Relationship between low income and obesity is relatively new, says study

EurekAlert! - Lun, 12/10/2018 - 23:00
It's a fact: poverty and obesity are intimately connected. But this relationship is only about 30 years old, according to a new study coauthored by UT researchers and published in Palgrave Communications, an open-access, online journal.

Taking uncertainty out of cancer prognosis

EurekAlert! - Lun, 12/10/2018 - 23:00
An analysis of nearly 20,000 cancer patient histories and genetic data has revealed that knowing the genetic cause of a cancer does not help predict how deadly the disease will be. Instead, researchers from CSHL have discovered that copy number variations in specific gene sites are far more informative, providing new opportunities to improve prognosis.

Pitt chemical engineers develop new theory to build improved nanomaterials

EurekAlert! - Lun, 12/10/2018 - 23:00
Researchers from the University of Pittsburgh's Swanson School of Engineering have developed a new theory to better predict how nanoclusters will behave when a given metal is introduced to their structure. Their findings were featured on the cover of ACS Journal of Physical Chemistry Letters.

Researchers discover unique immune cell likely drives chronic inflammation

EurekAlert! - Lun, 12/10/2018 - 23:00
For the first time, researchers have identified that an immune cell subset called gamma delta T cells that may be causing and/or perpetuating the systemic inflammation found in normal aging in the general geriatric population and in HIV-infected people who are responding well to drugs (anti-retrovirals).

Yale chemists find a new tool for understanding enzymes -- Google

EurekAlert! - Lun, 12/10/2018 - 23:00
In a new study published online this week in the Proceedings of the National Academy of Sciences, chemistry professor Victor Batista and his colleagues used the Google algorithm PageRank to identify key amino acids in the regulation of a bacterial enzyme essential for most microorganisms.

How returning to a prior context briefly heightens memory recall

EurekAlert! - Lun, 12/10/2018 - 23:00
Returning to the context where a memory was formed temporarily brings back vivid details of the episode by increasing the electrical excitability of the engrams that store the memory in the brain, a new study in Neuron shows.

Did supernovae kill off large ocean animals at dawn of Pleistocene?

EurekAlert! - Lun, 12/10/2018 - 23:00
The effects of a supernova -- and possibly more than one -- on large ocean life like school-bus-sized Megalodon 2.6 million years ago are detailed in a paper just published in Astrobiology.

Number of dementia sufferers worldwide grew by 117 percent in 26 years

EurekAlert! - Lun, 12/10/2018 - 23:00
An international group of collaborating scientists that includes HSE Professor Vasily Vlasov has analyzed data from 195 countries on the spread of Alzheimer's disease and other dementia between 1990 and 2016. The results have been published in the journal The Lancet Neurology.

Hong Kong's waters benefit health and wellbeing

EurekAlert! - Lun, 12/10/2018 - 23:00
A ground-breaking study has revealed how spending time in and around Hong Kong's 'blue spaces' (harbours, coastlines and beaches) is linked to better health and wellbeing, especially for older adults.

The importins of anxiety

EurekAlert! - Lun, 12/10/2018 - 23:00
According to some estimates, up to one in three people around the world may experience severe anxiety in their lifetime. In a study described today in Cell Reports, researchers at the Weizmann Institute of Science have revealed a previously unknown mechanism underlying anxiety. Targeting this biochemical pathway may help develop new therapies for alleviating the symptoms of anxiety disorders.

Transformed: the plant whose sex life fascinated Charles Darwin

EurekAlert! - Lun, 12/10/2018 - 23:00
Researchers have genetically transformed the Common Primrose (Primula vulgaris) for the first time in a development that could shed light on one of the plant world's most renowned reproductive systems.

New study makes 52 million tree stories more accessible to science

EurekAlert! - Lun, 12/10/2018 - 23:00
The world's primary archive of tree ring data, which holds more than 52 million cost-free records spanning 8,000 years of history, has gotten a makeover by scientists from four countries committed to making science more accessible. The International Tree Ring Data Bank, developed in 1974 and populated by hundreds of contributing scientists and agencies, had only been used for a handful of studies at a global scale due to inconsistent data accessibility and formatting.

EurekAlert! - Lun, 12/10/2018 - 23:00
An initiative adopted by Lancaster University to embed physical activity into the training for medical students has been showcased at a national and international level.Movement for Movement is recognised as a UK best practice exemplar by the 2018 WHO Europe Physical Activity Fact Sheets and the 2018 WHO Europe Physical Activity in the Health Sector report.Physical inactivity is the 4th leading risk factor of global mortality.

Lithuanian scientists' approach to perovskite solar cells -- cheaper production and high efficiency

EurekAlert! - Lun, 12/10/2018 - 23:00
A team of chemists from Kaunas University of Technology (KTU), Lithuania together with physicists from Helmholtz Zentrum Berlin (HZB) science institute, Germany are offering novel approach for the selective layer formation in perovskite solar cells. The molecule, synthesised by the KTU chemists, assembles itself into a monolayer, which can cover a variety of surfaces and can function as a hole transporting material in a perovskite solar cell.
