Serengeti patrols cut poaching of buffalo, elephants, rhinos

...set fishing limits. Estimates are based on a ratio comparing the number of fish caught in an area with the total number of hours of fishing ?the unit-of-effort ?by all the vessels in that area. In the Serengeti, which has a 50-year-record of arrests and patrols, the scientists divided the number of poacher...

For super-obese patients, duodenal switch beats gastric bypass

P(acman) takes a bite out of deciphering Drosophila DNA

...the message from another gene. “You are really comparing apples and oranges when you do this,?said Bellen. The technique is also limited to small DNA chunks. “Koen set out to develop a new transgenesis system using the three techniques,?said Bellen. The bacterial artificial chromosome, or BAC, he use...

New genetic analysis forces re-draw of insect family tree

...re distantly related to these three groups. "By comparing genetic information from 185 genes that were sequenced in species from all of these groups, we found that in fact flies and moths are most closely related to beetles, and more distantly related to bees. "This sheds new light on a large number of e...

Jumping gene could provide non-viral alternative for gene therapy

...ity of Hawaii and a corresponding author. "But by comparing different transposons, we showed Sleeping Beauty is far inferior to piggyBac." Scientists have used viruses as a gene delivery mechanism for more than 20 years because of their adeptness at getting inside cells and inserting themselves in DNA. But ...

Study shows interruption of antiretroviral therapy increases risk of disease and death

...Management of Anti-Retroviral Therapies, or SMART, comparing two treatment strategies for people with human immunodeficiency virus (HIV). Findings from the study, published in the November 30 New England Journal of Medicine, demonstrate the value of continuous antiretroviral therapy. As HIV/AIDS has evolved i...

Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...he sequence of the aqp2 gene from the mutant mice, comparing it to the gene from other normal mice, and found a single base pair had changed." The change swaps the amino acid serine for the amino acid leucine at a key position in the protein. Serine can undergo phosphorylation, a form of chemical modificatio...

Scientists' cell discovery unearths evolutionary clues

...re able to build the family tree by amplifying and comparing highly conserved genes from all known species of social amoeba. The existing family tree of the social amoeba was based on how the multicellular structures of each species look on the outside. However, this tree was completely uprooted by the mol...

Results with newer bladeless LASIK equivalent to standard microkeratome LASIK

A Mayo Clinic study comparing femtosecond (bladeless) and mechanical microkeratome LASIK surgeries has found equal results from both types six months post-surgery, using a variety of vision and eye health measurements. The study's findings will be presented next week in three abs...

Embryos exposed in 3-D

...D Cell Therapy, Pall Life Sciences, presented data comparing the Pall Filter Harvest System to a traditional open-system, density gradient, centrifuge-based method for isolation of mononuclear cells (MNC) from whole blood. The Pall Filter Harvest System was found to significantly reduce processing time; it ca...

New technology enables faster, more efficient cell harvest: Cell therapy meeting study

The Pall Filter Harvest System was found to significantly reduce processing time; it ca...

Do angry men get noticed?

By comparing how quickly human facial expressions of different types are detected in a crowd of neutral faces, researchers have demonstrated that male angry faces are a priority for visual processing ?particularly for male observers. The findings are reported by ...

UCSD researchers develop 'smart petri dish'

... blood samples from a patient onto the crystal and comparing them to normal blood samples." In addition, says Michael Schwartz, a postdoctoral scholar in Sailor's laboratory and the first author of the paper: "The potential of our technique for fundamental studies of cell toxicity is exciting, Since we can mon...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...then validated the genomic test in 129 patients by comparing the test's predictions with the patient's actual outcomes. The test predicted their risk of recurrence with 90 percent accuracy, the study showed. If proven to be effective in the clinical trial, the test will replace the current method of assessin...

Wild vs. lab rodent comparison supports hygiene hypothesis

In a study comparing wild rodents with their laboratory counterparts, r...uke researchers decided to study the hypothesis by comparing the immune systems of wild house mice and common rats to laboratory mice and rats. The strength of t...

Even a little cooling helps after cardiac arrest

Study finds that a woman's chances of having twins can be modified by diet

...termined by a combination of diet and heredity. By comparing the twinning rate of vegan women, who consume no animal products, with that of women who do eat animal products, Gary Steinman, MD, PhD, an attending physician at Long Island Jewish (LIJ) Medical Center in New Hyde Park, NY, found that the women who ...

Researchers identify human DNA on the fast track

...enome last year, geneticists have spent many hours comparing human DNA sequences to those of our closest evolutionary relative, looking for the differences that distinguish the two species. Now a team of researchers has found the human DNA sequence with the most dramatically increased rate of change. The func...

NHGRI announces latest sequencing targets
