Life in the wild harbors the risk of predation, food shortages, harsh climates, and intense competition. Zoo animals, by contrast, are protected from these dangers. Researchers were part of an international team that studied over 50 mammalian species to determine whether the animals live longer in zoos than in the wild.
Over fishing and shark finning may result on more greenhouse gasses and increased climate change, researchers suggest. Their new paper demonstrates the importance of protecting our oceans, and the importance of sharks in marine ecosystems.
The EU area is experiencing challenges in sourcing critical metals. Solutions to this are being sought by the a new project. Researchers are developing technologies for extracting valuable metals from metallurgical waste and low-grade ores, from which recovery is not yet economically viable. The research is serving European industry, which is dependent on the import of critical metals.
Certain proteins in the blood of children can predict incipient type 1 diabetes, even before the first symptoms appear, a team of scientists report.
Scientists have designed a new method to find RNA structures linked to cancer. The formation of quadruplexes by RNA might allow new ways to control gene expression, they report.
Astronomers are investigating the basic principles of the formation of stars. The birth of massive stars is still a mystery to us, because these stars are embedded in an extremely dense medium of gas and dust.
Nanoscale manipulation on the surface of materials could stimulate cells to differentiate into specific tissues, eliminating the use of growth or transcription factors, suggests new research.
Kaikaifilu is a new species of giant sea lizard (mosasaur) discovered in 66-million-year-old rocks of Antarctica. At about 10 meters long, it is the largest known top marine predator from this continent. It lived near the end of the dinosaur age, when Antarctica was a much warmer ecosystem, and fed on filter-feeding marine reptiles.
Many men with prostate cancer obtain second opinions from urologists before starting treatment, but surprisingly, second opinions are not associated with changes in treatment choice or improvements in perceived quality of prostate cancer care. These findings also explore motivations for seeking second opinions, and suggest that second opinions may not reduce overtreatment in prostate cancer.
B12 deficiency during pregnancy may predispose children to metabolic problems such as type-2 diabetes, according to research. These findings could lead to a review of current vitamin B12 requirements for pregnant women, whether through an improved diet or supplements.
Researchers achieved an unexpected eye-popping reduction of ovarian cancer during a successful test of targeted nanohydrogel delivery in vivo in mice. Adding cisplatin eliminated or starkly diminished tumors, report investigators.
A new link between breaking waves and the hazard posed by rip currents has been uncovered by a new study. The research could result in more lives being saved, say authors.
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter intestinal bacteria in a manner that promotes intestinal inflammation and colorectal cancer, according to a new study.
A new comprehensive study of Australian natural hazards paints a picture of increasing heatwaves and extreme bushfires as this century progresses, but with much more uncertainty about the future of storms and rainfall.
A drug that is showing some early promise in efforts to prevent pre-term birth has been successfully tested by a team of investigators.
Researchers have not only built microelectromechanical systems (MEMS) devices the size of insects, but have also created them to move just like real insects.
To better understand why some people adapt well to life at high altitude while others don’t, researchers studied red blood cells derived from representatives of both groups living in the Andes Mountains. The study reveals that high-altitude, low-oxygen dwellers prone to chronic mountain sickness produce massive amounts of red blood cells thanks to overproduction of the enzyme SENP1.
Researchers have identified several new biological markers to measure the progression of the inherited neurodegenerative disorder Huntington’s disease. Their findings could benefit clinical trials that test new treatments for the disease.
Vitamin D deficiency is associated with an increased risk of developing bladder cancer, according to a systematic review of seven studies. Though further clinical studies are needed to confirm the findings, the study adds to a growing body of evidence on the importance of maintaining adequate vitamin D levels.
Ophthalmologist emphasizes care in dim-light driving as time change brings darkness to evening commute
As the end of daylight saving time draws near, ophthalmologists want to focus on a real issue—dim-light driving situations that can endanger drivers and pedestrians.
