Charged particles may be small, but they matter to astronauts. NASA's Human Research Program (HRP) is investigating these particles to solve one of its biggest challenges for a human journey to Mars: space radiation and its effects on the human body.
Scientists from the University of Surrey have developed a rapid and highly sensitive fingerprint test that can take just seconds to confirm whether someone has used cocaine.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a potential new tactic for rapidly determining whether an antibiotic combats a given infection, thus hastening effective medical treatment and limiting the development of drug-resistant bacteria. Their method can quickly sense mechanical fluctuations of bacterial cells and any changes induced by an antibiotic.
Chemists from Utah State University and Russia's Southern Federal University report a new, metastable, ultra-light crystalline form of aluminum has been computationally designed using density functional calculations with imposing periodic boundary conditions.
For years, medical investigators have tried and failed to develop vaccines for a type of staph bacteria associated with the deadly superbug MRSA. But a new study by Cedars-Sinai investigators shows how staph cells evade the body's immune system, offering a clearer picture of how a successful vaccine would work.
Halting the opioid epidemic requires aggressive action across multiple dimensions, including informed, active, and determined front-line leadership from health clinicians working in every setting throughout the nation, says a new National Academy of Medicine (NAM) special publication developed at the request of the National Governors Association to assist the nation's governors as they work with clinicians to counter the opioid crisis.
An MIT team has determined formulas to guide development of a promising new high-tech material, composed of insulating metal oxides known as alkaline-earth-metal binary oxides, that could lead to better computer memory chips, refrigeration systems, and other devices.
A new paper in the journal Astrobiology suggests NASA and others hunting for proof of Martian biology in the form of 'microfossils' could use the element vanadium in combination with Raman spectroscopy to confirm traces of extraterrestrial life.
Expanding the high-dose influenza vaccine recommendation to include middle-aged adults with chronic health conditions may make economic sense and save lives. The findings may justify for clinical trials of the high-dose and new recombinant trivalent influenza vaccines in 50- to 64-year-old adults with chronic illnesses, such as heart or lung disease, diabetes, or cancer, to determine if they do provide considerably better protection than the currently recommended standard dose quadrivalent vaccine.
Novel lithium electrodes coated with indium could be the basis for more powerful, longer-lasting, rechargeable batteries. The coating hinders undesirable side-reactions between the electrode and electrolyte, provide a more uniform deposition of lithium when charging, and augments storage in the lithium anode via alloying reactions between lithium and indium, as reported by American scientists in the journal Angewandte Chemie. Their success stems from the good diffusion of lithium ions along the interfacial layer.
