Studies exploring the neural processes involved in cell regeneration are of crucial importance, as they could pave the way towards the development of more effective treatments for many pathologies associated with the mutations or deterioration of cells. Microglia, the brainโ€™s resident immune cells, become active in response to pathologies, sometimes leading to chronic inflammation and the scarring of tissue.

Already Spread to Every Continent: Unusual Fungus Has the Potential To Become a Global Health Problem

Posted by in categories: biotech/medical, health

Have you ever heard of the yeast Candida auris? If not, you are most likely not the only one since it hasnโ€™t garnered much attention. Yet. That could change.

Candida aurisโ€™s story begins in 2009 when a Japanese woman in her 70s is admitted to the Tokyo Metropolitan Geriatric Hospital. Her ear sometimes discharges something, and the doctors routinely use a cotton swab to collect samples of it. To determine what is causing the infection, they analyze the sample.

It turns out that a yeast, different from other known yeasts, is at play. Weโ€™ve all heard of bakerโ€™s yeast, a friendly microorganism used to make beer and bread. Candida auris and other Candida yeast species are extremely different; they cause serious and persistent infections that are difficult to treat with known antibiotics.

GodFather Android malware targets 400 banks, crypto exchanges

Posted by in categories: cryptocurrencies, cybercrime/malcode, finance, robotics/AI

An Android banking malware named โ€˜Godfatherโ€™ has been targeting users in 16 countries, attempting to steal account credentials for over 400 online banking sites and cryptocurrency exchanges.

The malware generates login screens overlaid on top of the banking and crypto exchange appsโ€™ login forms when victims attempt to log in to the site, tricking the user into entering their credentials on well-crafted HTML phishing pages.

The Godfather trojan was discovered by Group-IB analysts, who believe it is the successor of Anubis, a once widely-used banking trojan that gradually fell out of use due to its inability to bypass newer Android defenses.

Study shows how machine learning could predict rare disastrous events, like earthquakes or pandemics

Posted by in categories: biotech/medical, information science, robotics/AI

PROVIDENCE, R.I. [Brown University] โ€” When it comes to predicting disasters brought on by extreme events (think earthquakes, pandemics or โ€œrogue wavesโ€ that could destroy coastal structures), computational modeling faces an almost insurmountable challenge: Statistically speaking, these events are so rare that thereโ€™s just not enough data on them to use predictive models to accurately forecast when theyโ€™ll happen next.

But a team of researchers from Brown University and Massachusetts Institute of Technology say it doesnโ€™t have to be that way.

In a new study in Nature Computational Science, the scientists describe how they combined statistical algorithms โ€” which need less data to make accurate, efficient predictions โ€” with a powerful machine learning technique developed at Brown and trained it to predict scenarios, probabilities and sometimes even the timeline of rare events despite the lack of historical record on them.

The cloud out of space? Scientists scrambling to prevent global data storage crisis

Posted by in categories: computing, finance

BIRMINGHAM, United Kingdom โ€” Servers around the world could soon face a massive data storage crunch, thanks to the โ€œmind-blowing amountโ€ of information people store digitally every day.

Researchers from Aston University say the global datasphere โ€” the total amount of data worldwide โ€” will increase by 300 percent within the next three years. Currently, all of this data sits in banks of servers stored in huge warehouses (data centers).

Worldโ€™s first โ€˜artificial womb facility,โ€™ will let parents design childโ€™s height, strength, intelligence

Posted by in categories: biotech/medical, genetics

BERLIN โ€” A biotechnologist in Germany is developing the worldโ€™s first artificial womb facility, and it lets you choose babyโ€™s characteristics from a menu. EctoLife, able to grow 30,000 babies a year, is said to be based on over fifty years of groundbreaking scientific research.

The concept is the brainchild of Berlin-based Hashem Al-Ghaili. He says the facilities would allow infertile couples to conceive a baby and become the true biological parents of their own offspring.

A so-called โ€˜Elite Packageโ€™ would allow you to genetically engineer the embryo before implanting it into the artificial womb. Everything from eye and hair color to strength, height, and intelligence can be chosen, and inherited genetic diseases can be avoided.

Chemists make the unimaginable possible in crystalline materials discovery

Posted by in categories: chemistry, materials

The worldโ€™s best artists can take a handful of differently colored paints and create a museum-worthy canvas that looks like nothing else. They do so by drawing upon inspiration, knowledge of whatโ€™s been done in the past and design rules they learned after years in the studio.

Chemists work in a similar way when inventing new compounds. Researchers at the U.S. Department of Energyโ€™s (DOE) Argonne National Laboratory, Northwestern University and The University of Chicago have developed a new method for discovering and making new with two or more elements.

โ€œWe expect that our work will prove extremely valuable to the chemistry, materials and condensed matter communities for synthesizing new and currently unpredictable materials with exotic properties,โ€ said Mercouri Kanatzidis, a chemistry professor at Northwestern with a joint appointment at Argonne.

A Target to Toxicity of Cancer Therapies

Posted by in category: biotech/medical

Many medical treatments have toxicities, sometimes called adverse events, which can complicate a patientโ€™s treatment regimen. Treatment-related adverse events can range from mild symptoms, like transient fatigue or nausea, to severe and lethal occurrences, including cardiac toxicity.

Cardiac toxicity, which manifests as indications like acute myocardial infarction (MI), and angina pectoris (AP), can occur in cancer survivors, even several years following successful treatment. The onset of heart-related adverse events long after treatment is known as late cardiac toxicity, which can become a lethal complication of cancer therapies like radiation and chemotherapy.

Artificial wombs: The coming era of motherless births?

Posted by in categories: biotech/medical, innovation

S cientifically, itโ€™s called ectogenesis, a term coined by J.B.S. Haldane in 1924. A hugely influential science popularizer, Haldane did for his generation what Carl Sagan did later in the century. He got people thinking and talking about the implications of science and technology on our civilization, and did not shy away from inventing new words in order to do so. Describing ectogenesis as pregnancy occurring in an artificial environment, from fertilization to birth, Haldane predicted that by 2074 this would account for more than 70 percent of human births.

His prediction may yet be on target.

In discussing the idea in his work Daedalus โ€“a reference to the inventor in Greek mythology who, through his inventions, strived to bring humans to the level of the godsโ€“Haldane was diving into issues of his time, namely eugenics and the first widespread debates over contraception and population control.
