 State College, Pa. (UPI) Jul 16, 2009 
U.S. scientists say a rapid evolution of the Y chromosome carried only by men has led to a rapid gene loss that might lead to the chromosome's disappearance.
Pennsylvania State University Associate Professor Kateryna Makova, who led the study, and researcher Melissa Wilson compared the DNA of the X and Y chromosomes in different classes of mammals. The researchers found that DNA ... read more 
Corvallis OR (SPX) Jul 17, 2009The findings of a major new study are consistent with gradual changes of current systems in the North Atlantic Ocean, rather than a more sudden shutdown that could lead to rapid climate changes in Europe and elsewhere. The research, based on the longest experiment of its type ever run on a "general circulation model" that simulated the Earth's climate for 21,000 years back to the height of ... more |

Washington DC (SPX) Jul 17, 2009Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council. The committee that wrote the report emphasized that these Arctic images show detailed melting and freezing processes ... more  
Kuwait City (UPI) Jul 16, 2009 A Kuwaiti company partly owned by the emirate's sovereign wealth fund is preparing to join other Gulf states in buying up agricultural land in Asia, part of a global land grab to ensure food security. Unlike the governments and corporations in the Gulf that have been acquiring vast tracts of arable land, mainly in poor countries of Africa, Asia, Latin America and Eastern Europe, to ... more 
Madison WI (SPX) Jul 17, 2009The study of human genetics has been a successful venture for researchers in recent years. Several million single-nucleotide polymorphisms (SNPs) have been identified from the whole-genome resequencing of multiple individuals, which have served as genetic markers to pinpoint genes controlling common human diseases. In contrast, the genome of a single cultivar or line has yet to be sequenced in ... more  
Cape Town (AFP) July 16, 2009The auction of a landmark mountain in Cape Town was postponed after a protest by 500 residents was broken up by police with rubber bullets and stun grenades, media reported Thursday. Angry residents who live in an informal settlement around the base of the 321-metre (1,053-foot) mountain known as The Sentinel in the Cape Town suburb of Hout Bay threw rocks at the hotel where the auction was ... more |

Beijing (UPI) Jul 16, 2009 The U.S. energy and commerce secretaries both warned of China's increasing emissions and called for greater cooperation between the two countries to thwart global warming in speeches here Wednesday. "Science has shown that we are altering the destiny of our planet. The consequences of what we are doing today will not be fully realized for at least 100 years," U.S. Secretary of Energy ... more 
The Hague (AFP) July 16, 2009The UN's highest court said Thursday it would hold hearings from September 14 into a border dispute between Argentina and Uruguay. The International Court of Justice (ICJ) said in a statement the public hearings would last until October 2. Argentina filed an application with the court in May 2006, accusing Uruguay of having unilaterally authorised the construction of two paper mills ... more 
Washington DC (SPX) Jul 17, 2009Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in Boulder, Colo., shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Nina and El Nino events in the tropical Pacific Ocean. The research may pave the way ... more 
Kingston, Ontario (UPI) Jul 16, 2009 Researchers at Canada's Queen's University say they have discovered that, in the plant world, big is not necessarily better. "Until now most of the thinking has suggested that to be a good competitor in the forest, you have to be a big plant," Professor Lonnie Aarssen, who led the study, said. "But our research shows it's virtually the other way around." The researchers focused ... more |
