A little extra sugar can make us crave just about anything, from cookies to condiments to coffee smothered in whipped cream. But its sweetness doesn't fully explain our desire. Instead, new research shows this magic molecule has a back channel to the brain.
Increased time constraints and the need for convenience in raising children appear to offset parents' concerns about the future when it comes to their carbon footprints, according to new research by University of Wyoming economists and a colleague in Sweden.
The T2K Collaboration has published new results showing the strongest constraint yet on the parameter that governs the breaking of the symmetry between matter and antimatter in neutrino oscillations. Using beams of muon neutrinos and muon antineutrinos, T2K has studied how these particles and antiparticles transition into electron neutrinos and electron antineutrinos, respectively. The parameter governing the matter/antimatter symmetry breaking in neutrino oscillation, called δcp phase, can take a value from -180º to 180º.
A patient in the hospital for metastatic Hodgkin lymphoma with significant abdominal distention displayed sudden onset of ST-segment elevations--often an indicator of a heart attack--however the heart attack symptoms improved when the cardiovascular care team pressed on the abdomen during a standard exam, according to a case published in JACC: Case Reports.
What The Study Did: Older age for parents has been associated with autism spectrum disorders (ASDs) in children, however little is known about the association between the age of grandparents at the time of the birth of the parent and the risk of ASD in the grandchildren. This association was investigated in an observational study with the use of data from Danish national health registries that included three generations and 1.4 million children born from 1990 to 2013.
What The Study Did: Surveys from nearly 7,000 resident surgeons were used to evaluate how common racial/ethnic discrimination is in U.S. general surgery programs and how it's associated with burnout, thoughts of quitting and suicide.

ROCHESTER, Minn. -- Research indicates that widespread opioid overprescribing contributed to the opioid epidemic. New research shows that this dangerous trend has apparently been coupled with another: inappropriate use of high-potency opioids.
A multi-institution research collaboration led by Mayo Clinic will publish its findings Wednesday, April 15, in JAMA Network Open. The study showed that more than half of Americans starting the most highly regulated opioids might be receiving inappropriate treatment.
ST. PETERSBURG, Fla. (April 15, 2020)- Since the 2010 BP oil spill, marine scientists at the University of South Florida (USF) have sampled more than 2,500 individual fish representing 91 species from 359 locations across the Gulf of Mexico and found evidence of oil exposure in all of them, including some of the most popular types of seafood. The highest levels were detected in yellowfin tuna, golden tilefish and red drum.
CAMBRIDGE, MA -- MIT engineers have developed a way to closely track how plants respond to stresses such as injury, infection, and light damage, using sensors made of carbon nanotubes. These sensors can be embedded in plant leaves, where they report on hydrogen peroxide signaling waves.
April 15, 2020 - Rapidly escalating numbers of COVID-19 patients suffering from respiratory failure threaten to overwhelm hospital capacity and force healthcare providers into making challenging decisions about the care they provide. Of particular interest is the role of ECMO - extracorporeal membrane oxygenation, a form of life support for patients with advanced lung disease - to support critically ill patients in the current pandemic.
Bottom Line: A high-resolution, three-dimensional imaging technique, when combined with quantitative measurement of tissue elasticity, could accurately detect cancer within the resected margins of surgical specimens taken from patients undergoing breast-conserving surgery.

As per the WHO report, one in every four people are affected by a mental or neurological disorder at some point in their lives making mental disorders among the leading cause of ill-health and disability worldwide. In the present era of socioeconomic competition and related stress, there has been a significant rise in the incidence of neurological and psychiatric ailments especially depression, bipolar disorder, acute anxiety and panic attacks.
A plant-based diet is a good choice for both climate and health. However, many plant-based products, especially legumes, contain FODMAP compounds that are poorly digestible and cause unpleasant intestinal symptoms. A study by VTT and Finnish companies succeeded in breaking down FODMAPs with enzymes and producing new, stomach-friendly plant-based food products.
During learning, the brain is a prediction engine that continually makes theories about our environment and accurately registers whether an assumption is true or not. A team of neuroscientists from Ruhr-Universität Bochum has shown that expectation during these predictions affects the activity of various brain networks.

Evolutionary biology aims to explain how new species arise and evolve to occupy myriad niches - but it is not a singular or simplistic story. Rare bees found in high mountain areas of Fiji provide evidence that they have evolved into many species, despite the fact they can't readily adapt to different habitats.
These bees - discovered by a team of researchers from Flinders University, South Australian Museum, UniSA and University of Adelaide - serve as a major warning about the impact of ongoing human-induced climate change and loss of biodiversity for different species.
