Diving 200 feet under the ocean surface to conduct scientific research can lead to some interesting places. For University of Texas at Austin Professor Bayani Cardenas, it placed him in the middle of a champagne-like environment of bubbling carbon dioxide with off-the-chart readings of the greenhouse gas.
About 80 percent of water systems across the country use a disinfectant in drinking water that can lead to undesirable byproducts, including chloroform. There is an alternative, but many cities have been afraid to use it.
That's because in 2000, when the water authority in Washington, D.C., switched from free chlorine to chloramine, the nation watched as levels of lead in drinking water immediately shot up. They stayed up for four years while scientists determined the problem and implemented a solution.
A team of international researchers, which includes a Saint Louis University Madrid anthropologist, dug deep to find some of the oldest African DNA on record, in a new study published in Nature.
Australian research collaboration makes first detection of 'ghost particles' from Bose-Einstein condensates made of light and matter.
The ANU/Monash University collaboration study:
Observed 'quantum depletion' for the first time in a non-equilibrium condensate
Discovered that 'light-like' condensates don't behave as we would expect
Observed 'ghost' excitations arising from quantum depletion for the first time.
QUANTUM DEPLETION OBSERVED FOR THE FIRST TIME
Bose-condensed quantum fluids are not forever.
Among the Marvel characters, Spider-man has been the most popular character for the longest time of its history. The most attractive superpower of the Spider-man is that he shoots sticky spider webs to cling to walls or fly between buildings. Would his spider web be powerful in underwater, too? The answer is no. Because spider webs are dissolved in water and show no longer strong adhesion. However, mussels are capable of strong underwater adhesion. It is not even affected by heavy waves or storms. When a mussel is removed from a rock by force, surface of rock is also teared.
CAMBRIDGE, MA -- After a patient has a heart attack or stroke, doctors often use risk models to help guide their treatment. These models can calculate a patient's risk of dying based on factors such as the patient's age, symptoms, and other characteristics.
While these models are useful in most cases, they do not make accurate predictions for many patients, which can lead doctors to choose ineffective or unnecessarily risky treatments for some patients.
Olivier Feron, a researcher at the University of Louvain (UCLouvain) Institute of Experimental and Clinical Research, seeks to understand how metastases form from a tumour. He already demonstrated that the most aggressive cancer cells use significant amounts of lipids as energy sources. Now Prof. Feron has discovered that cancer cells store lipids in small intracellular vesicles called 'lipid droplets'. Cancer cells loaded with lipids are more invasive and therefore more likely to form metastases. Prof.
During the early summer, corals simultaneously release tiny balls composed of sperms and eggs, known as bundles, that float to the ocean surface. Here the bundles open, allowing the sperm to fertilize the eggs where they eventually settle on the seafloor and become new coral on the reef.
Researchers at the University of Sydney have used human stem cells to make pain-killing neurons that provide lasting relief in mice, without side effects, in a single treatment.
The next step is to perform extensive safety tests in rodents and pigs, and then move to human patients suffering chronic pain within the next five years.
If the tests are successful in humans, it could be a major breakthrough in the development of new non-opioid, non-addictive pain management strategies for patients, the researchers said.
Loggerhead turtles feed in the same places year after year - meaning key locations should be protected, researchers say.
University of Exeter scientists used satellite tracking and "stable isotope ratios" - a chemical signature also used by forensic scientists - to track female loggerheads from two rookeries (nesting beaches) in the Mediterranean.
The study identified three main feeding areas - the Adriatic region, the Tunisian Plateau and the eastern Mediterranean.
Following a premature birth it is important that the parents and the infant quickly establish a good relationship. Researchers at Linköping University have studied the relationship between mothers and infants who have continuous skin-to-skin contact during the entire period from birth to discharge from the hospital. The results show that continuous skin-to-skin contact does not lead to better interaction between the mother and the infant. The study is published in the scientific journal Advances in Neonatal Care.
In the current climate change scenario, an international team led by researchers from Pablo de Olavide University (UPO) and the Autonomous University of Madrid (UAM) has carried out research that suggests global warming could have a negative impact on the processes that generate biodiversity. This is one of the conclusions of a study, recently published in the international scientific Journal of Systematics and Evolution, that focuses on the causes of the evolutionary success of Carex, one of the worlds' three largest genera of flowering plants.
There is a difference between seeing a patient with a catalogue of two or more serious chronic diseases and a healthy patient who just needs a prescription to treat a case of cystitis.
Foxtail millet is an annual grass grown widely as a cereal crop in parts of India, China and Southeast Asia. Milling the grain removes the hard outer layer, or bran, from the rest of the seed. Now, researchers have identified a protein in this bran that can help stave off atherosclerosis in mice genetically prone to the disease. They report their results in ACS' Journal of Agricultural and Food Chemistry.
Ahead of the European Commission's official launch of 'Europe's Beating Cancer Plan', The Health Policy Partnership and an expert-led steering committee met at the European Parliament in Brussels today to launch a new report, Radioligand therapy: realising the potential of targeted cancer care.
