Flowers have bloomed for 240m years

Flowers appeared on Earth 100 million years earlier than was previously thought, according to evidence from ancient fossilised pollen grains.

The beautifully preserved pollen, found in cores drilled from a site in northern Switzerland, is dated to 240 million years ago. Until recently scientists were convinced flowering plants only emerged in the Early Cretaceous period around 140 million years ago, when dinosaurs ruled the Earth.

In 2004, scientists identified much older flowering plant-like pollen from cores from the bottom of the Barents Sea, south of Spitsbergen in Norway, but the evidence was not conclusive. The new find appears to confirm an ancient origin for flowering plants, or angiosperms, which evolved from extinct cousins of conifers, ginkgos, cycads and seed ferns.

It also suggests the primitive flowers were blossoming across a broad ecological range. The research, led by Dr Peter Hochuli from the University of Zurich, appears in the latest issue of the journal Frontiers in Plant Science.

Alternative to antibiotics
As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressure plasmas attack the prokaryote's cell envelope, proteins and DNA. "This is too great a challenge for the repair mechanisms and the stress response systems of bacteria," says Junior Professor Dr Julia Bandow, Head of the Junior Research Group Microbial Antibiotic Research at the RUB. "In order to develop plasmas for specific applications, for example for treating chronic wounds or for root canal disinfection, it is important to understand how they affect cells. Thus, undesirable side effects may be avoided right from the start." The team reports in the Journal of the Royal Society Interface. Plasmas affect cell envelope, DNA and proteins

Depending on their specific composition, plasmas may contain different components, for example ions, radicals or light in the ultraviolet spectrum, so-called UV photons. Until now, scientists have not understood which components of the complex mixture contribute to which extent to the antibacterial effect. Julia Bandow's team has analysed the effect of UV photons and reactive particles, namely radicals and ozone, on both the cellular level and on the level of single biomolecules, namely DNA and proteins. On the cellular level, the reactive particles alone were most effective: they destroyed the cell envelope. On the molecular level, both plasma components were effective. Both UV radiation and reactive particles damaged the DNA; in addition, the reactive particles inactivated proteins.

No effective antibiotics in ten years' time?

Atmospheric-pressure plasmas are already being used as surgical tools, for example in nasal and intestinal polyp extraction. Their properties as disinfectants may also be of interest with regard to medical applications. "In ten years, bacteria might have developed resistance against all antibiotics that are available to us today," says Julia Bandow. Without antibiotics, surgery would become impossible due to high infection rates.

A cure for jetlag? Scientists discover body clock 'reset button'

The findings could reduce the symptoms of jet lag after travelling through different time zones

Scientists have discovered the body clock 'reset button', taking them one step closer to tweaking the clock in order to make jet lag and shift work less painful.

The findings could reduce the symptoms of travelling through different time zones and working unsociable hours, which often makes people either tired or unable to sleep. Results from the study, published in journal Science, suggest the newly-found button could be used to switch the master clock to a new time zone, for example from London to Beijing, in just one day.

A team based at Kyoto University in Japan discovered the 'reset button' in the brain. There are clocks located throughout the body but the master clock is found within the brain, where it works to keep the body in tune with the world around us, creating fatigue at night and alertness during daylight.

The clock uses light to monitor time, but adjusts slowly. For every time zone travelled, it takes the body approximately a full day to catch up, according to the BBC.

Disinhibition neurons discovered
Dr. Adam Kepecs led a group of a team of neuroscientists at Cold Spring Harbor Laboratory that is the first to elucidate a class of inhibitory neurons that specialize in inhibiting the action of other inhibitory neurons. The research was published in the Oct. 6, 2013, edition of the journal Nature.

The new class of neurons called VIP interneurons provides a secondary layer of inhibition of neuronal expression for both inhibitory neurons and minimizing the expression of neurons that cause excitation to occur in brain. The VIP interneurons release vasoactive intestinal polypeptide (VIP) and function in the auditory cortex and the medial prefrontal cortex.

New treatments to tackle allergies
Scientists have zeroed-in on new treatments for people with allergies to grasses and to dust mites.

The treatments are from a new class of therapy, known as 'synthetic peptide immuno-regulatory epitopes', or SPIREs.

There are two treatments, one for grass allergy, which is commonly known as hay fever, and the other for dust mite allergy.

These are expected to help people who, as a reaction to grass pollen or the tiny bugs that live in house dust, have sneezing bouts, itching eyes and a running nose, impacting their productivity at school or work.

The two studies were conducted by Adiga Life Sciences, a joint venture between McMaster University and Circassia, a UK-based biotechnology company, and was supported by St. Joseph's Healthcare Hamilton.

It is estimated that these allergens together are responsible for more than 50 percent of allergic respiratory disease. Between 15 and 25 per cent of the population in North America and Europe is sensitive to pollen from different grass species.

One in four people is sensitised to house dust mites, more than any other common allergen, which includes millions of people in these regions, reports Science Daily.

'Brain training' may boost working memory, but not intelligence
Brain training games, apps, and websites are popular and it's not hard to see why -- who wouldn't want to give their mental abilities a boost? New research suggests that brain training programs might strengthen your ability to hold information in mind, but they won't bring any benefits to the kind of intelligence that helps you reason and solve problems. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

General fluid intelligence is the ability to infer relationships, do complex reasoning, and solve novel problems.

Money doesn't grow on trees - but gold does

Scientists in Australia have confirmed the presence of gold particles in the leaves of eucalyptus plants
Australia based researchers found the gold particles hidden within eucalyptus tree foliage, indicating that gold deposits may also be buried many metres below.

