Wearable sensors that detect gas leaks Posted: 16 Apr 2021 12:50 PM PDT A research team has developed wearable gas sensors that display an instantaneous visual holographic alarm.

The future of particle accelerators is here Posted: 16 Apr 2021 12:50 PM PDT A new accelerator and detector will serve as a kind of camera, taking 3D images and movies of electrons colliding with polarized protons and ions. Like a CT scanner for atoms, the EIC will let scientists see how force-carrying gluon particles hold together quarks, the internal components of protons and neutrons. It will also offer insights into the spin of fundamental particles. Cutting-edge accelerators could collide with both energy consumption and our assumptions about the nature of matter.

Neural plasticity depends on this long noncoding RNA's journey from nucleus to synapse Posted: 16 Apr 2021 12:50 PM PDT A synaptically localized long noncoding RNA proves to be an important regulator of neural plasticity.

Study reveals how some antibodies can broadly neutralize ebolaviruses Posted: 16 Apr 2021 09:01 AM PDT Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses -- and now, scientists have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies.

Sunlight to solve the world's clean water crisis Posted: 16 Apr 2021 09:01 AM PDT Researchers have developed technology that could eliminate water stress for millions of people, including those living in many of the planet's most vulnerable and disadvantaged communities.

Thermoelectric material discovery sets stage for new forms of electric power in the future Posted: 16 Apr 2021 09:00 AM PDT Researchers have created a new and potentially paradigm-shifting high-performance thermoelectric compound. The team created a new hybrid compound in which the crystalline and amorphous sublattices are intertwined into a one-of-a-kind crystal-amorphic duality.

Alpine plants are losing their white 'protective coat' too early in spring Posted: 16 Apr 2021 09:00 AM PDT Snow cover in the Alps has been melting almost three days earlier per decade since the 1960s. This trend is temperature-related and cannot be compensated by heavier snowfall. By the end of the century, snow cover at 2,500 meters could disappear a month earlier than today, as simulations by environmental scientists at the University of Basel demonstrate.

Heart health of shift workers linked to body clock Posted: 16 Apr 2021 06:10 AM PDT Working hours that deviate from an individual's natural body clock are associated with greater cardiovascular risk, according to recent research.

New nanoscale device for spin technology Posted: 16 Apr 2021 06:10 AM PDT Spin waves could unlock the next generation of computer technology, a new component allows physicists to control them.

Can financial stress lead to physical pain in later years? Posted: 15 Apr 2021 02:07 PM PDT Financial stress can have an immediate impact on well-being, but can it lead to physical pain nearly 30 years later? The answer is yes, according to new research.

Engineers improve performance of high-temperature superconductor wires Posted: 15 Apr 2021 02:07 PM PDT Researchers have discovered a novel way to improve the performance of electrical wires used as high-temperature superconductors (HTS), findings that have the potential to power a new generation of particle accelerators.

Genetic ancestry versus race can provide specific, targeted insights to predict and treat many diseases Posted: 15 Apr 2021 11:28 AM PDT The complex patterns of genetic ancestry uncovered from genomic data in health care systems can provide valuable insights into both genetic and environmental factors underlying many common and rare diseases -- insights that are far more targeted and specific than those derived from traditional ethnic or racial labels like Hispanic or Black, according to researchers.

Treatment not always needed to prevent vision loss in patients with elevated eye pressure Posted: 15 Apr 2021 11:28 AM PDT The national Ocular Hypertension Treatment Study was designed to determine whether lowering elevated eye pressure in patients might prevent vision loss from glaucoma. Researchers recently completed follow-up studies on patients 20 years after the start of the original study and found that not all patients with elevated eye pressure need pressure-lowering treatment to prevent vision loss from glaucoma.

New benefits from anti-diabetic drug metformin Posted: 15 Apr 2021 11:28 AM PDT Researchers have found that the anti-diabetic drug metformin significantly prolongs the survival of mice in a model that simulates the pathology of non-diabetic chronic kidney disease (ND-CKD) by ameliorating pathological conditions like reduced kidney function, glomerular damage, inflammation and fibrosis. Metformin's mechanism is different from existing therapeutics which only treat symptoms, such as the blood pressure drug losartan, so researchers believe that a combination these medications at low dose will be highly beneficial.

Process simultaneously removes toxic metals and salt to produce clean water Posted: 15 Apr 2021 11:28 AM PDT Removing salt is only one step in creating clean water from ocean or brackish water. Toxic compounds, from metals to human-made carcinogens, must be removed by subsequent processing. Chemists have invented a technique to remove salt and toxic ions in one step. They create porous nanoparticles, PAFs, with added functional groups that selectively absorb ionic compounds, like metals, or neutral species, like boron, then add them to the polymer membranes used in electrodialysis.

New type of cell contributes to increased understanding of ALS Posted: 15 Apr 2021 11:26 AM PDT The causes of the serious muscle disease ALS still remain unknown. Now, researchers have examined a type of cell in the brain blood vessels that could explain the unpredictable disease origins and dynamics. The results indicate a hitherto unknown connection between the nervous and vascular systems. The study has potential implications for earlier diagnoses and future treatments.

Uncovering the secret of the hunger switch in the brain Posted: 15 Apr 2021 11:18 AM PDT Researchers have revealed the mechanism of action of the master switch for hunger in the brain: the melanocortin receptor 4, or MC4 receptor for short. They have also clarified how this switch is activated by setmelanotide (Imcivree), a drug recently approved for the treatment of severe obesity caused by certain genetic changes.
