Efforts to create synthetic replacements for palm oil are still likely to take several years, so immediate attention should be focused on making the existing production process more sustainable, researchers at the University of Bath's Centre for Integrated Bioprocessing Research (CIBR) and Centre for Sustainable Circular Technologies (CSCT) have found.
A new study in Finland has revealed that inherited malignant ventricular arrhythmia is fairly common among Finnish Leonbergers under three years of age. At its worst, such arrhythmia can result in the dog's sudden death.
Arrhythmia and sudden death in Leonbergers have been a subject of research coordinated by Professor Hannes Lohi since 2016 at the Faculty of Veterinary Medicine, University of Helsinki, the University's Veterinary Teaching Hospital and the Finnish Food Authority.
Meltwater pulses (MWPs) known as abrupt sea-level rise due to injection of melt water are of particular interests to scientists to investigate the interactions between climatic, oceanic and glacial systems. Eustatic sea-level rise will inevitably affect cities especially those on coastal plains of low elevation like Hong Kong. A recent study published in Quaternary Science Reviews presented evidence of abrupt sea level change between 11,300-11,000 years ago in the Arctic Ocean.
An analysis of publicly available data on infections from the new coronavirus, SARS-CoV-2, that causes the respiratory illness COVID-19 yielded an estimate of 5.1 days for the median disease incubation period, according to a new study led by researchers at Johns Hopkins Bloomberg School of Public Health. This median time from exposure to onset of symptoms suggests that the 14-day quarantine period used by the U.S. Centers for Disease Control and Prevention for individuals with likely exposure to the coronavirus is reasonable.
AURORA, Colo. (March 9, 2020) - Knowing the amount of opioids taken following cesarean section surgery and before discharge can inform individualized prescriptions and cut down on unnecessary, leftover pills that could be used for non-medical purposes, according to a new study from the University of Colorado Anschutz Medical Campus.
INFORMS journal Manufacturing & Service Operations Management New Study Key Takeaways:
Continuity of care leads to substantial improvements in patient outcomes, up to a point, more so for sicker patients.
Continuity of care leads to fewer inpatient visits, shorter lengths of stay on those visits, and lower readmission rates.
Variety in care becomes important at a certain stage because outcomes tend to grow worse at the very highest levels of continuity of care.
Some species of fish, notably parrotfish and wrasses living on coral reefs, change their biological sex as they age, beginning life as females and later becoming functionally male. New work from the University of California, Davis, shows that this sequential hermaphroditism evolves when bigger males gain an advantage in reproductive success -- for example by defending a permanent mating territory.
Standing desks are so passé. It's time for squatting desks.
A USC-led study shows that squatting and kneeling may be important resting positions in human evolution -- and even for modern human health.
Sitting for hours a day is linked to some health risks, including cardiovascular disease, likely because it involves low muscle activity and low muscle metabolism. However, these risks seem paradoxical. For humans, evolutionary pressures favor conserving energy. Spending a lot of time sitting would seem to accomplish that goal. So, why should sitting be so harmful?
Feeding and fasting cycles exert control over metabolism and energy utilization of organisms. Any aberration is known to cause metabolic diseases, liver dysfunctions and accelerated aging. Expression and activity of the anti-aging factor SIRT1 has long been known to be beneficial in mitigating diseases such as diabetes, cardiovascular dysfunctions, neurodegeneration, cancer and aging. Global efforts are underway to both uncover molecular mechanisms that affect feed-fast cycles and also to regulate the activity of the longevity factor SIRT1.
Misleading portrayals of the safety of tobacco use are widespread on YouTube, where the viewership of popular pro-tobacco videos has soared over the past half-dozen years, according to research by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.
In an article published today in the Harvard Kennedy School Misinformation Review, APPC researchers found that from 2013 to 2019, different kinds of popular tobacco-themed YouTube videos saw "dramatic increases in views per day, especially for tutorials about vaping products."
Oxygenic photosynthesis is the conversion of sunlight into chemical energy that underpins the survival of virtually all complex life forms. The energy conversion is driven by a photosynthetic apparatus that captures light photons in the bioenergetic membranes of cyanobacteria, algae and plants. Photosystem I is a central component of this process.
BOSTON/NEW HAVEN - A newly approved drug for HIV pre-exposure prophylaxis (PrEP) is unlikely to confer any discernible health benefit over generic alternatives and may undermine efforts to expand access to HIV prevention for the nation's most vulnerable populations, according to a new study appearing today (March 9) in the Annals of Internal Medicine.
WASHINGTON--Earth turned faster at the end of the time of the dinosaurs than it does today, rotating 372 times a year, compared to the current 365, according to a new study of fossil mollusk shells from the late Cretaceous. This means a day lasted only 23 and a half hours, according to the new study in AGU's journal Paleoceanography and Paleoclimatology.
Though not as prevalent in the atmosphere as carbon dioxide, methane is a far more potent greenhouse gas. Occurring naturally as well as being manmade, methane is much shorter-lived than CO2, but it is fast acting and 20 to 80 times as effective at trapping heat. A little extra methane goes a long way.
A corporation announces it's seeking bids from local governments to build a new warehouse or move its headquarters.
Policymakers tend to swoop in with this mindset: Let's entice that company with tax breaks to set up shop here. It'll create new jobs and enhance the overall health of our economy.
But economic development incentives may do more harm than good, especially for middle-class workers, according to new West Virginia University research.
