Are ladybugs being overtaken by wasps? An entomologist is investigating a type of wasp present in Quebec that forces ladybugs to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host.

Brain's fear center is equipped with built-in suffocation sensor

The portion of our brains that is responsible for registering fear and even panic has a built-in chemical sensor that is triggered by a primordial terror -- suffocation. A new article shows in studies of mice that the rise in acid levels in the brain upon breathing carbon dioxide triggers acid-sensing channels that evoke fear behavior.

Chemists get custom-designed microscopic particles to self-assemble in liquid crystal

Chemists and physicists have succeeded in getting custom-shaped particles to interact and assemble in a controlled way in a liquid crystal.

Tobacco smoke exposure before heart transplantation may increase the risk of transplant failure

Scientists provide the first direct evidence that cigarette smoke exposure prior to a heart transplant in either the donor, recipient, or both, accelerates the death of a transplanted heart.

Virtual streams created to help restore real ones

Researchers have developed a unique new computer model called the Virtual StreamLab, designed to help restore real streams to a healthier state. The Virtual StreamLab demonstrates the physics of natural water flows at an unprecedented level of detail and realism.

Biology, training and profit sharing make best traders

Researchers have identified a group of traders consistently able to outperform the market, even during the credit crisis. The study offers a rare glimpse into how biology, experience and compensation schemes work together to make a profitable and -- crucially -- a prudent risk taker.

Bioengineers succeed in producing plastics without the use of fossil fuels

Scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals, heralding the creation of environmentally conscious plastics.

Startled flies may provide insight into ADHD

It seems obvious that naturally waking up from sleep and being startled by something in the environment are two very different emotional states. However, the neuroscience that underlies these different forms of arousal has, for the most part, remained a mystery. Now, new research demonstrates that there are at least two completely separate and independent fo […]

Scientists watch as peptides control crystal growth with 'switches, throttles and brakes'

By producing some of the highest resolution images of peptides attaching to mineral surfaces, scientists have a deeper understanding how biomolecules manipulate the growth crystals. This research may lead to a new treatment for kidney stones using biomolecules.

Cutting greenhouse pollutants could directly save millions of lives worldwide

Six new international studies show that cutting greenhouse gases, in particular ozone and black carbon, can quickly save millions of lives worldwide in addition to slowing climate change.
