Optimization for self-production may explain mysterious features of the ribosome

(Harvard Medical School) New study explains previously mysterious characteristics of ribosomes, the protein production factories of the cell. Researchers mathematically demonstrate that ribosomes are precisely structured to build themselves as quickly as possible to support efficient cell growth.

High-fat diet in pregnancy can cause mental health problems in offspring

(Oregon Health & Science University) New research in an animal model suggests a high-fat diet during pregnancy alters the development of the brain and endocrine system of offspring. The new study links an unhealthy diet during pregnancy to mental health disorders such as anxiety and depression in children.

CRI scientists provide insight into genetic basis of neuropsychiatric disorders

(UT Southwestern Medical Center) A study by scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) is providing insight into the genetic basis of neuropsychiatric disorders. In this research, the first mouse model of a mutation in the ARID1B gene was created and then used to show that growth hormone treatments reverse some manifestations of the mutation.

6.5 million pounds (25 billion-pesos) to kick-start Colombian bioeconomy

(Earlham Institute) A four-year investment from RCUK's Global Challenges Research Fund is set to stimulate the bioeconomy by increasing knowledge of Colombia's greatest treasure: its biodiversity

UMass Amherst molecular biologist wins grant to outwit plant fungal diseases

(University of Massachusetts at Amherst) The Fusarium oxysporum fungus causes wilt in over 100 plant species including tomato, cotton, watermelon and banana, costing farmers billions of dollars in losses worldwide each year. The disease is difficult to control. Once the soil is infected, the fungus can remain viable for 30 or 40 years, and at present "there really is no way to control it," Ma says...

Rush hour pollution may be more dangerous than you think

(Duke University) Everyone knows that exposure to pollution during rush hour traffic can be hazardous to your health, but it's even worse than previously thought. In-car measurements of pollutants that cause oxidative stress found exposure levels for drivers to be twice as high as previously believed.

First issue of Structural Heart: The Journal of the Heart Team is now available

(Cardiovascular Research Foundation) The Cardiovascular Research Foundation (CRF) is pleased to announce that the first issue of Structural Heart: The Journal of the Heart Team is now available online.

Rare discovery of 3 new toad species in Nevada's Great Basin

(University of Nevada, Reno) Three new species of toads have been discovered living in Nevada's Great Basin in an expansive survey of the 190,000 square mile ancient lake bottom. 'We've found the toads in small, wet habitats surrounded by high-desert completely cut off from other populations,' Dick Tracy, renowned biology professor at the University of Nevada, Reno, said. 'These are absolutely new...

A genetic variation may increase tuberculosis susceptibility

(Mary Ann Liebert, Inc./Genetic Engineering News) -Researchers have shown that a single nucleotide change in a gene that affects production of hepcidin--a peptide involved in inflammation, immunity, and control of iron levels--is associated with greater susceptibility to extrapulmonary tuberculosis.

Good fighters are bad runners

(University of Utah) For mice and men, a strength in one area of Darwinian fitness may mean a deficiency in another. A look at Olympic athletes shows that a wrestler is built much differently than a marathoner. It's long been supposed that strength in fighting, or protecting territory and resources, comes at the expense of running, or spatial mobility. Now an experiment with house mice provides ev...

In saliva, clues to a 'ghost' species of ancient human

(University at Buffalo) In saliva, scientists have found hints that a 'ghost' species of archaic humans may have contributed genetic material to ancestors of people living in sub-Saharan Africa today. The research adds to a growing body of evidence suggesting that sexual rendezvous between different archaic human species may not have been unusual.

University of Cincinnati creates new model to support workers with disabilities

(University of Cincinnati) The University of Cincinnati's Advancement and Transition Services trained Aramark dining services employees on evidence-based practices used by job coaches to support workers with intellectual and developmental disabilities, or I/DD. The result: the independence levels and social capital of workers with I/DD drastically improved over the course of a semester. The new mo...

Sparkling springs aid quest for underground heat energy sources

(University of Edinburgh) Studies of naturally carbonated mineral water have given scientists insight on how to locate hot water springs -- potential sources of sustainable geothermal energy.

The way of change is important!

(Bentham Science Publishers) However, a new research mind has to emerge in our minds from recent research article 'The Relationship Between Green Building and Regional Economy: A Case Study in Guangdong, China,' published in The Open Civil Engineering Journal.

On the path to vitamin A in rice

(University of Freiburg) Biochemists from the University of Freiburg have elucidated the structure of an enzyme that supplies carotenoid.

Alzheimer's drug may help treat traumatic brain injury

(Wiley) Traumatic brain injury (TBI) is a major cause of disability and death globally, but medications have generally failed to benefit patients.

Depression changes structure of the brain, study suggests

(University of Edinburgh) Changes in the brain's structure that could be the result of depression have been identified in a major scanning study.

How physical exercise prevents dementia

(Goethe University Frankfurt) Numerous studies have shown that physical exercise seems beneficial in the prevention of cognitive impairment and dementia in old age. Now researchers at Goethe University Frankfurt have explored in one of the first studies worldwide how exercise affects brain metabolism.

Pharmacology: Probing the pores in membrane vesicles

(Ludwig-Maximilians-Universität München) Ion channels in the membrane vesicles that mediate intracellular protein transport play a crucial role in cell physiology. A method developed by an Ludwig-Maximilians-Universitaet (LMU) in Munich team now allows them to be studied with greater specificity than ever before.

LSTM awarded £6.4 million to strengthen capacity to control malaria and other diseases

(Liverpool School of Tropical Medicine) Researchers at LSTM have been awarded £6.4 million from the Global Challenges Research Fund to strengthen the global capacity to control vector-borne diseases. Professor Hilary Ranson, Head of LSTM's Department of Vector Biology, will lead a team of experts working with leading research institutes and national disease control programs in three African count...

Offer of $100 boosts rates of colon cancer screenings

(University of Pennsylvania School of Medicine) Offering $100 to patients eligible for a preventive colonoscopy screening more than doubled the rate of screening when compared to a simple emailed request, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

$1.9 million NIH grant to Wayne State to research genetic disease that causes blindness

(Wayne State University - Office of the Vice President for Research) A team of Wayne State University researchers recently received a $1.9 million grant from the National Eye Institute of the National Institutes of Health to better understand leukodystrophies (LD) and genetic Leukoencephalopathies (gLE), rare genetic disorders affecting the white matter -- myelin -- in the central nervous system. ...

Spatial orientation: New model for the origin of grid cells

(Ludwig-Maximilians-Universität München) Ludwig-Maximilians-Universitaet (LMU) in Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals they receive from neurons called place cells.

Socioeconomic factors and severity of coronary artery disease

(Bentham Science Publishers) Historically, from the 1930's to the 1950's, the rate of cardiovascular disease in high-income countries was high. Since the mid-1970's, the rate of cardiovascular disease has declined in high income countries, possibly due to socioeconomic inequalities and better management of risk factors for coronary heart disease among the wealthy.
