Space Tourism Ship Crashes in Test Flight; 1 Pilot Dead

A spacecraft intended to carry tourists into space someday crashed this afternoon in California's Mojave desert, with one pilot dead and another injured, reports AP. "Our first concern is the status of the pilots," says a Virgin Galactic statement following the loss of its SpaceShipTwo craft. NBC News reports that...

Tau, not amyloid-beta, triggers neuronal death process in Alzheimer's

WASHINGTON — New research points to tau, not amyloid-beta (Abeta) plaque, as the seminal event that spurs neuron death in disorders such as Alzheimer's disease. The finding, which dramatically alters the prevailing theory of Alzheimer's...Show More Summary

Quote of the Week – climate fears in context

A dear friend sent me a note the other day that I thought was prescient, as it relates to the alarmism side of climate, where we see fear stories being propagated by the media on an almost daily basis. So with permission, I repeat it here. Fears are all subject to the climate, just sometimes…

Ancient Meteorites Change Story of Earth's Water

At least when it comes to life as we know it, water is a basic requirement. So a new analysis of meteorites suggesting that water could have appeared on Earth 14 million years after the start of solar system some 4.6 billion years ago—more than a hundred million...

Fun and games make for better learners

Four minutes of physical activity can improve behaviour in the classroom for primary school students, according to new research by Brendon Gurd. A brief, high-intensity interval exercise, or a "FUNterval," for Grade 2 and Grade 4 students reduced off-task behaviours like fidgeting or inattentiveness in the classroom. read more

Avivagen publishes evidence for natural alternative to antibiotic use in livestock

Today the leading journal PLOS ONE published research that provides underlying scientific support for a fundamentally new type of natural alternative to the use of antibiotics in livestock feeds for growth promotion and disease prevention. Show More Summary

Drug tests on mothers' hair links recreational drug use to birth defects

Drug tests on 517 mothers in English inner city hospitals found that nearly 15% had taken recreational drugs during pregnancy and that mothers of babies with birth defects of the brain were significantly more likely to have taken drugs than mothers with normal babies. The study found no significant links between recreational drug use and any other type of birth defect. read more

Last Chance to Send Your Name to Mars!

If you’ve concluded that a one-way ticket to Mars isn't for you, there's a tamer alternative: Send your name to Mars instead. Today's the last day to sign up to get your moniker on a "dime-sized microchip" that's being blasted into space on the Orion spacecraft, NASA reports. The first...

Decoding the emergence of metastatic cancer stem cells

In the first study of its kind, Rice University researchers have mapped how information flows through the genetic circuits that cause cancer cells to become metastatic. The research reveals a common pattern in the decision-making that allows cancer cells to both migrate and form new tumors. Show More Summary

Cell division, minus the cells

The process of cell division is central to life. The last stage, when two daughter cells split from each other, has fascinated scientists since the dawn of cell biology in the Victorian era. For just as long, it has been notoriously difficult to study this final step, when the dividing cell creates a furrow before cleaving in two. read more

Is fleet diversity key to sustainable fisheries?

Santa Barbara, Calif. — Concern about fisheries is widespread around the world. Over the past several decades, a robust discussion has taken place concerning how to manage fisheries better to benefit ecosystems and humans. Much of the discussion has focused on preserving biological diversity, a critical component of healthy ecosystems. Show More Summary

NASA sees remnants of Nilofar go to cyclone graveyard

Wind shear has caused the demise of former Tropical Cyclone Nilofar in the northern Arabian Sea. NASA's Aqua satellite passed over Nilofar on Oct. 31 and captured an image that shows strong wind shear has pushed the bulk of clouds and showers away from Nilofar's center, basically sending the storm to its grave. read more

Proton therapy shown to be less costly than some alternative radiotherapy techniques

In terms of duration of treatment and cost, patients with early stage breast cancer may benefit from accelerated partial breast irradiation (APBI) with proton therapy versus whole breast irradiation (WBI), according to new research from The University of Texas MD Anderson Proton Therapy Center. read more

Green spaces don't ensure biodiversity in urban areas

Planting trees and creating green space in cities is good for attracting species, but it may not be enough to ensure biodiversity in built environments, a University of Iowa study has found. read more

Improved mouse model will accelerate research on potential Ebola vaccines, treatments

In the war against Ebola one important hurdle has just been cleared – by a mouse. Researchers at the University of North Carolina at Chapel Hill and colleagues have developed the first genetic strain of mice that can be infected with Ebola and display symptoms similar to those that humans experience.

There and back again: Extending optical storage lifetime by retrieving photon echoes from semiconductor spin excitations

(Phys.org) —For all of their differences, classical and quantum communication have at least one thing in common: the importance of being able to store optical information. That being said, optical storage is a complex process that depends...Show More Summary

Captive rhinos exposed to urban rumbles

WASHINGTON, D.C., October 31, 2014 -- The soundtrack to a wild rhinoceros's life is wind passing through the savannah grass, birds chirping, and distant animals moving across the plains. But a rhinoceros in a zoo listens to children screaming, cars passing, and the persistent hum of urban life. read more
