Terahertz spectroscopy goes nano

Mié, 10/18/2017 - 22:00
Brown University researchers have improved the resolution of terahertz emission spectroscopy -- a technique used to study a wide variety of materials -- by 1,000-fold, making the technique useful at the nanoscale.

Fundamental research enhances understanding of major cancer gene

Mié, 10/18/2017 - 22:00
A collaboration between Babraham Institute scientists and AstraZeneca provides new insights into the role of PTEN, a major cancer gene, in controlling cell growth and behaviour. PTEN is the second most commonly altered gene in human cancers, particularly prostate cancers, and this work could help to develop and target new treatments.

Insulin signaling molecule in liver controls levels of triglyceride in blood

Mié, 10/18/2017 - 22:00
A new animal study shows how insulin controls the movement and storage of fat molecules in the liver and how a breakdown in this system could lead to non-alcoholic fatty liver disease and changes in circulating lipid levels associated with cardiovascular disease.

Cleaning up? Not without helpers

Mié, 10/18/2017 - 22:00
Freiburg scientists explain assembly and transport function of 'old' calcium pumps by 'new' partner proteins.

Strange but true: Turning a material upside down can sometimes make it softer

Mié, 10/18/2017 - 22:00
Through the combined effect of flexoelectricity and piezoelectricity, researchers at the ICN2 led by ICREA Gustau Catalán in collaboration with the UAB have found that polar materials can be made more or less resistant to dents when they are turned upside down... or when a voltage is applied to switch their polarization. This research points to the future development of 'smart mechanical materials' for use in smart coatings and ferroelectric memories.

What the Balkans can teach other states in conflict

Mié, 10/18/2017 - 22:00
What the Balkans can teach other states in conflict Research at the University of Kent into how areas like the Balkans have developed ways to address the challenges of their past -- including ethnic cleansing -- offers a toolkit for others facing similar conflict. the section includes contributions from around the world and focuses on consultation processes and innovative methods to examine the views of victims.

Self-portrait of NASA's James Webb Space Telescope marks critical test

Mié, 10/18/2017 - 22:00
What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA's James Webb Space Telescope in Chamber A at NASA's Johnson Space Center in Houston. The photo was used to verify the line of sight (or path light will travel) for the testing configuration.

Study examines the effects of sexual harassment, assault on researchers' careers

Mié, 10/18/2017 - 22:00
Investigators who previously reported on sexual harassment and assault during academic fieldwork have now shed light on the effects of such violations on individuals and their career trajectories.

Solid or liquid? Researcher proposes a new definition of glass

Mié, 10/18/2017 - 22:00
The glass is a non-equilibrium, non-crystalline state of matter that appears solid on a short time scale but relaxes toward the liquid state, proposes Brazilian scientist. The inspiration for the new definition occurred to him after giving the Turner Memorial Lecture at the Society of Glass Technology (SGT) Centenary Conference, in Sheffield (UK).

Itsy bitsy spider: Fear of spiders and snakes is deeply embedded in us

Mié, 10/18/2017 - 22:00
Snakes and spiders evoke fear and disgust in many people, even in developed countries where hardly anybody comes into contact with them. Until now, there has been debate about whether this aversion is innate or learnt. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig have recently discovered that it is hereditary: Even babies feel stressed when seeing these creatures - long before they could have learnt this reaction.

Early data shows nearly 2x prolonged median survival for inoperable pancreatic cancer

Mié, 10/18/2017 - 22:00
A retrospective review of 42 inoperable, locally-advanced pancreatic cancer patients treated at four institutions found that higher delivered radiation doses enabled via ViewRay's MRIdian adaptive MR-guided radiation therapy showed a near doubling of median overall survival (27.8 months compared to 14.8 months) and resulted in favorably lower toxicities (0 percent compared to 15.8 percent grade 3 or higher toxicity).

Too many care practitioners guilty of applying traditional values to same-sex adoption

Mié, 10/18/2017 - 22:00
'...too many professionals involved in the adoption and fostering process are clinging on to traditional ideas of what constitutes a family...'

International patients increasingly seek in vitro fertilization treatment in US

Mié, 10/18/2017 - 22:00
A new study from the Georgia Institute of Technology and the US Centers for Disease Control and Prevention finds that the use of assisted reproductive technology (ART) in the US by non-US residents is growing. These 'reproductive tourists' are more likely, compared to Americans, to use egg donors and carriers and genetically screen early embryos.

Mié, 10/18/2017 - 22:00
It found that complementary and alternative medicine is being used in connection with various health problems, particularly in situations where help provided by conventional medicine is considered inadequate.

Researchers 'drug the undruggable' through unique collaboration

Mié, 10/18/2017 - 22:00
A new study published in Nature, conducted by an alliance between industry and academia involving the University of Liverpool, highlights a new approach to targeting key cancer-linked proteins, thought to be 'undruggable'.

Six degrees of separation: Why it is a small world after all

Mié, 10/18/2017 - 22:00
This study examines how small-world networks occur within bigger and more complex structures.

An international consortium identifies the breast cancer patients who would benefit from a treatment

Mié, 10/18/2017 - 22:00
This new knowledge may be key to the early detection of patients who would benefit from zoledronic acid and those who should be spared, and it may accelerate the administration of the first preventive treatment of metastasis.
