Cosmic Yeti from the dawn of the universe found lurking in dust

Astronomers accidentally discovered the footprints of a monster galaxy in the early universe that has never been seen before. Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given ...

All-organic farming could increase UK emissions: study

An all-out shift to organic farming in England and Wales could lead to a net increase in Britain's greenhouse gas emissions as a drop in yields would lead to higher food imports, scientists estimated Tuesday.

Inflammation and autism—an important piece of the puzzle

Autism spectrum disorder has neither a distinct pathogenesis nor pharmaceutical treatment, yet evidence continues to mount demonstrating immune dysfunction and inflammation in specific brain regions of children diagnosed ...

A 'shocking' new way to treat infections

Titanium has many properties that make it a great choice for use in implants. Its low density, high stiffness, high biomechnanical strength-to-weight ratio, and corrosion resistance have led to its use in several types of ...

In Alzheimer's research, scientists reveal brain rhythm role

In the years since her lab discovered that exposing Alzheimer's disease model mice to light flickering at the frequency of a key brain rhythm could stem the disorder's pathology, MIT neuroscientist Li-Huei Tsai and her team ...

3-D printing, bioinks create implantable blood vessels

A biomimetic blood vessel was fabricated using a modified 3-D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result ...

Lead isotopes a new tool for tracking coal ash

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects.

Scientists unpack how taste neurons control food intake

Using the common fruit fly as a model, a research team led by scientists at the University of California, Riverside, studied how taste neurons control feeding behaviors and found that flies genetically modified to have only ...

A blood factor involved in weight loss and aging

Aging is a process that affects all functions of the human body, particularly brain function. However, aging can be delayed through lifestyle changes (physical exercise, restricting calorie intake, etc.). Researchers at the ...

NASA imagery reveals Neoguri now extra-tropical

Formerly a typhoon, now an extra-tropical storm, Neoguri has taken on more of a frontal system appearance in imagery from NASA's Aqua satellite. The final warning on the system has been issued.

Rethinking the role of technology in the classroom

Preparing elementary school students for active citizenship in an increasingly digital world requires introducing them to the latest technologies, but engaging those same kids in the classroom and involving their parents ...

Ants: Jam-free traffic champions

Whether they occur on holiday routes or the daily commute, traffic jams affect cars as well as pedestrians. Scientists at the Research Center on Animal Cognition (CNRS/Université Toulouse III—Paul Sabatier) and the University ...

Snap! How the camera took over the world

Photographs tell a story beyond words. They can entertain, scandalise, educate and generate emotion. Billions of images are produced worldwide every day yet little is often known about how or why they were produced and by ...

New rocket fairing design offers smoother quieter ride

Satellites are built to live in the harsh environment of space but engineers must also factor in the rigours of the journey there. ESA has helped RUAG Space Switzerland to develop new rocket fairings that offer a smoother ...

What is sex really for?

Few topics arouse as much interest and controversy as sex. This is hardly surprising. The biological continuance of the species hinges on it—if human beings stopped having sex, there would soon be no more human beings. ...

Halfway toward LHC consolidation

The Large Hadron Collider is such a huge and sophisticated machine that the slightest alteration requires an enormous amount of work. During the second long shutdown (LS2), teams are hard at work reinforcing the electrical ...
