Scientists have made a major breakthrough in understanding how the parasite that causes malaria is able to multiply at such an alarming rate, which could be a vital clue in discovering how it has evolved, and how it can be stopped.
For the first time, scientists have shown how certain molecules play an essential role in the rapid reproduction of parasite cells, which cause this deadly disease.
This could be the next step towards being able to prevent the malaria parasite from reproducing.
Researchers from Australia, Singapore, Taiwan and the UK placed cardboard cut-out models of the golden orb-weaver, Nephila pilipes, onto real webs in the field. Testing different combinations of colours and patterns they discovered that both the yellow colour and the black and yellow mosaic pattern are essential for luring prey during the day.
The webs of Nephila pilipes also capture prey during the night, and the experiments demonstrated that the yellow colour alone was very effective at luring nocturnal insects.
In salt-sensitive hypertension, immune cells gather in the kidneys and shoot out free radicals, heightening blood pressure and damaging this pair of vital organs, scientists report.
These highly reactive chemicals, also called reactive oxygen species, or ROS, are a byproduct of our body's use of oxygen that our immune system uses to kill invaders. But at high levels, they also are known to alter key components of our body like proteins, and contribute to a myriad of diseases from hypertension to cancer.
CLEVELAND (Feb. 11, 2020)--Researchers from Case Western Reserve University School of Medicine, University Hospitals Cleveland Medical Center (UH), Cleveland Clinic and Lifebanc (a Northeast Ohio organ-procurement organization) have developed a new way to preserve donated kidneys--a method that could extend the number and quality of kidneys available for transplant, saving more people with end-stage renal disease, more commonly known as "kidney failure."
Maunakea, Hawaii - A team of astronomers led by Brendan Bowler of The University of Texas at Austin has probed the formation process of giant exoplanets and brown dwarfs, a class of objects that are more massive than giant planets, but not massive enough to ignite nuclear fusion in their cores to shine like true stars.
Wearable tech and electronic cloth may be the way of the future, but to get there the wiring needs to be strong, flexible and efficient.
Boron nitride nanotubes (BNNT), studied by physicists at Michigan Technological University, encase tellurium atomic chains like a straw, which could be controllable by light and pressure. In collaboration with researchers from Purdue University, Washington University and University of Texas at Dallas, the team published their findings in Nature Electronics this week.
How do some mammals postpone the development of their embryos to await better conditions for having offspring? A recent study at the UW Medicine Institute for Stem Cell and Regenerative Medicine explored this reproductive enigma, which can occur in more than 130 species of mammals as well as in some marsupials.
New Rochelle, NY, February 10, 2020--The dramatic shift in how nasal tip surgery is being performed given changes in the intended goals and evolving techniques is highlighted in a Special Communication by and interview with Dean Toriumi, MD, published in the Official Journal of the American Academy of Facial Plastic and Reconstructive Surgery, Facial Plastic Surgery & Aesthetic Medicine, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
Science now supports the saying, "happy wife, happy life." Michigan State University research found that those who are optimistic contribute to the health of their partners, staving off the risk factors leading to Alzheimer's disease, dementia and cognitive decline as they grow old together.
