Computer scientists discover vulnerabilities in a popular security protocol
2024-08-20
A widely used security protocol that dates back to the days of dial-up Internet has vulnerabilities that could expose large numbers of networked devices to an attack and allow an attacker to gain control of traffic on an organization's network.
A research team led by University of California San Diego computer scientists investigated the Remote Authentication Dial-In User Service (RADIUS) protocol and found a vulnerability they call Blast-RADIUS that has been present for decades. RADIUS, designed in 1991, allows networked devices such as routers, switches or mobile roaming gear to use a remote server to validate login or other credentials.
This is a common set-up in enterprise and ...

A new reaction to enhance aromatic ketone use in chemical synthesis
2024-08-20
Aromatic ketones have long been valuable intermediates in chemical synthesis, particularly in cross-coupling reactions where different chemical entities are combined to form new compounds. For instance, a process called deacylative cross-coupling removes the acyl group from the aromatic ketone, allowing it to bond with other chemicals and produce a wide variety of useful compounds. These reactions are crucial for producing a wide array of aromatic compounds used in various industries like agrochemicals.
However, the utility of aromatic ketones has been limited due to the difficulty in breaking their strong carbon-carbon bonds. These robust bonds are challenging to cleave, ...
Investigating the interplay of folding and aggregation in supramolecular polymer systems

Fossil hotspots in Africa obscure a more complete picture of human evolution
2024-08-20
WASHINGTON (August 20, 2024) – Much of the early human fossil record originates from just a few places in Africa, where favorable geological conditions have preserved a trove of fossils used by scientists to reconstruct the story of human evolution. One of these fossil hotspots is the eastern branch of the East African Rift System, home to important fossil sites such as Oldupai Gorge in Tanzania. Yet, the eastern branch of the rift system only accounts for 1% of the surface area of Africa—a fact that makes it possible to estimate how much information scientists who rely on such small samples are missing.

Extraterrestrial chemistry with earthbound possibilities
2024-08-20
DENVER, Aug. 20, 2024 — Who are we? Why are we here? As the Crosby, Stills, Nash & Young song suggests, we are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules — the seeds of life on Earth and possibly elsewhere — researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and environmental applications on our home planet.
Undergraduate student Kennedy Barnes will present the team’s results at the fall meeting of the American ...

Planets contain more water than thought
2024-08-20
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets – planets that orbit another star outside our solar system. “It is only in recent years that we have begun to realise that planets are more complex than we had thought,” says Caroline Dorn, Professor for Exoplanets at ETH Zurich.
Most of the exoplanets known today are located close to ...
Blood platelet score detects previously unmeasured risk of heart attack and stroke
2024-08-20
Platelets are circulating cell fragments known to clump up and form blood clots that stop bleeding in injured vessels. Cardiologists have long known that platelets can become “hyperreactive” to cause abnormal clotting that blocks arteries and contributes to heart attack, stroke, and poor blood flow (peripheral artery disease) in the legs of millions of Americans.
Despite this major contribution to cardiovascular risk, routine measurement of whether each patient’s platelets clump (aggregate) too much has been infeasible to date. ...

Novel ratchet with geometrically symmetric gear driven by asymmetric surface wettability
2024-08-20
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typically consisting of a gear and a pawl, which restricts the movement of the gear in one direction. In biological systems, the concept of a Brownian ratchet has been proposed to help understand the mechanism of molecular motors, where chemical reactions rectify the random thermal motion of molecules.
According to the second law of thermodynamics, uniform thermal ...
