Apple announces first states that will let you keep a digital version of your driver’s license on your iPhone

Posted by in categories: mobile phones, security, transportation

Eight states will roll out a feature allowing users to add driver’s license and state IDs to Apple Wallet for iPhone and Apple Watch to use at security at participating airports, Apple announced Wednesday.

Arizona and Georgia are the first states to adopt the feature and Connecticut, Iowa, Kentucky, Maryland, Oklahoma and Utah will follow, though the company did not specify a timeline.

The news comes just months after Apple said at its Worldwide Developers Conference in June that it was working on the feature with the Transportation Security Administration. The update is a crucial step in Apple’s plan to replace physical wallets and will offer more convenience to travelers looking for a touchless airport experience, the company said.

Synthetic Biology Enables Microbes To Build Muscle Fibers That Are Tougher Than Kevlar

Posted by in categories: bioengineering, biological

No animals were harmed in the production of the synthetic muscle fibers, which are tougher than Kevlar.

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even Kevlar, then why not?

Don’t worry, this muscle could be produced without harming a single animal.

Immune cell ‘hubs’ discovered hiding in tumors

Posted by in category: biotech/medical

A tumor in the human body is like a city at war, bustling with cancer cells, immune cells, blood vessels, signaling molecules and surrounding tissue. A simple census of these players will provide some basic information on their battle, but won’t tell you their organization or strategy.

A team of researchers has gained new insight into this organization. They have discovered that immune cells in some human colorectal tumors gather together in clusters, like soldiers mobilizing in formation. By using a unique combination of single-cell profiling and imaging technologies, along with newly developed data analysis approaches, the scientists found a level of spatial organization of cells not observed before in tumors.

The findings, published in Cell, point to networks of interacting immune cells in certain types of colorectal tumors that tend to be more readily “seen” by the immune system. This suggests that cancers containing these hubs may be more likely to respond to cancer drugs called immunotherapies, which spur the immune system to kill . The scientists, from the Broad Institute of MIT and Harvard, Massachusetts General Hospital, MIT, the Evergrande Center for Immunologic Diseases at Brigham and Women’s Hospital and Harvard Medical School, and Dana-Farber Cancer Institute, say the study could shed light on how to make other tumors more responsive to such treatments.

Researchers discover way to switch on and speed up tendon healing

Posted by in categories: biotech/medical, engineering, health

The study investigated whether electrical therapy, coupled with exercise, would show promise in treating tendon disease or ruptures. It showed that tendon cell function and repair can be controlled through electrical stimulation from an implantable device which is powered by body movement.


Researchers at CÚRAM, the SFI Research Centre for Medical Devices based at NUI Galway, have shown how the simple act of walking can power an implantable stimulator device to speed up treatment of musculoskeletal diseases.

The results of have been published in the prestigious journal Advanced Materials.

Biologists Just Got Closer to The DNA Secrets That Stop Species From Interbreeding

Posted by in categories: biotech/medical, genetics

We think of DNA as the vitally important molecules that carry genetic instructions for most living things, including ourselves. But not all DNA actually codes proteins; now, we’re finding more and more functions involving the non-coding DNA scientists used to think of as ‘junk’.

A new study suggests that satellite DNA – a type of non-coding DNA arranged in long, repetitive, apparently nonsensical strings of genetic material – may be the reason why different species can’t successfully breed with each other.

It appears that satellite DNA plays an essential role in keeping all of a cell’s individual chromosomes together in a single nucleus, through the work of cellular proteins.

The fungal mind: on the evidence for mushroom intelligence

Posted by in categories: biological, neuroscience

Mushrooms and other kinds of fungi are often associated with witchcraft and are the subjects of longstanding superstitions. Witches dance inside fairy rings of mushrooms according to German folklore, while a French fable warns that anyone foolish enough to step inside these ‘sorcerer’s rings’ will be cursed by enormous toads with bulging eyes. These impressions come from the poisonous and psychoactive peculiarities of some species, as well as the overnight appearance of toadstool ring-formations.

Given the magical reputation of the fungi, claiming that they might be conscious is dangerous territory for a credentialled scientist. But in recent years, a body of remarkable experiments have shown that fungi operate as individuals, engage in decision-making, are capable of learning, and possess short-term memory. These findings highlight the spectacular sensitivity of such ‘simple’ organisms, and situate the human version of the mind within a spectrum of consciousness that might well span the entire natural world.

Before we explore the evidence for fungal intelligence, we need to consider the slippery vocabulary of cognitive science. Consciousness implies awareness, evidence of which might be expressed in an organism’s responsiveness or sensitivity to its surroundings. There is an implicit hierarchy here, with consciousness present in a smaller subset of species, while sensitivity applies to every living thing. Until recently, most philosophers and scientists awarded consciousness to big-brained animals and excluded other forms of life from this honour. The problem with this favouritism, as the cognitive psychologist Arthur Reber has pointed out, is that it’s impossible to identify a threshold level of awareness or responsiveness that separates conscious animals from the unconscious. We can escape this dilemma, however, once we allow ourselves to identify different versions of consciousness across a continuum of species, from apes to amoebas. That’s not to imply that all organisms possess rich emotional lives and are capable of thinking, although fungi do appear to express the biological rudiments of these faculties.

Mitochondrial Diseases May Potentially Be Improved by New Approach

Posted by in categories: biotech/medical, chemistry, genetics

Mitochondrial DNA diseases are common neurological conditions caused by mutations in the mitochondrial genome or nuclear genes responsible for its maintenance. Current treatments for these disorders are focused on the management of the symptoms, rather than the correction of biochemical defects caused by the mutation. Now, scientists at Kyoto University’s Institute for Integrated Cell-Material Science (iCeMS) in Japan report a new approach where mutant DNA sequences inside cellular mitochondria can be eliminated using a bespoke chemical compound. The approach may lead to better treatments for mitochondrial diseases.

Their findings are published in the journal Cell Chemical Biology in a paper titled, “Targeted elimination of mutated mitochondrial DNA by a multi-functional conjugate capable of sequence-specific adenine alkylation.”

“Mutations in mitochondrial DNA (mtDNA) cause mitochondrial diseases, characterized by abnormal mitochondrial function,” the researchers wrote. “Although eliminating mutated mtDNA has potential to cure mitochondrial diseases, no chemical-based drugs in clinical trials are capable of selective modulation of mtDNA mutations. Here, we construct a class of compounds encompassing pyrrole-imidazole polyamides (PIPs), mitochondria-penetrating peptide, and chlorambucil, an adenine-specific DNA-alkylating reagent.”
