Uncovering first molecular missteps that drive neurons in pathway leading to Alzheimer's disease
Researcher will report additional evidence indicating that the massive brain cell death of Alzheimer's disease is result of mature neurons mistakenly re-entering the cell cycle.

Pitt study: Lung lesions of TB variable, independent whether infection is active or latent
The lung lesions in an individual infected with tuberculosis are surprisingly variable and independent of each other, despite whether the patient has clinically active or latent disease, according to a new animal study led by researchers at the University of Pittsburgh School of Medicine.

Glucose: Potential new target for combating annual seasonal influenza
In lab cultures of mammalian cells, researchers showed that influenza A infection could be controlled by targeting viruses' dependence on cellular glucose.

Timing is everything in new nanotechnology for medicine, security and research
A team of researchers has created a way to control the length of time light from a luminescent nanocrystal lingers, adding a new dimension of time to color and brightness in optical detection technology.

Blocking tumor-associated macrophages decreased glioblastoma's growth & extended survival in mice
Experimental drug that targets macrophages, a type of immune cells, in microenvironment surrounding lethal brain tumor glioblastoma multiforme decreased cancer's growth and extended survival of lab mice with cancer.

Climate change will endanger caribou habitat, study says
A group of 21 researchers from two continents, including Marco Musiani of the University of Calgary, looked closely at the DNA of reindeer in Scandinavia and Asia as well as tundra and woodland caribou in North America to find out more about how their environments were affected in the past and will be influenced in the future by climate change.

Researchers split water into hydrogen, oxygen using light, nanoparticles
Researchers from the University of Houston have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy.

Nicotine drives cell invasion that contributes to plaque formation in coronary arteries
Research on human and rat vascular smooth muscle cells provides evidence of a link between nicotine and atherosclerosis, major cause of heart attacks.

Silencing signals sent by parasite could aid sleeping sickness fight
Insights into how the parasites that cause sleeping sickness are able to communicate with one another could help limit the spread of the infection.

Nanoscale friction: High energy losses in the vicinity of charge density waves
In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves.

Climate change threatens genetic diversity, future of world's caribou
Caribou in southern and eastern Canada may disappear from most of their current range in 60 years if climate change takes the toll on their habitat that scientists predict in a paper appearing online Dec.

Deep-sea corals record dramatic long-term shift in Pacific Ocean ecosystem
Long-lived deep-sea corals preserve evidence of a major shift in the open Pacific Ocean ecosystem since around 1850, according to a study by researchers at UC Santa Cruz.

World e-waste map reveals national volumes, international flows
The first 'E-Waste World Map' has been created by UN organizations, industry, governments, non-government and science organizations through their 'Solving the E-Waste Problem (StEP)' initiative.

Virus grows tube to insert DNA during infection then sheds it
Researchers have discovered a tube-shaped structure that forms temporarily in a certain type of virus to deliver its DNA during the infection process and then dissolves after its job is completed.

High-resolution 3-D imaging draws new picture of Golgi's whereabouts during cell division
Resolving a fundamental question in cell biology and showing off the powers of new high-resolution 3-D imaging, NIH scientists have discovered where the Golgi apparatus, which sorts newly synthesized proteins for transport inside and outside the cell, goes when it disassembles during cell division.

Celldance 2013 video awards, the 'Cell Oscars,' roll out tiny red carpet
Time-lapse movies of a cellular heaven and hell, a crane fly sperm cell undergoing cell division, and the early development of muscle cells were recognized with the top three awards in the American Society for Cell Biology's Celldance

Up to 1 in 4 female prisoners in England and Wales self-harm
As many as one in four women prisoners in England and Wales self-harm every year, and female prisoners are four times more likely to self-harm than male inmates, according to the largest ever study of self-harm in prisons, published in The Lancet.
