Researchers have harnessed triboelectric nanogenerators to improve the charging of molecules in a way that dramatically boosts the sensitivity of a widely-used chemical analysis technique.
New study reveals characteristic of islands of magnetic metals between vacuum gaps, displaying tunnelling electric current.
Ultralight web of silk nanofibers withstands load 4,000 times its weight.
The mode of packaging of the genomic DNA in the cell nucleus determines patterns of gene expression. Researchers have used DNA-based nano-tweezers to measure the forces between nucleosomes, the basic packing units of nuclear DNA.
A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.
(University of Maryland Center for Environmental Science) The winners of the Nutrient Sensor Challenge will be announced at a special awards session at the Association for the Sciences of Limnology & Oceanography Aquatic Sciences (ASLO) meeting in Honolulu, Hawaii, on Thursday, March 2, at 5:30 p.m. HAST. The Challenge aimed to accelerate the development, production, and use of affordable, reliable, and accurate nutrient sensors. These sensors will enable automated and high-resolution nutrient monitoring in aquatic environments ranging from freshwater lakes and streams to the coastal ocean.
(American Friends of Tel Aviv University) A new Tel Aviv University study sheds light on a unique biological model of arsenic detoxification. According to the new research, the Entotheonella bacterium that inhabits the Theonella swinhoei sponge is one of the only known cases of a bacterium protecting its host from metal poisoning.
(Wildlife Conservation Society) Through its Climate Adaptation Fund, Wildlife Conservation Society (WCS) today solicited proposals from nonprofit conservation organizations to explore and implement new methods for helping wildlife adapt to rapidly-shifting environmental conditions brought about by climate change.
(The Company of Biologists) Tuesday Feb. 28, 2017 is Rare Disease Day, and this year's slogan is 'With research, possibilities are limitless'. Disease Models & Mechanisms is marking the day by spotlighting a recent paper on a newly discovered deafness-dystonia syndrome documented in a family from Pakistan.
(University of Cincinnati Academic Health Center) A University of Cincinnati (UC) researcher who has developed an immunotherapy to help reverse cocaine addiction that's been successful in animal models says he hopes to have it in clinical trials in human volunteers within a year.
(University of Kent) The Passenger Pigeon, a species of pigeon that died out in the early years of the 20th century, could have been saved even after it was considered doomed to extinction.As a result of this research, conservationists now have a model to test for functional extinction -- defined as a total reproductive failure -- allowing them to question species' extinctions in the past, as well as those that may be heading towards extinction.
(University at Buffalo) Partly inspired by the dynamics of a flock of birds, engineers devised a computational method for drones to quickly record whether they are over water, oil or the edge of the spill. This simple information is shared with the other drones in the swarm, as opposed to sharing actual images or video, which would require too much bandwidth.
(University of Pittsburgh) Through a five-year, $500,000 CAREEER Award from the National Science Foundation, a civil and environmental engineering research group at the University of Pittsburgh's Swanson School of Engineering will be developing new DNA sequencing methods to directly measure viral loads in water and better indicate potential threats to human health.
(University at Buffalo) The skin cells of four adults with schizophrenia have provided an unprecedented 'window' into how the disease began while they were still in the womb, according to a recent paper in Schizophrenia Research.
(American Osteopathic Association) Results from a study published in The Journal of the American Osteopathic Association point to an urgent need for sunburn prevention among young adults, particularly those who have skin with higher melanin content. Researchers found a surprising correlation between reporting a red or painful sunburn lasting a day or more with being 18 to 29 years of age and not self-identifying as white.
(Morgridge Institute for Research) The mystery of what controls the range of developmental clocks in mammals -- from 22 months for an elephant to 12 days for a opossum -- may lie in the strict time-keeping of pluripotent stem cells for each unique species.
(Technical University of Munich (TUM)) The most prevalent method for obtaining images of clogged coronary vessels is coronary angiography. For some patients, however, the contrast agents used in this process can cause health problems. A team at the Technical University of Munich (TUM) has now demonstrated that the required quantity of these substances can be significantly reduced if monoenergetic X-rays from a miniature particle accelerator are used.
(European Society of Clinical Microbiology and Infectious Diseases) A new report by the World Health Organization lays out, for the first time, which antibiotic-resistant bacteria pose the greatest risk to global health and urgently need new effective treatments. The report was chaired by Prof. Evelina Tacconelli, executive committee member of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) in collaboration with the WHO and with input from several ESCMID experts.
(Mary Ann Liebert, Inc./Genetic Engineering News) Researchers have designed a 3-D-printed porous scaffold for use in reconstructing ruptured anterior cruciate ligaments (ACL) in the knee and engineered it to deliver a human bone-promoting protein over an extended period of time to improve bone regeneration.
(North Carolina State University) New research offers insights into how far and how fast cyborg cockroaches -- or biobots -- move when exploring new spaces. The work moves researchers closer to their goal of using biobots to explore collapsed buildings and other spaces in order to identify survivors.
