The Cloud Security Alliance (CSA), a leading IT trade association, has published its first report on risks and recommendations for connected-vehicle security, ahead of when driverless cars are about to see volume production in the near future.
The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.
Your Android phone could be listening to ultrasonic ad beacons behind your back. The unwelcome news comes year after app developer SilverPush promised to quit using its (creepy!) eavesdropping software.
Usually, the mucus lining of the female genital tract presents a barrier that helps prevent infections. But, somehow, the bacteria that causes gonorrhea gets around and through that barrier to invade the female genital tract.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
No one can dispute the evolutionary success of bugs. The oldest insect fossils were found encased in crystallized mineral silica in Scotland in 1926, and they're between 396 and 407 million years old.
Are you a follower or a leader? No matter how you respond, we all know that leader is a more desirable position to hold. Great leaders typically share a few qualities—confidence, intelligence, and strength, to name a few—but one of the most intriguing is their appearance. With the right facial structure, and some well-rehearsed expressions, you can trick others into thinking you're leader material.
Decisions are rarely easy to make, and there are countless ways to mull your options over. You can sleep on it, pluck flower petals, make a list of pros and cons, or even follow the advice of a psychic. Yet to make the best decision possible, you might want to consider holding off until a certain time of the day—or even until you feel specific emotions. The state you find yourself in has significant impact on each decision you make.
No one wants to appear stupid. Whether you rely on lengthy, complicated vocabulary to show your smarts, or enjoy highlighting your speedy mental math skills, everyone prefers emphasizing intelligence over hiding it.

Most augmented reality experiences are purely visual, with spatial audio gaining in popularity to make visual experiences more realistic. However, leveraging the sense of touch may be the next frontier for AR experiences.
A team of academics from three different universities and two private companies have just discovered a new vulnerability that affects almost every Android device since 2012. The vulnerability is known as RAMpage, and it could be used to gain complete control over the device.
More than one in ten people in the US have type 2 diabetes — that's over 29 million people. It's characterized by excessive sugar (glucose) in the blood due to the development of resistance to insulin, the hormone that normally metabolizes glucose.
The number of households in the US that go hungry because they lack money for food hit a high of almost 15% in 2011. While that number continues to decline, nearly 13% of American households still go hungry.
Research group OpenAI, a research institute co-founded by Tesla CEO Elon Musk, says it is possible to trick driverless cars' neural networks into mistaking images for something else.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
By connecting the dots between theory and real-life effect, two new studies offer more proof that neonicotinoid insecticides are causing extensive damage to honeybee colonies.
People who have heart disease get shingles more often than others, and the reason has eluded scientists since they first discovered the link. A new study has found a connection, and it lies in a defective white cell with a sweet tooth.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
Even though the Ebola virus was discovered as recently as 1976, over 30,000 people have been infected since, and half have died a horrible death. Since there's no way to cure the infection, the world desperately needs a way to prevent it — and the five similar viruses in its family, the ebolaviruses.
Fighting fire with fire, scientists are harnessing the adaptability of helpful microbes to challenge the adaptability of deadly microbes. What are we talking about? Hunting with phages — viruses that attack and kill bacteria.
Being infected with HIV means a lifetime of antiviral therapy. We can control the infection with those drugs, but we haven't been able to cure people by ridding the body completely of the virus. But thanks to a new study published in Molecular Therapy by scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University and the University of Pittsburgh, all that may change.
Tardigrades are some of the toughest but least well-known creatures on our planet. These tiny animals, also called moss piglets or water bears, are definitely of this earth, but some can boast that they've also traveled to space.
Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.
Google Home now helps users to discover new music with an added "Listen" tab in the app. The feature offers suggestions based on the Cast-enabled apps on a phone, while offering other apps to download if you'd like to broaden your musical horizons. The playlists are curated to your individual taste and will adjust for different artists and activities, which is a pretty nifty feature. This means that Google Home can cater to your momentary mood change with music, which is a welcome addition to...
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
Lighthouses and signal fires may have been the first social media. Without the ability to share language, a distant light meant "humans here." A new study from the University of California, San Diego, finds that bacteria can also send out a universal sign to attract the attention of their own, and other bacterial species.
Findings from a mouse study suggest that the Zika virus infection may have serious reproductive consequences for men.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
It's a given that if you're driving, you or someone you know has Waze as a go-to on their smartphone. The Google-owned crowdsourced navigation app is one of the best for avoiding traffic, roadblocks, and even cops.
Using a fingerprint scanner to keep intruders out of your phone might not be as secure as you think. Two researchers from Michigan State University, Kai Cao and Anil K. Jain, developed a relatively cheap and effective way to beat fingerprint readers, and successfully tested their method on a Samsung Galaxy S6 and Huawei Honor 7.
Using a technology we like to call "Hive Computing," several Android apps allow you to contribute idle processing power to help further scientific research. This basically means that when you're not using your phone or tablet, it can join forces with other idle devices to form a supercomputer that scientists can use to potentially make a world-changing breakthrough.
Nothing gets me functioning in the morning better than strong coffee. And if I'm going to start my day with a dreaded workout, that steaming cup of caffeine is the exact motivation I need to get going. Although coffee might not seem like the best beverage to drink before hitting the gym, it actually has a few hidden benefits over water that may surprise you.
Until recently, brainwave-reading devices have pretty much only existed in science fiction. Sure, electroencephalography (EEG), the technology that powers these devices, has been used in medicine and psychiatry since the late 1800s, but diagnosing people's brains and reading their minds are two totally different things. The first EEG headsets available to the public were used mostly in gaming and even in fashion, but in the last few years, they've gotten a little more sophisticated.
At the recent DefCon conference in Las Vegas, researchers opened many of the top commercially available gun safes with simple tools like a straw or a paper clip, and in one case, just by shaking it a bit. The investigation began after the researchers, Toby Bluzmanis, Marc Tobias and Matt Fiddler, learned that certain Stack-On safes, issued to some law enforcement officials to secure their firearms at home, could be opened simply by jiggling the doorknob.
According to a study released 6/24/08 by PLoS Medicine, watching a video in an STD clinic waiting room can reduce the risk for a new STD by almost 10%. In a large multi-center intervention trial, Dr. Lee Warner from the Centers for Disease control and Prevention and a team of researchers at different institutions in the U.S. studied the effect of a carefully crafted, 23-minute waiting room video on the risk for new STDs among 40,000 patients in 3 STD clinics in the country. This is brought to...
