Researchers have pushed back the first-known physical evidence of insect flower pollination to 99 million years ago, during the mid-Cretaceous period.

A new technique for continuously monitoring both the size and optical properties of individual airborne particles could offer a better way to monitor air pollution.
Scientists argue that public debate about the role of soil carbon in battling climate change is undermining the potential for policymakers to implement policies that build soil carbon for other environmental and agricultural benefits.
A new study shows that hurricanes have become more destructive since 1900, and the worst of them are more than 3 times as frequent now than 100 years ago. A new way of calculating the destruction unequivocally shows a climatic increase in the frequency of the most destructive hurricanes that routinely raise havoc on the North American south- and east coast.
Researchers revealed that many larval fish species from different ocean habitats are ingesting plastics in their preferred nursery habitat.
A new study used genetic analysis to reveal how two different strains of a single species of flesh-eating bacteria worked in concert to become more dangerous than either one strain alone. The work suggests that other difficult-to-treat infections may be polymicrobial and treating only one organism in a polymicrobial infection could be the cause of many secondary infections and chronic infections...
Invisible footprints hiding since the end of the last ice age -- and what lies beneath them -- have been discovered by researchers using a special type of radar in a novel way.
The implementation of the 2013 American College of Cardiology/American Heart Association Guideline on the Treatment of Blood Cholesterol has been linked to improved overall cholesterol levels for American adults, especially those on cholesterol lowering medications, according to a new study.
Preventive cardiology researchers believe that a new blood test for protein biomarkers could identify early stage heart disease in people.
Toddler speech delays and temper tantrums have long been assumed to be linked. Now, for the first time, a new, large-scale study supports that assumption with data.
The Nile's unchanging path has been a geologic mystery because long-lived rivers usually move over time. Researchers have cracked the case by linking the river's flow to the movement of rock in the Earth's deep mantle. In the course of their investigation, they found the age of the Nile to be 30 million years -- about six times as long as previously thought.
An international team of researchers have revealed for the first time that Amazon forests with the greatest evolutionary diversity are the most productive.
Chemical engineers have developed a new method for atomic layer deposition, a technique commonly used in high-quality microelectronics. The new method can be used in materials with larger surfaces much more cheaply than current approaches, while preserving quality and efficiency.
Researchers have shown for the first time that it is possible to print complete integrated circuits with more than 100 organic electrochemical transistors.
The storage of energy for long periods of time is subject to special challenges. A researcher proposes using a combination of Mountain Gravity Energy Storage (MGES) and hydropower as a solution for this issue.
Mitochondria burn oxygen and provide energy for the body. Cells lacking oxygen or nutrients have to change their energy supply quickly in order to keep growing. Scientists have now shown that mitochondria are reprogrammed under depleted oxygen and nutrients. Tumors of the pancreas may also use this reprogramming mechanism to keep growing despite reduced nutrient and oxygen levels. The researchers...
Scientists have developed a computational method to objectively measure the personality of mice living in a semi-natural, group environment.
A new study finds that neurons affected in Parkinson's disease can shut down without fully dying, allowing them to also switch off neighboring cells. The findings might give scientists a better understanding of how the condition wrecks havoc in the brain, as well as ideas for new treatments.
Every minute counts when it comes to predicting severe weather. Combing data from cutting-edge geostationary satellites and traditional weather radar created a path toward earlier, more accurate warnings, according to researchers who studied supercell thuderstorms in the Midwest.
New research tested how open monitoring meditation altered brain activity in a way that suggests increased error recognition.
A recent study demonstrates that boreal forests of the Northern Hemisphere are sources of the greenhouse gas nitrous oxide (N2O). The study provides new information on the significance of trees as sinks and sources of greenhouse gases, proving that forests have relevance not only in the absorption of carbon, but also as a source of other greenhouse gases.
The spread of infectious diseases such as Zika depends on many different factors. Researchers were able to generate reliable maps for the transmission risk of the Zika virus in South America.
Social media is a rich vein of data for researchers to discover important trends in human environmental behavior. But analyzing this staggering quantity of data is a major challenge -- until now.
A study on mice shows animal research may need to take into account the connection between genes, behavior and personality.
Researchers assessed how experience with dogs affects humans' ability to recognize dog emotions. Participants who grew up in a cultural context with a dog-friendly attitude were more proficient at recognizing dog emotions. This suggests that the ability to recognize dogs' expressions is learned through age and experience and is not an evolutionary adaptation.
