As a growing population and climate change threaten food security, researchers around the world are working to overcome the challenges that threaten the dietary needs of humans and livestock. A pair of scientists is now making the case that the knowledge and tools exist to facilitate the next agricultural revolution we so desperately need.
North America has lost nearly three billion birds since 1970, according to a new report, which also details widespread population declines among hundreds of North American bird species, including those once considered abundant. The results signal a long-developing yet largely overlooked biodiversity crisis occurring in avifaunal habitats across North America. Human impacts have contributed to an increase in global extinctions.
Limiting warming to 1.5° Celsius rather than 2.0° Celsius would maintain significant proportions of systems such as Arctic summer sea ice, forests and coral reefs and have clear benefits for human health and economies, say Ove Hoegh-Guldberg and colleagues in this Review. Their Review expands upon a 2018 special report by the Intergovernmental Panel on Climate Change focused on the effects associated with climate warming to 1.5° Celsius (C) above pre-industrial levels.

When a series of large mammal species began going extinct roughly 12,000 years ago, many surviving species began going their separate ways, says new research led by Macquarie University and the University of Nebraska-Lincoln.
World leaders need to urgently accelerate efforts to prevent "profound, if not catastrophic" climate change in future, a distinguished group of scientists has warned.
According to their new study published in Science today, acting to reduce climate change would cost much less than repairing the damage it would inflict in coming decades on people, infrastructure and ecosystems.
NASA's Aqua Satellite provided data on Major Hurricane Humberto that revealed its structure was changing as it was moving through the North Atlantic Ocean and past Bermuda.
On Sept. 18 at 12:30 p.m. EDT, the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite provided visible data on Humberto and measured clouds heights and temperatures that indicated a shift in the storm.
As a fighter jet quickly ascends and accelerates forward, a sonic boom reverberates across the jet's surface and through the surrounding sound waves. At best, it's unpleasant noise pollution. At worst, it can damage the surface of the aircraft. Dissipating this shock wave presents a tough challenge as traditional methods tend to offer efficiency or precision, but not both.
A protective protein that can detect newly-made incomplete and hence potentially toxic protein chains in higher cells is found to have a relative in bacteria. There, the protein also plays a central role in quality control which ensures that defective proteins are degraded. The functional mechanism of these evolutionarily related Rqc2 proteins thus acts as key quality control component and must therefore have already existed several billion years ago in the so-called last universal common ancestor.
An international team of researchers led by scientists at Princeton University has found that a magnetic material at room temperature enables electrons to behave counterintuitively, acting collectively rather than as individuals. Their collective behavior mimics massless particles and anti-particles that coexist in an unexpected way and together form an exotic loop-like structure.
The study was published this week in the journal Science.
Northeastern Texas has borne the brunt of Tropical Depression Imelda's heavy rainfall and NASA estimated that rainfall with an algorithm that incorporates data from satellites and observations.
Is your kid obsessed with video games and hanging out with questionable friends? These are common traits for involvement in cybercrime, among other delinquencies. New research from Michigan State University identified characteristics and gender-specific behaviors in kids that could lead them to become juvenile hackers.

In a current paper published in the journal "Nature", Heidelberg-based researchers and physicians describe how neurons in the brain establish contact with aggressive glioblastomas and thus promote tumor growth / New tumor activation mechanism provides starting points for clinical trials
Satellite imagery from NASA-NOAA's Suomi NPP satellite showed Tropical Storm Kiko maintained its shape and strength after weakening from hurricane-force.
The New York Times makes a concerted effort to drive home the point that climate change is real, but it does a poor job of presenting the basic facts about climate change that could convince skeptics, according to a review of the paper's coverage since 1980.
Imagery from NASA-NOAA's Suomi NPP satellite found Tropical Storm Lorena lashing the western coast of Mexico.
