Thirsty wheat needed new water management strategy in ancient China
- ScienceDaily
- 22/11/10 20:40
Research shows that a practice of purposeful water management, or irrigation, was adopted in northern China about 4,000 years ago as part of an effort to grow new grains that had been introduced from southwest Asia. But the story gets more complex from there. Wheat and barley arrived on the scene at about the same time, but early farmers only used water management techniques for wheat. The results...

Mimicking life: Breakthrough in non-living materials
- ScienceDaily
- 22/11/10 17:42
Researchers have discovered a new process that uses fuel to control non-living materials, similar to what living cells do. The reaction cycle can easily be applied to a wide range of materials and its rate can be controlled -- a breakthrough in the emerging field of such reactions. The discovery is a step towards soft robotics; soft machines that can sense what is happening in their environment...
Research reveals how a common bacterium may spread from the intestine
- ScienceDaily
- 22/11/10 17:42
A typical gut bacterium that can spread through the body and cause a serious infection resists natural immune defenses and antibiotics by enhancing its protective outer layer, known as the cell envelope, according to a new study. The finding suggests possible new ways to target these bacterial infections.
The world will probably warm beyond the 1. 5-degree limit, but peak warming can be curbed
- ScienceDaily
- 22/11/10 17:42
The world's current climate pledges are insufficient to keep global warming below 1.5 degrees Celsius. We will overshoot. In new research, scientists chart several potential courses in which the overshoot period is shortened, in some cases by decades.
The gut microbiome's supersized role in shaping molecules in our blood
- ScienceDaily
- 22/11/10 17:42
Scientists have shown which blood metabolites are associated with the gut microbiome, genetics, or the interplay between both. Their findings have promising implications for guiding targeted therapies designed to alter the composition of the blood metabolome to improve human health.
Death of a star reveals midsize black hole lurking in a dwarf galaxy
- ScienceDaily
- 22/11/10 17:42
An intermediate-mass black hole lurking undetected in a dwarf galaxy revealed itself to astronomers when it gobbled up an unlucky star that strayed too close. The shredding of the star, known as a 'tidal disruption event' or TDE, produced a flare of radiation that briefly outshone the combined stellar light of the host dwarf galaxy and could help scientists better understand the relationships...
Researchers pinpoint potential treatment for lethal childhood cancer
- ScienceDaily
- 22/11/10 17:42
Researchers discovered that by blocking the production of an enzyme called DHODH, they were able to halt the growth of MYC gene-amplified medulloblastoma in mouse models, the most aggressive subtype of this cancer.
Detecting the undetected: Measuring levels of three proteins in the blood can aid detection of undiagnosed prediabetes
