Determining what’s real online is getting more difficult. But there are steps you can take to deal with it.

Hackers are able to grab a target’s IP address, potentially revealing their general physical location, by simply sending a link over the Skype mobile app. The target does not need to click the link or otherwise interact with the hacker beyond opening the message, according to a security researcher who demonstrated the issue and successfully discovered my IP address by using it.

Yossi, the independent security researcher who uncovered the vulnerability, reported the issue to Microsoft earlier this month, according to Yossi and a cache of emails and bug reports he shared with 404 Media. In those emails Microsoft said the issue does not require immediate servicing, and gave no indication that it plans to fix the security hole. Only after 404 Media contacted Microsoft for comment did the company say it would patch the issue in an upcoming update.

The attack could pose a serious risk to activists, political dissidents, journalists, those targeted by cybercriminals, and many more people. At minimum, an IP address can show what area of a city someone is in. An IP address can be even more revealing in a less densely populated area, because there are fewer people who could be associated with it.

Spacecraft finds sulphur and other elements as it looks for signs of frozen water nearly a week after historic landing.

In an era of growing digitalisation, data centers have emerged as the fundamental support of our technological framework. However, worries persist over the ecological effects due to their swift growth and power-demanding activities. These data centers rank among the planet’s most energy-intensive establishments, drawing substantial electricity to fuel servers, cooling mechanisms, and auxiliary apparatus vital for their operations. Such elevated energy usage significantly affects the environment by adding to greenhouse gas discharges and ushering climate change.

The AI Power Consumption Challenge

The growing surge of AI (Artificial Intelligence) in recent years has been a remarkable and transformative phenomenon. However, AI models and algorithms are highly resource-intensive and consume significant amounts of power. Training AI models involve massive computational workloads, often requiring specialised hardware accelerators like GPUs, which consume substantial energy. This power consumption is a major concern when it comes to making data centers greener.

Antipsychotic drugs treat incredibly vulnerable patients. Maintaining a treatment regimen is difficult for many patients, but not taking the medication is associated with a higher risk of poor health outcomes. These drugs are also very powerful with strong side effects, and blood tests are often used to calibrate a patient’s dosage and confirm that they are taking the recommended dose.

However, blood tests are invasive and potentially uncomfortable. Scientists have now discovered a way to test the levels of common antipsychotic drugs in the sweat from patients’ fingerprints, offering a quicker, more comfortable, and more convenient alternative to blood draws for patient monitoring.

“Our test offers patients a quick and dignified way of showing commitment to antipsychotic treatment,” said Katherine Longman of the University of Surrey, first author of the study in Frontiers in Chemistry. “This non-invasive approach can also be adapted to fit other therapeutic regimes.”

The Laser-Induced Breakdown Spectroscopy (LIBS) instrument onboard Chandrayaan-3 Rover has made the first-ever in-situ measurements on the elemental composition of the lunar surface near the south pole. These in-situ measurements confirm the presence of Sulphur (S) in the region unambiguously, something that was not feasible by the instruments onboard the orbiters.

LIBS is a scientific technique that analyzes the composition of materials by exposing them to intense laser pulses. A high-energy laser pulse is focused onto the surface of a material, such as a rock or soil. The laser pulse generates an extremely hot and localized plasma. The collected plasma light is spectrally resolved and detected by detectors such as Charge Coupled Devices. Since each element emits a characteristic set of wavelengths of light when it’s in a plasma state, the elemental composition of the material is determined.

Preliminary analyses, graphically represented, have unveiled the presence of Aluminum (Al), Sulphur (S), Calcium (Ca), Iron (Fe), Chromium (Cr), and Titanium (Ti) on the lunar surface. Further measurements have revealed the presence of manganese (Mn), silicon (Si), and oxygen (O). Thorough investigation regarding the presence of Hydrogen is underway.

Apple Inc. is testing the use of 3D printers to produce the steel chassis used by some of its upcoming smartwatches, according to people with knowledge of the matter, heralding a major change to how the company manufactures products.

Here’s everything you need to know about the Dolby Atmos FlexConnect.

Coming to a tight spot near you: CLARI, the little, squishable robot that can passively change its shape to squeeze through narrow gaps—with a bit of inspiration from the world of bugs.

CLARI, which stands for Compliant Legged Articulated Robotic Insect, comes from a team of engineers at the University of Colorado Boulder. It also has the potential to aid first responders after major disasters in an entirely new way.
