Amazon river dolphins are showing alarming levels of contamination mainly because of illegal panning for gold, conservationists say.
Astronomers dedicated to the search for extraterrestrial intelligence (SETI) have announced a new collaboration with scientists working on a NASA telescope.
While particle accelerators may be on the cutting edge of science, the building and preparation of some particle accelerator components has long been more of an art form, dependent on recipes born of trial and error. Now, Ari Deibert Palczewski hopes to change that. A staff scientist at the Department of Energy's Thomas Jefferson National Accelerator Facility, Palczewski has been awarded a DOE...
NASA-NOAA's Suomi NPP satellite and NASA's Aqua satellite both passed over the Northwestern Pacific Ocean and both used infrared light to obtain temperature data and shape information on Typhoon Bualoi.
The global average temperature has increased 1.4 degrees Fahrenheit over the last 100 years. In contrast, the Corn Belt of the U.S., one of the most agriculturally productive regions of the world, has experienced a decrease in temperatures in the summer during the growing season. Known as the "U.S. warming hole," this anomalous cooling phenomenon, which occurred in tandem with increasing rainfall,...
Deformed Wing Virus (DWV), one of the leading causes of honey bee colony losses, is much more genetically diverse in the United States than previously thought, according to a study published by Agricultural Research Service (ARS) scientists in PLoS Biology.
Laryngeal paralysis is a serious and sometimes deadly disease in some dog breeds that prevents proper opening of the larynx for breathing. In a new study published 24th October in PLOS Genetics, a team of German specialists in canine head and neck surgery and geneticists from the University of Bern identify a mutation responsible for laryngeal paralysis in Miniature Bull Terriers, enabling the...
In any single location, there are typically more earthworms and more earthworm species found in temperate regions than in the tropics. Global climate change could lead to significant shifts in earthworm communities worldwide, threatening the many functions they provide. These are the two main results of a new study published in Science. The research was led by scientists from the German Centre for...
The building blocks of rationally designed chemicals are simple elements: carbon, hydrogen, oxygen and so on. These elements can be combined in myriad ways to accomplish a variety of chemicals with different characteristics. Even the same chemical can be treated differently—with pressure or heat, for example—to show drastically different properties. A simpler version is to think of how water...
The last 2.6 million years are characterized by glacial cycles, a regular alternation of cold and warm periods. It is widely accepted that changes in the concentrations of carbon dioxide and other greenhouse gases in the atmosphere were largely responsible for these natural fluctuations of cold and warm periods. What exactly triggers the increase in carbon dioxide concentrations that causes the...
A technology that has enabled ever-faster delivery of voice and data over the Internet and other telecommunications platforms could play a front-and-center role in NASA's quest to develop a super-small instrument for gathering unprecedented details about extraterrestrial planets, moons, comets, and asteroids.
Houston Methodist researchers are studying Italian sports car maker Automobili Lamborghini's carbon fiber materials in space.
Typical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends...
Of the total commercial tuna catch worldwide, 81% came from stocks at "healthy" levels of abundance, according to the October 2019 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 15% of the total tuna catch was from overfished stocks, and 4% was from stocks at an intermediate level of abundance.
In many ways, our phones and smartwatches have become extensions of the human body, allowing us to conquer more ground than we ever could before.
Startups and entrepreneurs should spend the effort and money to obtain trademarks, because trademarks help them succeed in both product and financial markets, researchers say.
Communities in high income countries around the world continue to receive record-setting numbers of newcomers fleeing armed conflict. Although education is known to be highly important for refugee and migrant children, relatively little is known about the diversity of associated school-based programs and their likely value in supporting the mental health and psychosocial well-being of the children...
People tend to pay more attention to how much food they are eating than to how rich their diet is in essential micronutrients like iron. However, if we do not get enough iron, we can become anemic, which leaves us sluggish and can impair growth and development. In the same way, biologists do not usually consider insufficient iron supply as being an important factor for the nutrition of wild...
Current super-resolution microscopes or microarray laser scanning technologies are known for their high sensitivities and very good resolutions. However, they implement high light power to study samples, samples that can be light sensitive and thus become damaged or perturbed when illuminated by these devices.
The study, "Intensification of dairy production can increase the GHG mitigation potential of the land use sector in East Africa," modelled the impact on greenhouse gas emissions and efficiency of three scenarios for feeding nutrient-rich diets to dairy cows in Kenya.
Together with a Ukrainian colleague, Senckenberg researchers examined the 120-year-old specimen of a "Crimean lizard." Until now, these animals had been considered a species of green lizard restricted to the Crimean Peninsula. Based on the complete mitochondrial genome, the team was able to show that these reptiles actually represent a species introduced from Italy. The results emphasize the...
People are less likely to support an organization after an ethical failure if the business is led by a woman, according to a study published by the American Psychological Association. However, organizations led by women endure less negative backlash for competence failures than those headed by men.
Australia has at least seven Leptospermum species that produce honey with exceptionally high levels of antibacterial activity, providing the scientific basis to facilitate the entry of Australian honey producers into premium medicinal markets.
A fast-moving wildfire roared through California wine country early Thursday, as authorities warned of the imminent danger of more fires across much of the Golden State.
