Researchers at The Australian National University (ANU) have delved into the world of online conspiracy theories, showing most of the people behind them are actually pretty ordinary.The study looked at eight years of content, sifting through more than two billion comments posted on Reddit, including everything posted to the subreddit r/conspiracy.

"It is becoming clear that an acid extracellular pH plays an essential role in cancer cell progression, invasiveness and resistance to therapy," explain Yuri Korchev and Yasufumi Takahashi at Nano Life Science Institute of Kanazawa University and Yanjun Zhang at Imperial College London and colleagues at collaborating institutions in the UK, China, Japan and Russia in a recent paper.
What The Study Did: Cell phones are mainstays of daily life. This observational study analyzed 20 years of data on people who went to emergency departments with head and neck injuries from cell phone use to estimate the number of injuries, learn what types of injuries there were, and understand how the injuries occurred, such as from distracted driving or walking.

A UConn School of Dental Medicine researcher used pregnancy to unlock a missing link between various species of mammals and cancer malignancy--fundamentally changing the way we look at cancer metastasis.
Kshitiz, assistant professor in the department of biomedical engineering - a shared department between the School of Dental Medicine, School of Medicine, and School of Engineering - and Gunter Wagner and Andre Levchenko at Yale University used evolutionary biology to draw the connection in the Nature Ecology & Evolution journal.
The carnival worker who tries to guess your age relies on aspects of your appearance, such as your posture and whether any wrinkles emanate from the corners of your eyes and lips. If the carny's guess is more than a few years off, you win a stuffed koala.
But a team of Stanford University School of Medicine scientists doesn't need to know how you look to guess your age. Instead, it watches a kind of physiological clock: the levels of 373 proteins circulating in your blood. If the clock is off, you don't win a plush toy. But you may find out important things about your health.
In the Nadym district of the Yamalo-Nenets Autonomous Okrug, there are so-called "blue lakes". Located in the north-taiga, they are interesting not only for their unusual bright blue color, but also for their peculiar cone hollow with a depth of up to 12 m, the chemical composition of ultra-fresh waters, and the almost complete absence of fish. The flora and fauna of anomalous lakes have not been studied yet, and geological research data is very limited.
December 4, 2019 -- A new study at Columbia University Mailman School of Public Health suggests there is a two-way relationship between bullying perpetration and mental health problems among youth in the U.S. Researchers report that bullying perpetration increased the risk of developing internalizing problems, and having internalizing problems increased the probability of bullying others.
(Boston) - In a new study, researchers at Boston Medical Center and Boston University have uncovered a new association between more restrictive alcohol policies and lower rates of cancer mortality.
While opioids are often prescribed to treat people with trauma-related pain, a new UCLA-led study suggests doctors should use caution before prescribing the drug to those they believe may experience severe stress in the future, in order to reduce the risk the patient will develop PTSD.
CHICAGO - Researchers studying the brain found that women taking oral contraceptives, commonly known as birth control pills, had significantly smaller hypothalamus volume, compared to women not taking the pill, according to a new study presented today at the annual meeting of the Radiological Society of North America (RSNA).
Located at the base of the brain above the pituitary gland, the hypothalamus produces hormones and helps regulate essential bodily functions including body temperature, mood, appetite, sex drive, sleep cycles and heart rate.
Just as our left hand is not superposable to our right hand, the mirror image of certain molecules cannot be overlapped onto it, even when turned or twisted. These two mirror images are referred to by chemists as enantiomers and the molecule is said to be chiral. Chirality, which is a word derived from the ancient Greek word for hand, is important since it is present in our daily lives. For example, the stereoisomers of a molecule - i.e.
New findings by a University of Houston psychology professor indicate that among firefighters, distress tolerance amplifies associations between posttraumatic stress disorder (PTSD) symptoms and alcohol use severity. In the world of psychology, distress tolerance is your actual or perceived ability to withstand emotional distress. It is surviving - and knowing you can survive - an emotional incident.
Materials scientists at the University of California, Riverside and The University of Texas at Austin have demonstrated that it is possible to achieve photon up-conversion, the emission of light with energy higher than the one that excites the material, when using carefully designed structures containing silicon nanocrystals and specialized organic molecules.
Menlo Park, Calif. -- Researchers at the Department of Energy's SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons with powerful X-ray laser bursts just 280 attoseconds, or billionths of a billionth of a second, long.
The technology, called X-ray laser-enhanced attosecond pulse generation (XLEAP), is a big advance that scientists have been working toward for years, and it paves the way for breakthrough studies of how electrons speeding around molecules initiate crucial processes in biology, chemistry, materials science and more.
An international team of researchers has identified key networks within the brain they say interact to increase the risk that an individual will think about - or attempt - suicide.
In an article published today in Molecular Psychiatry, the researchers say their review of existing literature highlights how little research has been done into one of the world's major killers, particularly among the most vulnerable groups.
