Well-wrapped feces allow lobsters to eat jellyfish stingers without injury

Thu, 25/08/2016 - 3:32pm
Lobsters eat jellyfish without harm from the venomous stingers due to a series of physical adaptations. Researchers examined lobster feces to discover that lobsters surround their servings of jellyfish in protective membranes that prevent the stingers from injecting their venom. The results are vial for aquaculture efforts to sustainably farm lobsters for diners around the world.

Sea temperature and the lunar cycle predict the arrival of jellyfish in Israel

Thu, 25/08/2016 - 2:23pm
Large swarms of jellyfish reach the coast of Israel when the sea temperature ranges between 28.2 and 30 degrees Celsius and during the full moon, according to a new study. The study reveals, for the first time, the link between sea temperature and the lunar cycle and the arrival of swarms of Jellyfish s along the coast of Israel.

Unexpected trove of gas discovered around larger stars

Thu, 25/08/2016 - 2:23pm
Astronomers using ALMA surveyed dozens of young stars -- some Sun-like and others approximately double that size -- and discovered that the larger variety have surprisingly rich reservoirs of carbon monoxide gas in their debris disks. In contrast, the lower-mass, Sun-like stars have debris disks that are virtually gas-free.

Western diet increases Alzheimer's risk

Thu, 25/08/2016 - 2:21pm
Globally, about 42 million people now have dementia, with Alzheimer’s disease as the most common type of dementia. Rates of Alzheimer’s disease are rising worldwide. The most important risk factors seem to be linked to diet, especially the consumption of meat, sweets, and high-fat dairy products that characterize a Western Diet. The evidence of these risk factors, which come from ecological and observational studies, also shows that fruits, vegetables, grains, low-fat dairy products, legumes, and fish are associated with reduced risk.

Fateful evolution: New study improves accuracy of cancer diagnosis

Thu, 25/08/2016 - 2:11pm
Researchers use evolutionary theory to make predictions about which Barrett's esophagus (BE) patients will go on to develop cancer. The results point the way toward more accurate medical assessments for patients with BE and the development of early-warning beacons of disease known as biomarkers.

Is prehospital stroke treatment associated with better outcomes?

Thu, 25/08/2016 - 2:11pm
When treating a patient with stroke, every minute counts. A specialized stroke ambulance allows physicians to start specific treatment, such as thrombolysis, at scene. A recent study investigated whether this earlier response time leads to an improved prognosis.

New strategy to fight mosquitoes in a more efficient and sustainable way

Thu, 25/08/2016 - 2:11pm
Mosquitoes continue to build resistance to existing pesticides. Research has now shown that the chemical substances emitted by one of the mosquito's natural enemies -- the backswimmer -- makes the biological pesticide Bti more deadly. These so-called predator cues also impair the mosquito's immune system. Scientists argue that a cocktail of biological pesticides and synthetic predator cues may become the future strategy for mosquito control.

Potentially deadly heart condition plagues family members around same age

Thu, 25/08/2016 - 12:51pm
People with a family member who had an aortic dissection—a spontaneous tear in one of the body’s main arteries—should take note of the age that family member was when the aortic dissection occurred. According to a new study, aortic dissections have the potential to run in families and often occur within 10 years of the same age.
