A range of information is collated through a simple framework that will help marine scientists to design more accurate experiments that will better help them understand the projected impact of global warming on marine life.
New research reveals rising rates of liver cancer around the world, despite advances aimed at preventing the disease. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
In a recent paper in the open-access journal Neotropical Biology and Conservation, a group of Brazilian scientists from the Federal University of Viçosa (Brazil) published ten different defensive behaviours for the False Coral Snake (Oxyrhopus rhombifer), seven o
Results from a randomised controlled trial involving 300 prostate cancer patients find that a molecular imaging technique is more accurate than conventional medical imaging and recommends the scans be introduced into routine clinical practice.
The world expects some teenagers to become criminals. These "troublemakers" are taken away from everything and everyone they know. The State places them in children's homes, often far from family and friends.
"Care-leavers from children's homes live with more layers of vulnerability. They can be more vulnerable than youth growing up in poor families", says Prof Adrian van Breda. He is a researcher at the Department of Social Work, University of Johannesburg, South Africa.
The American College of Cardiology has released the 2020 Clinical Competencies for Nurse Practitioners and Physician Assistants in Adult Cardiovascular Medicine, identifying the knowledge and skills that are important for nurse practitioners (NPs) and physician assistants (PAs) working in general cardiovascular medicine and cardiovascular medicine subspecialty areas. This is the first competency statement issued for non-physician members of the cardiovascular care team.
A new method to accurately record brain activity at scale has been developed by researchers at the Crick, Stanford University and UCL. The technique could lead to new medical devices to help amputees, people with paralysis or people with neurological conditions such as motor neurone disease.
The research in mice, published in Science Advances, developed an accurate and scalable method to record brain activity across large areas, including on the surface and in deeper regions simultaneously.
Former Tropical Cyclone Herold is now a fading area of low-pressure in the Southern Indian Ocean and NASA's Aqua satellite provided forecasters with a visible image.
Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen has produced a new nanomaterial based on the Egyptian blue pigment, which is ideally suited for applications in imaging using near infrared spectroscopy and microscopy. The results have been published in the journal Nature Communications.
Over the past decade, the idea of photonic computing - where electrons are replaced with light in microelectronic circuits - has emerged as a future technology. This promises low-cost, ultra-high-speed and potentially quantum-enhanced computing, with specific applications in high-efficiency machine learning and neuromorphic computing. While the computing elements and detectors have been developed, the need for nanoscale, high-density and easily-integrated light sources remains unmet.
Teams around the world are working hard to develop active substances against SARS-CoV-2. The structural analysis of functional proteins of the virus is very helpful for this goal. The function of a protein is closely related to its 3D architecture. If this 3D architecture is known, it is possible to identify specific points of attack for active substances.
Stratospheric aerosol geoengineering is the idea that adding a layer of aerosol particles to the upper atmosphere can reduce climate changes caused by greenhouse gases such as carbon dioxide.
A novel serotype 2 oral poliovirus vaccine - and complete removal of the current formulation (OPV2) - is urgently needed, a new statistical modeling study suggests. Its results demonstrate that, despite the withdrawal of OPV2 in 2016, the aftereffects of its administration continue to contribute to the highest number of vaccine-derived poliovirus outbreaks and transmission rates to date.
Stanford researchers have developed a technique that reprograms cells to use synthetic materials, provided by the scientists, to build artificial structures able to carry out functions inside the body.
"We turned cells into chemical engineers of a sort, that use materials we provide to construct functional polymers that change their behaviors in specific ways," said Karl Deisseroth, professor of bioengineering and of psychiatry and behavioral sciences, who co-led the work.
Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital have improved our understanding of how tremor -- the most common movement disorder -- happens, opening the possibility of novel therapies for this condition.
