New research suggests that rare species of trees in rainforests may help safeguard biodiversity levels as the environment undergoes change.
In a finding that could have broad applications in optical devices, Brown University researchers have shown that they can transform incoherent light to almost fully coherent and vice versa.
The world's tropical forests are in 'a critical state' in which the extinction of rare tree species could be a tipping point, according to an international team of scientists who have developed an analytical method to map their biodiversity.
Since 1989, in 63 nature reserves in Germany the total biomass of flying insects has decreased by more than 75 percent. This decrease has long been suspected but has turned out to be more severe than previously thought. Ecologists from Radboud University together with German and English colleagues published these findings in the scientific journal PLOS ONE on Oct. 18.
Researchers have created engineered proteins that lowered body weight, bloodstream insulin, and cholesterol levels in obese mice, rats, and primates.
Extreme marine conditions like El Niño are associated with shorter food chain length in the California Current ecosystem, a new analysis reports. The finding counters previous evidence for long-term stability and ecosystem resilience in nitrogen cycling and food web structure off the
A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life.The research published in the journal Science Advances predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.
After mating for the first time, most females of an Australian jumping spider are unreceptive to courtship by other males, and this sexual inhibition is immediate and often lasts for the rest of their lives, according to a study published Oct. 18, 2017, in the open-access journal PLOS ONE by Vivian Mendez from Macquarie University, Australia, and colleagues.
The total flying insect biomass decreased by more than 75 percent over 27 years in protected areas, according to a study published Oct. 18, 2017, in the open-access journal PLOS ONE by Caspar Hallmann from Radboud University, The Netherlands, and colleagues.
New findings by a Harvard Medical School team suggest that palbociclib, a drug that is FDA-approved to treat advanced breast cancer, may be able to overcome vemurafenib resistance in PTC.
A study led by the University of Pennsylvania School of Nursing's Diane Spatz, Ph.D., RN-BC, FAAN, the Helen M. Shearer Term Professor of Nutrition, has found that delayed lactogenesis was more prevalent among women who were obese pre-pregnancy and that excessive gestational weight gain was also associated with a delay in lactogenesis II. The study has been published in the Journal of Human Lactation.
Interactions between species play a key role in shaping biodiversity. A team of researchers including members of UZH has now shown that the coevolution of species that are embedded in complex networks of interactions is not only influenced directly by their partners but also indirectly by other species. This slows down the ability of complex communities to adapt to environmental change. Rapid climate changes are therefore likely to increase species' risk of becoming extinct.
Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have mutualistic interactions with multiple partners, leading to complex networks of interacting species. In a new study, a group of ecologists and evolutionary biologists from five universities has attempted to understand how species coevolve within large webs of mutualistic species.
Using a novel two-particle measurement method, a group of researchers measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement. The result, published in Nature, shows that the magnetic moments of the proton and antiproton are tremendously close, meaning that so-called CPT asymmetry -- a key factor in the lack of antimatter -- must be very small if it exists at all.
Physicists in the BASE collaboration at the CERN research center have been able to measure the magnetic force of antiprotons with almost unbelievable precision.
Scientists have found that stem cells in the skin remember an injury, helping them close recurring wounds faster. The discovery could advance research and treatment of psoriasis and other inflammatory diseases.
New study finds 'messy' microscopic structures on petals of some flowers manipulate light to produce a blue colour effect that is easily seen by bee pollinators. Researchers say these petal grooves evolved independently multiple times across flowering plants, but produce the same result: a floral halo of blue-to-ultraviolet light.
The brain circuitry that controls innate, or instinctive, behaviors such as mating and fighting was thought to be genetically hardwired. Not so, neuroscientists now say.
Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study. The study also considered electrical charges that could develop as astronauts transit the surface on potential human missions to Phobos.
New University of Washington research finds that for a budget of roughly $1000, it is possible for someone to track your location and app use by purchasing and targeting mobile ads. The team hopes to raise industry awareness about the potential privacy threat.
