Most of us have probably felt that lasting sense of anxiety or even pain after enduring some kind of accident or injury. Now, researchers have the first evidence in any animal that there may be a very good reason for that kind of heightened sensitivity—or at least there is in the battle of squid versus fish. Squid that behave with extra vigilance after experiencing even a minor injury are more likely to live to see another day, according to a report appearing in the Cell Press journal Current Biology on May 8.

Tumors shrank or disappeared and disease progression was temporarily halted in 15 children with advanced neuroblastoma enrolled in a safety study of an experimental antibody produced at St. Jude Children's Research Hospital. Four patients are still alive after more than two-and-a-half years and without additional treatment.
A new study, published today in the Journal of Health Psychology, found that patients who gained weight 18 months after taking Orlistat attributed their weight-loss failure either to the side effects which have prevented them from sticking to the medication or felt that the medication simply had not worked.
A low-carbohydrate diet, but not a low-fat diet, reduces inflammation in patients with type 2 diabetes, according to research at Linköping University in Sweden.
A majority of the UK general public perceive alcohol adverts to breach the Advertising Standards Authority's Broadcast Committee of Advertising Practice (BCAP) Code suggesting that the current regulatory system for UK television is inadequate, research from The University of Manchester shows.
Researchers surveyed 373 adults, aged 18-74 years, showing them one of seven adverts that had been broadcast in the previous month on leading commercial television channels.
Leesburg, VA, May 8, 2014—Prompt and accurate localization of the site of bleeding is critical for the management of patients with acute GI bleeding. Planar 99mTc-labeled RBC scintigraphy is sensitive for detection of acute gastrointestinal (GI) bleeding but its accuracy for localization of a bleeding source is arguable, particularly in patients with complex GI anatomy from prior surgeries.
People who use antipsychotic medication (such as clozapine or risperidone) to treat psychiatric illness are nearly half as likely to commit a violent crime compared to when they are not using such medication, according to new results published in The Lancet. The use of mood stabilising drugs (such as lithium or carbamazepine) is also associated with a reduced rate of violent crime, although the reduction is less pronounced, and only in patients with bipolar disorder.
WASHINGTON, May 7, 2014 — Yesterday's release of the third National Climate Assessment (NCA) should serve as a claxon call for policymakers and the general public to take action to address and mitigate the observable and documented adverse climate disruption impacts being observed in every region and key economic sector of the United States.
Leesburg, VA, May 7, 2014— Patients undergoing peritoneal dialysis catheter placement via fluoroscopy and ultrasound-guidance experienced significantly fewer complications at 1 year post-insertion than did patients whose catheters were placed laparoscopically.
The first of two study groups received catheters using fluoroscopy and ultrasound guidance under conscious sedation by interventional radiologists. In the second group, the catheters were inserted using laparoscopy under general anesthesia by surgeons.
Leesburg, VA, May 5, 2014—Misinformation and misunderstanding about the risks associated with ionizing radiation create heightened public concern and fear, and may result in avoidance of screening mammography that can detect early cancers.
Leesburg, VA, May 5, 2014—Breast tomosynthesis in the diagnostic workup for one- or two-view focal asymmetry detected at screening mammography resulted in less use of ultrasound, fewer biopsies, and higher positive predictive value for cancer than when diagnostic exams involved only 2D mammography, according to a study conducted at the University of Virginia.
"Tomosynthesis has been evaluated in screening populations and been shown to decrease recall rates," said researcher Brandi Nicholson, "but studies in the diagnostic setting are lacking."
Surprisingly, researchers found that visiting a specialist prior to melanoma diagnosis may reduce their risk of dying by 90 percent.
STANFORD, Calif. — New research could soon make it easier for people with type-1 diabetes to get a safe night's sleep, says a Stanford University School of Medicine scientist who led the study.
In a large trial conducted in patients' homes in the United States and Canada, scientists demonstrated that they could predict and prevent dangerously low overnight blood sugars in adolescents and adults with type-1 diabetes.
HUNTSVILLE, TX (5/7/14) -- Gang members are twice as likely to become both a victim and an offender of a crime than non-gang members, as single acts of violence often lead to retribution between gangs as a whole, according to a new study.
While flexible gadgets such as "electronic skin" and roll-up touch screens are moving ever closer to reality, their would-be power sources are either too wimpy or too stiff. But that's changing fast. Scientists have developed a new device that's far thinner than paper, can flex and bend, and store enough energy to provide critical back-up power for portable electronics. Their report appears in the Journal of the American Chemical Society.
