Decision making is the process of making choices by setting goals, gathering information, and assessing alternative occupations. Problem solving and decision-making are important skills for business and life. Problem-solving often involves decision-making, and decision-making is especially important for management and leadership. There are processes and techniques to improve decision-making and the quality of decisions. Decision-making is more natural to certain personalities, so these people...

  1. Nuts Nuts are loaded with healthy monounsaturated fats, proteins, fiber, nutrients, vitamins, and antioxidants. One should include a handful of nuts in daily diet. Peanuts, walnuts, hazelnuts, almonds, pistachios, pecans, and other nuts reduce blood cholesterol. Studies have revealed that eating a quarter cup of almonds a day can lower LDL by 4.4 percent. Moreover, you can consume some roasted almonds without oil. Walnuts contain high levels of omega-3 fatty acids. Chomp them to ...

EyeRing is a wearable, intuitive interface that allows a person to point at an object to see or hear more information about it. We came up with the idea of a micro-camera worn as a ring on the index finger with a button on the side, which can be pushed with the thumb to take a picture or a video that is then sent wirelessly to a mobile phone to be analyzed. The user tells the system what information they are interested in and receives the answer in either auditory or visual form. The device also...

Biochemist Daniel Nocera has been working for decades on an "artificial leaf" — a silicon wafer that can create energy from sunlight and water the way real leaves do. HARVARD SCIENTISTS have created a “bionic leaf” that converts solar energy into a liquid fuel. The work—a proof of concept in an exciting new field that might be termed biomanufacturing—is the fruit of a collaboration between the laboratories of Adams professor of biochemistry and systems biology Pamela Silver at Harvard Medical...

Irreducible complexity (IC) is a pseudoscientific argument that certain biological systems cannot be evolved by successive, slight modifications to a functional precursor system through natural selection acting upon a series of advantageous naturally occurring chance mutations. Michael Behe, a professor of biochemistry at Lehigh University, first argued that irreducible complexity made evolution purely through natural selection of random mutations impossible. However, evolutionary biologists ...

A GMO is a plant developed through a process in which a copy of a desired gene or section of genetic material from one plant or organism, such as the ability to use water more efficiently, is placed in another plant. The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an international agreement on biosafety as a supplement to the Convention on Biological Diversity effective since 2003. The Biosafety Protocol seeks to protect biological diversity from the potential...

A new NOAA study, published in the journal Ecological Modeling, forecasts an increase in ciguatera fish poisoning in the Gulf of Mexico and the U.S. Southeast Atlantic coast with predicted rising global ocean temperatures due to climate change. People can be affected by ciguatera, the most common form of algal-induced seafood poisoning, by eating contaminated tropical marine reef fish such as grouper, snapper and barracuda. Scientists are now predicting that global climate change will ciguatera,...

The Grove Ecosystem is an intelligent indoor garden that enables people to grow fresh, flavorful, and healthy food year-round. The ecosystem contains an aquarium, where fish eat food and turn it into waste. Bacteria take that waste and turn it into nitrates, which is a critical fertilizer for plants. A plumbing system pumps the nitrate-enriched water through the plant beds, creating a self-enclosed ecosystem. This symbiosis between fish, plants, and bacteria is called aquaponics. The ecoystems c...

Scientists studying penguins’ feathers have revealed how the birds stay ice free when hopping in and out of below zero waters in the Antarctic. Penguins living in the Antarctic are highly evolved to cope with harsh conditions, their short outer feathers overlap to make a thick protective layer over fluffier feathers which keep them warm. Under their skin, a thick layer of fat keeps them insulated. The flightless birds spend a lot of time in the sea and are extremely agile and graceful swimmers, ...

After 36 days of battling sharks that kept biting their equipment, scientists have returned from the remote Pacific Ocean with a new way of looking at the world’s largest and possibly most mysterious volcano, Tamu Massif. The team has begun making 3-D maps that offer the clearest look yet at the underwater mountain, which covers an area the size of New Mexico. In the coming months, the maps will be refined and the data analyzed, with the ultimate goal of figuring out how the mountain was formed....

Researchers at Purdue University in West Lafayette, Indiana are studying Ants to come up with new ways to get rid of them. One of the most common house ant species might have been built for living in some of the smallest spaces in a forest, but the ants have found ways to take advantage of the comforts of city living. Grzegorz Buczkowski, a Purdue University research assistant professor of entomology, found that odorous house ant colonies become larger and more complex as they move from forest...

Technology has dramatically changed our life even our way of eating. We would post the food we eat on social media and we even use applications to know where the best place to chow down is. An interactive crowd-sourced map ca...

A new study has found that fish have emotions. The study, published in Proceedings of the Royal Society B, found that zebrafish responded to stress by an increase in body temperature, or what it known as an “emotional fever.” It’s been suggested that such a thing only exists in mammals, birds and reptiles, but the new research proves otherwise. Scientists placed six zebrafish groups in tanks divided by plexiglass into six chambers, each containing water of a different temperature. Each tank w...

The Mediterranean fruit fly, or medfly, is an invasive species that is now endemic to Western Australia. The female medfly “stings” fresh fruit and then lays her eggs in the puncture site. The hatching larvae then feast on the decomposing fruit. A British bioengineering firm called Oxitec has created genetically modified medflies that, when released into the environment, could mate with wild fruit flies and pass on a gene that would prevent their female offspring from reaching adulthood which wo...

