Sepsis causes 11 million deaths annually so preventing that requires prompt recognition, source control, antibiotics, fluids and vasopressors.Sometimes adjunctive therapies such as orticosteroids help but the science is inconclusive. A recent study was designed to evaluate the role of corticosteroids in the management of patients with septic shock and the contradictory effects on mortality as recorded in past research and treatment.

In recent geological history, 90,000 of every 100,000 years have been ice ages. It's been 12,000 years since the last one so we may be due.Or not. Climate science has a few rules but a lot of exceptions and 700,000 years ago a big exception occurred. At that time the planet experienced a “warm ice age” and it permanently changed the climate cycles on Earth. Though it became warmer and with more rain, the polar glaciers also expanded. Geological data in combination with computer simulations published in Nature Communications hopes to lend insight into this paradox.

Screening is underway to find a patient for the world's first bladder transplant in humans. 

If a vaccine requires cold storage for shipping, many areas where infrastructure doesn't hold up are unable to receive them. A possible solution to this problem is a mobile vaccine printer that could produce hundreds of vaccine doses in a day.The printer produces patches with hundreds of microneedles containing the vaccine. The patches can be attached to the skin, allowing the vaccine to dissolve without the need for a traditional injection. Once printed, the vaccine patches can be stored for months at room temperature.In their paper, the scientists used the printer to produce thermostable Covid-19 RNA vaccines that could induce a comparable immune response to that generated by injected RNA vaccines, in mice.

New results show that the number of reported cancer cases in the National Cancer Database during the COVID-19 pandemic declined by 14.4 percen, which means over 200,000 cancer cases were not diagnosed and/or treated.The reasons were unclear, perhaps concern about catching COVID-19 or being symptomatic but not wanting to go to the doctor because of media claims about those unable to get care for SARS-CoV-2. The results are more obvious; a lot of people are at greater risk. 

New research shows that dairy products have made life easier for thousands of years. Even in places that are a challenge for anyone, like the Tibetan Plateau - the “roof of the world.”Genetic engineering due to natural selection at several genomic loci certainly made early Tibetans better able to survive high elevations, but those did nothing for calorie requirements. A new study finds that dairy made it possible. Ancient proteins from the dental calculus of 40 human individuals from 15 sites across the interior plateau show that dairying was introduced onto the hinterland plateau by at least 3,500 years ago.

Bud Light may create a marketing campaign to try and increase its brand but when it comes to pricing, experimentation isn't needed. If you want the most sales, target people who shop prices.It is certainly true that if you have a product during a fad wave, you can charge more. Or, if supplies of a product are scarce, prices will be higher. Yet limited supply means limited revenue. The big money is instead in those who are price shoppers. 

To make solar power viable, there need to be gigantic installations in remote locations. Then there need to be new power lines equivalent to every paved road in America. Then the grid needs to be modernized with battery storage.None of that is happening any time soon but what may spur at least grid improvements is the reliance on natural gas. Though alternative energy gets mandates and subsidies conventional fuel supplies 80 percent of American energy, but natural gas needs energy to get from place to place. While most of that is still, fittingly, supplied by natural gas, in places where it is supplied by electricity, or even less reliable solar electricity, pipelines are far more subject to outages.

In what they are calling the first study to systematically identify aggressive driving behaviors, a team believe they have measured the changes in driving that occur in an aggressive state. Obviously non-professional aggressive drivers drive faster and make more mistakes than non-aggressive drivers, they put other road users at risk. They also pose a challenge to engineers working on self-driving car technology. UK officials claim that 80 percent of UK road deaths are “predominantly caused by dangerous and reckless drivers.”

Natural events like solar cycles, wildfires, and volcanoes have created dramatic shifts in climate throughout history. Sometimes they even have cultural impact, such as the 'year without a summer' in Europe due to a volcano on the other side of the world, which helped inspire Mary Shelley's "Frankenstein."Less understood have been underwater events. A new analysis of bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, which will mean more accurate climate simulations in the future. 

Using data on the structure of galaxy clusters, a recent study made detailed measurements of X-ray emission from galaxy clusters, which revealed the distribution of matter within them. In turn, the data helped the scientists test the prevailing hypothesis of the structure and evolution of the universe, known as Lambda-CDM.

Behavioral data often reveal differences that don't show up on surveys, where answers are free and often aspirational. Data show, for example, that men donate more than women while people who support charities more also have more conservative political stances. The rational is they choose the organizations they want to help, the ones doing work they like. Yet if you get a coffee paid for by the person in front of you at Starbucks, it is likely someone on the left. Charity and generosity are often distinct. A new survey isn't actual behavior but it does lend to the belief that left wing people feel like they are more altruistic.
