When people are able to vote they are more likely to pressure leaders to become involved in foreign affairs more aggressively. And so democracies are more likely to militarily intervene in other countries. Since such other countries could be autocracies, dictatorships are far less likely to be involved in international disputes than leaders of republics, suggests a new paper published by the American Journal of Political Science.

A plant's defense systems help each other. When one system fails, another one can - at least in part - take over.
Researchers at the Norwegian University of Science and Technology 's (NTNU) Department of Biology have been collaborating with colleagues from Imperial College London and The Sainsbury Laboratory to discover more about how plants defend themselves. Their results have been published in the 26 June 2018 issue of Science Signaling.
Identifying the danger
Professor Arne Skerra of the Technical University of Munich (TUM) has succeeded for the first time in using gaseous CO2 as a basic material for the production of a chemical mass product in a biotechnical reaction. The product is methionine, which is used as an essential amino acid, particularly in animal feed, on a large scale. This newly developed enzymatic process could replace its current petrochemical production. The results have now been published in the journal Nature Catalysis.
Sophia Antipolis, July 26, 2018: Older, overweight scuba divers are being urged to shed pounds to avoid an underwater heart attack. That's the advice from a large study out today in the European Journal of Preventive Cardiology, a publication of the European Society of Cardiology (ESC).1
It is more likely that you have seen a habu snake in a bottle of local rice liquor Awamori, in Okinawa, than that you've spotted one slithering by the wayside. Even so, habus are very common in the Ryukyu islands of which Okinawa is a part. Okinawa is home to three species of habu; the Okinawan habu (Protobothrops flavoviridis), endemic to the Ryukyu islands, is highly venomous.
University of Manchester and Salford Royal NHS Trust scientists have developed a lamp which could treat chronic ulcers with light.
The Arthritis Research UK funded trial led by Dr Michael Hughes tested the therapy - which combines infrared, red and ultraviolet light - on finger ulcers caused by a condition called systemic sclerosis, where the immune system attacks the body's fingers and toes.
Alexandria, Va., USA - At the 96th General Session of the International Association for Dental Research (IADR), held in conjunction with the IADR Pan European Regional (PER) Congress, Paula Moynihan, Newcastle University, England, gave an oral presentation titled "Relationship Between Amount and Frequency of Sugars Intake by Children." The IADR/PER General Session & Exhibition is in London, England at the ExCeL London Convention Center from July 25-28, 2018.
The disparity between the number of sexual partners reported by men and women can largely be explained by a tendency among men to report extreme numbers of partners, and to estimate rather than count their lifetime total, a new study in The Journal of Sex Research finds.
Together with gender differences in attitudes towards casual sex, this explains roughly two-thirds of the notorious 'gender gap' found in many sex surveys.
TORONTO, July 25, 2018 - Engaging patients in the redesign of health care services can lead to reduced hospital admissions and more efficient and effective health care, a study led by a St. Michael's Hospital researcher suggests.
In their study, Engaging Patients to Improve Quality of Care: A Systematic Review, published today in Implementation Science, lead authors Dr. Yvonne Bombard and Dr. G. Ross Baker concluded that active engagement of patients can inform education, tools, planning and policy, and enhance health care service delivery and governance.
New research gives insights into how the design of clinical trials can improve to address the "critically low" research pipeline and improve the chances of finding effective dementia therapies.
Maunakea, Hawaii - A team of astronomers has discovered a new way to unlock the mysteries of how the first galaxies formed and evolved.
In a study published today in Astrophysical Journal Letters, lead author Dawn Erb of the University of Wisconsin-Milwaukee and her team - for the very first time - used new capabilities at W. M. Keck Observatory on Maunakea, Hawaii to examine Q2343-BX418, a small, young galaxy located about 10 billion light years away from Earth.
Scientists have discovered that some treatments for cancer and sickle cell disease can destroy the germ cells that go on to develop into sperm in the testes of young boys. In some pre-pubescent boys, the treatment for sickle cell disease results in complete destruction of all their germ cells, which are called spermatogonia.
Researchers from King's College London have assessed just how much sun protection people actually receive, based on typical use. It is well known that people don't receive the full ultraviolet radiation blocking benefit of sunscreen, because they are applying it more thinly than manufacturers recommend. The findings are published in journal Acta Dermato-Venereology.
Study finds engineered rice lines with low stomatal density used just 60 per cent of the normal amount of water and were able to survive drought and high temperatures for longer than unaltered plants.
Almost half of the global rice crop derives from rain-fed agricultural systems where drought and high temperatures are predicted to become more frequent and damaging under climate change.
Rice cultivation is particularly water intensive - using an estimated 2,500 litres of water per kilogram.
CORVALLIS, Ore. - A continuous wall on the border between the United States and Mexico would harm a multitude of animal species by fragmenting their geographic ranges, Oregon State University distinguished professor of ecology William Ripple has concluded, supported by thousands of other scientists around the globe.
Ripple is one of 16 co-authors from the U.S. and Mexico, including four members of the National Academy of Sciences, of a paper published today in BioScience that outlines the wall's impacts on biodiversity.
