What is the best way to monitor a brain tumor? This question is at the heart of a new Position Statement published in open-access journal Frontiers in Oncology. The article is the work of a large collaboration of UK experts and stakeholders who met to discuss the value of routinely imaging brain tumor patients to assess their tumor treatment response, which is known as "interval imaging".
DALLAS, Feb. 9, 2021 -- Participants in a two-year, lifestyle intervention/weight-loss program provided through health coaches at their primary care center were able to lower their blood sugar and improve their cholesterol levels, according to new research published today in the American Heart Association's flagship journal Circulation Journal.
DALLAS, Feb. 9, 2021 -- Dietary information from three large, well-known heart disease studies suggests drinking one or more cups of caffeinated coffee may reduce heart failure risk, according to research published today in Circulation: Heart Failure, an American Heart Association journal.
In 2017, a widely cited study used statistical tools to model how likely the world is to meet the Paris Agreement global temperature targets. The analysis found that on current trends, the planet had only a 5% chance of staying below 2 degrees Celsius warming this century -- the international climate treaty's supposed goal.
The term plankton describes usually very small organisms that drift with the currents in the seas and oceans. Despite their small size, they play an important role for our planet due to their immense quantity. Photosynthesizing plankton, known as phytoplankton, for example, produce half of the oxygen in the atmosphere while binding huge amounts of carbon dioxide (CO2). Since the Southern Ocean around Antarctica is very rich in nutrients, phytoplankton can thrive there. It is therefore a key region for controlling atmospheric CO2 concentrations.
Exposure to radiation can wreak indiscriminate havoc on cells, tissues, and organs. Curiously, however, some tissues are more vulnerable to radiation damage than others.
Scientists have known these differences involve the protein p53, a well-studied tumor-suppressor protein that initiates a cell's auto-destruct programs. Yet, levels of this sentinel protein are often similar in tissues with vastly different sensitivities to radiation, posing the question: How is p53 involved?
Under increasing global warming, tropical fish are escaping warmer seas by extending their habitat ranges towards more temperate waters.
But a new study from the University of Adelaide, published in Nature Climate Change, shows that the ocean acidification predicted under continuing high CO2 emissions may make cooler, temperate waters less welcoming.
Which bananas end up in your shopping basket-- the uniformly yellow ones or those with brown spots?
If you are like most people, you skip the spotted ones and select those that are perfectly yellow. This is because emotions play an an oversized role in our shopping decisions, according to a new study by Danish and Swedish researchers.
A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has developed a new material, that when electricity is applied to it, can flex and bend forty times more than its competitors, opening the way to better micro machines.
Conversely, when it is bent, it generates electricity very effectively and could be used for better "energy harvesting" - potentially recharging batteries in gadgets just from everyday movements.

An international team of scientists has invented the equivalent of body armour for extremely fragile quantum systems, which will make them robust enough to be used as the basis for a new generation of low-energy electronics.
The scientists applied the armour by gently squashing droplets of liquid metal gallium onto the materials, coating them with gallium oxide.
Osaka, Japan - Bone morphogenetic protein (BMP) has a strong osteogenic (bone forming) ability. BMP has already been clinically applied to spinal fusion and non-union fractures. However, dose-dependent side effects related to BMP use, such as inflammatory reactions at the administration site, prevent widespread use.
Lithium metal batteries could double the amount of energy held by lithium-ion batteries, if only their anodes didn't break down into small pieces when they were used.
Now, researchers led by Prof. CUI Guanglei from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have identified what causes lithium metal batteries (LMBs) to "self-destruct" and proposed a way to prevent it. The findings were published in Angewandte Chemie on Jan. 19.
Solar energy is one of the most abundant renewable energy sources, and effective solar technologies have great potential to alleviate the grand challenges of rising global energy demands, while reducing associated emissions. Solar energy is capable of satisfying the electrical and thermal-energy needs of diverse end-users by means of photovoltaic (PV) and solar thermal (ST) technologies, respectively.
For decades, the speed of our computers has been growing at a steady pace. The processor of the first IBM PC released 40 years ago, operated at a rate of roughly 5 million clock cycles per second (4.77 MHz). Today, the processors in our personal computers run around 1000 times faster.
However, with current technology, they're not likely to get any faster than that.
