MADISON, Wis. – Marital stress may make people more vulnerable to depression, according to a recent study by University of Wisconsin-Madison researchers and their colleagues. The long-term study, published in the April 2014 Journal of Psychophysiology, shows that people who experience chronic marital stress are less able to savor positive experiences, a hallmark of depression. They are also more likely to report other depressive symptoms. The findings are important, says study leader Richard Davidson, UW-Madison William James and Vilas Professor of Psychology and Psychiatry, ...

April is in the middle of the dry season, which runs from January through May in this region, and naturally coincides with fire season. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. Fire helps enhance crops and grasses for pasture. Some of the fires in this image may be wildfires, with natural (lightning) or accidental (human) sources. As the dry season progresses, the number of fires tend to grow, as does the blanket of smoke which settles over the land, and although the fire may help the farmers get their lands ready ...

OTTAWA, April 24, 2014 - A new study from researchers at the University of Ottawa Heart Institute (UOHI), published today in Cell Reports, sheds light on a mysterious gene that likely influences cardiovascular health. After five years, UOHI researchers now know how one genetic variant works and suspect that it contributes to the development of heart disease through processes that promote chronic inflammation and cell division. Researchers at the Ruddy Canadian Cardiovascular Genetics Centre had initially identified a variant in a gene called SPG7 as a potential contributor ...

TORONTO, April 25, 2014—Almost half of all homeless men who took part in a study by St. Michael's Hospital had suffered at least one traumatic brain injury in their life and 87 per cent of those injuries occurred before the men lost their homes. While assaults were a major cause of those traumatic brain injuries, or TBIs, (60 per cent) many were caused by potentially non-violent mechanisms such as sports and recreation (44 per cent) and motor vehicle collisions and falls (42 per cent). The study, led by Dr. Jane Topolovec-Vranic, a clinical researcher in the hospital's ...

April 24, 2014 CHAPEL HILL, N.C. – The evidence for what causes aging has typically been limited to the study of a single organism's lifespan; our cells divide many times throughout our lives and eventually cause organs and our bodies to age and break down. But new research from the UNC School of Medicine suggests that how we age might depend on cellular interactions that we inherit from ancestors throughout many generations. By studying the reproductive cells of nematodes – tiny worms found in soil and compost bins – Shawn Ahmed, PhD, an associate professor of genetics, ...

JUPITER, FL – April 25, 2014 – Scientists have known that abnormal brain growth is associated with autism spectrum disorder. However, the relationship between the two has not been well understood. Now, scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown that mutations in a specific gene that is disrupted in some individuals with autism results in too much growth throughout the brain, and yet surprisingly specific problems in social interactions, at least in mouse models that mimic this risk factor in humans. "What was striking is ...

A research team lead by Academy Professor Kari Rissanen at the University of Jyväskylä has discovered a new water-soluble fluorescent detection system that is extremely sensitive to pyrophosphate (PPi). Pyrophosphate has a key role in energy transduction, DNA replication and other metabolic processes that are dysregulated in cancer cells. The discovery might lead to the development of a method for early detection of cancer cells. The team developed a simple metal complex which shows an intense orange fluorescent color in the presence of very low concentration of pyrophosphate ...

A paper summarising some of the findings will be published in the journal Science today, with more specific and in depth analyses of various aspects of tsetse biology being published as a collection ...

Researchers at Aarhus University, Denmark, have drawn up the most detailed 'image of the enemy' to date of one of the body's most important players in the development of Parkinson's disease. This provides much greater understanding of the battle taking place when the disease occurs – knowledge that is necessary if we are to understand and treat Parkinsonism. However, it also raises an existential question because part of the conclusion is that we do not live forever! Parkinson's disease is one of the most common neurological disorders, with about 7000 people suffering ...

Drexel's Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish. Using a mixture of cervical cancer cells and a hydrogel substance that resembles an ointment balm, Sun can print out a tumor model that can be used for studying their growth and response to treatment. This living model will give cancer researchers a better look at how tumors behave and a more accurate measure of how they respond to treatment. "This is the first time to report ...

A new study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass. Researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone. It also shows a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle building. ...

A new report quantifies for the first time how much our food choices affect pollutant nitrogen emissions, climate change and land-use across Europe. The executive summary of the European Nitrogen Assessment Special Report on Nitrogen and Food, 'Nitrogen on the Table', was released today (Friday 25 April 2014). The Special report provides an assessment of what would happen if Europe were to decrease its consumption of meat and dairy products. It shows how much cutting down on meat and dairy in our diets would reduce nitrogen air and water pollution, and greenhouse gas ...

ANN ARBOR, Mich. — There's a civil war going on inside every one of the 37 trillion cells in your body. Now, University of Michigan scientists have uncovered how your cells keep this war from causing too much collateral damage. On one side of the battle: your "regular" DNA, which provides the day-to-day instructions for life. On the other side: tiny bits of rogue DNA that hide like spies between genes in your own DNA. From time to time, these rogue bits of DNA spin off a copy of themselves and "jump" to another DNA location – often causing harmful mutations when they ...

The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits. The geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time. Evidence of liquid water When sediment on a slope becomes saturated with water, the mixture may become too heavy to remain in place, leading to a flow of debris and water as a single-phase unit. This is called a debris flow. Debris flows on Earth often cause significant material destruction and even human ...

Scientists at the University of Liverpool have been part of a ten-year project which has successfully sequenced the genetic code of the tsetse fly – making major advances in disease control possible. Tsetse flies are unique to Africa and can infect people bitten by them with sleeping sickness, a disease which damages the nervous system and is fatal if untreated. This kills over 250,000 people each year. Traditional methods of control such as releasing sterile males, trapping and pesticide spraying are expensive and difficult to implement. Sleeping sickness can also ...

The optic radiation is a dense fiber tract that emerges from the lateral geniculate nucleus and continues to the occipital visual cortex. Especially, the optic radiation is an important fiber structure that conveys visual information from the lateral geniculate nucleus to the primary visual cortex in the occipital lobe. Current studies have focused on the anatomical characteristics of optic radiation fiber tracts in individual brains and on comparisons of the anatomical characteristics of the optic radiation fiber tracts between patient and control groups. Therefore, no ...

Washington, D.C.— Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New work from Carnegie's Katharine Ricke and Ken Caldeira focuses on the intersection between personal and global impacts. They find that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades. Their findings ...

HEIDELBERG, 25 April 2014 – Researchers from the University of Cambridge have published details about how the first organisms on Earth could have become metabolically active. The results, which are reported in the journal Molecular Systems Biology, permit scientists to speculate how primitive cells learned to synthesize their organic components – the molecules that form RNA, lipids and amino acids. The findings also suggest an order for the sequence of events that led to the origin of life. A reconstruction of Earth's earliest ocean in the laboratory revealed the spontaneous ...

The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin of life. In new research funded by the Wellcome Trust, researchers at the University of Cambridge reconstructed the chemical make-up of the earth's earliest ocean in the laboratory. The team found the spontaneous occurrence of reaction sequences which in modern organisms enable the formation of molecules essential for the synthesis of metabolites such as amino acids, ...
