WEST LAFAYETTE, Ind. - A global forecast of how invasive species could travel and spread in the 21st century shows that areas in most critical need of proactive management strategies are those with high poverty levels, rich biodiversity and low historical levels of invasion.
Invasive species - non-native animals, plants or microbes that spread quickly - can dramatically alter landscapes, ecosystems and human livelihoods, often with harmful consequences.
Analysis in Journal Nature Communications says humanity's impact on terrestrial environment has fallen behind population and economic growth Urbanization and good government contribute to slow-down Environmental impacts are still "frighteningly extensive," scientists warn Three quarters of the planet are significantly altered; 97 percent of species-rich regions are seriously altered Findings come days before kick-off of IUCN World Conservation Congress in Hawaii
Washington, DC - August 23, 2016 - Stopping the explosive spread of Zika virus - which can lead to birth defects in babies born to infected mothers - depends on genetic insights gleaned through new tools and models. Researchers at the National Institutes of Health recently cloned an epidemic strain of the virus, creating a model that can help biologists develop and test strategies for stopping the pandemic.
BROOKLYN, New York -- With the outsourcing of microchip design and fabrication worldwide, a $350 billion business, bad actors along the supply chain have many opportunities to install malicious circuitry in chips. These "Trojan horses" look harmless but can allow attackers to sabotage healthcare devices; public infrastructure; and financial, military, or government electronics.
BUFFALO, N.Y. - Would people living with HIV be willing to self-report on daily substance use and antiretroviral therapy (ART) adherence using a smartphone app?
That was a question researchers from the University at Buffalo set out to answer in a recent study. They were pleased to find that participants not only found the app easy and convenient to use -- they were also willing to provide honest responses.
Kyoto, Japan -- Japan's favorite beverage might be offering more than just a relaxing tea break.
According to new research, green tea could prevent a deadly condition in the body's main artery. A Kyoto University team has found that abdominal aortic aneurysm -- a condition in which the main artery becomes overstretched and bloated -- developed less frequently in rats that drank green tea polyphenol, a major component of green tea.
Without treatment, abdominal aortic aneurysms eventually rupture and lead to death 50% of the time.
The fossil remains of a new tiny species of marsupial lion which prowled the lush rainforests of northern Australia about 18 million years ago have been unearthed in the Riversleigh World Heritage Area of remote north-western Queensland.
The UNSW discovery team has named the new species Microleo attenboroughi for its small size and to honour the famous broadcaster and naturalist Sir David Attenborough, in recognition of his support for the Riversleigh World Heritage Area, which he has described as one of the four most important fossil areas in the world.
Enthesitis, inflammation of tendons where they attach to the bone, is a common medical problem which underlies various forms of inflammatory rheumatism. Although around 1% of the population is affected, the mechanisms driving this type of inflammatory condition is poorly understood. Research by Professor Dirk Elewaut (VIB-UGent/UZ Gent), in collaboration with Professor Geert van Loo (VIB-UGent) at VIB's inflammation research center (IRC), is now changing this. The researchers have demonstrated that macrophages, a particular type of white blood cell, play a key role.
Increased sea temperatures could dramatically enhance and accelerate radiation-induced DNA effects in marine invertebrates, a new study suggests.
Led by Plymouth University, in conjunction with the Centre for Environment, Fisheries and Aquaculture Science (Cefas), the research for the first time explored the impact of rising temperatures coupled with the presence of tritium, an environmentally relevant radionuclide, on marine mussels (Mytilus galloprovincialis).
Certain ingredients in essential oils made from plants such as cloves, anise, fennel and ylang-ylang could serve as a natural treatment of lung and liver conditions caused by air pollution. This is according to Miriana Kfoury of the Unité de Chimie Environnementale et Interactions sur le Vivant, Université du Littoral Côte d'Opale in France and the Lebanese University in Lebanon. She is the lead author of a study in Springer's journal Environmental Chemistry Letters.

A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.
The WHO Fracture Risk Assessment Tool (FRAX®) is a resource developed for the calculation of an individual's 10-year probability of hip fracture and a major osteoporotic fracture based on specific clinical risk factors, with or without bone mineral density (BMD) values.
The Swedish National Board of Health and Welfare recently raised the recommended target blood pressure for patients with diabetes. This may lead to more patients suffering from stroke or heart attack, according to a new study from the Sahlgrenska Academy. The new study is the world's largest on the subject and is based on data from the National Diabetes Register.
In February 2015, the Swedish National Board of Health and Welfare raised the recommended goal for systolic blood pressure (blood pressure when the heart is contracting) in their guidelines for diabetes care.
A study from Emory AIDS researchers shows how the expected disease severity when someone is newly infected by HIV reflects a balance between the virus' invisibility to the host's immune system and its ability to reproduce.
Examining HIV transmission events occurring in 169 heterosexual couples in Zambia, the researchers found that almost a third of potential immune target sites in the virus that established infection were "pre-adapted" to the immune response in the newly-infected partner.
