Kiriform tech allows flat objects to be twisted into 3D shapes
Posted by Genevieve Klien in category: materials
Ordinarily, if you’re building something, you don’t want the materials to buckle under pressure. In a new Harvard University-designed system, however, that buckling action allows flat-packed objects to be twisted into useful three-dimensional forms.
Most existing “buckling-induced deployable structures” consist of linked straight pieces that are popped into shape via straight linear motion, which often requires a fair bit of force to be applied by the user. Folding chairs are one frequently frustrating example.
Seeking an easier alternative, Harvard researchers instead set about building items made up of linked curved pieces. Generally speaking, curved objects (such as beams) are less mechanically stable than their straight counterparts. In most scenarios, this is an undesirable quality. In the case of pop-up devices, though, it means that they’re easier to buckle into the desired form.

Black holes eat neutron stars for breakfast — and burp out gravitational waves
Posted by Atanas Atanasov in categories: cosmology, physics
“In physics, we often say that exceptional discoveries require exceptionally strong evidence.”
Within the space of ten days, LIGO detected gravitational waves that prove black holes can form binaries with neutron stars.

Big oil and gas kept a dirty secret for decades. Now they may pay the price
Posted by Jason Blain in category: climatology
Almost all the lawsuits draw on the oil industry’s own records as the foundation for claims that it covered up the growing threat to life caused by its products.
Shell, like other oil companies, had decades to prepare for those consequences after it was forewarned by its own research. In 1958, one of its executives, Charles Jones, presented a paper to the industry’s trade group, the American Petroleum Institute (API), warning about increased carbon emissions from car exhaust. Other research followed through the 1960s, leading a White House advisory committee to express concern at measurable and perhaps marked changes in climate by 2000.
With an unprecedented wave of lawsuits, America’s petroleum giants face a reckoning for the environmental devastation caused by fossil fuels – and covering up what they knew along the way.

Experimental device could treat ear infections using jets of plasma
Posted by Jason Blain in category: biotech/medical
Bacterial infections of the middle ear are quite common, particularly in children, yet they can be difficult to treat. An experimental new device has been designed to help, by zapping the bacteria with plasma.
Usually, such infections are treated with topically applied antibiotics. According to the University of Illinois at Urbana-Champaign, however, such an approach is ineffective in over 30 percent of acute infections. This is because the antibiotics have trouble penetrating the bacterial biofilm that has formed on the surface of the inner ear tissue.
Additionally, the greater the amount of antibiotics that are used, the greater the chances that the bacteria will develop a tolerance to them over time. With these limitations in mind, U Illinois scientists set out to develop an alternative treatment, or at least one that would allow smaller amounts of antibiotics to be more effective.

Mouse and human germline cells appear to reset their biological age
Posted by Kevin Huang in categories: biotech/medical, genetics, life extension
Not sure how interesting this will be to people who know a lot on aging/longevity research.
A team of researchers at Brigham and Women’s Hospital and Harvard Medical School have found evidence of mouse and human germline cells resetting their biological age. In their paper published in the journal Science Advances, the group describes their study of the aging process in germline cells and what they found by doing so.
As animals grow older, all of the cells in their body replicate themselves repeatedly. As the process continues, errors in replicating and other external factors (such as exposure to pollutants) lead to gradual decay in cell quality, which is all part of the natural aging process. In this new effort, the researchers have found evidence showing that germline cells have a mechanism for resetting this process, allowing offspring to reset their aging clocks.
