Live fast, die young true for forests too

... add the most new growth each year -- also tend to die young, according to a U.S. Geological Survey (USGS) study published in a recent issue of the journal Ecology Letters. This discovery could help scientists predict how forests will respond to ongoing and future environmental changes. "One implication...

Dead zone area in Gulf could be increasing, researchers say

...h in this area can be "stressed," meaning they can die or, at the very least, move to other areas, which adversely affects fishermen in the dead zone region. "Bottom-dwelling marine life, where some of the most intense hypoxia levels are, can easily die," he says. "This area is of immense importance to...

Increased risk of osteoporosis associated with gene that one in five people have

...that more than 20 percent of hip fracture patients die within a year. Additionally, about 30 percent of hip fracture patients will fracture the opposite hip, up to 25 percent may require long-term nursing home care and only 40 percent fully regain their prefracture level of independence. Given the serio...

Researchers make gains in understanding antibiotic resistance

...ic-resistant infections each year; 90,000 patients die annually from such infections. In their experiments, Steitz and his colleagues used x-ray crystallography to do high-resolution structural analyses of the large ribosomal subunits bound to a number of the MLSBK antibiotics. In this analytical techni...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...hins and porpoises--or cetaceans--are estimated to die every year from entanglement in fishing gear, more than from any other cause. Chemist Norm Holy from Pennsylvania, fisheries biologist Ed Trippel from Canada, and fisherman Don King from Massachusetts joined forces and developed gear to help marine m...

Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leukemia Prognosis

...roughout life as red and white cells and platelets die and must be replaced. HSCs are also needed to rebuild the blood system of patients undergoing chemotherapy and radiation for cancer. Opferman completed work on this project while a member of Stanley Korsmeyer's laboratory at the Dana-Farber Cancer In...

"Now that the target for histatin has been identified, we can design a better protein that will be even more effective in binding and holding the channel open, causing even better and more rapid killing of the fungus," said E...

White Blood Cell 'Waste Disposal' System Plays Critical Regulatory Role

...ances. Neutrophils have a short lifespan and often die via a programmed cell death pathway called apoptosis within a matter of hours. Dying neutrophils are recognized and ingested by cells in the body tissues called phagocytes. Although the specific mechanisms that regulate the proper ratios of neutroph...

Some Brain Cells 'Change Channels' To Fine-tune The Message

Test for early detection of prostate cancer shows promise

Novel gene-silencing nanoparticles shown to inhibit Ewing's sarcoma

...ing's family tumors and 95 percent with metastases die as a result of their disease. Scientists now recognize that Ewing's sarcoma results when two chromosomes break and trade their genetic content in what's technically called a "translocation," activating the oncogene EWS-FLI1 which triggers the tumor ...

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

...olecules that 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. ...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ns share something in common with the neurons that die in people with diseases such as Alzheimer's and Parkinson's: both have unusually low levels of a protein called UCHL1. "It would be ironic if the shortfall in a same gene brokered the path to brain disease or rejuvenation," says Nottebohm, who is Do...

Study reveals dramatic difference between breast cancers in US and Africa

Protein Discovery Could Unlock The Secret To Better TB Treatment

...istant TB. In England and Wales around 400 people die each year from the disease. The top challenge for TB control in the European region is multidrug-resistant TB (MDR-TB). Eight per cent of the bacteria causing TB in patients are resistant to one or more drugs and one per cent show multidrug resistanc...

Cellular Defects in Premature Aging Disease are Reversible

... the leading killer, and affected children usually die before they reach their late teens. Less than two years ago, NIH-led researchers discovered that the genetic basis for HGPS is a single mutation in the gene encoding lamin A. Lamin A is a critical structural protein that acts as the scaffolding whic...
