It takes a 'consortium': Researchers develop metabolic engineering technique
- ScienceDaily
- 19/9/11 23:46
For years, scientists have explored ways to alter the cells of microorganisms in efforts to improve how many products are made, including medicines, fuels, and even beer. But altering the genetic and regulatory processes that take place within cells presents challenges. Now bioengineers is working with a team of researchers to engineer microbial consortia, wherein cell subpopulations are...
Facebook wants to fight teen suicide. Experts aren’t sure they’re doing it right
Suicide among young people is on the rise, and many point to social media as the cause.
For the first time, a timeline reveals what happened in the minutes and hours after the asteroid crash that killed the dinosaurs
The dinosaurs' extinction was spurred by an asteroid that struck Earth. By studying the crater, scientists now know what happened after the...
Black hole at the center of our galaxy appears to be getting hungrier

The enormous black hole at the center of our galaxy is having an unusually large meal, and researchers don't know why. 'We have never seen anything like this in the 24 years we have studied the supermassive black hole,' said a professor of physics and astronomy.
Cell-mostly internet users place privacy burden on themselves
- ScienceDaily
- 19/9/11 22:52
Do data privacy concerns disproportionately affect people who access the internet primarily through cell phones? New research indicates that cell-mostly internet users are more likely to be exploited online, be victims of data leaks, have less knowledge of phone security practices, and have attitudes of resignation with regard to their agency over their data.
Cancer survival in high income countries is improving, but international disparities persist
- ScienceDaily
- 19/9/11 22:52
An observational study including 3.9 million cancer cases in seven high-income countries between 1995-2014 finds that survival of seven cancers is generally improving, although the overall level and pace of improvement varies between countries and for each cancer type.
Gene therapy helps functional recovery after stroke
- ScienceDaily
- 19/9/11 22:52
A new gene therapy turns glial cells -- abundant support cells in the brain -- into neurons, repairing damage that results from stroke and significantly improving motor function in mice.
Experiments at temperature of sun offer solutions to solar model problems
- ScienceDaily
- 19/9/11 22:52
The theoretical model that astrophysicists have used for 40 years to determine the behavior and future of the sun is broken. It seems fixable, however, with information from experiments at Sandia's Z machine, done at the temperature of the sun, that can accurately determine how much energy the sun's components allow to pass through them.
UK still behind in cancer survival despite recent surge
Big improvement in past two decades fails to close gap with likes of Australia and CanadaCancer survival rates in the UK have improved markedly over recent decades but still lag behind those of comparable countries, a major research exercise has shown.The study looked at one-year and five-year survival of cancer patients in Australia, Canada, Denmark, Ireland, New Zealand, Norway and the UK...
Black hole at the center of our galaxy appears to be getting hungrier
The enormous black hole at the center of our galaxy is having an unusually large meal of interstellar gas and dust, and researchers don't yet understand why.
Meet Rudy, the high-wire robot that could be N.L.'s next big invention
Averro Robotics and Technology created Rudy for a very specific but important job. But if you have a fear of heights, you may not want to see...
A precise chemical fingerprint of the Amazon
In 2017, Scot Martin, the Gordon McKay Professor of Environmental Science and Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), envisioned a novel drone-based chemical monitoring system to track the health of the Amazon in the face of global climate change and human-caused deforestation and burning.
Topography could save sensitive saguaros as climate changes
The iconic saguaros on Tumamoc Hill served as harbingers in new research which sought to predict how the desert species will fare in the hotter, drier climate of the future and how topography might mitigate the effects of climate change.
More than 40,000 years ago, giant kangaroos roamed Australia. Their jaws were surprisingly similar to those of pandas, a new study found.
Extinct Australian kangaroos weighed more than 250 pounds and had powerful jaws to crunch through tough vegetation, much like today's giant...
New study examines how species colonize habitats opened by anthropogenic land cover change
As plants expand into new open habitats, geographical and climatic factors may matter more than species-specific traits, according to a study published September 11, 2019 in the open-access journal PLOS ONE by Miki Nomura of the University of Otago in New Zealand, and colleagues.
Professor's research paints picture of #MeToo movement's origins
On Oct. 15, 2017, actress Alyssa Milano sparked a firestorm on social media when she asked her Twitter followers to reply "me too" if they had ever been sexually harassed or assaulted. (Social justice activist Tarana Burke founded the "Me Too" movement more than 10 years ago as a way to help sexual assault survivors heal.) What followed were 1.5 million responses—many from sexual assault...
Hoary bat numbers declining at rate that suggests species in jeopardy in Pacific Northwest
The hoary bat, the species of bat most frequently found dead at wind power facilities, is declining at a rate that threatens its long-term future in the Pacific Northwest, according to a novel and comprehensive research collaboration based at Oregon State University—Cascades.
Nerve-like 'optical lace' gives robots a human touch
- ScienceDaily
- 19/9/11 21:12
A new synthetic material that creates a linked sensory network similar to a biological nervous system could enable soft robots to sense how they interact with their environment and adjust their actions accordingly.
Climate change may cut soil's ability to absorb water
- ScienceDaily
- 19/9/11 21:12
Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a new study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.
