3-D printed ovaries produce healthy offspring
3-D printed bioprosthetic mouse ovaries restored fertility in infertile mice and produced healthy mouse pups. The mothers also were able to nurse their pups. The research is targeted to women whose cancer treatments impaired their fertility and hormone production. The ovaries are constructed of 3-D printed scaffolds that house immature eggs and were successful in boosting hormone production and restoring fertility.

Scientists study atmospheric waves radiating out of hurricanes
Researchers believe they have found a new way to monitor the intensity and location of hurricanes from hundreds of miles away by detecting atmospheric waves radiating from the centers of these powerful storms.

New 'styrofoam' planet provides tools in search for habitable planets
Researchers at Lehigh University have discovered a new planet orbiting a star 320 light years from Earth that has the density of styrofoam. This 'puffy' exoplanet may hold opportunities for testing atmospheres that will be useful when assessing future planets for signs of life. The research, 'KELT-11b: A Highly Inflated Sub-Saturn Exoplanet Transiting the V+8 Subgiant HD 93396,' appears in The Astronomical Journal May 2017 issue.

Lessons from Ebola: New approach improves disease outbreak management
A new approach could quickly identify the most effective way to manage disease outbreaks -- an advance that could save lives. Developed by scientists using insights from the 2014 Ebola outbreak, the method pinpoints critical pieces of missing information required to improve management decisions during an outbreak. A paper describing the approach will be published in the journal Proceedings of the National Academy of Sciences during the week of May 15, 2017.

Growing plants and scientists: Hydroponic gardening program wins over students
Elementary-age students -- primarily African-American, Hispanic and English Language Learners -- developed positive attitudes toward science, less anxiety, and greater self-confidence after participating in an after-school program where they grew fruits and vegetables using soil-less, hydroponic technology.

More genes turned on when plants compete
Some people travel to northern California for wine. However, Maren Friesen, Michigan State University plant biologist, treks to the Golden State for clover. The lessons of plant diversity and competition learned from a clover patch, which are featured in a special issue of the Journal of Ecology, can potentially unlock secrets on plant interactions around the globe.

How satellite data led to a breakthrough for Lake Erie toxic algal blooms
With the growing frequency and magnitude of toxic freshwater algal blooms becoming an increasingly worrisome public health concern, Carnegie scientists Jeff Ho and Anna Michalak, along with colleagues, have made new advances in understanding the drivers behind Lake Erie blooms and their implications for lake restoration. The work is published in two related studies.

Grassy beginning for earliest Homo
Following the discovery of the Ledi-Geraru jaw, an environmental study of the eastern African Plio-Pleistocene was conducted to investigate the long-standing hypotheses that the transition from Australopithecus to Homo was linked to the spread of more open and arid environments. Data indicate that the Ledi-Geraru Research Project area in the Lower Awash Valley and Omo-Turkana Basin were largely similar, but important environmental differences existed at the time of earliest Homo (~ 2.8 Ma).

Nano fiber feels forces and hears sounds made by cells
Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells. The device is a nano-sized optical fiber that detects forces down to 160 femtonewtons and sound levels down to -30 decibels. Applications include measuring bio-activity at the single cell level, or ultra-sensitive mini stethoscopes to monitor cellular acoustics in vivo.

Fossil 'winged serpent' is a new species of ancient snake, Penn doctoral student finds
An ancient sink hole in eastern Tennessee holds the clues to an important transitional time in the evolutionary history of snakes. Among the fossilized creatures found there, according to a new paper co-authored by a University of Pennsylvania paleontologist, is a new species of snake that lived 5 million years ago.

Hafnia dons a new face
As computer chips become smaller, faster and more powerful, their insulating layers must also be much more robust -- currently a limiting factor for semiconductor technology. A collaborative University of Kentucky-Texas A&M University research team says this new phase of hafnia is an order of magnitude better at withstanding applied fields.

Migratory seabird deaths linked to hurricanes
Stronger and more frequent hurricanes may pose a new threat to the sooty tern, a species of migratory seabird found throughout the Caribbean and Mid-Atlantic, a new Duke-led study reveals. The study is the first to map the birds' annual migratory path and demonstrate how its timing and trajectory place them in the direct path of hurricanes moving into the Caribbean from the Atlantic. Climate change may increase the risk.

Oldest buckthorn fossilized flowers found in Argentina
Around 66 million years ago, at the end of the Cretaceous period, a giant asteroid crashed into the present-day Gulf of Mexico, leading to the extinction of the non-avian dinosaurs. How plants were affected is less understood, but fossil records show that ferns were the first plants to recover many thousands of years afterward. Now, a team including Cornell researchers reports the discovery of the first fossilized flowers from South America, and perhaps the entire Southern Hemisphere, following the extinction event.
