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.

Extreme Pacific Sea Level Events to Double in Future
Many tropical Pacific island nations are struggling to adapt to gradual sea level rise stemming from warming oceans and melting ice caps. Now they may also see much more frequent extreme interannual sea level swings. The culprit is a projected behavioral change of the El Niño phenomenon and its characteristic Pacific wind response, according to recent computer modeling experiments and tide-gauge analysis by scientists Matthew Widlansky and Axel Timmermann at the International Pacific Research Center, University of Hawai'i at Mānoa, and their colleague…

Bond Gene in Fruit Flies Controls Fertility of Rival Males
For many animals, pheromones, which are chemical cues used for communication, guide important decisions such as whom to mate and whom to fight. New research from scientists at the University of Hawai'i - Mānoa's (UHM) Pacific Biosciences Research Center (PBRC), a newly integrated research unit of the School of Ocean and Earth Science and Technology (SOEST), identified a single gene in fruit flies (Drosophila) that controls male pheromone production, male fertility, and, surprisingly, the fertility of rival males. …

Research Shows Catastrophic Invertebrate Extinction in Hawai'i And Globally
Hawai'i has been called the "extinction capital of the world." But, with the exception of the islands' birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawai'i's formerly spectacularly diverse and unique biota. A team of researchers, including scientists from the Pacific Biosciences Research Center (PBRC) at the University of Hawai'i at Mānoa, the Bishop Museum in Honolulu, Howard University…

Parental Experience May Help Coral Offspring Survive Climate Change
A new study from scientists at the University of Hawai'i - Mānoa's (UHM) Hawai'i Institute of Marine Biology (HIMB) reveals that preconditioning adult corals to increased temperature and ocean acidification resulted in offspring that may be better able to handle those future environmental stressors. This rapid trans-generational acclimatization may be able to "buy time" for corals in the race against climate change.

New Research Uncovers Brain Circuit in Fruit Fly That Detects Anti-aphrodisiac
New research, published today in eLife, identified the neural circuit in the brain of the fruitfly (Drosophila melanogaster) that is responsible for detecting a taste pheromone, which controls the decision of male flies to mate with females.

Researchers Discover Deep Sea Sharks Are Buoyant
In a study published recently, scientists from the University of Hawai'i - Mānoa (UHM) and University of Tokyo revealed that two species of deep-sea sharks, six-gill and prickly sharks, are positively buoyant - they have to work harder to swim downward than up, and they can glide uphill for minutes at a time without using their tails.

Plants May Run Out of Time to Grow Under Ongoing Climate Change
A key potential 'benefit' of global warming--namely, that plants at northern latitudes will thrive in a warmer world--is challenged by a new study released by University of Hawai'i scientists today.

Comet Wild 2: A Window into the Birth of the Solar System?
Our solar system, and other planetary systems, started as a disk of microscopic dust, gas, and ice around the young Sun. The amazing diversity of objects in the solar system today - the planets, moons, asteroids, and comets - was made from this primitive dust. NASA's Stardust mission returned to Earth with samples of comet Wild 2, a comet that originated outside the orbit of Neptune and was subsequently kicked closer to Earth's orbit in 1974 when Jupiter's gravity altered Wild 2's orbit.
