Government subsidies for renewable energy rebounded strongly last year, registering a solid 17% increase after two years of declines. Major expansion of solar installations in China and Japan and government=backed investments in offshore wind projects in Europe helped propel green energy spending to $270 billion.
The 2010 eruption of the Icelandic volcano Eyjafjallajökull grounded thousands of air flights and spread ash over much of western Europe, yet it was puny compared to the eruption 200 years ago of Tambora, a volcano that probably killed more than 60,000 people in what is now Indonesia and turned summer into winter over much of the Northern Hemisphere.
Saurichthys is a predatory fish characterized by a long thin body and a sharply pointed snout with numerous teeth. This distinctive ray-finned fish lived in marine and freshwater environments all over the world 252-201 million years ago during the Triassic period.
Triple-negative breast cancers are around 15% of all breast cancers and they lack any of the three receptors (oestrogen, progesterone or HER2) that would make them responsive to targeted drugs.
Triple-negative breast cancer patients have a higher risk of disease recurrence and shorter survival than those with other breast cancers and tend to fall into two categories: those that succumb to their disease within 3-5 years, regardless of treatment; and those that remain disease free for longer than the average non-triple-negative breast cancer patient (at least 8 years post-diagnosis). Survival prospects tend to be either very good or very bad because triple-negative breast cancers are two distinct diseases that likely originate from different cell types.
Up to 1 billion people globally have insufficient or deficient vitamin D levels even though many western nations fortify milk with it. The reason is lack of sun exposure in some places but with a culture war on both sunshine and diet low vitamin D levels have become more common, even for elite college athletes, according to a new study.
But don't be duped into buying supplements, you can get it from your diet. Just eat more fish.
The work found that more than one-third of Division I college athletes may have low levels of vitamin D, which is critical in helping the body to absorb calcium needed to maintain bone mass, and to minimize musculoskeletal pain and injury risk.
Australia’s CSIRO has come up with some pretty amazing inventions over the past 86 years of research, from polymer banknotes to insect repellent and the world-changing Wi-Fi. But we can also lay claim to something a little more esoteric – we actually invented a whole new word.-->
Cholesterol-lowering statins have transformed the treatment of heart disease. But while the decision to use the drugs in patients with a history of heart attacks and strokes is mostly clear-cut, that choice can be a far trickier proposition for the tens of millions of Americans with high cholesterol but no overt disease.
Now a report from preventive cardiologists at Johns Hopkins and elsewhere offers a set of useful tips for physicians to help their patients make the right call.
The report, published March 30 in the Journal of the American College of Cardiology, combines the experts' collective clinical wisdom with previously published research on the benefits and potential downsides to long-term statin use.
The UN Intergovernmental Panel on Climate Change (IPCC) is a group of climate change experts representatively selected from regions around the world that periodically releases Assessment Reports in order to inform policymakers and the public about the latest evidence for climate change. The publication of each report is a key event in the debate about climate change, but their reception and coverage in the media has varied widely.
A new paper has for the first time analyzed how Twitter, TV and newspapers reported the IPCC's climate evidence. Understanding how media coverage varies is important because people's knowledge and opinions on climate change are influenced by how the media reports on the issue.
Natural wetlands usually emit methane and sequester carbon dioxide. Anthropogenic interventions, in particular the conversion of wetlands for agriculture, result in a significant increase in CO2 emissions, which overcompensate potential decreases in methane emission. A large international research team now calculated that the conversion of arctic and boreal wetlands into agricultural land would result in an additional cumulative radiative forcing of about 0,1 MilliJoule (mJ) per square meter for the next 100 years.
