Migrating birds sprint in spring, but take things easy in autumn

Science Daily - Tue, 02/09/2014 - 1:32pm
Passerine birds, also known as perching birds, that migrate by night tend to fly faster in spring than they do in autumn to reach their destinations. This seasonal difference in flight speed is especially noticeable among birds that only make short migratory flights, research shows. As short-distance migratory birds, they have the luxury to wait until winds are just right.

From silk tunics to relics: Development of early relic worship

Science Daily - Tue, 02/09/2014 - 1:32pm
Archaeologists working with restorers are preserving and studying 4th-century tunics ascribed to St. Ambrose. In the course of examining these valuable silk garments, they have made surprising scholarly discoveries regarding the development of early relic worship.

Risk of diabetes in children, adolescents exposed to antipsychotics: Danish 12-year case-control study

Science Daily - Tue, 02/09/2014 - 1:32pm
Children and adolescents pegged with a psychiatric diagnosis had an increased risk of developing diabetes if they were exposed to antipsychotics. Using data from the nationwide Danish registers, a group of researchers studied 48,299 children and adolescents with psychiatric disorders to document the frequency and possible predictors of type II diabetes, defined by treatment with an oral antidiabetic drug.

Rainfall monitoring: Mobile phones are taking over

Science Daily - Tue, 02/09/2014 - 1:32pm
Agriculture, water resource management, drought and flood warnings, etc.: rainfall monitoring is vital in many areas. But the observation networks remain insufficient. This is not the case for antennas for mobile telephones, which cover 90% of the world's inhabited areas. Besides transmitting radio signals, they record signal disturbances, which are partly due to precipitation, in order to monitor the quality of networks.

Seismic hazards reassessed in the Andes

Science Daily - Tue, 02/09/2014 - 1:29pm
Although being able to predict the date on which the next big earthquake will occur is still some way off becoming a reality, it is now possible to identify the areas where they will occur. Researchers have just measured the current deformation in the northern part of the Andes for the first time using GPS, where the tectonics of the Pacific and South American plates govern the high seismic activity in the region. The scientists then identified the areas where the fault, located at the interface of these two plates, is capable of generating large earthquakes or not.

Cultivating biodiversity: Sorghum example

Science Daily - Tue, 02/09/2014 - 1:29pm
It is difficult to distinguish the human impact on the effects of natural factors on the evolution of crop plants. A Franco-Kenyan research team has managed to do just that for sorghum, one of the main cereals in Africa. The scientists demonstrated how three societies living on the slopes of Mount Kenya have shaped the geographic distribution and structure of the genetic diversity of local varieties.

Scientists obtain new data on the weather 10,000 years ago from sediments at the bottom of a lake in Sierra Nevada

Science Daily - Tue, 02/09/2014 - 1:29pm
During the early phase of the Holocene (10.000 – 6.000 years ago) the climate in the Iberian Peninsula was rather more humid than it currently is, according to new research.

Mechanical ventilation a key indicator for pre-term children's maths problems

Science Daily - Tue, 02/09/2014 - 1:29pm
Both the length of time spent in hospital after birth and the use of mechanical ventilation are key indicators of reduced mathematical ability in preterm children, researchers report. Impairments in mathematic abilities are common in very preterm children. Earlier studies of children who are born very preterm (before 32 weeks of gestational age) have shown that they have a 39.4% chance of having general mathematic impairment, compared to 14.9% of those born at term (39 to 41 weeks).

Childhood trauma could lead to adult obesity

Science Daily - Tue, 02/09/2014 - 1:29pm
Being subjected to abuse during childhood entails a markedly increased risk of developing obesity as an adult. This is the conclusion of a meta-analysis carried out on previous studies, which included a total of 112,000 participants.

Skin cells can be engineered into pulmonary valves for pediatric patients

Science Daily - Tue, 02/09/2014 - 1:22pm
Researchers have found a way to take a pediatric patient’s skin cells, reprogram the skin cells to function as heart valvular cells, and then use the cells as part of a tissue-engineered pulmonary valve. It is estimated that nearly 800 patients per year could potentially benefit from bioengineered patient-specific pulmonary valves.

AMD Releases New Tonga GPU, Lowers 8-core CPU To $229

Slashdot - Tue, 02/09/2014 - 1:13pm
Vigile (99919) writes AMD looks to continue addressing the mainstream PC enthusiast and gamer with a set of releases into two different component categories. First, today marks the launch of the Radeon R9 285 graphics card, a $250 option based on a brand new piece of silicon dubbed Tonga. This GPU has nearly identical performance to the R9 280 that came before it, but includes support for XDMA PCIe CrossFire, TrueAudio DSP technology and is FreeSync capable (AMD's response to NVIDIA G-Sync). On the CPU side AMD has refreshed its FX product line with three new models (FX-8370, FX-8370e and FX-8320e) with lower TDPs and supposedly better efficiency. The problem of course is that while Intel is already sampling 14nm parts these Vishera-based CPUs continue to be manufactured on GlobalFoundries' 32nm process. The result is less than expected performance boosts and efficiency gains. For a similar review of the new card, see Hot Hardware's page-by-page unpacking.

Kernel Developer Dmitry Monakhov Arrested For Protesting Ukraine Invasion

Slashdot - Tue, 02/09/2014 - 12:53pm
sfcrazy (1542989) writes, based on a report from Ted T'so, that Kernel developer Dmitry Monakhov was detained for 15 days for disobeying a police officer. The debacle came about when Monakhov decided to protest the recent invasion into Ukraine by Russian armed forces. Monakhov is using Twitter to keep people informed about his experience with the Russian judicial system; a human translator can probably do a better job than Google in this case.
