The onset of the Indian summer monsoon has been predicted three months ahead for the last 40 years with the highest precision up until today. The result indicates longer seasonal forecasts based on machine learning may be a way to mitigate the consequences of an erratic monsoon system under future global warming. Dr. Takahito Mitsui and Dr. Niklas Boers of the Potsdam Institute of Climate Impact Research (PIK Potsdam), Germany, published the results in Environmental Research Letters.
Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the climate system than anticipated. The work is part of the European TiPES project, coordinated by the University of Copenhagen, Denmark but was conducted by Professor Michael Ghil, Ecole Normale Supérieure, Paris, France and coauthours from The Royal Meteorological Institute of Belgium and Parthenope University of Naples, Italy.
Tipping could be imminent
PLYMOUTH MEETING, PA [July 6, 2021] -- New research in the June 2021 issue of JNCCN--Journal of the National Comprehensive Cancer Network assesses the quality of cancer care delivered through extended sites coordinated by some of the country's largest cancer centers. The study was developed to implement strategies for disseminating discoveries and expanding access to the highest quality cancer care as part of AACI's Network Care Initiative, established by former AACI President Stanton L. Gerson, MD, Director of the Case Comprehensive Cancer Center.
The braincase of crocodylians has a distinctive structure. Unlike evolutionary relatives (birds and squamates), in crocodylians, all braincase bones are rigidly fixed together and form an akinetic structure. In the process of evolution, this made it possible for animals to develop powerful jaws and stronger bite forces, thanks to which crocodylians could gnaw through the hard shell of crayfish and turtles and hunt fish and land animals, including dinosaurs. As a result, they have managed to fill the niche of predators and survive to the present day.
Synthetic biology offers a way to engineer cells to perform novel functions, such as glowing with fluorescent light when they detect a certain chemical. Usually, this is done by altering cells so they express genes that can be triggered by a certain input.
AMHERST, Mass. - City sprawl and road development is increasingly fragmenting the habitats that many plant and animal species need to survive. Ecologists have long known than sustainable development requires attention to ecological connectivity - the ability to keep plant and wildlife populations intact and healthy, typically by preserving large tracts of land or creating habitat corridors for animals. New research from the University of Massachusetts Amherst argues that it's not enough for ecological modelling to focus on the landscape.
Terence D. Capellini has been interested in how joints work for almost three decades. Part of it is due to personal experience, having sustained several joint injuries as a college ice hockey player and recently developing knee osteoarthritis. But the principal investigator of Harvard's Developmental and Evolutionary Genetics Lab has also seen the pain and limited mobility of loved ones who've received similar diagnoses and injuries.
University of California San Diego School of Medicine researchers have identified a possible link between inadequate exposure to ultraviolet-B (UVB) light from the sun and an increased risk of colorectal cancer, especially as people age.
Manufacturing - Powered by nature
A team of researchers at Oak Ridge National Laboratory demonstrated the ability to additively manufacture power poles from bioderived and recycled materials, which could more quickly restore electricity after natural disasters.
Using the Big Area Additive Manufacturing system, the team 3D printed a 55-foot pole designed as a closed cylindrical structure. They evaluated three different composite materials with glass fibers including cellulose ester, recycled polycarbonate and bamboo fiber reinforced polystyrene.
Researchers at Linköping University have developed a method that may lead to new types of displays based on structural colours. The discovery opens the way to cheap and energy-efficient colour displays and electronic labels. The study has been published in the scientific journal Advanced Materials.
The future of cod stocks in the North Sea and the Barents Sea may be much easier to predict than before. This is the result of an international research project led by the Helmholtz-Zentrum Hereon and its Institute of Coastal Systems - Analysis and Modeling. For the first time, the team has succeeded in predicting the development of stocks for ten years in advance, taking into account both changes due to climate and fishing.
For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.
Post-traumatic stress disorder (PTSD) rings a bell for many, due to its rampant references in pop culture, and more, importantly, its prevalence in today's society. It is only probable that this disorder, which develops after shocking or dangerous events, would unfortunately affect the lives of many people. Medical researchers have been hard at work trying to come up with solutions to combat this condition and its manifestations effectively. Unfortunately, the neurological mechanisms of PTSD aren't clear, and without knowing this exactly, trying to find a cure is a shot in the dark.
Cardiovascular drugs do not affect COVID-19 outcomes--such as disease severity, hospitalizations, or deaths--according to an analysis of all relevant studies published as of November 2020. The findings are published in the British Journal of Clinical Pharmacology.
Investigators included 429 studies in a qualitative analysis and 390 in a quantitative analysis.
The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to examine other ways to grapple with the issue of food waste disposal.
