New antibacterials being developed to tackle MRSA superbug

...vision. FtsZ is not found in humans so targeting a unique protein like this should reduce the likelihood of side-effects in patients. Because of the novel mode of action of the new class of compounds, the levels of resistance in the bacterial population should be extremely low if a new drug was to emerge fr...

Global 'sunscreen' has likely thinned, report NASA scientists

...lite record of aerosols in the lower atmosphere, a unique set of global estimates funded by NASA. Scientists...nts, the Aerosol Polarimetry Sensor, will have the unique ability to measure globally the properties of natural and human-made aerosols to unprecedented level...

40,000-year-old skull shows both modern human and Neandertal traits

...h archaic traits retained from the Neandertals and unique combinations of traits resulting from the blending of previously divergent gene pools. "The ultimate resolution of these issues must await considerations of larger samples of European early modern humans and chronologically intervening specimens. ...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...t colors by varying their size, giving the beads a unique optical signature. Having different color beads al...the quantum dots to create a set of beads that are unique and can be distinguished from each other. It’s similar to bar-coding -- once you barcode the beads a...

Researchers discover new details about HIV-1 entry and infection

... colleagues in the McElrath laboratory developed a unique model system to study the precise mechanisms by which HIV-1 enters the lower reproductive tract of human females. The researchers separated and removed the outer lining of vaginal cells, which serves as the first barrier to the virus. The isolated pr...

New synthetic self-assembling macromolecules mimic nature

...e delivery systems." But more immediate, "These unique block copolymers can be instructive models in understanding the forces that lead to the dense packing of DNA when complexed with viruses and other polymers," he said. ...

Scientists discover a new risk factor for Alzheimer's

...an find additional genetic changes that are either unique or enriched in the individuals with Alzheimer's," said St George-Hyslop. "Then we'll have the actual genetic variations that lead to the disease." After linking SORL1 to late-onset Alzheimer's, the team investigated the gene's function. Using cell...

Eating less salt could prevent cardiovascular disease

...oblems based on randomised trial data. It provides unique evidence that lowering salt in the diet might prevent cardiovascular disease. ...

Researchers discover surprising drug that blocks malaria

...able to malaria. "We're working on developing a unique drug that would combine anti-malarial drugs with blood pressure medication. We think it has a high likelihood of success," Haldar said. The next step is human clinical trials. ...

Discovery of an HIV inhibitor in human blood points to new drug class

...fuse with and infect its host's immune cells. That unique underlying mechanism allowed the inhibitor to remain effective against viral strains that are resistant to other antiretroviral drugs, they found. "Our data support the possibility that VIRIP may contribute to controlling HIV-1 replication in infe...

UCLA/Toronto researchers unlock key to memory storage in brain

... The cage was outfitted with patterned walls and a unique smell. To visualize which brain cells stored the mouse's memories about the cage, the scientists tracked a genetic marker that reveals recent neuron activity. When the team examined the animals' amygdalas after the experiment, they found substa...

The origin of the brain lies in a worm

...ent CNS structures. The regions are defined by the unique combination of regulatory genes expressed, which endow every type of neuron with a specific molecular fingerprint. Comparing the molecular fingerpint of Platynereis nerve cells with what is known about vertebrates revealed surprising similarities. ...

Re-analysis of cigarettes confirms tobacco companies increased addictive nicotine 11 percent

... to human health. They suggest that MDPH amend its unique reporting requirements to include more information about cigarette and smokeless tobacco product design features that affect nicotine delivery - as well as testing of a sample of brands for the actual delivery of nicotine to the body. ...

Health Canada approves cold and flu medicine

...nses in several categories. Because COLD-fX® is a unique patented product, it was issued an NPN in the non-traditional category, which requires the highest level of scientific evidence. In contrast, claims with the term “traditional?are not based on scientific evidence and products in the "monograph" cate...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...ny infrared wavelengths. Nearly every molecule has unique optical properties at infrared wavelengths between three and 12 micrometers, and QCLs provide access to any wavelength in this region. "Because of this access and the fact that QPAS is almost immune to acoustic interference, we have potential for ...

Antibody signal may redirect inflammation to fuel cancer

...ogy" (3). Coussens stresses that because of the unique antibody makeup of each person, there is no evidence and no likelihood that periodic booster shots of the immunoglobulin antibody, or even blood transfusions from someone with precancerous tissue could trigger cancer progression in a recipient. ...

Using dental X-rays to detect osteoporosis

...emic Center for Dentistry Amsterdam have created a unique way of identifying patients at risk of osteoporosis by using ordinary dental x-rays. Professor Paul F. van der Stelt and his team developed the largely automated approach to detecting the disease during a three-year, EU-funded collaboration with the ...

Making mice with enhanced color vision

...Retinas of primates such as humans and monkeys are unique among mammals in that they have three visual receptors that absorb short (blue), medium (green) and long (red) wavelengths of light. Mice, like other mammals, only have two; one for short and one for medium wavelengths. In the study, the researc...

Gene hunters close in on Lou Gehrig’s disease

... Johns Hopkins scientists have newly identified 34 unique variations in the human genetic code among 276 unrelated subjects with ALS. The 34 so-called single nucleotide polymorphisms, or SNPs, represent good candidate genes predisposing people to the non-inherited form of the fatal neurodegenerative diseas...

Scripps Research study reveals new activation mechanism for pain sensing channel

...nd their binding is long-lasting." TRPA1 is not unique among proteins to be activated by cysteine modifying agents, the study noted. Another signaling protein known as Kelch-like ECH-associated protein 1 (KEAP1) is activated by many of the same compounds that activate TRPA1; KEAP1 is a sensor for oxidati...
