phys.org/news199108276.html Space & Earth Fri, 23 Jul 2010 12:51:32 EST news199108276 An increase in the variability of local conditions could do more to harm biodiversity than slower shifts in climate, a new study has found. http://phys.org/news182796799.html Biology Fri, 15 Jan 2010 16:53:54 EST news182796799 Temperature is an important factor in the spread of malaria and other mosquito-borne diseases, but researchers who look at average monthly or annual temperatures are not seeing the whole picture. Global climate change will affect daily temperature variations, which can have a more pronounced effect on parasite development, according to a Penn State entomologist. http://phys.org/news153931064.html Biology Sun, 15 Feb 2009 14:38:10 EST news153931064
