Their results provide clues to the molecular apparatus that is involved in conscious thinking in brains.
Americans waste nearly a pound of food per person each day, but the exact amount of food we trash differs by how healthy your diet is, new research finds. Annually, food waste corresponds with the use of 30M acres of land (7% of total US cropland) and 4.2 trillion gallons of water. Surprisingly, higher quality diets were associated with higher levels of food waste.

Scientists have long wondered why the physical traits of Neanderthals, the ancestors of modern humans, differ greatly from today’s man. In particular, researchers have deliberated the factors that necessitated early man’s forward-projecting face and oversized nose. As published in the April 4 edition of The Royal Proceedings Society B, an international research team led by a professor at the University of New England in Australia, with the aid of an anatomy and fluid dynamics expert at NYIT College of Osteopathic Medicine at Arkansas State University (NYITCOM at A-State), may have the answer.
Mayo Clinic的一项研究发现没有任何证据支持接受麻醉anesthesia的三岁以前的儿童的智商会低于没有接受麻醉的儿童。 而更复杂的结果出现在接受多次麻醉的儿童群体中：尽管他们在智力上与其他儿童没有区别，但他们在测量精细运动技能的测试中得分较低，并且他们的父母也更可能会报告他们有行为和学习上的问题。 以上这些发现发表在《麻醉学》（Anesthesiology）杂志上。
Researchers at the University of Minnesota and The Dow Chemical Company have joined forces to tackle one of the biggest challenges in health care—how to get life-saving medicines to work faster and better with fewer side effects.

Explosives have an inherent problem - they should be perfectly safe for handling and storage but detonate reliably on demand.
Engineers discovered that tiny crystal lattices called “self-assembling molecular nanosheets” expand when exposed to light. The advancement could form the backbone of new light-powered actuators, oscillators and other microscopic electronic components useful in the development of artificial muscles and other soft robotic systems.
University of Georgia food scientist Xiangyu Deng has created a system that can identify foodborne pathogens in a fraction of the time taken by traditional methods.
Decades of clinical and pre-clinical studies have demonstrated that chronic drinking leads to long-lasting changes in reward- and stress-related neuronal circuitry. The nucleus accumbens (NAc) is an important part of this circuitry. Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) are commonly used by neuroscientists to identify signals in nerve circuits that specify certain behaviors, perceptions, emotions, innate drives, or motor functions. This rodent study investigated the effects of DREADDs on nerve cell activity in the NAc (comprised of a core and a shell) in relation to binge-like drinking.
A study published in JNCCN estimates costs for people age 18 and up, ranks the price tags of the top four cancer types, and highlights potential cost-saving benefits of prevention and screening.
Interventions such as speeding enforcement and formal swimming lessons for young children could potentially save more than 250,000 lives a year if they were implemented across populations living in extreme poverty in low- and middle-income countries, according to a new study from researchers at the Johns Hopkins Bloomberg School of Public Health.
Maintaining a stocked cart, with a full supply of the life-saving drug dantrolene, to treat malignant hyperthermia, a rare but potentially fatal adverse reaction to general anesthesia, may not be cost-beneficial in hospital maternity units where the incidence of the reaction is low.
In a new analysis of interviews conducted with children who have asthma, their caregivers and their clinicians, Johns Hopkins researchers found that there was significant lack of agreement about why the kids miss their needed daily anti-inflammatory medication.
We might think of roots as necessary, but uninteresting, parts of the crop production process. New research, however, focuses on what’s going on in the soil with the plant’s roots and the chemicals they produce.
Women still at higher risk; new research could improve prevention
In a new study published in the Journal of the Royal Society Interface, researchers Albert Kao (Harvard University), Andrew Berdahl (Santa Fe Institute), and their colleagues examined just how accurate our collective intelligence is and how individual bias and information sharing skew aggregate estimates. Using their findings, they developed a mathematical correction that takes into account bias and social information to generate an improved crowd estimate.
Are indoor tanners taking measures to prevent skin cancer? A researcher from Rutgers Cancer Institute of New Jersey and colleagues at Fox Chase Cancer Center found a majority of the indoor tanners analyzed in this study are not taking part in skin cancer screening.
Using computer models and laboratory rats, Johns Hopkins researchers have demonstrated that “direct electrical current” can be delivered to nerves preferentially, blocking pain signals while leaving other sensations undisturbed.
Warmer summer and fall seasons and fewer winter freeze-thaw events have led to changes in the relative numbers of different types of bugs in the Arctic. The study relies on the longest-standing, most comprehensive data set on arctic arthropods in the world today: a catalogue of almost 600,000 flies, wasps, spiders and other creepy-crawlies collected at the Zackenberg field station on the northeast coast of Greenland from 1996-2014.

New research from the University of Arkansas Music Cognition Laboratory gives insight into how the brain judges music quality.
Un estudio de Mayo Clinic no descubrió ninguna evidencia respecto a que los niños a quienes se les administra anestesia antes del tercer cumpleaños tengan menos coeficiente intelectual que aquellos que no la reciben.
The research team analyzed muscle biopsies of young adults with and without Type 1 diabetes who exceed Diabetes Canada's recommended weekly levels for physical activity. The researchers found structural and functional changes in the power generation parts of the cell, or mitochondria, of those with diabetes. Not only were the mitochondria less capable of producing energy for the muscle, they were also releasing high amounts of toxic reactive oxygen species, related to cell damage.
ROCHESTER, Minn. – A Mayo Clinic study finds no evidence that children given anesthesia before their third birthdays have lower IQs than those who did not have it. A more complex picture emerges among people who had anesthesia several times as small children: Although their intelligence is comparable, they score modestly lower on tests measuring fine motor skills, and their parents are more likely to report behavioral and learning problems. The findings are published in Anesthesiology
Investigators at Cedars-Sinai are exploring a new way to treat amyotrophic lateral sclerosis (ALS) by transplanting specially engineered neural cells into the brain. Their new study shows the transplanted cells delayed disease progression and extended survival in animal models.

Can medical marijuana help to fight the opioid epidemic? Many believe that it can. But a new study finds that people who use medical marijuana actually have higher rates of medical and non-medical prescription drug use—including pain relievers. The study appears in the Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine (ASAM), published by Wolters Kluwer.
Researchers at the UC Davis MIND Institute have found that children with autism spectrum disorder (ASD) have reduced immune system regulation, as well as shifts in their gut microbiota. The immune deregulation appears to facilitate increased inflammation and may be linked to the gastrointestinal issues so often experienced by children with ASD. The research was published in the journal Brain, Behavior, and Immunity.
UC San Diego biologists have created the world’s first gene drive system—a mechanism for manipulating genetic inheritance—in Drosophila suzukii, an agricultural pest that has invaded much of the United States and caused millions of dollars in damage to high-value berry and other fruit crops.
