U-M team recovers ancient whale in Egyptian desert

...egrees Celsius to as low as 11 C, depending on the controlled ambient temperature within the chamber. "We have, on demand, reversibly demonstrated the widest range of metabolic flexibility that anyone has ever seen in a non-hibernating animal," Roth said. "The cool thing about this gas we're using, hydrogen s...

Canada approves marijuana-based pain spray

...for MS or neuropathic pain, a double-blind placebo controlled parallel group study demonstrated that Sativex provided significantly greater pain relief than placebo. Sativex also significantly reduced pain-related sleep disturbance. Principal components A product resulting from the pioneering research efforts ...

Researchers unlock mechanism creating jigsaw puzzle-like plant cells

...opment of leaf cell walls and leaf structures in a controlled and ordered way and that genetically over expressing one or the other leads to cells lacking the interlocking jigsaw puzzle appearance. While the researchers unlocked a fascinating mechanism of biochemical crosstalk that coordinates cells into tissu...

New tumor-suppressor gene discovered

... extends our understanding of how tissue growth is controlled both during normal development and during the formation of tumors, and it raises the possibility that the function of this gene may have important implications for the understanding and treatment of human cancers," says research leader Zhi-Chun Lai, ...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

...emselves that matter, but rather how the genes are controlled that makes a difference. The regulation of gene ex...ted into a protein. Many proteins are also tightly controlled through various post-translational modifications that activate or deactivate them. Translation is t...

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...hat help cells decide whether to grow or die via a controlled process called apoptosis. Cancer cells are usually defective in these regulatory pathways, so researchers hypothesized that structurally modified sphingolipid analogs might be even better at making cancer cells behave more normally. Merrill and his ...

UN votes to ban human cloning

...her sovereign States might want to permit strictly controlled applications of therapeutic cloning. The Declaration was a non-binding political statement, which would not affect Britain's position on the issue. China felt the prohibitions in the text might be "misunderstood" as covering all forms of cloning and...

Friendly bacteria in humans may protect against HIV

...loped and applied, the global spread of HIV can be controlled rapidly, effectively and safely." "The major roadblock in the development of this technology is the lack of financial support. Drug companies and venture capitalists are not interested because the beneficiary populations are infants and women in poo...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

...ical productivity in most of the world's oceans is controlled by the supply of nutrients to the surface water," wrote the authors, who are all affiliated with Stanford's School of Earth Sciences. "The Gulf of California contains some of the highest nutrient concentrations in the oceans and sustains highly eleva...

Protein prevents detrimental immune effects of bacterial sepsis

...gnals. Thus, the immune response must be carefully controlled to prevent damage to the host. Damazo et al. studied this balancing act by analyzing the effects of the bacterial toxin LPS on normal and annexin 1 knockout mice. Annexin 1 was chosen because it appears to be involved in the resolution phase of the ...

After a time-shift, mixed signals from the circadian clock

...mmalian behavior, physiology, and biochemistry are controlled by the central clock within a brain structure known as the suprachiasmatic nucleus (SCN). The clock is synchronized to environmental cycles of light and dark. It is well known, from everyday experience, that adjusting to new light schedules takes sev...

Brain May Be Less Plastic Than Hoped

...ifficult. Cortical injuries are not happening in a controlled fashion, and resulting data consequently are difficult to interpret,?he said. “But in the macaque, you can design lesions and test pharmaceuticals to sort out what kind of reorganization the brain is capable of after, say, a stroke. It's a powerful w...

Successful Test Of Single Molecule Switch Opens The Door To Biomolecular Electronics

...has been observed in molecules before but never in controlled conditions, never at low voltages, and not in a predictable way.?/p> Lindsay stresses that the main value of the finding is not in having found a molecule that could be developed into a working electrical switch, but in discovering some critical ...

Thai spice helps cut blood sugar swings

It's sold by vitamin and other specialty shops as Citrimax or Citrin, and is a featured ingredient in such dietetic aids as Herbalife's "...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

These antibiotics are basically natural chemicals (or derivatives of natural chemicals) produced by other bacteria or fung...

Future diabetes drugs may target new protein interaction

...ood is limited. But no one knew exactly how it was controlled or what else it might need in order to launch the sugar-making process. Sirtuin1, like its sirtuin relatives, is best known for removing molecular "decorations" on proteins that help organize DNA and restrict access to genes. It turns out that sirtu...
