Scientists looking across human, fly and worm genomes find shared biology

Researchers analyzing human, fly, and worm genomes have found that these species have a number of key genomic processes in common, reflecting their shared ancestry. The findings, appearing Aug. 28, 2014, in the journal Nature, offer insights into embryonic development, gene regulation and other biological processes vital to understanding human biology and disease.

Worms, flies and humans... Our common genomic legacy, key to understanding cell biology

This news release is available in Spanish.

Genomes accumulate changes and mutations throughout evolution. These changes have resulted in a huge diversity of species and in different traits between us. But animal cells, whether they are from a fly or a human, work similarly: they have common molecular mechanisms.

More wolf spiders feasting on American toads due to invasive grass, UGA study shows

Athens, Ga. – An invasive grass species frequently found in forests has created a thriving habitat for wolf spiders, who then feed on American toads, a new University of Georgia study has found.

Lifetime of fitness: A fountain of youth for bone and joint health?

ROSEMONT, Ill.—Being physically active may significantly improve musculoskeletal and overall health, and minimize or delay the effects of aging, according to a review of the latest research on senior athletes (ages 65 and up) appearing in the September issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS).

Dartmouth isolates environmental influences in genome-wide association studies

(Lebanon, NH 8/27/14)—Dartmouth cancer researchers developed and tested an advanced statistical model to evaluate the genetic and environmental interactions that contribute to disease as published yesterday in Human Genetics.

Group identity emphasized more by those who just make the cut

People and institutions who are marginal members of a high-status or well-esteemed group tend to emphasize their group membership more than those who are squarely entrenched members of the group, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

Drug represents first potential treatment for common anemia

(WASHINGTON, August, 27, 2014) – An experimental drug designed to help regulate the blood's iron supply shows promise as a viable first treatment for anemia of inflammation, according to results from the first human study of the treatment published online today in Blood, the Journal of the American Society of Hematology

Taking aim at added sugars to improve Americans' health

Now that health advocates' campaigns against trans-fats have largely succeeded in sidelining the use of the additive, they're taking aim at sugar for its potential contributions to Americans' health conditions. But scientists and policymakers are still wrangling over the best way to assuage the nation's insatiable sweet tooth, according to an article in Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society.

Promising new cancer therapy uses molecular 'Trash Man' to exploit a common cancer defense

While many scientists are trying to prevent the onset of a cancer defense mechanism known as autophagy, researchers at Virginia Commonwealth University Massey Cancer Center are leveraging it in a new therapy that causes the process to culminate in cell death rather than survival. The novel treatment strategy targets the p62 protein, which is often referred to as the "Trash Man" due to its role in disposing unwanted cellular proteins during autophagy.

Fighting prostate cancer with a tomato-rich diet

Men who eat over 10 portions a week of tomatoes have an 18 per cent lower risk of developing prostate cancer, new research suggests.

With 35,000 new cases every year in the UK, and around 10,000 deaths, prostate cancer is the second most common cancer in men worldwide.

Rates are higher in developed countries, which some experts believe is linked to a Westernised diet and lifestyle.

Leading scientists call for a stop to non-essential use of fluorochemicals

Fluorochemicals are synthetically produced chemicals, which repel water and oil and are persistent towards aggressive physical and chemical conditions in industrial processing. These characteristics have made the fluorochemicals useful in numerous processes and products, such as coatings for food paper and board.

Penn paleontologists describe a possible dinosaur nest and young 'babysitter'

Dinosaurs are often depicted as giant, frightening beasts. But every creature is a baby once.

A new examination of a rock slab containing fossils of 24 very young dinosaurs and one older individual is suggestive of a group of hatchlings overseen by a caretaker, according to a new study by University of Pennsylvania researchers.

Potential therapy for the Sudan strain of Ebola could help contain some future outbreaks

Ebola is a rare, but deadly disease that exists as five strains, none of which have approved therapies. One of the most lethal strains is the Sudan ebolavirus (SUDV). Although not the strain currently devastating West Africa, SUDV has caused widespread illness, even as recently as 2012. In a new study appearing in the journal ACS Chemical Biology, researchers now report a possible therapy that could someday help treat patients infected with SUDV.

How to prevent organic food fraud

A growing number of consumers are willing to pay a premium for fruits, vegetables and other foods labelled "organic", but whether they're getting what the label claims is another matter. Now scientists studying conventional and organic tomatoes are devising a new way to make sure farms are labelling their produce appropriately. Their report, which appears in ACS' Journal of Agricultural and Food Chemistry, could help prevent organic food fraud.

Piglet weaning age no bar to litter frequency

University of Adelaide research has shown that piglets can be weaned later with no negative effects on sow birthing frequency.

The outcome of the study at the University's Roseworthy campus, published in the journal Animal Reproduction Science, is an important finding for pig producers. It allows improvements in piglet health and welfare without loss of production.
