WSU researchers tackle ‘virtually ignored’ psychological study of spite

In spite of spite’s large and small impacts, and the obvious power it can hold on the human psyche, it has been ‘virtually ignored’ by social, personality and clinical psychologists, Marcus said in a recent paper, ‘The Psychology of Spite and the Measurement of Spitefulness,’ in the journal Psychological Assessment. David Marcus and colleagues have attempted to remedy that oversight by measuring spitefulness with a test similar to those used for other personality traits.

Liquid spacetime

If spacetime were a fluid, it would have very low viscosity, just like a ‘superfluid.’ A study carried out jointly by the International School for Advanced Studies of Trieste and the Ludwig-Maximilian University of Munich shows how the ‘atoms’ making up the fluid of spacetime should behave, according to models of quantum gravity. The considerations suggested in this study impose very strong constraints on the occurrence of effects related to this possible ‘fluid’ nature of spacetime.

The surface area of the digestive tract ‘only’ as large as a studio apartment

The internal surface area of the gastro-intestinal tract has long been considered to be between 180 and 300 square meters. Scientists at the Sahlgrenska Academy have used refined microscopic techniques that indicate a much smaller area. ‘Actually, the inner surface of the gastro-intestinal tract is only as large as a normal studio apartment,’ says scientist Lars Fändriks.

Mars Missions Could Make Humanity a Multi-Planet Species, NASA Chief Says

Mars Missions Could Make Humanity a Multi-Planet Species, NASA Chief SaysIn order for humanity to survive into the distant future, we need to visit and learn how to survive on other worlds, according to NASA chief Charles Bolden. NASA is in the process of developing technologies that are expected to help humans get to Mars and beyond. Landing astronauts on Mars and even establishing a long-term human presence on the Red Planet is just one step toward learning how to live on a different world, Bolden said during the Humans 2 Mars Summit in Washington, D.C., Tuesday (April 22). Ideally, the first crewed mission to Mars will represent the culmination of many incremental steps — like NASA's ambitious plan to retrieve an asteroid and park it near the moon — taken to safely get humans to and from Mars, NASA officials have said.

Spacewalkers to replace failed computer outside space station

Backdropped by the blackness of space, the International Space Station is seen in this image taken by a crew member aboard the Space Shuttle Atlantis.Two U.S. astronauts floated outside the International Space Station on Wednesday to replace a failed computer that serves as a backup to critical control systems, including the outpost's solar panel wings. Flight engineers Rick Mastracchio and Steve Swanson left the station's Quest airlock just after 10 a.m. EDT (1400 GMT) for what was expected to be a 2-1/2-hour spacewalk. They carried with them a spare computer to be installed in the central section of the station's exterior power truss. "It looks like a great day to take a walk in space," Canadian astronaut Jeremy Hansen radioed to the crew from NASA's Mission Control in Houston.

Ah-CHOO! 3 Snortworthy Facts About Sneezes

Sneezes are one of the body’s natural defense mechanisms against foreign invaders, protecting the lungs and other organs from contamination. Sneezes begin when respiratory epithelium, which is the layer of cells that line the nose, becomes irritated and triggers the ending of the trigeminal cranial nerve, which then tells the brain to initiate the sneeze reflex. In fact, 1 in 4 people sneeze in bright sunlight, known as the photic sneeze reflex, or by the cleverly contrived name, autosomal dominant compelling helio-opthalmic outburst, or ACHOO, syndrome.

Parkinson’s Drug Shows Promise in Preventing Breast Cancer

Women with mutations in the BRCA1 gene are at high risk for breast and ovarian cancer, and there are currently no drugs proven to reduce their cancer risk. One drug, called benserazide, is currently used for Parkinson’s disease, and in studies it reduced the formation of breast tumors in mice that had been implanted with cancer cells containing the BRCA1 gene mutation. All of the mice that did not receive the drug developed breast tumors, but 40 percent of mice given the drug were tumor-free, said study researcher Elizabeth Alli, of Stanford University School of Medicine. Some studies show that women with mutations in the BRCA1 gene have a 50 to 70 percent chance of getting breast cancer by age 70, compared with a 12 percent lifetime risk for the average American woman.

US Astronauts Taking Spacewalk to Fix Space Station Today: Watch Live

US Astronauts Taking Spacewalk to Fix Space Station Today: Watch LiveTwo American astronauts will venture outside the International Space Station today to replace a dead computer that serves vital systems on the orbiting laboratory, and you can watch their spacewalk live online. NASA astronauts Rick Mastracchio and Steve Swanson are due to float outside the space station at 9:20 a.m. EDT (1320 GMT) and spend nearly three hours on the computer swap. Mastracchio and Swanson plan to spend 2.5 hours replacing a backup computer known in NASA parlance as a Multiplexer-Demultiplexer, or MDM. The device is a backup computer for routing commands to systems supporting the space station's solar arrays, robotic arm rail car and other critical systems along the station's backbone-like main truss.

California GOP hopeful wants free college for science, math students

California Republican gubernatorial candidate Kashkari poses after touring the Robinson Helicopter Co. in TorranceBy Jennifer Chaussee BERKELEY, California (Reuters) – California Republican gubernatorial hopeful Neel Kashkari called for free college tuition for students pursuing math and science degrees, part of an education reform plan released Tuesday that would also model public schools after charter schools. Kashkari's proposal would waive tuition for students pursuing a four-year degree in any science, technology, electronics, or math subject in exchange for a percentage of their future earnings after graduation. It came as Kashkari, trailing a distant third in recent polls behind incumbent Jerry Brown and Republican Tea Party favorite Tim Donnelly, is struggling to add momentum to his campaign before the June primary.

Is Global Warming a Giant Natural Fluctuation? (Op-Ed)

Is Global Warming a Giant Natural Fluctuation? (Op-Ed)Shaun Lovejoy is a professor of physics at McGill University and president of the Nonlinear Processes Division of the European Geosciences Union. Last year, the Quebec Skeptics Society threw down the gauntlet: "If anthropogenic global warming is as strong as scientists claim, then why do they need supercomputers to demonstrate it?" My immediate response was, "They don't." Indeed, in 1896 — before the warming was perceptible — the Swedish scientist Svante Arrhenius, toiling for a year, predicted that doubling carbon dioxide (CO2) levels would increase global temperatures by 5 to 6 degrees Celsius, which turns out to be close to modern estimates. Yet the skeptics' question resonated: Global Circulation Models (GCM's) dominate climate research to such an extent that (even scientists!) can be forgiven for thinking these computer-driven models are essential. So I took up the challenge, and my answer appears in the research described in a paper recently published in the journal Climate Dynamics.

Study in Europe eclipses notion home in the sun equals happiness

A woman sits by the rocks at the Ramizzo beach in the so called "Emerald Coast" of the Sardinia islandSun seekers who leave northern Europe for warmer climes are marginally less happy than those left behind, a study found. A sample of more than 300 migrants from Belgium, Switzerland, Germany, the Netherlands, France and Britain who resettled in Mediterranean countries found that they were slightly less satisfied with life than a much larger sample of 56,000 people living in northern countries. The sun lovers scored 7.3 out of a possible 10 on average on a "happiness" scale while the stay-at-homes came in at an average of 7.5 percent, according to the study released on Wednesday by Dr David Bartram, a senior lecturer in the Department of Sociology at England's University of Leicester. "The key finding from the analysis is that people from northern Europe who migrated to southern Europe are less happy than the stayers in northern Europe," Bartram said.
