Agent slows aging in mice

...fed a normal diet and NDGA so far have survived in significantly greater numbers than mice on a normal diet. Scientists measured the difference at a point called median lifespan, when half the control mice had died of natural causes associated with aging. “This is the first time to my knowledge when an agent h...

Enzyme delivered in smaller package protects cells from radiation damage

...were counted. The MnSOD transfected cells were significantly more resistant to ionizing radiation than the non-tranfected cells. However, there was no significant difference in survival between MnSOD-minicircle and MnSOD full plasmid transfected cells. According to Dr. Greenberger, whose group is currently con...

Releasing fish for the future

...aul Butcher have shown that mortality rates can be significantly improved through changed practices. Key recommendations from an initial two-year project are that fishers should Cut the line on fish that swallow hooks Remove hooks caught in the fish’s mouth Minimise air exposure Use landing nets w...

Soils offer new hope as carbon sink

... measured gases given off from the soils and found significantly lower emissions of carbon dioxide and nitrous oxide (a greenhouse gas more than 300 times as potent as carbon dioxide). NSW DPI environmental scientist Steve Kimber said an added benefit for both the farmer who applies agrichar and the environment...

Old memory traces in brain may trigger chronic pain

... In animal studies, D-Cycloserine appeared to significantly diminish the emotional suffering from pain as well as reduce the sensitivity of the formerly injured site. It also controlled nerve pain resulting from chemotherapy, noted Apkarian, who is a member of the Robert H. Lurie Comprehensive Cancer Center ...

Dirty snow may warm Arctic as much as greenhouse gases

...lting to expose underlying sea ice or soil that is significantly darker than the snow. The darker surfaces absorb sunlight more rapidly than snow, causing additional warming. This cycle causes temperatures in the polar regions to rise as much as 3 degrees Celsius during some seasons, the scientists say. “Once t...

In a paper appearing online this week ahead of the regular publication by the Proceedings of the National Academy of Sciences (PNAS), the five-member team reports that agrichemicals bind to and block connections to specific recepto...

In mice, drug protects against diabetes and atherosclerosis

Study investigates 'divorce' among Galapagos seabirds

...ivorce after a few breeding seasons. Since males significantly outnumber females in the colony studied, there are plenty of bachelors available if the female has a wandering eye. “Our study population has 50 percent more males than females, creating the opportunity for females to trade a current mate, which m...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

...had performed. The cell-seeded constructs showed a significantly higher blockage-free rate than unseeded controls (55 percent versus 0 percent). In addition, at eight weeks, there was an extensive remodeling of the MDSC-seeded polymer by surrounding tissue, exhibiting tissue formation that is consistent with a mat...

Research finds that circadian rhythms dominate all life functions

.... The research also shows that gene oscillation is significantly more organized when mammals are exposed to regular periods of day and night. Oscillation can become chaotic in states of consistent lighting or lack of lighting, but it never stops. Comparing the complex system in which the genes function to an AC ...

It appears that religious families in the north, specifically concerned fathers and brothers, do a much better job protecting their daughters from predatory males than do those in the south....

Scientists close in on missing carbon sink

...dels. The scientists found that most of the models significantly underestimated the airborne concentrations of carbon dioxide in northern latitudes, especially in the summer, when plants take in more carbon. The aircraft samples show that northern forests absorb only 1.5 billion tons of carbon a year, which is alm...

Antarctic icebergs -- Hotspots of ocean life

They may also play a surprising role in global climate change. “One important consequence of the increased biological productivity is that fre...
