An international team has been exploring remote monitoring with the help of two antennas and a couple of mirrors.

These 'biological fingerprints' can reveal what minerals are buried tens of meters below the earth's surface without having to drill. The researchers believe it is the first use of modern DNA sequencing of microbial communities in the search for buried minerals. The research represents a new tool for mineral exploration, where a full toolbox could save prospectors time and a lot of money, Tue, 24 Oct 2023 23:40:34 EDT https://www.sciencedaily.com/releases/2023/10/231024234034.htm https://www.sciencedaily.com/releases/2023/10/231016122811.htm Forensic fibers can survive underwater for much longer than previously thought -- which could help criminal investigators uncover vital evidence. New research has found that fiber evidence can survive on fabrics underwater for several weeks.

Finding and reporting a mismatch can help free the innocent, just as a match can incriminate the guilty. But new research reveals mismatches are more likely than matches to be reported as 'inconclusive' in cartridge-case comparisons.

An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.
