Evacuation order to be lifted in NM ghost town
Residents and business owners will be allowed to return to the small privately run ghost town of Mogollon on Monday as fire crews battling the largest wildfire in New Mexico's recorded history continued to make progress.

Keeping up with embryogenesis: New microscope lets users track individual cells as they move, divide
(Medical Xpress) -- The transformation of a fertilized egg into a functioning animal requires thousands of cell divisions and intricate rearrangements of those cells. That process is captured with unprecedented speed and precision by a new imaging technology developed at the Howard Hughes Medical Institute’s Janelia Farm Research Campus, which lets users track each cell in an embryo as it takes shape over hours or days. -

Witnessed only seven times since the time of Galileo, Venus’s solar crossing on Tuesday (June 5) is a rare and historic event that shouldn’t be missed. Unless modern science discovers a way to delay or halt the aging process, this will be the last Venus transit we’ll ever get to see in our lifetime — the next transit won’t take place until 2117, or 105 years from now.

21:24Transgenic crops that produce insect-killing proteins from the bacterium Bacillus thuringiensis (Bt) have reduced reliance on insecticide sprays since 1996. Yet, just as insects become resistant to conventional insecticides, they also can evolve resistance to the Bt proteins in transgenic crops. Thus, to delay pest resistance, the U.S. Environmental Protection Agency (EPA) has required farmers to plant "refuges" of crops that do not produce Bt proteins near Bt crops. But how much refuge acreage is enough?

Is it reality? No, it's Truman Show delusion
Psychiatrists have identified a new form of psychosis: people who believe their life is a reality TV show or film
Two psychiatrists in the US have published some case studies that flesh out an idea that surfaced in 2008. In The Truman Show Delusion, brothers Joel and Ian Gold describe the stories of five psychiatric patients who recalled experiences similar to the 1998 film, in which Jim Carrey's character Truman Burbank is the unwitting star of a carefully controlled reality show. Three of the patients referenced the film directly.
We shouldn't be surprised, says Dr Peter Byrne, director of public education at the Royal College of Psychiatrists, who has treated people who have talked about Truman Show-like experiences. "Psychosis is a mixture of delusions – beliefs that are false, which arrive without any evidence or logic - but often also hallucinations, usually voices. It is true that some young people, because their experience includes reality TV, which is everywhere, and [CCTV] cameras which are also everywhere, thanks to Tony Blair and co, then hear a commentary about themselves and assume it's some kind of reality TV show. I've also heard the film Inception and the Matrix referenced [by people with psychosis]."
In 2005, Vaughan Bell, a clinical and research psychologist, wrote a paper about delusions involving the internet. Byrne remembers a patient who was convinced they had a microchip implanted in their head. "If you pick up a psychiatry textbook, they will say your patient thinks they're Jesus, or the old ones would say Napoleon," says Byrne. "They are just variations on a theme, and the themes are usually profound paranoid beliefs about being under surveillance, and at some level being special … a variation of a grandiose delusion. In the middle ages, someone might have thought they were a saint. It's the same story, just a different setting."

Tundra is by definition a cold, treeless landscape. But scientists have found that in a part of the Eurasian Arctic, willow and alder shrubs, once stunted by harsh weather, have been growing upward to the height of trees in recent decades.

LONDON (Reuters) - Plants and shrubs have colonised parts of the Arctic tundra in recent decades growing into small trees, a scientific study found, adding the change may lead to an increase in global warming pressures if replicated on a wider scale. Scientists from Finland and Oxford University investigated an area of 100,000 square km, roughly the size of Iceland, in the northwestern Eurasian tundra, stretching from western Siberia to Finland. ...

19:24Researchers at the University of California, Davis, report that ancient farmers had a stronger impact on the evolution of maize, or corn, than modern plant breeders have had on the grain — now one of the world's top production crops.

19:24A new study led by scientists at The Scripps Research Institute suggests that the replication process for DNA—the genetic instructions for living organisms that is composed of four bases (C, G, A and T)—is more open to unnatural letters than had previously been thought. An expanded "DNA alphabet" could carry more information than natural DNA, potentially coding for a much wider range of molecules and enabling a variety of powerful applications, from precise molecular probes and nanomachines to useful new life forms.

19:24Warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants. For instance, the Browns Ferry Nuclear Plant in Alabama had to shut down more than once last summer because the Tennessee River's water was too warm to use it for cooling.

17:24(Phys.org) -- Robotics researchers in Spain and the U.S. are studying bats for their design work on drones. Bat wings are highly articulated, with skeletons similar to those of human arms and hands. The researchers have built a drone that mimics the way a bat changes its wing shape in flight. Bats achieve an “amazing” level of maneuverability, says a researcher, mainly because of their capacity of changing wing morphology during flight. Specifically, the "Batbot" replicates the way a bat changes the profile of its wing between the downstroke and upstroke. By folding wings toward their bodies on the upstroke, bats use 35 percent less energy and reduce aerodynamic drag, according to researchers at Brown.

Intermittent hormone therapy for prostate cancer inferior to continuous therapy
An international randomized study finds intermittent androgen-deprivation therapy has some quality-of-life benefits, but overall survival times don’t measure up to those seen with continuous therapy.
