Griffith University researchers have found evidence that demonstrates Aboriginal people were the first to inhabit Australia, as reported in the prestigious Proceedings of the National Academy of Sciences journal this week.

The work refutes an earlier landmark study that claimed to recover DNA sequences from the oldest known Australian, Mungo Man.

The Neanderthal genome included harmful mutations that made the hominids around 40% less reproductively fit than modern humans, according to estimates published in the latest issue of the journal GENETICS. Non-African humans inherited some of this genetic burden when they interbred with Neanderthals, though much of it has been lost over time. The results suggest that these harmful gene variants continue to reduce the fitness of some populations today. The study also has implications for management of endangered species.

Alzheimer's disease (AD) is a devastating condition with no known effective treatment. The disease is characterized by memory loss as well as impaired locomotor ability, reasoning, and judgment. Emerging evidence suggests that the innate immune response plays a major role in the pathogenesis of AD.

Scientists at King's College London have developed a blood test that accurately and reliably predicts whether depressed patients will respond to common antidepressants, which could herald a new era of personalised treatment for people with depression.

Guided by this test, patients with blood inflammation above a certain threshold could be directed towards earlier access to more assertive antidepressant strategies, such as a combination of antidepressants, before their condition worsens.

Oxford, June 6, 2016 - Phosphorus is the biggest cause of water quality degradation worldwide, causing 'dead zones', toxic algal blooms, a loss of biodiversity and increased health risks for the plants, animals and humans that come in contact with polluted waters. This threatens the loss of economic and social benefits from freshwaters upon which society relies. In a series of studies published in a special issue of Water Research, leading scientists assess how geo-engineering in lakes can control phosphorus pollution.

Though the claims that acrylamide is dangerous seem to be more manufactured hype than science, that isn't stopping the free market from providing an alternative.

You might think microbreweries are novel and trendy. Okay, they may be trendy but they are not novel. An ancient microbrewery dating around 5,000 years old was recently unearthed in China at the archaeological site of Mijiaya. 

Analyzing the remnants of the grains used has even provided a recipe for ancient Chinese beer!

Alcoholic drinks have a long and complicated history. Indeed, long before humans even came on the scene, other animals were indulging in fruit that had naturally fermented.

While watching the Stanley Cup match on Saturday, the first period ended and legendary sportscaster Bob Costas appeared on the screen with the Lexus Intermission Report.It made me chuckle seeing an overt corporate placement because the day before, a blogger at the political website Mother Jones named Tom Philpott had asked me on Twitter what I thought of a new EPA paper on the herbicide atrazine.

Be interested to hear thoughts on EPA atrazine report from @HankCampbell and @JonEntine https://t.co/5XGVg0iR7V

With CERN's Large Hadron Collider slowly but steadily cranking up its instantaneous luminosity, expectations are rising on the results that CMS and ATLAS will present at the 2016 summer conferences, in particular ICHEP (which will take place in Chicago at the beginning of August). The data being collected will be used to draw some conclusions on the tentative signal of a diphoton resonance, as well as on the other 3-sigma effects seen by about 0.13 % of the searches carried out on previous data this far.

Anxiety may be a first world problem - and a young female one at that.

A review of reviews (so calibrate your expectations) in Brain and Behavior finds that women are almost twice as likely to experience anxiety as men, and people from Western Europe and North America are more likely to suffer from anxiety than people from other cultures.

Anxiety disorders are a non-specific blanket term for excessive worry, fear and a tendency to avoid potentially stressful situations including social gatherings. Pretend money estimates claim these disorders cost $42.3 million in the U.S. In the European Union, over 60 million people are affected by anxiety disorders in a given year, likely because of all that worry about cell phones, ugly fruit and GMOs.
