NASA is considering a return trip to the most hotly-contested body in our solar system and has awarded funding to the Southwest Research Institute (SwRI) to study the cost and feasibility of an orbiter mission to Pluto.
Following the success of the New Horizons mission which visited Pluto in 2015 and then traveled on to visit Kuiper Belt Objects (KBOs) including the most distant object ever explored, Ultima Thule, scientists want to go back to the dwarf planet to learn more about it. New Horizons had a limited payload so it could only perform a cursory analysis of Pluto and its moons. The new mission would involve sending a craft into orbit around the dwarf planet to gather data and hopefully answer some of the questions raised by the earlier mission.
NASA is funding the study as part of the Planetary Science Decadal Survey, a document that explores key questions in planetary science and is published every 10 to 15 years. The study will form part of the next survey, which is set to begin in 2020.
A 14-year-old Pennsylvania girl has come up with an innovative way to get rid of blind spots before she can even legally get behind the wheel.
Alaina Gassler, from West Grove, presented her project — called ‘Improving Automobile Safety by Removing Blind Spots’ — during this year’s Society for Science and Public’s Broadcom MASTERS (Math, Applied Science, Technology and Engineering for Rising Stars).
Gassler won the Samueli Foundation Prize for her creativity — and a hefty $25,000 check. More than $100,000 was given out to 30 finalists at the award ceremony.
A Portland teen won second place in a national technology contest, taking home $2,500 that he can use to attend science camp next summer.
Rishab Jain, 14, is a freshman at Westview High School. His winning project, which he calls the Pancreas Detective, is an artificial intelligence tool that can help diagnose pancreatic cancer through gene sequencing. The algorithm helps doctors focus on the organ during examinations, which is often obscured because it moves around the abdominal area as patients breathe and other bodily functions shift other organs as well.
Last year, the same project netted $25,000 from 3M when he attended Stoller Middle School. He used that money to fund his nonprofit, Samyak Science Society, which promotes science, technology, engineering and math education for other children, Time Magazine reported.
Unlike chemotherapy or radiation, which attack cancer directly, CAR-T engineers patients’ immune cells so they can do it themselves. T-cells are removed from the blood and given new genes that produce receptors that let the T-cells recognize and bind to leukemia cells with a specific protein, CD19.
The genetically modified T-cells are then multiplied in the lab and infused back into the patient, where they ideally multiply even further and begin to target and kill cancer cells with CD19.
An Antares rocket from Northrop Grumman has successfully launched the Cygnus cargo spacecraft on its way to the International Space Station. The launch happened at 9:59AM from the Mid Atlantic Regional Spaceport as anticipated. Assuming nothing unusual happens, NASA says the cargo vessel will arrive at the ISS on Monday, November 4, carrying a huge load of supplies and scientific materials.
“While researching epilepsy, neuroscientist Itzhak Fried stumbled on a ‘mirth’ center in the brain — given this, what ought we be doing to combat extreme suffering and promote wellbeing?”
David Pearce — The Anatomy of Happiness… While researching epilepsy, neuroscientist Itzhak Fried stumbled on a ‘mirth’ center in the brain — given this, what ought we be doing to combat extreme suffering and promote wellbeing?
If one finds oneself viscerally hostile to the idea of universal happiness, and if by contemporary standards one falls within the statistically normal range in one’s emotional repertoire, then just how seriously should one contemplate the following possibility? Today we are the victims of what our successors will reckon an atavistic mood disorder. This disorder infects all our thoughts as well as all our feelings and volitions. It is a historical condition no less epistemically defective than are dream-psychoses from the perspective of the waking state.
Is the worry one might be locked in such an affective psychosis just the product of idle scepticism? Given the cognitive inaccessibility of most of the generically ecstatic states alluded to here, perhaps one wouldn’t know if one were so afflicted. After all, damaged and disfigured minds may have limited self-insight. Nor would one necessarily have the conceptual resources even to grasp what was at stake if one suffered from such a neural deficit. Pure, “unearned”, genetically-driven bliss of even the mildest flavour detracted from the inclusive fitness of one’s genes in the ancestral environment. Constitutionally happy freaks-of-nature got eaten or outbred. Hence unipolar euphoric mania today is vanishingly rare; unipolar melancholic depression and chronic dysthymia are all too common. Is one’s potential unease, if not revulsion, at the prospect of paradise-on-earth an incidental cultural by-product of natural selection? Or has selection pressure ensured that one is genetically predisposed to be biased against the idea of enduring bliss in the first instance?
Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.
“Right now, whatever is available as a clinical product is more like a fancy Band-Aid,” said Pankaj Karande, an associate professor of chemical and biological engineering and member of the Center for Biotechnology and Interdisciplinary Studies (CBIS), who led this research at Rensselaer. “It provides some accelerated wound healing, but eventually it just falls off; it never really integrates with the host cells.”
A significant barrier to that integration has been the absence of a functioning vascular system in the skin grafts.
Oct. 29 is World Stroke Day. Sometimes called a brain attack, stroke is the second leading cause of death worldwide and the fifth leading cause of death in the U.S. Men and women are at risk of a stroke, but women are more likely to have – and die – of a stroke than men. Dr. Kara Sands, a Mayo Clinic neurologist, says stroke kills twice as many women as breast cancer. The good news is that strokes are preventable, treatable and beatable.
