Aerial photographs from the 1940s and 1950s are being used to probe the climate history of the Antarctic Peninsula.
Any moves to modify the concrete Los Angeles River, to return parts of it to a more natural setting or to capture water, must not compromise its flood-protection function, say scientists.
Astronauts on the International Space Station use a 3-D printer to make a wrench from instructions sent up in an email.
A Japanese stem cell scientist at the heart of a scandal over false claims and fabricated research has resigned.
Tracking data reveals that golden-winged warblers fled one day before the April 2014 US tornado outbreak, probably because they "heard it coming".
Nasa's Orbiting Carbon Observatory produces its first global maps of carbon dioxide in Earth's atmosphere.
Fish are filmed more than 8,000m down in the Mariana Trench - the deepest place on Earth.
Shrinking the bubbles generated by ships could counteract the impact of climate change, a study suggests.
An amateur fossil hunter has unearthed a 7ft skeleton of a carnivorous marine reptile on a beach in south Wales.
Fewer than half the target number of badgers were killed in this year's cull in Gloucestershire, Defra announces.

An atomically thin material may lead to the thinnest-ever imaging platform. Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices.
Researchers from the University of Southampton have revealed a breakthrough in optical fiber communications. They developed an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals. The research explores a radically new approach to the generation of spectrally-efficient advanced modulation format signals as required in modern optical communication systems.
The recovery of large carnivores in Europe is a great success for nature conservation. At one third of mainland Europe, at least one species of large carnivore is present, according to a new article. It is an excellent example that humans and carnivores can share the same landscape, say researchers.
Researchers have created a simple mathematical model based on optical measurements that explains the stunning colors of Yellowstone National Park’s hot springs and can visually recreate how they appeared years ago, before decades of tourists contaminated the pools with make-a-wish coins and other detritus.
A genetic pathway has been found that accounts for the extraordinary size of the human brain. The research team has identified a gene, KATNB1, as an essential component in a genetic pathway responsible for central nervous system development in humans and other animals.

This is an image of a breast tumor identified as Epi-Luminal B of poor prognosis.
Breast cancer is the most common in women. One in nine will suffer breast cancer over their lifetime. Progress in prevention and early detection, and the use of chemotherapy after surgery (adjuvant chemotherapy), have achieved significantly increase survival in this disease in the last ten years, but much remains to be done.

Using a gene-editing system originally developed to delete specific genes, MIT researchers have now shown that they can reliably turn on any gene of their choosing in living cells.


A scanning electron micrograph of methicillin-resistant Staphylococcus aureus (MRSA) magnified 2381x.
Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of hospital-acquired infections, with the largest burden of infections occurring in under-resourced hospitals. While genome sequencing has previously been applied in well-resourced clinical settings to track the spread of MRSA, transmission dynamics in settings with more limited infection control is unknown. In a study published online today in Genome Research, researchers used genome sequencing to understand the spread of MRSA in a resource-limited hospital with high transmission rates.


This is Dr Stephen Munro at the School of Anthropology and Archaeology at ANU.
An international team of scientists has discovered the earliest known engravings from human ancestors on a 400,000 year-old fossilised shell from Java.


Insect muscle cells are marked in red, cell nuclei (DNA) in blue and virus in green.
Insects can transmit viral diseases to humans. Therefore, understanding how insects cope with viral infection, and what immune mechanisms are triggered, can be important to stop diseases transmission. In a study published in this week's issue of the scientific journal PLOS Pathogens*, researchers from the Instituto Gulbenkian de Ciencia (IGC; Portugal) now show that the entry route of the virus changes how the insect host responds to it. Using the fruit flies as a model of study, they discovered an immune mechanism that is specifically effective when flies are infected through feeding.
