Endangered California condors have been the poster birds for calls to get lead ammunition out of our environment, but they might have to make some room for our nation’s most iconic raptors thanks to a new study showing how lead ammunition is also harming bald eagles. It might be illegal to hunt bald eagles, but a study conducted by the U.S. Fish and Wildlife Service investigating the link between lead ammunition and bald eagle deaths in the Upper Mississippi River U.S. Fish and Wildlife Refuge.

‘Our Ocean’ 2014 brought together leaders from business, government and academic institutions, and NGOs from over 80 countries to discuss how economic development and ocean conservation can be reconciled. The oceans are extremely important for humans, generating more than 50 percent of the oxygen we breathe, absorbing excess carbon dioxide, and providing a source of food and income for millions of people worldwide.

We get a little suspicious when we hear the claims that it’s possible to get rid of the gunk that accumulates in our cells by doing a cleanse with “clean” foods. But what if some foods actually do help detox the body? The results of a recent clinical trial suggest that compounds in cruciferous vegetables like broccoli (and kale) prod cells to get rid of certain air pollutants. The intriguing randomized control trial of about 300 Chinese adults found that consuming a beverage made with broccoli sprouts every day for three months lead to high rates of excretion (in urine) of two harmful chemicals: benzene and acrolein.

The fine craftsmanship of a spider’s web helps these eight-legged arachnids catch their prey. But these silk-threaded designs can tell a spider a lot more than what they will be having for dinner. The spider that sits in the middle of its web monitors the silk threads for vibrations. And according to a new discovery by researchers at the Universities of Oxford, Strathclyde, and Sheffield the frequencies of these vibrations carry specific information about the prey, mates, and even the structural integrity of the web.

Oxford University neuroscientists have shown that fruit flies take longer to make more difficult decisions. In experiments asking fruit flies to distinguish between ever closer concentrations of an odour, the researchers found that the flies don’t act instinctively or impulsively. Instead they appear to accumulate information before committing to a choice. Gathering information before making a decision has been considered a sign of higher intelligence, like that shown by primates and humans.

Remember the Concorde? The supersonic passenger jet that flew from 1969 to almost 2000. It was not cost effective for the airlines, and extravagantly expensive for passengers. It was also cramped. The luxury was being able to fly from New York to London in about 3 hours! The Concorde had a big problem, the sonic boom it created when flying at supersonic speed. This led to governments restricting where it could fly supersonically and was a major factor in it not being economical to continue flying. That and a very advanced airframe that was getting old. The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA aeronautics researchers will present their work in Atlanta this week at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are making in overcoming some of the biggest hurdles to supersonic passenger travel.

The Antarctic shore is a place of huge contrasts, as quiet, dark, and frozen winters give way to bright, clear waters, thick with algae and peppered with drifting icebergs in summer. But as the planet has warmed in the last two decades, massive losses of sea ice in winter have left icebergs free to roam for most of the year. As a result, say researchers reporting in the Cell Press journal Current Biology on June 16, boulders on the shallow seabed — once encrusted with a rich assemblage of species in intense competition for limited space — now mostly support a single species. The climate-linked increase in iceberg activity has left all other species so rare as to be almost irrelevant. “The Antarctic Peninsula can be considered an early warning system — like a canary in a coal mine,” says David Barnes of the British Antarctic Survey. “Physical changes there are amongst the most extreme and the biology considered quite sensitive, so it was always likely to be a good place to observe impacts of climate change — but impacts elsewhere are likely to be not too far behind. A lot of the planet depends on the near-shore environment, not least for food; what happens there to make it less stable is important.”

A clinical trial involving nearly 300 men and women residing in one of China’s most polluted regions found that daily consumption of a half cup of broccoli sprout beverage produced rapid, significant and sustained higher levels of excretion of benzene, a known human carcinogen, and acrolein, a lung irritant.

You could say that, at least until now, cars and tomatoes have basically nothing in common. Tomatoes go from green to red as they ripen, and cars, well, they seem to be getting greener. As part of this trend, Ford is one of several companies that have been pursuing a viable bio-based plastic that could substitute for the petroleum-based plastics that dominate the industry today. Indeed, as cars continue to reduce vehicle weight in order to improve fuel economy, the use of plastics is becoming ever more common.

A new study by researchers at the University of Bristol and Plymouth Marine Laboratory has shed light on how different species of marine organisms are reacting to ocean acidification. Since the Industrial Revolution, nearly 30 per cent of all the carbon dioxide produced by manmade emissions has been absorbed by the ocean, causing a drop in pH of ocean surface waters: ocean acidification.
