Muscles have circadian clocks that control exercise response
Humans may be able to respond better to exercise during the daytime, suggests new research. Oxygen and the internal clock "do a dance together" in muscle cells to make energy, they say. The discovery provides insights that could lead to optimizing muscle function.

Turning biofuel waste into wealth in a single step
Lignin is a bulky chain of molecules found in wood and is usually discarded during biofuel production. But in a new method to reduce our reliance on fossil fuels, the simple addition of formaldehyde could turn it into the main focus.

Scientists reveal link between cell metabolism and the spread of cancer
A crucial factor in the spread of cancer has been discovered by a team of researchers that has demonstrated that the metabolism of macrophages, a particular type of white blood cell, can be attuned to prevent the spread of cancer. The key is in making these macrophages more prone to ‘steal’ sugar from the cells forming the tumor’s blood vessels. As a result, these blood vessels will be structured more tightly, which can prevent cancer cells from spreading to other organs.

Jet lag treatment? Blast of thin air can reset circadian clocks
We might not think of our circadian clock until we are jetlagged, but scientists continue to puzzle over what drives our biological timepiece. Now, a study has found that variations in surrounding oxygen levels can reset circadian clocks of mice. If confirmed in humans, the research could help inform how airlines moderate cabin air pressure.

New perovskite solar cell design could outperform existing commercial technologies
A new design for solar cells that uses inexpensive, commonly available materials could rival and even outperform conventional cells made of silicon. In a new article, researchers describe using tin and other abundant elements to create novel forms of perovskite -- a photovoltaic crystalline material that's thinner, more flexible and easier to manufacture than silicon crystals.

Overlooked molecules could revolutionize our understanding of the immune system
Thousands of new immune system signals have been uncovered with potential implications for immunotherapy, autoimmune diseases and vaccine development. The researchers behind the finding say it is the biological equivalent of discovering a new continent.

Early fossil fish from China shows where our jaws came from
Where did our jaws come from? The question is more complicated than it seems, because not all jaws are the same. In a new article, palaeontologists from China and Sweden trace our jaws back to the extinct placoderms, armoured prehistoric fish that lived over 400 million years ago.

ADHD symptom persistence into adulthood estimated
Sixty percent of children with ADHD in a recent study demonstrated persistence of symptoms into their mid-20's, and 41 percent had both symptoms and impairment as young adults.

Liquid-repellant tape adheres to any surface
A superomniphobic tape has been created that, when adhered to any surface, gives the surface liquid-repelling properties. Superomniphobic surfaces are extremely repellent to all liquids, made possible by an air cushion that lies between a liquid and a solid surface.

Needle-sized imaging probe improves image quality, surgical outcome
To provide a better view of difficult to see tissue, researchers have miniaturized an imaging probe to fit inside a needle that can be inserted into the eye during eye surgery. The probe was used without complications in three human patients, as described in a new article.
