Devising the best treatment for a patient with cancer requires doctors to know something about the traits of the cancer from which the patient is suffering. But one of the greatest difficulties in treating cancer is that cancer cells are not all the same. Even within the same tumor, cancer cells can differ in their genetics, behavior, and susceptibility to chemotherapy drugs.
A new research study has found that Medicaid enrollees with behavioral health and other chronic conditions are less likely to be working part or full time than those without these conditions, making it less likely they will meet new or proposed work requirements for Medicaid that have been implemented or proposed in some states.
ORLANDO, Fla., March 31, 2019 -- Aiming a laser beam at an aircraft isn't a harmless prank: The sudden flash of bright light can incapacitate the pilot, risking the lives of passengers and crew. But because attacks can happen with different colored lasers, such as red, green or even blue, scientists have had a difficult time developing a single method to impede all wavelengths of laser light. Today, researchers report liquid crystals that could someday be incorporated into aircraft windshields to block any color of bright, focused light.
The beginning of the end started with violent shaking that raised giant waves in the waters of an inland sea in what is now North Dakota.
Then, tiny glass beads began to fall like birdshot from the heavens. The rain of glass was so heavy it may have set fire to much of the vegetation on land. In the water, fish struggled to breathe as the beads clogged their gills.
LAWRENCE -- A study to be published Monday in the Proceedings of the National Academy of Sciences offers a scientific first: a detailed snapshot of the terrible moments right after the Chicxulub impact -- the most cataclysmic event known to have befallen life on Earth.
A Columbia University study has found that adversity early in life is associated with increased gastrointestinal symptoms in children that may have an impact on the brain and behavior as they grow to maturity.
The study was published online March 28 in the journal Development and Psychopathology.
Paper-based diagnostic tests are cheap, convenient and biodegradable. However, their use is limited by conventional dyes - which are not bright enough to show trace amounts of analyte, are prone to fading, and can be environmentally toxic.
Low levels of oxygen in the womb - which can be caused by smoking or conditions such as pre-eclampsia - may cause problems with fertility later in life, a study carried out in rats suggests.
The research, led by scientists at the University of Cambridge, found that exposing fetuses to chronic hypoxia (low oxygen levels) during development led to them having advanced ageing of the ovaries and fewer eggs available.
WASHINGTON, D.C. March 28, 2019 -- While many advancements have been in improving its efficiency, the refrigerator still consumes considerable amounts of energy each year.
Researchers at Dana-Farber/Boston Children's Cancer and Blood Disorders Center and the University of Massachusetts Medical School have developed a strategy to treat two of the most common inherited blood diseases -- sickle cell disease and beta thalassemia -- applying CRISPR-Cas9 gene editing to patients' own blood stem cells. Described this week in Nature Medicine and in a January report in the journal Blood, their approach overcomes prior technical challenges, editing blood stem cells more efficiently than in the past.
Scientists at the Department of Energy's Oak Ridge National Laboratory are working to understand both the complex nature of uranium and the various oxide forms it can take during processing steps that might occur throughout the nuclear fuel cycle. An improved understanding of uranium oxides, which fuel the vast majority of the U.S nuclear power fleet, could lead to the development of improved fuels or waste storage materials.
A new technique developed by scientists at the Broad Institute of MIT and Harvard gives an unprecedented view of the cellular organization of tissues. Known as Slide-seq, the method uses genetic sequencing to draw detailed, three-dimensional maps of tissues, revealing not only what cell types are present, but where they are located and what they are doing.
Your chances of getting a nasty migraine increase following a spinal cord injury, thanks to a chemical messenger in the brain that spikes to toxic levels, past studies have suggested.
For treatment to get any better, researchers need to catch that split-second spike in action and closely follow its path of destruction.
As we go about our daily lives, we are constantly bombarded by a steady stream of sensory information. Take a typical morning routine for example- roused from sleep by a shrill alarm, the strong aroma of freshly brewed coffee, and the brake lights and traffic horns of rush hour. In the course of a single day, we experience thousands of different cues across all senses.
The cocktail of man-made chemicals that we are exposed to daily is a health risk which current regulations and risk assessment overlook. This is the conclusion of the EU Horizon 2020 EDC-MixRisk project that is now being presented.
