In their efforts to pick up the disease as early as possible, scientists are searching far and wide through the human body for tell tale signs of Alzheimer’s. A team from the Washington University School of Medicine in St. Louis has come up with a technique it says can detect one of these biomarkers in cerebrospinal fluid, which could lead to earlier diagnoses and more effective treatments.

New electrolyzer could make hydrogen and oxygen out of salty Mars water

Posted on by

Weight is a premium on space launches, so the less we have to take with us, the better. Now, engineers at Washington University in St. Louis have developed a new electrolysis device that may be able to convert very salty Martian water into breathable o… Continue reading New electrolyzer could make hydrogen and oxygen out of salty Mars water→

Earth’s water may have come from meteorites closer to home

Posted on by

A new study by the Centre de Recherches Pétrographiques et Géochimiques (CRPG, CNRS/Université de Lorraine) in Nancy, France, suggests that Earth’s water may have come from stony meteorites present in the inner solar system rather than comets or ast… Continue reading Earth’s water may have come from meteorites closer to home→

Cyborg locusts sniff out a career in detecting explosives

Posted on by

In the near(ish) future we could be using cyborg locusts as sniffer dogs to detect explosives, according to a new proof of concept study. A team showed that locusts could smell different amounts of explosive chemicals in the air to track the location o… Continue reading Cyborg locusts sniff out a career in detecting explosives→

Antibody aids immunotherapy in clearing out cancer in mice

Immunotherapy is a promising form of treatment against cancer that can have incredible results – when it works. Now researchers at Washington University in St. Louis have found that blocking a certain protein boosts the effectiveness of standard immuno… Continue reading Antibody aids immunotherapy in clearing out cancer in mice→

Smart bricks store energy in the walls themselves

Posted on by

Boring old bricks might not seem like something that can really be made high-tech, but researchers keep proving us wrong. Now, a team has found a way to turn bricks into energy storage devices, using them to power a green LED in a proof of concept stud… Continue reading Smart bricks store energy in the walls themselves→

Experimental gene therapy prevents obesity, builds muscle, without exercise or dieting

Posted on by

A compelling new study, led by scientists from Washington University School of Medicine in St. Louis, has found a novel gene therapy can prevent obesity and build muscle without the need for additional exercise, in mice being fed a high-fat diet.Contin… Continue reading Experimental gene therapy prevents obesity, builds muscle, without exercise or dieting→

Deleting immune cell genes prevents obesity in mice on high-fat diet

Posted on by

Being able to eat whatever we want and still stay slim is many people’s dream come true. And while it still remains firmly in fantasy territory for now, new research may have brought it a step closer to reality. By blocking a gene in certain immune cel… Continue reading Deleting immune cell genes prevents obesity in mice on high-fat diet→

Mice with diabetes “functionally cured” using new stem cell therapy

Posted on by

Diabetes is characterized by trouble producing or managing insulin, and one emerging treatment involves converting stem cells into beta cells that secrete the hormone. Now, scientists have developed a more efficient method of doing just that, and found… Continue reading Mice with diabetes “functionally cured” using new stem cell therapy→
