A new cancer vaccine platform works by enhancing the ability of the immune system to recognize cancer by leveraging anti-viral memories it already has - due to the COVID-19 pandemic, the worst outbreak of the last 70 years.
New computer visualization technology developed by the Harvard Initiative in Innovative Computing has helped astrophysicists understand that gravity plays a larger role than previously thought in deep space's vast, star-forming molecular clouds.The insight is being illustrated in Nature's online version through new three-dimensional Portable Document Format (PDF) technology that will allow readers to view the article's key graphics using free PDF software already commonly found on computers.
An extract from grape seeds forces laboratory leukemia cells to commit cell suicide, according to researchers from the University of Kentucky. They found that within 24 hours, 76 percent of leukemia cells had died after being exposed to the extract.The investigators, who report their findings in the January 1, 2009, issue of Clinical Cancer Research, a journal of the American Association for Cancer Research, also teased apart the cell signaling pathway associated with use of grape seed extract that led to cell death, or apoptosis. They found that the extract activates JNK, a protein that regulates the apoptotic pathway.
Antibiotics may be overprescribed in kids because of concern by helicopter parents and worries about malpractice lawsuits, but in at least one instance they are saving a lot of lives - as a preventive measure to patients in intensive care units (ICUs).This from a study involving nearly sixthousand Dutch patients in thirteen hospitals. Researchers at University Medical Center (UMC) Utrecht have published their findings in an article in The New England Journal of Medicine.
Researchers in Great Britain and the United States have imaged the first high definition imprints that dolphin sounds make in water. They consider it a real breakthrough in deciphering dolphin language.Certain sounds made by dolphins have long been suspected to represent language but the complexity of the sounds has made their analysis difficult. Previous techniques, using the spectrograph, display cetacean (dolphins, whales and porpoises) sounds only as graphs of frequency and amplitude.
Religious people have more self-control than non-religious counterparts, says a study by University of Miami professor of Psychology Michael McCullough and he says this is why religious people may be better at pursuing and achieving long-term goals and also might help explain why religious people tend to have lower rates of substance abuse, better school achievement, less delinquency, better health behaviors, less depression, and longer lives.
Using tiny gold particles and infrared light, researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion. Such a system could one day be used to provide more control when battling diseases commonly treated with more than one drug, according to the researchers.Delivery devices already exist that can release two drugs, but the timing of the release must be built into the device — it cannot be controlled from outside the body. The new system is controlled externally and theoretically could deliver up to three or four drugs. The new technique takes advantage of the fact that when gold nanoparticles are exposed to infrared light, they melt and release drug payloads attached to their surfaces.
While in some cases a child with ADHD cannot function without medication, there is growing concern about the health risks and side effects associated with the common ADHD medications, including mood swings, insomnia, tics, slowed growth and heart problems. In 2006 the FDA required manufacturers to place warning labels on ADHD medications, listing the potential serious health risks. These high risks and growing concerns are fueling parents' search for alternatives that may be safer for their kids.The Transcendental Meditation technique may be an effective and safe non-pharmaceutical aid for treating ADHD, according to a study published in Current Issues in Education.
Lockheed Martin rolled out a conventional takeoff and landing (CTOL) variant of the F-35 Lightning II fighter, called F-35AF-1, which joins three weight-optimized F-35B short takeoff/vertical landing variants currently undergoing testing. The aircraft are structurally identical to the F-35s that will be delivered to armed services beginning in 2010.The first F-35A, known as AA-1, has completed 69 flights, and has a production-representative external shape and internal systems. Unlike AF-1 and the other F-35 test aircraft, AA-1's internal structure was designed before a 2004 weight-savings program resulted in structural revisions to all three F-35 variants.
Researchers at The Ohio State University Comprehensive Cancer Center have discovered that a molecule implicated in leukemia and lung cancer is also important in muscle repair and in a muscle cancer that strikes mainly children. The study shows that immature muscle cells require the molecule, called miR-29, to become mature, and that the molecule is nearly missing in cells from rhabdomyosarcoma, a cancer caused by the proliferation of immature muscle cells. Cells from human rhabdomyosarcoma tumors showed levels of the molecule that were 10 percent or less of those in normal muscle cells. Artificially raising the level of the molecule in the cancer cells cut their growth by half and caused them to begin maturing, slowing down tumor growth.
America is slightly schizophrenic when it comes to weight. If you open a newspaper you can simultaneously read that the five skinny women left must need counselling and society is to blame for that but anorexia is genetic even though that gene seems to only be present in middle-class white girls, all while we are the fattest country in the world. It can be confusing to people outside the US and anyone with a clue.There is some practical advice that has resulted from 70 years of weight studies; people who consume fewer calories than they burn lose weight 100% of the time.
If you put 'genomics' on the end of a word, you can gain instant credibility, so it makes sense that someone would come up with 'nutrigenomics' and say they can make a diet that corresponds to your genetic profile.It's tough to know what they mean by 'genetic profile' though obviously some people have a different metabolism than other so they can eat more. A customized diet consisting of 'eat fewer calories' wouldn't seem to require genomics. But 'nutrigenomics', they say, is something better because it aims to identify the genetic factors that influence the body's response to diet and studies how the bioactive constituents of food affect gene expression.
In a recently conducted study, a multidisciplinary French-American research team reported that Neanderthal extinction was principally a result of competition with Cro-Magnon populations, rather than the consequences of climate change.
