| Making sense of scents: Mice can identify specific odors amid complex olfactory environments Posted: 03 Aug 2014 04:37 PM PDT Exactly how animals separate the smells of objects of interest, such as food sources or the scent of predators, from background information has remained largely unknown. Even the extent to which animals can make such distinctions, and how differences between scents might affect the process were largely a mystery -- until now.       |
| Atlantic warming turbocharges Pacific trade winds Posted: 03 Aug 2014 04:36 PM PDT Rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. This has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific and has slowed the rise of global average surface temperatures since 2001.  |
| Self-assembling anti-cancer molecules created in minutes: Like a self-assembling 'Lego Death Star' Posted: 03 Aug 2014 04:35 PM PDT Researchers have developed a simple and versatile method for making artificial anti-cancer molecules that mimic the properties of one of the body's natural defense systems. The chemists have been able to produce molecules that have a similar structure to peptides which are naturally produced in the body to fight cancer and infection.  |
| New trick for 'old' drug brings hope for pancreatic cancer patients Posted: 03 Aug 2014 04:35 PM PDT Scientists have found a new use for an old drug by showing that it shrinks a particular type of pancreatic cancer tumor and stops it spreading.  |
| New genetic risk markers in pancreatic cancer Posted: 03 Aug 2014 04:31 PM PDT A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease.  |
| Fault trumps gruesome evidence when it comes to punishment Posted: 03 Aug 2014 04:31 PM PDT Issues of crime and punishment, vengeance and justice date back to the dawn of human history, but it is only in the last few years that scientists have begun exploring the basic nature of the complex neural processes in the brain that underlie these fundamental behaviors. A new brain imaging study has identified the mechanisms involved in balancing blameworthiness and the emotion-driven urge to punish.  |
| Posted: 03 Aug 2014 04:31 PM PDT Although mutations in a gene dubbed "the guardian of the genome" are widely recognized as being associated with more aggressive forms of cancer, researchers have found evidence suggesting that the deleterious health effects of the mutated gene may in large part be due to other genetic abnormalities, at least in squamous cell head and neck cancers.  |
| Electronic reminders can help patients prevent surgical site infections Posted: 01 Aug 2014 02:09 PM PDT The use of electronic reminders such as text messages, emails or voicemails is highly effective at getting surgical patients to adhere to a preadmission antiseptic showering regimen known to help reduce risk of surgical site infections, according to a first-of-its-kind study.  |
| Algorithm reduces use of CT scans when diagnosing children with appendicitis Posted: 31 Jul 2014 01:00 PM PDT Implementation of an algorithm aimed to diagnose pediatric patients with suspected appendicitis reduces the utilization of computed tomography scans, without affecting diagnostic accuracy, researchers have found.  |
