At the interface of math and science
In popular culture, mathematics is often deemed inaccessible or esoteric. Yet in the modern world, it plays an ever more important role in our daily lives and a decisive role in the discovery and development of new ideas -- often behind the scenes.

Glaciers in the Grand Canyon of Mars?
For decades, planetary geologists have speculated that glaciers might once have crept through Valles Marineris, the 2,000-mile-long chasm that constitutes the Grand Canyon of Mars. Using satellite images, researchers have identified features that might have been carved by past glaciers as they flowed through the canyons; however, these observations have remained highly controversial and contested.

Single-neuron 'hub' orchestrates activity of an entire brain circuit
New Tel Aviv University research makes a major contribution to efforts to navigate the brain, offering a precise model of the organization of developing neuronal circuits. If researchers can further identify the cellular type of 'hub neurons,' it may be possible to reproduce them in vitro and transplant them into aged or damaged brain circuitries in order to recover functionality.

Scripps Research Institute scientists shed light on cause of spastic paraplegia
Scientists at The Scripps Research Institute have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The Scripps researchers found large droplets of triglycerides within the neurons of mice modeling the disease.

Scientists make droplets move on their own
Droplets are simple spheres of fluid, not normally considered capable of doing anything on their own. But now researchers have made droplets of alcohol move through water. In the future, such moving droplets may deliver medicines.

Scientists identify the signature of aging in the brain
Weizmann Institute researchers Prof. Michal Schwartz Dr. Ido Amit have found evidence of a unique 'signature' that may be the 'missing link' between cognitive decline and aging. The scientists believe that this discovery may lead, in the future, to treatments that can slow or reverse cognitive decline in older people.

New method to motivate students to reduce energy consumption

Experts from CNIO discover shining cells responsible for developing tumors
Researchers from the Spanish National Cancer Research Centre have discovered and characterized a new specific marker for cancer stem cells: riboflavin, or vitamin B2, a pigment that emits green fluorescence as a result of its accumulation inside intracellular vesicles. This light emission property, acts to track, isolate, and later purify it, without the need for antibodies or other more costly and complex techniques.

A molecular mechanism involved in cellular proliferation characterized
Researchers from Guillermo Montoya's team at the Spanish National Cancer Research Centre, in collaboration with Isabelle Vernos' Group from the CRG, have uncovered the molecular interaction between TACC3 and chTOG, key proteins in forming the internal cellular framework that enables and sustains cell division. Published today in Nature Communications, the observations may help to optimize current oncological therapies specifically designed to fight against this framework, named by the scientific community as microtubules.

Simulations reveal an unusual death for ancient stars
Certain primordial stars -- those 55,000 and 56,000 times the mass of our sun, or solar masses -- may have died unusually. In death, these objects -- among the universe's first generation of stars -- would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

Viral infection might just be a phase... transition
Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the rigid DNA packaged inside a virus flow into a cell? In two separate studies, Carnegie Mellon biophysicist Alex Evilevitch has shown that in viruses that infect both bacteria and humans, a phase transition at the temperature of infection allows the DNA to change from a rigid crystalline structure into a fluid-like structure that facilitates infection.

Predicting landslides with light
A team of researchers in Italy are expanding the reach of optical fiber sensors 'to the hills' by embedding them in shallow trenches within slopes to detect and monitor both large landslides and slow slope movements. The team will present their research at The Optical Society's (OSA) 98th Annual Meeting, Frontiers in Optics, being held Oct. 19-23 in Tucson, Ariz., USA.

AAN: Risks of opioids outweigh benefits for headache, low back pain, other conditions
According to a new position statement from the American Academy of Neurology, the risk of death, overdose, addiction or serious side effects with prescription opioids outweigh the benefits in chronic, non-cancer conditions such as headache, fibromyalgia and chronic low back pain. The position paper is published in the Sept. 30, 2014, print issue of Neurology, the medical journal of the American Academy of Neurology.

Scientists discover a new role for estrogen in the pathology of breast cancer
Scientists have discovered a previously unknown mechanism by which estrogen prepares cells to divide, grow and, in the case of estrogen-positive breast cancers, resist cancer drugs. The researchers say the work reveals new targets for breast cancer therapy and will help doctors predict which patients need the most aggressive treatment.
