Aging and Bloated OpenSSL Is Purged of 2 High-Severity Bugs

Slashdot - 35 min 50 sec ago
An anonymous reader cites a story on Ars Technica: Maintainers of the OpenSSL cryptographic library have patched high-severity holes that could make it possible for attackers to decrypt login credentials or execute malicious code on Web servers. The updates were released Tuesday morning for both versions 1.0.1 and 1.0.2 of OpenSSL, which a large portion of the Internet relies on to cryptographically protect sensitive Web and e-mail traffic using the transport layer security protocol. OpenSSL advisories labeled the severity of both vulnerabilities "high," meaning the updates fixing them should be installed as soon as possible. The fixes bring the latest supported versions to 1.0.1t and 1.0.2h. The decryption vulnerability is the result of what cryptographers call a padding oracle weakness, which allows attackers to repeatedly probe an encrypted payload for clues about the plaintext content inside. According to TLS expert Filippo Valsorda, the bug allows for only 16 bytes of encrypted traffic to be recovered, and even then only when an end user sends it repeatedly.

Parental roles matter in fostering relationships between children, stepgrandparents

Science Daily - 1 hour 2 min ago
Researchers are shedding new light on what happens within a family when the stepgrandparent had no active role in raising the parent of the stepgrandchild. Their findings indicate that how a parent behaves toward the stepgrandparent determines the relationship between their child and the stepgrandparent.

Ketamine lifts depression via a byproduct of its metabolism

Science Daily - 1 hour 4 min ago
A chemical byproduct, or metabolite, created as the body breaks down ketamine likely holds the secret to its rapid antidepressant action. This metabolite singularly reversed depression-like behaviors in mice without triggering any of the anesthetic, dissociative, or addictive side effects associated with ketamine. The discovery fundamentally changes scientists' understanding of how this rapid antidepressant mechanism works and holds promise for improved treatments.

'Bugs' as drugs: Harnessing novel gut bacteria for human health

Science Daily - 1 hour 4 min ago
Scientists have grown and catalogued more than 130 bacteria from the human intestine. Imbalances in our gut microbiome can contribute to complex conditions and diseases such as obesity, inflammatory bowel disease, irritable bowel syndrome and allergies. This research will enable scientists to understand how our bacterial 'microbiome' helps keep us healthy and start to create tailor-made treatments with specific beneficial bacteria.

Star with different internal driving force than the sun

Science Daily - 1 hour 4 min ago
A star like the sun has an internal driving in the form of a magnetic field that can be seen on the surface as sunspots. Now astrophysicists have observed a distant star in the constellation Andromeda with a different positioning of sunspots and this indicates a magnetic field that is driven by completely different internal dynamics.

Equilibrium modeling increases contact lens comfort

Science Daily - 1 hour 4 min ago
Researchers have designed an equilibrium model to demonstrate the elastic stresses and suction pressure distribution between a soft hydrogel contact lens and an eye. The model allows arbitrary (radially-symmetric) lens shapes, eye shapes, and thickness profiles, and illustrates the dependence of pressure distribution on lens and eye shape.

Venus flytrap exploits plant defenses in carnivorous lifestyle

Science Daily - 1 hour 7 min ago
Venus flytraps have fascinated biologists for centuries, however, the molecular underpinnings of their carnivorous lifestyle remain largely unknown. Researchers have now characterized gene expression, protein secretion, and ultrastructural changes during stimulation of Venus flytraps and discover that common plant defense systems, which typically protect plants from being eaten, are also used by Venus flytraps for insect feeding.

High-fructose diet during pregnancy may harm placenta, restrict fetal growth

Science Daily - 1 hour 7 min ago
Research in mice and women found that consuming a high-fructose diet during pregnancy may cause defects in the placenta and restrict fetal growth, potentially increasing a baby's risk for metabolic health problems later in life. However, the generic drug allopurinol, frequently prescribed to treat gout and kidney stones, appears to mitigate the negative maternal and fetal effects.

Study shows pain causes older adults to develop more inflammation over time

Science Daily - 1 hour 7 min ago
When older relatives complain about their pains, show a little empathy, because new research suggests that as we age, we may all become more sensitive to pain. A small, preliminary study has suggested for the first time that inflammation may occur more quickly and at a higher magnitude -- and stays around longer -- when older adults experience pain versus when younger adults experience pain.

Windows 10 Updates Are Now Ruining Pro-Gaming Streams

Slashdot - 1 hour 15 min ago
An anonymous reader cites a report on The Guardian: Perhaps there's nothing more annoying than going in for the kill to suddenly be "pooped on" by a Windows 10 automatic installation taking out your computer mid-stream to your 130,000 or so followers. After deciding to advertise during the weather by attempting to automatically install midway through a forecast, Windows 10 is starting to wreak havoc with gamers. Ex-professional Counter Strike player turned full-time streamer Erik Flom was rudely interrupted mid-game and live on Twitch by Windows 10 automatically installing on his PC. "What. What!? How did this happen! Fuck you Windows 10!" Flom said. "Oh my God! You had one job PC. We turned off everything. Update faster you fuck!"

Are We Alone In the Universe? Not Likely, According To Math

Slashdot - 1 hour 55 min ago
An anonymous reader writes: An equation, which calculates the probability of the evolution of other technological civilizations, has found that it's wildly unlikely we're the only time advanced society in the universe. Adam Frank from the University of Rochester and Woodruff Sullivan from the University of Washington base their new equation on the Drake equation, used for calculating the probability of extraterrestrial civilisation, written by astronomer and astrophysicist Frank Drake in 1961. The scientists also take into account Kepler, which suggests that one in five stars have planets in the habitable zone. Frank and Sullivan calculated that human civilisation is only unique if the odds of a civilisation developing on a habitable planet are less than one in 10 billion trillion. "One in 10 billion trillion is incredibly small. To me, this implies that other intelligent, technology producing species very likely have evolved before us," Frank said. Frank said: "Of course, we have no idea how likely it is that an intelligent technological species will evolve on a given habitable planet. But using our method we can tell exactly how low that probability would have to be for us to be the ONLY civilization the Universe has produced. We call that the pessimism line. If the actual probability is greater than the pessimism line, then a technological species and civilization has likely happened before."

John Kasich To Drop Out, Leaving Trump as GOP Nominee

Slashdot - 2 hours 35 min ago
Multiple outlets are reporting that Ohio Gov. John Kasich plans to suspend his run to be the GOP presidential nominee. The move, if happens, would make Donald Trump the presumptive nominee for the GOP. The report comes hours after Kasich abruptly cancelled a planned press conference (could be paywalled; alternate source) in Virginia on Wednesday morning. LA Times reports: Kasich, the Ohio governor, had pledged to continue campaigning as a Trump alternative who could deny the billionaire needed delegates. But on Wednesday, he canceled a news conference in Washington and planned an announcement for later in the day in Columbus, Ohio, to drop out. Vox has more details.
