2 Y Genes Can Replace the Entire Y Chromosome for Assisted Reproduction in Mice

Published: November 21, 2013.
Released by University of Hawaii at Manoa  

The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y.

A Cold Cosmic Mystery Solved
In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.

Ocean-scale Dataset Allows Broad View of Human Influence on Pacific Coral Reef Ecosystems
As man-made threats to coral reefs mount and interest in conserving reef ecosystems grows, scientists have turned to studying extremely remote and uninhabited reefs in an effort to understand what coral reefs would be like in the absence of humans. A number of islands and atolls in the Pacific Ocean remain virtually untouched by human influence, situated hundreds of kilometers from the nearest human populations.

New Research Predicts a Doubling of Coastal Erosion by Mid-century in Hawai'i
Chronic erosion dominates the sandy beaches of Hawai'i, causing beach loss as it damages homes, infrastructure, and critical habitat. Researchers have long understood that global sea level rise will affect the rate of coastal erosion. However, new research from scientists at the University of Hawaii - M?noa (UHM) and the Hawai'i Department of Land and Natural Resources brings into clearer focus just how dramatically Hawai'i beaches might change.

New Research Finds Oceanic Microbes Behave in a Synchrony Across Ocean Basins
Researchers from the University of Hawai'i - M?noa (UHM) and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats - the nutrient-rich waters off California and the nutrient-poor waters north of Hawai'i. Furthermore, in each location, the dominant photoautotrophs - light-loving bacteria that need solar energy to help them photosynthesize food from inorganic substances - appear to initiate a cascade effect wherein the other major groups of…

Heavy Rainfall Events Becoming More Frequent on Big Island, Finds New Study
A recent study by University of Hawai'i - Manoa (UHM) researchers determined that heavy rainfall events have become more frequent over the last 50 years on Hawai'i Island. For instance, a rare storm with daily precipitation of nearly 12 inches, occurring once every 20 years by 1960, has become a rather common storm event on the Big Island of Hawai'i - returning every 3-5 years by 2009.

HURL And NOAA Team Discover Intact 'Ghost Ship' Off Hawai'i
Researchers from the University of Hawai'i (UH) and NOAA's Office of National Marine Sanctuaries today announced the discovery of an intact "ghost ship" in 2,000 feet of water nearly 20 miles off the coast of Oahu. Sitting upright, its solitary mast still standing and the ship's wheel still in place, the hulk of the former cable ship Dickenson, later the USS Kailua, was found on the seabed last year on a maritime heritage submersible mission with the UH Hawai'i Undersea Research Laboratory's (HURL)…

El Nino's 'Remote Control' on Hurricanes in the Northeastern Pacific
El Niño, the abnormal warming of sea surface temperatures in the Pacific Ocean, is a well-studied tropical climate phenomenon that occurs every few years. It has major impacts on society and Earth's climate - inducing intense droughts and floods in multiple regions of the globe. Further, scientists have observed that El Niño greatly influences the yearly variations of tropical cyclones (a general term which includes hurricanes, typhoons and cyclones) in the Pacific and Atlantic Oceans. However, there is a mismatch in both timing…

Another Human Footprint in the Ocean
Human-induced changes to Earth's carbon cycle - for example, rising atmospheric carbon dioxide and ocean acidification - have been observed for decades. However, a study published this week in Science showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle.
