Although nitrogen is essential for all living organisms—it makes up 3% of the human body—and comprises 78% of Earth's atmosphere, it's almost ironically difficult for plants and natural systems to access it.
Zimbabwe's wildlife agency said Monday it would move hundreds of elephants and other animals in a dramatic bid to save them from a lethal drought.
Mini Mercury skipped across the vast, glaring face of the sun Monday in a rare celestial transit.
A moderate earthquake has been felt across Hawaii's Big Island, but there are no immediate reports of damage.
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. It is especially promising for analyzing fine particulate matter measuring less than 2.5 microns (PM2.5), which can reach deep into the lungs and cause health problems.
(CAPE CANAVERAL, Fla.) — Mini Mercury skipped across the vast, glaring face of the sun Monday in a rare celestial transit. Stargazers used solar-filtered binoculars and telescopes to spot Mercury — a tiny black dot — as it passed directly between Earth and the sun on Monday. The eastern U.S. and Canada got the whole 5 ½-hour show, weather permitting, along with Central...
There is growing interest in the potential for soil carbon to mitigate climate change, brought into the public sphere at the 2015 United Nations Climate Change Conference (COP21) in Paris. France. There, the French government launched an international initiative, "4per1000," aimed at reducing greenhouse gas emissions by building soil carbon.
Invisible footprints hiding since the end of the last ice age—and what lies beneath them—have been discovered by Cornell University researchers using a special type of radar in a novel way.
The most damaging tropical cyclones are three times more frequent now than they were 100 years ago.
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...
A loss of snow and ice cover are the main reasons for the reduction of the Arctic's albedo effect, not soot as had been previously thought.
A new study reveals that extremely damaging hurricanes are becoming more frequent relative to moderate storms, likely due to climate...
Infection found in patient who required quadruple amputation after developing rare conditionDoctors have discovered an aggressive flesh-eating infection that spreads around the body when two strains of microbe combine to overcome the host’s defences.The infection was found in a patient who required a quadruple amputation after they developed necrotising fasciitis, a rare bacterial condition that...
A Dartmouth study finds that artisanal-scale gold mining is altering water clarity and dynamics in the Madre de Dios River watershed in Peru, a tropical biodiversity hotspot. Higher levels of suspended sediment were found in rivers near the mining sites, with increasing impacts as mining has become more widespread in the past two decades. The elevated sediment levels contain mercury and other...
In recent years, scientists have found that serious infections that progress rapidly and resist treatment are often caused by multiple microbes interacting with one another. Very little is known about these so-called polymicrobial infections, but traditional diagnostic methods often misidentify them as monomicrobial, or single-microbe, infections.
Humans have evolved dynamic defense mechanisms against the viruses that seek to infect our bodies—proteins that specialize in identifying, capturing and destroying the genetic material that viruses try to sneak into our cells.
New research shows that many larval fish species from different ocean habitats are ingesting plastics in their preferred nursery habitat.
A new study co-led by researchers in the U.S. and China has pushed back the first-known physical evidence of insect flower pollination to 99 million years ago, during the mid-Cretaceous period.
A new study by researchers at the Niels Bohr Institute, University of Copenhagen, Aslak Grinsted, Peter Ditlevsen and Jens Hesselbjerg shows that hurricanes have become more destructive since 1900, and the worst of them are more than three times as frequent now than 100 years ago. A new way of calculating the destruction, compensating for the societal change in wealth, unequivocally shows a...
