Scientists offer an alternative way to understand and minimize health impacts from human-caused changes to the climate and environment.

If endangered primates disappear, so will their parasites. That's actually a problem

Posted: 23 Sep 2021 04:11 PM PDT

People are more aware of the plight of endangered gorillas than of gorillas' gut worms, and are understandably more enamored with mouse lemurs than their mites. Half of the world's roughly 500 primate species are at risk of extinction due to human activities such as hunting, trapping and deforestation. But the demise of the world's threatened primates could also trigger even more extinctions for the parasites that lurk within them, finds a new study.

Earliest evidence of human activity found in the Americas

Footprints at White Sands National Park in New Mexico confirm human presence over at least two millennia, with the oldest tracks dating back 23,000 years.

More support needed for pollination services in agriculture

Posted: 23 Sep 2021 10:26 AM PDT

The global decline of pollinators threatens the reproductive success of 90 per cent of all wild plants globally and the yield of 85 per cent of the world's most important crops. Pollinators -- mainly bees and other insects -- contribute to 35 per cent of the world's food production. The service provided by pollinators is particularly important for securing food produced by the more than two billion small farmers worldwide. An agroecologist points out that yields could be increased if pollinators were encouraged.

Carbon dioxide reactor makes 'Martian fuel'

Engineers are developing new ways to convert greenhouse gases to fuel to address climate change and get astronauts home from Mars.

Engineers introduce a new approach for recycling plastics

Posted: 23 Sep 2021 09:24 AM PDT

Engineers have come up with a revolutionary new method for tackling plastic pollution by harnessing the inner workings of proteins. The result? A whole new way of looking at plastic recycling.

New York waters may be an important, additional feeding area for large whales

Posted: 23 Sep 2021 08:56 AM PDT

A new study finds that that some large whale species (humpback, fin and minke whales) use the waters off New York and New Jersey as a supplemental feeding area feasting on two different types of prey species.

Intensified water cycle slows down global warming

Posted: 23 Sep 2021 08:56 AM PDT

A new study shows that the intensification of global hydrological cycle drives more ocean heat uptake into the deep ocean and moderates the pace of global warming.

A new method for removing lead from drinking water

Posted: 23 Sep 2021 08:56 AM PDT

Engineers designed a relatively low-cost, energy-efficient approach to treating water contaminated with heavy metals such as lead.

New online tool to help residents reduce the impact of traffic-related air pollution

Posted: 23 Sep 2021 07:21 AM PDT

Researchers have released a new online tool to help schools, hospitals and residents understand and reduce the impact of traffic-related air pollution.

Artificial intelligence may be set to reveal climate-change tipping points

Posted: 23 Sep 2021 05:29 AM PDT

Researchers are developing artificial intelligence that could assess climate change tipping points. The deep learning algorithm could act as an early warning system against runaway climate change.

Desert teamwork explains global pattern of co-operation in birds

A new study from the Kalahari Desert finds that teamwork allows birds to cope with brutally unpredictable environments.

Researchers mimic how water and wind create complex shapes in nature

Posted: 22 Sep 2021 11:32 AM PDT

Researchers have found a way to mimic the natural processes that create complex shapes and landscapes with the help of a vibrating plate and resulting energy fields.

Continental growth is not a continuous process

Posted: 22 Sep 2021 11:32 AM PDT

The continents, a specific feature of our planet, still hold many secrets. Using chemical data on sedimentary rocks compiled from the scientific literature from the 1980s to the present day, researchers have uncovered a new geological history of the continents. The research shows that their growth was not a continuous process, and that they have always been rich in silica1. This new study calls into question certain models of the onset of plate tectonics and provides us with a better understanding of continental growth through time.
