An electronic device called the memristor could be our best hope for making practical chips that borrow design points from the human brain.
One in 17 people will suffer from a rare disease at some time in their lives. Most of these rare diseases have a genetic cause and often affect children, but proving which gene change causes a disease is a huge challenge.
Scientists have discovered a new genetic disease, which causes some children’s brains to develop abnormally, resulting in delayed intellectual development and often early onset cataracts.
The majority of patients with the condition, which is so new it doesn’t have a name yet, were also microcephalic, a birth defect where a baby’s head is smaller than expected when compared to babies of the same sex and age.
Researchers from the universities of Portsmouth and Southampton found that changes in a gene called coat protein complex 1 (COPB1) caused this rare genetic disease.
As expected, various samples of fruits, nuts, and other foods revealed very faint traces of cesium-137 when measured with a gamma detector, but even Kaste wasn’t prepared for what happened when he ran the same test with a jar of honey from a North Carolina farmer’s market.
Traces of radioactive fallout from nuclear tests in the 1950s and 1960s can still be found in American honey, new research reveals.
The radioactive isotope identified, cesium-137, falls below levels considered to be harmful – but the amounts measured nonetheless emphasize the lingering persistence of environmental contaminants in the nuclear age, even a half-century after international bomb tests ended.
Any discussion of rejuvenation biotechnology almost certainly includes the subject of and the objection that medical advances that directly address the various processes of aging will lead to an overpopulated world. Such dire predictions are a common theme in many discussions involving advances in medicine that could increase human lifespans.
Overpopulation is a word that gives the simple fact of population growth a negative connotation. It implies that an increase in the number of people will harm our lives in different ways, such as famine, scarcity of resources, excessive population density, increased risks of infectious diseases, and harm to the environment.
This concern, first raised by the work of 18th century reverend and scholar Thomas Malthus, has been a constant theme in both popular fiction and early foresights related to population growth. However, is it actually well-founded? We will be taking a deeper look at the historical and present population data and showing why is unlikely to happen.
There are several key technologies converging on an inevitable effect, namely a dramatic, explosive increase in human population. Currently around 40% of Earth’s total land area is dedicated to agricultural production to feed seven billion people, but, interestingly, while the human population will increase, the land area required to sustain this population will decrease, approaching zero land area to sustain a trillion human lives. In this era, bulk elements such as gold will have no value, since they will be so easy to produce by fusion separation of elements from bulk rock. Instead, value will be attached to biological material and, most importantly, new technologies themselves.
The several key emerging technologies that make this state of affairs unstoppable are listed along with aspects of their impact:
1) Most important is fusion energy, an unlimited, scalable energy, with no special fuel required to sustain it. This will allow nearly all agriculture to be contained in underground “vertical farm” buildings, extending thousands of feet downwards. Cheap artificially-lighted, climate-controlled environments will allow the maximum efficiency for all food crops. Thus, agriculture will take up close to zero surface area, largely produced underground on Earth or the Moon.
2) Crispr-gene edited foods, allowing the transformation of thousands of currently inedible plants into new types of fruits, vegetables and cereals, while also allowing diversity of currently-existing ones. Everything people eat has been genetically modified by thousands of years of human cultivation; that modification will take place over several years instead of thousands.
3) Acellular agriculture, where yeasts are bioengineered to produce milk and other proteins without any live mammals. Products using this method began to enter the market in 2020.

Oral treatment with a bacterial protein known as colonization factor antigen I (CFA/I) fimbriae, from Escherichia coli bacteria, has been shown to protect against several autoimmune diseases, including arthritis and type 1 diabetes. Another bacteria, called Lactococcus lactis, was recently adapted to express CFA/I fimbriae. These bacteria were shown to effectively suppress inflammation by the induction of regulatory T-cells (Tregs) — which are negative regulators of the immune system, meaning they work to shut down excessive inflammatory responses.
Oral treatment with a molecule produced by bacteria, called colonization factor antigen I, can reduce or halt the progression of Sjögren’s syndrome, a mouse study suggests.
Researchers believe these findings provide the basis for future testing in patients with Sjögren’s.
The study, “Stimulation of regulatory T cells with Lactococcus lactis expressing enterotoxigenic E. coli colonization factor antigen 1 retains salivary flow in a genetic model of Sjögren’s syndrome,” was published in the journal Arthritis Research & Therapy.
New research shows that members of a bee colony all have the same gut microbiome, which controls their smell—and thus their ability to separate family from foe.

In a new video released by jetpack maker Gravity Industries, a jetsuit-wearing special ops soldier from the Netherlands Maritime Special Operations Force can be seen boarding a ship — by flying there from a nearby pursuit vessel.
It’s a spectacular demonstration of Gravity Industries’ flying technology. Rather than having to pursue and approach the ship in the tailing vessel, the jetpack-enhanced soldier simply takes to the skies and effortlessly lands on the deck of the ship — in a fraction of the time boarding would have taken otherwise.
Gravity has quickly emerged as one of the biggest players in the jetpack field over the last few years, offering its jetsuit technologies to first responders and military forces around the world. It has even allowed journalists to give the suit a test drive, albeit with safety tethers.
