For decades, discovering novel antibiotics meant digging through the same patch of dirt. Biologists spent countless hours screening soil-dwelling microbes for properties known to kill harmful bacteria. But as superbugs resistant to existing antibiotics have spread widely, breakthroughs were becoming as rare as new places to dig. Now, artificial intelligence is giving scientists a reason to dramatically expand their search into databases of molecules that look nothing like existing antibiotics. A study published Thursday in the journal Cell describes how researchers at the Massachusetts Institute of Technology used machine learning to identify a molecule that appears capable of countering some of the world’s most formidable pathogens. advertisement When tested in mice, the molecule, dubbed halicin, effectively treated the gastrointestinal bug Clostridium difficile (C. diff), a common killer of hospitalized patients, and another type of drug-resistant bacteria that often causes infections in the blood, urinary tract, and lungs. The most surprising feature of the molecule? It is structurally distinct from existing antibiotics, the researchers said. It was found in a drug-repurposing database where it was initially identified as a possible treatment for diabetes, a feat that showcases the power of machine learning to support discovery efforts.

The world is now more reliant on technology than ever before. The emergence and growth of technology has had a positive impact on human life, but the convenience has, however, come with the risk of cyber attacks. If you use a tech device for whatever reason, then you’re highly likely to be exposed to a cyber attack. You’ll need to be protected, and that’s where cyber security comes in. Cyber security is the protection of electronic data and information. It’s the defense of electronic systems on devices, like computers, cell phones, servers, and networks, from malicious attacks. Regardless of who you are, it’s important to keep your data safe from unauthorized access. Here are some reasons why cyber security is crucial: There Are Different Types Of Cyber Attacks No one is safe from the threat of cyber attacks. These attacks include malware, phishing, man-in-the-middle, and drive-by attacks. Scary right? Wait till you hear about crypto-jacking. This is where criminals could compromise your computer and use it to steal resources, such as Bitcoins and other digital currencies. If they can get to your computer, then they could easily steal your data. You need cyber security if you want to stand a chance against these threats. Increase In Cybercrimes The fast development of technology, such as fast broadband, better gadgets, and cloud computing, has led to an increase in the number of connected devices. According to some surveys, there’ll be about 21.1 billion networked devices in the world in 2021. This, with the development of the dark web, has created a fertile ground for cybercrime activities. Cyber security can, nonetheless, minimize...
Laial Al-Mansoury KUWAIT: The need for a National Cyber Security Centre to tackle the post-COVID cyber threat has never been greater. That’s the message from a panel of leading global cyber security experts at the upcoming 8th eGovernment Forum (EGOV8) that convenes virtually on 30 and 31 March under the motto of ‘Integrated E-Government, an Urgent Post Corona Need’. Government, the private sector and individuals are all increasingly dependent on the internet and digital technology, and the pandemic has accelerated this shift to online services and home working. Yet, at the same time, the threat of cyber-attack is increasing at a frightening rate. Last year saw a significant increase in cyber-attacks including vaccine hacking and aggressive ransomware attacks, many linked to the pandemic. Experts estimate that global cyber-crime now costs in excess of $6 trillion and is growing at 15 percent per annum. Gen (Ret) Keith Alexander, who led America’s National Security Agency, established US CYBERCOMMAND and is Founder and co-CEO of IronNet Cybersecurity; Dr Henry Pearson, the UK Government’s Cyber Security Ambassador; and Conrad Prince, formerly deputy head of the UK’s cyber agency GCHQ and now a senior adviser to a leading global vendor in cyber security solutions, will speak on a panel chaired by Eng Laial Abdullah Al-Mansoury, Director of Information Security and Emergency Response at CITRA. Their debate will focus on why nations need to adopt a national coordinated approach to defending against these cyber threats to be resilient in cyber-space. Alexander said, “We face the beginning of a digital arms race in which adversaries are using cybersecurity attacks as a tool to wreak havoc, including...

I imagine there are a lot of people who tried reading the wikipedia article , got frustrated and gave up wishing someone would just give them a high-level explanation. That’s what this is.The goal is be accessible to anyone — which means that there’s a lot of generalizations. But who cares? If this gets anyone more interested in ML, then mission accomplished. What is machine learning? Machine learning is the idea that there are generic algorithms that can tell you something interesting about a set of data without you having to write any custom code specific to the problem....
Welcome to Cyber Security Today. This is the Week In Review edition for the week ending Friday March 19th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. With me today is Dinah Davis, vice-president of research and development at Arctic Wolf. In a few minutes we’ll delve into one item that’s been in the news. But first a review of what happened in the last seven days: Hate getting robotic calls on your phone? The U.S. Federal Communications Commission has given you a bit of revenge. This week it fined two Texas-based telemarketers $225 million for running an automated phone scam that spoofed the phone numbers of real insurance companies. Their servers made millions of robocalls a day. In addition to going after scammers in the U.S. the agency also issued cease and desist letters this week to robocall companies in the United Kingdom., and six firms here in Canada. says Russian President Vladimir Putin authorized Russian government organizations to try and undermine American public confidence in last November’s elections. However, unlike 2016 these efforts didn’t include attempts to get into the election infrastructure. Iran also ran a misinformation campaign to undercut President Trump’s chances of re-election. The report concluded the registration and voting process itself was untouched by foreign actors. A teenager believed to be the leader of a group that hacked Twitter accounts of people including celebrities last summer to spread a bitcoin scam is going to jail. The teen pleaded guilty to four charges in a Florida court and will serve three years in a facility for juveniles. Meanwhile a judge in Atlanta sentenced a...
Ransomware group now threatening customers of victims, ransomware attack could cost company over $20 million and update your Apple devices. Welcome to Cyber Security Today. It’s Monday March 29th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. A ransomware attack on U.S. managed services provider CompuCom will be expensive. In a security filing on Friday the company said it could cost up to $20 million to restore crippled IT systems. In addition, it could lose up to $8 million in revenue because some services had to be suspended to some customers. Some of the costs could be covered by cyber insurance. CompuCom was hit at the beginning of the month. By March 17th it had largely restored its ability to deliver service to customers. It says it will have service delivery restored to substantially all customers by Wednesday. Meanwhile Canadian wireless component manufacturer Sierra Wireless says it has resumed production and started to recover internal systems following a ransomware attack. That attack started March 20th. The company says the attack did not hit customer products or systems. Sierra Wireless makes modules embedded in industrial systems from pipelines to transport trucks. And a ransomware group has found a new way to pressure victim organizations to pay up: It’s contacting customers and warning them their sensitive data was copied from the ransomware victim. The crooks warn that data will be publicly released unless the victim firm pays a ransom. According to the Bleeping Computer news service, this tactic is now being used by a ransomware group called Clop. Squeezing customers to put pressure on others is a tactic that will...
