A Reproducibility Crisis

Science Magazine:

More than 70% of researchers have tried and failed to reproduce another scientist’s experiments, and more than half have failed to reproduce their own experiments. Those are some of the telling figures that emerged from Nature’s survey of 1,576 researchers who took a brief online questionnaire on reproducibility in research.

Epigenetics and Sexual Orientation

“Baby, I was born this way,” Lady Gaga sang in a 2011 hit that quickly became a gay anthem. Indeed, over the past 2 decades, researchers have turned up considerable evidence that homosexuality isn’t a lifestyle choice, but is rooted in a person’s biology and at least in part determined by genetics. Yet actual “gay genes” have been elusive.

A new study of male twins, scheduled for presentation at the annual meeting of the American Society of Human Genetics (ASHG) in Baltimore, Maryland, today, could help explain that paradox. It finds that epigenetic effects, chemical modifications of the human genome that alter gene activity without changing the DNA sequence, may have a major influence on sexual orientation.

But eight major studies of identical twins in Australia, the United States and Scandinavia during the last two decades all have arrived at the same conclusion: homosexuality primarily and overwhelmingly (90%) is an acquired disposition, instead of genetic. [emphasis in original]

Many Medications Less Effective Than Thought

Sir Richard Thompson, former-president of the Royal College of Physicians and personal doctor to the Queen for 21 years, warned tonight that many medicines are less effective than thought.

The physician is one of a group of six eminent doctors who today warn about the influence of pharmaceutical companies on drugs prescribing.

The experts, led by NHS cardiologist Dr Aseem Malhotra, claim that too often patients are given useless – and sometimes harmful – drugs that they do not need.

Failing Climate Models

The latest salvo in an ongoing row over global-warming trends claims that warming has indeed slowed down this century.

A group of scientists recently put out a new study confirming the 15-year “hiatus” in global warming. That study made headlines, but what went largely unnoticed was a major admission made by the paper’s authors: the climate models were wrong.

“There is this mismatch between what the climate models are producing and what the observations are showing,” John Fyfe, Canadian climate modeler and lead author of the new paper, told Nature. “We can’t ignore it.”

“When a theory contradicts the facts” you need to change the theory, climate scientist John Christy told Congress in January hearing. “The real world is not going along with rapid warming. The models need to go back to the drawing board.”

Is Cancer Man-made?

Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study review by University of Manchester scientists has strongly suggested.

A chemical found in everything from babies’ dummies to condoms may cause cancer, global health chiefs say.

The World Health Organisation has concluded that MBT, which is used in rubber manufacturing, ‘probably causes cancer’.

Dementia and Uncontrolled Innate Immunity

Scientists have identified a new cause of devastating neurological conditions such as Alzheimer’s disease and Parkinson’s.

They believe an out-of-control immune system may be to blame and say there is strong evidence the mental decline common to these diseases is caused by ‘auto-inflammation’,

This is where the body’s own immune system develops a persistent inflammatory response – and over time, this inflammation causes brain cells to die.

Super Scary Superbugs

(Reuters) – U.S. health officials on Thursday reported the first case in the country of a patient with an infection resistant to all known antibiotics, and expressed grave concern that the superbug could pose serious danger for routine infections if it spreads.