Genome sequencing confirms that myxozoans, a diverse group of microscopic parasites that infect invertebrate and vertebrate hosts, are actually “highly reduced” cnidarians, the phylum that includes jellyfish, corals and sea anemones. “This is a remarkable case of extreme degeneration of an animal body plan,” said Paulyn Cartwright, associate professor of ecology and evolutionary biology at KU and principal investigator on the research project. “First, we confirmed they’re cnidarians. Now we need...

This was the finding of a study led by Johns Hopkins Bloomberg School of Public Health in Baltimore, MD, and published in the journal Environmental Research. Previous research has already established that the DNA of cord blood from newborns is altered if the mother smokes during pregnancy. The difference is not in the genetic code itself but in the presence of "epigenetic" marks left on the DNA at 26 locations of the genome. Epigenetic markers are molecules that attach to genes and influence the...

Over the past couple of hundred years, the strength of the Earth’s geomagnetic field has been waning, leading scientists to wonder if our planet’s polarity is on the verge of flipping. A new study suggests this won’t happen in the near future and that the intensity of today’s field is uncharacteristically strong. Predicting a geomagnetic flip is important for two primary reasons, one biological, one technological. The Earth’s magnetic field deflects solar wind and cosmic rays, so with a weakened...

Ants are well-known for building with their bodies, but a new study has shown that army ants can optimize traffic flow using bridges that move. Army ants are a predatory nomadic species, they raid other insect colonies and are always on the move, without a permanent nest. In this lifestyle, finding the shortest foraging path with sufficient workforce left over is crucial. The new research shows they adjust their bridges to find that balance. A gap in an ant’s path might be a daunting obstacle fo...

Scientists suggest that global warming could progress faster than was previously believed because increased temperatures influence natural greenhouse gas emissions. Numerous studies from the Swedish research team over the past two years have determined that natural greenhouse gas emissions will increase when the climate gets warmer, Linköping University reported.  Now, their most recent study has backed up these findings. "Everything indicates that global warming caused by humans leads to increa...

ESO’s VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared. Just counting the number of galaxies in a patch of sky provides a way to test astronomers’ theories of galaxy formation and evolution. However, such a simple task becomes increasingly hard as astr...

Dr Ken Caldeira of Carnegie Institution and Dr Michael Rampino of New York University offer new support linking the age of these craters with recurring mass extinctions of life, including the demise of the dinosaurs. Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers. Specifically, they show a cyclical pattern over the studied period, with both impacts and extinction events taking place every 26 million years. This cycle has been linked...

In many ways stars are like living beings. They’re born, they live, they die and they even have a heartbeat. Using a novel technique, astronomers have detected thousands of stellar “pulses” in the galaxy Messier 87 (M87). Their measurements offer a new way of determining a galaxy’s age. We tend to think of stars as stable and unchanging. However, late in life stars like the Sun undergo a significant transformation. They become very bright and swell up to an enormous size, swallowing any planets ...

Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications. Nanoparticles, which are generally one thousand times smaller than the width of a human hair, are difficult to separate from plasma, the liquid ...

Mars’ largest moon, Phobos, is slowly falling toward the planet, but rather than smash into the surface, it likely will be shredded and the pieces strewn about the planet in a ring like the rings encircling Saturn, Jupiter, Uranus and Neptune. Mars could gain a ring in 10-20 million years when its moon Phobos is torn to shreds by Mars gravity. Though inevitable, the demise of Phobos is not imminent. It will probably happen in 20 to 40 million years, leaving a ring that will persist for anywhere ...

Researchers in the School of Chemistry and Chemical Engineering at Queen’s, along with colleagues at the University of Liverpool, UK, and other, international partners, have invented the new liquid and found that it can dissolve unusually large amounts of gas, which are absorbed into the ‘holes’ in the liquid. Porous materials, as their name would suggest, are materials with holes. These are materials that look totally solid to the naked eye, but on a molecular level, contain lots of empty space...

Pluto may have two ice volcanoes that spew water ice, nitrogen, ammonia, and methane onto the dwarf planet's surface, NASA announced today. The potential volcanoes were spied near Pluto's South Pole, in images taken by NASA's New Horizons spacecraft during its July flyby. NASA scientists used the photos to measure the mountains, they are several miles high and tens of miles wide, with large holes in their summits. "On Earth that generally means one thing a volcano," said Oliver White, New Horizo...

Sea-dwelling mollusks called chitons have armor-plated eyes embedded in their shells, and this incredible feature could provide a model for protective armor that could be used by the army and workers exposed to dangerous conditions. The chitons, or Acanthopleura granulates, have hundreds of these armored eyes on the surface of their shells, MIT reported. Unlike most eyes in the biological world that are made primarily of protein, these eyes are made of the mineral aragonite, but can still form f...

Researchers have developed a process to remove contaminants from oil sands wastewater using only sunlight and nanoparticles that is more effective and inexpensive than conventional treatment methods. Frank Gu, a professor in the Faculty of Engineering at the University of Waterloo and Canada Research Chair in Nanotechnology Engineering, is the senior researcher on the team that was the first to find that photocatalysis , a chemical reaction that involves the absorption of light by nanoparticles ...

New study proves that sense of taste is hardwired in the brain, independent of learning or experience. Most people probably think that we perceive the five basic tastes sweet, sour, salty, bitter and umami (savory) with our tongue, which then sends signals to our brain “telling” us what we’ve tasted. However, scientists have turned this idea on its head, demonstrating in mice the ability to change the way something tastes by manipulating groups of cells in the brain. “Taste, the way you and I th...
