Landmark study implicates specific genes in schizophrenia

The largest ever genetic study of schizophrenia has identified large numbers of specific genes that could play important roles in the psychiatric disorder. A group of hundreds of researchers across 45 countries analysed DNA from 76,755 people with schizophrenia and 243,649 without it to better understand the genes and biological processes underpinning the condition. The new study found a much larger number of genetic links to schizophrenia than ever before, in 287 different regions of the genome, the human body's DNA blueprint.

Hubble probes extreme weather on ultra-hot Jupiters

Astronomers have discovered bloated Jupiter-sized worlds that are so precariously close to their parent star they are being roasted at seething temperatures above 3,000 degrees Fahrenheit. That's hot enough to vaporize most metals, including titanium. They have the hottest planetary atmospheres ever seen. Hubble astronomers are reporting on bizarre weather conditions on these sizzling worlds. It's raining vaporized rock on one planet, and another one has its upper atmosphere getting hotter rather than cooler because it is being 'sunburned' by intense ultraviolet (UV) radiation from its star.

Researchers rejuvenate mouse organs through cellular reprogramming

Scientists have observed signs of rejuvenation in the pancreas, liver, spleen, and blood of mice after applying one cycle of cell reprogramming. To achieve this, the researchers have characterized rejuvenation by studying molecular marks in the DNA, gene expression, and cell metabolism.

Tiny jumping genes fingered as culprit in rise of antibiotic resistance

Biomedical engineers believe they have discovered the physical mechanism that causes high doses of antibiotics to promote the spread of antibiotic resistance between bacteria. The culprit, they say, is an overabundance of 'jumping genes,' called transposons, that carry the genetic instructions for resistance from the cell's source code to plasmids that shuttle between cells.

The art of smell: Research suggests the brain processes smell both like a painting and a symphony

What happens when we smell a rose? How does our brain process the essence of its fragrance? Is it like a painting -- a snapshot of the flickering activity of cells -- captured in a moment in time? Or like a symphony, an evolving ensemble of different cells working together to capture the scent? New research suggests that our brain does both.

Increased heat and drought stunt tropical trees, a major carbon sink

For a long time, ecologists assumed tree rings to be absent in tropical trees because of a lack of temperature and rain fluctuations in the trees' environment. But in recent decades, the formation of growth rings has been proven for hundreds of tropical tree species, which are sensitive to drought and usually experience at least a month or two of slightly reduced rainfall every year.

Ozone may be heating the planet more than we realize

New research reveals ozone in the lower atmosphere in particular contributed to warming in the Southern Ocean - which absorbs much of the planet's excess heat - more than previously realized. The study shows that ozone is more than just a pollutant, but also may be playing a significant role in climate change.

Mercury has magnetic storms

An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere.

New study of how bacteria swim could help prevent the spread of disease and improve medical treatments

A research team studied how bacteria swim in complex fluids, providing insight into how the microorganisms move through different environments, such as their natural habitats or inside the human body.

Researchers find new strategy for preventing clogged arteries

Revving up a process that slows down as we age may protect against atherosclerosis, a major cause of heart attacks and strokes. Scientists have successfully minimized artery-narrowing plaque in mice that would otherwise develop those lesions. The researchers did so by boosting chaperone-mediated autophagy (CMA), a cellular housekeeping process.
