Hackers can use popular Google searches to trick people into revealing their personal information or transferring money to them.
The founder of the cybersecurity company TorGuard, Ben Van Pelt, spoke to the British portal Indy100 about which queries on Google can be dangerous.
- Customer support
Ben Van Pelt noted that scammers can buy advertising to get their websites to appear at the top of search results. They post misleading links and phone numbers on these sites. He warned that attackers can convincingly impersonate technicians over the phone, so he advises that you should always look for companies’ contact information only on their official websites.
- Quick loans
According to Ben Van Pelt, scammers may also advertise easy and quick loans online to exploit the trust of people in financial difficulties. They often ask for advance payments and access to personal data, but in the end the money may never arrive in the account.
“Instead of turning to Google for financial help, it’s better to turn to reputable banks and lenders,” the expert advises.
- Quick profit
Ben Van Pelt warns that offers of “investment opportunities” promising high returns are often disguised as pyramid schemes. He recommends seeking advice from trusted investment brokers or financial advisors.
- Remote work with high earnings
According to him, to find a job, it is better to use well-known job sites and official company websites, rather than searching for the query “high-paying remote work” on Google. Job openings that may result from such a request may be used for illegal activities or to collect personal and financial information.
- Free credit report
Ben Van Pelt warns that scammers may offer to run a free credit report to obtain all of a person’s personal information, including date of birth and Social Security number.
- Technical support
Fraudsters can also create fake technical support services to gain remote access to computers and install malicious software or obtain credit card information. The expert advises contacting official technical support from the device manufacturer or software supplier.

Study sheds light on the formation of human embryos
Paris. A group of researchers has revealed the mechanisms by which the first cells amalgamate to form the embryo, a discovery that sheds new light on the first stages of human life.
This is the “first study on the mechanics of morphogenesis of the human embryo,” summarizes the work published this Wednesday in the journal Nature.
A few days after fertilization, when the encounter between the sperm and the egg has already given rise to a stem cell, which has divided into about ten more cells, these come together and agglutinate to form a single unit: it is the embryo in its earliest phase.
Only after that moment will the cells differentiate, gradually giving rise to organs and then to a human form.
This first stage, called “compaction”, is crucial. It is the object of this study, carried out mainly by researcher Julie Firmin and in which the National Center for Scientific Research (CNRS) of France, the National Institute for Research in Health and Medicine (Inserm) and the Curie Institute participated.
Until now, it was thought that the main mechanism of embryo formation was that by which cells stick together, through the adhesion of their walls.
However, according to this study, this factor only plays a secondary role. The most crucial thing is the contraction capacity of each cell, the mechanism by which they pull towards each other.
“You have to imagine a circle of people holding hands” that is closing little by little, he explains to Afp researcher Jean-Léon Maître, who supervised the study.
To reach this conclusion, the researchers examined the cells of several embryos left over from in vitro fertilization and frozen in different phases between three and five days.
The more advanced its state, the greater the contraction capacity of its cells, while the degree of adhesion of the walls remained stable.
Important progress
“What makes the cells stick together is not the amount of glue, but these contraction efforts,” insists Maître, adding that “it is not at all a surprise.”
In the last 20 years, several studies have revealed similar mechanisms in flies and mammals such as mice, although the details vary between animal species and humans.
The study published this Wednesday allows us to better understand the human embryo, although very specific consequences cannot be expected immediately.
It is conceivable that this knowledge will one day facilitate the formation of embryos for in vitro fertilization.
Currently, we choose to implant embryos that have successfully passed this training phase.
This study also marks an important advance in our knowledge of the beginning of human life, an area of research that has accelerated in recent years.
This also includes the recent production of embryo-like structures in the laboratory by several research teams.
These structures, sometimes called “synthetic embryos” although the term is controversial, should allow us to study how cells and then organs differentiate during the first weeks of gestation.
Like these works, the new study aims above all to better understand how a human organism is built, what makes it similar to other animals and what distinguishes it.
It is about, this work concludes, “discovering how nature uses the laws of physics to produce so many forms of life, with their astonishing diversity.”

Good news for the hearing impaired, new sensor introduced
Sensors are currently being used extensively in a number of important applications, such as monitoring infrastructure such as buildings or bridges, or key technologies such as gadgets to assist the hearing impaired.
But due to the need for a constant power supply in these sensors, they rely on batteries that need to be replaced regularly, leading to massive accumulation of electrical waste.
According to a European Union study, by 2025, 7.8 million batteries will be thrown into the garbage every day. These batteries are made of materials that can be difficult to collect and dispose of.
Recently, scientists from Switzerland have claimed to have developed a sensor that has the ability to eliminate the jitters of batteries.
In a recent study at ETH Zurich, researchers say they have created a mechanical sensor that requires no energy to operate and could help reduce battery waste.
Johan Robertson, one of the leaders of the research, said that the sensor uses the vibrational energy contained in sound waves.
This sensor is able to process specific sound (pronunciation of a specific word or production of a specific sound). A specific set of sound waves causes the sensor to vibrate, which means the sensor has been activated.