The grains growing within the leaves are approximately one fifth the diameter of a human hair, making the discovery unlikely to start a gold rush. However, it can provide a unique opportunity for mineral exploration.

Geochemists from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRPO) said eucalyptus trees in western Australia are drawing up gold particles from the earth via their root system and depositing it their leaves and branches.

Although the amounts found were tiny, their presence could indicate gold ore deposits buried up to tens of metres underground and under sediments that are up to 60 million years old.

Global warming led to dwarfism in mammals -- twice

Mammal body size decreased significantly during at least two ancient global warming events. A new finding that suggests a similar outcome is possible in response to human-caused climate change, according to a University of Michigan paleontologist and his colleagues. Researchers have known for years that mammals such as primates and the groups that include horses and deer became much smaller during a period of warming, called the Paleocene-Eocene Thermal Maximum (PETM), about 55 million years ago.

Now U-M paleontologist Philip Gingerich and his colleagues have found evidence that mammalian "dwarfing" also occurred during a separate, smaller global warming event that occurred about 2 million years after the PETM, around 53 million years ago.

"The fact that it happened twice significantly increases our confidence that we're seeing cause and effect, that one interesting response to global warming in the past was a substantial decrease in body size in mammalian species," said Gingerich, a professor of earth and environmental sciences.

The research team also includes scientists from the University of New Hampshire, Colorado College and the California Institute of Technology. The researchers are scheduled to present their findings Friday, Nov. 1, in Los Angeles at the annual meeting of the Society of Vertebrate Paleontology.

They concluded that decreased body size "seems to be a common evolutionary response" by mammals to extreme global warming events, known as hyperthermals, "and thus may be a predictable natural response for some lineages to future global warming."

The parallels between ancient hyperthermals and modern-day warming make studies of the fossil record particularly valuable, said team member Will Clyde of the University of New Hampshire.

"Developing a better understanding of the relationship between mammalian body size change and greenhouse gas-induced global warming during the geological past may help us predict ecological changes that may occur in response to current changes in Earth's climate," Clyde said.

In 2006, Gingerich proposed that mammalian dwarfing could be a response to the lower nutritional value of plants grown under elevated carbon dioxide levels. Under such conditions, plants grow quickly but are less nutritious than they would normally be.

Animals eating such plants might adapt by becoming smaller over time. Evidence from the ETM2 fossils is consistent with that hypothesis, and research on the topic is ongoing, Gingerich said.

The research was funded by the National Science Foundation (EAR0958821), Geological Society of America, Paleontological Society and Sigma Xi.

What Is 4-D Printing?

An M.I.T. lab is tweaking the idea of 3-D printing with the help of smart materials that continue to change even after they leave the printer
The biggest breakthroughs in how we make things lie not in the technology to manipulate materials but in the materials themselves. Such is the thinking behind “4-D printing,” an experimental approach to manufacturing that expands on much-hyped 3-D printing processes. Instead of building static three-dimensional items from layers of plastics or metals, 4-D printing employs dynamic materials that continue to evolve in response to their environment.

This new wrinkle in the maker movement comes courtesy of the Massachusetts Institute of Technology’s Self-Assembly Lab, where director Skylar Tibbits and his team are experimenting with so-called “programmable materials.” The researchers print these substances using a 3-D printer and then watch as the fourth dimension—time—takes over and the materials change shape or automatically reassemble in new patterns.

Improvements in software, computers and assembly processes have enabled more complex designs and greater automation when translating designs into actual things.

Where Old Buildings Withstand Earthquakes Best

Buildings constructed during the Middle Ages in Liechtenstein ride out earthquakes better than those built to modern standards

Old buildings may be the safest spot to be when in Liechtenstein.

A new study in this tiny European country reveals that buildings constructed during the Middle Ages ride out earthquakes better than those built to modern standards. The reason for this counterintuitive truth appears to be that old buildings were constructed so that the floor doesn't attach to the walls.

"Instead of rolling like a boat," these structures actually stabilize during quakes, said study researcher Maria Brunhart-Lupo, a geologist at the Colorado School of Mines in Golden, Colo.

Vapours from damp buildings may trigger Parkinson’s

A vapour known as “mushroom alcohol” which is present in damp, mouldy buildings can damage the nerve cells of the brain responsible for Parkinson’s disease, scientists said.

A study has found that the compound, called 1-octen-3-ol, leads to the degeneration of two genes involved with the transport and storage of dopamine, the neurotransmitter in the brain that is lost in patients with Parkinson’s.

The researchers suggest that the volatile substances given off by mildew and other fungi growing in damp houses may be a significant risk factor in the development of the degenerative brain disease, which is thought to have environmental as well as genetic causes.

The study was carried out on the dopamine system of fruit flies, a recognised animal “model” of Parkinson’s disease, and the researchers calculated that mushroom alcohol was more toxic to these specialised nerves than benzene – a poisonous chemical known to cause genetic damage.

“These findings are of particular interest given recent epidemiological studies that have raised the concern of neuropsychological impairments and movement disorders in human populations exposed to mouldy and water-damaged buildings,” the scientists said in the study published in the journal Proceedings of the National Academy of Sciences. “Increased incidence of Parkinson’s disease is seen in rural populations, where it is usually attributed to pesticide exposure. However, the prevalence of mould and mushroom in these environments may provide another plausible risk factor for the development of Parkinson’s disease.”

Until recently, the search for environmental factors that could trigger the disease has focused largely on man-made chemicals, such as pesticides. However, natural compounds could be equally to blame, said Arati Inamdar of Rutgers University.
