DNA can be collected from air, scientists show for first time

Posted by in category: biotech/medical

In a first, scientists have revealed that animal and human DNA can be plucked straight out of thin air. The development heralds a promising new scientific technique with possible applications for ecology, forensics, and medicine, according to a new study.


“For example, this technique could help us to better understand the transmission of airborne diseases such as COVID-19.”

The research team is working with partners in industry, including the company NatureMetrics, to see how the technique can be applied in other ways, the university said.

Diamond battery powered by nuclear waste runs for 28,000 years

Posted by in categories: mobile phones, nanotechnology, nuclear energy

Would you use one in your phone though?


A U.S. startup combined radioactive isotopes from nuclear waste with ultra-slim layers of nanodiamonds to assemble a ridiculous battery that allegedly can last 28000 years.

According to the California startup in question, called NDB (Nano Diamond Battery), their product is a “high-power diamond-based alpha, beta, and neutron voltaic battery.”

Brown Under Cyberattack: Some Systems Shut Down, University Calls Incident “Utmost Priority”

Posted by in categories: cybercrime/malcode, education

Brown University is facing a cyberattack that has forced the school to shut some systems down — in an event that Brown is calling an “utmost priority.”

Jack Wrenn, a fifth-year doctoral candidate, said that official information was still “frustratingly scant” as of Wednesday night.

Wrenn provided a timeline as to what he understood transpired, and when the university community was notified.

New Cheap Electric Cars Show How Automakers Are Conning The U.S. Market, Inflating Prices

Posted by in categories: sustainability, transportation

European automaker Renault debuted its new cheap electric cars, the Kwid series, in India for a little over $6000 USD. The incredibly low price has left many consumers wondering why certain counties have access to cheap EV cars, while buyers in Europe and the United States are expected to pay more than quadruple that price for similar vehicles. It turns out there is a conspiracy and Europeans and North Americans who want electric cars are getting gouged by automakers, and it all has to do with gaining access to new markets.

The Kwid specifications are nearly identical to a Dacia, also a Renault brand. The difference: a European Dacia is double the price of an Indian Kwid. Meanwhile, the U.S. market misses entirely on either of these vehicles. The only electric cars available in America are dominated by premium brands and high price tags, making them unaffordable for most.

How Metaphors Shape Our Ideas About Education

Posted by in categories: education, electronics

An interview with Dr. Yulia Turchaninova on What would be your take on that?


Many parents employ a “job” metaphor for school. But as a parent, do you bring your work home every night? Do it over the weekend? Take it with you on vacation? And if you do, are you still eager to work on it when the whole family sits down to chat, play and watch TV after dinner? And how many direct bosses do you have above you? How about six to eight different ones a day, each with their own quirks? Do they replace each other at the ring of the bell, demanding that you instantly and completely switch to the new assignment, regardless of whether you have completed the previous one, and do it in their idiosyncratic way? And if you do, is this the kind of life that you would wish for your children?

Brodsky: So, what would be a better way of treating our metaphors?

Vaccine passports launched in Las Vegas but privacy, choice still concerns

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

A handful of passports are already in the works, including two in Las Vegas. It is not yet clear if any Las Vegas businesses will limit access solely to vaccinated guests.


Las Vegas is no stranger to exclusive VIP lists, but there’s a new way of limiting guest access coming to town: vaccine passports.

These digital credential systems can show whether someone has been vaccinated against COVID-19 and can help businesses limit access to those who have been inoculated. The systems were designed to increase health and safety at various venues, but experts warn of pushback over concerns on privacy and personal choice.

Artificial Life Forged in a Lab? Scientists Create Synthetic Cell That Grows and Divides Normally

Posted by in category: particle physics

New findings shed light on mechanisms controlling the most basic processes of life.

Five years ago, scientists created a single-celled synthetic organism that, with only 473 genes, was the simplest living cell ever known. However, this bacteria-like organism behaved strangely when growing and dividing, producing cells with wildly different shapes and sizes.

Now, scientists have identified seven genes that can be added to tame the cells’ unruly nature, causing them to neatly divide into uniform orbs. This achievement, a collaboration between the J. Craig Venter Institute (JCVI), the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) Center for Bits and Atoms, is described in the journal Cell.

Simulating the Universe a Trillionth of a Second After the Big Bang

Posted by in categories: computing, cosmology

The Big Bang remains the best way to explain what happened at the beginning of the Universe. However, the incredible energies flowing during the early part of the bang are almost incomprehensive to our everyday experience. Luckily, computers aren’t so attached to normal human ways of thinking and have long been used to model the early universe right after the Bang. Now, a team from the University of Göttingen have created the most comprehensive model of what exactly happened in that very early stage of the universe – one trillionth of a second after the Big Bang.

Just because a computer can model it doesn’t really mean it is easy to explain, however. The model includes clumps of energy weighing grams, but which are one millionth the size of a single proton. These energy structures defined what would eventually become the structure of the universe today, with tiny variations in the original structure resulting in entire galaxies or complete voids, depending on the presence or absence of matter.

Throwing this much computing power at a physical space one millionth the size of a proton was no mean feat. “It is probably the largest simulation of the smallest area of the Universe that has been carried out thus far” says Professor Jens Niemeyer, who leads the group carrying out the research.

The Closest Star Cluster to Earth is Being Dismantled in Front of our Eyes

Posted by in categories: computing, cosmology, mapping

Star clusters are interesting inhabitants of the sky. They vary in sizes, distances, and number of stars, but almost all are spectacular to look at. And most of them are in the process of being torn apart. That is certainly the case for the Hyades star cluster – the closest one to Earth at only 153 light years away. The problem is, there is something causing a lot more destruction than would be expected given the mass and energy in the surrounding space. Now, a team of scientists from ESA have a theory as to what the cause of the destruction might be – a mysterious dark matter sub-halo.

This novel theory extends from findings gleaned from data collected by GAIA, ESA’s star mapping satellite. The GAIA team expected to see what are called “tidal tails” trailing and leading the star cluster as it moves throughout the galaxy. These tails are formed when some stars are forced to the outer edges of the cluster, and then pulled by the gravitational pull of the galaxy itself, pushing some stars forward in their journey through the galaxy, while other stars are pulled further behind.

The GAIA team did find tidal tails on either side of the Hyades cluster when they observed it. However, they were extraordinarily long – thousands of light years across the galaxy, each holding thousands of stars. Observing them in their entirety was only possible because of the GAIA data and a computer model that Dr. Tereza Jerabkova, an ESA research fellow, developed with her colleagues.

Social Determinants of Health Impact Fetal Brain Development

Posted by in categories: biotech/medical, education, employment, health, neuroscience

New data from Children’s National Hospital shows parental experience with a number of social determinants of health can ultimately impact brain development in utero, something researchers said should suggest future community health intervention among pregnant people. The data, published in JAMA Network Open, specifically found poorer brain development in fetuses among pregnant people with low socioeconomic status (SES), low educational attainment, and limited employment opportunity.


New data from Children’s National Hospital has found that social determinants of health like income, education, and occupation can impact fetal brain development, following that child into life.
